I found this short but informative article on Coldframes If you have followed my articles, you might note a few areas that need to be done a little differently.
If one wishes to overwinter a perennial, the perennial must stay dormant. Most perennials do require a little rest and some require vernalization (a cold treatment long enough for the plant to at least think it has gone through winter). Now the ones you have planted in the ground are not the perennials I am discussing here. These would be perhaps perennials you seeded last summer, and grew on through the fall. They are in the greenhouse in a bed or in a pot. So, the mention of a warm, sunny day in a cold frame bothers me. I do not want my plants to wake up and then freeze on a daily basis. Also, if the plants are not dormant, I have to water them. I have tackled this problem in several ways.
One is to leave the cold frame door open for the winter. That way it does not warm up too much. The bad thing is that if we get very cold weather, I am just scatterbrained enough to forget to close the door.LupinesRussell Mix
Another way, which is much preferred, is to cover the plants with microfoam (a thick foam blanket) or some type of mulch, like wood chips. You lay any tall plants on their sides back in the fall, after they have gone to sleep. Cover all of them, and most will survive quite well till Spring. Now you can leave that door ajar, and all will be fine.Rudbekia Goldstrum
But the newest most sensible thing I have learned about is opaque white plastic. You use this as the cold frame covering for the winter. Since it is opaque, no sun can get in. Since it is white, the heat will not collect either. No sun means the plants do not warm up enough to break ....[MORE]

Can't Afford New, Buy Used!
Someone somewhere will be selling a greenhouse they have outgrown or have become tired of. I think it is a good idea to browse around and see what is offered.
My first stop was to Green House Trade Industry On Line, where I clicked on Classified Ads, then Equipment http://www.greenhouse-bbs.com/clasequi.htm. There is alot of great stuff on this page. Scroll down, some is too big, but there are lots of good deals in here. The one big catch is, this page does not get updated as often as it should. You may write off to find the item has already been sold. Next I hopped to one of my favorite haunts at h2othouse. They have a section on used greenhouses for sale and a list of wanted to buy, http://www.h2othouse.com/html/used_greenhouses.html
Next, keep checking your local agricultural bulletins, newspapers and sheriff's auctions. These are likely places to find some good deals. The horticultural industry has a high failure rate therefore you are more than likely to find some auctions. You could get wild and post ads looking for a used greenhouse. Sometimes if people have not sold one after advertising a week or so, they give up. This also could motivate a seller who is still undecided.
Check out the bulletin boards at all your garden centers and Agway-type centers. It is a natural place to post used greenhouse equipment.
