The HC Companies Dillen 72-Cell Round Propagation Sheet - Black Thermoformed Propagation Tray - 6x12 Layout

Thermoformed Precision for Automated Round-Cell Propagation

Vacuum-formed trays can vary slightly cell to cell, which matters once a line is running automated de-nesting at speed. The HC Companies Dillen 72-Cell Round Propagation Sheet is thermoformed instead, a process that yields tighter cell-to-cell dimensional consistency across the 72 round cells arranged in a 6x12 layout on a 20.75in x 10.31in x 2.38in footprint.

Precision-punched drainage holes support optimal drainage and air pruning, and built-in stacking notches enable quick, reliable de-nesting on automated equipment, cutting handling labor on high-throughput seeding and propagation lines.

Key Features & Benefits

• 72-cell 6x12 round layout — maximizes cell count per tray footprint for high-density seed germination and cutting propagation.
• Thermoformed construction — delivers precise cell dimensions and wall consistency for automated seeding and transplant equipment.
• Precision-punched drainage holes — purpose-designed placement supports optimal drainage and air pruning from germination through transplant.
• Stacking notches — built-in notches enable quick, reliable de-nesting on automated equipment, cutting handling labor.
• Round cell shape — supports natural root ball development and can reduce root spiraling versus square-corner cells for some crops.

Who Should Use This

Commercial propagators, greenhouse growers, and nurseries running high-volume seed germination or vegetative cutting programs on automated transplant and seeding equipment are the direct fit for this sheet.

Frequently Asked Questions

How does thermoforming differ from vacuum-forming for propagation sheets?

Thermoforming uses heat and pressure to form the plastic, often yielding more precise cell geometry and wall consistency than vacuum-forming. That consistency matters for automated seeding and transplant equipment that depends on uniform sheet dimensions.

How many cells does the 72-Cell Round Propagation Sheet hold?

72 round cells in a 6x12 layout, with a total liquid volume of 3.49qt across tray dimensions of 20.75in x 10.31in x 2.38in. That capacity and footprint match the standard round-cell propagation format used elsewhere in the Dillen line.

Are the stacking notches compatible with all automated de-nesting equipment?

The stacking notches are designed for standard commercial automated de-nesting systems. Verify compatibility with your specific equipment model before placing a large-volume order.

Is the round cell format better for certain crops?

Round cells support natural root ball development and can reduce root spiraling for some crop types. Square cells may suit crops where root ball shape affects transplant fit, so match cell shape to your crop and downstream transplant requirements.
