Quick read: 17-22% THC, 80-150 cm mature height, 8-10 weeks bloom. Genetics: Sour Kush Feminized (Seed Supreme genetics). Difficulty: moderate.

Smell-first: crack a jar of this and diesel hits you before you even get a look at the buds — earthy undertones follow, almost like wet soil after rain. Sour Kush Feminized sits at 17–22% THC, which puts it in the mid-to-upper range without veering into the territory where newer growers lose control of the experience. Indoors, expect 400–550 g/m² after an 8–10 week flower, a reasonable window that works well with Canadian indoor schedules where light-dep seasons matter. It handles both tent and outdoor grows, though outdoor runs in shorter-season provinces like Alberta or Manitoba need a late-July flip plan to finish before the cold moves in. Difficulty is moderate — topping and basic LST will help manage the structure and push those yields toward the higher end of the range.

Best suited to growers with at least one or two runs under their belt who want a straightforward indica with a strong diesel nose and consistent finishing times.

Genetics & Lineage

Sour Kush traces its genetics to Sour Kush Feminized (Seed Supreme 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 Seed Supreme, 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Sour Kush delivers THC levels of 17-22%, 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 Sour Kush

Sour 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 8-10 weeks with yields of 400-550 g/m². Plants typically reach 80-150 cm 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

Sour Kush features a diesel, earthy 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, Sour 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.
