Quick read: 24% THC, 100-160cm mature height, 8-9 weeks bloom. Genetics: Proprietary cross (Advanced Genetics). Difficulty: easy.

Smell-first: crack a cured bud of Black Russian and the citrus hits immediately—bright, almost rind-sharp, with enough depth to suggest something more complex underneath. Advanced Genetics built this feminized strain around a proprietary cross, keeping the breeding details close to the chest, but the numbers are straightforward: 24% THC, a compact 8–9 week flower period, and harvests running around 450 g/m² indoors under decent light. Plants stay manageable in height, behave well whether you're running them indoors or outdoors in a Canadian summer, and don't demand much intervention to stay healthy. The effect leans toward an active, clear-headed lift before easing into something calmer—useful if you want a daytime smoke that doesn't pin you to the couch for the afternoon.

Beginner growers who want a high-THC result without a steep learning curve will find this one of the more forgiving options in Advanced Genetics' catalogue.

Genetics & Lineage

Black Russian traces its genetics to Proprietary cross (Advanced Genetics). This hybrid-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 Advanced Genetics, 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 24%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Black Russian delivers THC levels of 24%, 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 minutes with a balanced head-and-body experience that evolves over time.

Growing Black Russian

Black Russian is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 450g/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

Black Russian features a citrus terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. 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, Black Russian 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 Black Russian?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
