Who This Is For

  • You are upgrading your nursery setup because flimsy flats keep leaking and buckling when you move heavy plant material
  • You are switching to rigid propagation trays because you need perfectly level surfaces for consistent water distribution

What We Found

  • These are four times thicker than standard flats, so they stay stiff even when you lift them with one hand
  • We recommend these over double-thick versions if you handle heavy loads like wet rockwool or dense microgreens

What Users Say

  • Growers who swapped to these trays report they stopped losing harvests to bent flats during transport
  • Operators who run daily wash cycles say these do not crack or warp like the cheaper retail versions

SunBlaster 1020 Quad Thick Tray | 5-Pack

Are you frustrated with flimsy retail seedling flats that bend, leak, and split under the weight of wet soil or damp rockwool? Standard trays often buckle during transport, causing root damage and messy spills across your nursery shelves. The SunBlaster 1020 Quad Thick Tray eliminates these costly structural failures and pairs perfectly with a SunBlaster Heat Sheet Propagation Heating Mat for stabilized seedling growth and exceptionally rigid support.

Engineered to be four times thicker than traditional propagation flats, the SunBlaster 1020 Quad Thick Tray delivers professional-grade durability that lasts for countless production cycles. Its robust walls prevent twisting when lifted with one hand, making it a more durable alternative to the SunBlaster Double Thick 1020 Propagation Tray for heavy commercial operations and demanding crops like microgreens or wheatgrass. This 5-pack allows you to stagger production cycles, protect your delicate root zones, ensure flat and level water distribution, and dramatically lower your long-term operational overhead.

FAQ

What exactly does "Quad Thick" mean? +

This premium propagation tray is manufactured to be four times thicker than standard, single-use retail 1020 flats. This heavy-duty structural profile prevents the tray from buckling, warping, or cracking when handling heavy wet soils or dense root mats.

Is this 5-pack a good value for commercial operations? +

Absolutely. Having five trays on hand lets you stagger planting cycles for continuous harvests at different stages of maturity. Combined with the quad-thick construction that survives repeated washings and sanitation cycles, this pack dramatically lowers your per-unit cost over time.

Can I reuse these trays for multiple growth cycles? +

Yes, absolutely. Unlike cheap seedling flats that must be discarded after a single harvest, this ultra-durable model is engineered to withstand years of repeated washings, sanitation protocols, and rigorous commercial use.

Will standard humidity domes sit securely on this base? +

Yes, it utilizes a classic greenhouse industry-standard 1020 exterior footprint. It is built to seamlessly pair with the SunBlaster Nano Humidity Dome 7" with Vents as well as most other traditional starter lids on the market.

What are the exact dimensions of a single tray? +

A single tray unit measures approximately 21.3 inches long by 11.0 inches wide with a vertical wall depth of 2.5 inches. This ensures it slides cleanly into standard vertical grow racks, wire shelves, and nursery tables.

Is this tray suitable for commercial microgreen production? +

Definitely. Because it maintains a completely rigid, level surface, it is a favorite among professional microgreen and wheatgrass farmers. It allows you to lift and transport packed trays safely with one hand, and it works excellently as a base for a SunBlaster Double-Thick Microgreen Tray w/Holes.
