With the Grow Waft’s easy-to-program controller unit, You’ll pretty much “set it and omit it.” And since your pumps are only pumping a short time on a daily basis, the system is extremely reliable and efficient. Just set the fill and drain cycles, and the controller unit does the rest! As for safety, the Grow Waft is the only unit available with fail-secure overflow protection. If the drift valve stops operating, the LED indicator lights up on the keep watch over panel and the emergency shut-off valve automatically shuts down the system, preventing any spillage or damage to your growing area. Have bigger plans? With the convenient included Grow Waft Expansion Kits You’ll connect up to 24 growing modules to a single 5-gallon system and up to 48 modules with the 2-gallon system! You’ll also build your own system from the ground up by purchasing all of the components individually. This high-quality 55-gallon drum is black in color and comes with a pre-drilled solid cover and bolt ring closure. It is perfect for use as a reservoir for larger hydroponic systems. The pre-drilled holes can be used for the grommets and barbed fittings necessary to outfit the drum with tubing for filling and draining. A larger hole can also be cut in the cover to act as a port for adding nutrients, checking pH, etc. Pair this drum with the included Active Aqua Grow Waft accessories to create the most efficient ebb & Waft system available on the market.
