Lightweight Shallow Trays – 36 Count

20-Row Seed Flats and Plug Flats fit perfectly in these sturdy trays, allowing them to be well supported and bottom-watered. At our research farm, we use them as covers for bench top germination because they don’t heat up as much as clear domes. Outside dimensions: 10.8 x 21.25″; 1.3″ deep. White. Compatibility: Use with 20-row Seed Flats, Soil Block Propagation Trays, and Plug Flats. Not compatible with Jumbo Plug Flats or Pro-Trays.
