SUNPACK Propagation Tray - 10in x 20in - Black

Standard-Drainage 1020 Propagation Tray in Food-Grade Black Plastic

The SUNPACK Propagation Tray in Black is the standard-drainage answer to a full 1020 bench: food-grade, BPA-free virgin plastic molded to 21.25in L x 10.81in W x 1.29in H, with reinforced sides and lips for carrying a fully loaded tray without the edges giving way. Deep-channel bottom ridges run the length of the tray, lifting containers slightly off the floor for drainage and airflow rather than letting them sit in standing water.

Black plastic absorbs ambient heat, giving the root zone a small warmth advantage over a reflective tray color, while also cutting down on the algae growth that thrives in a lit, damp tray floor. This is the tray most growers reach for by default when no specific reason points them toward a white, no-drain, or specialty format instead.

Key Features & Benefits

• Food-grade, BPA-free virgin plastic — Safe for use with vegetables, herbs, and other edible crops throughout propagation and early growth.
• Standard 1020 dimensions — 21.25in L x 10.81in W x 1.29in H fits standard propagation bench systems, greenhouse racks, and compatible inserts.
• Reinforced sides and lips — Extra structural strength at the edges makes the tray easy to carry safely when fully loaded with plants and media.
• Deep-channel bottom ridges — Promotes drainage, prevents waterlogging, and keeps containers stable and elevated for better airflow.
• Black color — Absorbs heat to warm the root zone slightly and reduces algae growth in the tray floor.

Who Should Use This

This is the default choice for greenhouse growers, nursery operators, and home gardeners who need a durable, food-safe drainage tray for seed starting, seedling production, or plant transport, without a specific reason to choose the white, no-drain, or heavier-duty alternatives in the SUNPACK tray line.

Compatibility

Standard 1020 size compatible with SUNPACK and most other-brand 72-cell and 50-cell inserts, Jiffy pellet trays, and other standard 1020 propagation inserts. Works with overhead and flood irrigation systems; the deep-channel ridges accommodate drainage from inserts placed above.

Frequently Asked Questions

Is this tray food-grade and BPA-free?

Yes, SUNPACK propagation trays are made from food-grade, BPA-free virgin plastic, making them safe for use throughout the propagation and early growing stages of edible crops. That certification covers herbs, vegetables, and other food crops grown directly in the tray or in inserts placed above it.

What are the tray dimensions?

The tray measures 21.25in L x 10.81in W x 1.29in H, standard 1020 size compatible with U.S. and Canadian market propagation inserts and bench systems.

Why do the bottom ridges matter for drainage?

The deep-channel bottom ridges allow water to drain freely away from container bases while providing stable, level support for inserts and pots placed directly in the tray. Without them, containers would sit in whatever runoff collects on the tray floor.

How many growing seasons will this tray last?

SUNPACK trays are constructed from thick, premium plastic designed for multi-season use. With basic care and proper storage, they hold up reliably through many growing cycles.

When would I choose this tray over the White No-Drainage version?

Choose this Black drainage version for standard bottom-watering or overhead-watering setups where excess water should exit the tray. Choose the White No-Drainage tray instead when you specifically need a solid reservoir for sub-irrigation or ebb-and-flow systems.
