Starting Seeds Just Got a Lot Easier

Our Universal Bottom Tray (UBT) allows you to get the benefits of bottom watering without any mess.

No more dirty shelves or wet floors. The tray will keep all the water and soil with the plants, not all over your house. Each tray has an entirely flat bottom making it easy to clean.

There are no drainage holes, and the tray is 100% leakproof.

One Universal Bottom Tray can hold twelve Epic 6-Cell Trays OR eight Epic 4-Cell Trays.

Designed To Last

The engineered plastic construction is designed to have a high strength-to-weight ratio. The rugged construction will withstand all the abuse you can throw at it over the season and give you many years of productive use. A single tray can hold over 25 pounds without warping.

The trays are rigid and stiff, eliminating flexing that results in spills. The design makes them easy to lift and move around.

Our heavy-duty UBT is injection molded from UV-treated, BPA-free food-grade plastic (#5 – polypropylene).

The trays nest into each other reducing stacking height and saving storage space.

Versatile Across Many Seed Starting Methods

The Universal Bottom Tray is 100% compatible with air-prune, Winstrip-style trays, and any other 1020-size cell tray. They are perfect for 72 and 128-cell trays.

Need to start individual pots? No problem. Our UBT can hold eight 1-gallon pots or eighteen 3-inch pots.

With 200 square inches of space, these trays are incredibly versatile and will quickly become the most used tray in your nursery.

The UBT is also an industry-standard 10x20 size so that it will fit nicely on typical nursery shelves like wire racks.
