Who This Is For

  • You are upgrading your nursery setup because flimsy trays keep cracking under the weight of wet soil and heavy plugs
  • You are standardizing your rack system because inconsistent tray dimensions create uneven spacing and spills during transit

What We Found

  • The double-thick plastic removes the need to double-stack trays for structural support during transport
  • We suggest these for anyone who uses heavy vertical racking since the edges do not warp under weight

What Users Say

  • Users who transitioned from standard flats say they no longer deal with cracked corners after moving full loads
  • Growers report that the rigid base makes it easy to slide trays on and off wire shelves without snagging

SunBlaster Double Thick 1020 Propagation Tray

Are you tired of flimsy, single-use cultivation flats that warp, twist, and crack when filled with wet soil or heavy starter plugs? Standard propagation trays frequently fail during transport, causing root shock to delicate seedlings and creating messy spills in your clean indoor grow room. While this 2-inch deep model is perfect for general propagation, growers focused on shallow-rooted crops may prefer the SunBlaster double-thick microgreen tray for easier harvesting. The SunBlaster Double Thick Tray addresses this common nursery issue by providing a heavy-duty, reinforced framework that guarantees absolute stability when lifting and moving your plants.

Engineered to be twice as thick as traditional baseline 1020 flats, the SunBlaster Double Thick Tray provides professional-grade resilience that makes it fully reusable across countless propagation cycles. Measuring a standard 21.3" L x 11.0" W x 2.0" H, it fits cleanly onto standard vertical growing racks, wire shelving, and inside a SunBlaster 7 inch humidity dome. For consistent thermal control, many growers pair this tray with a SunBlaster Heat Sheet propagation mat and a digital heat sheet controller to maintain ideal root zone temperatures.

FAQ

What makes this tray different from traditional 1020 trays? +

This tray is manufactured with double the material thickness of conventional, thin retail plant flats. This extra reinforcement prevents the tray from flexing, buckling, or splitting down the center when loaded with heavy, damp media.

Is this double-thick propagation tray reusable? +

Yes, absolutely. While typical seedling flats are thin and quickly discarded after a single harvest cycle, this heavy-duty tray is explicitly engineered for long-lasting, multi-season reuse across multiple cloning and seeding cycles.

Will standard humidity domes fit properly onto this flat? +

Yes, this model preserves the exact industry-standard 1020 layout parameters. It is fully compatible with the SunBlaster Nano Humidity Dome, clear propagation covers, and interior multi-cell plug inserts.

What are the exact measurements of a single tray unit? +

Each individual tray measures 21.3 inches long by 11.0 inches wide with a wall height depth of 2.0 inches. This low-profile design fits cleanly onto vertical nursery racks, within the SunBlaster T5 Grow Light Garden, and other standard propagation setups.

Can I clean and sanitize this tray between growing cycles? +

Yes, its robust construction allows for thorough maintenance. You can safely wash, scrub, and apply mild horticultural sanitizing solutions to the tray surface between cultivation cycles to keep your nursery free of pathogens.
