Iraqi 66 is a mostly indica cultivar bred and popularized by Bodhi Seeds, a breeder renowned for curating heirloom and landrace genetics from Asia and the Middle East. Growers gravitate to Iraqi 66 for its dense, resin-heavy flowers, tranquil body-led effects, and robust performance in warm, dry conditions. While not as ubiquitous in retail dispensaries as modern dessert-forward hybrids, the strain has a loyal following among home cultivators, hashmakers, and connoisseurs seeking old-world resin character.
Because Iraqi 66 originates from a region with a long tradition of hashish production, it often exhibits traits associated with classic hash plants: stout structure, broadleaf morphology, and abundant trichome coverage. Many community reports reference a spicy, incense-like bouquet layered over earthy base notes, which aligns with chemotypes rich in myrcene, beta-caryophyllene, and humulene. The result is a sensory profile that feels timeless—less candy, more cedar chest and spice market.
From an agronomic standpoint, Iraqi 66 can be forgiving, especially for growers who manage humidity and airflow carefully. It thrives with moderate feeding, strong light, and a dialed-in environment, showing best results when canopy density and late-flower moisture are controlled. Its finishes are typically prompt for an indica, often in the 8–9 week range indoors, with outdoor harvests landing from late September to mid-October in temperate latitudes.
This article consolidates what is known about Iraqi 66—its backstory, morphologies, chemistry, and cultivation—while acknowledging the gaps in publicly verifiable genealogy. Where formal lab data are limited, we contextualize the strain using established indica benchmarks and agronomic best practices. Throughout, we connect the dots using reputable breeder context and publicly available resources that track lineage and cultivation knowledge.
History
Bodhi Seeds has long been associated with authentic, old-world cannabis expressions, and Iraqi 66 fits this ethos. The breeder’s reputation is rooted in sourcing and stewarding heirloom lines, then creating accessible seed releases for growers. Iraqi 66 is widely discussed as a selection derived from Iraqi-origin stock, with the number likely denoting a cut, line, or selection identifier used during breeding and stabilization.
Public databases sometimes leave Middle Eastern heirlooms under-documented, which shapes how strains like Iraqi 66 appear in community catalogs. Seed-finder style repositories often include placeholders such as unknown or unconfirmed ancestry notes when breeder lineages weren’t formally published or validated. This is common for cultivars drawn from regions where seed circulation historically happened through informal networks rather than commercial registries.
This informational context is echoed by genealogy listings that group many heritage lines under generic or unknown labels due to sparse documentation. Such listings signal that while the cultivar is real and cultivated, fine-grained parentage records may not be fully traceable in the public domain. The consequence is a narrative built partly through breeder statements, grower experiences, and phenotype descriptions rather than hard lineage charts.
Despite these gaps, the cultivar’s performance and sensory traits provide meaningful continuity with its purported Iraqi roots. The resin-forward flowers, incense-earth aromatics, and calm-heavy effect profile align with many Middle Eastern hash cultivars cataloged over decades. With Bodhi Seeds as the steward, Iraqi 66 carries the breeder’s hallmark of authenticity and careful selection, even if its precise pedigree remains partially opaque.
Genetic Lineage
The verified details are that Iraqi 66 was bred by Bodhi Seeds and exhibits a mostly indica heritage. Beyond that, the precise parent lines have not been formally published in breeder notes that are widely cited. In a number of public databases, Middle Eastern source lines often appear under umbrella or unknown ancestry, consistent with the limited documentation of heirloom cannabis genetics.
In this context, Iraqi 66 is best understood as an indica-forward cultivar anchored by Iraqi landrace influence, stabilized and released by Bodhi. The number suffix suggests an internal selection or pheno label, a common practice during the breeder’s multi-generation selection work. This would match Bodhi’s methodology: start with a compelling heirloom population, hunt for desirable chemotypes and morphology, and preserve those traits in seed form.
While exact percentages of indica/sativa are not formally quantified, grow reports consistently describe compact plants, broad leaves, rapid floral onset, and a relatively short flower cycle—classic indica markers. These traits correlate with alleles typically selected in harsh, arid climates where fast finishing and dense resin protect the plant. The hash-friendly trichome coverage and thick, greasy resin are additional phenotypic clues pointing to a Middle Eastern indica background.
For growers comparing Iraqi 66 to other Bodhi lines, expect less fruit/candy influence than modern dessert hybrids and more of a grounded, herbal-spice profile. The genetic emphasis favors functional resin and calm-forward effects rather than high-THCV, racy sativa traits. Until breeder-released lineage notes are posted, Iraqi 66 remains a compelling example of how authentic heritage selection can stand on its own, even without an explicit family tree chart.
