Please note the power supply will get hot to the touch. The high temperature is normal but could cause adverse effects on
certain materials such as linoleum, countertops, wood and carpet. Do not place in direct sunlight. Keep away from children.
If you have concerns we recommend using a cord storage box.

ASSEMBLING YOUR
GLOW R ING S
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.

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.
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 Glow Ring and
lock it into place.
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.

W HEN TO G E T
GLOWING
You will have two timers: one for your Glow Rings and one
for your water pump. 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 pump and Glow Rings timer.
We recommend setting your timer so that your Glow Rings
turn on during the day and turn o at night. It is 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.
Plants need rest just like we do! This will also create a less
intrusive environment for your home since the Glow Rings
will turn o at night.
View the light cycle timer setting for each Glow Ring size in
the table below.
The Farmstand’s watering cycle will be dierent when the
Glow Rings are on than when they are o because seedlings
do not need as much water or nutrients when the Glow
Rings are o. Use the ‘Lights On (Day)’ watering cycle when
your lights are on and the ‘Lights O (Night)’ watering cycle
when your lights are o. View the watering cycle for Glow
Rings in the table below.
