9lb Hammer (also 9 Pound Hammer) was created when breeder Jinxproof crossed his favorite strain Gooberry with the TGA Genetics Jesus OG Kush member of the OG family. These strains combined to form 9lb Hammer’s intoxicatingly fruity blend of grape flavors and autumn-colored foliage. 9lb Hammer was so named because it allegedly felt like a heavy hammer knocking users out cold.
