What is it?
Air Pruning
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.

History of The Winstrip® Tray
The Winstrip nursery tray may have had the greatest positive impact on the nursery industry in recent times.
The Winstrip Tray is an invention by Aart Van Wingerden ("Win" strip) more than 25 years ago. Aart was from Holland where soil blocking was developed. His knowledge of the well known benefits of soil block air pruning was the basis for the design of the Winstrip Tray.
Research and development for The Winstrip was funded by The Van Wingerden Company; a $240 million horticultural powerhouse.
Winstrip manufacturing and trademark was transferred from Van Wingerden to Neversink Farm in 2017. Neversink Farm has stayed true to the proven design and high quality of The Winstrip used by countless farms and nurseries around the world for decades.

Benefits
Air pruning
Stronger Roots
No Over watering
Do not dry out as easily
Better Plant Survival
Healthier with Less Disease
Air Circulation Around Cells
Fast to fill
Air Pruning
The Large Wintrip Shape that extend across the bottom of the cell not only make it easy to remove starts but air prune the roots preventing root circling. Thus Transplants can be left longer in the tray if needed. Transplants are also healthier and grow quickly when transplanted.
Heavy Duty
Each tray weighs in at over 1.7 pounds. They stack and nest for easy storage. They are made with thick UV resistant plastic of the highest quality to last for many, many years. I have had mine for 10 years and they still work great.
Open Cell
Winstrips open cell design allows more air which creates a healthier environment. Each cell has vertical air spaces and strips where air can flow around each cell. More importantly these slits extend all the way to the bottom corners of the cell. This creates healthy starts with much less disease.

Bottom Trays?
Unlike regular flimsy vacuum formed nursery trays, Winstrips do not require a bottom tray for handling. Winstrips can be moved around easily with one hand as they are built thick and tuff.
For farm scale use in Greenhouses, Winstrip Trays can be used directly on vented tables to get the best air circulation. Winstrips provide airflow around every cell.
You can also use a bottom tray, like our indestructible trays, to water from below. Winstrips uniquely provide airflow from above and below, so even on bottom trays, there will still be a lot of air circulation around your seedlings.

Healthy and Fast
Seedlings are healthier because there is less disease due to added airflow. When planted they begin growing faster due to less transplant shock because of air pruned roots.
