What the Quad Thick 1020 Tray Does That a Standard Flat Cannot
Most 10 x 20 trays are vacuum formed, which is why they crack at the corners after a season. This one is injection moulded at roughly four times the wall thickness, measuring 10 x 20 x 2.25 in deep. The base carries raised channels, so pots and inserts sit slightly proud and air moves underneath instead of water pooling against the plastic. No drain holes means it holds runoff rather than passing it to the bench. That is what you want under a plug insert, and not what you want under finished pots. Carry one full of water and the difference in flex is immediate. The cost per tray is higher, and that only pays back if the trays stay in service for several seasons.
Where a Heavy Duty 1020 Tray Earns the Extra Cost
A heavy duty 1020 tray makes sense anywhere trays get moved while loaded, which in practice means propagation benches and anything on wheels. Thin flats twist when lifted from one end, and a twisted flat spills. These do not, and they stack without nesting so tightly that they jam. Fodder growers use the same tray because it takes repeated soaking and rinsing without going brittle. Wash them between crops with a mild sanitiser and they come up clean, since the moulded surface has no vacuum-formed seams to trap residue. The trade is weight and storage volume, because a stack of these takes more shelf than a stack of thin flats.
Key Features
- Four times standard thickness: Injection moulded rather than vacuum formed, which is where thin trays crack first.
- 10 x 20 x 2.25 in: A true standard footprint with useful depth for holding runoff.
- No drain holes: Keeps water in the tray rather than on the bench, which suits plug inserts.
- Raised base channels: Pots and inserts sit proud, so air moves under them instead of water pooling.
- Rigid when loaded: Lifts from one end without twisting, which is what makes a full tray spill.
