13 Gallon Reservoir and an 8-Gallon Controller Including all the Hardware Needed to Build Your Own System!

The Controller Complete is straight-sided and designed to accommodate up to 12 farm modules. It includes a 13 gallon reservoir, 8 gallon controller, tubing, fittings and float valve.

The Controller is very simple - a container with a float valve is connected to the line of units. A master reservoir filled with fresh water and 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 interconnected units, simple, elegant, reliable and inexpensive.

Controller Includes:

  • 13 Gallon Reservoir with Grommet Fittings
  • Blue 1/2" tubing
  • 8 Gallon Controller with Float Valve
  • Seven 1/2" Barbed Tees
  • Two 1/2" Elbows

Controller Dimensions: 12"W x 12"L x 3'6"H

Note: This Controller can accomodate up to 12 Farm modules maximum. Any more requires you to move up to the Texas Controller (

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.
