What is it?
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
The Winstrip 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 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.
"Switching to Winstrip Trays had the biggest affect on my farm's production compared to all the changes we have made at Neversink over the years." -Conor Crickmore

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, Winstrips should be used on vented tables to get the best air circulation. Winstrips provide airflow around every cell and bottom trays would interfere with that functionality.
If you are starting seedlings in your house and want to protect furniture and floors or just like to bottom water. Winstrips uniquely provide airflow from above and below, so bottom trays will still allow air around your seedlings. Thus, you will still get most of the benefits and with Winstrips' open cells, watering is a breeze. Many home gardeners use our trays with bottom trays. Photo: @texasecofarms
