What Are Sour Diesel Autoflower Seeds?
Sour Diesel autoflower seeds grow into vigorous plants that race from seed to harvest. With autoflower genetics, they don’t wait on light cycles. Buds stack up fast, giving you earlier harvests than regular or feminized seeds.
Most autoflowers, including those we offer at Fly High Seeds, are feminized for greater consistency and higher success rate. Growers love them for quick results, bold flavor, and uplifting Sativa effects in every crop.
Lineage & Genetic Heritage
Sour Diesel autoflower traces its roots to the famous cross of Chemdawg 91 and Super Skunk, two parent strains known for unique traits:
- Chemdawg 91 – pungent fuel aroma and soaring cerebral effects
- Super Skunk – skunky sweetness and reliable growth patterns
The original Sour D appeared on the East Coast during the early 1990s, gaining fame for its sharp diesel scent mixed with sour lemon and citrus notes. It spread quickly through New York’s underground scene and later across the country.
Over time, it earned a place as one of the most iconic cannabis strains. Sour Diesel has won big awards, including second at the 1994 High Times Cannabis Cup and first at the 2004 Highlife Cup.

Yield Potential of Sour Diesel Strain Autoflower Seeds
Sour Diesel autoflower seeds may give rewarding harvests when grown in good conditions. Indoors, plants often bring steady results, while outdoor gardens may produce more under bright sunlight. This potential makes the strain appealing to both new and experienced growers.
Indoor vs Outdoor Yields
Sour Diesel auto seeds may yield 350 to 450 grams per square meter indoors, or about 1.1 to 1.3 ounces per square foot with good lighting. Outdoors, plants can produce 14 to 17 ounces each in sunny spots with strong airflow. This yield is higher than that of many other strains.
For better results, keep the soil airy, provide steady nutrients, and use low-stress training to improve light coverage. These steps support bud growth and plant strength. The yield of any crop, including hemp, can vary with the plant variety, environment, farming practices, and overall care.
Plant Height and Structure
Sour Diesel auto seeds may grow into medium plants with a classic Sativa shape. They develop tall branches, lime green leaves, and a wide spread. Indoors, they stay at a manageable height in tents. Outdoors, they grow taller under direct sunlight.
Give the plants steady airflow, enough space, and balanced feeding for strong growth. Use low-stress training to manage height and improve light reach. This setup helps the plants form dense buds during the flowering stage.
Growing Sour Diesel Auto Seeds

Sour Diesel is a 90% Sativa strain that may finish flowering in 9 to 10 weeks. Indoors, plants can yield 350 to 450 grams per square meter. Outdoors, they may produce 14 to 17 ounces each. To keep flowering on track, use steady light cycles, warm temperatures, and avoid plant stress.
Good airflow and balanced feeding help buds grow dense and strong. Watch the trichomes to find the best harvest time. The yield of any crop, including hemp, can vary with conditions, farming methods, and weather.
Indoor vs Outdoor Cultivation Tips
Sour Diesel has medium grow difficulty and needs steady care. Indoors, it grows best in dry rooms with good airflow, strong light, and a steady nutrient plan. In these conditions, it may yield up to 14 ounces per square meter.
Outdoors, this strain thrives in sunny, dry climates with 6–8 hours of direct sun each day. For more vigor, 10–12 hours is even better. Outdoor plants may yield up to 16 ounces each with good airflow. Avoid wet conditions to prevent mold and protect bud quality.
Germination Tips for Beginners
Sour Diesel seeds usually sprout in 5 to 7 days when using the paper towel method. Keep seeds warm and moist until a small taproot appears. Once sprouted, place each seed taproot-down into light, airy soil. Maintain temperatures of 70–85 °F and humidity at 60–70% to reduce stress.
Start seedlings under gentle light, then slowly increase intensity as true leaves form. These steps support strong early growth and healthy plants. Check the Fly High Seeds Germination Guide for more info.
Avoiding Common Autoflower Mistakes
Sour Diesel autoflowers need careful attention. They feed lighter than photoperiod strains, so too many nutrients can burn the plants. Too much water may cause root rot, so keep the soil airy. Transplanting adds stress, so place seeds in their final pots from the start.
Keep lights on for 18–20 hours a day to support bud growth. Don’t harvest too early. Watch the trichomes and wait until they mature for better potency and yield. These steps help you avoid mistakes and grow stronger, healthier plants. Results may vary with environment, farming methods, and weather.
