The hides are different. The warm side is a plastic hide and the cool side is a simple plant like bush that came with my setup (zoomed premium snake kit). It seems to like the bush alot but it just seams cold to me. I do have a temperature controller on the UHC with the probe below the substrate on the hot side to make sure the temperature doesn't get above 92F. The thermometer i have placed in the center up high in the cage shows 80F some times 75F. But when i shoot the "cool" side on top of the substrate next to the snake it reads 71F. I do have a light on a dimmer for the "Warm" side to make sure the temperature stays 80ish throughout the cage. Now at night i turn the light off and the Temp drops. How do i maintain temperature at night above 75F? Should i use a heat emitter? I feel like i have a new born baby. I did alot a research before purchasing but actually maintaining temperature has me a nervous wreck. I don't want my BP to become ill.
