You just need to open the jars long enough for the gases to escape and to change the air. If they are packed in the jars tight, you might want to lay them out on a tray for a few minutes, then back into the jars. I like to smell mine as soon as I open the jars. At first the will smell odd but as they cure that smell will be replaced by the smell of good, cured bud. Have you taken a taste yet?
