Written by Ad OpsOrigins and Breeding History
Blue Auto Mazar is a feminized, autoflowering cultivar developed by Dutch Passion, a legacy breeder operating since 1987. It sits within their Blue Family, combining heritage Blueberry aromas with the robust structure and yield of Auto Mazar.
Dutch Passion’s own materials describe Blue Auto Mazar as uncomplicated, easy to grow, and well suited to both indoor and outdoor environments. In company blog features, the strain consistently appears in lists of top-performing autoflowers for Sea of Green (SOG) setups and quick, reliable harvests.
The breeding objective was straightforward: fuse the terpene-rich, fruity profile of Blueberry with the high-yield, Afghani-backed vigor of Mazar, then lock the autoflower trait through stabilized Ruderalis genetics. The result is a compact, fast cultivar that rarely exceeds 10–11 weeks from seed to harvest.
Notably, Blue Auto Mazar has also served as a parent in newer fruity autos, such as Strawberry Cough x Blue Auto Mazar highlighted by Dutch Passion. That role as a building block reflects its reliable terpene output, predictable structure, and consistent finishing times.
Genetic Lineage and Inheritance
At its core, Blue Auto Mazar descends from Blueberry and Auto Mazar, the latter being a Mazar line endowed with Ruderalis genes for autoflowering. Blueberry, originally popularized by DJ Short, traces to Afghan indica, Thai sativa, and Purple Thai, imparting berry-forward terpenes and vivid coloration.
Mazar contributes a heavy Afghani indica backbone known for dense flowers and resin production. When crossed into an autoflower framework, it confers short internodes, sturdy lateral branching, and a strong calyx-to-leaf ratio.
The Ruderalis contribution fixes the photoperiod independence, typically initiating bloom automatically by weeks 3–5 post germination. This trait, combined with the indica-leaning structure, leads to compact plants that finish reliably in 70–75 days under optimized conditions.
Phenotypically, growers can expect indica-dominant morphology with occasional purple-blue hues, especially under cooler nighttime temperatures. Genotype-wise, the line is stabilized for repetitive performance, making it a top candidate for SOG where uniformity reduces canopy management labor.
Morphology and Visual Appeal
Blue Auto Mazar typically reaches 60–100 cm indoors, depending on pot size, light intensity, and photoperiod (18/6 vs 20/4). In SOG, many growers report plants clustering around 60–80 cm for tidy colas and simpler airflow management.
The plant is characterized by broad-fingered fan leaves and tight internodal spacing, a nod to its Afghani ancestry. Buds tend to be golf-ball to soda-can sized along the main stem, culminating in a dense terminal cola.
Coloration can range from deep forest green to sapphire and plum shades, especially as night temperatures drop by 5–8°C in late bloom. The Blueberry heritage predisposes the plant to anthocyanin expression that becomes more pronounced in the final two weeks.
Trichome coverage is heavy, with a frosty, sparkling glaze that often creeps onto nearby sugar leaves. Burnt-orange pistils weave through the buds at maturity, making contrast-rich flowers that are visually striking in jars and on the branch.
Caliper measurements of mature colas commonly exceed 3–4 cm in diameter, especially in higher-PPFD rooms. The calyx-to-leaf ratio is favorable for hand or machine trimming, reducing post-harvest labor by an estimated 15–25% compared to leafier autos.
Aroma and Bouquet
Blue Auto Mazar’s aromatic signature blends ripe blueberry jam and forest berries with Afghan hash, pine resin, and gentle pepper spice. The bouquet opens sweet and fruity, then resolves into earthy, slightly incense-like bass notes.
The terpene profile aligns with Dutch Passion’s data sheet callouts: ocimene and caryophyllene are present, with alpha-pinene also recognized by their terpene resources. Together, these compounds produce a refreshing and nuanced nose that evolves noticeably between grind and exhale.
Freshly cured jars often show a high-contrast aroma: berry top-notes jump out immediately, while peppery caryophyllene and coniferous pinene add depth within seconds. As buds age, the jammy sweetness deepens and the spicy-resinous character intensifies.
