The General Hydroponics® AeroFlo® comes complete with everything to get started and offers the fastest growth rate of any hydroponic system we sell. By generating a fine mist of nutrient solution, aeroponic culture optimizes the oxygen-water-nutrient ratio for the roots of plants and provides ideal conditions for all stages of growth. Plants roots grow in the moist air space between the net cups and hang in a shallow, constantly circulating bath of super-oxygenated nutrient solution. Controlling the depth of nutrient solution in the growing chamber maximizes moisture supplied to seedlings and cuttings and increases aeration to the roots of mature plants. Measures 2 feet by 5 feet and 2 inches. This 18-site unit includes 17-gallon reservoir, three 4-foot grow chambers, WaterPOWER 120 pump with injection manifold, support structure, 3-inch grow cups, CocoTek Coco cups and clay pebbles, and three-part Flora Kit.
