Yeah, Habitat would be a good place to start and there may be other places not too far away that sells seconds (wood, door, windows) and close-outs (other materials). You can also temporarily cover it with heavy guage visquene (sp?). That would get you through a year. Also pvc piping would work. That's the backbone of one of my "lean-to" greenhouses, and it is two years old and holding up well. I can perhaps help you plan a greenhouse if you want, since I have now built three of them, all different construction. You'll just have to promise to buy some plants from me.
