Double Diesel
Double Diesel skips the regular pump. It's two grades of fuel in one tank.
Southern Humboldt Seeds Collective is credited with the cross: Sour Diesel x NYC Diesel, a mostly sativa pairing of two cornerstone Diesel lines. It's listed as a clone-only selection, and it has put in work as breeding stock, sitting in the family tree of Sour Tsunami, the collective's high-CBD cultivar.
The nose is a full fill-up. Pungent fuel hits first, then grapefruit and lime cut through, with sweet, earthy notes and a faint woody exhale behind them. Flowers show lime green under a sugar-frosted coat, with vivid orange pistils.
The breeder describes a fast-acting cerebral rush that can spark creativity without overwhelming physical fatigue. Grower reviews line up, pointing to an energetic, focused, creative head, with dry mouth, dry eyes, and occasional paranoia on the downside. Listed THC runs about 15% to 22%. The speed is in the onset, not the number. The to-do list can get a second look. The sketchbook can come off the shelf. The couch can wait its turn.
Double Diesel grows like its parents drive: tall and in a hurry to stretch. Grower reports describe a lanky, vigorous frame with good internode spacing that takes training easily, and an uncomplicated run overall.
Flower takes 9 to 10 weeks, and outdoor plants finish by mid-October. Yields are described as heavy indoors and out. Hydro runs are reported to give dense, resin-heavy tops, while soil brings a slightly sweeter finish.
Sourcing is the catch. The original is listed as clone-only, so seed packs under this name come from other breeders. Check the lineage on the pack before you pop anything, because not every "Double Diesel" seed line is Sour Diesel x NYC Diesel.
