my ambient room temp is between 75-80 degree. my uth does not have a thermostat and i will be sure to get one as soon as i wake up. i will also change his substrate to cypress mulch more than likely. Im getting a 40 gal tank tomorrow so ill be able to set it right this time with temp and humidity and all. so let me make sure i have this right for the hot side temp should be between 88-92 degree and cold side 78-82 degree. humidity should range between 40%-50% and when sheding around 70&. i am going with the cypress mulch more than likely. one more question should i have thermometers on both hot and cold side?
