Our take
Sour Diesel Auto brings the sharp citrus-and-earth character of the original Sour Diesel cut into a feminized autoflower that finishes in 9–10 weeks without any light-schedule adjustments. At up to 21% THC and a 65% sativa lean, it suits growers who want a lively, flavor-forward strain and enough yield to make the grow worthwhile. Manageable for intermediates; beginners will do fine with basic research.

Growing notes
These XL autoflowers stretch to 35–47 inches, so account for vertical space indoors. The F4 generation brings solid genetic stability across indoor, outdoor, greenhouse, and mixlight setups. Outdoor plants finish well in most US climates within the 9–10 week window. Feed moderately and watch canopy height — topping early can help manage size without sacrificing yield.
