A
So
that
was
one
angle,
but
basically,
if
you
have
a
foundation
like
that,
it's
like
one
after
another,
we
didn't
bother
about
the
bottom
plate,
because
the
foundation
itself
is
is
even
enough.
It's
I
mean
it's
not
perfectly,
even
but
it's
decent
enough,
so
that
we
can
put
together.
A
A
We
are
connecting
through
each
module,
so
like
five
screws
per
the
holding
capacity
of
one
screw
is
about
300
pounds
on
the
corners
you
want
to
do.
The
corners
are
most
sensitive.
You
want
to
button
those
ups,
so
the
proper
schedule
there
would
be
like
every
eight
inches
or
so
for
the
corners.
I
would
recommend
if
you
want
something
that
withstands
like
really
high
winds
and
stuff
like
that,
so
definitely
not
like
just
two
screws,
like
I
saw
people
left
the
corners
at
two
screws,
some
of
them.
A
You
want
to
button
that
up
quite
firmly
we're
just
using
the
one
stud
into
another
in
the
cd
cajon.
We
have
that
nailing
plate
concept
where
we're
paying
more
attention
to
the
corners
for
higher
wind
speeds,
but
yeah
attaching
the
the
glazing.
A
All
the
glazing
is
actually
from
the
last,
the
second
aquaponic
greenhouse
the
polycarbonate
lasts
for
decades.
It's
like
a
decade
or
two,
it's
a
pretty
good
material.
It's
advantages.
It's
also
3d
printable,
quite
well,
3d
printable.
So
what
you
saw
with
that
that
pla
print
that
I
did
man,
it's
it's
right
there.
We,
if
we
have
the
material
that
we're
making
filament
at
low
cost.
Where
do
you
get
that.
A
B
Does
pla
have
any
decent
uv
resistance,
almost
kind
of
strong.
C
A
A
A
You
might
lose
a
little
bit,
but
I
mean
the
polycarbonate
already
is
like
85
and
that's
plenty
of
sun.
It's
that's
a
lot
of
sun,
like
plants,
aren't
sun
limited
typically
in
a
greenhouse
like
that
or
typically
in
a
winter
they're
temperature
limited
if
you're
talking
about
year-round
production,
so
they
also
make
this
just
polyethylene
translucent
polyethylene.
A
A
So
the
one
that's
now
used
as
a
storage
structure,
we
had
the
whole
thing
actually
slide.
So
just
put
like
a
rail
instead
of
the
battens
buttoning
down,
you
put
one
batten
and
then
another
one
over
the
top.
So
you
have
a
long
rail
and
we
actually
slid
the
whole
thing
that
works,
but
I
mean
it's
over
time.
We
kind
of
had
it
hanging
by
wire,
but
that
whole
four
foot
wide
length
like
after,
like
three
or
four
years.
A
The
winds
just
blew
that
off
started
blowing
it
off,
even
though
we
kind
of
haven't
pinched
on
the
sides.
So
then
we
screwed
it
down,
and
then
by
that
time
it
was
degraded
enough
that,
when
kept
on
picking
it
up
but
yeah,
you
gotta
attach
this
firmly.
So
the
way
we're
gonna
do
the
the
windows
it
are
up
there,
we're
going
to
do
a
small
section.
A
That's
sliding
all
you
need
is
a
small
section
for
that
that
airflow,
so
we
we're
leaving
a
two
foot
section,
that's
openable
at
the
very
top,
and
as
I
mentioned,
I
like
the
very
bottom
to
have
so
you
can
have
this
natural
cross
crosswind,
because
the
thing
that
that's
in
the
greenhouse
you
either
have
mechanical
air
pumping
like
wind
flow
airflow.
A
Otherwise,
you
get
all
kinds
of
you
get
a
lot
of
mold
and
fungus,
and
and
aphids
like
they
love
the
moist
environment.
So
part
of
it.
Is
you
really
want
to
keep
that
greenhouse
like
not
dripping
a
hundred
percent
but
a
little
below,
because
it
will
get
to
a
hundred
percent
easily
if
you
close
up
all
the
windows
like
all
the
water
in
there,
the
plant,
transpiration
of
say,
a
thousand
plants,
that's
huge!
That's
just
as
much
as
a
water
water
as
a
plant
takes.
A
I
I
don't
know
the
exact
figure
but,
like
I
would
guess,
like
a
gram
or
two,
how
much
water
does
a
lettuce
use
per
day.
A
E
Hello,
no
one
can
hear
you
on
the
channel.
A
One
cubic
inch
is
like
16
grams
one
cubic
foot.
Well,
let's
take
one
cubic
inch.
So
if
you
have
an
inch,
that's
quite
a
bit
of
weight,
inch
inch
of
water
weight,
one
gram
per
day
per
something
like
that
is
that
are
you
getting
that.
F
From
somewhere
or
just
about
0.15,
every
inch.
A
F
A
Yeah,
I'm
getting
every
inch
is
five
pounds
over
a
square
foot,
so
yeah
like
a
six,
would
be
about
a
gram,
no
one.
No
that
says
one,
I'm
not
getting
it.
How
are
you
oh
yeah,
one
cubic
centimeter
yeah
this.
This
estimate
here
is,
if
you
what
so,
actually,
let's
talk
about
how
much
land
plants
use.
So
this
is
like
relevant
to
desert.
The
point
about
the
aquaponics
is
you're
constantly
recycling
that
water,
especially
if
you
could
have
like
a
maybe
a
dehumidifier,
that's
solar-powered!
A
That's
in
there
that's
trapping
your
water
all
the
time
or
even
generating
the
atmospheric
water
at
30
liters
per
day.
If
you
can
afford
the
2
000
machine,
which,
if
you
open
source
it
it'll,
be
much
lower
than
that,
because
it's
it's
just
a
bunch
of
plumbing
so
plus
a
refrigeration,
it's
a
refrigerator
plus
a
bunch
of
plumbing,
so
you
got
to
cool
it.
Yeah
it'll
be
like
a
compressor
like
in
a
fridge,
but
how
much
is
a
fridge
like
100
bucks?
A
A
But
with
3d,
printing
and
all
else,
you're
you're
good
to
go
to
once
again
3d
printed
appliances
are
a
great
potential
or
power
tools,
huge
potential
there.
If
one
inch
weighs
five
pounds.
If,
if
lettuces
are
taking
a
sixth
of
an
inch
or
0.15
it's
about
a
pound
per
day,
man,
that
is
huge.
That's
for
for
earth,
I'm
assuming
that's
earth
grown,
but
we've
got
20
lettuces
per
square
foot.
A
We
can
explore
that
number
in
more
detail,
but
you're
gonna
have
to
like
count
your
water
like.
If
you
have
expensive
water,
I
mean
water,
is
gonna,
be
a
cost
for
agriculture,
if
you're
irrigating,
even
in
aquaponics,
but
think
about
now,
probably
like
10x
less,
because
it's
an
enclosed
system
and
it
uses
water
more
efficiently,
because
the
number
one
loss
of
water
in
agriculture
is
just
evaporation.
A
Most
of
the
water
goes
away
into
the
atmosphere
once
you
water,
I
mean
you
try
to
water
at
night,
of
course,
but
still
there's
a
whole
bunch
of
evaporation
that
takes
place
just
like
just
to
keep
the
soil
moist
during
the
day.
It
just
all
evaporates-
I
mean
the
sun,
so
in
an
aquaponic
system,
you've
got
the
ponds
of
water,
which
are
pretty
much
hidden,
so
the
the
only
loss
is
transpiration,
not
evaporation.
A
So
how
much
more?
How
much
more
water
efficient
is
aquaponics.
It's
like
five
or
ten
times
how
much
more
efficient
is
aquaponic.
Yeah
yeah,
like
ten
times
water,
yeah
10
times
more
productive,
well,
productive!
Well!
That
also
means,
if
you
got
10x
productivity,
but
then
also
you
got
less
so
you've
got
first
of
all
more
productivity,
but
second
for
a
given
area
and
evaporation
that
the
term
depends
on
the
area.
You
have
right
so
you're
getting
10x
right
there
for
productivity
and
and
more
for
the
actual
transpiration,
only
not
evaporation.
A
That's
like
100.,
so
that's
where
we
like
that
10x
100x!
That's
that's!
In
line
with
how
we
want
to
think
because
abundance
is,
you
can
never
have
like
a
greedy
person
or
a
waste
in
a
an
area
of
abundance.
I
mean
that
still
requires
that
people
are
using
things
efficiently,
like
the
kind
of
idea
of
ancient
wisdom.
Modern
technology
like
as
soon
as
you
start
wasting
stuff,
no
matter
how
much
you
have
you're
always
going
to
be
short.
It's
always
have
to
have
the
wisdom
to
use
resources
efficiently
to
grow.
A
So
we
talked
about
the
the
windows.
We
can
do
that
temperature,
so
we
got
got
to
here.
It
was
kind
of
cool
how
this
actually
the
six
foot
walls
that
that
was
super
easy
because
they
weren't
so
tall.
So
it
was
easy
to
put
these
things
up
there
relatively
easy
and
then
screwing
in
from
the
bottom.
So
we
got
a
good
connection
from
the
bottom.
We
first
put
them
together,
so
once
you
put
them
on
top
put
them
together,
so
you
eliminate
those
cracks
in
between
those.
A
That's
a
long
crack
like
insects
will
get
through
that.
So
the
important
thing
is
you
wanted
this
as
much
airtight
as
possible,
so
here
we
still
have
to
do
the
triangular
sections.
So
for
that
we
would
take
two
by
six
and
do
a
basically
a
triangular
truss.
So
two
two
long
sixteen
footers
we
can
do
do
we
have
some
sixteenths.
If
we
don't,
we
can
use
like
two
by
fours.
A
A
That
is
also
insecticidal,
so
it
it
tends
to
it's
all
about
promoting
the
plant
health
and
at
which
point
if
plants
are
very
healthy,
they
can
resist
a
lot
of
things,
but
as
soon
as
they
get
weak,
they
get
attacked
completely
and
in
artificial
systems
you
typically
kind
of
tend
to
breed
less
resilient
organisms.
So
the
resilience
part
the
strength
of
the
plant.
That's
like
literally
the
only
the
the
main
thing
you
want
to
go
for.
A
H
Glazing
didn't
line
up
properly
with
the
modules
everywhere.
It
might
just
be
the
foundation
that
makes
the
rest
like
sort
of
unplumbed
they're
all
on
there.
It's
tight
enough.
A
A
You
got
all
the
weight
of
the
water
most
of
the
weight
of
the
water
at
the
bottom
and
after
that
we
actually
reinforce
the
corners
because
that's
like
those
screws
can
pull
out
like
if
you're
going
into
the
end
grain,
because
on
one
side,
when
we
screw
the
box,
basically
like
this
at
some
point
you
have
to
screw
through
the
end
grain
and
that's
a
very
weak
connection.
You
typically
want
to
be
going
cross
grain
in
wood,
but
the
end
grain
screws
they
pull
out
much
easier.
A
A
So
typically,
we
like
to
do
them
at
a
small
angle,
so
you
don't
because
that
will
puncture
your
polyethylene
water
barrier,
we'll
do
a
double
layer,
polyethylene
barrier,
so
it
has
kind
of
like
double
the
resiliency
and
that
should
it
works
well,
I
mean,
may
not
be
like
lifetime
design
of
like
a
hundred
years,
because
you
know
something
falls
on
a
polyethylene.
You
might
get
a
break
in
it
or
whatever,
but
it's
works
for
a
number
of
years.
A
It's
a
very
low
cost
thing
next
step
up
being
things
like
epdm
like
or
like
roof
pond
liner
roof
liner
like
what
we
actually
use
on
the
house.
That's
like,
I
believe,
that's
20
or
40,
mil
much
thicker,
so
it
it'll
just
last
long,
would
last
longer
like
they
do
permanent
ponds
with
the
pond
liners
which
are
epdm
typically.
A
So
beyond
that,
what
else
do
we
want
to
do
on
a
pond?
So
it's
three
feet
high
about.
We
do
want
to
put
a
bar
across
it,
like
I'm,
suggesting
a
piece
of
rebar
weld,
two
angles
on
top
and
just
screw
it
into
the
side.
So
just
a
little
weld
job
there.
We
can
do
that
real,
quick,
but
something
that
holds
the
the
middle
from
bulging
out,
because
you
have
no
protection
against
this
kind
of
motion
right
now.
There's
nothing!
A
It's
the
strength
of
the
wood,
but
the
wood
is
quite
flexible
along
the
little
long
direction.
It
will
bow
out
and
weaken
the
joints.
Richard
was
asking:
can
you
just
those
joints
up?
Well
in
a
wood
in
a
wood
structure,
the
wood
will
move.
You
cannot
do
simple,
caulking
or
like
some
kind
of
a
like
plastic
seal,
because
the
wood
will
just
move
too
much.
It's
like
it
expands
and
shranks.
A
A
They're
structural
they're,
just
heavy
just
heavy
weight
and
that's
they're,
not
gonna
move.
So
if
we
did
a
round
pond
go
ahead,
ken.
A
H
About
you
know
when
you
do
building
how.
