These flexible hydroponic growing "pods" are a popular addition to the GH line of quality hydroponic systems.
The WaterFarm is their best selling hydroponic module. The unique square design enables you to pack many WaterFarms together with close spacing for large installations.
The WaterFarm will grow small, medium, and large plants up to tomato, cucumber and pepper size. A Controller System is available allowing many WaterFarms to be interconnected allowing expandability that emulates commercial setups.
In the Waterfarm, plants are grown within a chamber that is filled with a fired clay pebble hydroponic medium. This growing chamber is suspended above a reservoir filled with nutrient-enriched water.
An electric air-pump drives the nutrient solution up through the "pumping column" where the nutrient then drips down through the fired clay pebble. This infuses the nutrient solution with oxygen and constantly bathes the roots, stimulating the plant to grow - grow like you've never seen before!
Individual WaterFarm Complete Modules include a 4 gallon reservoir, a 2 gallon growing chamber, pumping column, column support tube, drip ring, 1/2 inch grommet, drain level tube, Elite 800 air pump, 9 liters of Hydroton fired clay pebble growing medium and the 3 part Flora series nutrients.
The optional Controller Systems are very simple - a container with a float valve is connected to the line of units. A master reservoir filled with fresh water and mild nutrient is located on top of the float valve actuated Controller.
As the plants draw water from their individual reservoirs, the liquid levels drop causing the float valve in the Controller to open and draw fresh nutrient from the master reservoir. This automatically maintains the ideal nutrient level in all the interconnects units, simple, elegant, reliable and inexpensive.
Two Controller sizes are available, the eight gallon Controller plus eight gallon master reservoir; and the "Texas Controller" (it's big) which features a 20 gallon Controller Module with 20 gallon master reservoir.
The Controller requires a level area to work properly - all interconnected units must be set at the same altitude since water will always seek a common level.
