Well then how do you increase ambient temps.
One thermometer is the round kind and the other one is just a metal one with the glass tube and murcury at the bottom?? They both read the same. I know people are telling me they suck, but the do seem to be reading well. I think my probe is maybe the wrong kind. The papers it came with say to place it on the window ledge out of the sun to read indoor and outdoor temps, obviously I'm not using it that way, but maybe this one really isn't meant for what I'm using it for.
