there are a lot of factors that come into play, typically its accepted that long and slow wins. did you hang the whole plant? it will take longer, is it rainy weather where your at? it will take longer, did you water prior to chopping? ittl take longer.
longer is usually better, it give the clorophyll time to off gas so the bud doesnt taste green. where i live i usually have to hang dry for a few days if not a week longer than i do in the summer, the temp and airflow and RH (relative humidity) of the room yuor drying in matter.
the generic answer ids typically 2 weeks. but thats just where you start from, its a guideline more than a rule. each plant and drying room and method yields different times. i know this wasnt too helpful bro, sorry, id say 2 weeks for a whole plant hang tho then see if the stem of a branch BENDS or SNAPS. bending means is still water in the stems, needs to hang longer. its gonna seem over dried. thats fine tho,. is just the outside of the bud thats dry at that point ususally, thats when jarring for a cure comes in. we make a vaccuum in the jar which pulls the remaining moisture thats still in the stem out thru the bud, bringing with it terpenes. making it smell and taste like our end result. dont rush it , you spent a long time getting them to the point of harvest, dont rush it now and ruin it bro. happy smoking
