Everyone like tells me different info on humidity. Drsfosterandsmith, RalphDavis, RoyalConstrictor, everyone has different (widely varying) humidity recommendations. I can never figure out one to follow. :/ What I've been reading is the general rule of thumb is never drop below 50% around 70%-80% during shed, and higher when gravid. Is this right? Cause I mean, it DOES fluctuate through the 60%'s.
