Hoop houses need a beam going from one end to the other up top with supports on both ends .This prevents them from collapsing under snow loads.The other reason they collapse is people make them too wide (weaken the structure)Snow should slide off the sides.That's why I'm thinking of an A-Frame design. I don't want to come home one day to find my chickens crushed under the weight of snow on a hoop house dome.
I just got another load of pallets, so I would have enough to build an A-Frame out of pallet wood, but it would not meet my goal of being mostly transparent. Maybe I could cut out lots of slats on the pallets and open it up for sunshine, then cover the pallets with transparent plastic to keep the snow out. However, I'm thinking of just building an A-Frame skeleton with pallet 2X4's and covering the frame with plastic. Still considering my options.