In living rooms or small grow tents, a single plant can scent the air with moderate intensity by mid-flower. Carbon filtration at the 200–400 m³/h range per square meter of canopy is usually sufficient to maintain odor control indoors.
Flavor and Consumption Notes
The flavor tracks the aroma closely, delivering blueberry preserves on the inhale and a peppery, pine-resin finish on the exhale. Earthy hash notes linger on the palate, adding a classic Afghani warmth and mouth-coating depth.
Vaping reveals especially clear berry-chamomile sweetness at lower temperatures and more resin-forward spice at higher temps. Many users report the flavor holding through the first 2–3 pulls before gradually shifting toward spicy-woody tones.
Dutch Passion’s terpene guide notes alpha-pinene’s vaporization near 311°F (155°C), a useful anchor for dialing in terp preservation on a dry herb vaporizer. Starting around 170–180°C can maximize fruit and floral tones, while 190–200°C unlocks more of the resin-pepper complexity.
In combustion formats, a clean white ash is common after a proper cure, with smoothness rated high by many home growers. In one Dutch Passion review roundup, four Blue Auto Mazar plants finished in roughly 12 weeks and earned a 9/10 smoke rating, highlighting both flavor satisfaction and ease of cultivation.
Cannabinoid Composition and Potency
Blue Auto Mazar generally produces THC in the mid-to-high teens, with many modern grows reporting 16–20% THC under efficient LED lighting. Optimized environments with high PPFD and balanced nutrition can nudge potency into the 18–22% range, though results vary by phenotype and grower skill.
CBD is typically low, often under 0.5%, keeping the chemotype clearly THC-dominant. Minor cannabinoids like CBG and CBC may appear in trace amounts (e.g., 0.1–0.6% combined), contributing subtly to the entourage effect.
From a user-experience standpoint, this potency level is strong enough for meaningful relief and pronounced euphoria without guaranteed couch-lock. Dose titration remains important, as autos with high-density trichomes can deliver unexpectedly robust effects for newer consumers.
In comparative terms, Blue Auto Mazar’s potency aligns with many top-tier autos released in the last five years. Advances in autoflower breeding have narrowed the historical gap with photoperiods, and this cultivar exemplifies that trend with repeatable potency in compact cycles.
Terpene Spectrum and Chemistry
Ocimene, caryophyllene, and alpha-pinene anchor Blue Auto Mazar’s terpene identity, according to Dutch Passion resources. Ocimene contributes sweet-herbal, floral brightness, caryophyllene adds pepper-spice and interacts with CB2 receptors, and alpha-pinene provides pine, resin, and mentally clarifying nuances.
Total terpene content for healthy indoor runs commonly ranges between 1.2% and 2.5% by dry weight, with standouts exceeding 3%. Within that total, caryophyllene often registers around 0.3–0.9%, while alpha-pinene and ocimene each may populate the 0.1–0.6% band depending on phenotype and environment.
Pinene’s reported vaporization around 155°C (311°F) makes it a prime target for low-temp vaping to preserve foresty freshness. Caryophyllene, a sesquiterpene, is heavier and tends to bloom at slightly higher temps, explaining the peppered exhale as heat increases.
Ocimene is highly aromatic yet volatile, and its bright fruit-floral lift tends to fade fastest if curing conditions are too warm or dry. Maintaining a 62% relative humidity and cool, dark storage helps preserve this top-note, making the first two months of curing particularly rewarding for flavor seekers.
Effects and User Experience
Blue Auto Mazar leans into a calm, body-forward experience with a cheerful, head-light euphoria. The onset is usually quick when inhaled, often in the 2–5 minute window, with a crescendo peaking at 30–45 minutes.
Users frequently report muscle looseness and reduced physical tension without a heavy sedative crash at moderate doses. The mental effect is relaxed and content, often described as “clear enough to hold a conversation, mellow enough to unwind.”
At higher doses, the indica backbone can surface more prominently as couch-lock and drowsiness, especially late in the evening. In that range, many find it compatible with movies, music, or sleep preparation.
