Troubleshooting
GrowWall Q&A
Checkpoints / Solution
☑ Make sure all power cables are connected.
☑ Power button is turned ON.
☑ Make sure LED status is not OFF.
☑ If on AUTO, HI or LOW there will be periods of time during a 24-hour cycle when lamps are off.
(See the user manual page 15 for cycle descriptions.)
☑ If a lamp has burned out or does not work, replace with a new OPCOM LED tube (OAEE07A).
☑ Make sure the pump’s cable is correctly plugged into the control box.
☑ Make sure Pump status is not OFF.
☑ If on AUTO, HI or LOW there will be periods of time during a 24-hour cycle when lamps are off.
(See the user manual page 15 for cycle descriptions.)
☑ If the pump still does not work, replace with a new OPCOM pump (OAEE06A). Refer to pump box for installation.
☑ Pump may give off a buzzing sound in the beginning due to air inside the pump. After a minute with water
running through the pump, this should be reduced.
☑ Too low of a water level in your GrowWall may have resulted in air entering pump. Over time this may shorten
the life of the pump. Please maintain correct water level at all times.
☑ If pump is failed, replace with a new OPCOM pump (OAEE06A). Refer to pump box for installation.
☑ Opcom Farm’s control box is designed with Auto, HI and LOW cycles, which will turn the lamps and the pump on
and off at certain intervals. This is to mimic an outside daily cycle, offer the best growing condition for your
plants, and save you energy.
☑ Check the user manual page 15 for cycle descriptions.

The lamps provided with your GrowWall is standard OPCOM 30W (L30T) LED Growth Tube. This is suitable for
most plants’ growth. You may also use OPCOM Professional LED Growth Tube 65W (L65T) to accommodate
special growth needs.
During the delivery in vessels, aircraft, or other vehicles, it may lead to damages in GrowWall(OFG003)/
GrowWall2(OFG003-2) and creates leaking problem. OPCOM FARM provides waterproof tape for you fix it
