My Tub Setup

[alittleFREE]

Aside from having to take the thermo out of the enclosure and adhering the wires to avoid an issue, I don't see any immediate red flags.

I think it might be because I haven't had my coffee yet, but this sentence is really confusing me. I'm not quite sure what you mean?

In that first picture though, it looks like the the enclosure is square and doesn't look long enough to provide enough space for a temperature gradient.

The floor dimensions are like 17 x 12 I think. I only have the heat pad under a little less than half of the tub.
