1. Glass terrarium 40 gallon with foil treated top
2. yes small uth under hide on warm side and lamp just off center for "cooler" side as well as ambient air temps.
3. 81.4F cool side and 93F warm side. humidity is currently about 55% but I just misted him an hour or so ago.
4. I have never used anything but aspen for substrate because I'm still kinda new to this and am afraid of the oils I've read about in other types of substrate.
