Who This Is For

  • You are switching to round cells because square inserts feel too tight when you try to pull delicate root plugs out.
  • You are moving to heavy-duty trays because the flimsy imported versions snap every time you try to pop out a seedling.

What We Found

  • The extra depth in these cells gives your crop a head start that standard shallow trays just cannot match.
  • We like the round cell design because it leaves enough room to grab the starter plug without smashing the media.
  • The plastic is pliable enough to pop out a plant with one thumb, even when the root ball is tightly packed.

What Users Say

  • High volume nurseries say the recessed plug depth protects the media during fast handling and stacked transport.
  • Users who switched from square cells report that the round shape provides much more even moisture distribution.
  • Operators say these trays lasted through multiple seasons of heavy use without showing any signs of stress fractures.

Grow1 USA 50 Cell Round Propagation Tray (10" x 20")

The Grow1 USA 50 Cell Round Propagation Tray is the industry standard for growers seeking a balance of durability and operational efficiency. Proudly manufactured in the USA, these Grow1 trays are constructed from a premium pliable plastic that is significantly more robust than standard seedling inserts. Engineered to resist cracking and warping, they provide a reliable, reusable foundation for your most critical propagation cycles.

Each of the 50 round cells features a depth of 2.38 inches, offering substantial vertical space for root establishment. This extra volume is ideal for starting robust indoor crops like peppers and tomatoes, ensuring seedlings have the root mass necessary to thrive once transplanted. The round cell design is particularly advantageous for air circulation and uniform moisture distribution across the media.

This tray is the perfect companion for Cultiwool Round Macro Plugs (CUL005). While square cell seedling trays can be overly tight, these round cells provide a snug fit with just enough "wiggle room" for rapid placement and stress-free removal. Plugs sit approximately 1/8" below the tray surface, protecting the media and making handling exceptionally efficient for high-volume nurseries.

FAQ

Why choose round cells over square cells?+

Round cells are specifically designed to accommodate round starter plugs (like rock wool or peat) with a perfect balance of friction and clearance. This makes placement and extraction much faster than trying to force round media into square corners.

Which rock wool plugs fit this tray best?+

This tray (SKU 312005) is specifically designed for Cultiwool Round Macro Plugs (CUL005). They provide a snug fit with a small amount of wiggle room for the easiest possible handling during high-volume propagation.

Is this tray deep enough for heavy-feeding vegetables?+

Yes. The 2.38" depth is excellent for peppers, tomatoes, and other seedlings that require more vertical root space than standard shallow nursery flats provide.

Will this fit inside a standard 10x20 propagation tray?+

Absolutely. It follows the standard 10" x 20" industry footprint, allowing it to drop into no-drain propagation flats and fit under standard humidity domes.

How many times can I reuse this tray?+

Because it is made in the USA with higher-quality, pliable plastic, these trays are built for multiple seasons of use. Unlike brittle trays that crack after one transplant, these are designed for durability.

How do I sanitize this for my next crop?+

We recommend cleaning with warm water and a mild detergent, followed by a soak in a diluted hydrogen peroxide or bleach solution to ensure no pathogens are carried over to your next batch of seedlings.
