The Air-Pot U is a continuous suspended trough of Air-Pot material for the cultivation of small trees and shrubs. The height of the Air-Pot U above the ground makes the trees much easier to work with, in any weather, and greatly reduces the need to use fungicides and pesticides. Irrigation and delivery of nutrients are built into the system and runoff can be collected for recycling.

The U system is used in conjunction with a filling and harvesting machines for extremely efficient production. The Air-Pot material is pulled from the frame and the trees separated as they come off. Growing in the Air-Pot U ensures the development of a healthy non- spiralling root system, leading to better uptake of nutrients and water, faster growth and healthier plants.

The improved root structure allows the trees to establish instantly in the next stage of their development. Transplanted after a year in the U, trees have put on up to 50% more growth than the same species transplanted from the field. Ready for sale in two rather than three years.
