Popcorn buds, as the name implies, are buds just about or a little smaller than popcorn. These are usually B-grade buds that don’t have the bag appeal of large, lustrous A-grade nugs. One of the nice parts about popcorn buds is their intermediate position between budget cannabis and high-quality bud. The potency of popcorn buds should be on par with, if not slightly lower than, A-grade buds of the same strain (by the same producer).