Appearance
Iraqi 66 typically grows with a short to medium stature indoors, often finishing between 80 and 120 cm in height without aggressive training. The plant shows a compact, bushy habit, with tight internodal spacing and pronounced apical dominance unless topped. Broad, dark green leaflets are common, reflecting its indica-dominant nature and strong chlorophyll expression.
During bloom, calyxes stack densely to form firm, conical to spear-shaped colas with a strong calyx-to-leaf ratio. Sugar leaves are modest in length and often heavily frosted, reducing trimming time compared to fluffier hybrid flowers. As flowers mature, pistils shift from creamy white to amber or rust, adding visual depth to the canopy.
Trichome production is a defining characteristic, with a thick carpet of glandular heads that shimmer in strong light. This resin is typically greasy and tenacious, a trait hashmakers value for both mechanical separation and solventless pressing. Growers frequently note a generous proportion of bulbous and capitate-stalked trichomes, linked to efficient cannabinoid and terpene storage.
In optimized environments, colas exhibit minimal foxtailing and maintain a tight structure that dries and cures without excessive shrink. Under lower humidity, the plant holds density well, but in high humidity, its compact flowers demand vigilant airflow to avoid moisture traps. Overall bag appeal is strong, emphasizing classic indica aesthetics—dense, glistening, and substantial in the hand.
Aroma
Aroma expresses an old-world spectrum: earth, dry incense, black tea, and cedar shavings over a base of warm spice. Many phenotypes add nuances of cracked pepper, cumin, and faint leather, hinting at high beta-caryophyllene and humulene content. Subtle herbal facets—bay leaf, thyme, and faint sage—can appear as the flower dries and cures.
In fresh-ground flower, a sweet, resinous undercurrent sometimes peeks through, reminiscent of date syrup or unrefined sugar. This sweetness is understated compared to dessert-forward hybrids and functions more as a binding note across the spiced-earth profile. Curing for 3–5 weeks at 60–62% RH often deepens the incense and tea notes while smoothing any greenness from an early dry.
Environmental factors affect aromatic intensity, with warmer daytime temps and lower humidity during late bloom promoting terpene retention and expression. Sulfur management before flower and adequate sulfur availability during bloom can enhance terpene biosynthesis, improving aromatic fidelity. Post-harvest handling—slow dry around 60°F/60% RH for 10–14 days—preserves the strain’s finer top notes.
Flavor
On inhalation, Iraqi 66 leans earthy-spice with a dry, woody edge—think cedar plank and toasted pepper. The mid-palate develops a smooth, resinous feel, revealing hints of black tea, clove, and lightly charred herbs. Exhale often lands with a soft incense finish and a lingering, almost umami-like savoriness.
Vaping between 175–190°C highlights subtler terpenes like linalool and ocimene, rounding out the sharper spice with floral and herbal sweetness. Combustion skews the profile toward wood and pepper but maintains the incense baseline if the cure is well-managed. For hash and rosin, expect a concentrated version of the same spectrum, with a deeper, oil-rich palate and a long finish.
Water-cured or aggressively dried flower will mute the tea and herb notes, so a careful slow dry is essential to retaining character. Properly jarred buds continue to mature in flavor over 4–8 weeks, harmonizing spice and wood into a cohesive profile. Paired with beverages, Iraqi 66 complements black teas, peated whiskies, and oolong, which echo its smoky, tannic edges.
Cannabinoid Profile
Formal, peer-reviewed lab datasets on Iraqi 66 are limited in the public domain, but indica-forward Bodhi selections typically show moderate-to-high THC with low CBD. Community-reported test panels for comparable Bodhi indicas often fall in the 16–22% THC range, with outliers below and above depending on phenotype and cultivation. CBD is usually minor (<1%), and CBG frequently appears in the 0.2–1.0% range in flower.
Minor cannabinoids may include trace THCV and CBC, though these are typically measured at low levels in indica landrace-influenced lines. Decarboxylation efficiency and curing practices can shift final measurements by several percentage points. Grow environment, harvest timing, and post-harvest handling can meaningfully influence potency, with suboptimal drying known to degrade THC into CBN over time.
From a pharmacological standpoint, a 16–22% THC cultivar with beta-caryophyllene, myrcene, and humulene dominance tends to produce strong body relaxation with moderate psychoactive intensity. Many users find this profile accessible at moderate doses, particularly in the evening. Those with low tolerance should start with small inhalation doses or edibles at 2.5–5 mg THC and titrate upward to avoid next-day lethargy.
