Propagation: Anyone use this type of greenhouse before?, 1 by Zarebeth

I have a bunch of these - some more sturdy than others, and I love them. However, I start my seeds in the basement, and use them to harden off my seedlings as soon as the weather gets a little better, and to hold them until frost danger passes. I keep them in a mostly shaded spot, with the doors open until evening. Then I zip them shut at night. I don't think they are the best for starting seeds, but I don't live in CA anymore so they may work perfectly fine for that. I wouldn't (and don't) trust them to keep my babies safe from really cold temps... they get moved into the garage at the first hint of frost.
