I've made some similar to those, but I wrapped them in plastic. They make great lowland chambers.
Say Ozzy, when you were doing that, did you ever get problems with condensation dripping on the floor? I was considering making something like this but I thought it might be a little leaky.

No, I encased the whole thing with plastic. So when it dripped down it would just collect on the bottom. It would make a pool and that would further help with humidity. For ventilation I just cut two slits down the front, and then cut from slit to slit to make a flap. That was my door. It worked pretty good.
