Actually the humidity during flowering needs to be lower, to prevent fungus / mold on the bud. I would say between 20% and 40% you are golden.
Lowering the humidity to reduce the chance of mold/fungus on the buds makes perfect sence.

im a newb so i would wait for a second opinion, but from what i understand you want humidity anywhere from 50-60% untill the last two weeks of flowering then you want to drop it pretty low like mid to high 30's but you wanna take it really slow. The drop in the humidity makes the plant protect itself with extra resin causing the final product to quite frosty.
you wanna keep the humidity as high as possible to reduce the salt levels in the plants tissue.
Seems like I heard this before. Sounds very feasable.

I have an AccuRite digital temp/RH meter and anything under 30% RH registers as "low", which is where it's at right now. They have been flowering for just over a week with a mid January harvest date.
