really depends on your humidity level, temperatures, and whether you plan on moving the buds to paper bags after hanging.
to give you some reference, i hang as branches in a room @ ~50% humidity for 3 days
move to paper bags, separating the buds with layers of shredded paper lunch bags, for 2 days
then jar
you might need to go through some trial and error to find what works for you
a dehumidifier really helps to control the drying humidity, so you can fine tune it to work for however you want to do it
including hanging the whole plant
