Btw, any cage with the sliding glass doors will allow you to "pop them out". the glass sits in tracks and you just lift one pane at a time and lift them out. You'll see what I mean when you put the doors in.
And, yea, in a basement, too tall a cage is more difficult to heat. I would stick with 15-18" high.
And the RHPs really do help with ambient temps - otherwise, my gtp's cage would not be warm enough!![]()
