SunBlaster Double Thick 1020 Seedling Tray – With Drainage Holes

Durable Double‑Thick 1020 Propagation Tray With Drainage Holes

The SunBlaster Double Thick 1020 Seedling Tray is a professional‑grade propagation flat built to outperform standard trays. Molded from thick, heavy‑duty plastic, this tray resists warping, cracking, and collapse - ensuring many growing cycles of reliable use.

Measuring 10″ × 20″ (standard 1020 size) with roughly 2½″ (≈6 cm) depth, it provides ample root space for seedlings, cuttings, microgreens, herbs or any propagation needs. Drainage holes ensure excellent water flow and prevent root rot, while the robust tray wall and bottom construction handle heavy media and repeated reuse.

Designed for growers who demand durability and consistency. Compatible with humidity domes, heat mats, and standard greenhouse shelf or bench systems. Perfect for soil, coco, or seed‑starting media - from home growers to commercial operations.
