The Air-Pot is a recyclable, reusable plastic container that actively enhances the quality of the root systems of plants. The inward pointing cones direct the root towards the hole in the outward pointing cones where the air density in the soil is too great and therefore the apical cells at the very tip of the root dehydrate, or are air-pruned. The response of the plant to this air-pruning is to send out more roots to compensate for the loss, which leads to the build up of a dense and fibrous radial root system in a dramatically short time.
Now Air-Pot is available in nursery equivalent sizes to simplify your size selection. If you are currently using a 5 gallon nursery pot, you can switch to the #5 Air-Pot (comparable in overall size, yet less actual volume, less soil needed with superior results.
