Written by Ad OpsOrigins and Breeding History
Auto Somachigun is an autoflowering cannabis variety bred by Biohazard Seeds, a European breeder known for robust, resin-forward hybrids. In the context of modern autoflower development, Auto Somachigun arrived as part of a broader push in the 2010s to close the potency and yield gap between autos and photoperiod strains. The breeder positioned it as a complete hybrid drawing on ruderalis, indica, and sativa heritage to deliver speed without sacrificing complexity.
Autoflower strains in general have advanced rapidly over the past decade, with independent lab reports across the industry showing THC in autos rising from low teens around 2012 to routinely 18% or higher by the early 2020s. Auto Somachigun fits this trend, frequently reported by growers as a high-potency auto with dense, resinous flowers. The name hints at a punchy, rapid-fire performance, while the genetic architecture aims for balanced effects suitable for day or evening use.
Because Biohazard Seeds has not widely publicized the exact photoperiod parents, transparency centers on the trait mix—ruderalis for autoflower timing, indica for body and resin, and sativa for uplift and aroma. Experienced cultivators recognize this tri-hybrid approach as the norm for modern autos that must deliver potency and flavor as well as speed. In practice, Auto Somachigun is positioned to complete its entire cycle in roughly 70 to 85 days from sprout under 18 to 20 hours of light.
The breeding process for stable autoflowering typically requires several generations of selection, often reaching F4 to F6 before uniform auto expression approaches 98% to 100%. This level of stability is essential so that the majority of seeds flower automatically regardless of light cycle. Auto Somachigun’s commercial release suggests it underwent a similar multi-generation refinement before distribution to growers.
In community circles, the strain has earned a reputation as a reliable, balanced auto that takes well to light training and performs in compact indoor setups. It emerged at a time when home growers demanded big photoperiod flavor and resin with auto convenience. Biohazard Seeds designed it to satisfy that demand without overcomplicating cultivation for beginners.
Genetic Lineage and Inheritance
Auto Somachigun’s lineage is described by the breeder as ruderalis, indica, and sativa, reflecting a composite genetic architecture. The ruderalis component supplies the day-neutral flowering gene that triggers bloom after a fixed juvenile period, independent of photoperiod changes. The indica influence often contributes broad-leaf morphology, tighter internodes, and heavier resin output.
The sativa component typically provides vigor, lateral branching, and a brighter terpene stack that can include citrus, tropical fruit, or floral notes. Together, the indica and sativa balance creates a hybrid effect footprint with both body relaxation and mental uplift. This balance is a hallmark of contemporary autos that avoid simple couchlock or jittery stimulation.
In breeding terms, achieving consistent autoflowering usually entails repeated backcrossing or stabilizing crosses to lock in day-neutral flowering. Growers commonly observe that by the F4 generation, most auto lines reach high fixation of the trait, with some seed lots hitting 98% or higher auto expression. While Biohazard Seeds has not published exact filial generation numbers, the commercial stability suggests multi-generation selection.
Phenotypically, Auto Somachigun tends to present as a compact to medium plant with a dominant central cola and symmetrical side branches. Internodal spacing commonly lands in the 2 to 5 centimeter range under sufficient light intensity, with several growers reporting low-stretch phenotypes that suit tents with limited height. The typical plant height indoors is approximately 60 to 100 centimeters when managed with light training.
Because precise photoperiod parents are undisclosed, it is prudent to evaluate each phenotype for specific nuances in aroma and effect. Some grow reports describe a fruit-forward expression with mango-citrus top notes, while others lean earthier and peppery, suggesting differing terpene emphasis across phenotypes. Despite these differences, the core hybrid structure remains consistent with balanced vigor and resin density.
Appearance
Auto Somachigun plants generally develop a stout, symmetrical frame with a prominent main cola. Side branches stack tight, golf-ball to spear-shaped buds, producing a balanced canopy that responds well to canopy management and even light distribution. The leaves tend toward a medium width, reflecting a hybrid leaf morphology rather than an extreme broad- or narrow-leaf profile.
As flowering advances, calyxes swell and tighten, giving flowers a dense, resin-glazed appearance. Trichome coverage is typically high, with visible frost on sugar leaves by week five to six of the cycle, under adequate lighting. The calyx-to-leaf ratio is favorable for easy trimming, which many small-scale growers appreciate at harvest.
