Tashkurgan is an indica-heritage cannabis variety curated and released by Landrace Bureau, a breeder known for sourcing and stewarding traditional seedlines. The name references Tashkurgan, a high-altitude region at the western edge of China where Central Asian trade routes converge. In cannabis circles, the label signals a broadleaf, hash-leaning landrace expression adapted to cool nights, strong sun, and short seasons.
Growers prize Tashkurgan for its sturdy architecture, dense resin production, and relatively early finish. Enthusiasts describe it as a calming, body-forward cultivar with grounding aromatics reminiscent of classic hashish. When grown and cured correctly, it produces a layered sensory experience alongside consistent, manageable potency.
As an indica line stewarded by Landrace Bureau, Tashkurgan offers both cultural heritage and agronomic predictability. It can be run indoors in 7–9 weeks of bloom, and outdoors it finishes before prolonged autumn moisture in many temperate zones. With proper environmental control, total terpene content can reach 1.5–2.5% of dry mass, contributing to its signature incense-and-earth bouquet.
History
Tashkurgan’s identity is tied to the trans-Pamir crossroads where Tajik, Wakhi, Kyrgyz, and other highland peoples have exchanged goods for centuries. Traditional cannabis cultivation in the greater Pamir and Karakoram sphere has long emphasized resin for sieved and hand-rolled preparations rather than airy, smoke-only flowers. The combination of altitude, intense UV exposure, and short frost-free windows favored broadleaf plants that finish quickly and produce large, easily separable trichome heads.
Landrace Bureau introduced Tashkurgan as a seedline representing those high-country indica traits. Rather than blending modern hybrids, their approach typically emphasizes seed collecting, increasing, and selective curation to stabilize field-worthy expressions. The aim is to retain the original regional character while improving germination uniformity and garden performance.
Reports from cultivators in Europe and North America began circulating around the late 2010s and early 2020s as the line became more widely available. Early adopters highlighted cool-night tolerance and resin density reminiscent of Afghan and Gilgit-Baltistan types, yet with distinctive flavor nuances. Over successive increases, selection has tightened internodal uniformity and reduced outlier phenotypes that flower too slowly for mid-latitude gardens.
Today, Tashkurgan occupies a niche among landrace-informed indica collectors and hashmakers. It is often positioned alongside Afghan, Chitral, and Pamiri accessions, with some growers preferring its slightly brighter spice-wood aroma. While still showing healthy diversity typical of landrace-derived populations, the line has matured into a reliable choice for short-season, resin-focused cultivation.
Genetic Lineage
Tashkurgan’s genetic identity is best described as an indica landrace accession curated for seed accuracy rather than a modern hybrid cross. It likely descends from Central Asian broadleaf populations shaped by generations of selection for resin yield and early ripening. These populations evolved under high UV-B and low humidity, conditions that select for dense trichome coverage and thick cuticles.
Within the indica spectrum, Tashkurgan leans toward the so-called hashplant architecture: squat to medium height, strong lateral branching, and heavy terminal colas. Internodes tend to be short, with a significant proportion of calyx mass relative to leaf in late bloom. Although the population maintains variability, a majority of plants cluster around this compact, resin-first phenotype.
From a chemotypic perspective, Tashkurgan aligns with THC-dominant Type I cannabis, with low baseline CBD expression. Minor cannabinoids such as CBG often appear in the 0.2–1.0% range by dry weight in dialed-in gardens, a pattern consistent with many Central Asian lines. THCV is typically trace-level but can occasionally peak near 0.3% in outlier plants.
Because Landrace Bureau’s intent is preservation and responsible curation, the line is presented as a regional representation rather than a single inbred genotype. Growers should expect a coherent family of indica expressions rather than clones-in-seed. Selection over two to three runs can refine a keeper mother that captures the line’s resin traits and finishing times.
Appearance
In vegetative growth, Tashkurgan shows broad leaflets, sturdy petioles, and a dark green hue that edges toward blue-green under cooler nights. Average indoor height at flip ranges from 40–70 cm, finishing between 80–120 cm depending on training and pot size. Outdoor plants typically reach 120–180 cm in short-season climates, with a stout, hedge-like profile.
