D20T Support Tray with 20 Deepot Cells

This propagation system is designed to raise deep-rooted seedlings with strong, transplant-ready root architecture. The D20T Support Tray pairs with 20 Deepot cells to guide roots downward, reducing circling and encouraging a straight taproot. Each cell measures 2.7" in diameter by 14" deep, seated in a sturdy 12" x 14.8" support tray with a total height of 9.4" for stable handling on benches and in nurseries.

Deep cells promote vigorous root development for fruit trees, native trees, shrubs, and perennials that appreciate extra rooting depth. The vertical form improves drainage and aeration so media stays evenly moist without waterlogging, which helps limit damping off and transplant shock. The tray keeps cells organized for bottom watering, labeling, and easy movement from greenhouse to hardening area. With careful cleaning between cycles, this reusable setup supports sustainable propagation and reduces single-use plastic in the garden or small farm.

For best results, fill with a well-draining propagation mix, dibble a planting hole, and sow or set cuttings at the recommended depth. Maintain even moisture and moderate fertility, then harden off seedlings before field planting. When it is time to transplant, the long cell shape makes it simple to slide out a cohesive root plug that establishes quickly in beds, orchards, or restoration sites.
