Mike was talking to a friend about building the greenhouse. His buddy asked him what size and, when Mike told him, he said come on out to my place I think I have enough trusses for your roof! He did! Plus he gave Mike enough fiberglass roofing for the north side of the roof. We had some windows from remodeling our house, our contractor neighbor had broken a corner of the flange on a new glass sliding door and gave it to us, another friend gave us 2 glass sliding door panels and we bought 1 used window for $15.00! All the glass is insulated. The total cost of the greenhouse is $270 plus whatever the clear ridged greenhouse roofing for 1/2 the roof will be and OSB for siding the north side. The greenhouse is 10 x 18 feet. I think we need to have a bar-b-que for all the people that have helped us so much!