Coloration is usually forest to lime green during mid-flower, with vibrant orange pistils that darken toward copper as the crop matures. Under cooler night temperatures, especially below 18 degrees Celsius late in bloom, some plants exhibit anthocyanin expression with soft purples along sugar leaves and calyx tips. This color shift is aesthetic and does not indicate distress if environmental parameters remain within optimal ranges.
Bud structure ranges from compact cluster formation to more conical spears on the main stem, depending on phenotype and light intensity. Well-managed plants with consistent PPFD often show uniform stacking and minimal larf at the lower canopy. This morphology allows Auto Somachigun to perform well in small tents with good vertical control.
Dried flowers retain a tight, crystalline surface with visible trichome heads if handled gently during trim and drying. The pistils compress and darken, and the underlying calyxes reveal a fine-grain structure that breaks up cleanly. Expect medium density that grinds smoothly without excessive moisture loss when cured at 60% relative humidity.
Aroma
The aroma of Auto Somachigun commonly blends tropical fruit, citrus zest, and a grounding layer of peppery spice. Many growers liken the top note to mango or ripe stone fruit, balanced by an earthy, herbal base. As flowers cure, a dash of diesel or woody balsamic nuance can emerge, likely tied to sesquiterpenes like caryophyllene and humulene.
Drying practices significantly influence aromatic expression. A slow dry of 10 to 14 days at 18 to 20 degrees Celsius and 58% to 62% relative humidity preserves volatile monoterpenes such as limonene and ocimene. Faster or hotter dries risk losing 20% to 40% of the most volatile aroma molecules according to post-harvest studies in cannabis and hops.
Freshly broken buds often release a burst of citrus and tropical esters accompanied by a green, herbal undertone. On the back end, nose-tingling spice and faint woodsy bitterness present as the jar airs out, hinting at caryophyllene and pinene contributions. After a four-week cure, the profile usually rounds out, with less grassy chlorophyll scent and more integrated fruit-spice.
Phenotypic variation can tilt the bouquet in different directions. Fruit-forward expressions emphasize limonene and myrcene, smelling sweeter and brighter. Earthier expressions weigh more heavily on caryophyllene-humulene, projecting a peppered herb and faint diesel character.
Overall intensity is medium to high, noticeable upon opening a jar but not overwhelming compared with sharply gassy cultivars. For discreet storage, airtight containers with odor-absorbing packs can reduce ambient scent by 30% to 50% in small spaces. Proper cure enhances both intensity and complexity without amplifying harshness.
Flavor
Auto Somachigun typically delivers a layered flavor that parallels its aroma while shifting in sequence across the inhale and exhale. The first impression is often citrus peel and tropical fruit, followed by a smooth, herbal sweetness. On the exhale, peppery spice and woody notes linger on the palate.
Vaporization at 175 to 190 degrees Celsius tends to accentuate limonene-bright top notes and a rounded sweetness from myrcene. Combustion emphasizes the spice and wood, with a mild resin finish. A well-cured sample should taste clean, without chlorophyll bite or harshness.
After two to four weeks of curing, many users report a 15% to 25% perceived increase in flavor intensity due to chlorophyll breakdown and continued terpene stabilization. By six to eight weeks, the profile becomes more integrated, with a seamless transition from fruit to spice. Over-curing past three months at fluctuating humidity can dull top notes and reduce brightness.
Grinding technique also affects flavor delivery. A medium grind provides even airflow and preserves trichome heads, while over-grinding can rupture resin and release bitterness. Freshly ground material typically tastes brighter and more layered than pre-ground storage.
Pairing with beverages can accentuate specific components. Sparkling water with a twist of lime or yuzu highlights citrus notes, while unsweetened green tea emphasizes herbal facets. Avoid heavily flavored drinks that can mask the more delicate terpene contributions.
Cannabinoid Profile
As an autoflowering hybrid, Auto Somachigun is commonly reported to produce moderate to high THC along with trace CBD. Grower-shared lab results and anecdotal tests often place THC between 16% and 22% by dry weight under optimized conditions. CBD typically remains low at around 0.2% to 0.6%, with minor cannabinoids like CBG appearing in the 0.2% to 0.8% range.
