Sensi Seeds runs this as a indica feminized line — 18-25% THC lab range, citrus/earthy-dominant terps, 7-9 weeks from flip.

Lineage: Master Kush traces back to two landrace populations sourced from the Hindu Kush corridor — one Indian, one Afghan — giving it the kind of documented pedigree that's easy to verify rather than just claimed. Sensi Seeds stabilized this feminized cut to run 18–25% THC with flowering wrapping up in 7–9 weeks, which is faster than most heavy indicas at this weight class. Indoor growers pulling 400–550 g/m² should expect dense, resinous buds carrying a layered scent profile: citrus on the break, pine and damp earth underneath. The resin output is high enough that some growers set a portion aside for dry-sift or rosin work without sacrificing their main yield.

Difficulty is rated advanced — not because the plant is fragile, but because managing canopy density and airflow through those tight buds matters if you want to avoid moisture issues in humid Canadian fall conditions. Best suited to growers who've already run a couple of indica cycles and want a reliable, resin-heavy strain with a traceable genetic history.

Genetics & Lineage

Master Kush traces its genetics to Master Kush (Sensi Seeds genetics). 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 Sensi Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Master Kush delivers THC levels of 18-25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 Master Kush

Master Kush is rated as advanced difficulty, making it best suited for experienced cultivators who understand advanced techniques. This strain rewards meticulous attention to detail with exceptional results.

Indoor Growing: Expect a flowering time of 7-9 weeks with yields of 400-550g/m². Plants typically reach 60-100cm 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

Master Kush features a citrus, earthy, pine, floral 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, Master Kush 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.

This strain is ideal for advanced cultivators and breeders seeking exceptional phenotypes and willing to invest the extra care required. If you're looking for evening relaxation and deep stress relief, this is your strain.
