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.
Avoid heavy defoliation; this line uses its leaf area to power a long bloom. Target selective leaf removal for airflow without compromising photosynthesis. If foxtailing appears heat-induced, lower canopy temperatures by 1–2°C and reduce PPFD by 5–10% during midday.
Harvest Timing, Post-Harvest, and Curing
Scout trichomes beginning week 10 of flower. Most phenotypes show their best balance at mostly cloudy with 5–10% amber; harvesting at 1–3% amber skews brighter and racier, while 10–15% amber nudges toward a mellower finish. Pistils typically recede and change from bright orange to a deeper rust as calyxes swell in the final two weeks.
Dry at 16–20°C and 55–62% RH with steady airflow for 10–14 days. Avoid rapid drying that collapses monoterpene expression; losing 20–40% of terpenes is not unusual in hot, dry rooms. Once stems snap with a slight bend, trim and jar at 58–62% RH, burping daily for the first week and weekly thereafter.
Curing for 8–12 weeks notably elevates aroma complexity and smoothness, particularly in terpinolene-dominant profiles. Vacuum-sealed glass or steel containers further stabilize volatiles for long-term storage. Proper post-harvest handling can improve perceived potency and flavor intensity by a margin users often rate as 10–20% better.
Phenotype Variation, Selection, and Breeding Notes
Because The Landrace Team maintains broad genetic diversity, you should expect three broad phenotype lanes. The first finishes relatively faster at 12–13 weeks with citrus-pine and a slightly denser structure. The second runs 13–15 weeks with pronounced anise-herbal notes and elongated foxtails, while the third extends to 15–16 weeks with a highly electric effect and leaner buds.
Selecting within these lanes depends on your goals. For indoor production, many growers favor the 12–13 week lane for reliable turnaround and PPFD efficiency. Breeders seeking THCV expression can retain phenotypes with appetite-suppressing effects and sharp citrus-anise noses, then confirm via small-batch testing when possible.
When making seed, isolate males early as their internodes extend and pollen sacs form quickly under long days. Use multiple males to preserve breadth, spacing plants well to avoid competition bias. If breeding toward shorter finish and compaction, consider line-breeding across your fastest 10–20% females while monitoring that you do not lose the characteristic clarity and aroma.
Pest, Disease, and Environmental Stress Management
Mozambique Poison’s open floral structure offers a baseline advantage against botrytis, but vigilance is still necessary in humid rooms. Keep canopy RH in check and maintain strong horizontal airflow; two opposing fans per 1.2 m tent or 1 fan per 2–3 m² in rooms is a good baseline. In greenhouses, ensure roll-up sides and ridge ventilation to prevent dew deposition overnight.
Common pests include spider mites in hot, dry rooms and caterpillars outdoors during late summer. An integrated pest management plan using weekly scouting, sticky cards, and rotating soft-contact controls like oils and soaps at 0.5–1.0% can hold populations below thresholds. Introduce beneficials such as Phytoseiulus persimilis or Neoseiulus californicus early if mites are endemic to your area.
Nutrient stress often shows as over-stretch and leaf clawing from excess nitrogen. Tip burn around weeks 4–6 of flower suggests EC is too high; drop feed strength by 10–20% and increase runoff. Heat stress above 30–31°C during mid-bloom can trigger unstable foxtailing; mitigate with improved extraction or a 5–10% midday dim.
Yield Expectations and Quality Optimization
Yield is strongly linked to canopy management and flower duration. Indoors under 700–1,000 µmol·m⁻²·s⁻¹, expect 350–500 g/m² with a single-layer SCROG and 12–14 weeks of bloom, rising to 500–650 g/m² for dialed-in grows that extend slower phenotypes and optimize PPFD. Outdoors, well-grown plants in 40–60 L containers can produce 500–900 g, while in-ground plants with a full season may reach 1–2.5 kg in favorable climates.
Quality scales with slow, stable curing and careful harvest timing. Taking plants at mostly cloudy trichomes preserves the high-clarity effect many associate with African sativas. Extending an extra 7–10 days after the first maturity window often boosts yield by 5–10% but subtly shifts the effect toward calm.
Dial in root zone health for consistency. In coco and hydro, keep root temps near 20–22°C; in soil, target 18–20°C to balance oxygen and nutrient uptake. In all systems, stable VPD, moderate EC, and adequate calcium are the fastest levers for upgrading both yield and terpene intensity.
Comparisons and Context Among African Sativas
Compared with Durban-type expressions, Mozambique Poison often feels a touch drier and more herbal-citrus, with less licorice sweetness and more pine-eucalyptus lift. Malawi-type plants can be heavier and more imposing in effect; Mozambique Poison tends to deliver a cleaner, more nimble arc. Kenyan and Tanzanian landraces sometimes skew floral or lemon-lime; Mozambique commonly folds in a savory, peppered pine nuance.
These distinctions are general rather than absolute because environmental expression plays a large role. Under cooler nights and moderate EC, terpinolene lifts and pine notes sharpen. In hot rooms or after hard nutrient pushing, myrcene and earthy tones may dominate, rounding the profile and softening the effect.
