Sealed glass jars are the best. Mason Jars. Plastic isnt very good for storing for a long time.

Just make sure the bud is dry first, and put it in a dark place. Storing at room temps is fine, and so is cool. Just make sure it's not hot, or in light.

If your not sure about how dry the bud is, put in alittle bit of tissue to absorb any slight moisutre that could cause mold.
