Roots obviously grow down and in every nursery tray there is only a round drainage hole at the bottom of the cell. Roots hit the bottom of the tray and circle around the edge and around that hole. A circle on the bottom means circling roots.
The Winstrip tray doesn not have a circle on the bottom, rather it has a strip that extends across the entire bottom of the cell and slits on the sides that reach the opposite corners of tray. These features air prune the roots. The root try to circle but hits the air in those corners and stops. The root then gets strong as is waits to be transplanted.
It is all about that Winstrip shape at the bottom of the cell. It holds in soil and air prunes.
