Heavy Duty Cut Kit Tray, 21.3 x 11.0 x 2.8 in, Reinforced

Hydrofarm Heavy Duty Cut Kit Tray — Reinforced, UV Protected, 21.3 x 11.0 x 2.8 in

Standard propagation trays are fine for occasional use, but commercial operations and serious home growers put trays through a lot — repeated loading with wet media, stacking, cleaning, and handling can cause standard trays to warp, crack, and break down faster than expected. The Hydrofarm Heavy Duty Cut Kit Tray is built for this kind of sustained use, with thicker plastic walls, reinforced sides and lip, and UV protection for extended service life.

At 21.3 x 11.0 x 2.8 in and 1.8 mm wall thickness, the CKTRAYHD is more rigid and more resistant to bending under load than standard-gauge trays. No holes — the watertight base allows it to function as a drainage catch tray or bottom-watering reservoir, just like the standard CKTRAY. Pairs with the Hydrofarm mesh tray (CKMESH2) for mess-free cube draining.

Key Features & Benefits

• 1.8 mm wall thickness — thicker than standard trays — reduces bending, warping, and cracking under repeated load.
• Reinforced sides and lip — structural reinforcement at the edges adds rigidity and extends the life of the tray through repeated handling.
• UV protection — UV stabilizers protect the plastic from degradation caused by prolonged light exposure in grow rooms.
• No holes — watertight — solid base for drainage containment or bottom watering.
• Dimensions: 21.3 x 11.0 x 2.8 in — slightly deeper than the standard CKTRAY for added water holding capacity.

Who Should Use This Tray

Commercial propagation operations, professional growers, and high-volume users who need seed flats that hold up under the demands of continuous-use propagation — where standard trays warp, crack, or fail prematurely.

Why UV Protection Matters in Indoor Grow Rooms

Modern LED grow lights emit significant UV output — and standard plastic can degrade over time when exposed to repeated UV light cycles. UV-stabilized plastic, like that used in the CKTRAYHD, resists this degradation, maintaining its structural integrity and color stability over a longer service life. For facilities that run lights for 16-20 hours per day year-round, UV protection is a meaningful specification in propagation equipment.

Frequently Asked Questions

What is the difference between this and the standard CKTRAY?

The CKTRAYHD has thicker walls (1.8 mm vs. standard gauge), reinforced sides and lip, UV protection, and slightly larger outer dimensions (21.3 x 11.0 x 2.8 in vs. 21 x 11 x 2.5 in). It is designed for heavy commercial use where standard trays would wear out prematurely.

Does this tray have drainage holes?

No. The CKTRAYHD is a solid, no-holes watertight tray — suitable as a drainage catch or bottom-watering reservoir.

What inserts fit this tray?

Compatible with standard 10 x 20 in flat inserts. The slightly larger outer dimensions mean the tray can accommodate the same insert lineup as the CKTRAY.

Does UV protection affect plant growth?

UV stabilizers in the tray plastic do not affect light transmission to plants — they only protect the tray itself from UV degradation. The tray does not cover the growing area.

How should I clean this tray?

Rinse with water after each use. For sanitizing between cycles, diluted hydrogen peroxide or commercial propagation tray cleaner is recommended. The heavy-duty construction withstands regular cleaning without warping.
