The specs in one line: 17-22% THC, <1% CBD, 8-10 weeks flowering, 400-550 g/m² reported. Best indoor or outdoor. moderate grow.

Smell-first: crack a jar of cured Blackberry Kush and the room shifts — ripe berry sweetness with a thick, doughy undertone that sticks around long after the lid goes back on. That aroma carries straight into the smoke, which sits firmly on the fruity-sweet end of the spectrum without much harshness.

THC typically tests between 17–22%, so the effect leans heavily sedative — this isn't a daytime cultivar unless your afternoon is genuinely unscheduled. Yields land in the 400–550 g/m² range indoors, with an 8–10 week flowering window that fits reasonably well into a Canadian light-dep outdoor season. The feminized format cuts out the guesswork on sexing. Difficulty is moderate, meaning she rewards growers who manage humidity and airflow but won't punish small mistakes catastrophically. Best suited to growers who want a reliable, heavy-yielding indica for evening use and aren't chasing novelty — just consistent results run after run.

Genetics & Lineage

Blackberry Kush traces its genetics to Blackberry 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

Blackberry 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 Blackberry Kush

Blackberry 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

Blackberry Kush features a fruity, sweet terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Blackberry 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 Blackberry 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.
