after you put it into the cvault, did the buds feel soft/moist again? stick together? (more than you expect good weed to stick together) if so, remove for more air drying before placing back into cvault. otherwise should be okay.. ust needs time.
you still have to burp cvaults. the 2-way humidity pack does have upper limits as to how much it can absorb. if you hit an upper or lower limit, it will no longer control humidity in that direction. lower is much easier to notice, as the boveda packs will turn into a hard material inside. integra boost sucka dick, don't waste money with those. they don't control humidity anywhere near their stated RH %, unlike boveda.
you can weight hte packs. they should start near their listed weight "8g" / "67g" et al... if you know the jar is humid and the pack is no longer gaining weight, yo know that's as much water mass as it can hold. the weight change is simply water mass being absorbed or released.
