weed is at its most potent the day it was picked off the plant.after that it gets less potent. weed tastes horible when it hasnt been cured but weed that has been allowed to dry over an 8week period, ive never met a grower who has lasted the whole 8weeks, they normally give up after 3-4weeks, anyways the longer bud is left the better taste it gets but potency increase is bollox.