For extractors, solventless rosin yields from resinous indicas can range widely, often from 15–25% of dry flower weight under optimized conditions. Bubble hash returns on fresh frozen may range between 3–6% of input weight, depending on trichome head size and cultivar-specific morphology. Variability is driven by phenotype, grow technique, harvest timing, and wash methodology.
Terpene Profile
Iraqi 66’s terpene ensemble is frequently described as myrcene-forward, supported by beta-caryophyllene and humulene, with contributions from limonene and linalool. In indica cultivars with similar sensory outputs, myrcene commonly ranges from 0.5–1.5% of dry weight, while beta-caryophyllene often lands between 0.2–0.8%. Humulene may appear at 0.1–0.4%, and limonene and linalool frequently occur in the 0.05–0.5% range.
Beta-caryophyllene is notable as a CB2 receptor agonist, which may contribute to perceived anti-inflammatory effects in some users. Myrcene is frequently associated with body relaxation and, in some models, enhanced permeability and potential sedation synergy with THC. Humulene contributes woody, earthy, and slightly bitter herbal tones that align with the strain’s cedar and tea aromatics.
Limonene, when present at moderate levels, can add a faint citrus lift that brightens the mid-palate without turning the profile into fruit-forward territory. Linalool, even in modest quantities, smooths the bouquet with floral and lavender hints, which some users interpret as calming. The balance of these terpenes is sensitive to environmental and nutritional variables, notably sulfur, potassium, and micronutrient availability during bloom.
Growers can encourage terpene density by maintaining late-flower temperatures at 68–75°F (20–24°C) during lights-on and 62–68°F (17–20°C) at lights-off. Keeping VPD within target ranges and RH in the 42–50% band from weeks 6–9 of bloom can help preserve volatile compounds. Gentle handling during harvest, minimal rough trimming, and low-and-slow drying are crucial to retaining Iraqi 66’s complex top notes.
Experiential Effects
Most users characterize Iraqi 66 as calming, body-centric, and gently sedative at higher doses. The headspace is typically clear to softly fuzzy, with reduced rumination and a steadying effect on mood. Across community reports for comparable indica chemotypes, onset after inhalation often occurs within 5–10 minutes, with peak effects at 30–60 minutes and a 2–4 hour duration.
At lower doses, the cultivar can produce a warm, grounded ease suitable for winding down or creative focus without overactivation. At higher doses, couchlock and heavy eyelids become more likely, especially if harvested with 10–20% amber trichomes. Some users report an appetite increase within an hour, which is consistent with THC’s influence on the endocannabinoid system.
Side effects resemble other THC-dominant indicas—dry mouth and dry eyes are common, and in sensitive individuals, transient dizziness can occur on standing. Anxiety is less commonly reported with indica-forward profiles than with high-THC sativas, but set and setting remain important. Users new to cannabis should consider microdosing strategies and avoid combining with alcohol or sedative medications.
For sleep, many find Iraqi 66 effective in the last hour of the evening, especially in low-light, screen-free environments. A small inhaled dose 30–60 minutes before bed often suffices, whereas edibles (2.5–5 mg) may be more appropriate for longer-duration sleep support. Overconsumption can lead to morning grogginess, so titration is key.
Potential Medical Uses
Given its indica-leaning chemotype, Iraqi 66 may be useful for individuals seeking relief from pain, muscle tension, and sleep disruption. Evidence summaries from national academies and clinical reviews have concluded that cannabinoids, particularly THC-dominant formulations, can offer modest-to-moderate analgesic benefits for chronic pain. In patient-reported outcomes, a significant proportion of medical users—often over 50% in observational cohorts—report improved sleep quality when using THC-dominant flower in the evening.
The beta-caryophyllene content commonly seen in spice-forward indicas has been studied for potential anti-inflammatory and anxiolytic properties via CB2 receptor activity. Myrcene-rich profiles are frequently associated with body relaxation and reduced perceived discomfort, which can complement THC’s central analgesic effects. While this synergy is promising, individual responses vary, and controlled dosing remains important.
For anxiety-prone patients, low-and-slow dosing is recommended, as THC can be anxiogenic at high doses, particularly in unfamiliar settings. Patients often start with 1–2 inhalations or 2.5 mg oral THC, increasing by small increments every 2–3 days until desired effects are achieved. Combining Iraqi 66 with non-pharmacological sleep hygiene practices can produce better outcomes than cannabis alone.
Muscle spasticity and post-exertional soreness are other domains where indica-dominant strains are frequently reported to help. Topical preparations from resin-rich indicas sometimes provide local relief without systemic intoxication, which may be useful during the day. As with all medical use, consult a clinician familiar with cannabis, and avoid driving or operating machinery while under the influence.
