Been doing the same method for 10-12 years now. I use a 10 by 12 room, completely dark. Keep humidity in the 50-60% range (aim for 60) with a small cool mist humidifier .usually takes appx 9-12 days depending on bud girth and moisture content to begin with. I’ve always given them some ice cubes (obvs when in soil) for the last day or 2 in complete darkness before chop. I even chop and trim with very minimal light. I then chop the whole plant and hang this way for 7-10 days. I remove large fan leaves and any useless trim . After 7-10 days I gauge the buds by feel and stalk dryness. And any big fat juicy buds that seem much more damp are removed and hung separately . When I feel I have close to adequate dryness I finish trim, then paper bag for appx. 24 hrs (sweating the buds a bit before they go into cure mode) watch carefully that last 24 and remove all that feel much drier and throw them in your jars. Then Jarred up (appx 75-85% full with small hygrometers) 60 days. Only had to use bovedas once and that was a screw up where way too much moisture was removed , even that crop turned out awesome surprisingly . I know you asked about humidity but I figured I’d give everyone my drying process I learned from an old timer about 15 years back , I tweaked it a bit but this tends to always give great results. Hope this helps someone