A
D
D
C
F
I
think
I
need
like
some
like
cedar
they'll,
not
find
that
they're
using
two
by
fours
yeah.
It's
not
really
meant
to
be
yeah
like
that,
because
they
built
like
also
like
hot
tubs
and
saunas
out
of
cedar
too
yeah
and
again
they
they
yeah.
They
came
already
pretty
high
in
moisture
yeah
without
a
liner
you,
but
you
have
to
use
a
steel
band
to
close
them,
because
you
need
that
pressure
or
what
about?
How
do
they
do
barrels
safety
same
way?
Yeah
yeah,
no.
B
So
you're
playing
like
you,
have
to
be
wondering
like
how
not
how
it
cools.
Maybe
I'm
wondering
if
I
use
it
I'm
trying
to
make
it
tough
as
well.
If
I,
if
I
did,
use
the
ep
in
the
line
or
something
like
that,
how
would
you
put
any
type
of
additional
materials?
On
top
of
that?
You
have
to
you,
know,
use
adhesives
or
something
I'm
just
trying
to.
B
A
With
a
liner,
you
get
into
the
issue
that,
if
you're
attaching
anything
mechanically,
then
you're
poking
through
the
liner,
so
that
won't
do
it.
You'd
have
to.
I
mean
typical
thing
for
pools.
It's
it's
concrete
and
tile,
so
con
concrete,
then
some
kind
of
a
backing
for
the
tile
like
how
do
they
do
pools?
A
A
Who
said
that,
how
like
katrina's
the
pond
we
have
the
pool
there?
That's
pretty,
I
mean
it's
aesthetic,
but
you
can't
do
anything
after
the
liner.
That
would
penetrate
it.
So
that's
that's.
E
A
hard
one
right
that
was
part
of
the
trick
of
doing
this
pool
is
to
I
wanted
to
do
like
you.
Can
you
can
cut
into
the
liner
and
then
you
can
seal
it,
but
all
of
those
every
puncture
is
going
to
be
a
potential
leak
at
some
point,
so
I
for
me
the
challenge
was
trying
to
do
it
all
so
that
the
liners
aren't
punctured
at
all.
So
what
we
did
is
very
unusual
like
no
one
does
it
the
way
we
did
it
at
a
typical
pool.
E
Them
as
long
as
at
the
end,
what
you
end
up
is
with
stucco,
usually
they'll
do
like
cinder
blocks
that
have
rebar
through
them
and
they're
filled
with
concrete
and
then
in
the
end.
You
basically
apply
a
stucco
like
a
portland
cement,
stucco
to
it,
and
then
they
have.
You
can
put
the
tiles,
but
the
tiles
are
mostly
decorative
and
actually
they
will
be
problematic
to
find
leaks.
But
then
what
you
do
is
take
a
paint.
It's
just.
It's
basically
a
paint
that
seals
the
stucco
and
that's
what
seals
your
it's
a
specific
pull
paint.
E
That's
what
seals
your
pool!
I
would
have.
A
Yeah,
if
we
do
so
the
potential
like,
for
example,
cb
cisterns-
I
thought
about
that
long
time
ago,
but
if
you
use
the
basket
technique
the
the
stucco
with
mesh
on
both
sides,
you
do
a
good
job
on
a
stucco
and
you
paint
it
that
would
work.
That
would
be
a
good,
let's
say,
a
round
structure,
because
the
bricks
are
so
heavy,
but
you
got
to
pay
attention
like.
How
are
you
joining
to
the
floor
like?
Is
there
going
to
be
a
crack
there?
A
That's
going
to
leak
and
stuff
like
that,
so
you
you
want
to
have
probably
the
cbs
like
if
you
do
that,
bees
and
everywhere,
so
you
can
do
a
uniform
nice
coat
of
stucco
on
it.
If
you
get
some
paint
on
it
or
some
kind
of
a
sealer
yeah,
I
mean
you're,
pretty
good,
I
mean
the
stucco,
that's
known
technology,
so
that
would
work
there'll
be
some
works.
That's
where
the
the
pond
liners
are
quite
convenient
for
an
easy
way
to
do
it.
A
So
thinking
thinking
also
about
the
larger
scale,
3d,
printing
or
3d
printable
structures
that
you
maybe
have
like.
I
was
thinking.
Okay.
How
do
we
do
that
pawn
and
it's
a
lot
of
work?
You
either
have
to
get
all
this
this
liner.
You
have
to
dig
this
big
hole.
You
have
to
stabilize
the
sides.
Well
say
we
had
the
hole
and
we
had.
We
had
to
stabilize
it.
What
do
you
do
so
3d
printed
sections
like
imagine,
you
can
print
like?
A
I
haven't
really
thought
much
about
it
outside
the
general
concept,
but
imagine
sections
that
you
can
print
and
then
you
can
make
long
structures
like
that
any
length,
so
you
can
do
whatever
you
want.
If
you
have
this
four
by
four
by
eight
size,
kind
of
a
printer
or
even
even
linear
planks
that
they
have
a
gasket
that
kind
of
like
slides
into
each
other.
I
see
you
got
this
kind
of
a
sliding
gasket.
J
A
A
Cool
thing
for
modularity
is,
if
you
can
print
the
complex
geometries
with
3d
printing
yeah,
you
can
do
you
can
make.
Those
connections
happen
like,
for
example,
for
domes
like
domes,
are
impossible
to
seal
up
properly.
I
mean
because
they've
got
all
the
triangles
and
all
that
it's
really
really
hard
job,
but
not
if
you
have
3d
printing
because
you
can
print
all
those
geometries.
So
once
again,
the
potential
for
3d,
printing
and
construction
is
is
great.
A
So,
let's,
let's
continue
any
other
observations
from
the
build
yesterday,
yeah
more
screws
like
screws
on
the
polycarbonate,
let's
actually
go
to
the
working
dock
and
just
talk
about
some
finishing
detail
like
quality
control,
so
we
make
sure
that
the
pond
doesn't
leak
that
we
don't
get
bugs
in
there,
so
so
water
tight
airtight,
but
not
so
watertight,
like
for
the
roof.
It's
fine!
A
If
you
get
dribbles
in
between
the
cracks
from
the
rain,
but
you
want
to
be
small
enough
that
you
don't
get
a
lot
of
bugs
going
in
there
like
mosquito
like
either
well,
I
mean
cabbage
moths,
I
mean
they're
big,
so
they
wouldn't
get
in,
don't
leave
more
than
like
a
millimeter
of
space,
so
things
don't
like
other
unwanted
animals,
don't
get
in
there
for
mice.
A
You
can't
have
a
hole
more
than
like
a
quarter
inch
because
baby
mice
get
through
that.
So,
for
example,
when
I
was
doing
the
nuts
that
greenhouse
wasn't
particularly
mouse
proof
and
it's
very
hard
to
mouse
proof,
a
structure,
any
structure-
you
have
to
be
very
careful,
but
there
we
had
to
just
set
a
ton
of
traps
everywhere
and
we
would
catch
mice
all
the
time
because
they
would
just
eat
all
your
nuts.
They
love
them.
They
smell
those
nuts
from
a
mile
away
and
it's
a
it's
a
mouse
magnet.
A
So
we
have
to
be
very
careful
about
having
a
bunch
of
traps
in
there.
So.
A
Well,
the
first
thing
would
be
like
see
if
you
can
button
them
up
with
with
screws,
but
other
than
that
I
mean
we
could
use
tape
like
like
the
how
about
using
the
the
house
wrap
tape.
That's
one
good
option.
Housewrap.
D
A
Yeah,
it's
the
red
stuff,
it's
not
the
white.
The
white
stuff
would
definitely
work.
That's
we
don't
need
to
do
that.
The
other
thing
is
just
let's
take
out
some
bug
screen.
You
could
staple
it.
If
there's
major
cracks,
you
could
caulk
it,
but
then
it's
gonna
be
hard
to
take
them
apart.
Yeah
just.
C
J
A
A
J
A
Yeah
we
have
those
the
pipe.
You
know
four
feet.
A
Yeah,
if
you
do
a
lot
of
clamping
strength,
that
would
be
a
heavy
heavy
3d
print,
but
yeah
yeah.
These
these
things
do
work
so
so
maybe
record
some
of
those
notes
here
so
after
this.
So
let's
talk
about
ceiling
for
bugs
seeing
structure
for
bugs.
A
A
A
A
I
Take,
for
example,
there's
pest
controls
through
spiders,
so
I
think
that's
a
that's
a
good
one.
A
Yeah,
there's
a
whole
world
of
complexity.
We
can
get
into
there
with
the
whole
biological
system.
A
I
Like
how
would
you
once
it's
gonna,
be
winter
you're
gonna
have
to
seal
it
against
right.
A
So
if
you
get
a
sunny
day,
it's
only
when
you
have
this
extended,
maybe
like
you
got
a
snow
and
it's
you're
not
getting
a
lot
of
sunlight
in
there
and
you've
got
like
a
week
or
two
of
cold
weather.
Then
you're
gonna
start
freezing
stuff
in
there,
but
short
of
that.
It's
it's
got
enough
thermal
mass
in
there,
but
what's
the
disadvantage
of
the
the
concrete
there?
That's
going
to
be
a
nice
heat
sink!
That's
for
the
winter!
That's
going
to
be
transporting
a
lot
of
cold,
because
it's
a
big
thermal
bridge
like
right!
A
Now
you
can
feel
the
concrete
it's
nice
and
warm.
So
it's
actually
good.
It
helps
you
out
for
a
little
bit
of
time,
but
then
it
traps
it
just
gets
cold
from
the
weather,
and
then
it
works
against
you
because
it's
like
on
the
bottom
of
the
pond.
We
should
actually
insulate
it
to
keep
it
out
of
that,
because
that's
going
to
be
like
freezing
as
cold
as
the
outside,
and
it's
pretty
much
going
to
transport
into
the
structure
outside
of
what
the
heating
does
inside
the.
A
Pv
pv
and
resistors,
so
so
water
tank
heaters,
you
know,
like
the
electric
water
tanks,
it's
a
low-cost
way
to
do
it.
The
heater
element
costs
like
five
bucks
for
like
three
kilowatts
or
five
kilowatts
up
to
it's
like
a
dollar,
a
kilowatt.
How
do
you
do
it
to
be
any?
I
mean
it's
kind
of
wasteful,
but
if
you
have
a
lot
of
pv,
that's
one
way
to
do
it.
A
It's
not
water
tank!
It's
water,
heater,
water,
heater
element!
These
things
only
cost
a
few
bucks,
but
if
you
get
one,
that's
240
volts
handles
a
lot
of
out
of
power.
They're
like
five
kilowatts,
easy
in
like
five
bucks,
very
cheap.
So
if
you
have
pv
or
in
emergencies,
if
you've
got
a
cold
day
and
you
really
need
to
heat
it
using
grid
electricity,
it's
gonna
cost
you
a
bit,
but
you
got
to
do
it's
like
heating,
a
house,
but
that
way
you
can
save
your
system,
so
what
I
would
do
actually.
A
Well,
you
need
you
need
to.
You
definitely
need
to
put
it
put
some
kind
of
a
shroud,
so
it
doesn't
touch
the
sides,
but
just
make
a
submersion
heater
element.
How
you
do
it.
You
connect
two
regular
wires
put
a
tube
around
it.
Pour
potting
compound
in
there
to
make
it
airtight
watertight
seal
on
that
on
that
end,
so
you
got
a
dangling
thing
on
two
wires
which
are
already
insulated
and
you
got
potting
compound
the
same
stuff.
They
use
to
seal
up.
Electronics,
like
you
see
some
electronics
that
have
this
black.
A
So
we
have.
We
have
done
that,
for
example,
in
a
hydronic
stove
in
jeff's
house,
we
have
one
of
these
sticking
into
the
stove
for
when
you're
not
running
the
stove
in
the
winter.
If
you
want
to
walk
away,
you
can
just
turn
that
on
to
keep
keep
the
water
hot.
I
actually
did
do
this.
I
put
this
an
element
just
like
this
submerged
it.
A
What
I
did
there
was
actually
do
a
long
pvc
pipe.
So
I
didn't
use
potting
compound
since
I
didn't
have
it
on
hand.
So
I
just
put
this
long
tube
and
just
caulk
up
or
like
whatever
I
used
there.
I
forget
what
I
used
so
the
heater
element
the
wires
were
going
in
there.
No
water
was
in
there.
I
just
ran
that
ran
that
for
some
time
for
heating
actually
of
the
pv
panels
on
the
faculty
house,
there's
pv
panels
up
there.
A
We
just
ran
a
wire
from
there
to
the
heater
it
works,
but
I
mean
yeah
for
that.
That
example,
like
water
gets
in
there
you'll
get
short
circuits.
So
it's
not
good,
but
yeah.
You
can
do
this.
You
can
do
this
as
an
easy
way
or
thermal
like
solar
thermal,
but
for
solar
thermal
yeah.
You
have
to
prove
you
know.
There
are
solar,
like
pretty
cool,
like
solar
thermal
evacuated
tubes.
Does
it.
A
A
So,
like
string,
inverters
high
power,
pv
systems
string
up
a
bunch
of
your
panels.
