Superoots Air-Pot Hydro is the version designed for indoor use. The reusable plastic pot whose unique structure actively enhances the quality of plant root systems. Made from recycled HDPE, Superoots Air-Pot is circular in shape, with a perforated wall that is designed like egg cartons. There are no flat surfaces that cause the roots to begin the spiraling process. The closed cones pointing inward cause the roots to head for the hole located at the end of the outer cones, where the root dehydrates. The plant's reaction to this pruning is to emit even more roots, leading to the development of a dense, fibrous radial root system in a very short time.
