During the first week, you'll want to burp your jars twice a day - take the lid off and leave it off for a couple of minutes (I will even shake the jar a bit to get more air movement). Feel your buds, too... if they feel soft, they're not dry enough (the buds can and often do take in moisture in this process). You'll want to take them out of the jar and spread them on a drying rack or simply put them on a plate and leave them again in a dark place to dry out a little bit more. You can also simply leave the lid off for a day, sealing it back up the next day.
After the first week, you'll only need to burp them once every couple of days... in about 2-4 weeks, they should be cured enough to give a good smoke although some people will cure for 4-8 weeks and SOME strains need 6 months... only a taste test will tell you how long to cure yours!
Good smokes!
