Why this one matters: hybrid genetics with a 15% THC ceiling and skunky/sweet-led terps. 9-10 weeks flowering, indoor or outdoor.

Amsterdam Seeds Company lists this at $23.95 — the lowest base price in the comparison ($30.66 floor). Pack options: 3-seed at $23.95, 5-seed at $35.09, plus larger sizes.

Smell-first: crack a jar of Purple Sour Diesel and the skunky diesel funk hits before anything else, with a faint sweetness underneath that keeps it from being one-dimensional. At 15% THC it sits in a moderate range—enough for a clear, uplifting session without locking you to the couch, which fits the 70% sativa lean in the genetics. Amsterdam Seeds Company built this as an autoflower, so the 9-to-10-week seed-to-harvest window is fixed regardless of your light schedule, making it a practical option if you're running a mixed tent or an outdoor patch where photoperiod timing is inconvenient.

300g/m² is a honest, mid-range indoor target—don't expect record-breaking weight, but don't undersell it either. Difficulty is rated moderate, so first-timers may want a simpler auto before attempting this one. Works well indoors or out.

Best suited to intermediate growers who want a fast-finishing sativa-dominant auto with a classic skunk-and-sweet nose.

Growing Purple Sour Diesel Auto

Purple Sour Diesel Auto is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 9-10 weeks with yields of 300g/m2. Plants typically reach 100-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Purple Sour Diesel Auto features a skunky, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Purple Sour Diesel Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
