General Hydroponics controllers are used anytime a larger reservoir is needed. As the plants draw water from their individual reservoirs, the controller replenishes the nutrient solution. A reservoir filled with fresh nutrient maintains proper water level in an attached float-valve actuated controller, connected to several growing units.
