okay no one responded to my post on another thread so i decided to make a new one... for as far as checking temperature in tanks go... i only need one thermometer that checks both temp. and humdity AND has a probe?? would a 2 in 1 thermometer/hygrometer with a probe be enough to check the temp of the warm and cool side at once?? where ideally should i place the thermometer and probe?? thankss
