Mozambique Poison is a sativa-heritage landrace line curated and distributed by The Landrace Team, a breeder known for preserving regionally adapted cannabis populations. As its name suggests, the line traces to traditional cannabis grown across Mozambique, a southeastern African nation with a tropical to subtropical climate. The term Poison nods to the famous southern African sativa archetype while distinguishing this Mozambican expression from the South African Durban lineage.
Expect an energetic, narrow-leaf tropical profile that reflects long adaptation to short, near-equatorial photoperiods. Flowering is typically long compared with modern hybrids, but the payoffs include complex, high-clarity effects and a bright, terpinolene-forward bouquet. Growers who plan correctly can achieve competitive yields while preserving the characteristic open, foxtailed architecture of African landrace sativas.
Because Mozambique spans latitudes roughly 11°S to 26°S, daylength varies modestly compared with temperate zones, shaping how local cannabis initiates and completes flowering. This background explains why Mozambique Poison responds well to 11–12 hours of light in flower and may require additional photoperiod manipulation to finish at higher latitudes. The Landrace Team’s open-pollination and preservation strategy means phenotypic diversity is an asset, not a flaw, inviting growers to select plants suited to their environment and goals.
Historical Context in Mozambique
Cannabis has a deep history in Mozambique, intertwined with Indian Ocean trade routes and regional agricultural traditions. Historical accounts suggest introduction via maritime networks linking East Africa, the Arabian Peninsula, and South Asia centuries ago. Over time, local farmers selected for resin, vigor, and adaptation to coastal and riverine microclimates, producing distinct narrow-leaf sativa expressions.
In the colonial era, cannabis persisted as a rural cash crop and cultural plant despite periodic suppression. After independence, cultivation continued in dispersed smallholder systems, especially along fertile zones near the Zambezi and Limpopo rivers. These low-input, field-grown practices exerted selection pressure for mold resistance, heat tolerance, and long-flowering resilience.
Mozambique’s climate helps explain the sensory and structural traits observed in this line. Coastal regions see annual rainfall commonly in the 800–1,200 mm range, while central-northern provinces can exceed 1,200 mm, with warm average temperatures of 22–28°C across much of the year. Such conditions favor open, airy blossoms that shed humidity and a terpene profile that leans herbal-citrus and pine, traits prized by traditional consumers.
Genetic Lineage and Breeding Background
Mozambique Poison is best understood as a regionally adapted landrace sativa rather than a modern polyhybrid. The Landrace Team sourced it from Mozambican farmer selections and maintained it via broad, open-pollination to preserve genetic breadth. This differs from highly inbred, stabilized commercial cultivars; expect noticeable phenotypic variation within seed packs.
That variation is not random, but clusters around a coherent tropical sativa archetype. You are likely to see narrow leaflets, long internodes, and a high calyx-to-leaf ratio relative to leaf mass. Some phenotypes will be faster-finishing and citrus-forward, while others run longer with anise, pine, and herbal notes, reflecting long-standing local selection drivers.
Genetically, African sativas are often associated with elevated terpinolene and ocimene fractions in the terpene spectrum and, in some plants, measurable THCV. While not all Mozambican lines are THCV-rich, a subset commonly expresses THCV in the 0.3–1.2% range by dry weight when total THC is in the mid-teens. The Landrace Team’s approach intentionally keeps this diversity intact so growers and breeders can select for target traits over successive generations.
Morphology and Appearance
Plants typically exhibit narrow-leaf, tropical morphology with elongated, flexible limbs that can easily exceed 150–220 cm indoors if not trained. Internode spacing of 5–10 cm is common under high light, stretching to 10–15 cm if light intensity is low or nitrogen is excessive. Outdoors in warm climates, well-rooted plants can reach 300–500 cm by late season, developing an elegant, whorled canopy that maximizes airflow.
Inflorescences are airy to medium-dense with distinctive foxtails, optimizing humidity shedding and reducing botrytis risk. Calyxes stack in tapering spears, and pistils swing from white to orange-rust as maturation advances. The calyx-to-leaf ratio often trends high for a landrace, speeding up trim time compared with broader-leaf equatorial lines.
Trichomes are abundant though not always as bulky as those on modern resin-bred hybrids. Under magnification, capitate-stalked heads cover bracts in a silver frost that can look lighter and more champagne-colored than the opaque white of dense indica-leaning buds. Stems are surprisingly strong for their slender appearance, especially when supplemented with silica at 50–100 ppm throughout veg and early flower.
Aroma and Flavor
Expect a terpinolene-driven nose that blends green mango, sweet citrus zest, and fresh pine. Secondary layers commonly include beta-ocimene’s sweet-herbal tones, with accents of anise, black pepper, and eucalyptus. On the plant, rubbing a bract often releases a peppered lime top note followed by a dry, woody finish.
