The genetics of Grapefruit Diesel are probably obvious to connoisseurs of marijuana. Its parent strains are the sativa-heavy Grapefruit and NYC Diesel. Flowering within about two months, this flower gives off the unlikely aromatic profile mixture of spilled fuel and grapefruit citrus bite. However, it can be sweet on the tongue. Its effects are split between the mind and the body, resulting in a relaxing and sometimes even sedative strain that also provides a solid mood boost and bursts of energy in smaller doses. While it makes some users anxious, most will only suffer from the usual dry mouth.
