Air Pot® #12 containers, AKA 12 gallon Air Pots, provide outstanding root-zone aeration for soil, coco fiber, and hydroponic applications. Constructed of durable recycled HDPE with contoured and perforated sidewalls like all Superoots containers, the 12 gallon Air Pots provide ideal root growth conditions and prevent root spiraling or root binding for the best growth possible. Although the #12 Air Pots hold approximately the same amount of medium as a conventional 12-gallon container, their specialized design actually permits the growth of larger plants thanks to the superior root structure they produce. With extra room for growth, #12 Air Pots are the best choice for space demanding plants including shrubs and even trees. Maximize your root growth and development with contoured and perforated sidewalls. Air Pots assemble quickly and easily with included base and screws, no tools needed. Size: 38L /10 Gal.
