Grape Krush is a cultivar bred by DJ Short of Old World Genetics. The strain is known for its “crinkly” leaves, which are nothing to be concerned about when growing. In fact, the “mutation” shows that you’re on to the correct cultivar. A descendant of Blueberry and of Haze, there is very little additional, reliable genetic information on the breeding of Grape Krush, except that its morphology suggests that it is a true Sativa/Indica hybrid. The cultivar will flourish in either indoor or outdoor gardens. Growers can expect flowers to bloom in as little as eight weeks, or in early October in the Northern Hemisphere when raised outdoors.
