The HC Companies Dillen 606 Standard Jumbo Insert - 36-Cell Black Insert - 20.5in x 10in x 3.25in

Extra Root Volume in a 36-Cell Deep-Profile Insert

A standard-depth cell can run out of root volume before a larger bedding plant is ready to transplant, slowing growth right when it should be accelerating. The HC Companies Dillen 606 Standard Jumbo Insert holds 36 cells in a 6x6 arrangement across a 20.5in L x 10in W x 3.25in H footprint, with the jumbo depth delivering substantially more root volume than standard 2.25in-depth inserts.

Vacuum-formed from durable black plastic with precision-burned drainage holes and die-cut trims, the 606 Standard Jumbo is compatible with a broad range of standard 1020 flats despite its deeper profile.

Key Features & Benefits

• Jumbo 3.25in depth — provides 1.33qt total liquid volume and significantly more root zone than standard-depth inserts.
• 36-cell 6x6 layout — standard grid accommodates 36 plants per insert for efficient bench utilization.
• Broad flat compatibility — 20.5in x 10in footprint fits a wide range of standard 1020 flats and bench systems.
• Vacuum-formed construction — consistent wall thickness and cell geometry deliver predictable root development batch to batch.
• Precision-burned drainage holes — reliable drainage and air pruning maintain healthy root structure at the deeper cell depth.

Who Should Use This

Greenhouse growers producing larger bedding plants, spring annuals, or any crop that benefits from additional root volume in propagation will find the 606 Standard Jumbo a practical step up from standard-depth 36-cell formats.

Frequently Asked Questions

How does the 606 Standard Jumbo differ from the D606 Standard Insert?

The 606 Standard Jumbo measures 20.5in x 10in x 3.25in with a deeper cell profile and 1.33qt total volume, while the D606 Standard Insert is shallower at 2.25in depth. Use the Jumbo for crops needing more root volume.

How many cells does the 606 Standard Jumbo hold?

36 cells in a 6x6 configuration, with a total liquid volume of 1.33qt and a cell depth of 3.25in. That combination is what sets the Jumbo apart from standard-depth 36-cell inserts.

Will the 606 Standard Jumbo fit under standard dome covers?

The 3.25in depth is taller than standard-depth inserts, so dome clearance is not guaranteed. Measure clearance before combining it with an existing propagation dome system.

What flats are compatible with the 606 Standard Jumbo?

TND10200, TWA10207, TWA10200, TVA11210, TVA11212, and TVA.R6.0. Verify flat interior dimensions before ordering to confirm proper fit.
