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

Smell-first: the citrus hit comes through even at harvest, a clean orange-peel sharpness with a sweet finish that stays true from cure to smoke. XXX OG runs 8–9 weeks of flower and pulls around 500 g/m² under proper light, which makes it a reasonable target for indoor setups or a sheltered outdoor run in Canadian zones where the season cuts short. At 22% THC, the effect leans heavily on the indica side — 75% of the lineage — so expect a heavy body response in the back half of the session rather than a social, functional high.

Plants stay manageable in height and respond well to basic training like LST or a single topping. Difficulty sits at moderate, meaning you should have at least one grow under your belt before committing a full tent to it. Best suited to indoor growers chasing a heavy evening strain with consistent resin production and a straightforward citrus flavor profile.

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.
