Fast drying by pointing a fan at your buds will "snap dry" them, locking away terpenes and cause a crappy hay smell.
Once locked away, they are locked away forever.
You certainly don't want any type of humidifier in the drying area, this can lead to mold.
Temps are ok, but humidity around 40% is much more bud friendly.
You just want a gentle breeze in the growing area to remove humid air, not some sort of cyclonic vortex causing accelerated drying.
Drying usually takes 4-10 days, depending on branch size and bud density. A longer and slower drying process is far better than a quick "snap dry" which just closes all the bud pores almost immediately, trapping the terpenes forever.
Drying in complete darkness is also important, any direct light on your buds after harvesting will cause cannabinoid breakdown rather quickly.
Hope this helps, Organoman.
