The aeroponic AeroFlo generates a fine nutrient solution mist to maximize oxygen to the root zone and provide ideal growing conditions. 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. By controlling the depth of nutrient solution in the growing chamber, gardeners can maximize moisture supplied to seedlings and cuttings and increase aeration to the roots of mature plants. Measures 4'2"x 4'7". The 36-site unit comes with six 4' grow chambers, 36 3"net cups, 40-gallon reservoir, WaterPOWER 120 pump, sawhorse, Coco Cups, grow rocks and three-part Flora Kit.
