The Roto-Gro garden is a rotating flood and drain hydroponics system.

Once a day, the top plant tray is filled (from the lower main reservoir) with liquid nutrient until all the trays have passed through. Plants are securely seated in quick-drain trays using Grodan 4" x 4" x 2.5" Gro-Blocks.

The motorized Roto-Gro wheel revolves around two center-fixed, fan-cooled, growlights. It takes about one hour for the Roto-Gro wheel to complete a revolution and is in a constant motion 24 hours a day.

Now you can grow your garden using only 1/3 of the space and power of traditional hydroponics systems. Built of lightweight plastic and fiberglass. Takes about 1 hour to assemble.

Manufacturer's Growing Tips

When using Rockwool or equivalent cubes, they must be pre-soaked before use. Fill reservoir with water and set PH level at 5. Place cubes in reservoir and let soak for 24 hours.

Drain and clean reservoir. Refill with fresh water, setting the PH level at 5.6.

Add an air pump with air stones into the reservoir and plug into leg of machine. This is necessary to oxygenate the water.

After plants have been inserted into cubes and placed into trays, it is important to have them root into the bigger cubes before feeding them. Keep the lamps on 24 hours a day until rooted. Check the cubes daily to make sure they are still moist. Do not let them dry out! If it is necessary to flood the cubes before rooting has taken place, keep the nutrient level low, eg. 500 PPM.

After root development, increase nutrient mix to 1500 PPM and flood only when needed (making sure the cubes do not dry out) until noticeable plant growth, then daily floods are recommended.

It is recommended that you add a bacteria/mold inhibitor to the nutrient mix.

It is a good idea to position 1 or 2 fans in the direction of the grow area to help move CO2 around the plants.
