10x20 Inch Black Plastic 10 Pack Plant Propagation Tray – Growing Trays for Garden, Planting, Seedling, Soil & Hydroponic Horticulture - Microgreen Trays Grow Plants - No Drain Holes

Great quality great price fast shipping and highly recommend

A first they seemed a little flimsy, but these trays hold 15 of some larger 4" square pots that I was having trouble fitting into a different style of 1020 trays. So I will purchase more for the 4" square pots.

Great domes for trays, superior quality and strength.

The plastic is definitely heavier than the store covers that come with the little kits, so this will hold up much better. The vent holes are a nice touch and can be opened and closed at will. Fits perfectly on a 10x20 tray. But, as in the specs, these are tall. I thought the height was a good thing, and maybe for certain plants it is, but once seedlings have broken through the surface, continued use of covers will lead to mold on the soil, and I sure don't need plants 7 inches tall inside a humid dome being attacked by fungus. My mistake. Maybe some plants need a 7-inch dome and for those this would work well, but mine sure don't.

Bunch of trays. I use them for everything. They are not hard plastic but they work well enough. Fit the 1020 domes fine

Should be thicker they are not animal proof and crack or break often.

Thin and flimsy plastic, but good size. A few came torn and bent. They're fine if you're using them as catch trays or growing microgreens. But you definitely can't carry these things if it's loaded with plants. Going to keep them anyway because it's a hassle to return and they'll still be useful if used right. Would not buy again though.

Just what I needed to clone some taller starts. They are working great with my black trays.
