The HC Companies Dillen 1801 Deep Traditional Insert - 18-Cell Black Nursery Insert - 21in x 10.5in x 3in

Dillen 1801 Deep Traditional Insert - 18-Cell Standard-Footprint Deep Nursery Container

The HC Companies Dillen 1801 Deep Traditional Insert combines the standard 21in x 10.5in flat footprint with an extra-deep 3in cell profile, delivering more root volume per cell than a standard-depth 1801 insert. Vacuum-formed from durable black plastic with precision-burned drainage holes and die-cut trims, this insert suits crops that benefit from deeper root development during the germination and propagation stages - without requiring a change in flat or bench configuration.

Key Features & Benefits

• Standard 1020 Footprint with Deep Profile: 21in L x 10.5in W fits standard flats and benching systems while the 3in depth provides significantly more root zone volume than standard 2.25in inserts.
• 18-Cell Layout: 18 individual cells in a standard arrangement for efficient bench utilization and accurate stand counts in bedding plant and perennial production.
• Vacuum-Formed Construction: Consistent wall thickness and cell geometry deliver predictable root development and uniform transplant performance across every batch.
• Precision-Burned Drainage Holes: Reliable drainage and air pruning prevent waterlogging and support healthy root structure even with the added cell depth.
• 13oz Total Liquid Volume: The deeper cell holds more growing medium and moisture, reducing watering frequency for crops with higher early-stage water demand.
• Die-Cut Trims: Clean edges and accurate cell separation support smooth handling on manual and automated transplant lines.

Who Should Use This

Growers producing perennials, larger annuals, or any crop that benefits from a deeper root zone during propagation will find the 1801 Deep a useful step up from standard-depth inserts. It uses existing standard 1020 flat inventory, so no new flat investment is required.

Compatibility

The 1801 Deep Traditional Insert is compatible with standard 1020 flats including models TND10200, TWA10207, and TWA10200. Confirm flat depth clearance before using with dome or cover systems, as the 3in profile is taller than standard-depth inserts.

Frequently Asked Questions

How does the 1801 Deep differ from the D1801 Standard Insert?

The 1801 Deep measures 21in x 10.5in x 3in versus the D1801 Standard at 21in x 10.5in x 2.25in. The deeper profile provides more root volume but uses the same standard 1020 flat footprint.

How many cells does the 1801 Deep hold?

18 cells with a total liquid volume of 13oz across the standard 1020 footprint.

Will the 1801 Deep fit under standard dome covers?

The 3in cell depth is taller than standard-depth inserts. Measure dome or cover clearance before combining with existing propagation dome systems.

What flats are compatible with the 1801 Deep?

Standard 1020 flats including TND10200, TWA10207, and TWA10200. Always verify flat interior dimensions for proper fit.
