I just put a smaller (27 gal) Exo-Terra together this week. Here's what I learned/did.
They can be tough to keep humid. I solved this by using Eco Earth, and covering 2/3 of the screen top with a piece of plexiglass. My humidity is just over 60%
I plan to use a Reptile Basics radiant heat panel and VE-100 t-stat for ambient temperature but it'll be after Christmas before I place that order. Until then a 60w CHE is keeping my hot side at an even 89, and my cool side at 75. The CHE and RHP work in a very similar ways, but the RHP is more efficient, safer, and gives a cleaner more finished look to your enclosure. I also installed a UTH to create a hotspot.
Since taking these pics I've gotten rid of the single CFL light, and replaced it with an LED strip to further give that "finished look". I know the snake doesn't need it, but it makes it nice for us people critters to view them. I can post a pic of it later if you're interested.
Hopefully this is at least quasi informative.
