There is no set exact time. Tempature, humidity and air flow are some of the most important things to consider when hangin the plants to dry. Size and moisture level of the buds are considered in the hangin time too 5 to 10 days hangin time is normal
Very true, good idea to buy a barometer to tell ur humidity. and stray away from a fan but make sure the air is flowing without any un filtered air from the outside.
