Well that is one REALLY BIG enclosure, first suggestion would be a much smaller enclosure. And yes i to find lots of different temp ranges in different care sheets, but they are all close to the same. Lower 90's warm side and Lower to mid 80's cool side. But on the heating end, you need to ad some heat to the cool side in some form or another, but you also need to get the warm side warmer. I like underbelly heat a lil better personally since you dont have as many issues with humidity like with a heat lamp.
