What I can to is build a square of of plexi glass drills holes enough for the humidity to leave the square, and simply have it open for access. That way she cant interact with it.
While under tank heaters are good for belly warmth they can also burn the snake. Not to mention without a heat lamp, she cannot bask. I feel she can better thermoregulate by having a basking surface under a heat lamp, a hide underneath if she wantws to be hidden and warm but not as hot as if she were basking, and a cool side. I feel that provides a better gradiant that youll find with an UTH.

Again my heat lamp is not what ive been asking about. Ive been trying to determine. Whether my humidifier is safe to have for her. and if her having access to it is the only problem here, and I have a soultion for that as I stated, than quoted in this upper part of this post. Than case closed. IM satisfied with using it.
