Spec sheet first — strain: indica, seed type: autoflower, THC: 20%, yield band: low, environment: indoor or outdoor.

Smell-first: crack a jar of Crown OG Auto and the room fills with dense pine resin and that sharp, unmistakable skunk funk Amsterdam cultivators spent decades refining. This 100% indica autoflower from Amsterdam Seeds Company pulls 20% THC with CBD sitting under 2%, so the effect is squarely sedative — good for winding down, not for a productive afternoon. The 8–9 week flower window makes it a practical choice for Canadian growers squeezing in a late-summer outdoor run before temperatures drop, and indoor growers running perpetual cycles will appreciate how predictably it stays on schedule.

Yields land around 300 g/m², which is honest for a moderate-difficulty auto — not record-breaking, but consistent enough that you're not gambling a full tent on it. Feeding schedules need some attention; neglect during the stretch will show up in final density. Best suited to growers who've finished a few autoflower runs already and want a straightforward, hard-hitting indica without chasing anything exotic.

Genetics & Lineage

Crown OG Auto traces its genetics to 100% Indica (Amsterdam Seeds Company). This indica-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Amsterdam Seeds Company, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Crown OG Auto delivers THC levels of 20%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Crown OG Auto

Crown OG 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 8-9 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 40-50% 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

Crown OG Auto features a pine, skunky terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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, Crown OG 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.
