Hydrofarm Active Aqua Grow Flow Ebb u0026 Gro 12 Site 2gal Hydroponic System GFO7KT

Active Aqua's Grow Flow is the most efficient ebb & flow system on the market. The fill and drain cycles are maintained by the controller unit and set with the built-in timer. This system can be set up in many different sizes and shapes to fit your exact growing needs. Grow Flow is the only unit on the market with fail-safe overflow protection. If the float valve stops operating the emergency shut-off valve will automatically power down the system preventing any spillage or damage to your growing area. At the same time the LED indicator light will light up on the control panel. Since your pumps are only pumping a short time each day the system is extremely reliable and efficient. The main controller bucket has adjustable fill height and an emergency shut-off valve. Grow Flow controller units and buckets are also available separately.
