I just purchased my baby BP (Zeus) a couple days ago. I currently have a 10G Terrarium with mesh lid and clips with carpet liner, tub of water, a hide, a humidity/temperature gauge from zilla, an UTH and a heat lamp that is kept on top of the cage. I understand I need to purchase a thermostat to correctly monitor the temperature of the UTH. I've done some research to try and set up my Terrarium however, most do not answer my questions so I have a couple.

1. I recently purchased some cypress mulch, is it required to have both the carpet liner and cypress or can I just use the cypress ?

2. The humidity/temperature gauge is somewhat accurate, however, I have read that an accurite digital thermometer is better so I should purchase 2- one for cool and hot side of the tank correct ?

3. I have heard that Terrarium's do not hold humidity that well, however, the sticky thread that had a tutorial for glass tank setup is currently down so what is the best way to keep humidity within the tank ?

I'm very excited about my first BP purchase and I treat it much like a baby lol. Any help would be great
