Sour Diesel Grow Timeline
Sour Diesel Seeds & Genetics
Genetics: Chemdawg 91 x Super Skunk | Breeder: Unknown (New York, 1990s) | Type: Sativa-dominant Hybrid
Sour Diesel emerged from the New York underground in the early 1990s, believed to be Chemdawg 91 x Super Skunk. Its diesel-lemon aroma and fast cerebral high made it iconic globally. Seeds are available feminised from multiple breeders. Autoflowering Sour Diesel suits northern climates. Our beginner cannabis growing guide covers all basics.
Indoor vs Outdoor Growing Sour Diesel
SCROG is virtually mandatory for indoor Sour Diesel - see our SCROG guide. Flip to 12/12 after 3-4 weeks of veg to limit stretch. Outdoors, it suits Mediterranean climates where it finishes in November. See our outdoor growing guide for season extension techniques.
Nutrients & Feeding for Sour Diesel
Sour Diesel has high nutrient demand throughout its extended lifecycle. EC 1.4-2.0 in veg, maintaining phosphorus and potassium with CalMag throughout flowering. Avoid cutting nutrients early - it builds resin into weeks 9-10. Flush 10-14 days before harvest. See our nutrients guide.
Common Problems & Solutions
Height management is the main challenge - use SCROG and bamboo canes. Powdery mildew risk in humid conditions; keep below 50% RH. Intense odour requires quality extraction. Some phenotypes prone to hermaphroditism - avoid light leaks and temperature stress.
Harvest, Drying & Curing Sour Diesel
Harvest when trichomes are 80-90% milky white to preserve cerebral character. Dry in dark ventilated room 10-14 days. Cure 4-6 weeks in glass jars - diesel-citrus aroma becomes more refined with extended curing. Full instructions in our harvest guide.
