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.
