General Hydroponics has taken the popular PowerGrower and incorporated the latest hydroponics technology to introduce the new and improved PowerGrower Eco. This single-chamber system uses a porous drip ring to efficiently deliver oxygenated nutrient solution to the root zone of several small- to medium-sized plants or one large specimen. The hexagonal shape of the PowerGrower Eco also makes it easy to fit into most any space and is particularly beneficial when arranging multiple units together. Measuring 15" across the top and 15" tall, system includes 5.7-gallon reservoir, air pump, Hydroton growing medium, and Flora nutrients. Check out the Controller to connect multiple Power Growers.
