Speedling Drain Tray

No, this tray is specifically designed for indoor use. It is best suited for controlled environments like greenhouses, grow rooms, or indoor shelving where you need to manage water runoff.

Because the tray is watertight, you can fill it with a shallow layer of water and place your seedling cells directly inside. The plants will absorb the moisture through the drainage holes in their cells, which encourages stronger root growth and prevents the foliage from getting wet.

The tray measures 31 inches by 16 inches, so it is designed to accommodate specific compatible seedling transplant trays. We recommend measuring your existing flats to ensure they fit within these dimensions before purchasing.

No, the tray itself is designed to be a solid basin to catch excess water and prevent leaks on your indoor surfaces. If you need drainage for the plants themselves, that should be handled by the seedling cells or inserts you place inside the tray.

The rectangular shape and consistent dimensions allow you to line up multiple trays side-by-side on standard shelving units. This creates a uniform, expandable growing surface that makes it easy to organize large batches of seedlings.
