A Sunny Outdoor Spot (or Indoors With Lights)
Plants grow best with at least 6 hours of direct
sunlight per day (or 14 hours with indoor
growing lights).
Note: Avoid placement next to tall trees or buildings
that will limit sun exposure.
Indoor Growing Tips
For all indoor Farmstands we recommend placing
it on a mat to avoid water dripping o plants and
onto the oor.

Before starting, make sure you have all of your components,
including the Glow Rings if you’re growing indoors. If using
Glow Rings, jump to page 8 for assembly instructions. Attach
the pump tting, pipes, and coupler tting to the water pump
(as pictured).
Check that the pump is open to water ow by ensuring the
pump switch is ipped in the UP position. Then, place the
pump inside the tank with the pipe attached, axing the
pump’s suction cups to the bottom of the tank. Be careful
not to damage the plastic lm at the top of the tank as it
prevents water leaks.
Run the pump’s electrical cord through the opening
on the side of your tank.
Push the pump’s electrical cord into the opening on the
bottom of the gasket that doesn’t have a small plug installed.
The second opening is intended for lights produced by
Lettuce Grow. If not in use, leave the plug in the second
opening to prevent water leaks. For more information,
go to www.lettucegrow.com/lighting
Line up the groove on the gasket with the edge of the tank
opening and pop the gasket into place. It will t very snugly
and you may need to bend it to pop it into place!
Snap the cord into the cord seam on the outside of the tank,
then snap the tank cap into place over the gasket.

ASSEMBLY
Place the rst growing level over the pipe and slide
it down to the tank with the seedling port holes on
the bottom.
Align the growing level so that it sets into the groove,
then twist to lock in place. The circle icon should line
up with the open lock icon before twisting. The lock
and circle icon should line up once locked. Repeat for
all additional levels.
Note: You can have your port holes line up
vertically or alternate - it’s your choice!
If you ordered a 30- or 36-Plant Farmstand, your
additional growing levels will ship separately.
Locate the water diuser and place it on top of the pipe
as pictured in the diagram to the right. Then place the
Farmstand lid on the top level and lock it into place.
You’ll notice that you received a hose coupler. This is
used to remove the water from your Farmstand tank
and is not needed at this time.
DO NOT plug in your Farmstand yet.

ASSEMBLING YOUR FARMSTAND
WITH GLOW RINGS
If you already have a Farmstand, begin by
unplugging your Farmstand, removing the lid,
diuser cap, ll port cap, gasket, and all modules
except for the rst one. If you are setting up a new
Farmstand follow the Farmstand Assembly guide
and add just one module. For all indoor Farmstands
we recommend placing it on a mat to avoid water
dripping o plants and onto the oor.
Set aside your top single-cabled Glow Ring (you’ll use
this last). The two ends of the dual-cabled rings will
arrive screwed together. You will need to unscrew
them in order to connect them to the rings above and
below. Pass the connector side of the power supply
cord through the ll port opening and up through the
center module hole. Make sure the cord goes down
before up, creating slack in the cord.
Attach the rst dual-cabled Glow Ring to the top of
the rst module. Once attached, connect the ring
cable to the power supply cable. The cap should be
screwed until it meets the tip of the arrow. A tight
connection will protect from water damage and is
important for the longevity of the lights.

Get your next module level ready and feed the longer,
non-connected Glow Ring cable up and through the
center hole before you attach the second module to
the rst Glow Ring. Hint: It’s easier to feed the cable
through the module center before locking the module
in place.
Repeat step 3 & 4 for each dual-cabled Glow Ring and
module, and save the top single-cabled Glow Ring
for last. The short connector cords should always
connect to the lower ring, and the longer connector
cords should always thread up to the ring above.
Attach the single-cabled Glow Ring to the top module
and connect the long cable from the ring below to
the single cable connection. There should not be an
unconnected cable once all Glow Rings are installed.
Any unconnected cables will cause damage to the
device.

ASSEMBLING YOUR
GLOW RINGS
The small pipe extender and coupler (received in
the Glow Rings box) should be placed at the top of
the pipe stack, closest to the diuser. Note: Pipe
extensions and couplers are only needed for 24-, 30-
and 36-plant Farmstands. 36-plant Farmstands will
need two pipe extensions and two couplers.
Remember to put the diuser cap on and then the
lid can attach to the top Glow Ring.
Aer the Glow Rings are assembled, run the power
supply cord through the second hole in the ll port
gasket. If there is a temporary plug in that hole you
will need to remove it. When you lock the gasket into
place make sure there is enough slack so that the
power supply cord drops down into the Farmstand’s
tank before it goes back up and connects to the rst
Glow Ring, as shown in the graphic to the right.
Note: To prevent damage or malfunction, never
drape anything over or hang items on Glow Rings.

SETTING UP THE TIMERS
Place the second electrical gasket onto the timer plug,
then plug the timer into a GFCI outlet. Switch the
standard setting to TIMER. The ON switch is intended
to leave the pump on, or for testing functionality.
Do not plug in your Farmstand until aer you add water.
For more info on setting up your timer,
go to lettucegrow.com/timer

Locate one of the two electrical gaskets and place it
over the 3-prong plug on the pump cord. Then plug
the pump into the timer.
Set the timer:
First line the arrow up with the current time, paying
attention to the day and night sides of the dial.* Then
adjust the prongs to match your growing conditions.
You can adjust your settings as the season changes.

