Get a hygrometer, aim for 4-7 days drying time, I like to dry at 40% RH. When you jar them, humidity in the jar should be 65%, and burped down to 55%. If it's >70% in the jar, leave them out for 12 hours, re-jar and check again.
I'm not sure if it's the best way, but I cured my last batch 2 months this way, I was very happy.
Yes hang in absolute darkness for 3-7 days. It helps to have a small fan moving the air in the space, but not blowing directly at them, as doing that will cause the surface of the buds to dry out while the center retains moisture. dry till the stem snaps rather than bends. To cure place in an airtight jar, a mason jar with rubber grommet is best. dont pack them in, drop them in. First day open the jar and gently agitate the buds every 6-8 hours. second day every 12 hours. after that once a day
