The #1 Air-Pot® is a great starter pot for seed germination and cuttings. Plants can be kept for one season before planting in the garden. For indoor use, the #1 Air-Pot will accommodate a 2- to 4-foot plant and can accommodate a full term growth cycle. The Air-Pot container design guarantees healthy root development by allowing for additional oxygen in the growing medium, leading to healthy bacteria and better release of nutrients to the plant. The shape of the walls eliminate root circling and encourage the development of a mass of healthy fibrous roots. Constructed from durable recycled plastic, Air-Pot containers can last 10 years or more.
