MIXC Humidity Dome 7" Tall 1020 Flat Trays Cover, 10 Pack, Propagation Seed Cloning Kit Super Sprouter Lid Vented for 10 x 20 Inch Flat Tray and Seed Starting Germination

These are pretty solid lids, and the extra height is very nice, they fit properly and the handle on the top is a nice addition. Mine was missing 3 of the green disks when I got it, not a huge deal because I have quite a few of these, I can scrap them up, but less 1 star due to packaging and loss of pieces

We just received these, so do not have multiple seasons of use to do a long term evaluation. These arrived without any damage, which is always an issue with this type of product. We use these for germinating seeds and then growing seedlings. The 1020 trays and domes are placed on heat mats. After 2 to 3 months, they go into storage for the next season. In the past, we have gotten at least 10 years out of a plastic dome as they are under fluorescent and/or LED lights rather than in very much sunlight. The vents on these are very nice, but you need to be careful when installing them by taking care to support the inside of the dome and then snap them into place. Like all of these things, they have gotten more expensive over the years, but these are competitive, particularly considering there are 2 top and 2 side vents. The plastic appears durable, only time will tell if they get brittle and crack easily.

They were missing 7 of the green vent covers, otherwise we like this item

Arrived missing 1/2 the green humidity dials. Product not very useful without them. No option to have just the humidity dials replaced and have to return whole product to fix issue. Plastic is also more flimsy then other tall humidity domes I've ordered in the past.

They are a bit pricey for being thin plastic and they don't really fit the cell trays. Mine was also missing 4 of the vents and there's no option to get customer support or replacements without just returning all of the domes entirely.
