Some last minute questions as I await the arrival of my new BCI (tomorrow).....

I have the quarantine tub setup w/ two hides and a water dish. It's been sprayed w/ PAM over 24 hours ago.

Humidity is around 65-70%. I had my hot side floor temp set to 88 degrees but I ended up bumping it to 91 because the paper towel substrates were only reading in the low - mid 80s. I know with other substrates, a snake can burrow and reach the floor but w. paper towels is there a different protocol here? Are those temps good?

Also, I put about 4 holes on all 4 sides. I would assume this is enough ventilation for him?

Any other suggestions are appreciated.
