- Open Grow Sponge package, put the sponges into the water of the seedling tray, press the sponges into water for 5 seconds and ensure the sponges absorb water completely.(Fig1)
- Place the seedling tray with cover in the shade or cover it with black cloth(to block light).
- Spray water and keep the sponges wet every day.
- During 0-7 days(leaf plant), find the sprouted ones in the tray; pick them out, move them into the growing holes and keep the remaining seedlings.
- Discard unsprouted sponges after regular germination time.
- The different plants may have different germination times, please check before planting.
- Chart II: Plant Stage.
Seedling Stage
- When the germination rate exceeds 70%, move to the seedling stage, and discard excess sponges. Move all sponges to the grow tube and set them up in balance depending on plant size. In each sponge, keep strong plants and cut the other weak plants.
- Use a spoon to add the nutrition powder to the water tank and ensure that the EC is between 1000-2000 μS/cm.(=1.0-2.0 ms/cm).
- Ensure pH between 5.5-6.5 (adjust by pH adjusters). 13 inches Adjust LED lights and keep around 2 inches distance to cover all the plants.
- For EC & pH adjustment instructions, please refer to user manual pages 28-29.

Regrowing
OPCOM Farm is designed with a special re-grow process to maximize harvest capacity for family consumption. The first harvest cycle takes 3-4 weeks after the seeding the young plant is planted. During harvesting, cut out the larger leaves and allow the smaller ones to continue to grow in the machine. After the first harvest, you can continue the harvesting method weekly for the next 3-4 weeks without the need to re-seed.
Sprout Process
GrowWall is not only a hydroponics system but also a Sprout Machine with our free gift, a sprouting box. Within one Hydroponics cycle time, you can have 3-4 sprout harvests and each harvest cycle is 7-10 days. Enjoy your maximum planting capacity. Refer to user manual pages 24-25 for details.
Troubleshooting
Lamps are not
lighting up
| ☑ 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 the pump still does not work, replace it with a new OPCOM pump (OAEE06A).
Refer to pump box for installation.
The pump has a buzzing sound| ☑ 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 the air entering the pump. Over time this may shorten
the life of the pump. Please maintain the correct water level at all times.
☑ If the pump is failed, replace it with a new OPCOM pump (OAEE06A). Refer to
pump box for installation.
The lamp or the pump stopped working after a few hours| ☑ 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, offering the best growing condition for your plants, and saving you energy.
☑ Check the user manual page 15 for cycle descriptions.
GrowWall Q&A
