Well, using just a red heat lamp I have been able to maintain temps at 88-92 degrees Fahrenheit for the hot spot and at 78-80 degrees for the cool side while the humidity is at 50-60. She has no problem eating or digesting her food and is very comfortable in her terrarium showing no signs of stress, (well she is still spooked out by my sister when she visits but hell, she scares me too). Anyhow, although all is well, I was recently told I should ditch the lamp and get a UTH. I was just wanted to hear your opinions on whether or not its a necessary change I should make? Also, if I do make the change, what kind of light should I use just for viewing her when she is doing her nightly exploring?
