Double Diesel is the sativa-dominant result of a cross between NYC Diesel and Sour Diesel. These plants are easy to grow and their green buds will give off a strong odor with some Grapefruit added in. The grapefruit notes overpower the taste, giving this breed a fruit flavor. Its effects are happy and uplifting, but not usually as lively as some sativas. Overall, it’s a good choice for a laid-back medicated time.
