Seed Tray Propagator Kit 120 Cells, 40 Cells per Tray Clear Lids, Plant Germination, Windowsill Greenhouse Starter Plastic Grow Trays (3 Seed Trays)

Great product have used them already

Each tray has 40 cells and I've filled all three of them. The seeds have had no trouble growing even when stacked on top of each other on my windowsill. They are fun to transplant as they generally can just be pulled from the stalks to get out the entire cell as a cube of soil. You get a couple that the roots grow through the hole in the bottom of the top plastic layer but they can be pushed out from the bottom of the tray. The tray is still strong enough to be reused after this so I can see myself getting a least a couple of years use of these propagators.

The trays themselves are not very strong. They rip/split when you try to get the stack apart.

just right to get plug plants started. fit nicely to my windowcill.

Excellent product. Does the job!
