Durban Poison (Cannabis Strain) — Strainpedia
Durban Poison is a historic Pure Sativa landrace cultivar originating from South Africa. Widely regarded as one of the most important “Foundational Genetics” strains in modern cannabis breeding, Durban Poison represents a preserved example of classic equatorial Sativa expression. Known for its energetic cerebral profile, tall structure, and distinctive sweet-spice aroma, it has influenced countless modern hybrids and remains a benchmark reference for Sativa-dominant breeding programs.
Quick Facts
| Genetics | South African Landrace (Durban region) |
|---|---|
| Breeder | Landrace preservation; later stabilized in European breeding programs |
| Variety | Pure Sativa (landrace expression) |
| Flowering Time | 8–10 weeks (56–70 days indoors) |
| Yield Potential | 450–650 g/m² (High with proper canopy control) |
| Plant Height | 150–250 cm outdoors; vigorous vertical growth |
| Climate Preference | Warm, sunny, Mediterranean or equatorial-style climates |
| Difficulty | Intermediate (height management required indoors) |
Scientific & Botanical Overview
Durban Poison expresses classic equatorial Sativa morphology: elongated internodes, narrow leaflets, and spear-shaped colas. The plant demonstrates vigorous vertical growth during early flowering, often requiring height control in indoor environments. Its structure allows for strong airflow between flower sites, reducing moisture-related risks compared to compact Indica cultivars.
One of Durban Poison’s defining contributions to cannabis breeding is its preservation of landrace characteristics. Unlike heavily hybridized modern strains, it maintains a relatively stable Sativa chemotype and structural consistency. This made it a valuable genetic source for introducing cerebral stimulation and terpene brightness into later hybrid lines.
Effects & Use-Cases (Reported)
- Commonly reported effects: energetic uplift, heightened focus, clear-headed stimulation.
- Use-case context: daytime productivity, creative environments, physical activity.
- Functional profile: fast-onset cerebral activation with minimal heavy body sedation.
- Note: Observational reports only; not medical claims.
Aroma & Flavors
- Aroma: sweet herbal spice, earthy pine, subtle anise/licorice notes.
- Flavor: sweet citrus-spice inhale with clean herbal finish.
- Signature finish: smooth, slightly peppery sweetness with lingering freshness.
- Terpene associations: terpinolene (commonly dominant), myrcene, ocimene.
Tested Cannabinoid & Terpene Ranges
| Compound | Typical Range* | Notes |
|---|---|---|
| Δ⁹-THC | ~17–24% | Moderate-to-high potency with cerebral-forward expression. |
| CBD | <1% | Generally trace levels. |
| Terpinolene | Moderate–High | Frequently dominant; associated with bright, energetic aromatic profile. |
| Myrcene | Low–Moderate | Adds subtle earthiness and balance. |
| Ocimene | Low–Moderate | Contributes sweet herbal complexity. |
| Terpene Profile | Sweet Spice / Herbal / Pine | Classic landrace Sativa aromatic lane. |
*Ranges vary based on phenotype, cultivation conditions, harvest timing, curing, and laboratory analysis.
Cultivation Notes
- Light Cycle: 18/6 vegetative; 12/12 flowering
- Stretch: Significant during early flower; topping or ScrOG recommended indoors
- Humidity Targets: 45–55% during flowering
- Airflow: Strong airflow recommended for tall canopy management
- Harvest Window: Late September to mid-October outdoors (Northern Hemisphere)
Grower Notes (Week-by-Week Snapshot)
- Weeks 1–2: Rapid vertical growth; establish canopy structure.
- Weeks 3–4: Flower formation begins; maintain support for elongated sites.
- Weeks 5–7: Resin production increases; aroma intensifies with sweet spice notes.
- Weeks 8–10: Ripening phase; monitor trichome clarity for desired harvest timing.
- Post-Harvest: Dry at 18–20°C, 55–60% RH to preserve volatile terpinolene expression.
Genetic Lineage
Durban Poison originates from the Durban region of South Africa and is considered a preserved landrace Sativa. Later stabilized in European breeding programs, it retained much of its original equatorial expression. Its genetics have been incorporated into numerous modern hybrids, particularly those seeking cerebral stimulation and terpene brightness.
Research Insights
Durban Poison is frequently cited in discussions of terpinolene-dominant chemotypes. Its bright aromatic profile and energetic experience make it a reference model for studying terpene-driven stimulation in Sativa cultivars. As a relatively preserved landrace expression, it provides valuable insight into pre-hybrid cannabis morphology and chemotype diversity.
Why Durban Poison Is “Foundational Genetics”
Durban Poison preserved authentic landrace Sativa traits at a time when hybridization dominated breeding trends. Its structural vigor, terpene brightness, and cerebral-forward profile influenced generations of Sativa-dominant hybrids. As a globally recognized landrace reference, it remains a foundational pillar in modern cannabis genetics.