For breeders and collectors, Mozambique Poison provides a complementary contrast for hybridizing with denser, later-resin hybrids. Crossing it to a compact indica-leaner can shorten flower time and add structure without erasing the sought-after clarity. Maintaining at least 25–50% of the Mozambican genome in offspring preserves the signature daytime utility.
Environmental and Geographic Rationale
Mozambique’s latitudinal spread shapes the plant’s phenology. In the north near 12–15°S, daylength stays close to 11.5–12.7 hours year-round, reducing strong seasonal photoperiod cues. In the south near 25–26°S, daylength swings a bit wider, but still less than temperate zones, favoring long, steady flowering responses.
Average coastal temperatures run 22–28°C with sea breezes that limit nighttime lows from dropping too far. Rainfall patterns concentrate from November to March, with 800–1,200 mm common along the coast and up to 1,200–1,500 mm in parts of the center-north. This climate selects for plants that resist humidity and finish despite intermittent storms.
These facts guide cultivation strategy elsewhere. Replicating a warm, bright, breezy environment with controlled humidity will elicit the intended architecture and resin profile. Using photoperiod strategies to compress finish time simply bridges the gap between near-equatorial and temperate seasons.
Practical Grow Schedules and Examples
Example indoor schedule: Veg for 3–4 weeks under 18/6 at 26°C day and 21°C night, topping once at node 4–5 and bending laterals. Flip at 20–30 cm tall into 11/13, run 55–60% RH weeks 1–4 then 50–55% weeks 5–finish, with PPFD at 800–900 µmol·m⁻²·s⁻¹. Feed 1.2–1.5 mS/cm early, rising to 1.6 mS/cm mid-bloom if needed, then taper 10–20% the final two weeks.
Example outdoor schedule at 40°N with light-dep: Transplant after last frost into 50 L containers, train and top for a low canopy. Initiate tarp on July 15 to achieve 13 hours dark, releasing on August 30 for natural finish. Harvest window lands mid-to-late September, avoiding October rains and reducing botrytis risk by more than 50% versus an unassisted November finish.
Example greenhouse schedule in humid climates: Run double-layer trellis with 1 m and 1.8 m supports, deploy horizontal airflow fans, and maintain dehumidification to keep VPD above 1.0 kPa during lights-off. Install ridge vents or active exhaust to dump heat spikes above 29°C. A 10-day late flower photoperiod reduction to 10.5 hours light can tighten the ripening window.
Buyer’s Notes and Seed Handling
As a preservation line from The Landrace Team, expect seed lots to carry broad heterogeneity, which is a feature for selection. Store seeds at 4–8°C in airtight containers with desiccant; under these conditions, viability decline is slow, often well under 5% per year over the first 3–5 years. Before sowing, a 12–18 hour soak followed by paper towel germination at 24–26°C accelerates sprouting.
Handle seedlings gently; long-coleoptile sativas can stretch if light is weak. Keep early PPFD around 250–350 µmol·m⁻²·s⁻¹ and increase gradually to 500–600 in late veg. If early sexing is needed, take a 12/12 clone at 3–4 weeks and flower it to reveal the mother’s sex.
For compliance and purity, separate Mozambique Poison from other flowering cannabis by distance and timing. Outdoor pollen can travel kilometers on wind; a practical isolation buffer of 500 m to 3 km, plus staggered flowering windows, helps preserve line integrity. Indoors, carbon filtration and dedicated rooms eliminate cross-pollination risk.
Risk Management and Troubleshooting
If plants stall in early flower, reassess root oxygen and EC. Overly wet media and EC above 1.8 mS/cm can delay bloom and cause leaf clawing. Reset by allowing more dry-back, lowering feed strength 10–20%, and ensuring robust drainage.
If aromas seem muted, inspect dry and cure conditions. Drying below 50% RH or above 22°C often strips monoterpenes; adjust to 55–62% RH and 16–20°C and extend cure to at least 6–8 weeks. If pinene and terpinolene are still faint, consider harvesting slightly earlier when trichomes are just fully cloudy.
If vertical stretch overwhelms space, deploy earlier topping and more assertive bending during days 7–21 of flower. Reducing far-red exposure at lights-off and dimming midday intensity by 10% during peak stretch can limit internode extension. As a last resort, supercrop carefully to preserve vascular flow without snapping stems.
Conclusion
Mozambique Poison, as curated by The Landrace Team, offers a faithful window into the southern African sativa experience. Its long, elegant flowering cycle produces bright, pine-citrus aromatics and a clean, energizing effect prized for daytime use. While it demands planning and patience, the line rewards careful growers with distinctive character and selection potential.
From a cultivation standpoint, success hinges on light quality, VPD stability, and photoperiod control to land a comfortable harvest window. Indoors, early training and measured feeding keep the canopy in check and resin production high. Outdoors and in greenhouses, airflow, light-dep, and trellising are the levers that convert long bloom into robust, mold-resistant yields.
For patients and enthusiasts alike, the chemotype’s likely THC dominance with possible THCV expression can deliver focus, uplift, and appetite moderation that stand apart from many modern hybrids. In a market saturated with dense, dessert-leaning cultivars, Mozambique Poison’s clarity and heritage are refreshing. It is a living archive of Mozambican agronomy and a compelling platform for both selection and enjoyment.
