should I insulate the basement walls with spray foam

The basement is very humid in the summer and ice cold in the winter so I was thinking about insulation. The basement is so small that I can't afford to loose much wall space but I was thinking maybe 1" of spray foam would help with both the cold in the winter and the humidity in the summer? The walls are stone so spray foam would be a lot easier than rigid board and I think it would seal up the wall better for moisture. I haven't looked into code requirments yet but I'm sure there are some.

Technically, I don't see why not.. At 5 bucks a can, the cost may be prohibitive and it'll look like the original BLOB took up residence in your basement. How much square footage do you have? May be cheaper (and prettier) to frame a little away from the uneven walls and stuff fiberglass in there. Finish off with drywall.
