TO Plastics 1020 Plant Trays 100-Pack — No Holes, Heavy-Duty Thermoformed Flats for Seed Starting & Hydroponics

TO Plastics 1020 plant trays (100-pack) are heavy-duty, thermoformed flats without drainage holes designed for seed starting, microgreens, hydroponics, and drip-tray use.

These traditional 1020-size trays deliver a robust, reusable platform when you need consistent containment rather than per-pot drainage. Thermoformed for reliable stacking and two-finger denesting, the design omits center bars and side ribs so pots and cells sit flat and evenly. Choose the no-hole option when you want to control moisture with bottom watering, trays for transport, or sealed beds for hydroponic setups.

Why choose a no-hole 1020 tray for seed starting?

No-hole trays keep moisture and nutrients inside the tray, reducing mess and enabling uniform bottom-watering or capillary mats. They suit tiny seeds and delicate mixes because the substrate stays consistently damp without rapid drainage. The heavy-duty construction supports frequent handling and reuse across seasons.

• Dimensions: 11" W x 21.37" L x 2.44" D for standard 1020 compatibility
• No drainage holes to maintain moisture and prevent spills
• Thermoformed strength for repeated use and transport
• Flat interior—no center bar or side ribs—so pots sit evenly

How does this tray perform in hydroponic or microgreen systems?

The sealed base is ideal for hydroponics and microgreens where you control water contact from below or use nutrient reservoirs. Because there are no bottom openings, you can set trays directly on ebb-and-flow tables, capillary mats, or flooded benches without loss of solution. The sturdy walls and low profile make harvesting and moving full trays easier.

• Compatible with bottom-watering and hydroponic reservoirs
• Low 2.44" depth keeps roots accessible and aerated
• Reusable design reduces replacement frequency and waste
• Works well with microgreen harvesting and commercial propagation

What handling and storage features should growers expect?

These flats include two-finger denesting for quick separation during setup or planting lines. The thermoformed profile nests tightly for compact storage and transport but lifts easily when you need individual trays. Without center bars or ribs there are fewer places for soil to collect, simplifying cleaning between crops.

• Two-finger denesting for faster preparation and staging
• Nests efficiently to save storage space when empty
• Smooth interior surfaces for easier cleaning and sanitation
• Heavy-duty walls stand up to handling and stacking with plants

Will these trays fit my existing pots and benches?

The 1020 footprint (about 11" x 21.37") matches industry-standard flats and trays, so most pots, cell packs, and bench layouts are compatible. The shallow 2.44" depth fits common shelving and bench heights while holding enough medium for seedlings and microgreens. Because the tray has a flat interior without obstructions, a wide variety of inserts and liners can be used.

• Standard 1020 size for broad compatibility with pots and inserts
• Flat interior accepts diverse pot shapes and cell trays
• Shallow depth fits typical greenhouse benches and racks
• Works with trays, liners, and mat systems used in propagation

Who is this for: growers, nurseries, urban farms, and hobby gardeners who require a durable, reusable flat for propagation, microgreens, or hydroponic setups will value the TO Plastics 1020 no-hole tray. It’s aimed at operations that need standardized sizing, easy handling, and moisture control—whether staging seedlings for sale, running continuous microgreen harvests, or organizing a propagation line.