Tolerance, set and setting, and route of administration strongly influence the experience, making microdoses a smart starting point for new consumers. Edible conversions can extend the duration to 4–6 hours, while vaping and smoking usually resolve within 2–4 hours.
Therapeutic and Medical Potential
Nothing here is medical advice, but the cultivar’s profile suggests several potential areas of interest. The caryophyllene component is unique among common terpenes as a CB2 receptor agonist, a pathway linked to inflammation modulation in preclinical work.
Alpha-pinene may counter some THC-associated short-term memory effects and promote a sense of mental clarity, according to terpene literature. For some users, this makes Blue Auto Mazar feel less foggy than heavier myrcene-dominant strains at comparable THC levels.
Anecdotally, users mention relief around muscle tension, general stress, and sleep onset, especially at higher doses. Lower doses are often preferred for daytime relief, where relaxation without sedation is the goal.
Patients targeting neuropathic pain or spasticity sometimes favor indica-leaning chemotypes with peppery caryophyllene signatures. That said, individual responses vary widely, and lab verification plus personal titration remain best practices.
Cultivation Guide: Indoors, SOG, and Outdoors
Dutch Passion highlights Blue Auto Mazar as uncomplicated and easy to grow, often ready around 70–75 days from germination, with a broader seed-to-harvest window of 10–11 weeks. This speed makes it ideal for perpetual harvests and for fitting multiple cycles into a single outdoor season in temperate climates.
For SOG, Dutch Passion specifically recommends Blue Auto Mazar due to its uniform structure and compact size. In practical terms, growers often run 9–16 plants per square meter in 7–11 L pots, aiming for one dominant cola per plant and minimal training.
Indoors, an 18/6 or 20/4 light cycle is standard throughout life, with 20/4 offering small but measurable increases in daily light integral (DLI). Target PPFD of 500–700 µmol/m²/s in weeks 1–3 and 800–1,000 µmol/m²/s through bloom typically yields dense, resinous flowers without excessive stretch.
Temperature targets of 24–26°C day and 20–22°C night maintain brisk metabolism, with late-flower night drops to 18–20°C encouraging color. Relative humidity at 60–65% early, 50–55% mid, and 45–50% late flower aligns with a VPD of roughly 0.8–1.1 kPa in veg and 1.2–1.5 kPa in bloom.
Substrates that drain quickly and hold air—coco/perlite 70/30, light-mix soil, or rockwool—help autos reach peak speed. Fabric pots (11–19 L for single plants, 7–11 L for SOG) balance root-zone oxygenation and moisture buffering, reducing overwatering risk.
Nutrient strategy should remain moderate and steady, as autos dislike early overfeeding. In inert coco, aim for 1.2–1.4 EC in early growth and 1.6–1.8 EC in peak bloom, with runoff pH 5.8–6.0; in soil, irrigate with 6.3–6.6 pH solutions and watch the plant for visual cues.
Blue Auto Mazar’s autoflower timing means training must be gentle and early. Low-stress training (LST) from days 10–21 can open the canopy, while topping is best avoided or done once by day 14–18 on vigorous phenos only.
Outdoors, the 10–11 week seed-to-harvest window allows 2–3 successive cycles in warm regions and at least two in many temperate zones. Plants typically reach 60–100 cm, with yields of 50–120 g per plant under average sunlight and 120–200 g in optimal, high-DLI summers.
Dutch Passion’s own blog case studies note 12-week finishes producing heavy yields and a 9/10 smoke rating from home growers. Those results align with grams-per-watt efficiencies of 1.0–1.5 g/W under modern full-spectrum LEDs when environmental controls are on point.
Feeding, Training, and Integrated Pest Management (IPM)
Begin with a mild nutrient solution and ramp evenly, as autos have limited time to recover from excess EC. A 3-1-2 NPK ratio in early growth, shifting toward 1-2-3 by weeks 4–7, often matches the plant’s uptake curve.
Calcium and magnesium requirements rise under LED lighting; 0.3–0.5 EC worth of Ca/Mg supplementation in coco helps avoid interveinal chlorosis. In soil, consider a top-dress of calcium carbonate and magnesium sulfate at week 3 if the cultivar shows hungry behavior.
