Spec sheet first — strain: indica, seed type: feminized, THC: 20-25%, yield band: medium, environment: indoor or outdoor.

Smell-first, this one announces itself before the jar is even open — that sharp diesel-skunk cut that old-school indica fans recognize immediately, followed by a quieter citrus note on the back end. Rooted in Hindu Kush and Skunk lineage, Master Kush Feminized from Nirvana Seeds sits at 20–25% THC with virtually no CBD, so the effect leans heavily sedative. Flowering wraps up in 7–9 weeks, and indoor growers running it under decent light routinely pull 400–500 g/m² without much drama.

Moderate difficulty means it rewards growers who know the basics — consistent temps, proper airflow — but it won't punish minor mistakes the way some high-THC indicas do. The compact structure handles both tent and outdoor setups across Canadian climates, finishing before most regions see first frost. Best suited to evening growers who want a reliable, hard-hitting indica without hunting down boutique genetics.

Genetics & Lineage

Master Kush traces its genetics to Master Kush Feminized (Nirvana Seeds). 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 Nirvana Seeds, 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Master Kush delivers THC levels of 20-25%, 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 Master Kush

Master Kush 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 7-9 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm 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, diesel, skunky, sweet terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. 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.

Who Should Grow Master Kush?

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.