Each
of
them
are
like
30
volts.
The
safe
voltage
for
house
wiring
is
about
600,
so
you
string
up
20
of
them
and
then
do
like
like
two
or
three
three
of
these
heater
elements.
So
240
times
three
720
and
you're
running
like
the
600
volt
dc
from
your
panels,
like
that's
like
such
a
simple
thing
to
do
like
no
power,
electronics
involved
it
just
whatever
power
the
the
pvs
have
that's
what
gets
put
into
the
water.
A
A
It's
already
threaded
there,
so
you
can
say
3d
print,
so
here
yeah
he
would
be
the
best
thing,
like
3d
print,
a
fitting
screw
that
into
a
little
fitting,
with
with
a
lip
on
it,
pour
your
potting
compound
in
there
and
then
you
have
your
watertight
heater
element
like
that,
and
you
can
even
3d
print
like
a
little
shrouds.
It's
you
know
a
bunch
of
holes
in
it
so
that
when
you
submerge
it
it
doesn't
hit
the
sides.
So
you
don't
melt
anything
because
it'll
be
hot
around
it.
A
The
only
thing
you
got
to
worry
about
is
in
regular
water.
You
get
buildup
of
like
algae
or
whatever.
If
it's
not
running,
or
it's
kind
of,
because
it's
a
high
temperature
thing,
it
tends
to
get
a
lot
of
settling
on
it,
so
you
kind
of
have
to
clean
it
every
once
in
a
while.
A
So
in
which
case,
if
you
talk
about
zero
maintenance,
you
know
that
wouldn't
do
you'd
have
to
clean
it
like
every
month
or
something.
But
if
you
wanted
zero
maintenance,
then
you
have
to
do
a
heat,
exchanger
route
so,
for
example,
as
simple
as
the
55
gallon
drum
wound,
with
100
or
200
feet
of
the
pecs.
A
That
was
our
heater
for
the
for
the
aquaponic
greenhouse
that
works.
Great,
I
mean
the
water
gets
all
the
heat
into
the
water
and
never
really
cleaned
it.
It
pretty
much.
That
was
good.
It's
a
heat,
exchanger
route,
where
the
fluid
medium
is
clean
all
the
time.
So
whatever
is
heating
like
if
you're
using
an
electric
heater
that
that
heater
element
never
gets
dirty
and
the
temperature
at
the
tv
at
the
packs
is
low
enough.
It's
it's
your
nice
hot
water
that
it
doesn't
tend
to
cause
a
lot
of
settling
of
things
on
it.
A
It's
all
you
know,
get
get
algae
growing
on
and
stuff
like
that,
but
that's
still
as
long
as
it's
very
wet
it
kind
of
still
conducts
the
heat
quite
well
so
like
in
a
whole
three,
three
years
or
four
years,
three
or
so
years
of
running
that
heater
in
there,
probably
three
or
four
years
yeah
I
mean
never
had
to
clean
or
anything
so
so
that
was
a
good
route,
the
very
simple
route
of
the
packs
heater
submerged
in
in
water.
So
that's
a
good
route.
A
Okay,
but
moving
on
to
so
use,
bug
screen
for
cracks
corners
have
like
eight
screws
in
it.
Corners
have
eight
screws
minimum
for
the
pond.
We
have
to
make
sure
that
those
those
reinforcing
bars
the
the
wood
bars
that
we
put
in
with
concrete
nails.
They
just
stay,
but
I
think
that's
a
pretty
decent
connection.
We
want
to
make
sure
that
the
corners
are
buttoned
up
and
we're
ready
for
the
polyethylene
and
then
we're
not
puncturing
that
thing
anywhere
on
the
bottom.
A
It's
like
it's
immersion
heaters,
immersion
heaters,
immersion
pumps,
you
don't
have
to
have
a
bung
or
something
at
the
bottom,
which
is
a
leak
point.
What
do
you
do
so?
Yeah
polyethylene
there's
a
tr
a
way
you
can
fold
the
corners
so
that
they
get
very
neat
like
as
opposed
to.
A
Like
you
can
crumple
up
the
polyethylene
and
make
like
this
this
funky
corner,
but
there's
a
way
you
can
fold
it
in
a
very
neat
way
that
it's
completely
square.
So
we
can
do
that.
This
is
just
a
pattern
you
have
to
follow.
So
that's
there's
some
tr,
let's
see
if
we
can
find
it
so
like
how
to
fold
a
square
corner.
A
Kind
of
like
that,
it's
like
origami,
so
how
to
do
a
square
corner
with
poly
ethylene.
A
A
A
I
mean
you
can
do
that
kind
of
stuff
where
you're
using
glues
and
stuff
like
that.
But
you
can
make
a
fold,
that's
completely
waterproof
up
to
the
very
top,
and
so,
but
no
it's
a
little
different
than
this.
We'll
just
do
that
in
practice,
so
corners.
So
then
pond
liner,
which
is
just
polyethylene
poly
pond
liner,
barn,
pole,
barn
screws.
So
let's.
A
F
A
Like
18
inches,
no
less,
no,
no
more
than
that,
like
I
see
a
places
where
it's
like,
like
this
kind
of
distance,
do
it
a
little
more
tight
because
you
want
to
keep
that
on
not
coming
off,
also
for
like
air
infiltration
and
all
these
little
cracks
add
up
like
an
average
house
has
like
a
apparently
like
a
window-sized
crack
happening
at
all
times.
A
However,
however
much
but
yeah
there's
like
little
gaps,
they
add
up
and
air
can
get
into
anything.
If
you
have
a
high
wind,
you'll
notice,
we
actually
do
notice
that
on
a
cd
go
home
on
very
windy
days,
it's
it's
actually
much
cooler
inside
because
there
must
be
enough
cracks,
and
one
of
the
main
challenges
for
the
penalized
construction
is.
Is
the
good
tight
fit
between
the
panels?
A
You
have
to
do
that
kind
of
stuff,
otherwise
you're
going
to
get
all
these
holes
and
it's
it's
like
not
not
going
to
be
bad
in,
like
warm
climates,
but
if
you're
really
paying
attention
to
zero
energy
homes
and
and
high
level
of
of
thermal
insulation
that
really
matters,
and
so,
if
you're
like
in
a
windy
area
like
the
house
we
built,
you
know
if
you
got
wind
all
the
time
and
super
cold,
it's
it's
gonna
get
expensive
in
the
winter.
C
A
It
so
that's
just
a
consideration,
it's
important
so,
for
example
like
the
screws,
every
18
inches.
At
least
I
mean,
if
you
think
about
it,
like
that
batten
can
kind
of
like
bend
up
a
little
bit.
So
it's
like
more
like
even
every
foot
you'd
want
it
and
actually
in
real
conditions.
A
We
would
do
six
inches
on
the
edge
for
for
the
long
term,
so
we
don't
get
any
broken
screws
that
come
from
this
thing,
flapping
in
a
wind,
the
screws
down
the
middle
is
basically
for
flapping,
with
the
wind
and
and
over
time.
A
If
you
have
enough
of
that,
flapping
like
even
the
edges,
are
going
to
come
out,
they're
going
to
just
start
breaking
from
from
the
wood.
So
you
need
that
metal.
I
think
that's
the
main
points
for
quality
control.
So,
let's
talk
about
systems,
then
we
want
to
build.
A
Let's
go
to
aquapon
well,
where
are
we
going
to
so
so
the?
Where
are
we
going
to
aquaponic
greenhouse
and
there's
a
bunch
of
documents
on
all
the
mechanical
subsystems?
So
I'm
gonna
just
put
a
link
aquaponic
greenhouse.
A
A
And
that's
that's
the
idea.
We've
got
a
bunch
of
these
already
prepared.
We've
got.
We've
got
a
detailed
instruction
for
how
to
do
it.
What
goes
inside
is
this
two
by
four
piece
of
it's
called
reticulated
foam.
A
So
here
the
build
instructions
and
it's
detailed.
It's
got
bills
and
materials
like
where
you
get
this
stuff.
So
you
start
with
4x10
pvc
pipe.
If
you're
more
eco,
you
can
go
to
polyethylene
pipe.
If
you
don't
like
pvc,
which
will
be
twice
as
expensive,
but
you
get
just
regular,
solid
core,
solid
pvc
sewer
drain
pipe
like
this
four
feet,
four
inch
by
ten,
so
we're
using
just
four
inches.
That's
plenty
of
room
like
how
big
for
the
pipe
I
mean,
six
inches.
A
Four
inches
four
inches
is
enough
for
the
roots
like
the
root
mass
is
like
a
nice
ball.
You
want
the
main
consideration.
There
would
be,
I
think,
weight
because
once
you
get
that
whole
reticulated,
foam,
wet
with
water
and
you've
got
six
inches
like
four
inches
is
quite
convenient,
because
then
the
towers
are
light
enough.
So
you
can
still
carry
them
like
you
can
easily
say
you
want
to
replace
a
tower
say.
A
Your
planting
system
involves
where
you
take
the
tower
and
put
it
to
your
work
table
and
you
actually
plant
it
conveniently
so
you're
not
leaning
over
the
pond
and
falling
in
there
or
whatever.
A
So
these
are
designed
to
be
light
enough
to
be
carried
by
a
single
person,
so
you
can
just
take
it
off
the
hook
and
go
to
your
workstation
if
you
want
to,
but
but
I
guess,
we'd
want
to
set
up
the
greenhouse
where
you've
got
automated
planting
with
our
auto,
auto
seeder,
and
then
you
take
a
tray.
Take
one
tray
put
in
those
deep
pots
into
the
the
holes
which,
as
I
mentioned
the
other
day,
the
deep
pots
happened
to
fit
in
the
same
holes.
A
That
was
kind
of
an
accident
because
we
did
the
nuts
and
we
had
all
these
pots,
and
we
said
hey.
Why
not
just
grow
these
things
like
the
nuts
which
you
do
100
trays
for
mass
production
right,
so
here,
you're
talking
mass
production,
you've
got
this
one
tray.
It's
got
100
deep
pots
that
your
farmbot
automated
system
farmbot
slash
universal
access
farm
about
it's
called
farmbot
based
universal
access
cedar.
So
it's
called
the
universal
access
cedar.
You
got
this
all
planted
automatically.
A
You
take
that
so
zero
time
on
your
side,
except
of
putting
seeds
into
the
seed
trays
of
the
cedar.
So
now
you
take
that
into
the
towers
and
every
few
seconds
you're
feeding,
you're,
taking
out
an
old
one.
If
you
harvested
it
so
say
you
harvested,
then
you
want
to
replant
everything
is
out
of
the
tower.
You
got
the
black.
The
holes
insert
the
deep
pots
in
there.
So
there's
the
d-pods
that
actually
work.
A
A
A
Yeah,
let's
let's
go
to
the
pic
in
our
in
our
dock-
this
would
be
I'll,
show
you
some
pictures
at
least
or
in
the
video.
No,
that
was
kind
of
a
thing
we
stumbled
upon.
So
here
you
see
the
the
regular
towers.
You
see
things
growing
in
there.
You
can
basically
put
the
plant,
but
you
want
to
keep
the
root
mass
in
some
kind
of
a
little
net
pot,
they're
called
net
pots.
So
you
saw
the
net
pots
here
the
other
day.
I
A
Yeah
I
mean
yeah,
but
now
the
the
roots
they
can
go
through
the
entire
reticulated
foam
medium.
They
can
go
if
you
have
the
tower
even
in
water,
they'll
be
in
water.
So
if
you
have
plants
that
don't
mind
water
watered
roots
like,
for
example,
watercress
you're
gonna
have
like
the
bottom
with
watercress.
That's
the
roots
are
going
all
over
the
pond
and
stuff
like
that
too.
So
yeah,
which.
A
A
A
Well,
if
it's
that
much
okay
well,
if
you
have
that
much
and
you've
got
perlite
or
other
growth
medium,
a
lot
of
the
root
will
be
that's
a
lot.
A
lot
of
the
root
will
already
be
there.
So
if
you
have
like
a
lettuce,
that's
just
you
know
a
baby
one
like
that.
Most
of
the
roots
will
be
there.
Even
if
you
damage
it,
hey,
that's
fine,
they'll
regrow,
the
roots,
so
yeah
the
roots
will
come
out
those
bottom
holes
and
you
can
get
this
huge.
You
can
cut
it.
A
You
can
do
whatever
I'm
just
saying
like
you
can
actually
take
your
because
the
towers
are
human
sized.
You
got
your
van,
you
get
a
white
van
and
you
hang
those
towers
in
the
back
and
you
take
and
mark
it
that
way,
and
you
have
a
show
at
market
right
so
that
that's
another
way
to
do
it.
I
mean
the
potential
here
is
like
with
this.
Modularity
is
crazy.
I
mean
this.
I'm
saying
this
is
this
revenue
model
on
on
this
little
puppy
here
is:
is.
A
A
Course,
and
that
will
be
your
your
second
product,
offering
at
your
booth,
here's
training
for
how
to
do
it.
A
So
it's
the
same,
so
we
planted
out
the
the
nuts
into
these
little
holes.
