Thanks all. Temps are easily maintanable at a constant if I so desire. Humidity stays between 51 and 54 percent depending on relative humidity outside of the tank.
This is all due to the way I customized the lid I'm using. it is a frame from what used to be an all screen top. I removed the screening, and replaced 2/3 with 3/4 inch plywood. I drilled lots of ventilation holes. On the other 1/3 (the warm side) I used 3/4 inch plywood and cut a whole roughly just less than the size of the frame and covered it with screen.
No risk of burns. I have the heat lamp on a rheostat and it is a good 6 to 8 inches from the screen.
Thanks for all the input. So does anyone know if I go with this set up, if putting the UTH under the tank is a must??