In a clean cure, the flavor sharpens to citrus-herbal with crisp pine and faint floral sweetness on the exhale. Some phenotypes lean more toward lemongrass and guava, while others push into aniseed and resinous wood. The aftertaste is typically dry and refreshing rather than syrupy, which many users describe as clean and focused.
Volatile expression depends on cure parameters. Slow drying at 16–20°C and 55–62% relative humidity for 10–14 days preserves monoterpenes, while an 8–12 week jar cure rounds off edges without muting brightness. Over-drying below 50% RH or curing hot above 22°C tends to flatten the higher notes and favor earthy-musk tones.
Cannabinoid Profile
Reported lab assays for comparable southern African sativa landraces show THC commonly in the 12–20% range by dry weight, with outliers as high as 22% under ideal cultivation. Mozambique Poison typically falls within this window when grown under high light, with meticulous post-harvest handling boosting realized potency by 1–2 percentage points. CBD is usually minimal at 0.05–0.8%, placing the line in a THC-dominant category.
A notable feature in some African lines is THCV expression. In Mozambique Poison, expect a subset expressing THCV around 0.3–1.2%, especially in phenotypes that show pronounced citrus-pine and a slightly more racy effect. CBG content is generally low to moderate, often in the 0.2–0.8% range, though late harvests can push CBG marginally higher.
Grower practices strongly influence final numbers. Light intensity above 700–900 µmol·m⁻²·s⁻¹, stable VPD, and careful drying can preserve 5–15% more cannabinoids compared with stressed, fluctuating environments. Conversely, nutrient burn or overwatering during weeks 3–6 of flower can depress THC by several percentage points due to impaired resin biosynthesis.
Terpene Profile
Total terpene content typically ranges from 0.8–2.2% by dry weight (8–22 mg/g), depending on environment and cure. A common chemotype is terpinolene-dominant, with terpinolene comprising 25–40% of the terpene fraction. Beta-ocimene frequently follows at 10–18%, while myrcene often lands around 10–20%, especially in fruitier phenotypes.
Supporting terpenes usually include beta-caryophyllene at 5–12%, alpha-pinene at 3–8%, and humulene at 2–6%. Limonene often contributes 2–6% for citrus lift, with linalool at 1–3% adding subtle floral undertones. Trace contributors like fenchol, nerolidol, and terpineol may appear and influence the perceived dryness or sweetness of the finish.
This distribution aligns with the classic southern African sativa aroma spectrum that emphasizes fresh, bright volatiles over heavy, dank sesquiterpenes. Terpene retention is highly sensitive to post-harvest handling; prolonged drying beyond 14 days at low humidity can cut monoterpenes by 20–40%. A well-managed cure can stabilize the profile so that the bouquet remains vivid for months.
Experiential Effects and Potency
Mozambique Poison is widely described as clear-headed, energizing, and creatively stimulating. The onset is quick, often within 2–5 minutes when smoked and 10–20 minutes when vaporized. Peak effects typically last 60–120 minutes, with a taper that can extend another hour depending on dose and tolerance.
Users commonly report enhanced focus, uplifted mood, and a sense of mental brightness rather than heavy euphoria. Physical energy often increases slightly without the jitteriness some modern terpinolene bombs can provoke. Phenotypes with higher THCV percentages may feel a bit sharper and shorter in duration, while more myrcene-forward plants can soften the edges and prolong the arc.
As with many potent sativas, sensitive individuals may experience momentary anxiety at high doses, especially in stimulating environments. Starting with small inhalations or a 2.5–5 mg THC equivalent helps gauge response. Hydration and steady breathing can moderate racy moments, and most users acclimate after a few sessions.
Potential Medical Uses
While formal clinical trials on Mozambique-specific landraces are limited, the chemotype suggests several plausible applications. The uplifting, focus-enhancing profile may aid daytime fatigue and low motivation associated with mild depressive states. Anecdotal reports often cite improved task initiation and reduced perceived effort during cognitively demanding work.
Anti-inflammatory potential stems from beta-caryophyllene’s CB2 agonism, which has been linked to modulation of inflammatory pathways in preclinical models. Limonene and pinene contribute bronchodilatory and alertness-supporting effects, which some users find helpful for minor airway tightness or brain fog. THCV has been studied preliminarily for appetite regulation and glycemic control, aligning with user reports of reduced munchies compared with typical THC-dominant strains.
For pain, expect better performance on neuropathic or tension-related discomfort than on deep, nociceptive pain where heavier indica chemovars often excel. Migraineurs sometimes report early-phase relief, likely due to distraction and vasomodulatory effects, though outcomes vary. As always, medical use should be guided by personal response, low starting doses, and consultation with a clinician where possible.
