even though they may feel dry on the outside, though, they may still be damp in the middle. Curing them in jars distributes the moisture evenly and prevents mold when you burp them. Open them for an hour a day or so, stir the buds, and close it up again. It evens out the moisture and helps w/ flavor. When you seal them in there for a day, then open them, they'll feel damp again. Burp it for an hour, reseal it and go back the next day. It dries it out completely.
make sure the buds aren't packed too tight in the jars, either. They need to be able to breathe a little.
