T.O. Plastics Square Plug Tray - 392 Cell - 14x28 - 0.70in x 1.15in D - Black - 50pc

T.O. Plastics Square Plug Trays with Stacking Support for Efficient Plug Production

The T.O. Plastics Square Plug Tray - 392 Cell provides 392 square cells in a 14x28 configuration across an 11in x 21.22in footprint. Each cell measures 0.70in at the top opening with a 1.15in depth, providing 0.37 cu in of growing volume per plug. An optional top support slotting system allows trays to stack securely without crushing the cells below - protecting media and root systems during storage and transport. Sold 50pc per case.

Key Features & Benefits

• 392 cells - 14x28 layout - Precise cell arrangement optimized for uniform plug production across the 11in x 21.22in tray footprint.
• Cell dimensions: 0.70in top x 1.15in D - 0.37 cu in per cell for consistent growing volume and uniform root development.
• Optional top support slotting system - Interlocking slot design allows safe stacking of filled trays without compressing the cells below.
• Square cell geometry - Maximizes soil volume per cell and keeps plugs square for consistent transplant sizing and spacing.
• 11in W x 21.22in L footprint - Slightly oversized versus standard 1020 for bench and rack compatibility with a full-coverage cell layout.
• 50pc per case - Case quantity suited for commercial plug and seedling production operations.

Who Should Use This

Commercial plug producers, greenhouse growers, and nursery propagators who need a reliable, high-quality square plug tray with stacking capability. The 392-cell format is well suited for high-density seedling production where bench space efficiency is the priority.

Compatibility

The 11in x 21.22in footprint fits standard propagation bench and rack systems. Compatible with peat, coco coir, and soilless plug mixes. Works with overhead, flood, and ebb-and-flow irrigation methods.

Frequently Asked Questions

What is the top support slotting system?

The optional top support slotting system consists of interlocking slots or ridges along the top edge of the tray that allow multiple filled trays to stack safely - the top of the lower tray supports the base of the upper tray without touching or compressing the cells below.

What is the soil volume per cell?

Each cell holds 0.37 cu in of growing media in a 0.70in square x 1.15in deep cell - providing a small but precise volume for high-density plug production.

How many trays come per case?

Each case contains 50 T.O. Plastics Square Plug Trays, packaged for commercial propagation facilities and greenhouse operations.

What trays and bench systems are compatible?

The 11in W x 21.22in L footprint fits standard commercial propagation bench and rack systems. While slightly larger than a standard 1020, this tray is designed for direct bench use rather than insertion into a carrier tray.