Irrigation to 10–20% runoff every 1–2 days in coco prevents salt accumulation and supports steady growth. In soil, water less frequently but to full saturation, allowing a light dry-back to keep the rhizosphere oxygenated.
For training, LST is safest and delivers a consistent 10–20% yield bump by better light distribution. Defoliation should be modest—remove only the most obstructive fan leaves around day 21 and day 35 to preserve photosynthetic capacity in a short lifecycle.
Preventative IPM reduces the chance of costly mid-flower interventions. Apply biologicals like Bacillus subtilis or Bacillus amyloliquefaciens in veg to prevent powdery mildew, and release predatory mites (e.g., Amblyseius swirskii) early if your region is pest-prone.
If outdoor, scout weekly for caterpillars and leaf miners; Bacillus thuringiensis var. kurstaki (BT) sprayed at dusk in veg is highly effective. Avoid oil-based sprays after week 3 of flower to protect trichomes and prevent residue on finished buds.
Maintain strong airflow—at least one oscillating fan per 0.5–1 m²—plus a matched carbon filter to control aroma. In dense SOG runs, a floor-to-ceiling laminar airflow path reduces microclimates and keeps VPD stable across the canopy.
Harvest Timing, Drying, and Curing
Blue Auto Mazar often reaches maturity at 70–75 days from germination, though some phenos benefit from an extra week for terpene development. Trichome checks are best practice: harvest around cloudy with 5–15% amber for a balanced effect, or 20–30% amber for heavier sedation.
Flushing for 7–10 days in inert media improves ash quality and flavor clarity. In living soil, simply taper nitrogen inputs and provide microbe-friendly teas in the final two weeks.
Dry in a dark, clean space at 18–20°C and 50–55% relative humidity for 10–14 days, targeting 0.8–1.0 kPa VPD to slow evaporation. Gentle, slow drying preserves ocimene and other volatiles that can otherwise dissipate rapidly.
Cure in airtight glass jars at 62% RH, burping daily for the first week and every 2–3 days thereafter for another two weeks. Most users notice a step-change in flavor and smoothness between weeks 2 and 4 of curing, with berry notes gaining definition.
For long-term storage, maintain a cool, dark environment—ideally 15–18°C—to slow terpene oxidation. Properly stored flowers can retain 80–90% of their original aromatic intensity for several months, with only gradual shifts toward deeper, resinous tones.
Yield Expectations and Real-World Case Studies
In SOG under efficient LEDs, Blue Auto Mazar typically produces 400–550 g/m² with a skilled hand, with outliers pushing higher under CO2 and dialed environments. On a per-plant basis in 7–11 L pots, expect 40–90 g, while larger single-plant runs in 15–19 L containers can clear 120–180 g.
Grams per watt commonly land around 1.0–1.5 g/W in well-managed rooms at 800–1,000 µmol/m²/s PPFD. Outdoors, 50–120 g per plant is achievable in average sun, with 150–200 g reports in Mediterranean summers or high-altitude sites with strong DLI.
Dutch Passion’s own blog highlights a home grow where four Blue Auto Mazar plants finished in roughly 12 weeks and delivered heavy yields with a 9/10 smoke rating. That dataset dovetails with wider community results ranking the cultivar highly for reliability, speed, and flavor retention.
For planning purposes, assume a harvest every 10–11 weeks from a staggered SOG pipeline, translating to 4–5 indoor harvests per year. This cadence allows small home setups to generate steady supply with minimal downtime for cleaning and reset.
Why Blue Auto Mazar Excels in SOG
Dutch Passion explicitly singles out Blue Auto Mazar as a strong Sea of Green candidate, and the morphology explains why. The plant grows a dominant central cola with short lateral branches, producing a canopy of uniform, dense tops.
Uniformity is the cornerstone of SOG efficiency because it lets you optimize light height and intensity without managing dozens of distinct plant profiles. With Blue Auto Mazar, 9–16 plants per square meter is a comfortable range, allowing quick canopy establishment by days 21–28.
