Double Diesel is the offspring of the multiple-award-winning NYC Diesel and Sour Diesel strains, reportedly created by Southern Humboldt Seeds Collective (SoHum). This diesel double-down makes for a super-fuel flavor. However, this THC-heavy strain is said to also deliver sweet, earthy, citrusy tastes and aromas. The plant, available only as a clone, is simple to grow either indoors or outdoors with a high yield. Some growers report that it does best in a hydroponic growth medium. Double Diesel flowers in seven to 11 weeks, showcasing darker green buds with bright orange hairs.