By week five of bloom, flowers stack densely with heavy calyx formation and minimal foxtailing under proper heat management. Pistils begin cream-colored, shifting to orange-brown as trichomes mature. Mature buds are glistening and weighty, with sugar leaves sparsely distributed compared to calyx mass.
Trichome heads are prominent and uniform, a trait hashmakers note for clean separations. Resin coverage often extends well onto the small fan leaves, increasing dry sift returns. After cure, flowers maintain compact density and break apart with a resinous tack that darkens on the fingers.
Aroma
The dominant aromatic impression is hashy and incense-like, underpinned by loam and seasoned wood. Many growers note a sandalwood-cedar core accented by black tea and dried herb. There is often a subtle sweet edge reminiscent of dried date or apricot, especially after a 4–6 week cure.
Terpene synergy lends a peppered warmth with caryophyllene and humulene providing the spice-wood scaffold. Myrcene contributes the rounded earth and herb note, while a touch of pinene keeps the nose from flattening. Occasional phenotypes lean toward leather and cured tobacco, particularly when dried at lower temperatures.
The intensity scales up with proper environmental control during late flower. When target RH is held around 42–48% and canopy temperatures stay near 22–24°C, total volatiles tend to preserve better. Post-cure jar burps reveal a layered bouquet with incense, earth, and tea oscillating as the jars outgas.
Flavor
On inhalation, expect immediate hash resin and spiced wood, followed by a smooth, tea-like dryness. The mid-palate frequently adds subtle pine-citrus from pinene-limonene synergy, balancing the deeper earth tones. Exhale trails into sandalwood and black pepper, leaving a faint sweet-dried-fruit echo.
Combustion quality is generally smooth when plants are properly flushed and dried at a slow, cool pace. Keeping drying conditions around 16–18°C and 58–62% RH for 10–14 days helps retain the incense note while preventing chlorophyll bite. A 4–8 week cure rounds the pepper edges and deepens the tea-wood profile.
Vapers will notice a cleaner distinction between layers, often tasting cedar and tea in the first few pulls before the resin core blooms. Terpene volatilization is highest early in a session, so lower-temperature draws preserve the finer dried-fruit nuance. As the session progresses, the flavor consolidates around hash and wood.
Cannabinoid Profile
Tashkurgan typically expresses as a THC-dominant Type I chemotype. Indoor runs with strong light and balanced nutrition often test in the 17–22% THC range by dry weight. Outdoor sun-grown at higher latitudes commonly lands between 14–20% THC, reflecting broader environmental variability.
CBD in this line is generally low, often below 0.5% and commonly under 0.2%, maintaining a high THC:CBD ratio. Minor cannabinoids that appear with some regularity include CBG at 0.2–1.0% and CBC in the 0.1–0.4% band. THCV is typically trace-level, though occasional phenotypes can reach around 0.2–0.3%.
For practical dosing, a 0.3 g inhaled portion from a 20% THC flower contains about 60 mg of total THC potential before combustion losses. Accounting for delivery efficiency and pyrolytic loss, users may experience 25–40 mg absorbed, depending on device and technique. Edible infusions from this line decarboxylate efficiently, with THCA-to-THC conversion yields commonly around 85–90% under controlled 110–120°C processes.
Total cannabinoid content often correlates with canopy health and light density. Targeting 700–1000 µmol·m⁻²·s⁻¹ PPFD in flower and maintaining balanced EC typically pushes THC expression toward the upper end of the range. Conversely, excessive heat stress or nutrient imbalance can shift outcomes downward by several percentage points.
Terpene Profile
Tashkurgan’s terpene fingerprint is anchored by beta-myrcene, beta-caryophyllene, and alpha-humulene. In dialed-in indoor grows, total terpene content often reaches 1.5–2.5% of dry mass, while outdoor figures commonly sit between 1.0–2.0%. Myrcene frequently occupies the 0.4–0.9% range, giving the cultivar its earthy-herbal core.
