Yield Lab 7 Inch Propagation Dome - 5 Pack Humidity Vented Domes – Plant Growing Dome for Seedling, Germination, Soil & Hydroponic Horticulture

Strong trays, a good size to hold plant pots or smaller trays of seedlings.

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 for the price. High quality makes them reusable for years so long as you take care of them. They hold the humidity well and vents work as they should when needed.

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.

Sturdy enough. Good quality for the price.

The plastic clear dome is sturdy but the green discs do not stay in and one came broken. For the price it should have been way better

Worst Seedling trays I've ever bought. Sides break very easy. Even doubling them up doesn't really help. Buy something better...

Sturdy and great size
