Genetics: GMO x Sour Dubb GMO, also known as “GMO Garlic Cookies” and “Garlic Cookies,” is a potent Indica-dominant hybrid marijuana strain made by crossing GSC with Chemdawg. This strain produces a euphoric high with mentally uplifting effects. Sour Dubb, also known as "Sour Dubble," "Sour Dubb Dawg," and "Sour Double," is a hybrid marijuana strain and a mysterious clone-only strain of unknown heritage. Sour Dubble is thought to be a cross of East Coast Sour Diesel and Sour Bubble. B.O.G. Seeds recreated Sour Dubble using Rez Dog’s Sour Diesel IBL instead of the ECSD and the results are very similar, if more indica-like than the original sativa-dominant hybrid. Dense buds with copious amounts of trichomes produce a pungent, sweet n’ sour odor and a strong diesel flavor with a sweet fruity aftertaste. The high of Sour Dubble is a nice blend of head and body effects.
