Why didn't you calibrate?
They are plastic thermomerer hydrometer combos. I looked into calibrating the thermometer portion and found out that they could not be calibrated. I guess i got sidetracked getting super creative to figure out how to calibrate the temp on the two bators i never went back to figure out how to do humidity. They both read pretty close to each other, and i see posts with ppl running no water to 75% to 80% humidity the whole time i figured it cant be that critical.
