I'll explain my reasoning to you guys right now. In my climate it is well nigh impossible to grow anything but desert or plains plants outdoors. Our humidity is too low and our temperature are too high/low (yes both) to grow anything else. I figured that while a greenhouse may initially cost more it will eventually wind up costing me less than continuing to fabricate indoor grow spaces that can maintain certain conditions while saving space (I live in a 4 room apartment with my fiance). I have time to maintain a greenhouse, however, I don't have the immediate funds to purchase a new greenhouse. So I was thinking I could find plans to build one and get the materials a bit at a time so I would eventually have a full blown greenhouse. I need something sturdy. Winds here get to 60+mph almost every month and at the bad times get to more than 70. Temps here reach above 100* and have full southwestern sun.
