Thanks Ken, I see I can buy the material in bulk at a few places I'll have to look into that. A few more questions. I assume you have the clear? I assume also that I'd have to drape it over the outside of mine and then anchor it somehow. I think this is what I'll go with. I'm going to have to make sure it's big enough since my greenhouses are 10W X 13L X 8H - https://www.amazon.com/dp/B003TQMCMQ/
