I built an 8 x 8 x 6' high cattle pannel green house this fall and love it. I used combination windows from the Habitat store in Bangor for the doors at either end. I transplanted some lettuce into it from the main garden in early november, and it stayed green through multiple frosts until mid-December. No supplemental heat. I guess it's not technically a green house unless it has supplemental heat. It held up VERY well to hurricane Sandy and the other wind storms we've had this winter.(I just got it buttoned up and lashed down before Sandy arrived. I did not have to remove snow. As it heats up, the snow slides off, then where it touches the sides, it melts back from the walls. I don't know how it'll fare in a more snowy winter. The construction was real easy, so much so that I'm using the design to build a chicken tractor of the same dimension. Plan is to have 4 drop-down wheels, a raised insulated area (covered with tarp or corrugated roofing) at the back for roosting and nest boxes, with space underneath which could be fenced in for future brooding. The front end will use the full 6' height, and be covered by 4 mil construction poly in the winter, tarp only on top in the summer for shade. Access in front with a people sized door, and to the back area from both in front and back.Does anyone do greenhouse stuff as well? We are starting to get into the homesteading concept, attempting to fight back against the rising cost of feeding our family. As I mentioned in my earlier post, I am building the coop this weekend, including the greenhouse half. Any thoughts?
Are you planning to allow chickens to access your green house? How big are you going? If it's a permanent structure, you would benefit from a heat sink. I'm excited for your upcoming building project!!!
