The Air-Pot Propagation is the perfect way to germinate seedlings or for potting cuttings. Cuttings are ready to transplant within 2 to 3 weeks. Plant directly in the garden or any size Air-Pot up to the #15, depending on the size of plant and grow cycle you desire. Plants will not suffer transplanting shock. <br /><br /> 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. Toughly constructed from recycled plastic Air-Pot containers can last 10 years or more.
