[QUOTE=kitedemon;1959099]Where is the ambient air temps measured with and location?

The probe was placed on top of the hide on the cold side...80F this afternoon with a room temp of 64F. The probe read 92F when placed under the rhp.

Honestly, I agree with most of what you're saying, but they are improving ambients for me in my set up, and I'm quite pleased it. I think, also, that it needs to be mentioned again that I've got a herpstat thermometermaintaining things where I want them...a dimmer or low quality thermostat wouldn't cut it here.
