Aromatic chemistry
Yes — East Coast Sour Diesel is in the deeper lineage (via the Aspen OG side). Sharper diesel than Sour D, more head-up.
Jet Fuel is a sativa — head-up and uplifted in character, with the energetic profile customers expect from sativa-dominant flower. The lineage is Aspen OG × High Country Diesel.
Jet Fuel hits diesel up front, sharp citrus through the middle, and pine on the exhale. The smell out of the jar reads the same way — distinctive once you've had it once or twice.
Jet Fuel tests in the 18–24% THC range, which puts it on the higher end of the shelf. Customers with a built tolerance handle it fine; lower-tolerance customers should go a half-dose or less the first time.
Jet Fuel reads as a daytime strain — head-up and uplifted, the kind customers commonly reach for in the morning or early afternoon when there's still a to-do list.
