Awesome transaction and quick delivery

Fit ok

I bought these and a more expensive style/ brand. These don't fit the heavy duty trays quite as well as the other ones but I'm still happy with my purchase!

Janice Wheeler (Seattle, US)

Looking forward to putting my domes to work next week when I start my seeds.

flimsy don't see them lasting. There is no handle on top. You have to force the vents in place. Some came in place and some didn't.

Exactly what I wanted

I really like this dome lid for starting my plants from seed. The one that came with the tray I bought locally was too low and didn't have vents. This dome is high enough to let my plants grow enough for planting. The vents are helpful to keep the plants from burning or rotting.

7 inch covers are great

I bought 4 of the 7 inch covers just to see what they would do. The little hole covers --are worthless. BUT I love the covers. I can sprout seeds in a starter and then put them in a 10x20 tray with the cover on. It keeps them more moist and some warmer. They thrive and strengthen before being transplanted into the garden or pots. I intend to buy more.

Love These 7" Domes

Before I purchased these domes, I read all the reviews and was a little concerned. These were some complaints about how they were a bit flimsy and the vent covers weren't permanently attached, etc. However I really wanted a taller dome for my 5" deep plug trays so that I could grow hearty plants before transferring them into my gardens (and to protect them from my cat while indoors...). One of the complaints was that the plastic walls were too thin and that binder clips the purchaser used to secure the lids to the trays caused them to tear. Armed with this knowledge, I decided to make "seat belts" for my growing systems. They work fabulously! You can buy strap material and fastener clips from your local or big box hardware store. I have ten 50 plug tray & dome systems. The materials to make these "seat belts" cost $4.50 for each tray. Worth every penny and they look great. Also, I have no problem with the vent covers. On top of all that, my seeds are coming up more quickly than I expected so I'm a happy gardener!
