Who This Is For

You are switching to USA-made trays because your thin imports keep buckling when you lift them full of wet media.
You are adding a drainage system to your propagation setup because pooling water is causing root rot in your seedlings.

What We Found

We noticed these hold their shape when carried one-handed, unlike the thin imports that fold and spill your crop.
The drainage holes are spaced well enough that you can bottom-water without leaving dry spots in the corners.

What Users Say

Growers who switched from thin trays say they stopped losing clones to damping-off once the excess water could escape.
Users tell us the raised floor channels keep their root zones oxygenated even when the tray sits in a shallow runoff.

Grow1 USA Propagation Tray with Drain Holes (10" x 20")

Precision-engineered for professional growers, the Grow1 USA Propagation Tray with Drain Holes provides the ultimate drainage solution for clones and seedlings. Proudly manufactured in the USA, this premium tray is built with a thicker, heavy-duty plastic that offers superior structural integrity compared to the standard propagation tray with drain holes, ensuring it won't buckle or crack when fully loaded with wet media.

This version features integrated drainage holes across the base, making it the ideal choice for overhead watering systems or growers who prefer to let excess moisture escape freely. By preventing water from pooling at the base of your rock wool, seedling mix, or seedling plug trays, it protects sensitive young roots from "wet feet" and oxygen deprivation, significantly reducing the risk of root rot and damping-off.

The interior floor is designed with raised channels to elevate your 3.5 inch square pots or insert trays, allowing for maximum air circulation underneath. This increased airflow encourages air-pruning and ensures a well-oxygenated root zone. Durable, pliable, and crack-resistant, this USA-made tray is a foundational tool for high-success propagation cycles.

FAQ

When should I use a tray with drain holes? +

Trays with drain holes are best for "ebb and flow" systems or overhead watering. They allow excess water to escape immediately, ensuring roots don't sit in stagnant water, which is ideal for avoiding rot in humid environments.

How does the USA Premium version compare to standard trays? +

The USA Premium trays are manufactured with a higher density of plastic. They are much more resistant to cracking at the corners and won't flex as much when you lift them, providing better support for your plants.

Can I use this tray for bottom-watering? +

Because this tray has holes, it cannot hold water on its own. To bottom-water, you would need to place this tray inside a Grow1 USA Premium Propagation Tray with No Drain Holes to act as a reservoir.

What is the purpose of the raised channels on the bottom? +

The raised channels elevate your media or insert trays, allowing air to move freely beneath the drain holes. This prevents the holes from being blocked and improves overall root zone oxygenation.

Will standard 10x20 humidity domes fit this tray? +

Yes. Despite being a "Premium" build, it maintains standard industry dimensions. It is compatible with Grow1 domes as well as most other brands of seedling inserts.

Is the plastic BPA-free and safe for seedlings? +

Yes, the tray is made from high-quality, durable plastic that is safe for the propagation of all types of clones and seedlings, including food crops.
