Why this one matters: hybrid genetics with a 20-25% THC ceiling and fruity/diesel-led terps. 9-11 weeks flowering, indoor or outdoor.

Kannabia Seeds lists this at $23.87 — the lowest base price in the comparison ($25.98 floor). Pack options: 3-seed at $23.87, 5-seed at $37.04, plus larger sizes.

Smell-first: crack a cured bud and you get fruit punch cut with raw diesel, then a clean sweetness that lingers on the exhale. That flavor profile is the calling card of GSC from Kannabia Seeds, a feminized strain that tests consistently between 20–25% THC without leaning too hard in any one direction—you get a creative, euphoric opening that eventually settles into something more sedating.

Flowering runs 9–11 weeks and indoor growers regularly pull 400–500 g/m², which is a respectable number for a strain that doesn't demand expert-level dialing in. Kannabia rates it moderate difficulty, so it's forgiving enough for growers past their first run but rewards anyone willing to manage canopy and dial in the cure. Both indoor and outdoor environments work. Best suited for growers who want a crowd-pleasing, high-THC smoke with a complex nose and don't want to babysit every feed schedule to get there.

Genetics & Lineage

GSC traces its genetics to GSC (Kannabia Seeds). 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 Kannabia 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

GSC 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 minutes with a balanced head-and-body experience that evolves over time.

Growing GSC

GSC 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 9-11 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 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

GSC features a fruity, diesel, sweet, earthy 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, GSC 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 GSC?

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.
