BUDWEEDSEEDS

Seed descriptions often include abbreviations that indicate how a line was bred. Terms used in cannabis genetics include F1 for the first cross between two distinct parents, IBL for an inbred line stabilized over many generations, and BX for a backcross to one original parent. True F1 hybrids tend to be uniform and vigorous, whereas later generations show wider variation. Understanding these labels helps predict how consistent a pack will be.
