Cold Frame

I have been dreaming of a passive solar greenhouse for a while now. I think the idea of a self sustaining greenhouse that would allow me to grow produce through winter would be wonderful. Problem is stuff costs money. So I decided to make a cold frame based on the same principles.

I will be using some old windows, scrap lumber, and left over insulation. I am going to build it at the base of our barn which has a block foundation and wall. I will paint the wall dark and cover it in some solar pool blanket I have access to. This wall and blanket will hopefully absorb and hold enough heat to keep my cold frame/mini greenhouse warm enough to grow greens. We will see. Pictures of the project will be coming as I progress.
