on the hot side, the temp is 88-98 degrees, and on the cool side its 85-90 degrees. humidity is 40-50% throughout.
now i have two things that im' measing the temperature with. one is a digital thermometor thing that also measures the humidity and the other is like a thermometer strip. i just place them inside the cage on one side and on the other (not directly below the heat lamp, though).
