Howdy BR2K, I keep both the trim and bud sealed in glass jars in the refrigerator while they cure. The cooler temperature (around 42° F) does not seem to adversely affect the curing process and defiantly helps to keeps mold and fungi under control. I, also, use smaller jars (8 to 16 ounce size) just in case an unwanted growth does get started, I will not lose as much. I do use the quart size for the trim (sealed and also in the fridge).
