I have a 40 gal tank, screen top.
Substrate: Zoo Med's aspen snake bedding
Heat: one small UTH (came attached when purchased), one large UTH for 30-40 gal tanks. Small one is running very low for cold side, Larger running between low-med for hot side.
Water: Very large Petsmart style reptile dish (came with purchase) probably holds half gallon or so.
Humidity: Digital thermometer/Hygrometer says it 51%. dial gauge (petsmart) says it about 75%. both located closley, so there's another contradiction but I trusted the digital over the dial.
But the thermometer is telling me that the hot side is 105 and the cold side, where the probe is is at 80. I also get around 80 when I measure the temp of the cold side with the infrared. So only prob is my hot side not correlating.
