Who This Is For

You are adding drainage to your setup because stagnant water at the tray base kills young root systems.
You are switching to trays with raised channels because you need air to move under your pots to prevent rot.
You are moving away from single-use trays because they warp and crack under the weight of wet media.

What We Found

We found the pliable plastic handles drops better than rigid trays that snap under pressure.
The channels lift inserts just enough to let air move without making the whole setup feel unstable.

What Users Say

Users who switched to these say they stopped losing cuttings to root rot during the first week of rooting.
People running 72-cell inserts report these trays fit perfectly without the edges catching on the walls.

Grow1 Standard Propagation Tray With Drain Holes (10" x 20")

Overwatering is one of the most common causes of failed clones and seedlings — and a tray that can't drain works against you from the start. The Grow1 Standard Propagation Tray | With Drain Holes allows excess water to drain freely from the base of your cuttings and seeds, preventing root saturation and keeping your propagation media at the right moisture level throughout the rooting phase.

Raised base channels lift insert trays and 3.5 inch square injection molded pots off the tray floor, promoting air circulation beneath the root zone and reducing the risk of anaerobic conditions even when water pools below. Built from pliable, crack-resistant plastic, the tray withstands repeated use across propagation cycles without warping or splitting under the weight of wet media and inserts.

Manufactured in the USA to consistent dimensional tolerances, the Grow1 Standard Propagation Tray | With Drain Holes is a reliable foundation for any propagation setup — from small hobby benches to commercial clone rooms. This model is perfectly sized to support a 72-cell deep seedling plug tray and other standard inserts.

FAQ

What's the difference between a tray with drain holes and one without? +

Trays with drain holes allow excess water to drain freely from the base of cuttings and seeds, preventing root saturation — ideal for setups where overwatering is a concern. Trays without drain holes catch and retain moisture beneath the media, better suited for rock wool and starter plugs that benefit from consistent bottom-up hydration.

What media can I use with this tray? +

This tray works well with rock wool cubes, seedling mix, starter plugs, and any propagation media that benefits from free drainage. The drain holes prevent water from pooling beneath your media, keeping moisture levels in check throughout the rooting phase.

What do the raised channels on the base do? +

The raised channels lift insert trays and pots slightly off the tray floor, allowing air to circulate underneath even when the tray is sitting on a flat surface. This promotes healthier oxygen levels at the base of your propagation media and prevents roots from sitting in standing water.

Can this tray be reused across multiple propagation cycles? +

Yes — the tray's pliable, crack-resistant plastic is built for repeated use. Between cycles, clean with a diluted hydrogen peroxide or bleach solution to eliminate pathogen buildup before reloading with fresh media and cuttings.

Does this tray work with propagation domes? +

Yes — the Grow1 Standard Propagation Tray | With Drain Holes is compatible with multiple Grow1 propagation domes. Check Grow1's dome lineup to find the right fit for your setup and humidity requirements.
