The Winstrip® Dibble Board & Plug Popper performs two jobs with one full-tray tool:
- Creates consistent planting dimples across an entire Winstrip tray in one motion
- Pushes finished plugs up from below for faster transplant removal
The board is injection molded as one integrated piece rather than assembled from individual dibbles, creating a stiff, durable tool for repeated propagation use.
COMPATIBILITY
Choose the board that matches your Winstrip tray cell count:
- 50: Winstrip® 50 Cell Tray
- 72: Winstrip® 72 Cell Tray and Floret Winstrip® 72 Deep Tray
- 128: Winstrip® 128 Cell Tray
- 200: Winstrip® 200 Cell Tray
- 288: Winstrip® 288 Cell Tray
200 & 288 TRAYS
For plug removal, pair the matching 200 or 288 Plug Popper with the Winstrip® Popping Frame. The frame supports the tray while the plugs are pushed out from below.
OTHER 1020-FORMAT TRAYS
Some 1020-format trays may fit for dibbling, but dimensions vary by manufacturer. Confirm tray dimensions before use. Flimsy 1020 trays may not be suitable for plug popping.
CENTER-TO-CENTER DIBBLE SPACING
- 50: 50.2 mm
- 72: 42.2 mm
- 128: 31.4 mm
- 200: 25 mm
- 288: 21.2 mm

Popping
Popping
Easily and quickly prepare seedlings for planting by popping them from the tray.
Popping eliminates the normal tearing of roots when seedlings are pulled from trays
Confirm Tray Fit
Works with 1020 Trays
Use these measurements to confirm whether a non-Winstrip 1020 tray will fit. 1020 tray dimensions vary by manufacturer.
Cell count — center-to-center spacing — dibble diameter
- 50 cell — 50.2 mm center-to-center — 15.8 mm dibble diameter
- 72 cell — 42.2 mm center-to-center — 12.9 mm dibble diameter
- 128 cell — 31.4 mm center-to-center — 10 mm dibble diameter
- 200 cell — 25 mm center-to-center — 7.5 mm dibble diameter
- 288 cell — 21.2 mm center-to-center — 5.9 mm dibble diameter
Center-to-center means the distance from the center of one cell to the center of the next cell.
Dibble
Dibble
Dibbling improves germination by making sure all seeds will get moisture. Depth of dibble is determined by pressure placed on dibble board.

Dibbles are molded with a premium clear UV blocking composite that will last many years. If dropped or banged against a hard surface the boards or dibbles will break. It is important to treat them with care.
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.