Total cannabinoid content can vary widely with cultivation practices. Indoor growers running 600 to 900 micromoles per square meter per second PPFD and maintaining environmental stability often reach the upper end of potency ranges. Outdoors, variability in light intensity, temperature swings, and pest pressure can lower cannabinoid totals by 10% to 25% compared with tightly controlled indoor environments.
Cannabinoid development peaks near the end of the flowering window. Trichome surveys show maximum THC correlates with a predominance of cloudy heads and minimal amber, commonly around 5% to 15% amber trichomes. Allowing more amber can increase cannabinol formation via THC oxidation, potentially changing the effect profile toward heavier sedation.
Extraction yields from resinous autos like Auto Somachigun are competitive with photoperiods when flower density is high. Hydrocarbon or rosin methods often return 15% to 25% yield by weight depending on input quality and moisture content. Cold-cured rosin preparations tend to preserve more volatile components, reflecting the fruit-forward character.
Because cannabinoid ratios are inherently phenotype- and cultivation-dependent, patients and connoisseurs seeking precise outcomes should verify lab results for each batch. Frequent testing provides a quantified basis for dialing in harvest timing to match the desired balance of uplifting versus relaxing effects. For home growers, investing in small-batch testing kits can provide trend data even if absolute accuracy is limited.
Terpene Profile
Auto Somachigun’s terpene spectrum typically leans on a myrcene-limonene-caryophyllene triad, yielding fruit, citrus, and pepper elements. Across multiple grow reports, total terpene content often falls around 1.5% to 2.5% of dry weight when dried and cured carefully. That level is considered robust for autos and supports the strain’s assertive bouquet.
Myrcene is frequently the lead terpene, reported in the 0.4% to 1.0% range, lending ripe fruit, herbal, and slightly musky tones. Limonene commonly appears in the 0.2% to 0.5% range, adding citrus bite and perceived brightness. Beta-caryophyllene typically measures around 0.2% to 0.6%, contributing peppery warmth and engaging CB2 receptors relevant to inflammatory pathways.
Supporting terpenes often include humulene at 0.1% to 0.3%, which adds woody, herbal dryness, and ocimene at 0.05% to 0.2% for floral-tropical lift. Alpha- and beta-pinene may sum to 0.05% to 0.2%, bringing subtle pine and potential cognitive clarity for some users. Linalool, when present around 0.05% to 0.15%, imparts a soft floral sweetness and may smooth the finish.
Terpene retention hinges on post-harvest conditions. Studies in cannabis show that temperatures above 22 degrees Celsius during drying can accelerate monoterpene loss, and sub-40% relative humidity can desiccate flowers, reducing aromatic depth. Maintaining a steady 60% RH in the jar helps preserve volatile fractions for at least eight to twelve weeks.
From an effects perspective, the myrcene-limonene-caryophyllene balance underpins Auto Somachigun’s hybrid feel. Myrcene may accentuate body relaxation, limonene contributes to mood elevation, and caryophyllene can temper discomfort by targeting CB2. This synergy aligns with user reports describing uplift without sharp edges and body comfort without immobilizing sedation.
Experiential Effects
Users often describe Auto Somachigun as a balanced hybrid with an early uplift followed by centered relaxation. Onset after inhalation arrives within 2 to 10 minutes, peaking around the 30- to 45-minute mark. Effects commonly sustain for 2 to 3 hours depending on tolerance and dose.
The initial phase features mental clarity and a mood lift, which many characterize as energized but controlled rather than racy. As the session progresses, body ease and muscle comfort become more prominent without heavy couchlock. This progression suits creative tasks, light socializing, or winding down in the evening.
Dosing influences the subjective curve. Low to moderate inhaled doses may emphasize focus and calm, while higher doses trend toward tranquil, introspective effects with increased appetite. Some users report mild dry mouth and dry eyes, which are common THC-related side effects.
The terpene blend likely modulates the tone of the experience. Limonene’s brightening properties can offset lethargy, while myrcene and caryophyllene support body comfort. Individuals sensitive to citrus-forward terpene stacks should start low to gauge personal response.
For edibles, onset ranges from 45 to 120 minutes with effects lasting 4 to 6 hours or longer. Because edible pharmacokinetics differ from inhalation, first-time users are advised to start at 2.5 to 5 milligrams THC and wait at least two hours before redosing. Most tolerance build-up occurs over repeated high-dose use, so spacing sessions helps maintain consistent effects.
