1020 Double Thick 1.25" Deep Microgreen Tray

A Shallow Tray Built for Cutting Microgreens Close to the Base, No Holes

Cutting microgreens close to the media surface is easier in a shallow tray than in a standard 1.5- to 2-inch-deep propagation tray, where the extra depth puts more distance between the blade and the growing base. SunBlaster's Double-Thick Microgreen Tray is a shallow, 1.25-inch-deep tray built to nest inside a Double or Quad Thick standard 1020 tray, holding growing media at a height that makes harvest cuts closer to the base and improves presentation.

This no-holes version retains all applied water and nutrients in the growing media rather than letting it drain through, which suits growers using consistent bottom-up watering or wanting full control over moisture levels.

Key Features & Benefits

• 1.25-Inch Shallow Depth — positions media closer to the cutting line for a cleaner harvest at the base.
• Standard 10x20-Inch Footprint — matches the greenhouse-industry-standard 1020 size used across most trays and racking.
• Nests Inside Double and Quad Thick Trays — fits inside SunBlaster's deeper 1020 trays for added support during handling.
• Vacuum-Molded Construction — a manufacturing process suited to producing consistent, food-safe tray shapes.

Who Should Use This Microgreen Tray

This tray fits growers cutting microgreens for market or kitchen use, as well as anyone using a shallow flat as a seed-starting tray rather than a full-depth propagation tray. It works for a single home tray or as part of a larger stack of trays in a commercial microgreen operation.

About SunBlaster

SunBlaster manufactures propagation hardware, including trays, domes, and grow lighting, alongside its lighting lines, from its base in Langley, British Columbia. The microgreen tray line is sized to the same 10x20-inch industry standard as the company's deeper Double and Quad Thick trays, so growers can mix and match tray depths within the same rack.

Frequently Asked Questions

Should I choose the version with holes or without?

The version with drainage holes lets excess water pass through to a tray or dome underneath, which suits growers watering from above or wanting extra runoff control. The version without holes retains all applied water and nutrients in the media, which some growers prefer for consistent bottom-up watering setups.

How do I use this tray with a Double or Quad Thick tray?

Set the shallow microgreen tray inside a Double or Quad Thick standard 1020 tray, which acts as a sturdier outer shell during watering, moving, and stacking. The shallow tray holds the growing media and seed, while the outer tray manages handling and any drainage.

Why use a shallow tray instead of a standard-depth propagation tray for microgreens?

A shallow, 1.25-inch tray puts less media between the harvest blade and the tray bottom, which lets growers cut closer to the base for a cleaner, more presentable harvest. A deeper standard tray works fine for seedlings transplanted later, but adds unnecessary depth for a crop that's cut, not transplanted.

Can this tray be reused across multiple growing cycles?

Yes, the vacuum-molded construction is built to be washed and reused rather than treated as disposable. Clean it between crops to reduce the risk of carrying over mold or pathogens from one planting to the next.
