Thank you! It's good to be back.
I appreciate the advice, I'll set them up in something small and work up from there.
Thank you for getting back to me on the heat tape! I cant find opinions on this anywhere, just "this is what I do" sort of posts. I'll probably end up gutting the tape and reinstalling new/fresh tape to cover more of the enclosure, however it's nice to know that it's not a super pressing issue.
Thanks again!
