I have a 40 Gallon tank heated with a CHE on a stat and I’m not sure if my temps are okay. I have a piece of driftwood in there and the top end is maybe 15 inches from the bulb, which is what i have my probe fixed to. I have the wire glued to the branch so the probe is suspended under the bulb. The top of the branch gets to around 86 degrees but the substrate temps and only 79-80 in few spots. Is this okay since my snake can climb the branch to thermoregulate properly or do i need to move the branch and try and get it more consistent. My other concern is the screen lid under the bulb reaching 120+ degeees and my snake burning herself on it.
