hi everyone, i just got my first ball python and am having some trouble regulating temps and humidity. my bp is about 2 1/2 feet. i have a 20 gal long tank, 2 hides (they dont match but im going to get matching ones as soon as i can), a ceramic heat emitter, a heat pad, a thermostat and a digital thermometer/hygrometer. i got the reti temp 500 thermostat which supposedly can control 2 heating devices at once but the problem is there is only one control for both of them. my temps are currently 75 and 95 and seem so always be about 20 degrees apart instead of ten which i understand is ideal. also my humidity is at 45% even with a damp towel over the top of the screen. im using aspen substrate but im thinking about switching to cypress mulch. i will post pics of my setup when i can but i have one hide on each end, the water bowl in the middle and the main thermometer is on the cool end and the probe is stuck to the glass directly over the heat pad. any suggestions would be appreciated!!
