The Air Pruning Tray
Winstrip® is a registered trademark of Neversink Tools
Made in the USA by us from food grade BPA-free recycled plastic
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 combined with AIRSTRIP technology 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.

Why Our Trays are Black
Colored nursery trays can be appealing, but they break down quickly under prolonged sunlight. Our trays use carbon black, which provides the best UV protection and allows them to withstand professional use for more than 30 years. Because our focus is on durability and long-term value for professional growers, offering brightly colored trays would be inconsistant with who we are as a company.
Air Pruning
The Large Winstrip 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.
Lifetime Use
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 20 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 Airstrips 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?
Bottom trays are a great addition to water Winstrips from below. Our indestructible trays are the best made.
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.
For farm scale use in Greenhouses, Winstrip Trays can be used directly on vented tables to get the best air circulation.

Winstrip Frequently Asked Questions
Winstrip trays use an open cell and bottom design that exposes root tips to air as they reach the edges and bottom of the cell. This helps stop roots from circling and encourages a more branched root system.
Avoid relying on trays that have a round drainage hole at the bottom of each cell. Roots can reach the bottom and continue growing around that opening instead of being consistently exposed to air. Effective air-pruning trays expose more of the cell edge and bottom to air so root tips are pruned as they reach those surfaces.
Winstrip trays are available in 50, 72, 128, 200, and 288 cell layouts. Larger cells such as 50 and 72 are commonly used for larger or longer-grown transplants, while 200 and 288 trays save greenhouse and germination-chamber space for high-production crops or varieties that will be potted on. Choose based on crop size, how long the plant will remain in the tray, and your transplanting workflow.
No. Winstrip trays are rigid enough to handle without a bottom tray. A bottom tray is optional and is useful for bottom watering, drainage, or carrying. For maximum air circulation in farm-scale greenhouse use, Winstrip trays can also be placed directly on vented benching.
Yes. Use a Solid Indestructible Bottom Tray beneath the Winstrip tray for bottom watering. A Vented Indestructible Bottom Tray can be nested inside a Solid tray when you want extra drainage and to help keep plugs from sitting in water.
Yes. Their rigidity and the ability to pop plugs from the cells make Winstrip trays well suited to mechanical transplanting workflows.
Choose the board that matches the tray cell count: 50, 72, 128, 200, or 288. The 72-cell board also fits the Floret Winstrip 72 Deep Tray.
For plug removal from 200- and 288-cell Winstrip trays, use the matching 200 or 288 Dibble Board & Plug Popper together with the Winstrip Popping Frame. The frame supports the tray while the plugs are pushed out from below.
Some other 1020-format trays may fit for dibbling, but tray dimensions vary by manufacturer. Confirm the cell spacing and tray dimensions before use. Flimsy 1020 trays may not be suitable for plug popping.
The air-pruning design helps prevent the root circling that commonly occurs in conventional nursery cells. That gives growers more flexibility when seedlings need to remain in the tray longer before transplanting.
