Hi, I'm new here, but was reading about the bubble wrap idea for the greenhouse. I have "rescued" an awful lot of bubble wrap from a number of places without spending a cent. I have plans to use it in a cold frame that I'm building from another rescued material. I don't know what it's called, but it's structure is the expensive greenhouse covering. This is a lot lighterweight and is made of plastic instead of acrylic.. If any of you have a Territorial Seed catalog, there is a cold frame in there that is just like what I'm building, and for a 10th or less of the cost. I have about 4 BIG boxes of bubble stuff and pick it up where ever I can.
Well, just my 2 cents worth
