Brothers Grimm
Brothers Grimm is a legendary, foundational cannabis breeding collective founded in the Pacific Northwest, USA, in the mid-1990s. They are most famous for creating **Cinderella 99 (C99)**, a seminal sativa-dominant hybrid that has influenced countless modern strains. The original breeding project was spearheaded by a breeder known as **Mr. Soul**, who crossed a mysterious, potent female he called **Princess** with a male **Jack Herer** from Sensi Seeds. The result was a fast-flowering, high-yielding, and intensely cerebral strain that became a benchmark for quality. The collective operated with a philosophy of open-source breeding, sharing genetics and knowledge within the community, which was revolutionary at the time. After a period of dormancy following Mr. Soul's retirement, the brand was revived in the 2010s, with original genetics preserved and new projects undertaken. Their work is characterized by a focus on sativa-leaning plants with exceptional clarity, potency, and flavor, securing their permanent place in cannabis history.
