I'm working on building my boa a wooden 4x2x2 enclosure out of 3/4" oak plywood, I'm aware of most of the different heating options (uth, rhp, che, heat lamps) but I want to know what works for you. I'm not sure how well an uth will heat through 3/4" of wood, I thought about routing out some of the wood so it wasn't so thick to heat through. I'll probably use fluorescent lights for ambient temps, so for now I'm more concerned with my hot spot.

So, how do you heat your larger enclosures?
