Winstrip® Air Prune Nursery Trays have been trusted by growers around the world for decades. They are simply the best, longest lasting trays made and they are guaranteed.
The Winstrip Tray eliminates over watering, reduces disease, and produces the highest quality seedling that resists transplant shock. This is achieved through air strips and open cells.
Air Pruning
Roots obviously grow downward. Every nursery tray has only a round drainage hole at the bottom of the cell. Roots hit the bottom of the tray and circle around and around that hole.
The Winstrip Trays' unique bottom design stops roots from circling even if the plant is overgrown. It is all about that Winstrip shape at the bottom of the cell. It holds in soil and air prunes.
