Ummm .... my hygrometer is being calibrated now .... I should have done this before, but for some reason I thought that I needed an accurate hygrometer to measure humidity, and I didn't even think to calibrate the one I have.What is ambient humidity? I run dry (28%) in my LG, but AC size is your best bet.
Just popping in....so far I have two of three hatched.....Tiny little silkies
