Tray 11 x 21, Known as 1020 Tray without Drainage 1 Tray
Tray 11 x 21, Known as 1020 tray is the standard 1020 greenhouse tray 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 inches wide by 21 inches.
Trays 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 Pot.
They will hold 18 each 4 by 4 inch pots. They measure 21 inches long by 11 inches wide 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 a good 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. They last about 2 seasons before cracking.
We suggest using two of these trays when filling with 17 each 4 inch mini square pots. They are a bit flimsy when filled.
Special Note: With our new structuring, we will not have room for these so these are the last that we will be offering.
