one week they be dry/ smokable,but really not anywhere near reached its peak, cough ya a lot have very very green smell and taiste,
two weeks they mellow out with great tiaste makes ya say yummy
and smooth to toke
and three weeks if ya can get that long of good wheather will insure you have a great smoke all around

you just want it in cool dry place for SLOW DRY out process,
leaves the thc behind when all the moisture evaporates.
slower and longer the better
peace
