Brothers Grimm
Brothers Grimm Seeds was the Canadian breeding project run by Mr. Soul and partner that released Cinderella 99, Apollo 11, and Genius through the late 1990s, then shut down in 2002 after personal circumstances forced the principal breeder out of the public seed market. The original Cinderella 99 line was one of the first true sativa hybrids selected for indoor commercial yields rather than landrace-purist preservation, which made the strain a foundational input for dozens of later Pacific Northwest crosses including Cinex. Brothers Grimm relaunched in 2017 with Mr. Soul returning to active breeding, releasing updated versions of the original catalogue alongside new lines that draw on archived mother stock preserved through the dormant years. Pack runs from the relaunched program are small, sold through a short list of verified retailers, and tracked closely by preservation-focused growers because the original C99 line has been heavily counterfeited. For collectors the Brothers Grimm name carries one of the most-tracked breeding histories in North American cannabis.