We
took
the
nuts
and
plant
them
here
same
pots
same
little
pots
and
those
pots
could
actually
come
in,
like
there's
a
six
inch
version
and
like
a
nine
inch
version,
so
you
can
do
both
the
small
ones
actually
fit
right
well
within
the
holes,
but
otherwise
you've
got
things
like.
A
What's
that
in
there
that's
a
little
net
pot.
So
it's
just
a
little
3d
printed
net
pot,
which
you
can
hardly
see
there,
but
so
how
does
this
system
look
so
in
places
like,
for
example,
so
that's
basil,
like
basil
and
mint,
are
going
to
take
over
your
greenhouse
basil.
You
can
take
it
off
shoot
because
that
grows
root.
It's
vegetatively
propagated.
You
can
just
take
an
offshoot,
that's
mint
or
basil.
A
G
A
That
would
turn
it
into
aeroponic,
so
yeah
you
could
have
like
a
tube.
No,
the
holes
would
have
to
be
plugged
up
otherwise.
A
F
Each
well
they're
inside
the
net
pots,
though
right
there
should
be
enough
structure,
but
I
think
the
the
foam
is
to
transfer
the
water
to
the
ends
of
the
ones
because
otherwise
it
just
shifts
in
the
middle.
It
never
hits
anything
exactly
because
I
know
I
built
one
for
the
hydroponics
and
I
had
to
go
like
a
little
knit
so
that
it
rains
on
the
sides,
because
otherwise
it
won't
reach
a
point.
A
It's
sponge
sponge
material.
It's
like
some
polyurethane
thing
and,
as
I
mentioned,
worms
started
living
in
that
foam
too.
How
I
mean
they
got
somewhere,
they
got
seeded
in
there,
but
so
does
that
clarify
the
the
pot
directly
in
yeah.
C
I
C
A
A
So
there's
all
these
docks.
We
have-
we
have
a
bunch
of
stuff
on
this
because
the
net
had
this
there's
this
one,
the
greenhouse
nursery
module.
So
so
this
is
actually
talking
more
about
what
I
was
talking
about
the
other
day
with
respect
to
the
all
the
shelves,
but
here
actually
so,
let's
actually
look
at
this.
This
page
here.
A
So,
like
all
the
builds,
that's,
let's
do.
A
So
so
go
to
aquaponic
greenhouse
go
to
the
towers.
So,
let's
nail
the
towers
like
what's
all
required
for
that,
we
have
a
bunch
of
them
that
we
can
just
pretty
much
hang
up
and
what
does
that
mean
so
screws
the
three-inch
screws
work?
Well,
they're
I
mean
they
can
hold
like
a
hundred
pounds
each
easily
so
aqua,
let's
just
go
through
the
dock
of
how
we
build
build
the
g
towers
first.
So
we'll
hang
them.
If
you
guys
want,
we
can
take
some
four
inch
pipes
do
the
markings.
A
No,
not
here
they're
they're
in
this
dock
right
here,
let's
I
mean,
let's
take
a
look
at
some
pictures
for
for
what
this
looks
like
in
practice.
So
what
you'll
do
is
take
these
tubes,
so.
C
G
A
So
we
basically
take
mark
lines
so
there's
about,
like
a
70
degree
angle
between
the
two
rows
of
of
the
holes.
You
mark
a
slit
cut
it
with
a
circular
circular
saw
no
cut
off,
saw
it's
a
small
slit,
you're
cutting
an
edge
of
it,
take
a
heat
gun
which
means
like
heat
guns
and
plastic.
They
totally
make
plastic
completely
pliable
to
do
whatever
you
want.
A
K
C
A
You
see
those
slits
there
yeah,
I
mean
pretty
simple,
like
the
the
bottle,
you
draw
those
two
lines
and
re
remount,
the
the
slits
that
you
cut
with
with
the
bottle.
Oh
you
see
this.
One
actually
has
three
sides.
We
typically
yeah.
We
did
both
versions
where
it's
like,
I
think,
two
or
three
sides
I
think
most
of
them.
A
It's
actually
a
interesting
addition,
because
then
you're
actually
tapping
the
full
full
volume
that
you
can
handle
with
this,
because
the
backside,
if
you
give
it
more
light,
yeah
you're,
definitely
going
to
get
more
productivity
and
the
plants
are
not
limited
by
the
amount
of
light
they
have
it's
well,
they
are.
Let's
see.
A
Light
is
important
in
in
this
climate.
Here
the
the
temperature
is
even
more
important,
but
yes,
if
you
do
rotate,
this
that'll
be
an
interesting
system.
So
that
would
be
a
case
for
some.
Maybe
some
kind
of
a
simple
hydraulic
motor,
a
water
run
motor,
that's
3d
printed
that
lasts
forever.
It
doesn't
decompose
like
metals,
so
a
simple
hydraulic
motor,
that's
actually
pumped
by
the
same
pumping
system
that
you've
got
pumping
through
this.
You
could
do
that.
I
mean
you
can
do
a
like
those
sprayer
pumps.
They
have
enough
pressure.
A
A
You
can
do
this
not
too
much
sweat
on
that.
I
have
never
done
it
done
this,
but
they've
got
various
designs.
These
are
typically
like
ones
like
this
are
veins,
which
would
spin
very
fast,
but
you
also
have
the
ability
to
print
helical
gears
very
effectively
with
3d
printing,
so
you
put
a
little
gear
down
on
it
and
there
you've
got
your
nice
little
rotor
cost
you
30
cents
in
materials.
A
A
The
question
is
how
good
your
design
is
and
how
efficient
it
is,
but
you
can
definitely
do
it,
and
this
is
a
case
once
again,
where
you'll
find
probably
like
a
lot
of
poor
designs
and
some
that
might
be
really
good,
or
maybe
none
that
are
really
good,
because
actually,
when
you
do
make
it
really
good
typically
disappears
from
the
open
source.
So
that's
kind
of
the
typical
thing
that
happens
so
so
you
get
a
bunch
of
you're,
you're,
selecting
for
inferior
product
and,
unfortunately,
that's
a
negative
side
of
open
source.
A
It
kind
of
selects
well,
but
that's,
not
true,
open
source
because
that's
like
actually
the
opposite
of
open
source
where
people
are
not
sharing
the
improvement,
so
it's
so
actually
open
source.
True,
open
source
means
that
the
best
best
things
emerge
does
not
happen
a
lot.
That's
that's
a
weakness
of
the
open
source
hardware
model
at
this
point,
at
least
that
anytime,
anybody
gets
something
really
good.
They
close
it
up.
So
that's
a
challenge
to
overcome
as
far
as
the
specific
instructions
for
this.
So
let's,
let's
just
continue
on
this.
B
You're
saying
if
you
could
provide
supplemental
lighting
or
whatever
it
would
be
possible
to
run
a
parallel
hole
on
the
other
side
of
each
of
the
ones
that
are
there
now,
if
you're
able
to
move
against
me.
A
Yeah
so
you're
like
up
to
doubling
your
capacity
if
you're
growing
in
a
back
side,
because
the
backside
is
what
doesn't
get
a
lot
of
sun
might
be
in
the
shade,
but
if
you
just
give
it
enough,
give
that
extra,
20,
30
percent
or
something
it
might
just
be
enough
to
get
it
to
its
like
full
growth,
potential
and
stuff
like
that,
because
typically
you'll
see
like
the
things
in
the
shade
they're
going
to
get
like
weak
and
lanky
and
stuff
like
that,
so
they'll
definitely
need
more
sun.
A
So
I
mean
the
full
instructional
is
here
like
for
people
who
want
to
make
make
this
reticulated
your
urethane
foam.
There's
the
source
right
there
hipkoplasticshipco.com
it's
all
there,
they're
two
by
three
and
a
half
inch
by
three
foot
pieces:
okay,
so
actually
the
towers
we're
making.
A
It
appears
they're
more,
like
three
foot
long
pieces.
Well,
did
we
do
three?
I
thought
we
did
five
feet.
Maybe
they're
just
three
foot
sections
so
that
water
resistant
deck
screws
deck
screws
are
typically
exterior
rated.
You
need
some
hanger
wire
because
you
got
to
hang
these
things
on
a
nail.
So
hanger
wire
is
something
like
this
just
something
that's
coated
like
maybe
a
hanger
wire,
which
is
just
heavy
wire
that
you
can
hang
the
towers
on.
You
can
do
like
fence
wire
as
well.
I
use
fence
wire.
A
A
So
yeah
we're
doing
the
two
two
columns.
Like
the
picture.
You
saw
there
that
was
like
three
slots,
but
we
kind
of
ended
up
with
two,
because
that's
the
light
limits
on
the
back
side.
So.
A
So
you're
marking
you,
you
draw
two
vertical
lines
just
marks.
I
don't
know
where
that
drill
bit
comes
in,
but
all
we're
doing
is
miter
saw
on
that
slit
line.
Yeah.
Oh,
I
see
the
eighth
inch
hole
for
the
hanger
wire.
That's
you
just
hanging
that,
but
to
cut
it
to
cut
those
slits,
it's
just
a
miter
saw
along
the
nice
marks
like.
A
So
that's
that's
the
growing
towers
we
can
can
make
some.
We
also
have
have
a
bunch
that
are
already
prepared
that
we
can
just
hang
up
so
okay
beds,
gutters
shelves,
worms,
mushrooms,
build
what
else
is
required
to
make
this
the
growing
towers
work,
so
you
want
a
pump
system.
So
let's
look
at
some
of
the
components
that
we
have
to
make
it
work
so
the
workhorse
there
would
be
something
like
this:
that's
we
got
a
couple
of
these
pumps.
That's
just
the
standard,
submersible
water
pump.
It's
like
27
bucks.
A
It's
got
like
10
feet
of
head
max
head
99.7
feet,
so
the
consideration
there
is,
you
want
to
make
sure
it
pumps
all
the
way
to
the
top
of
the
tower.
Now,
if
you
hang
it
at
the
very
top
of
the
pond,
then
you've
got
about
five
four
feet
to
go,
so
this
would
be
plenty
for
what
we're
doing
right
now
and
just
one
practical
constraint
is
like
don't
put
at
the
very
bottom
in
case
you
have
some
accident
where
a
pipe
disconnects
and
you
leak
out
your
entire
pond.
A
So
put
it
hang
it
so
it
hangs.
It
can.
Hang
by
whatever
you're
attaching
to
like
whatever
polyethylene
pipe
you're,
attaching
to
the
top
so
suspend
it
towards
the
top.
So
if
you
have
an
accident,
you're
only
sucking
out
a
known
amount
of
water
and
don't
kill
your
system.
So
that's
that's
a
consideration.
A
So
we've
got
we're.
Gonna
have
the
two
by
four
two
by
six
board
on
the
top.
Hang
it
off
of
that,
because
the
fit
the
pipe
goes
all
the
way
to
the
top
and
into
all
the
towers.
Just
hang
it
from
you
know,
use
some
wire
or
some
attach
it
to
the
to
the
ceiling
and
hang
it
so
yeah,
maybe
from
the
rebar
or
yeah.
If
we're
gonna
have
the
rebar
across
which
we
actually
didn't
then
say
here
on
the
qc
part.
A
Oh
yeah,
so
do
the
rebar
support
across
it
could
be
like
a
board.
We
can
just
do
a
board.
The
disadvantage
of
a
board
is,
if
you
have
you
know
it
takes
more
space,
so
rebar,
I
think
half
inch
rebar,
that's
a
easy
way
to
do
it
or
we
can
just
put
up
a
board
right
across
the
middle.
I
mean
we
can
do
that
too,
and
then
spill
make
sure
you're
not
spilling
onto
that
board
because
then
we'll
start
leaking
over
the
edge
just
put
make
sure
the
towers
are
on
either
side
of
the
board.
A
That's
all
so
I
mean
reinforcement
down
the
middle.
A
A
So
yeah
supported
like
this.
If
you
do
do
a
board,
just
do
that
and
you
can
screw
it
directly
into
the
you
know,
what's
below
it,
but
you'd,
actually,
because
I
mentioned
those
edge
on
because,
if
you're
screwing
into
what's
below
that,
that
would
be
the
edge
of
the
board
below
that
it's
typically
a
weak
connection.
A
So
you
want
to
reinforce
that
by
how,
by
maybe
putting
I
don't
know,
some
pipe
hanger
strap
just
something
just
kind
of
got
to
pay
attention
that
that
that's
a
solid
connection
or
a
piece
of
metal
that
you
screw
into
like
across
both.
So
that's
not
coming
out
it's
going
into
the
perpendicular
to
the
grain,
so,
but
a
little
reinforcement
would
help
there.
A
A
A
All
right
step
number
one
make
or
hang
existing
ones.
A
Okay,
so
how
do
you
hang
it?
So,
let's
find
a
board.
I
know
we
have
some
two
by
two
by
eight
two
by
fours.
We
can
just
use
use
that,
for
now
we
mentioned
that
the
ones
in
the
first
aquaponic
green
has
they
all
bent
up,
but
they
were
also
on
four
foot
centers.
Here
we
have
two
foot
centers,
so
actually
two
by
four
won't
be
too
bad
here,
we'll
be
okay
for
now.
