The #7 Air-Pot® is the perfect size for growing larger plants for at least two years. The #7 Air-Pot will accommodate a 2- to 6-foot plant. To continue growing in the pot past the second season, just keep watering and fertilizing as required. The root system will continue to flourish and will produce abundant foliage. 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.