Because the cultivar finishes in approximately 70–75 days, SOG growers can maintain a two-tier or three-tier rotation to harvest every 3–4 weeks. This spreads risk and creates a consistent pipeline of fresh flowers without complex training or long veg times.
Yield per plant is less important than yield per square meter in SOG, and Blue Auto Mazar’s dense terminal colas shine here. The cultivar’s ease-of-grow rating from Dutch Passion, combined with its terpene-forward profile, balances speed and quality in a way few autos achieve.
Environmental Optimization and Advanced Tips
Light: Aim for a DLI of 35–45 mol/m²/day in bloom, which corresponds to 800–1,000 µmol/m²/s PPFD over a 20-hour photoperiod. If running 18/6, increase PPFD slightly or accept a modest DLI reduction; both schedules can produce top-tier results.
CO2: Supplemental CO2 at 900–1,100 ppm can improve growth rate and density if—and only if—light, temperature, and nutrition are already optimized. Autos respond to CO2, but the short lifecycle means returns are modest compared to photoperiods; expect single-digit percentage gains.
Irrigation automation: In coco, 2–4 small irrigations per lights-on period with 10–15% runoff stabilize EC and speed metabolisms. Drip rings or multi-emitters per pot improve uniformity across dense SOG tables.
Root-zone: Keep media temperatures 20–22°C; cold roots can slow autos dramatically, lengthening finish by 5–10 days. Conversely, hot root zones above 24–25°C risk oxygen deprivation and opportunistic pathogens.
Stress management: Avoid transplant shock by starting in final pots or using air-pruning plugs before a single, early transplant at day 7–10. Photoperiod stress is less relevant in autos, but consistent light intensity and gentle handling still translate to thicker stems and denser flowers.
Terpene preservation: Limit canopy temperatures to ≤26°C late bloom and keep night-time RH under 50% to retain volatile top-notes like ocimene. Gentle air movement across buds, rather than direct fan blasts, reduces terpene stripping and micro-tearing of trichome heads.
Common Pitfalls and How to Avoid Them
Overfeeding early is the most common mistake with autos, and Blue Auto Mazar is no exception. Start at half-strength nutrients for the first 10–14 days and increase only when the plant shows steady, vigorous growth.
Aggressive high-stress training (HST) can stall growth in a cultivar that transitions to bloom quickly. If topping at all, do it once between days 14–18 on a fast, healthy plant; otherwise, stick to LST and minor leaf tucking.
Excess humidity late flower invites botrytis in dense colas. Keep late-bloom RH at 45–50% with robust exhaust and oscillating fans to sweep moisture from the top 10–15 cm of the canopy.
Neglecting root oxygen is another silent yield killer. Use fabric pots or air pots, ensure consistent dry-backs, and avoid compacted media to protect the fine feeder roots that drive nutrient uptake.
Strain Pairings and Use Cases
For daytime creativity with related flavor, pair Blue Auto Mazar with a citrus-forward sativa in small doses to lift energy without overpowering the palate. The berry base harmonizes with limonene-rich strains, producing a fruit-salad bouquet.
For evening unwinding, a straight Blue Auto Mazar session at moderate dose often provides enough relaxation without immediate sedation. Adding a myrcene-heavy varietal later can intentionally deepen the body effect for sleep.
Culinary extractions—particularly rosin chips or low-temp ethanol washes—capture its blueberry-jam notes well. Keeping extraction temperatures low helps protect ocimene and pinene, which otherwise volatilize quickly.
Legal, Ethical, and Safety Considerations
Always follow local laws regarding the cultivation and possession of cannabis. Dutch Passion’s own site reminds buyers that cultivation may not be legal where they live, and due diligence is essential.
From a safety perspective, start low and go slow, especially when switching from one route of administration to another. For inhalation, allow 10–20 minutes between sessions to gauge effects; for edibles, wait at least 2 hours before redosing.
Grow ethically by managing waste, using biological pest controls where possible, and filtering exhaust air to limit odor nuisance. Responsible cultivation fosters goodwill with neighbors and helps normalize the home-grow community.
