T.O. Plastics Standard 1020 Deep Jumbo Insert #606 - 36 Cell - 4x9 - Black - 100pc

Deep-Cell 1020 Insert for Extended Root Development, Deep Jumbo Insert #606 36-Cell

Standard-depth insert cells work for most seedling starts, but crops that need more time in a cell before transplanting can outgrow that depth before they are ready to move up. T.O. Plastics' Deep Insert line adds extra cell depth on top of the same straight-wall, easy-de-nesting design as its standard 1020 inserts, giving roots more room to develop before transplant.

Each cell in this Deep Jumbo Insert #606 measures 2.00in x 2.25in x 3.25in D (12.53 cu in), arranged in a 36-cell, 4x9 layout that fills a standard 1020 flat tray footprint despite the added depth.

Key Features & Benefits

• Extra cell depth — gives roots more room to develop than a standard-depth 1020 insert before transplant.
• Straight cell walls — maximizes usable soil volume per cell instead of narrowing toward the bottom.
• Clean de-nesting despite the added depth — keeps stack separation fast even with deeper cells than standard inserts.
• Molded in black, 100 pieces to a case — sized for restocking a commercial liner or seedling program in one order.

Who Should Use This Insert

This fits growers who need extra cell depth for crops that spend more time in a cell before transplanting, such as larger seedling starts or liners, rather than a standard-depth 1020 insert.

Frequently Asked Questions

How much deeper is this insert than a standard 1020 insert?

T.O. Plastics' Deep Insert line adds meaningful cell depth over its standard 1020 Insert line, giving roots more vertical room before the plant needs to size up. Exact depth varies by model, so compare the specific cell dimensions of the deep and standard versions you are considering.

Does this insert fit a standard 1020 flat tray?

Yes, this insert fits a standard 1020 flat tray footprint despite the added cell depth. Confirm your flat tray has enough clearance for the deeper cells if it is being used in a shelving or benching system with limited vertical spacing.

Why choose a deep insert instead of just transplanting sooner?

A deep insert lets a crop stay in the same cell longer without becoming root-bound, which can reduce transplant shock and the number of handling steps compared to moving plants to a larger container sooner. This matters most for crops grown to a larger starting size before their final transplant.

What is the cell volume on the Deep Jumbo Insert #606?

Each cell on the Deep Jumbo Insert #606 measures 2.00in x 2.25in x 3.25in D, giving 12.53 cubic inches of soil volume in a 36-cell, 4x9 layout. That is more volume than most standard-depth 1020 inserts provide, matching the extra root room this line is built for.
