+1 to budsbunny's advice...curing time depends on the size of the nugs too...larger ones take longer. Give the larger ones about 7 days to hang dry, then put them in jars when the outside is dry and crispy, but the stem still has a little moisture. Some say to wait till stem snaps, others say wait till it just bends. If you are paranoid about mold, then wait till stems snap. Smaller buds might only take a few days to air dry, then they go into jars. Throw some stems in there with em to help them dry out a little slower. Make sure to open up the jars and let them breathe a little, and if you smell any mold (once you know the smell it is easy to recognize) then lay them out to dry immediately. But as long as you don't jar them too early, and you make sure to open the tops and let the jars air out, you will be fine.