Cultivation Guide: Planning and Setup
Mozambique Poison thrives when growers plan for vertical space, extended flowering, and high light quality. Indoors, target 700–1,000 µmol·m⁻²·s⁻¹ PPFD in flower with full-spectrum LED or high-quality HPS/CMH, ensuring even distribution to limit foxtail heat stress. Outdoors, choose a site with 8+ hours of direct sun and strong airflow; coastal breezes are ideal.
Because this is a preservation line from The Landrace Team, anticipate phenotype variability and plan to run 6–12 plants if selection is a goal. This sample size increases the odds of capturing faster-finishing or terpene-rich individuals. Keep clones of promising plants early; many landrace sativas show late-bloom excellence that you will want to preserve.
Set expectations for flowering duration of 12–16 weeks after the flip, depending on phenotype and photoperiod strategy. In higher latitudes, consider initiating flower at 11/13 or 10.5/13.5 to avoid December finishes, or use light-deprivation outdoors to hit an earlier harvest window. If time is tight, select faster plants by week 5–6 of flower for scaling up.
Cultivation Guide: Indoor Protocols
Germination rates with fresh, well-stored seed are typically 85–95% within 48–96 hours using a 24–26°C root zone and lightly oxygenated media. Start seedlings in small containers, then up-pot incrementally to control root speed and minimize stretch; a 0.25 L to 1 L to 4 L progression works well before final containers. Maintain veg temperatures at 24–28°C day and 20–22°C night with a VPD of 0.8–1.2 kPa.
During veg, Mozambique Poison responds well to low-stress training and early topping to break apical dominance. Aim for a flat canopy to control vertical growth; SCROG nets are effective for distributing sites. Flip earlier than you would with compact hybrids; a 20–30 cm pre-flip height often finishes near 80–120 cm depending on phenotype and training.
In flower, run day temperatures of 25–29°C and nights of 19–21°C with a VPD of 1.0–1.4 kPa to maximize resin production. Keep RH at 55–62% through week 4, then 50–58% afterward; lower is acceptable if airflow is excellent. Many growers find that an 11/13 schedule from day one of flower shortens total duration by 7–14 days without sacrificing yield.
Cultivation Guide: Outdoor and Greenhouse Protocols
Outdoors, Mozambique Poison favors warm, well-drained soils with moderate fertility. A sandy loam with 10–20% compost and good calcium levels supports sturdy stems and terpene expression. Ideal planting densities in the ground are 1.2–2.0 meters between plants, widening spacing in humid climates for airflow.
In the southern hemisphere, expect harvest from late April to June depending on latitude and photoperiod management, with faster phenotypes finishing earlier. In the northern hemisphere, unassisted finishes can push into November or early December above 35°N, making greenhouses with light-dep highly recommended. A 10–14 day light-dep during mid-summer can time harvests for drier fall windows, cutting mold risk dramatically.
Greenhouses allow tighter VPD control and shelter from heavy rainfall, which averages 800–1,200 mm annually along much of the Mozambican coast. Use horizontal airflow fans and roll-up sides to maintain leaf-surface evaporation. For tall phenotypes, trellis in two to three layers to stabilize spears against wind and to preserve internode integrity.
Feeding, Irrigation, and Environmental Parameters
Landrace sativas often prefer lighter feeding than modern hybrids. Start veg at 0.8–1.2 mS/cm (EC) and step up to 1.2–1.6 mS/cm in early flower, peaking around 1.6–1.8 mS/cm only if leaf color remains light and growth demands it. Excess nitrogen late in veg and early flower is a common cause of over-stretch and delayed ripening.
Maintain media pH at 6.2–6.8 in soil and 5.7–6.1 in hydro or coco. Provide calcium and magnesium consistently, especially under high-intensity LED, at 100–150 ppm Ca and 40–60 ppm Mg. Silica at 50–100 ppm strengthens stems and may reduce mite pressure by toughening leaf surfaces.
Irrigate to 10–20% runoff in container systems, allowing media to approach, but not reach, full dryness between events. In coco, a 2–4 times per day pulse-fed strategy in small doses keeps EC stable and promotes steady growth. Outdoors, drip systems delivering 1.5–3.0 liters per plant per day in early veg, rising to 5–8 liters in peak flower for 40–60 L containers, are typical in warm climates.
Training, Photoperiod, and Flowering Management
Topping once or twice in early veg produces multiple colas without excessively increasing total count. Combine topping with lateral bending and a single-layer SCROG to flatten the canopy. Mozambique Poison responds well to apical softening techniques that reduce vertical dominance while preserving natural spear formation.
Photoperiod control is a major lever for finishing time. Indoors, starting flower at 11/13 and later reducing to 10.5/13.5 after week 8 can cue ripening in slower phenotypes. Outdoors, a simple tarping schedule of 13 hours dark can move finish dates forward by 2–4 weeks.
