Kinda weird since if you cured it correctly and it stays in a sealed jar it should not dry out past the original cure unless your leaving it out of the jar for extended times??? You take what you need to roll put the rest back in the jar sealed and back to a dark place should never really dry. If its crumbly just add the end of a loaf of bread to the jar and close. Check it every half hour the moisture in the bread will revive the bud but dont forget to check as overnight the buds can go soft again.