A
H
C
A
A
So
you
kind
of
want
to
be
careful
with
that's
where
actually
the
flat
printed
plastics
would
actually
be
an
advantage,
because
all
those
chemicals
are
going
to
leach
out
of
that
and
if
you're
eating
your
fish
you're
going
to
be
eating
the
preservative
in
the
wood,
so
we
just
took
the
wood
and
painted
it,
but
you
saw
it.
It
was
it's
starting
to
crumble,
that
wood
down
there.
So
that's
where
the
3d
printed,
lumber
or
plastic
lumber
would
actually
be
a
great
case
for
use
using
it.
A
So
I
hang
a
2x4
treated.
You
have
to
consider
that
I
mean
those
chemicals
and
food
systems
are
not
not
so
compatible,
so
just
be
aware
of
that.
So
you're
not
eating
directly
of
things
that
have
been
eating
off
your
wood.
Like
don't,
grow
your
mushrooms,
untreated
wood.
They
probably
they
won't
grow
because
it's
fungicidal
so
but.
C
A
I'm
I'm
not
sure
about
that,
not
sure
about
that.
But
if
you
want
to
have
the
organic
version,
then
you
use
rot
resistant
wood
like
cedar
or
black
locust
or
other
species
like
the
jungle,
has
a
lot
of
rot
resistant
stuff
right.
C
A
So
so
there's
the
pond.
Let's
say
we
got
the
pump
in
there
and
we
want
to
do
two
pumps
just
just
as
an
experiment
in
resiliency,
so
we
can
control
these
like.
If
one
fails,
we
can
have
the
other
this
just
just
to
show
or
we
just
do
one
if
we
don't
have
time,
but
so
then
you
got
so.
You
got
your
treated
2x4
hanging
off
the
top
all
the
way
across
where
the
pond
is
so.
A
A
No
because
the
spacing
would
be
that,
because
the
lettuce
grows
on
this
side
and
the
other
side,
no,
we
believe
so
that
make
the
sizing
that
equivalent
to
the
product
you
want
to
grow
if
it's
kale
it'd
be
like
huge,
but
yeah
do
do
like
12
inches
like
how
big
is
your
head
of
lettuce
get
about
12
inches?
We
only
have
well,
actually
that's
quite
good.
That
means
10
to
the
length
it's
perfect
and
then
do
two
rows.
A
I
mean
that
thing
could
actually
fit
like
three
rows,
but
maybe
do
like
two
that
are
easily
accessible,
20
towers
in
that
20
towers
times,
20
plants,
22
440
plants
in
a
little
area,
so
60
square
feet
for
440
plants
6
times
10.
That's
quite
good,
like.
A
A
A
So
you
got
your
wire
and
I
think
the
some
wires
actually
may
be
on
those
those
towers
already.
So
you
got
your
tower,
it's
like
that.
So
what
questions
do
we
have?
We
have
one
five
foot
section:
that's
all
that
will
fit
in
there,
so
the
five
foot
section
will
pretty
much
be
on
the
top
of
the
top
of
the
pond,
because
it's
the
pond
is
about
three
feet
so
be
just
five.
Five
feet
will
be
just
perfect
for
that.
A
If
you
want
to
get
a
little
more
space,
I
mean
well
actually,
oh
well,
we
have
hanging
locations
every
two
feet
which
are
the
joists,
so
you
can
also
use
that
to
hang
things,
but
if
you
want
it
to
be
nine
in,
you
know
12
inch
spacing.
Then
you
got
to
hang
a
bar
like
this,
so
20
towers.
A
A
5
foot
5
foot
length
and
then
so
we
gotta
attach
the
the
pumping
to
it.
So
we
can
yeah,
maybe
let's
not
get
in,
let's
go,
let's
go
into
the
the
bigger
things
which
would
be
like
growing
beds
and
growing
growing
shelves.
A
K
Why
are
we
doing
two
by
fours
lumber
because
they
were
bending
in
the
other?
Do
we
now
want
to
try
two
by
six.
A
K
C
Okay,
okay,
yeah
they're.
A
Eight
feet
right
do
one
is
which
is
eight
feet,
and
that
gets
you
right
to
the
edge.
You
know
a
foot
from
the
edges.
I
guess
you
gotta,
I
mean
or
make
the
spaces
most
of
them
are
just
the
one
two
rows.
So
do
20
towers,
two
rows:
yeah
yeah,
two
rows
of
ten
towers.
A
So
you
got
your
joists
here
that
are
supporting
that
every
two
feet,
so
so
your
eight
footer
will
end
up
actually
right
on
the
joists
and
then
you'll
have
three
more
in
between
so
every
two
feet.
That's
that's
your
choice.
That's
kind
of
joyce
pattern
for
the
roof,
but
you
attach
the
2x4
to
the
bottom
of
the
joists,
with
screws.
A
What
else
do
we
need
to
know
to
to
succeed
at
this?
What's
the
spacing
between
them,
it's
convenient,
so
you
can
reach
them
easily,
so
you
don't
have
to
be
bending
over
the
pond
too
much,
which
would
actually
make
a
case
for
like
one
or
two
more
like.
Actually,
the
pattern
that
would
be
most
convenient
would
actually
be.
A
So,
like
even
put
once
like,
where
the
dot
is
like
right,
there
so
add
like
two
more
towers,
not
not
a
big
deal,
but
just
maybe
just
do
the
two
rows,
but
you
do
have
access
when
you
think
about
it.
Six
feet
is
quite
a
bit,
so
the
spacing
between
them-
yeah,
I
mean
put
them
like.
Maybe
one
foot
in
so
you
got
four
foot
spacing
between
them.
A
H
A
A
Screw
in
a
fitting
one,
half
inch
npt
fitting
and
half
inch
packs
or
poly
back
to
the
tank,
so
you
can
fill
this
entire
greenhouse
with
it.
That
would
be
one
operation
you
can
do.
Okay,
I
want
to
just
optimize
for
the
number
of
towers,
how
many?
How
many
can
you
fit
like
a
hundred?
No,
not
a
hundred,
maybe
like
40.
A
twice
as
many
about
maybe
three
times
as
many
I
mean
you
can
line
well,
what
is
what
is
that?
What's
the
theoretical
limit
there
like?
If
you
go
so
say
you
got
your
entire
square
filled
with
towers.
What's
a
good
distance
between
towers,
it's
like
four
feet
before
that.
After
that
you
get
like
a
lot
of
a
lot
of
shading
we're
not
talking
about
auxiliary
lighting.
A
A
A
So
you
basically
get
the
ones
on
the
edges
like
right
up
to
the
walls.
Now,
if
you've
got
summer,
why
don't
you
do
this
here
off
the
same
pond?
A
C
I
Like
what's
the
maximum
quantity
which
we
can
like
irrigate
like
how
many
plants
can
we
irrigate
with
one
pond
right.
A
And
that
was
plenty
of
nutrients.
We
didn't
do
any
supplemental
feeding
for
that.
That
was
all
the
aquaponic
water,
so
okay,
so
let's
take
that's
3,
000
gallons
to
ten
thousand
plants.
So
let's
take
we've
got
about
one
thousand
gallons
here,
so
we
can
do
like
three
thousand
plants.
A
A
H
A
They're
flourishing,
so
we
know
it,
we
know
it
can
be
done.
Look
at
the
bottom
detail.
So
what
happens
at
the
bottom
drip
detail?
So
this
is
like
kind
of
what
happens
if
you,
this
is
like
not
taken
care
of.
That's
like
purslane,
that's
a
weed,
let's
start
growing
in
it,
but
it'll
get
all
moldy
and
slimy
on
you.
If
you
don't
take
care
of
it.
What
happens
at
the
bottom?
A
That's
because
that
that's
actually
part
because
of
the
some
of
the
issues
where,
if
you
get
too
much
root,
mass
it'll
just
start
flowing
out
the
holes,
the
roots
get
so
packed
in
there,
like,
especially
like
mint
mint
just
takes
over,
but
if
you
had
yeah.
So
if
you
don't
take
care
of
it,
if
you
don't
harvest
and
then
let
it
regenerate
you'll
get
this,
the
water
will
just
spill
and
then
you
get
all
all
slime
and
algae
growing
everywhere,
which
is
fine,
that's
still
fish
food.
A
It
doesn't
look
nice
what
happens
to
the
water,
the
water
dribbles
down
the
bottom.
So
what
happens
when
you
cap
it
so
cap,
let's
say
tower
cap
detail
and
you
can
make
this.
We
haven't
done
this.
We
just
typically
ran
straight
to
the
the
ponds
because
we
didn't
need
more
space
tower
bottom
cap,
so
you
have
this
system,
I
mean
the
question
is:
what's
a
practical
distance
that
you
can
now
feed
your
assist
like
how
much?
A
A
You
know
I
mean
has
to
go
by
gravity
because
it's
only
gravity
feed,
so
whatever
you're
putting
down
there
has
to
be
at
a
lower
point.
So
it's
effectively
how
much
drain
you
know.
If
you
attach
it
somewhere
to
some
structure,
you
can
get
a
nice
slope
that
it
won't
won't
back
up
and
you
get
a
small
slope
like
a
quarter
inch
per
foot.
You
know
and.
A
There's
yeah,
if
you
cap,
that
at
the
bottom,
you're
going
to
have
at
least
a
little
bit
of
pressure
from
the
bottom
outside
of
what
starts
overflowing
out
of
the
first
hole
if
you're
in
a
plugged
condition
yeah.
So
if
you
plug
this
up,
you'll
see
water
starting
to
come
out
of
your
first
hole
on
the
bottom
of
the
tower.
A
I
don't
know
like
like
another
greenhouse.
I
mean
it's
a
bunch
of
plumbing
there.
So
so,
if
you
have
a
bunch
of
towers,
you
don't
want
to
run
like
a
single
line
from
one.
What
you
would
do
is
you
t
them
into
one
another?
So
say
you
got
a
bunch
of
towers
like
this.
This
is
say
this
is
outside
and
the
tank
is
say
the
tank
is
like
that's
the
tank
back.
G
A
A
A
So
you
got
this
little
t
fitting
at
the
bottom,
so
you
get
a
multi
bunch
of
multiple
ones
and
then
you
need
to
run
only
one
line
to
this,
so
you
can
have
a
whole
field
of
these
in
one
line
limited
by
how
much
water
you're
pumping.
So
this
tank-
it's
like
I
don't
know
like
maybe
like
16
feet-
would
be
practical,
not
a
problem.
A
A
A
Are
they're
taken
up
and
you
want
that
reticulated
foam,
because
it's
got
a
lot
of
air
space
roots
want
air
they
breathe
now?
What?
If
so,
that's
like
16
feet?
What,
if
you
want
you
have
this
detached
greenhouse,
but
you
want
to
hang
a
couple
of
towers
in
your
in
your
in
your
living
room
completely
doable.
A
Well,
in
that
case,
what
I
would
do
is
if
that
distance
to
the
greenhouse
is
so
long
do
a
little
sump.
So
so
this
is
one
way.
This
is
a
gravity
tank
gravity
system.
A
Okay,
what
if
you
have
a
really
huge
distance
to
cover-
and
you
can't
do
it
by
gravity
to
say
it's
up-
your
house
is
uphill:
no,
where
the
the
house
would
have
to
pump
back
up
hill,
so
you
can
do
a
sump
here,
so
so,
instead
of
a
gravity
system
going
right
into
the
tank
like
on
the
ground
or
in
the
ground,
you
have
like
a
you
know.
Five
gallon
bucket.
A
A
These
things,
but
these
things
do
need
a
filter.
They
get
clogged
up.
These
are
you
know,
20
bucks.
Even
we
got
this
tiny
one
with
one
gallon
per
minute.
It's
not
a
lot.
You
got
these
these.
These
are
typically
high
pressure,
low
low
volume,
kind
of
pumps
like
couple
of
gallons,
four
gallons
per
minute.
Now
this
one
is
four
gallons
for
seventy
dollars
and
about
four
gallons
is
probably
like
what
what
you'll
have
from
one
of
our
pumps
here
like
this
one.
A
B
A
A
Yeah,
this
is
now
where
you
need
some
pressure,
say
you
gotta.
These
things
have
20
to
50
psi
or
100
psi.
That's
hype!
That's
pretty
high
pressure!
That's
enough
like
if
we
3d
print
hydraulic
motors
that
run
on
water
for
life
track.
Those
motors
have
to
be
much
bigger,
but
that's
another
idea
like
psi
for
hydraulics
on
a
tractor
are
2000.
A
What
that
means
is
that
with
a
3d
printed
pump
set
that
runs
at
100
psi,
you
need
to
pump
like
if
the
pumps
are
like
motors.
Are
this
big.
It
need
would
need
to
be
10
times
bigger,
but
it
would
work.
So
that's
a
3d
printed
drive
for
tractors.
There.
You
go
water
pressure
at
100
psi.
Does
that
that's
a
lot
of
force,
the
you
know
those
100
psi
50
psi.
You
can't
stop!
That
with
your
hand,
it's
a
lot
of
force
there
that
could
be
turned
into
mechanical
drive.
