Too lazy to do the real quote, but the OP said....
Finally, I put a screen top on the aquarium and put two heat lamps on top, one on the cool side, one on the hot side. I let the hot side lamp heat up and with two digital thermometers with probes, watched the temps, hot side was at a constant 90, cool side read 82, and digital hygrometer was at constant 52%. I also have fish tank thermometers stuck to the back of the aquarium about 2 inches above the ground on both sides which measured same temps as probed thermos.
