i could do that. i was just going to router in a piece of glass into the floor, that way I'm not losing any stability but I'd still want a good gap from floor of the enclosure to the bottom of whatever its sitting on if I do the UTH thing also. Never used a thermostat for reptiles before so not sure quite how they work yet. Would i need a herpstat 4 even if I'm only running 2 different types of heating units? I poked around that website before looking at the different models and such but got lost in all the features lol.
