WHAT IS THE CONTROLLER, AND WHAT DOES IT DO?
The Controller is a large external nutrient reservoir, which can supply make-up nutrient to as many as eight WaterFarm or PowerGrower modules. It provides an additional supply of nutrient solution as the plants move into their rapid growth phase. The larger Texas Controller can be used to supply up to 12 WaterFarm or PowerGrower modules, or it can be used in conjunction with the RainForest or EcoGrower systems.
