Originally a mysterious strain of heritage, Sour Dubble is thought to be a cross of East Coast Sour Diesel and Sour Bubble. B.O.G. Seeds recreated Sour Dubble with Rez Dog’s Sour Diesel IBL rather than the ECSD and the results are extremely similar, if more indica-like than the original sativa-dominant hybrid. buds with copious amounts of trichomes create a sweet n’ sour odor and a strong flavor with a sweet fruity aftertaste. The high of Sour Dubble is a nice mix of body and head effects.