Beta-caryophyllene typically expresses around 0.2–0.6%, contributing pepper-spice warmth and potential CB2 receptor interactions. Alpha-humulene is often present at 0.1–0.3%, reinforcing the woody, slightly bitter-sap nuance. Secondary contributors like alpha-pinene (0.1–0.25%) and limonene (0.1–0.2%) brighten the profile without shifting it to citrus-forward territory.
Linalool appears variably, commonly 0.05–0.15%, which can inflect the bouquet with a faint floral-lavender softness in select phenotypes. Terpinolene is generally minimal or absent, differentiating Tashkurgan from some Asian narrow-leaf lines that skew terpinolene-dominant. When environmental stress is minimized, the relative balance of caryophyllene and humulene tends to tighten, producing a more consistent incense-wood signature.
Terpene preservation hinges on careful handling from late flower onward. Keeping late-flower canopy temps near 22–24°C and RH at 40–50% minimizes volatilization and oxidative loss. During drying, a 10–14 day slow curve at 16–18°C and 58–62% RH can retain 70% or more of terpenes compared to a rapid dry.
Experiential Effects
The onset is clean and body-forward, with relaxation moving from the shoulders and upper back downward. Users often report a steadying mental quiet rather than a racy headspace, aligning with its indica heritage. Within 10–15 minutes, muscle tension tends to soften, and a calm, anchored mood settles in.
At moderate doses, the mental state remains clear enough for low-effort tasks, conversation, and wind-down routines. Higher doses push toward couchlock and nodding, especially when 10–25% of trichomes are amber at harvest. Appetite stimulation is common, and time perception may slow subtly during the peak.
Duration typically stretches 2–3 hours for inhalation routes, with a gentle taper and minimal residual grogginess if harvested at mostly cloudy trichomes. Edible preparations extend the effect window to 4–6 hours or more depending on dose. Side effects are usually limited to dry mouth and dry eyes, though sensitive users may experience dizziness on rapid standing.
Phenotypic variation influences tone: myrcene-heavier expressions skew sedative, while brighter pinene-limonene phenos feel marginally more alert. Harvest timing also matters; earlier harvests (mostly cloudy) skew relaxing without heavy sedation, whereas later harvests (20–30% amber) increase weight and sleepiness. Individual set and setting remain strong modulators of the experience.
Potential Medical Uses
With a THC-dominant profile and myrcene-caryophyllene-humulene terpene matrix, Tashkurgan aligns with use-cases involving tension, discomfort, and sleep. The body-centered relaxation and muscle unwinding reported by many users make it a candidate for evening pain management. Appetite stimulation may benefit those experiencing decreased intake due to stress or medication side effects.
Evidence from the National Academies (2017) concluded substantial support for cannabinoids in chronic pain and chemotherapy-induced nausea, though strain-specific trials remain limited. Tashkurgan’s caryophyllene content, which can engage CB2 receptors, is of interest for inflammatory pathways, albeit clinical data are still emerging. Observational surveys often find that indica-leaning, myrcene-forward cultivars correlate with improved sleep onset, particularly in populations with baseline insomnia symptoms.
Patients sensitive to anxiety spikes from limonene-forward sativa types sometimes prefer Tashkurgan’s steadier tone. However, the THC-dominant nature means dose titration is essential to avoid dysphoria or dizziness. For daytime use in pain contexts, microdoses and earlier harvest chemotypes may help reduce sedation while preserving analgesic value.
As with any medical application, individual response varies with physiology, tolerance, and concurrent medications. Vaporized flower allows for fine-grained dose control in the 2–5 mg THC increments that many patients find manageable. Always consult a clinician in jurisdictions where medical guidance is available, especially when combining cannabis with sedatives or blood pressure medications.
