Spec sheet first — strain: sativa, seed type: feminized, THC: 15-20%, yield band: medium, environment: indoor or outdoor.

North Atlantic Seed Company lists this at $37.80 — above the median of $31.50 across 15 listings. Pack options: 3-seed at $37.80, 5-seed at $54.00, plus larger sizes.

Lineage: straight out of South Africa, this is one of the few true landrace sativas still circulating in the US seed market — no hybrid crossing, no modern tinkering, just the original Durban genetics that put the strain on the map decades ago. Feminized seeds hit 15–20% THC with almost no CBD, and plants finish in 8–9 weeks, which is unusually quick for a pure sativa. Indoors you're looking at 400–500 g/m² when conditions are dialed in; outdoors it handles both climates with moderate attention to training, since the natural sativa structure wants to stretch.

Flavor runs earthy and sweet rather than the candy-loud profiles that dominate current catalogs — understated, but growers who've worked with it tend to come back to it for that reason. Available through NASC with US-based shipping. Best suited for growers who want a functional, clear-headed sativa without the 14-week flower wait that most landrace cuts demand.

Genetics & Lineage

Durban Poison traces its genetics to South African Sativa landrace. This sativa-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 North Atlantic Seed Company, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily energetic and creative effects, making this strain perfect for daytime use, creative projects, and staying productive. The cerebral lift arrives quickly, sharpening focus and inspiring motivation. With THC levels reaching 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Durban Poison delivers THC levels of 15-20%, 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, starting as a cerebral buzz that gradually expands.

Growing Durban Poison

Durban Poison 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 8-9 weeks with yields of 400-500 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 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

Durban Poison features a earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Durban Poison is commonly reported to help with depression, fatigue, lack of motivation, and ADHD symptoms. The uplifting, focusing effects make it popular among medical users seeking daytime functionality. 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 Durban Poison?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you need a daytime boost for creativity and sustained focus, look no further.