H
We
also
we
went
through
some
pictures
of
martian's
old
greenhouse
and
whenever
a
pump
fails
you'll
those
plants
will
start
to
wither
within
like
two
hours,
so
we
even
discussed
like
having
a
dual
system,
a
backup
in
case
it
gets
you
away
so
yeah.
A
So
definitely
for
3d
printed
like
so
that's
one
route,
the
other
route
is
just
a
simple
bilge
pump
like
a
bilge
pump.
What's
it
called
like
some,
it's
just
a
sump
pump,
that's
exactly
what
it
is.
Yeah
these
things
have
like
10,
15
20
feet
ahead,
so
you
throw
one
of
these
inside
a
five
gallon
bucket.
A
A
A
Right
there
in
your
five
gallon
bucket,
so
now
your
your
water
line
here
that
you're
now
dribbling
you're
connecting
that
up
and
just
dribbling
this
into
your
five
gallon
bucket.
That's
wherever
you
are,
you
can
have
on
your
windowsill.
You
have
a
little
bucket
underneath
and
you
connect
all
these
up
this
way
for
your
pumped
route.
So
this
requires
electricity
and
mechanical
pumping.
This
other
way
gravity
system.
A
It's
resistant
to
pump
failure.
You
just
have
possibility
of.
B
Okay,
richard
well,
assuming
you
you
know,
didn't,
have
the
ability
to
use
a
gravity
tank.
You
know
the
alignment
there
would
you
be
able
to.
You
know,
have
a
a
drain
system.
You
know
in
the
bottom
of
you
know,
let's
say
the
pond,
you
know
underneath
it
that
has
a
backflow
valve
on
it.
You
know
that
connects
to
some
type
of
yeah
and
just.
A
Yeah
here
by
the
gravity
system,
that
is
like
the
safe
route,
I
mean
that's
the
most
resilient
route.
The
next
route
is
in
your
tank.
You
put
a
fitting
at
the
bottom,
so
you
can
drop.
You
can
have
that
much
more
drop,
just
three
feet
more
drop
in
our
case,
but
then
you
you're
going
lower
or
in
a
case
where
the
tank
is
in
ground.
Then
you
have
more
more
room
even
because
you've
got
like
the
depth
of
the
tank.
A
A
This
rubber
thing,
which
by
the
way,
is
a
great
thing
to
3d
print.
You
stick
in
a
pvc
pipe
and
it
makes
a
very
tight
watertight
connection.
What
can
we
do
in
wood?
Can
we
put
one
of
these
in
wood
and
make
it
watertight?
No,
no.
A
Friction
fit
just
put
some
oil
on
it.
Soap
on
it
friction
fit
a
pvc
pipe
into
this
hole
which
expands
when
you
put
the
pipe
in
it
seals
against,
whatever
you
cut
the
hole
in.
A
A
You'd
have
to
seal
you'd
have
to
do
like
the
two-sided,
screw-on
fitting
to
get
the
fit
get
the
fit
against
the
polyethylene,
because
yeah,
if
you
have
a
container
of
some
sort,
that's
solid.
You
can
use
this,
but
once
we
have
our
polyethylene
tank,
how
do
you
put
a
bung
at
the
bottom?
That's
a
challenge!
That's
definitely
a
challenge
and
a
dangerous
failure
point
so
for
this,
which
reason
we're
not
puncturing
that
anywhere
we're
just
letting
it
dribble
up
the
top
and
have
submersible
pumps
in
there,
which
is
a
more
resilient.
A
What,
if
you
don't
want
to
use
a
submersible
pump,
you
can
still
use
external
pumps,
but
you
have
to
prime
them
if
you're
going
over
the
top
of
the
pond
priming
means
that
you
get
the
first
flow
against
gravity
because
it
has
to
go
outside
over
the
top.
If
you
don't
puncture
at
the
bottom,
so
in
any
other
pump
system,
you'd
have
to
have
the
prime
for
the
sump
pump.
You
can't,
prime,
that
that
has
to
be
submerged
for
one
of
these
high
pressure
pumps
once
you
prime
them,
they
pretty
much
stay
primed.
A
So
you
can
use
one
of
these
get
suck.
You
know,
get
the
suction
happening,
prime,
it
means
you
you're
just
running
it.
Maybe
you
have
to
have
a
valve
where
you
actually
pour
water
down
it.
If
it's
enough,
if
it
can't
prime
by
itself,
but
these
kinds
of
pumps,
they
say
they
self-prime
up
to
like
a
few
feet.
So
in
the
case
where
we
have
that
three-foot
distance,
this
probably
would
self-prime
would
have
a
good
chance
of
doing
it.
It
would
probably
have
those
specs
here,
like
first
control,
f
self
priming.
A
Self
priming
spray
pump.
So,
like
you
know,
if
you
look
at
that,
it
says.
A
No,
it
doesn't
vertical
suction
force
of
two
meters.
The
pump
has
a
self-priming
function
to
prevent
liquid
from
flowing
back.
It
could
be
installed
above
water
tank,
but
it
doesn't
really
tell
you
if
you
had
this
self
prime.
What
exactly
is
that
number?
That
would
be
a
relevant
number
and
they
will
tell
you
that,
typically,
maybe
in
another.
F
A
10
inches
only
so
that
could
still
work
for
for
us
if
we
mount
the
pump
outside
the
tank,
because
you
can't
submerge
these
mount
it
at
the
top
outside
the
tank
and
has
to
prime
over
the
edge.
That
would
do
it
if
you've
got
a
full
tank.
If
you
don't
have
a
full
tank,
because
you
lost
due
to
evaporation,
then
it
won't
prime
anymore
but
yeah.
So
that's
just
practical
considerations.
A
What
we
did
in
the
actual
this
system,
which
I
talked
about
yesterday,
so
this
this
is
what
I
talked
about.
The
watering
shelves
with
the
fittings
where
the
top
shelf
flows
into
the
middle
and
to
the
bottom.
We
use
the
sump
pump
in
that
case
and
we
made
it
flow.
A
We
just
divide
it
into
the
two
sides
and
they
would
eventually
dribble
down
back
into
the
the
same
tank,
but
that
was
a
case
of
the
the
sump
pump
and
it
had
plenty
of
head
to
do
that
kind
of
a
distance
which
was
at
the
bottom
of
the
pond,
so
four
feet,
plus
like
six
feet
at
the
top,
so
at
least
10
10
feet.
It
would
work
with
good
flow.
A
A
Designed
it
in
block
sky,
that's
another
online;
well,
maybe
they
they
moved.
Bloxcat
is
another
simple
designer:
it's
like
it's,
not
not
freecad,
but
it's
just
a
simple
designer
for
stl
files
for
printing
files.
So
that's
what
we
did
in
our
shelves
here.
A
How
do
you
design
this
thing
took
threads
of
one
part
from
like
this?
This
other
file
from
thread
libraries
put
it
onto
this
fitting.
I
just
combined
a
couple
of
parts
and
drew
this
up
anyway,
so
we
got
the
towers,
any
questions
on
towers.
Can
we
install
them
so
20,
20
of
them
hanging
by
hanger
wire,
we're
not
doing
the
caps
on
the
bottom?
That
was
advanced
theory.
A
World
drip
drip
them
right
into
the
pond,
which
is
the
most
convenient
easy
thing,
but
in
this
system
like
we
were
trying
to
get
to
the
the
final
count
of
the
number
what's
what's
possible
on
the
interior
since
setting
up
on
the
exterior,
like
you
know,
that's
like
setting
up
another
greenhouse
because
you
have
to
hang
these
towers
from
somewhere.
So
you
need
a
solid
structure.
That's
not
trivial
you're,
going
to
have
a
pretty
solid
structure
out
there.
So
it's
like
building
another
greenhouse,
almost
minus
the
glazing.
A
So
if
you
got
five,
two
five
sets
times
five
times.
16
feet
equals
like
80
feet
times
20.
A
Well,
it
depends
how
far
they're
going
like
if
they're
going
to
the
5
foot
by
gravity,
then
you're
actually
missing
out
a
lot
of
bottom
space,
you're
missing
out
that
three
feet
at
the
bottom
of
the
tank,
so
the
ones
in
the
back
so
say
the
tank
is.
If
the
tank
were
down
here
and
you
got
like
one
or
two,
these
are
every
four
feet,
so
you're
spanning
like
two
of
them
with
the
tank
itself.
A
The
other
ones
could
be
taller,
but
you'd
have
to
have
them
some
pumping.
So
if
you
just
reduce
yourself
to
oh
yeah
yeah,
so
these
are
five
foot
sections.
That's
only
11
plants
per,
so
I
forgot
there
was
22
plants
per
10
foot
section
on
how
many
sides
of
the
oh.
But
if
you
do
that,
then
yeah,
then
you
go
back
to
22.
A
If
you
have
a
means
to
rotate
them,
something
like
that
or
you
use
the
backside
just
to
start
things,
and
then
you
rotate
it
to
get
it
to
the
full
sun,
but
so
yeah.
In
theory,
you
can
do
up
still
up
to
like
22.,
so
rough
number
22
times
80
is
like
yeah
1700
plants
or
so,
and
this
that
you're
taking
to
market
of
this
little
module
so
to
develop
a
robust
business
model
around
this
as
the
building
block
and
think
about.
Okay,
now
we
scale
one
module
two
modules
yeah.
A
Plants
and
what
we
say
about
the
maximum
for
our
system,
based
on
a
nut
nut
breeding
results.
We
have
10
000
plants,
11
000
plants
for
3,
000
gallons,
so
we
got
like
3
000
plants,
so
we're
still
well
within,
like
we
can
double
this
and
still
support
in
non-intensive
culture,
double
this
and
still
support
all
the
plants
with
ample
nutrients.
A
C
B
I
A
A
Well,
separating
electrolyzers,
that's
the
easy
part!
Well,
you
can
get
as
long
as
you're
venting
stuff
you're,
never
building
up
pressure
that
just
all
goes
away
faster
than
you
generated.
So
that's,
okay,
yeah,
so
towers.
Any
any
questions
on
how
to
do
that.
A
A
So
in
this,
what
do
we
use?
We
use
one
of
these.
These
are
actually
all
hyperlinked.
So
that's
standard,
it's
20,
watts,
45
liters
per
minute.
That
supplies
like
four
or
six
air
stones
get
a
couple
of
them
in
there.
One
would
be
enough,
I
mean
initially
when
a
fish
are
young,
you
just
need
like
one
or
hardly
any,
but
after
they
grow
or
you
got
intensive,
more
intensive,
then
full
full
power
on
this
is
necessary
and
if
you
want
to
go
more
intensive
more
than
that,
but
it's
only
20
watts,
though.
A
What
else
we
got
we
got,
don't
want
to
get
too
confusing,
but
okay,
so,
but
for
the
actual
fittings
on
top
of
the
towers.
Oh,
that's!
What's
it
doing
there.
A
So
these
kinds
of
things
that's
convenient
for,
if
you
use
packs
as
the
fittings
on
top
so
the
trick
to
making
all
this
work
is
connections,
you
have
all
the
components,
but
all
the
action
happens
at
the
boundary.
So
how
do
you
connect
things?
How
do
you
not
leak?
How
are
you
airtight?
No
leaks,
no
bugs
getting
in
all
that
kind
of
stuff?
That's
that's
the
challenge.
It's
all.
It
all
happens
at
the
interface.
This
is
an
efficient
way
to
do
your
water
connections.
A
If
you
use
pex
tubing,
it's
it
slides
in
and
that's
it
and
to
release
it.
You
have
to
hold
to
release
it.
You
have
to
hold
on
the
on
the
round
part,
and
then
you
have
to
pull
it
out,
but
this
is
an
instant
connection,
otherwise
you're
taking
maybe
a
barbed
fitting
kind
of
screwing.
The
thing
on
there
takes
a
little
time
put
a
hose
clamp
around
it
all
takes
time.
A
H
A
A
So
it's
not
an
entry
level
thing:
okay,
it's
redneck,
301,.
A
Yeah
so
host
clamps
are
no,
that's
that's
a
cool
thing.
I
look,
I
got
all
excited
about
it,
but
then
it's
it
takes.
G
E
A
Takes
time
yeah,
but
if
you
have
wire,
you
got
a
perfect
connection.
If
you
know
how
to
so,
if
you're
macgyvering
it
and
you
don't
have
some
resources,
you
can
do
that
because
look
at
these
things
so
10
of
these
are
what
is
that
10
of
them
35
bucks,
so
3.50
cents,
that's
pretty
cheap!
So
that's
good
and
it
buys
you
the
time
savings
which
is
worth
it
so
I'll.
A
Take
one
of
these
copy
that
image
and
that's
what
you
would
do
at
the
top
here
just
connect
the
connect
small
stubs
of
hose
wherever
you've
got
the
tower
outlet
just
dribble
it
in
there,
don't
even
need
a
tuba
on
it.
Just
maybe
dribble
it
straight
from
the
fitting.
So
that's
a
quick
way
to
do
it.
A
A
A
People
follow
that.
So
I
mean
this
gets
all
into
the
deep
like
little
details
of
how
you
would
design
this,
but
you
don't
want
to
like
feed
this
pump
at
one
end
and
have
it
go
down
the
line
because
the
first
fitting
is
going
to
get
the
highest
pressure
and
and
you're
losing
pressure
over
each
one.
