I've been reading through so many of these wonderful posts and getting great ideas. I hope I'm not asking the same ol' questions.

What I have and want: I have a home-built, 10x10 (roughly) metal shed that I want to convert it to a GH using reclaimed windows. I want to use it for seed starting and winter protection for herbs/veggies (if possible). I don't want to run electricity out there.

Environment: I'm 1/2 way between College Station and Houston, so we get pretty darn warm, and it gets fairly windy, esp. with the storms we've been having. We have a few freezes and frosts during the winter, but nothing like snow.

So my questions:

1. Terminology - If I don't have electricity out there, is it considered a coldframe? Would it be using passive-solar heating?

2. Strength - How do I tell if the structure is sturdy enough to support windows instead of metal sheets?

3. Tin Roof - Would it's current tin roof get too cold in winter, or too hot in summer? Or would it help keep it from getting too hot in summer?

4. Window type - While "window shopping" at Habitat for Humanity, I've gotten different advice to using double-glass (insulated?) vs single pane. Could someone with experience explain pros and cons in layman's terms to me?

5. Flooring - It currently has a raised wooden floor. I'd rather not have to look at what is under it (copperhead den?). Is it possible to leave it? Should I put tile or pavers on it, or would that just trap water in there? Perhaps linoleum or vinyl flooring would be better?

I really appreciate any help! I know I'll make mistakes, but I'd love to learn from your experiences.

Ours also has the wooden floor and I think pavers would just create places for moisture to rot the floor. The linoleum may work if you can figure out a way to get it to drain properly.

I'm attempting to post a "before" picture of said scary shed.
