The unique hexagonal shape of the PowerGrower enables growers to place units close together when plants are small and then separate them as the plants grow larger. The The PowerGrower comes in two forms, Complete or Modular. The Complete PowerGrower is designed to be a stand alone system with 2 gallon growing chamber, 4 gallon reservoir, and includes an Elite air pump, clay pebbles, farm kit and Flora Series nutrients. The Modular PowerGrower is designed for multiple unit configuration with a GH Controller. Both PowerGrower models can be staked with PVC piping to support larger plants.
