This medical marijuana strain is a pungent hybrid that was created by crossing the famous bed time indica strain, ‘Granddaddy Purple’ with the most extensively smoked sativa strain, ‘Sour Diesel’. This is often confused with the craft marijuana strain, “Sour Grapes”, which was created by crossing ‘Sour Diesel’ with ‘Grape Ape’. Both these are different from each other and hence, the users who are intending to buy Sour Grape are recommended to inquire about the parent strains while buying. The buds of this plant are quite denser with purple colored undertones all over them. These indica-dominant buds would give the users with a sweet, sour and grapey flavor and would be more or less like that of a candy. The aroma that is being produced by this strain will also be sour in nature. In addition, we would get fuel-like and fruity undertones. The flowers will be chunky and will be covered with a thick layer of frosty natured trichomes. The effects of this strain are found to relax the muscles and would work fine for the users who are fighting muscle tension and stress.
