I probably shouldn't have mentioned 'packing' in a cano thread. It was more of a general comment on the super fine powder where the particles are small enough to get blown through any screen, and some people pack a whip bowl so the herb will stay put in one of those downward angled box vapes like the Vapor Bros or VaporCannon. I sometimes end up with some of this stuff that's practically 'dust' in an old bag of mid grade.
