The specs in one line: 22% THC, <2% CBD, 8-9 weeks flowering, 500g/m2 reported. Best indoor or outdoor. moderate grow.

Smell-first impressions from this one skew toward bright citrus peel with a layered sweetness underneath—think orange rind left in a warm room, nothing harsh or chemical. XXX OG is a 75% indica feminized strain from Amsterdam Seeds Company, testing at 22% THC and finishing flower in 8–9 weeks, which keeps it on the shorter end of the indoor calendar without sacrificing output. Growers pulling 500g/m² under good lighting aren't working miracles—that's a realistic number with dialed-in feeding and reasonable canopy management. The body effect lands heavy in the back half, so evening use makes more sense than a midday session.

It handles both indoor and outdoor environments without special fussing, though moderate grow experience helps—she responds well to topping but can get dense in the middle if airflow is ignored. Best suited for growers who want a reliable evening cultivar without chasing exotic flavor profiles.

Genetics & Lineage

XXX OG traces its genetics to 75% Indica/25% Sativa (Amsterdam Seeds Company). This indica-dominant feminized 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

XXX OG delivers THC levels of 22%, 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 XXX OG

XXX OG 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 500g/m2. Plants typically reach 100-160cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

XXX OG features a citrus, 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, XXX OG 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.

Who Should Grow XXX OG?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
