T.O. Plastics Star Plug Tray - 38 Cell - 2.13in OD x 4in D - Black - 50pc

T.O. Plastics Star Plug Trays - Deep 4-Inch Cells for Superior Root Development

The T.O. Plastics Star Plug Tray delivers 38 cells in a staggered 3x8 and 2x7 arrangement across a 10.94in x 21.44in footprint. Each cell measures 2.13in at the top and reaches 4in deep, providing 10.37 cu in of growing volume - among the deepest cells available in the standard propagation tray format. The deep cell profile supports long, well-developed root systems before transplanting, reducing establishment time in the field or final container. An optional top support slotting system enables safe stacking of filled trays. Sold 50pc per case.

Key Features & Benefits

• 38 cells - staggered 3x8 / 2x7 layout - Staggered arrangement maximizes cell count across the tray footprint while providing adequate spacing for deep cell development.
• 2.13in OD x 4in deep - 10.37 cu in per cell - Deep 4-inch cells provide substantial root volume for crops that benefit from longer pre-transplant root development.
• Optional top support slotting system - Allows safe stacking of filled trays without compressing cells, protecting root systems during storage and transport.
• Drain holes in every cell - Prevents waterlogged media and supports healthy drainage throughout the deep cell profile.
• 10.94in W x 21.44in L footprint - Compatible with standard propagation bench and rack systems.
• 50pc per case - Case quantity for commercial production.

Who Should Use This

Greenhouse propagators and nursery growers producing transplants that benefit from deep pre-transplant root development - including trees, shrubs, perennials, and other deep-rooted crops. The 4-inch cell depth is especially valuable for reducing transplant shock in crops with naturally deep root systems.

Compatibility

The 10.94in x 21.44in footprint is compatible with standard propagation bench systems. Works with peat, bark, coco coir, and soilless growing media. Compatible with overhead and flood irrigation methods.

Frequently Asked Questions

Why choose a 4-inch deep cell over a standard-depth plug tray?

A 4-inch deep cell allows roots to develop a longer, more extensive root system before transplanting. This is especially beneficial for deep-rooted crops and transplants that must establish quickly in challenging field or container conditions.

What does the staggered cell layout mean?

The Star Plug Tray alternates between rows of 3 and 2 cells (3x8 and 2x7) in a staggered pattern. This offset arrangement allows deeper cells to fit efficiently within the tray footprint while maintaining structural integrity between cells.

How many trays come per case?

Each case contains 50 T.O. Plastics Star Plug Trays.

What is the top support slotting system?

The optional top support slotting system provides interlocking slots or ridges along the tray top that allow multiple filled trays to stack securely without crushing the cells of the tray below.
