The ultimate foundation to a “DIY” system
Create a low-maintenance garden with General Hydroponics Controllers. Simple, reliable and inexpensive, General Hydroponics Controllers consists of two connected reservoirs that help to ensure an ideal nutrient level is maintained in hydroponic systems. The Controller is the reservoir that sits on the bottom and has a float valve connected to a line of growing units. The Master Reservoir sits on top of the Controller and holds additional nutrient solution. As plants draw water from their individual reservoirs the liquid levels drop causing the float valve in the Controller to open and draw fresh nutrient solution from the Master Reservoir above. This automatically maintains the ideal nutrient solution level in all the connected units.
