Rainbow Sherbet 11 is a hybrid cannabis strain, but its exact genetic lineage might not be publicly available or well-documented. Cannabis strains are often created through crossbreeding various parent strains, and sometimes breeders keep their specific crosses proprietary. Without specific information from the breeder or detailed documentation, it may be challenging to determine the exact crosses that resulted in Rainbow Sherbet 11. However, Rainbow Sherbet strains typically have genetics from Sherbet and Rainbow Kush or other similar strains.
