Booper, SDA, thanks for your replies.

The humidity in the tank would continually drop from 69ish to 50 or even 45. After modification the humidity has been stable at around 72, as he still has shed.

My hygrometer is from exo terra. I have the probe secured close to the bottom of the enclosure. Any recommendations on a better one?

Going to watch that video. Thanks for clarification on hide and log as well...