Potential adverse effects include transient hypotension, impaired short-term memory, and next-day sedation at higher doses. THC can interact with medications metabolized by CYP450 enzymes, so medical oversight is recommended for polypharmacy. Patients with a history of psychosis or severe cardiovascular disease should approach THC with additional caution or avoid it altogether.
Comprehensive Cultivation Guide
Overview and plant vigor
Iraqi 66 grows vigorously in warm, moderately dry environments, reflecting its Middle Eastern heritage. Expect compact plants with stout lateral branching and strong apical dominance unless topped. Internodes are short, which allows high-density planting in sea-of-green (SOG) or even, well-scaffolded canopies in screen-of-green (SCROG).
The flowering window typically runs 8–9 weeks indoors, with many phenotypes finishing around day 56–63 from flip. Outdoors, harvest often falls from late September to mid-October at 35–45°N, depending on season length and rainfall. In arid and semi-arid climates, the strain can excel due to its resin density and natural tolerance of lower humidity.
Environment: temperature, humidity, and VPD
Seedling stage prefers 72–78°F (22–26°C) with 65–75% RH, targeting a VPD of 0.8–1.0 kPa for steady transpiration. Vegetative stage thrives at 75–82°F (24–28°C) with 55–65% RH, VPD 1.0–1.2 kPa. Flowering is best at 70–78°F (21–26°C) with 42–55% RH; late bloom (weeks 6–9) benefits from 40–47% RH and VPD of 1.2–1.4 kPa to deter botrytis.
Night temps 5–9°F (3–5°C) lower than day help maintain metabolic balance without stalling growth. Avoid sustained temps above 86°F (30°C) in late flower, which can volatilize terpenes and stress resin heads. Conversely, temps below 64°F (18°C) can slow maturation and risk nutrient uptake issues.
Lighting and DLI
Seedlings: 150–300 µmol/m²/s PPFD with an 18/6 or 20/4 schedule. Vegetative: 400–600 PPFD for 16–20 hours daily, targeting a DLI of 20–30 mol/m²/day. Early flower (weeks 1–3): 600–800 PPFD, DLI 30–35; mid-to-late flower (weeks 4–9): 800–900 PPFD, DLI 35–40.
CO2 enrichment to 800–1,200 ppm during bloom can support higher PPFD and increase biomass and resin density. Keep leaf surface temps 1–2°F (0.5–1°C) higher than ambient under high-intensity LEDs to maintain photosynthetic efficiency. Ensure uniform canopy penetration; Iraqi 66’s dense structure benefits from side lighting or reflective walls to reduce shadowing.
Media and pH
Soil and living soil mixes perform excellently, with a pH target of 6.2–6.8 and strong microbial activity. Coco coir and hydroponic systems deliver fast growth when pH is held at 5.8–6.2 and the root zone is well-oxygenated. In living soil, amend with compost, worm castings, and slow-release minerals; in coco/hydro, prioritize frequent, low-volume irrigation to maintain ideal EC.
For heavy resin expression, organic approaches with balanced nitrogen and sufficient sulfur and micronutrients in bloom can enhance aromatic density. If using tap water, aim for Ca 50–100 ppm baseline and supplement to a root-zone target of Ca 120–180 ppm and Mg 40–60 ppm. Avoid bicarbonate levels above 120 ppm, which can cause pH drift and nutrient lockout.
Nutrition and EC targets
Vegetative growth responds well to an NPK around 3-1-2, ramping EC from 1.0 to 1.6 as plants size up. Bloom nutrition should shift to approximately 1-2-3, with EC 1.8–2.2 under high light; sensitive phenotypes may prefer the low end of that range. Maintain sulfur availability (at least 60–80 ppm in bloom) to support terpene synthesis; keep K robust from weeks 3–6 for bud bulking.
Supplement Ca/Mg under LEDs to avoid interveinal chlorosis and blossom-end deficiencies in dense flowers. Foliar sprays of calcium and micronutrients are acceptable in veg but should be discontinued before flower sites form. Monitor runoff EC and pH weekly to catch early signs of salt accumulation or imbalance.
Irrigation strategy
In soil, water thoroughly to 10–20% runoff when the container reaches ~30–50% of its saturated weight. As a rule of thumb, 3-gallon pots often take 1.0–1.5 liters per irrigation; 5-gallon pots, 1.5–2.5 liters, depending on media and environment. In coco, multiple daily irrigations at 5–8% of container volume are common under strong light.
Drybacks of 20–30% in coco/hydro promote oxygenation and prevent root hypoxia. Use moisture meters or scale-based watering to avoid over- or under-watering, which can stress trichome production. Maintain solution temperatures at 65–70°F (18–21°C) to protect root health and avoid pythium.
