SunBlaster Double Thick Tray

A Reinforced 1020 Tray Built to Outlast a Standard Flat

A standard 1020 propagation tray can crack or warp after repeated seasons of watering, stacking, and moving between growing areas, especially in a commercial setting running the same trays year-round. SunBlaster's Double Thick Tray uses twice the wall thickness of a traditional flat to hold up to that kind of repeated handling.

The added thickness helps the tray resist cracking and warping under regular use, making it a better fit for growers who reuse the same trays season after season rather than replacing them annually.

Key Features & Benefits

• Double the Wall Thickness — of a traditional 1020 tray, for added rigidity under handling.
• Standard 10x20-Inch Footprint — matches common 1020 racking, shelving, and dome sizing.
• Built for Repeated Reuse — designed to withstand seasons of watering and handling rather than one-time use.
• Pairs With a 7-Inch NanoDome — combine with SunBlaster's vented NanoDome for a complete propagation setup.

Who Should Use This Tray

This tray fits growers who reuse the same trays across many growing cycles rather than replacing them each season, including commercial propagation operations standardizing on a single tray depth across their racking.

About SunBlaster

SunBlaster builds propagation trays, domes, and grow lighting from its base in Langley, British Columbia, sizing its tray line to the 10x20-inch format used throughout the greenhouse industry so its trays and domes interoperate with standard racking and other manufacturers' 1020 equipment.

Frequently Asked Questions

How much thicker is this than a standard 1020 tray?

This tray uses double the wall thickness of a traditional 1020 propagation tray, which adds rigidity and resistance to cracking under repeated handling. It's a step up from a standard tray without going to the four-times-thickness of SunBlaster's Quad Thick line.

Can I reuse this tray across multiple grow cycles?

Yes, the added thickness is meant to let the tray withstand repeated watering, moving, and handling across many cycles rather than being treated as disposable after one use. Rinsing and sanitizing between crops helps avoid carrying over pathogens from one planting to the next.

What dome fits on top of this tray?

A 7-inch SunBlaster NanoDome with vents is sized to pair with this tray for a complete propagation setup, though the tray also works on its own or with other standard 1020 domes. The dome and tray are sold separately.

Does this tray have drainage holes?

No, this standard Double Thick tray does not include drainage holes, so it retains applied water and nutrients in the growing media rather than letting them drain through. Growers wanting drainage should look at a vented tray or dome instead.
