I'm setting up two racks I purchased (AP 4xcb70 and RBI 4x32qt with a herpstat 2) and might get a baby rack way down the line.
I have a temp gun, as well as multiple acurite indoor/outdoor thermo/hydrometers. I am planning on setting one acurite up in each tub. However with bigger racks, I see a lot without any visable thermometers. Are there other methods of monitoring the ambients and humidity in the tubs with less total thermometers? My only guess is monitor the hot spots with the temp gun and otherwise keep the tubs set up identically to keep similar ambients/humidity, but I've also read about racks varying in temperature from top to bottom.
