Hi guys, I have a few questions for, each kind of off topic.

1. Is it normal for young BP to stay in hot hide all day (possibly all night)? He has the same cave hides on each side in a 20gal viv, so I don't think security is his issue.
His temps are 76-78F (cold) and 86-90F (hot)

2. Any tips on how to keep tank humid? I'm using Forest Floor cypress mulch and he does have a heat lamp on top in addition to UTH. I spray the tank 2-3 times a day and still doesn't seem to do the trick. Also, any suggestions for an accurate hygrometer would be great,

3. Tips for feeding a problem feeder?

Thanks for the help!
