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

Star-Cell Plug Tray for Deep-Rooted Propagation, 38-Cell

A round or square cell can constrict root growth into a tight cylinder or box shape, which some propagation crops handle better than others. T.O. Plastics' Star Plug Tray uses a staggered, star-shaped cell cross-section instead, giving roots more surface area to spread into at the same overall cell depth.

This 38-cell tray uses a staggered 3x8/2x7 layout with cells measuring 2.13in OD by 4in deep (10.37 cu in), sized 10.94in W x 21.44in L with drainage holes, and ships 50 per case.

Key Features & Benefits

• Star-shaped cell cross-section — gives roots more surface area to spread into compared to a plain round or square cell.
• Staggered 3x8/2x7 cell layout — packs 38 deep cells into the tray footprint.
• 4in cell depth — supports crops that need more vertical root room during propagation.
• Drainage holes — keep irrigation water moving through the staggered layout instead of collecting at the base.

Who Should Use This Tray

This fits propagation growers whose crops benefit from extra root surface area and depth, choosing the star cell shape over a standard round or square plug for that stage of production.

About T.O. Plastics

Founded in 1948, T.O. Plastics builds its horticultural trays and inserts at two Minnesota facilities under Otter Tail Corporation ownership. The company reclaims plastic resin on a large scale each year, applying that material across its tray and container lines.

Frequently Asked Questions

What is the benefit of a star-shaped cell over a round or square one?

A star-shaped cross-section gives roots more surface area to grow into at the same overall cell footprint compared to a plain round or square cell. This can help some propagation crops establish a more developed root system before transplant.

How deep are the cells on this tray?

Each cell is 4 inches deep with a 2.13in outer diameter, giving 10.37 cubic inches of volume per cell. That is deeper than most standard plug tray cells, matching crops that need more vertical root room.

Does this tray have drainage?

Yes, this tray includes drainage holes so excess irrigation water passes through instead of collecting around the roots. It ships in a 10.94in x 21.44in footprint with a staggered 3x8/2x7 layout.

How many trays come in a case?

This tray ships 50 per case. Order enough cases to match your propagation run's cell count.
