I left mine in cold room, around 22°C-23°C with 60% humidity. Had fan blowing around them so there is some air circulation to prevent mold, but be careful not to have fan blowing directly on buds. That would dry them way to quick which result in harsh smoke. The drying took around 10-11 days and I was drying them without roots. You know it's ready when the stem snaps when you try to bend it. If it just bends, it's not ready yet. As for curing, I used Boveda humidity packs (62%) and left them in glass jars for 2 weeks before smoking. They continue curing even after that, but I don't recommend smoking it before those 2 weeks at least. For the first week of curing I opened the jars for 10-15 minutes to get rid of excess moist, but after that I just left Boveda packs to do the curing job :) other people might use different technique but this one worked well for me. :)
