Who This Is For

  • You are moving to deeper trays because shallow nursery flats cause your young plants to become root-bound too quickly.
  • You are choosing pliable plastic because brittle trays crack after one season and make transplanting a struggle.
  • You are maximizing your nursery footprint because you need to start 72 plants without sacrificing root room.

What We Found

  • These feel different in your hands because the plastic is pliable rather than rigid, so it survives more cycles.
  • The 2.5 inch depth is the sweet spot for vigorous crops that need a solid head start before moving to larger pots.
  • We like that these seat perfectly into standard 1020 flats without the edges popping up or leaving gaps for air.

What Users Say

  • Growers who switched from nursery flats say they stopped buying replacements every season because these do not crack.
  • Users who check root mass before transplanting report much longer taproots compared to standard shallow cell trays.

Grow1 72-Cell Seedling Tray - 10" x 20"

The Grow1 72 Cell Seedling Tray is the industry standard for high-efficiency propagation, allowing you to start dozens of plants in a single 10" x 20" footprint. Proudly made in the USA, these trays are manufactured from a high-quality, pliable plastic blend that far exceeds the durability of standard, brittle nursery flats. For growers who prefer circular cells, we also carry the 72-cell round seedling tray featuring the same professional-grade construction.

Unlike shallow inserts that can lead to root-bound seedlings, each of the 72 cells features a 2.5-inch depth. This added vertical space is critical for developing a robust root architecture, particularly for vigorous vegetable starts like peppers, tomatoes, and herbs. If you often find yourself needing to separate specific sections of your nursery for transplanting, consider using the 72-cell break-a-part seedling tray for easier handling.

Each cell is equipped with precision-cut drainage holes to ensure a healthy air-to-water ratio and prevent waterlogging. These trays are perfectly compatible with USA-made propagation trays and humidity domes, making them a seamless addition to any indoor nursery, greenhouse, or grow tent setup. If you need a high-density starting solution that doesn't compromise on root health, the Grow1 72-cell tray is the professional choice.

FAQ

How many seeds should I put in each cell?+

For most vegetables like tomatoes or peppers, 1-2 seeds per cell is recommended. Once they sprout, you can thin them to one plant per cell to ensure each seedling has the full 2.5" of depth to grow its root system.

Are these trays reusable?+

Yes. Because these are made with a pliable, crack-resistant plastic blend, they are designed to last much longer than standard "single-use" nursery flats. Simply wash and sanitize them between uses.

Will this fit inside a standard 1020 tray?+

Yes, this 72-cell seedling tray is designed to drop perfectly into a standard 1020 propagation tray (with or without holes), making it easy to carry and bottom-water your plants.

What is the benefit of the 2.5" depth?+

The 2.5" depth allows for a deeper soil volume, which holds more moisture and nutrients. More importantly, it gives the plant more vertical room for taproot development, which prevents the plant from becoming root-bound as quickly as it would in a shallow tray.

Can I use a humidity dome with this tray?+

Yes, since it maintains the standard 1020 footprint, it is compatible with all standard propagation domes, including the popular 2" and 7" heights.