Comprehensive Cultivation Guide
Growth habit and timing: Tashkurgan is a compact to medium-height indica with a natural predilection for dense colas. Indoors it typically completes in 49–63 days of flowering (7–9 weeks), with many keeper phenotypes finishing around day 56–60. Outdoors at 35–45°N, expect harvest from late September to mid-October depending on microclimate and phenotype.
Height management is straightforward: topping once at the 4th–6th node and applying low-stress training produces a broad, even canopy. Internodes are short, so overlong veg can create overly dense canopies prone to microclimate moisture. Keep veg times to 3–5 weeks for most indoor setups unless using SCROG.
Environment and VPD: In veg, target 24–28°C daytime, 18–22°C nighttime, and 55–65% RH for vigorous growth. In bloom, run 22–26°C days, 16–20°C nights, and 40–50% RH; drop to 35–45% RH in late flower to protect against botrytis. Maintain VPD near 0.8–1.2 kPa in veg and 1.2–1.6 kPa in flower.
Lighting and DLI: Seedlings prefer 200–400 µmol·m⁻²·s⁻¹ PPFD; veg targets 400–700; flower 700–1000, with CO2 supplementation above 850 µmol advisable. Daily light integrals of 35–45 mol·m⁻²·day⁻¹ in veg and 45–55 in flower are effective benchmarks. Watch for light burn on resin-heavy tops when PPFD exceeds 1000 µmol without CO2; reduce intensity or raise fixtures.
Media and pH: In soil, aim for pH 6.2–6.8; in coco/hydro, 5.8–6.2. Well-aerated mixes with 20–30% perlite or pumice help prevent waterlogging under the plant’s dense structure. In high-frequency fertigation (coco), 1–5 irrigations per day in late flower maintains stable EC and oxygenation.
Nutrition and EC: Tashkurgan is a moderate-to-heavy feeder that responds well to a classic 3-1-2 NPK profile in late veg. In early flower, transition to roughly 1-2-2, and finish with 0-3-3 leaning formulas as nitrogen is tapered. In coco/hydro, keep solution EC around 1.6–2.2 mS·cm⁻¹ in mid-flower, peaking near 2.4 if plants signal demand; in soil, monitor runoff to avoid salt accumulation.
Calcium and magnesium are critical to prevent tip burn under high light; target 150–200 ppm Ca and 50–70 ppm Mg in solution. Silica supplementation (50–100 ppm monosilicic acid equivalent) can improve stem rigidity and stress tolerance. Excessive nitrogen late in bloom reduces aroma intensity and prolongs maturation, so taper N by week five.
Irrigation strategy: Allow 10–20% runoff in coco to maintain EC stability; in soil, water to healthy runoff as needed but avoid saturation that lingers beyond 24 hours. Late flower consumption can reach 3–6 liters per 10-liter pot per day depending on conditions. Use moisture sensors or pot weight to standardize routines across tables.
Training and canopy: Topping plus LST produces 6–12 main sites on a 30–50 cm spread per plant, which fits well under 60 × 60 cm footprints. SCROG nets at 15 cm squares help support heavy colas and maintain airflow. Sea of Green is also viable: run 16–25 plants per m² from short veg or rooted clones, flipping at 15–25 cm tall for uniform single-cola production.
Plant density and yields: In SCROG, expect 500–650 g·m⁻² with optimized environments and 800–1000 µmol PPFD. In SOG, yields commonly fall in the 400–550 g·m⁻² band with fast turnover. Outdoor plants in 50–100 liter containers can produce 400–900 g per plant with adequate sun (≥6–8 hours direct) and wind management.
Pest and disease management: Due to dense buds, botrytis is the primary threat in humid regions. Keep late-flower RH below 50%, run strong oscillating airflow, and defoliate modestly around day 21 and day 42 to open the interior. Integrate weekly scouting for spider mites and thrips; prophylactic biologicals like Bacillus subtilis (for molds) and Beauveria bassiana (for soft-bodied insects) can reduce outbreaks.
