the point of air drying is to get a really slow dry because the plant "stays alive" for a quite a while afterwards anyway, the dry and cure is when most of the THC happens . So anything that makes the drying longer is a good, for example if you hang the plant whole the plant has more juices flowing for longer as they retreat into the stem this will make the drying that much longer. Other things you can do to get a good dry is to time your last watering and your chop based on your ambient humidity for example chop after a good watering if it's dry or chop dry if it's humid. Beyond that the most important thing is darkness and air circulation, you dont want mold getting in there. Hope this helps ! 🚀
