Donegal from Tweed is one of the original parent strains of cultivars such as OG Kush. With a very strong THC potency, the sativa-dominant hybrid strain is greenhouse grown in Smiths Falls, Ont., and then machine trimmed and hand groomed. This THC-dominant sativa has terpenes like myrcene, caryophyllene and pinene to thank for its subtle scents of hops, cloves and pine.
