128-Cell High-Depth PS Propagation Tray | Herbs & Flowers
The 128h high-depth PS propagation tray offers 4.8 cm (1.89 in) cells in an 8 × 16 arrangement — deeper than a standard 128-cell tray to support herbs, flowers, and leafy greens that require a longer nursery period. The extra depth lets root systems develop fully without becoming root-bound, while the high cell count maximizes bench space efficiency in commercial greenhouse operations.
High Density Meets Real Depth
Herbs and flowering ornamentals sit in a tricky spot. Growers want high cell density, but these crops also need depth. Most high-count trays stay shallow. Herbs and ornamentals then run out of root space and stall. The 128h solves the trade-off. It gives you 128 cells plus a deeper draw than most trays in this density class.
The 128h is our high-depth, high-density option. We built this 128 cell plug tray for growers who refuse to choose between count and root volume. It also shares the standard 1020 footprint, so it drops into existing benches and handling lines.
128 Square Cells, 8 x 16 Layout
Each tray holds 128 square cells in an 8 x 16 arrangement. The top opening measures 3.0 cm (1.18 inches) and tapers to a 1.5 cm (0.59 inch) base. Cell depth reaches 4.8 cm (1.89 inches). That depth supports herbs and ornamentals with longer seedling cycles, so roots grow down instead of stalling early. Square cells also pack the 1020 footprint without wasted gaps.
A single drainage hole in each cell keeps the deeper profile well drained. We thermoform the 128h from a single sheet of premium polystyrene. Even at the deeper draw, walls stay uniform and resist cracking. The result is a rigid tray that holds its shape through watering, stacking, and transplant. Among 128-cell formats, few trays match this depth.
Fits Your 1020 System on Day One
The 128h measures 54 x 28 cm (21.3 x 11.0 inches), the standard 1020 footprint. It nests inside 1020 watertight trays for bottom watering. It also sits flat on mesh benches and stacks neatly with other 1020 trays. You do not need to change benches, irrigation, or handling equipment.
Built for Automated Seeders
Drum seeders and needle seeders demand tight tolerances. We form the 128h with consistent cell pitch, opening size, and tray flatness. Every cell rim is clean and smooth, so needles and nozzles never snag. The rigid profile also resists flexing at high speed. That means fewer mis-picks, fewer jams, and more trays seeded per hour.
Light to Ship, Easy on Margins
Each 128 cell plug tray weighs just 155 grams. That low weight cuts freight cost directly. A pallet holds 3,520 trays, and a 40-foot high-cube container loads 77,440 units. For high-volume propagation, PS trays offer the lowest landed cost per cell. You get the deeper profile with no penalty on weight.
Best Crops for the 128h
- Herbs such as basil, parsley, and cilantro
- Flowering ornamentals with longer seedling cycles
- Leafy greens held past the usual transplant date
- Growers who want high density plus extra root depth
Material, Safety, and Reuse
We make every 128h from food-grade expanded polystyrene (PS #6). The trays are BPA-free with no intentionally added lead, cadmium, or heavy metals. Many municipal and commercial facilities recycle PS #6, so we recommend partnering with a local recycling program. These trays work best for single use or 1-3 careful cycles. If you need trays for repeated washing and multi-season use, take a look at our PP range instead.

What is the difference between PS and PP plug trays?
PS (polystyrene) trays are lightweight and precision thermoformed for the lowest landed cost — ideal for single use or 1–3 careful cycles. PP (polypropylene) trays are heavier, washable, and built for repeated multi-season use. Choose PS for cost and seeder compatibility; choose PP when you need trays that survive repeated washing across many seasons.
How many times can I reuse a PS tray?
PS trays work best for single use or 1–3 crop cycles with careful handling, gentle washing, and proper storage. Because PS is rigid, repeated flexing or aggressive washing can cause hairline cracks. For repeated washing and multi-season use, see our PP range.
Does this fit standard 1020 flats?
Yes. The 128h measures 54 × 28 cm (21.3 × 11.0 in), the standard 1020 footprint. It nests in 1020 watertight trays and works with standard 1020 benches and equipment.
Are these compatible with automated seeders?
Yes. The 128h is thermoformed to tight tolerances on cell pitch, opening size, and tray flatness, so it runs on common drum, needle, and vacuum seeders. Send us your seeder model and we will confirm fitment.
What crops work best in a 128-cell high-depth tray?
The 128-cell high-depth tray suits herbs (basil, cilantro, parsley), flowering ornamentals, and leafy greens on 4–6 week cycles. Its 4.8 cm (1.89 in) cells give roots more vertical room than a standard 128-cell tray.