So
you
don't
know
how
many
fittings
you're
actually
going
to
be
able
to
water
with
that
pump.
A
If
you
split
it
to
both
sides,
you
have
a
higher
chance
of
getting
more
fittings
because
the
pressure
reduction
is
less
because
it's
it's
a
parallel
circuit
at
that
point.
So
do
that
like,
if
you
do
that,
so
where
we
connect
the
the
water
pump,
you
want
to
connect
it
to
the
middle.
So
say
we
got.
Two
water
pumps
connect
one
to
the
one
tower
set
connected
at
the
middle.
A
A
A
A
C
A
A
A
No,
let's
save
all
of
that
for
later
so
wiring
diagram
plumbing
diagram.
So
if
that's
one
one
row,
how
do
we
connect
one
pump
to
both
rows?
Well,
you'd
have
to
fork
it
here.
A
A
A
So
this
is
what
you
would
want
to
do
now.
You
got
a
t
right
there.
So
you're
feeding,
you
know
this
side
and
on
and
here
there's
another
t
where
you're
going
off
into
this
side
once
again
doing
it
down
the
middle.
So
you
get
the
best
pressure
pressure
effects,
so
you
got
a
t
there
t
there
you're
teeing
there
so
here
this
is
your
other
side
here
you
know.
A
C
K
A
Could
do
like
you
can
connect
through
this
yeah
and
and
but
then
you
get
that
pressure
reduction
like
the
the
effect
where
you
want
one
pump
to
to
go
parallel
as
soon
as
you
can,
so
you
can
get
more
outlets
more
reliably
for
the
same
argument
that
we
were
using
before.
If,
if
you're
following
that
argument,
so
you
wouldn't
want
to
connect
at
the
end,
it
would.
A
A
A
A
How
can
you
expand
the
distance
that
this
water
travels
before
it
leaks
out?
All
the
t
t-holes
make
the
outlet
smaller.
You
could
make
this
outlet
smaller,
but
from
experience
we
don't
want
to
be
doing
that
for
for
purposes
of
clogging.
So
I'm
thinking
that
half
inch
is
an
absolutely
robust
distance.
You
can't
get
something
clogging
up.
One
half
inch
go
three
eighths
a
little
higher
chance
to
get
a
hair
ball,
something
in
there
quarter
inch
yeah,
definite
chances.
Eight
inch.
A
A
A
A
Some
yeah
almost
like
a
reservoir
up
there,
but
it
would
still
leak
so
the
only
way
there's
different
ways
to
do
it.
One
way
to
try.
It
is
if
the
fittings
are
actually
pointing
up,
because
then
you
have
to
fit
fill
all
the
fittings.
A
F
There,
in
that
situation,
depending
on
how
much
pressure
you
have,
if
you
might
actually
still
try
and
leave
out
the
first
nozzle,
because
it
is
under
pressure
and
then
I
don't.
A
A
Yeah
you
got
to
be
level,
you
got
to
pay
attention
to
all
of
that,
so
you
got
to
be
careful.
How
you
do
it
and
it
may
may
be
the
same
result.
So
we
don't
know.
A
A
A
B
I
K
A
A
Into
a
little
bit
of
engineering,
so
what
engineering
do
we
have
up
there?
We
have
a
relatively
straight
roof
with
the
board
that
should
be
as
like.
We
should
probably
put
a
level
there
to
make
sure
that
board
is
level
so
we're
starting
at
least
yeah.
You
actually
have
to
start
getting
precise
in
this
if
you
want
to
make
this
work
and
work
properly,
so
that
this
is
why
I'm
saying
this
is
like
this
whole
aquaponics
thing
is.
A
very
complex
system
requires
a
lot
of
different
skill
sets
how
about
a
bigger
like
fatter
pipe.
A
K
K
F
F
A
H
A
And
maybe
like
the
problem
actually
goes
away
from
the
beginning,
because
we
find
that
once
we
divide
into
like
both
sides,
you're
actually
getting
enough
enough
leeway,
so
there
could
be
like
a
like
a
dial.
A
So
how
like
a
fine-tuned
control.
So
what?
If
like
say
the
two
end
ones
we
have
facing
down,
because
they're
the
farthest
away
and
the
ones
before
that
they're
angled
a
little
bit
up
and
even
more
up
so
you're
kind
of
reducing
the
pressure
available
to
the
first
and
then
successively
like
getting
down,
because
you
can
twist
this
t
to
have
the
angle
of
where
the
pipe
at
what
pipe
angle
you're
exiting,
which
would
determine
how
much
back
pressure
you're
putting
on
it.
A
If
you
put
it
straight
up,
you've
got
the
max
back
back
pressure
because
you
have
enough
pressure.
You'll
still
get
water
out
of
that,
but
you're
saving,
more
pressure
for
the
ones
downhill.
So
that
could
be
these
fittings
lend
themselves
actually
to
fine-tune
adjustment.
You
can
turn
them
and
adjust
the
length
of
the
pecs,
because
you
still
want
to
go
neatly
back
into
the
tower.
A
C
A
You
just
need
to
keep
the
plants
wet,
keep
the
roots
wet.
What
is
the
pump
height
of
the
pumps
that
we
have?
Oh,
we
said,
let's
put
it
towards
the
top,
which
is
towards
three
feet
like
two
and
a
half
feet
two
feet
between
two
and
three
feet
like
two
feet.
So
it's
on
the
upper
half
of
the
pump
yeah.
So
we
we
do
that
that
drainage
protection
thing
so.
A
A
So
once
we
start
hitting
these
limits
of
the
small
pumps,
we
might
say
okay
well
at
this
point
we
just
got
to
go
to
the
sump
pumps,
which
would
work
they'll,
definitely
blow
this
out,
but
you're
using
five
times
the
energy,
if
you're
using
it
all
day,
in
which
case
you
can
go
with
saying
I'll
turn
it
on
for
five
minutes
at
a
time
and
do
that,
but
every
time
you
start
up
and
shut
down,
you
know
that
could
work
in
the
heat
of
the
summer.
A
You
want
to
make
sure
you're
shorter
than
like
wilting
time,
because
it
gets
really
hot
in
there
things
like
that,
so
electricity
use,
I
mean
you
can
blow
the
system
out
by
just
getting
more
power
to
the
pump
getting
more
expensive
pump.
That's
an
easy
solution,
but
if
you
try
to
do
it
more
efficiently,
you
think
about
okay.
What
exactly
do
I
need
and
how
much
can
it
support
and
can
be
really
smart
about
using
available
energy?
A
F
Going
to
be
losing
water
all
the
time
you
could
use
so
like
a
float
valve
to
like
from
an
outside
unit
that
catches
rain
water
a
float
valve.
That's
you.
F
It
gets
below
a
certain.
The
pool
goes
below
a
certain
height
and
it'll.
A
Oh,
you
can
with
rainwater.
I
think
it's
pretty
safe,
like,
for
example,
in
jeff's
house
there
we
have.
That
system
is
not
regulated
it
just
spills
over
when
there's
too
much
rain.
In
this
case,
it
will
also
work.
If
you
have
a
rain,
you
spill,
you
spill
it
as
long
as
the
fish
don't
leak
out.
It
depends
if
your
fish
are
jumpy
if
they
like
to
jump
outside,
because
you
have
bad
conditions,
they'll
die,
but
if
you
have
good
conditions,
they
typically
want
to
stay
in
so
they'll,
be
like
oh
cool,
like
clean
water
rainfall.
A
A
B
A
A
So
you
have
to
do
make
sure
that,
like
whatever
the
rain
catchment
is
yeah,
maybe
have
some
kind
of
a
limit
like
either
by
having
a
pipe.
That's
small
enough
or
the
whole
area
of
the
roof
is
there's
only
so
much
or
maybe
you're
feeding
part
of
the
gutter
into
it.
Because
yeah
you
don't
want
to
have
like
a
huge
exchange
of
water
in
like
one
hour.
A
No,
you
you
want
to
be
like,
on
a
date
multiple
days
scale
for
that,
so
so,
whatever
catchment
we're
doing
like
what
is
the
calculation,
if
we
get
a
four
inch
rain,
how
much?
How
much
rain
you
get
off
of
a
256
square
foot
roof?
So
I
guess
a.
A
So
you
have
four
inches
times:
okay,
what's
the
volume
go
to
volume?
Calculator
four
like
four
inches
can
happen
here,
like
that's
happens
here
and
there.
So
what
would
happen
if
we
did
that
we
would
have
length
is
16
feet.
A
A
So
in
a
super
super
heavy
rain,
you're
exchanging
a
quarter
of
the
water
that
might
be
a
limit
of
what
you
can
handle,
in
which
case
you
might
yeah
yeah
put
the
provisions
like
I'm
just
trying
to
say:
okay,
what's
the
what's
the
simplest
least
parts
thing,
but
yeah
float
valve
yeah
what
kind
of
float
valve
you
have
to
take
a
look
at
that
yeah,
some
kind
of
a
bucket
structure
with
a
float
valve
that
closes
on
and
off.
A
You
have
to
pay
attention,
though,
because
if
it
gets
clogged
then
it
doesn't
shut
off
then
you
know,
so
you
want
to
make
sure
you're
resilient.
Whatever
you
design
in
yeah
or
just
have
a
you,
know,
water
level
sensor
that
just
shuts
off
a
valve,
so
how
you
do
things
like
that,
if
you
connect
that
to
arduino,
you
got
these
things,
for
example,
so
I
was
looking
at
what
are
accessible,
larger
valves.
This
is
one
inch,
so
it
can
handle
quite
a
bit.
A
You
know
one
inch
is
getting
significant,
but
that's
you
know
50
bucks
cool,
but
you
can
say
we'll
open
open
this
valve.
Whenever
the
you
know,
the
water
level
gets
to
a
certain
level
and
one
inch
one
inch
might
be
like
just
barely
enough
to
handle
like
a
heavy
rainfall.
It's
probably
from
like
a
256
square
root
in
truth,
they'll,
be
they
probably
need
like
a
couple
of
these
to
to
handle
like
a
full
heavy
rainfall.
A
So
that's
we
should
try
the
well.
I
mean
we
can
play
with
this,
so
to
figure
it
out.
But
the
first
thing
is
just
try
this
and
see
if
all
the
towers
get
wet
and
that's
that's
step
one.
So
does
anyone
have
any
other
proposal
for
what
a
better
hydraulic
diagram
would
be?
So
that
thing
is
where's
this
where's,
this
other
pump
coming
from.
Well,
we
can
connect
just
one.
What
happens?
How
do
you
connect
two
of
them?
A
Well,
you
have
to
t
in
another
one
towards
close
to
that
one,
but
a
lot
of
that
would
leak
down
here.
So
you'd
have
to
have
a
check
valve
on
one
and
the
other
to
prevent
backflow
into
the
other
pump.
If
the
other
pump
is
dead,
so
check
valve
a
little
inline
check
valve,
which
so
say,
half
inch
now
check
valves,
yeah
those
like
to
be
clean,
so
a
half
inch
check
valve.
A
You
could
get
a
easy
one
like
just
simple
thing
like
this:
in
line:
oh
yeah,
five
bucks,
if
we're
using
half
inch
lines
well,
those
are
three
eighths,
but
basically
you're
letting
water
through
one
way
and
it
doesn't
flow
back
the
other
way.
So
do
something
like
it's
a
water
diode.
A
J
J
A
A
If
you
have
two
on
at
the
same
time,
you
don't
need
that
check
valve
it's
more
for
the
pump
failure
condition.
So
we
can
add
the
second
one,
but
maybe
maybe
one
is
even
enough
for
20..
I
kind
of
doubted,
though
someone
already
have
it
built
in
as
well
yeah,
so
we
can
try
this.
A
What
else
do
we
need
to
know
about
the
towers?
So
that's
one
system.
So
what
about
we're
like
going
into
lunch?
So,
let's
do
build
outs
in
the
afternoon,
but
what
else
do
we
want
in
there?
I
definitely
would
want
a
growing
bed
in
there.
A
So
what's
a
growing
bed,
look
like
open
box
yeah
it
gets.
It
gets
pretty
heavy
if
you
fill
it
with
soil.
So
what
I
would
suggest
is
if
we
do,
that,
put
a
bunch
like
layers
of
straw
and
soil
on
it
and
the
straw
decomposes
over
time,
but
it's
much
more
lightweight.
It's
much
more
humus,
so
it's
lightweight
compared
to
like
clay,
which
is
very
heavy,
so
do
a
box.
A
That's
like
we
would
like
to
do
something
like
four
by
eight
and
then
put
a
pot
once
again
pond
liner,
so
the
stuff
doesn't
rot
on
you
and
then
you
do
want
to
drain
out
of
that,
because
you
don't
want
to
flood
the
bottom,
so
you
have
to
poke
a
hole
at
the
bottom,
where
you're
leaving
basically
just
put
some
kind
of
a
fitting
in
there,
where
you're
doing
the
best
you
can
or
well
actually,
if
you've
got
just
don't
make
the
like
a
pond,
put
the
one
piece
of
poly
on
the
bottom
and
then
put
more
like
on
the
sides.
