Sour Jack is the cross of two classic sativa dominant strains. The parent strains are 'Sour Diesel' and 'Jack Herer'. The acute sour odor of this strain is the signature aroma of Sour Jack. This would give the users the blend of lemony and fuel aromas combined with the hints of menthol and pine. The taste will be nearly close to its aroma and is more or less like that of lemon soda.
