RooTrimmer 1020 Nursery Trays, 5-Pack 21.6×11.2×2.52 in — BPA-Free Reinforced No-Hole Seedling Trays

RooTrimmer 1020 plant trays are durable, hole-free plastic nursery trays sized for standard 10×20 plug systems, ideal for microgreens, seed starting, and bulk transplanting.

These RooTrimmer trays measure 21.6"×11.2" at the rim with a 10"×20" bottom and a 2.52" depth, sold in packs of five. Constructed from thick, BPA-free polystyrene with reinforced walls, each tray is designed to resist bending and hold ample soil for seedlings or microgreen beds. Because they do not have drainage holes, they work well for controlled watering setups, humidity domes, and hydroponic-style sprouting where water retention is desired.

How do these trays fit standard seedling and microgreen systems?

The RooTrimmer trays are built to the 1020 standard footprint so they pair easily with common plug trays, propagation domes, and shelving. Their top rim and bottom measurements align with most commercial inserts and trays used in greenhouses and DIY setups.

• Standard bottom: 10"×20" — fits 1020 plug trays and inserts.
• Outer rim: 11.2"×21.6" — stacks and nests reliably on racks.
• Depth: 2.52" — provides sufficient soil volume for seedlings and microgreen roots.

What construction and materials make these trays durable?

Each tray is molded from BPA-free polystyrene at a reinforced 1.8mm thickness that increases rigidity compared with thinner hobby trays. The heavier weight and stiffer walls reduce twisting under load and make them suitable for moving full trays without sagging.

• Material: BPA-free PS for safe horticultural use.
• Thickness: 1.8mm reinforced walls for strength.
• Weight: approximately 277g per tray for stable handling.

Why choose trays without holes, and how can I use them effectively?

Hole-free trays retain moisture and are easier to use with capillary mats, bottom-watering, or when starting microgreens that prefer even moisture. They also work well as liners inside larger bins or for temporary transport and bulk soil mixing when drainage control is needed.

• Best for bottom-watering and capillary systems to reduce surface evaporation.
• Works under humidity domes for germination and sprouting.
• Good for holding soil during plug tray fills or nursery pot transfers.
