I've thought about your post for most of the day and I keep coming up with the same conclusion - why use the foam? Unless you are striving for a "natural-appearing" environment such as vivarium folks have, why not just get cocofiber rolls and glue that to the back of the tank and raise the bottom with "egg-crate" panels used for florescent lighting fixtures? That's what I am planning. I think the point with orchidariums is to provide a certain moist environment. If you are after more than that, fine, but foam is not the only answer. Great Stuff is nasty. It is great () for insulating, but it is not aesthetic. Short of spray painting it, I don't know what you might do.
