Landmark Plastic Round 1020 Plug Sheet - 72 Cells - 6x12 - 2.54in Cell - Black

72PS Round Plug Sheet with Air-Pruning Base for Superior Propagation

The Landmark Plastic Round 1020 Plug Sheet -- 72PS provides 72 round cells in a 6x12 layout across a standard 10.42in x 20.85in footprint. Each 2.54in cell on the 72PS features a burned drainage hole and circle ridge bottom for improved water management and root guidance. The 72PS is thermoformed for consistent cell geometry and durability through repeated production cycles.

Key Features & Benefits

• 72 Cells -- 6x12 Layout: Round cell configuration across a standard 1020 footprint for compatibility with commercial propagation systems.
• 2.54in Cell Diameter: Precision round cells for uniform plug formation and consistent transplant sizing on the 72PS.
• Burned Drainage Hole: Heat-formed sealed hole at the base of each 72PS cell allows drainage while maintaining plug integrity.
• Circle Ridge Bottom: Molded ridges at the 72PS cell base air-prune roots, encourage lateral branching, and prevent root circling.
• Tray Dimensions: 10.42in W x 20.85in L x 2.38in D: Standard 1020 footprint keeps the 72PS compatible with propagation benches and rack systems.
• Thermoformed Construction: Consistent cell walls and stable structure keep the 72PS reliable across automated and manual propagation workflows.

Who Should Use This

Professional propagators and commercial nurseries running the 72PS want consistent round plug geometry and reliable drainage in a standard 1020 tray format. The 72PS suits growers who prioritize cell count per tray over the lower cell count of the 50PS.

Compatibility

The 72PS fits standard 1020 (10.42in x 20.85in) propagation tray carriers and bench systems, and works with peat plugs, coco coir, and soilless mixes sized for the 72PS's 2.54in cells.

Frequently Asked Questions

What is a burned hole on the 72PS, and how does it differ from a punched hole?

On the 72PS, a burned hole is formed by heat, producing a smooth sealed edge that retains plug structure while allowing drainage, unlike punched holes which can create rough edges or stress fractures in the cell wall. The 72PS's tighter 6x12 layout keeps that seal consistent across a higher cell count per tray than the 50PS.

What does the circle ridge bottom do on the 72PS?

The circle ridge bottom on the 72PS air-prunes roots as they reach the base, stimulating lateral branching and preventing root circling for a healthier, more fibrous root system. The 72PS's ridge sits at a deeper 2.54in cell than the 50PS.

How many cells does the 72PS plug sheet have?

The 72PS has 72 cells in a 6x12 arrangement, each measuring 2.54in in diameter. That 6x12 layout is sized for maximum cell count per tray, trading some per-cell volume for higher throughput than the 50PS.

What tray carrier fits the 72PS plug sheet?

The 72PS plug sheets fit standard 1020 tray carriers measuring 10.42in W x 20.85in L, compatible with most commercial propagation bench and rack systems. Confirm your carrier depth clears the 72PS's 2.38in tray height before ordering in volume.
