Landmark Plastic T Series T1203 True Insert Pack - 36 Cells - (12) 3-Packs - Black

T Series True Insert Pack -- Deep-Cell Precision for Standard 10x20 Propagation

The Landmark Plastic T Series T1203 delivers 36 cells in (12) 3-packs across a 10.00in x 20.00in footprint. Each cell measures 1.53in W x 3.03in L (5.18 fl oz / 9.35 cu in), sized for efficient, high-density seedling and cutting production. Molded from durable black polystyrene to the same precision tolerances Landmark's T Series is known for across professional propagation operations.

Key Features & Benefits

• 36 Cells -- (12) 3-Packs: Higher cell count per tray for efficient propagation and easy transplanting with consistent cell spacing.
• Cell Size: 1.53in W x 3.03in L: 5.18 fl oz (9.35 cu in) per cell, sized for standard-turnaround seedling and cutting production.
• Tray Footprint: 10.00in x 20.00in x 2.61in: Standard T Series footprint compatible with 10x20 propagation tray systems.
• Black Polystyrene Construction: Smooth inner cell walls support clean plant extraction with minimal root disturbance at transplant.
• Precision-Molded Tolerances: Consistent cell geometry supports reliable de-nesting on manual and automated transplanting lines.

Who Should Use This

The T1203 is the everyday workhorse pick for commercial propagators and nursery operations running high volumes of standard-size seedlings and cuttings, where a reliable, widely-compatible 10x20 insert matters more than maximum per-cell root volume.

Compatibility

Designed to work with T Series tray carriers and 10.00in x 20.00in propagation bench systems. Compatible with peat, coco coir, and soilless growing media. Works with flood, overhead, and capillary mat irrigation methods.

Frequently Asked Questions

What is the cell volume of the T1203 insert?

Each cell holds 5.18 fl oz (9.35 cu in) with dimensions of 1.53in W x 3.03in L. That's a smaller per-cell volume than the Super Jumbo T1202SJ, trading root volume for a higher cell count per tray.

What distinguishes the T Series from Landmark's L Series line?

The T Series True Insert features a 10.00in x 20.00in footprint and deeper cell profile, offering greater growing volume per cell compared to Landmark's separate L Series 10.42in x 20.85in insert packs. Growers typically pick between the two lines based on tray-carrier compatibility and desired cell volume.

Is the T1203 insert automation compatible?

Yes -- T Series inserts are manufactured to precise tolerances for consistent de-nesting and compatibility with commercial propagation line equipment. That consistency reduces jams and misfeeds on automated transplanting lines.

When should I choose the T1203 over the Super Jumbo T1202SJ?

Choose the T1203 when you're running standard-turnaround propagation and want the highest cell count per 10x20 tray. Choose the Super Jumbo T1202SJ instead when your cuttings need extra root volume before transplant.
