You're going to really enjoy that T10 and herpstat. Most definitely easier to maintain than glass in my experience.
What I've found so far is that shorter enclosures are easier to dial in initially with RHP but can have a more dramatic gradient depending on the room temp. Fiddling with my 2' tall cages I can get the temps I want but the hot spot is on top of the shelf at 93-94 and the entire floor area is in the 83-79 range. Not terrible really, and I've been toying with the idea of more of an ambient temp overall with some micro climates within that. We'll see how it goes. My thinking is that they can handle a little cooler temps better than too warm of temps so I'm erring on the side of cooler.
The puzzle is never complete here and I keep adding pieces to the damn thing so who knows if it will ever come together. If the critters are thriving and I'm learning then I don't see too much of an issue really.
