Sour Diesel’s energized and positive high makes it easy to see why the strain enjoys popularity. It has spawned popular and flavorful strains like Sour Tsunami and Sour Jack and inspired strains like NYC Diesel, which imitates its unique taste. It’s as enjoyable in lively social situations as it is when used alone, and its combination of physical and mental effects makes it versatile enough to suit the user’s purpose.
Sour Diesel, sometimes abbreviated as Sour D, is an extremely popular strain, distinguished by the fuel-like chemical smell of its flowers. It has a mostly sativa head high with some subtle physical indica relaxation, making it popular among recreational and medical users alike. This is a potent strain, with a THC content that had been measured at 65%.
Although a definitive agreement on its original genetic makeup doesn’t exist, Sour Diesel’s popularity has made it the subject of much speculation. Some believe that true Sour Diesel was derived as a distinct phenotype of an original strain simply named Diesel. Others say that it was a phenotype of Chemdawg that leaned more sativa than indica. Still others claim that it was a cross of Chemdawg and Northern Lights, or perhaps Chemdawg, Northern Lights and Skunk #1.
Sour Diesel has round, medium-sized buds with leaves that appear yellowish-green. Red hairs called pistils, structures that operate to catch pollen from male plants, contrast with the densely-packed leaves. When properly cured, the flowers are somewhat sticky — the dusting of trichomes is not as immediately obvious as it is on more resinous strains like White Widow. Nevertheless, breaking open buds reveals trichomes coating the insides of the dense flowers. The buds have an overpowering smell that, true to this strain’s name, is very similar to gasoline. The odor also has some hints of orange. Breaking open or grinding the buds intensifies this scent, and adds components of musk and pine sap. Sour Diesel has a notoriously harsh, acrid smoke that can cause users to cough or make their sinuses water.
The high from Sour Diesel comes on users quickly in the form of a warm and pleasant head rush. An uplift in mood may be noticeable as well. Users may feel chatty if surrounded by others or somewhat introspective if enjoying the strain alone. For many, this soaring high is partially anchored by a slight feeling of physical relaxation. That said, a body stone that leads to full-on couchlock is rare. Its tendency to lead to associative thinking may provoke a bit of creative inspiration. Fans of the strain also describe relief from troublesome aches and pains. Sour Diesel’s combination of mental and somatic effects may also make it a potent aphrodisiac in certain situations. As such, users — especially those with a lower THC tolerance — should adjust their intake accordingly. Sour Diesel has an average-length high that lasts about 2 to 3 hours.
The plants are more characteristically sativa than indica, with a tall, spindly appearance and large spaces between flowering nodes. Plants can grow to be over four feet tall, with their height increasing exponentially during the flowering stage. Sour Diesel flowers within 10 weeks when grown indoors and around early November when grown outdoors. It has a moderately high yield: growers can expect between 42 and 56 grams (or between 1.5 and 2 ounces) per square foot of plant.
