GrowBox & GrowWall

Do I have to know how to garden to use a GrowBox or GrowWall?
Not at all! Farming the OPCOM way does not require gardening experience. While it is useful to gain an understanding of how plants grow and what makes them thrive, previous soil-based gardening experience is not necessary. Everyone can grow in their own indoor environment; follow the instructions and check on your water weekly.

Where should I put my unit?
They can be placed anywhere indoors, in a variety of environments – not only in the kitchen or dining room, but also in a hobby room or even spare bedroom.

GrowBox should be on a sturdy surface that can support 70+ pounds. The important thing to remember is to maintain a stable indoor temperature; because of this a garage is not a good option. Note also that GrowWall leans against a wall, and to preview tipover accidents, it must be secured to the wall.

How much space do they take up?
GrowBox has a footprint of 41*28 inches with height starting at 23 inches. GrowWall has a footprint of 58*12 inches, with a height of 75 inches.

What type of hydroponic system are these products?
GrowBox is a Deep Water Culture system, while GrowWall is an Ebb and Flow system, also known as Flood and Drain.

What is the wattage of the light bulbs?
GrowBox: 4 bulbs at 18 Watts each; GrowWall: 5 tubes of 30 Watts each.

Can I use the units in commercial environments?
Absolutely. The systems provide a living, breathing ambience to restaurants and any commercial kitchen or cafeteria such as in offices and hotels. It can serve as a community garden in a condo building. We also highly recommend the products for educational environments.

How much water is required to fill the unit?
Up to max 4.2 gallons for GrowBox, and 7.9 gallons for GrowWall.

Growing

What does hydroponic mean?
With hydroponic gardening, plants grow without soil and receive their nutrients directly to their roots through water. In a hydroponic system, we can control the environment and offer plants optimal conditions for growing.

How often do I need to check pH, nutrients, fill water, or do any other maintenance while plants grow?
Once a week, check EC reading to see if you need to refill nutrients. If refilling, you should wait 30 minutes before checking the pH reading to make sure the water is optimal for the plants to absorb their nutrition. Also check water level to refill what has evaporated or been absorbed by your plants.

How long are water and lights on in Auto-mode?
In Auto mode, lights are 12 hours on, and 12 hours off for both units. The pump cycle is 1 hour on, 5 off for GrowBox, while for GrowWall, the pump is 30 min on, 90 min off. The difference is due to GrowWall being an “ebb and flow” system where roots get water only during pump cycles..

What do I to prevent algae in the unit?
Like your plants, algae also thrive on light and nutrition. To prevent light from reaching the water tank, you may plug unused holes with sponges, and cover the sprout box.

Can I move plants during growth?
Yes, if you move them carefully and make sure roots all are placed down into their new hole, it is not a problem to move them.

Do the units grow marijuana?
The crop has many special requirements, which are not supported by our systems. Our lights are optimized for vegetables and leafy greens, and would not work for that purpose.

How much electricity do the units use, and how much does it cost?
GrowBox uses 0.9 kW per day in Auto mode, and GrowWall uses 2.4 kW. For a typical full growth cycle of lettuce in a GrowBox of 2 days off, 5 days on, and 35 on Auto, the total useage is 35kW. Utility costs vary among markets, but for a national average this is less than $5 per full growing cycle.