Training and canopy management
Iraqi 66’s compact habit takes well to topping at the 4th–5th node, followed by low-stress training to spread the canopy. SCROG nets help distribute light evenly across dense tops and minimize larf. In SOG, run 9–16 plants per square meter in 1–3 gallon containers, flipping at 6–10 inches of height for uniform single-cola plants.
Defoliation should be moderate; remove inner fans that block airflow and light, especially at the flip and around week 3 of bloom. Avoid aggressive stripping in late flower, which can stress plants and reduce terpene expression. Stakes or trellis are advisable due to dense flower weight and compact architecture.
Pest and disease management
Iraqi 66 tolerates dry conditions but still demands proactive integrated pest management (IPM). Common threats include spider mites, thrips, and powdery mildew; scout weekly with sticky cards and leaf underside checks. Release predatory mites (e.g., Neoseiulus californicus, Phytoseiulus persimilis) in veg and early flower as a preventive.
Use neem or azadirachtin only in vegetative stages, and discontinue sulfur sprays at least 2 weeks before flower initiation to prevent residue on buds. For caterpillars outdoors, Bacillus thuringiensis (Bt) applications at dusk can reduce damage without harming beneficials. Maintain airflow of 0.3–0.6 m/s across the canopy and ensure 10–15 air exchanges per hour indoors to mitigate mold risk in dense colas.
Flowering timeline and cues
Weeks 1–2: stretch is modest for an indica, typically 30–60% height increase from flip. Weeks 3–5: calyx stacking intensifies; begin K and P emphasis while keeping N sufficient to prevent yellowing. Weeks 6–8/9: resin swells, pistils recede, and terpene intensity peaks; lower RH to 40–47% to safeguard against botrytis.
Trichome monitoring is essential; harvest at 5–10% amber and 70–85% cloudy for a balanced effect. For a deeply sedative profile, allow 10–20% amber development, acknowledging a potential small THC-to-CBN shift. Always cross-reference trichome maturity with aroma peak and calyx swell for optimal timing.
Yield expectations
In well-managed indoor SCROG, Iraqi 66 can produce 450–600 g/m² with strong light and CO2. SOG setups with uniform single-cola plants may approach the upper range due to efficiency in canopy fill. Outdoors in 25–50 gallon containers or in-ground beds, yields of 500–1,000 g per plant are reasonable in favorable climates.
Solventless rosin yields vary by phenotype but can be robust thanks to greasy resin. Hash-focused phenotypes with strong 90–120 µm head distribution tend to wash more efficiently, sometimes achieving 3–6% fresh frozen return under skilled technique. Phenohunting for trichome head size and stem strength can significantly impact extraction outcomes.
Outdoor and latitude considerations
Iraqi 66 fares best in regions with warm days, cool nights, and limited late-season rainfall. At 35–45°N, plan to plant after final frost and harvest from late September to mid-October, watching weather windows for rain events. Canopy thinning and proactive caterpillar management are crucial in regions with moth pressure.
Mulch and smart irrigation scheduling reduce root stress during heat waves; target deep waterings in the early morning. In coastal or humid climates, greenhouse cultivation with dehumidification may be preferable to avoid botrytis in dense flowers. Consider strain placement for maximum sun exposure—south-facing, wind-sheltered sites are ideal.
Harvest, dry, and cure
Wet-trim only lightly to preserve trichomes and reduce handling; remove fan leaves and leave sugar leaves intact to slow the dry. Aim for 60°F (15.5°C) and 60% RH for 10–14 days, with gentle air movement not directly on the flowers. Stems should snap rather than bend before jarring.
Cure in glass jars at 62% RH, burping daily for the first week then weekly for 3–4 weeks. Aromatics typically open up significantly by week 3–5 of cure, enhancing the tea, incense, and spice notes. Avoid overdrying below 55% RH, which flattens the flavor and increases harshness.
Seed type and sourcing notes
Bodhi Seeds is known for releasing regular (non-feminized) seeds, which appeals to breeders and those seeking hardy plants. Growers choosing feminized seeds in general should consider the typical pros and cons highlighted by mainstream cultivation guides: feminized ease of canopy filling versus regular seeds’ genetic breadth and vigor. If running regular seed, plan for plant counts that allow sexing and selection during early flower.
Data context and verification
Genealogy catalogs sometimes label heritage lines as unknown when breeder documentation is sparse or not publicly linked. This is common for Middle Eastern cultivars and does not detract from practical cultivation knowledge. When possible, verify current breeder notes and community grow logs to align environmental targets and phenotype expectations for your specific lot.
