Dittos on the mason jar. Little space in there wont hurt it. After its fully cured try storing in the refrigerator in the jar(s). Take them out shake them around lightly, take the lid off and let them set till the jar comes to room temp about once a week. Never had any trouble using that system. Now you can get into trouble if you put it in the jars while its too green and dont burp it enough. If the stems are still pliable its not fully cured and should be burped once a day or you might get mold on it.
