Sounds like they might have gone into the jars too dry already.

Are the buds crispy/crunchy? If so, yes the humidity is the culprit.
canniwhatsis Reviewed by canniwhatsis on . Herb not curing Has been stored over three months now. Have my harvest in glass mason jars and vent daily. They still smell like a fresh mown lawn. The smoke is harsh with no flavor. I live in the desert so the humidity is very low. Could that be the problem? Rating: 5