WATER CYCLE TIMER
Note: If you’re growing outdoors you will have one timer for your
water cycle. If you’re growing indoors with Glow Rings, you will have
one timer for your water cycle and one timer for your light cycle.

SETTING UP THE TIMERS
12
The watering cycle will be dierent when the Glow
Rings are on than when they are o so it’s important
to make sure the timers are synced to the same time.
Make sure the arrow is lined up to the current time
of day on both your water cycle timer and Glow Rings
timer.
In the timer image to the right, we have the 14 hour
light cycle on during the day (light side of the dial).
It’s important that your plants are not stressed by
too much or too little light, so mimicking the natural
outdoor photoperiod is one of the best ways to ensure
they grow successfully.
If you’re assembling with Glow Rings, please reference
the table below for the light cycle timer settings.

We suggest a weekly maintenance check on
your pH level as it will increase over time.
For more info on adjusting your pH,
go to lettucegrow.com/ph.
Now that you’ve assembled your Farmstand (and lights if you’re
growing indoors) and received your seedlings, it’s time to start
growing! We’ll show you how in a few easy steps.
Remove the tank cap and ll the tank with water using
a garden hose or watering can until the water level
reaches the bottom of the tank opening.
Add 4 scoops of Nutrient A to the full tank of water
using a 1 Tbsp scoop and stir thoroughly. Separately add
4 scoops of Nutrient B using the other 1 Tbsp scoop and
stir thoroughly. This is the initial dosage only. For your
weekly maintenance, see the dosage guidelines located
on the back of each bag or check out our app. You can
store your scoops in the bag with the nutrients.
Now check and adjust the water’s pH to ensure your
plants can optimally absorb the nutrients.
Fill the test bottle with 5 mL of water from the tank.
Add 5 drops of pH test solution to the water and place
the cap on the bottle. Give it a swish and match your
water to the color chart included with your pH Test Kit.
The ideal range is 5.5-6, but don’t stress if it is a little
over or a little under.
If your pH is too high, add 1 scoop of pH down to the
tank using the 1 tsp scoop. Stir the tank reservoir, rinse
the Test Kit bottle with fresh water, and re-test aer the
pump has been running for a few minutes. If you have
hard water, it is common to add multiple scoops.
Plug in your Farmstand.

Hose lling up tank
Note: It is helpful to have your pump running when you
mix nutrients and pH down to help them dissolve quicker.

If you are resetting your Farmstand between seasons or xing pH issues,
emptying your Farmstand is super simple and hassle free! You’ll need the
hose coupler that came with your Farmstand and a standard garden hose.
For your safety, DO NOT move your Farmstand
when the tank is full.
Unplug the timer, then remove the lid and water
diuser.
Screw a hose into the hose coupler and attach it
to the inner pipe.
Plug your timer back in, setting it to ON instead
of TIMER. The pump will empty the Farmstand.
Once the Farmstand is empty, remove the hose
coupler and place the diuser and lid back on
your Farmstand. Switch the timer setting back
to TIMER.
QUARTERLY MAINTENANCE
Every 3-4 months (once a season), we recommend
harvesting all of your plants and giving your
Farmstand a deep, thorough cleaning. We call this
a reset. It involves disassembling the Farmstand,
removing old plant debris, and washing the
components in a mild solution of dish soap and
warm water. Once everything is sparkly clean
again, rell your Farmstand. Once in a while, you
should check your pump for any debris buildup
and remove it with a high-pressure hose if possible.

PLANT SEEDLINGS
Time to get planting!
Place each seedling in a separate grow cup on your
Farmstand, referencing the label on your seedling package
for recommendations on where to place them. Keep large
veggies like tomatoes, squash, and broccoli toward the
bottom. Place seedlings anywhere you like if there are
no recommendations.
For planting tips, go to lettucegrow.com/planting
WHAT TO EXPECT
+Be sure to push the grow medium down into the cup. The
grow medium is designed to retain moisture in between
watering cycles. You may notice discoloration due to nutrient
and algae build up. This is normal and not harmful to the plant.
+Cotyledon leaves (the rst leaves a plant develops when it
germinates) will yellow and die o as the plant matures.
WEEKLY MAINTENANCE
+Check and adjust the water level in your tank
+Add nutrients
+Test and adjust the pH of your water
+Plant new seedlings in available ports
for continuous growing
HARVEST!
(and order more seedlings)
Cut and Come Again (Partial Harvest):
For certain plants like herbs and leafy greens, you can
harvest a few leaves, strands, or bits of plants at a time
when you just want to use a little bit. Start by harvesting
the oldest, outer leaves rst and leaving younger, inner
leaves intact until grown to maturity.
Full Plant Harvest:
For greens like lettuces and cabbage, we recommend
harvesting the full plant. This helps to prevent pests,
keeps your Farmstand clean, and allows you to grow
more plants! Simply pull the grow cup out of the
Farmstand, remove the roots (and compost them), and
rinse and re-use the grow cup for your next seedling.
