That's only for brick weed. Pour soda on it and it will get super sticky icky.if you find your bud is getting harsh to smoke and feels dry you can always put a peice of bread of orange/lemon peel in the jar with the buds just make sure to keep an eye and take it out before it starts getting any mold. basically the buds will pull the moisture out of the lemon or bread and "replenish" itself so eeverythings equal inside the jar.
Maybe we're moving too fast.
@Arteeb are you still smoking flower and not seeds and stems?
