Garden Supplies Tray Black 11 x 21, Known as 1020 Tray without Drainage

  The standard 1020 greenhouse flat without drainage slots.  Use with Jumbo Plug Flats and Pro-Tray Cell Flats to contain water drainage and for bottom-watering applications. All are standard size. 11" by 21". Trays and flats are made of 80% recycled scrap polystyrene and are reusable and recyclable. Compatibility: Use with Pro-Trays, Jumbo Plug Flats, Soil Block Propagation Trays,and Mini Square Plastic Pots.
They will hold 18 each 4 by 4 inch pots. They measure 21 inches by 11 inches by 2 inches deep.  Fill the bottom tray to water the seeds in the pots so you do not dislodge the seed by top watering. With our germination mix, the right amount of water will be absorbed for proper watering.  I use these in my greenhouse to start seeds.  They are reusable and sturdy. They last over several seasons before cracking.  They are a bit flimsy so we always use two of them together.