Regional adaptation: Tashkurgan’s highland ancestry conveys good tolerance to cool nights and large diurnal swings. It maintains metabolism with night temps down to 12–14°C without major terpene loss, though growth slows if nights persist under 10°C. In hot climates, manage canopy temps and consider midday shading to keep leaf surface below 28–29°C.
Photoperiod and outdoors: The critical photoperiod is close to 14–14.5 hours; flowering initiates reliably as days shorten after solstice. For 40–45°N latitudes, pre-veg indoors by 2–4 weeks and transplant after the last frost to maximize vegetative bulk. Use staking or cages before mid-August to support the developing colas against wind.
Harvest timing: For a balanced relaxant effect, harvest when trichomes are roughly 5–15% amber and the rest cloudy. For more sedation, push to 20–30% amber, but monitor for oxidative aroma loss. Typical window is day 56–63 indoors; outdoor windows narrow with weather, so prioritize plant health over chasing maximal amber.
Drying and curing: Aim for 10–14 days at 16–18°C and 58–62% RH with gentle air exchange and minimal direct airflow on flowers. Once stems snap, jar at 62% RH and burp daily for the first week, then weekly for 4–8 weeks. Properly cured flower stabilizes at 10–12% moisture content with water activity around 0.55–0.65, preserving 60–80% of aromatic volatiles versus fast drying.
Seed handling and germination: Landrace-derived populations often show robust seed vigor; many growers report 85–95% germination under optimal methods. Soak seeds 12–18 hours at 20–24°C, plant 1–2 cm deep in pre-moistened media, and maintain 24–26°C root zone warmth. Expect radicle emergence within 24–72 hours and cotyledon lift shortly after.
Cloning and mother care: Tashkurgan clones readily when cuttings are taken from non-lignified tissue and rooted under 22–24°C and 70–85% RH. Rooting hormones at 0.3–0.6% IBA work well; roots typically form in 7–12 days. Maintain mothers under moderate light (PPFD 300–500) and prune regularly to prevent woody growth that slows rooting.
Hashmaking and resin: The cultivar’s resin heads are well-suited to mechanical separation. Dry sift yields of 10–18% and ice water extraction yields of 12–20% are achievable on well-grown material, with top grades showing high melt. Cold rooms (≤10°C) and gentle agitation maximize head retention and reduce contaminant load.
Common mistakes: Overly long veg times create humidity traps and botrytis risk. Excess nitrogen beyond week five softens aroma and delays ripening. Aggressive defoliation in late flower can stress plants and reduce resin density; favor targeted leaf tucking and selective removals.
Data-driven checkpoints: Track EC and pH daily in coco/hydro, and weekly runoff checks in soil to keep drift within ±0.2 pH units and ±0.3 mS·cm⁻¹. Keep canopy PPFD mapping within ±10–15% uniformity to prevent uneven ripening. Log VPD and leaf temperature; maintaining leaf-level 22–24°C in late flower correlates strongly with terpene retention in this line.
Breeding and selection notes: Expect a coherent indica family with measurable phenotypic spread; select keepers over two cycles to confirm stability. Favor plants that finish by day 56–60 with tight internodes, high calyx-to-leaf ratios, and strong caryophyllene-humulene expression. Avoid outliers that run beyond day 65 unless their resin quality and uniqueness justify longer cycles.
Compliance and odor control: The incense-wood aroma is potent in late flower and during drying. Activated carbon filtration at 0.1–0.2 m³·s⁻¹ per m² canopy, sealed rooms, and negative pressure maintain odor discipline. For outdoor grows in odor-sensitive areas, plant windbreaks and time harvests to avoid hot, still afternoons when scent plumes intensify.
Summary performance: Well-managed indoor grows routinely achieve 1.5–2.0 grams per watt under white LEDs at 700–900 µmol PPFD, with total terpene content around 1.5–2.5% by dry weight. Outdoor grows in sunny, dry climates produce dense, resin-rich flowers that wash efficiently. Tashkurgan’s indica heritage from Landrace Bureau delivers reliable finish times, stout frames, and a classic hash-forward profile that rewards attentive stewardship.
