If you want to take your hydroponics gardening to a higher level, the WaterFarm 8-pack is a good choice. It's been around over 25 years and has a proven track record! 

The WaterFarm 8-pack is eight WaterFarm module units connected to one General Hydroponics Controller with a 13 gallon reservoir and an 8 gallon controller unit. The Controller automatically keeps each top-feed drip module filled with the proper level of nutrient solution, making this a low maintenance growing system.

Each 1' x 1' WaterFarm module can support 1 large plant, or up to 5 small plants. The square shape lets you crowd the modules together for a compact growing area. Once your plants mature into larger sizes, simply move the modules apart to add growing room.

The WaterFarm 8-pack increases oxygen and nutrients to the plant roots for a more vigorous, healthier garden.

Comes complete with dual diaphram air pump, hardware, connectors, and detailed instructions.

Does NOT include Hydroton. Be sure to order separately if needed.
