I just set up my 1st tank a few hrs ago..I have a UTH on a thermostat set at 90 degrees on one side of the tank. The thermostat prob is between the UTH and glass under the tank. Using a screen topped 10 gal tank my ambient temp was low..So I hooked up a red/night Zoo Med light and my ambient it at 80. I have my thermometer prob set dead center of the tank about 4 inches from the floor on the back wall. Humidity is 49%, which is probably a little low, but the care sheet says 50 to 60%... So I'm close for Non-shed. Also have two hides one Warm one cool with a water dish in the center.. so the water is kinda on the UTH also, not sure if that matters?
Anyways, can I leave the Red/night light on 24 hrs a day for the heat? The room will have natural light during the day hours.
