We just bought most of the materials to make a 20' long cattle panel hoophouse described in another thread. Without any luck, I've searched this website and others for how to properly orient a hoophouse with respect to the sun. I know I need to find "Solar South" which is different than "Magnetic South". But after that do I face one end of the hoophouse to the south or do I face one long side to the south? I have an wide open backyard without any trees to deal with. My uneducated guess would be to orient one end to solar south so that the sun shines in the east side in the morning, in the top at midday, and in the west side in the afternoon. But I can find nothing that tells me that. I figure the downside for this orientation would be if I'm using the hoophouse in the wintertime, the sun will be much lower and a lot of its rays will be blocked by the plywood end. Any experts out there?
