yea you gotta hang them and do an initial dry for a few days for the outside to be dry, and then burping it in glass jars only evens out the moisture from the inside to the outside giving it the sweet smells. If you don't cure properly this wont happen...
If you put them directly in to jars from cutting your prob gonna have moldy buds, your gonna screw up your whole crop because you want to rush it, cut them down early and not cure properly.. ( or maybe not want to but if you have to do it its gonna mess it up smoke like shit and smell like earth)
