40% humidity in the room. I haven't been adding a lick of fluid to the bator for incubation. Started that maybe two weeks ago.
In addition to recalibrating, you may want to check out Brinsea's website for an article on daily cooling during incubation. Their new incubators have the cooling ability and it is supposed to help in weight loss. I haven't used the automatic cooling yet on my Octo 20 because mine get cooled pretty regularly when I candle all the time.
