SOLIGT Extra Thick 1020 Seed Starting Trays 10 Pack - Heavy Duty No

Our review of the SOLIGT Extra Thick 1020 seed starting trays finds them ideal for gardeners who start many seedlings and need sturdy, reusable flats. The single biggest reason to buy is their heavy-duty, no-hole construction that keeps soil and water contained while allowing bottom watering and clean transport. These trays suit microgreens, transplant flats, and general seed starting where durability and repeated use matter more than built-in drainage.

Key Features

• 10 pack convenience: Having ten identical trays makes it easy to separate seed varieties, label trays, and run multiple batches at once without cross-contamination.
• Extra thick heavy duty material: The durable plastic resists buckling even when filled with soil or multiple pots, so trays hold shape through handling and reuse.
• No holes, no leakage: The solid base prevents spills and keeps surfaces clean while enabling bottom watering and better root moisture uptake.
• Standard 1020 outer dimensions: At roughly 21 by 10 3/4 by 2 1/2 in they fit common heat mats, domes, and shelving, helping maintain uniform spacing in a grow area.
• Versatile compatibility: These flats work with soil blocks, cell inserts, peat pots, and hydro setups, making them useful across many seed starting systems.

Who It's For

These trays are best for hobby and experienced gardeners who start seeds regularly, run multiple varieties, or grow microgreens and transplants indoors or in a greenhouse. The set is particularly useful when you want durable, reusable trays that tolerate frequent handling and can support pots or soil blocks without sagging.

They are less suitable for growers who prefer tray designs with built-in drainage or who exclusively use single-use biodegradable containers; if constant drainage control is required, a tray with holes or a different irrigation setup may be a better fit.

Pros & Cons

Pros

• Sturdy construction provides long-term reuse and holds heavier loads without buckling.
• No-hole design prevents leakage and keeps bench and floor areas cleaner during bottom watering.
• Ten identical trays simplify organization, labeling, and running multiple seed batches.

Cons

• Some customers mention the trays can be narrow compared to other 1020-style trays, so fit should be verified for specific pot layouts.
• Plastic trays require manual separation and handling; a few users report difficulty separating tightly stacked pieces.
