El Chapo is a sativa-leaning hybrid cannabis strain bred from a Sour Diesel IBL and Karma Genetics’ Headbanger, known for an extremely gassy, sour aroma and a strong, focused high. It was selected in North London in 2015 by Sour Genetics, who called it pheno #1, and was later released as seed through The Plug Seedbank. Users describe a clear, upbeat head high that gains body weight from the Biker Kush in Headbanger.

Where El Chapo Comes From
El Chapo is a UK strain with a clear paper trail. According to the breeder description carried on SeedFinder, Sour Genetics selected it in North London in 2015, where it was known inside their circle simply as pheno #1. It made its name on the UK scene before spreading further afield.
The cross pairs Sour Genetics’ Sour Diesel IBL, a line the breeder says was selected from Rezdog’s 2005 East Coast Sour Diesel release, with a chosen male of Headbanger from Karma Genetics. Headbanger in turn carries Biker Kush, so the breeder summarizes El Chapo as roughly 75% Sour Diesel and 25% Biker Kush. Leafly gives the same parents and describes the strain as a collaboration between The Plug and Sour Genetics.
The Plug Seedbank in Barcelona later made feminized S1 seeds of pheno #1 available, which is how the strain reached growers outside the original circle. Leafly lists El Matador as one of its offspring.
El Chapo Effects: What It Feels Like
El Chapo has a smaller review base than the big American strains, but the reports point the same way. Leafly reviewers most often tag it focused, followed by euphoric, relaxed, uplifted, aroused and energetic. Leafly’s description adds that the Biker Kush in Headbanger gives it a heavier feel than a straight Sour Diesel.
In practice that suggests a fast, gassy head high that sharpens attention and lifts mood, with a body component that keeps it from feeling too racy. The breeder calls it a heavy hitter. That makes it a better match for people who already enjoy strong diesel strains than for first-timers. Start small and let the first puff settle before having more.
El Chapo Terpenes, Aroma and Flavor
Expect gas above all. The breeder describes El Chapo as the epitome of gas and sour and warns that its odor is extreme. Leafly calls the aroma gassy with fruity undertones, and its reviewers mention diesel, citrus, sweet and herbal notes, with a stray mention of grape.
No terpene lab data is published for the strain, so we have not listed terpenes. The sour, fuel-heavy profile is consistent with its Sour Diesel majority.
Side Effects and How to Use El Chapo
Leafly reviewers have not reported many negatives for El Chapo, but the usual effects of a potent diesel strain apply: dry mouth, dry eyes and, at higher doses, a racing or anxious feeling. The smell is also a real consideration, both for growers and for anyone storing it at home.
If you are new to El Chapo, start with one small inhalation or 2.5 mg in an edible and wait before taking more; see our dosing guide.
Do People Use El Chapo for Medical Reasons?
The few Leafly reviewers who mention health reasons cite low mood, anxiety and inflammation. That is a very small sample of personal reports, not medical evidence, so talk with a clinician before using cannabis for any condition.

Growing El Chapo
- Flowering: 9–10 weeks
- Yield: Large
- Height: Medium to tall
The breeder lists a 9 to 10 week flowering time, medium to tall plants, a large yield and hard, compact buds, and SeedFinder’s summary gives about 67 days. The breeder advises a light feeding program and multiple toppings for the best results, and says the plant does well in any medium. Odor control is essential. Outdoor growers in the Pacific Northwest should note that a 9 to 10 week strain finishes late, so dense colas need airflow to avoid autumn mold.
Home-grow rules depend on the state: adults can grow at home in states such as California (six plants per residence), Michigan (12 per residence) and Oregon (four per household), while Washington and Illinois allow home growing only for registered medical patients. Check your state in our cannabis laws by state guide before you plant anything.
