Price range: $34.99 through $109.99
Cultivation Notes:
Sour Diesel Auto completes its full cycle in 65 to 70 days from seed, reaching 35 to 47 inches indoors and 39 to 55 inches outdoors. Its Sativa lineage gives it a slightly more open, stretchy structure compared to most autoflowers, which works in its favor for airflow through the canopy. Indoor yields can reach 1.6 to 1.9 oz/sq ft, while outdoor plants commonly produce 8 to 11 oz per plant under good conditions. It flowers on its own schedule with no light cycle change required, making it well suited for perpetual indoor grows or outdoor runs where timing flexibility matters.
Additional Info:
Growers commonly associate Sour Diesel Auto with an energizing, focused character that reflects its 60% Sativa makeup. The flavor carries pine, citrus, and diesel notes that are consistent with the original Sour Diesel profile, and the terpene presence tends to be strong throughout the grow. At 24% T#C it delivers solid potency alongside that classic Sour Diesel nose. It adapts well to both indoor and outdoor environments and is a natural fit for growers who want a recognizable, pungent Sativa-leaning strain without committing to a full photoperiod timeline.
This seed was developed by a trusted member of the Triangle Seeds Breeder Network, ensuring top-tier quality and genetic integrity.
Frequently Asked Questions
Is Sour Diesel Auto a Sativa, Indica, or Hybrid?
Sativa Leaning Hybrid
Is Sour Diesel Auto an Autoflower or Photoperiod strain?
Sour Diesel Auto is an Autoflower. Autoflower varieties flower automatically based on age, usually finishing 9 to 12 weeks from seed regardless of light schedule. No light timing required — they're ideal for new growers, fast turnarounds, and growing indoors year-round. Photoperiod varieties flower when the light schedule changes (typically 12 hours on / 12 hours off). They take longer but give you more control over plant size and yield.
How long does it take Sour Diesel Auto to grow?
Autoflowers are the fastest path from seed to harvest. Most finish in 8 to 12 weeks total from germination, regardless of light schedule. Because they flower based on age rather than light changes, there's no separate vegetative phase to manage. Just plant, provide consistent light (18 to 20 hours a day works well), and let the plant do its thing. Check the strain details above for specific timing estimates, and visit our growing guide for tips on getting the most out of your grow.

How do I germinate Sour Diesel Auto seeds?
Autoflowers need a slightly different approach because their roots are sensitive to transplanting. Start with a 24-hour soak in a hydrogen peroxide solution (1 part 3% H2O2 to 6 parts water) to boost germination. After soaking, plant the seed directly into its final container (3 to 5 gallon pot) about half an inch deep — do not use the paper towel method or start in a small pot. Spray the area around the seed to keep the soil moist, but do not soak the entire container. The key with autoflowers is to never transplant them.
