Welcome!

A digital thermometer/hygrometer makes everything sooo much easier. I've found them at Lowes and Walmart. Its well worth the $12-$13 bucks. If you have a screen lid and haven't already done so, take tinfoil and cover all but a 1" strip on both ends. This allows air flow through the tank and helps maintain humidity and heat. Try to get your hot side about 90 degrees and your cool side about 80 degrees. A couple degrees off in either direction is fine. Alot of people will tell you to mask off 3 side of your tank for security. When I use to keep my bps in tanks I never did this. They still ate and didn't stay in their hides all the time. If your bp refuses food and stays in his hide all the time you might want to consider this. As far as humidity goes, around 40%-50% is what I keep mine at and its been fine for over 13 yrs. They eat ,shed and breed just fine.

Good luck and never stop researching.
