im using a digital hygrometer/thermometer as you can see on the back wall of the tank in the fog pictures, im using a exo-terra utrasonic fogger, gets humidity up to 70% in no time with the top screen fully uncovered even, im going to pick up another hide soon and ditch the half log... im also planning on picking up a 40 breeder to accomodate a second ball python, planning on a female mojave like i said, also probably going to switch to cypress mulch soon... thank you for the kind words !
