I do have an IR. Hot Spot top of the pyramid gets the hottest at 95 F. Everything else is in the 80- 90 range.
It is, though I didn't think it too necessary because the top of the substrate was getting warm enough. However, I have thought of ways to sneak a UTH in there and will probably do with the current set of fixes I'm doing to it now.
Yes I definitely know I have to take away to ability for him to get in there, but I wanted to address the cause first.
