This is something I should probably know by now, but WHAT should be 90F when talking about the warm side...
The surface of the glass is MUCH warmer than the air temps...
Glass temps under the substrate in my terr are 100 even, and the air temps are about 90...I just got a thermometer with a separate sensor and was wondering WHERE it should be placed...down on the glass or in the substrate or what?
I've heard that it should be measured on the glass, but that doesn't make much sense to me as the subtrate temps would only be 80 ish...
So should I back my temps down to 90 glass and 80 sub/air...or 95 glass...85 air...
