T.O. Plastics Standard 1020 Germination Tray - 10.81in × 21.25in × 1.29in - No Holes - 100-Pack

Low-Profile Germination Tray for Seed Starting, No Drainage Holes

Seed starting needs consistent surface moisture more than it needs drainage, which is the opposite priority from a tray built for established transplants. T.O. Plastics' Standard 1020 Germination Tray skips drainage holes and uses a low 1.29-inch profile specifically for that early seed-starting stage, holding moisture at the surface rather than letting it drain straight through.

At 241.59 cubic inches of capacity (133.12 fl oz), this tray holds enough water or solution to support a full germination cycle across a standard 1020 footprint, shipping 100 per case.

Key Features & Benefits

• No drainage holes — holds moisture at the surface for consistent seed germination rather than draining it away.
• Low 1.29in profile — matches the shallow depth germination trays typically need compared to transplant trays.
• 241.59 cu in capacity (133.12 fl oz) — holds enough liquid for a full germination cycle.
• 100-pack case — supports outfitting a full germination run in one order.

Who Should Use This Tray

This fits growers starting seeds who need a shallow, no-drainage tray to hold consistent surface moisture during germination, before seedlings are transplanted into deeper cells or containers.

Frequently Asked Questions

Why does this tray skip drainage holes?

Seed germination generally benefits from consistent surface moisture rather than water draining away quickly, which is why this tray holds water at the tray level instead of letting it pass through. This is the opposite priority from a transplant tray, where standing water around roots is a problem.

Why is the profile so shallow at 1.29 inches?

A low profile matches the shallow depth most germination setups need, since seeds are germinating at or near the surface rather than developing an extensive root system yet. Seedlings are typically moved to a deeper cell tray once they germinate.

How much liquid does this tray hold?

This tray holds 241.59 cubic inches, or about 133.12 fluid ounces, across its standard 1020 footprint. That capacity is sized to support a full germination cycle before needing to be refreshed.

How long has T.O. Plastics made this type of tray?

T.O. Plastics has manufactured thermoformed horticultural trays since 1948, and this germination tray reflects that long-running focus on tray designs matched to specific stages of plant production.