A
A
So
what's
a
basic
design
of
a
grow
bed
I
mean
growbed
could
be
anything.
It
would
be
as
simple
as
as
four
boards
on
the
ground
in
the
space
we
have,
but
that's
not
a
great
use
of
space,
nor
is
it
comfortable.
The
growbed
idea
is
that
you
have
comfortable
working
height,
so
it's
really
convenient,
so
a
convenient
way
would
be
to
stand
it
on
legs.
Just
like
we
saw
back
in
our
photos.
A
Yeah
I
mean
grow,
bed
is
just
comfortable.
Main
thing
is
about
comfortable
working
height,
so
you
can
plan
things
and
without
bending
over
and
things
like
that,
it
should
be
like
soft
enough
that
you
can
harvest
the
plant
plant.
Another
one
right
away.
Let's
see
do
we
have
any
evidence
like
this
stuff
in
the
front
here.
That's
the
grow
bed.
So
it's
you
know
it's!
You
see
the
black
side
there
that's
polyethylene
covering,
and
we
had
it
where
we
wrapped
it
all
the
way
up
towards
the
bottom.
A
I
mean
not
really
if
it's
in
contact
with
things
you're
going
to
eat,
so
you
don't
want
to
do
the
treated
stuff
and
in
this
diagram
here
we've
got
treated
for
the
shelves
they
are
treated,
but
that's
because
the
nuts
are
going
out
into
the
field.
That's
not
in
the
food
contact
and
then
the
polyethylene
on
top,
so
you
don't
have
a
lot
of
contact
with
with
the
biological
systems.
K
A
You
got
four
by
eight
four
by
eight
sheet.
Do
that
I
mean
you
have
to
support
the
bottom.
That's
a
lot
of
weight
if
you've
got
plants
and
soil,
for
which
reason
we've
got
the
huge
bell
by
the
other
house.
A
We
should
grab
like
a
whole
bunch
of
it
and
and
use
that
as
me,
because
if
you
just
put
plain
soil
in
there,
you
really
need
lightweight
soil
mix
and
one
way
to
do
it
easily
is
take
the
clay
soil
here,
but
just
put
in
a
bunch
of
bunch
bunch
of
the
straw
in
it
and
as
it
decomposes
it'll
it'll
work.
You
can
start
growing
things
in
there
and
then
coat
it
put
a
coat
of
soil
on
top,
so
you
can.
A
The
plants
can
establish
readily
and
then
that
the
straw
will
get
give
it
all
the
volume.
That's
that's
one
way
to
do
it
like
at
a
low
budget,
otherwise
you're
getting
a
whole
bunch
of
bags
of
a
lightweight
salt
mix
or
or
things
like
expanded
clay.
A
There's
there's
a
couple
ways
to
do
these
things.
You
can
do
them
just
like
soil
based
or
aquaponic.
More
aquaponic
based
aquaponic
based,
would
be
expanded.
Clay,
pellets.
A
You
can
get
this
stuff,
but
it
ain't
cheap
either.
You
know
this
kind
of
stuff
which
which
plants
grow
directly
in
it.
In
a
flood
like
you
flood
the
plants
that
kind
of
retains
the
moisture,
it's
expanded,
so
the
little
little
spaces
between
hold
water,
but
this
is
like
45
liters
for
like
about
40
bucks.
So
it's
like
a
dollar
per
liter.
You
know
not
too
cheap
hay
bales
you
can
get
for
free.
You
can
get
salt
almost
for
free.
A
F
C
A
Ideally,
the
ecosystem
would
take
care
of
itself
in
the
best
scenario.
A
They
will
get
into
the
they'll
go
in
there.
Oh
really
yeah,
because
yeah
they
will
I've
seen
this
one
farm
where
it's
like
they
had
this
with
the
fish,
water
and
just
worms
all
over
the
place
yeah
in
this
medium,
so
yeah,
the
worms
will
love
this
stuff
too.
It's
as
long
as
you
got
a
moist
environment
that
you
can.
A
A
This
we
don't
have
the
materials
for
this
one,
so
let's
just
use
the
soil
based
and
that's
like
in
practically
speaking.
You
know
it's
probably
if
you
got
a
whole
bunch
of
these.
You
know,
you'd
have
a
bunch
of
cost
and
nest.
That's
45,
liters!
Well,
that
was
40,
10
gallons.
How
big
is
this
bed?
If
we
have
it?
One
foot
deep
like
four
by
eight
one
foot,
is
a
good
depth.
That's
enough
for
root
crop.
A
How
many
gallons
is
that
it's
about
times
seven,
so
it's
about
220,
gallons
or
so
so
you
need
like,
if
there's
forty
five
bags
of
that
according
to
that
price,
that
would
cost
you
like
five
times.
Forty
like
two
hundred
dollars
for
that
for
the
grow
medium.
Well,
you
can
pay
that,
but
you
can
also
get
it
could
be
convenient.
It's
I
think
it
lasts
for
a
long
time.
A
220
well,
no
no
hold
on
there.
I
miscalculated
220
gallons,
that's
880
liters.
A
That's
a
lot:
that's
like
nearing
a
thousand
bucks
per
bed.
That's
not
worth
it!
I
mean
this
stuff
ain't,
cheap!
That's
the
thing!
Maybe
in
bulk
you
can
do
better,
but
that
that
was
my
first
thing.
It's
like
you'd
think
this
would
be
a
little
more
affordable,
but
any
of
these
engineered
media
they're
quite
expensive.
I
But
you
can
just
put
a
ratio,
you
don't
have
to
put
it
a
hundred
percent
yeah.
I
I
Of
this
black
black
soil,
like
it's.
I
A
well-known
technique
that
they
heat
the
wood-
this
was
carbon
and
then
they.
G
I
I
And
then
it's
like
you
put
it
as
a
part
of
the
slow
bed
yeah
and
it
helps
retain
the
nutrients
yeah
and
also
it
retains
the
water
as
well.
A
Yeah
yeah,
that's
yeah,
that's
great
charcoal
is
all
good.
E
B
E
I
can
make
some
suggestions
of
things
that
I've
used
to
fill
in
like
raised
beds
that
are
cheap
as
much
instead
like
mulch,
like
sometimes
I'll
do
like
50
percent
mulch,
like
you
get
like
the
the
moles,
will
decompose
really
quickly
and
will
form
like
a
very
light
mixture
with
your
glycerol
or
whatever
style
you
put
in
there.
E
It
mulch
is
cheap,
get
the
non-colored
one,
of
course,
like
chemicals
in
it
or
something
yeah.
Another
thing
that
is
quite
cheap.
It's
like
450
or
five
dollars
per
bag.
I
guess
and
well,
and
one
bag
is
40.
E
Like
pallets,
but
the
pellets
that
you
use
for
burning
need
a
stove
they
just
basically
as
soon
as
you
mix
them
or
they'll
crumble,
they'll
turn
into
sawdust
and
obviously
like
safe
sawdust
from
any
non-treated
materials
that
you're
cutting.
E
C
A
Yeah,
that's
right!
So
what's
the
height
of
this
thing,
it's
we
want
to
make
it
comparable
to
a
table
height
which
is
like
30
to
40
inches,
something
that's
comfortable
working
height
like
like
this
here,
so
you
can
can
be
most
comfortable.
So
that's
that's
the
main
determinant
there.
So
we
should
make
it
like.
I
don't
know
like
34
in
maybe
like
three
feet
or
30
inches
to
three
to
four
feet.
A
So
you're
working,
the
top
of
it,
is
probably
like
around
here
and
the
base
is
there,
so
you
also
don't
have
the
legs
are
in
too
long.
You
could
use
treated
like
say
the
4x4
treated
for
the
legs
and
then
or
you
can
do
a
box.
I
mean
2x12
is
quite
convenient
for
that
for
here,
so
you
do
2
by
12
for
the
box
and
then
for
the
legs.
You
can
either
do
like
a
flat
on
two
by
twelve
or
just
four,
by
fours.
A
Four
by
fours
are
a
little
harder
to
attach
because
you
you'd
need
like
longer
screws.
If
you
do
legs
that
are
flat
on
on
the
sides,
that's
an
effective
way
like
in
fact
like
legs
that
go
like
this
on
each
corner.
That
would
make
for
a
very
strong
connection,
with
minimal
lumbar
like
two
by
fours
or
two
by
sixes,
or
something
like
that,
and
this
would
want
to
be
painted
for
longevity.
Otherwise,
it
decomposes
after
a
few
good
years,
so
2
by
12,
is
now
the
bottom.
A
It
wants
to
have
a
bottom,
that's
going
to
be
heavy!
So
so
that's
that's
the
other
issue.
So
at
the
very
bottom
you
want
to
probably
have
legs.
This
thing
is
going
to
be
like
really
heavy
like,
so
this
is
big
infrastructure,
so
across
the
bottom,
so
you
probably
want
either
2x12
boards
at
the
bottom
and
then
probably
a
support
across
that
because
it
will
just
blow
out
after
some
time
so.
G
A
Put
on
the
floor,
you
can
do
that
and
then
it's
not
as
comfortable
to
to
work
it
like
it's
super,
convenient
to
to
put
it
at
a
height
that
you
can
work
easily.
At
I
mean
that
makes
a
difference
because
otherwise
it's
yeah
it
does
make
a
difference.
So.
A
We
can
design
it
either
way,
but
we
had
one
that
was
just
you,
water
them
and
if
it's
not
part
of
the
automated
system,
that's
one
little
task
you
have
to
do,
but
it's
not
too
bad.
If
you're,
if
you're
managing
it
constantly,
then
yeah
watering
is
not
easy.
Just
take
a
bucket
from
the
fish.
F
A
Yeah,
so
that's
that's
kind
of
where
we're
at
on
that
yeah
I
mean
we
can
get
out
a
bunch
of
two
by
twelves
and
it's
once
again
it's
we
can
look
at
the
one.
That's
in
jeff's
greenhouse
there.
That's
a
good
model.
That's
that's!
I
don't
know
if
we
have
the
blueprints
for
that
on
that
one,
I
don't
think
we
ever
did,
because
it
was
too
easy
to
to
just
do
like
in
place.
A
A
A
Yeah
for
for
the
straw
there
we'd
have
to
grab
some
from
the
the
cdc
home
to
site
for
the
the
straw.
I
would
do
that
because
man
you'll
see
like
the
amount
of
salt
you
got
to
put
in
there.
That's
a
lot.
You
just
don't
have
the
like
bags
of
composter
or
like
pre-made
soil
like
lightweight
soil
mix
on
hand
yeah,
but
the
straw.
The
straw
route
is
a
practical
one.
For
this
you
can
get
things
to
grow
and
they're
pretty
immediately
the
way
they
some
people
do
like.
A
A
Then
you
can
put
pockets
of
soil
where
you
actually
have
that
good
growth
medium
and
then
it
all
gets
all
wet
and
decomposed
and
biological
in
there
and
full
of
nutrients
that
if
you
have
the
aquaponics
water,
that's
that's
also
providing
the
nutrients
into
that
cyst
that
growing
bed
so
it'll
be
a
quite
a
workable
system.
Just
with
a
with
a
straw.
A
Just
one
so
how
much
space
do
we
have
in
the
greenhouse
there's.
A
If
it's
eight
feet
long,
you
could
only
fit
one.
So
I
mean
what
we
got
for
this
yeah
and
then
we
can
also
talk.
We
have
we've
got
these
elongated
troughs,
but
yeah
between
these
two
projects.
There's
plenty,
I
think
plenty
for
everybody,
so
we
can
get
a
team
on
there's
finishing
up
of
the
all
the
wall
modules.
Just
a
little
detail
like
the
quality
control
detail,
getting
the
growing
towers
a
lot
of
the
stuff.
A
The
raw
materials
like
the
fittings,
are
on
a
shipping
table
at
the
south
end
of
the
greenhouse,
so
we
can
unpack.
All
of
that.
Most
of
that
is
is
there
we
can
make
it
make
it
all
work,
but
we
can
basically,
the
polyethylene
is
on
the
side
there.
We
can
start
laying
it
out
doing
the
corners
and
just
get
the
hose
to
it
and
fill
it
we're
at
that
stage.
We
can
pretty
much
fill
it.
I
think
as
how
the
corners
do
we
do
all
the
corners
on
it.
A
K
In
the
last
link
in
the
chat,
there's
like
five
things,
we're
signing
up
for
today,
it's
a
lot
of
work.
K
A
What
take
what
we
have
energy
for
the
main
thing,
the
in
priorities.
I
would
get
the
water
system
and
and
towers
going
the
other
stuff.
It's
button
up
details
we
to
to
make
this
work
well.
We'd
have
to
we'd,
have
to
do
it
to
to
actually
get
it
going
and
started.
A
F
And
then
martian.
C
F
Instead
of
doing
the
session
in
the
morning,
yeah.
C
F
H
There's
also
the
aspect
that
we
spoke
about
in
the
morning
about
weekends,
starting
at
11.
G
A
A
A
Okay:
let's
do
that,
let's
break
for
lunch
and
get
out
there
at
one
so
I'll
stop
this.
