Holy Grail Kush is a newer strain created by seed breeders DNA Genetics and Reserva Privada Colorado. It entered into the Seed Company Hybrids category at the 2011 High Times Cannabis Cup. As the offspring of multi-award winners OG #18 and Kosher Kush, it’s no surprise that Holy Grail Kush came out on top and is said to have nabbed the competition’s first-ever perfect score.
