RH is relative to temperature. It is not a measurement of how much moisture is in the air. At lower temps 60% may not produce good sheds at higher temps lower can.

A huge number of keepers freak out about bulbs "sucking moisture from the air" when in fact they are not changing it at all. The higher air temps can hold more water not less. The drop in rh is from increased ambient temps and is unrelated to how much water is in the air.

I have day ambient air temps of 84 degrees I keep the rh at this temp about 45% I have never had a poor shed. If you have 45% at ambient temps of 75% you will get bad sheds.
