This 3 gallon equivalent Superoots Air Pot is excellent for transplanting seedlings and cuttings. Plants can be kept for one to two seasons before transplanting into a larger pot, or directly in the garden. This Air Pot will accommodate a 2' to 6' plant. The Superoots Air Pot is a recyclable, reusable plastic container that actively enhances the quality of the root systems of plants. This revolutionary approach to containerizing plants and trees produces fabulous, non spiraling root systems that are impossible to develop in any other available container. Made of recycled HDPE in the UK, the Superoots Air Pot is circular in shape with a perforated sidewall. There are no flat surfaces due to the inward and outward pointed cones, which eliminates any chance of starting the spiraling process as well as dramatically increases growth rates.
