Brothers Grimm Seeds is the American breeding team behind Cinderella 99, the compact, fast-flowering sativa that became a legend in the late 1990s before the house went quiet. Revived in 2015 with the original breeder, the catalogue centres on C99 and its descendants — Apollo 11, Rosetta Stone, Princess lines — mostly as regular and feminised photoperiod seeds.
