Need Temperature Gradient Help!

[RoyaLoveRay]

I didn't think about that. Thanks for letting me know.gonna grab a heat gun later on in the week. is there any way that I could make the cooler end cooler whilst keeping the hot side at the desirable temperature? I was thinking about putting small holes in the cool side of the vivarium but I'm not sure

If I may... you're not likely to have a problem with the cool end of the viv being too warm. If anything, one has to make an effort to keep the ambient temperature of the whole viv high enough. If the cool side is too cool, your snake may become sluggish about feeding. Temperature drops are useful for breeding, though. I take it you are not preparing to breed ball pythons yet, as this is your first?