Potential Medical Uses
Based on its reported cannabinoid and terpene profile, Auto Somachigun may offer utility for stress, mood, and mild to moderate pain concerns. THC in the mid to upper teens and low 20s, paired with caryophyllene and myrcene, can contribute to perceived analgesic and anxiolytic benefits in some users. Limonene’s association with mood elevation may support situational low mood or stress-related tension.
Patients with muscle tightness or exercise-related soreness might appreciate the balanced body relaxation without full sedation. Anecdotal reports include improved sleep latency at moderate evening doses, likely from cumulative myrcene and THC effects. Appetite stimulation is also common at higher doses, which may benefit those managing appetite suppression.
For anxiety-prone individuals, low-dose approaches are recommended to avoid THC-induced jitters. Starting with 1 to 2 inhalations or 2.5 to 5 milligrams THC orally, then titrating slowly, can help locate a comfortable therapeutic window. Combining THC with CBD from another source may smooth the response for sensitive users.
As with all cannabis products, potential side effects include dry mouth, dry eyes, transient tachycardia, and short-term memory impairment. Higher doses can increase dizziness or anxiety in susceptible individuals. Those with a personal or family history of psychotic disorders should consult a clinician and proceed cautiously.
Drug metabolism considerations apply because THC and many terpenes interact with cytochrome P450 enzymes, particularly CYP2C9 and CYP3A4. Individuals taking warfarin, certain antiepileptics, or other narrow-therapeutic-index medications should discuss cannabis use with a healthcare professional. Verified lab testing of each batch is essential for medical use to ensure accurate potency and contaminant safety.
Comprehensive Cultivation Guide
Auto Somachigun is designed for accessibility, making it a strong choice for first-time growers and efficient for experienced cultivators optimizing space. As an autoflower, it completes its life cycle under a constant light schedule, typically 18 hours on and 6 hours off. The average seed-to-harvest window is about 70 to 85 days, with some phenotypes finishing as early as day 65 and others extending to around day 90 in cooler rooms.
Germination and early seedling care are foundational. Paper towel, rapid rooters, or directly into the final pot all work; autos generally prefer starting in their finishing container to avoid transplant shock. Maintain 24 to 26 degrees Celsius, 65% to 70% relative humidity, and gentle light around 200 to 300 PPFD for the first 5 to 7 days.
Once established, move to 400 to 600 PPFD for vegetative growth while keeping RH near 60% and temperature at 24 to 27 degrees Celsius. By day 18 to 25, most plants show preflowers and begin stretch; increase PPFD to 600 to 900 for bloom, targeting a daily light integral around 35 to 45 mol per square meter per day. A light schedule of 18/6 or 20/4 balances energy efficiency and growth; the extra 2 hours on 20/4 can accelerate metabolism and reduce total days to harvest by several days for some phenotypes.
Substrate choice depends on experience and goals. In soil, use a lightly amended mix with good aeration, such as 30% perlite or pumice, to reduce overwatering risk. In coco coir, maintain a consistent feed schedule with 20% runoff and a pH of 5.8 to 6.0, while soil grows typically favor 6.2 to 6.8 pH.
Nutrient management should scale with growth stage. Autos generally need 10% to 20% less nitrogen than comparable photoperiods during bloom. Aim for electrical conductivity (EC) around 0.8 to 1.2 in early growth, 1.2 to 1.6 in mid-veg, and 1.6 to 1.8 in peak bloom, adjusting based on leaf color, tip burn, and runoff readings.
Calcium and magnesium are critical under high-intensity LEDs. Supplement with 100 to 150 ppm Ca and 50 to 75 ppm Mg if your base water is soft or if you see interveinal chlorosis. Maintain potassium availability during weeks 5 to 8 from sprout to support bulking and resin production without overdriving phosphorus.
Training strategies for autos should be gentle and early. Low stress training from day 10 to 25 can open the canopy, improving light penetration and increasing yield. Topping is optional and should be done only once, ideally between day 15 and 20, or avoided altogether if plants are slow to start; autos recover time is limited.
Environmental control drives consistency. Keep daytime temperatures at 24 to 28 degrees Celsius with nights 2 to 4 degrees lower. Track vapor pressure deficit around 0.9 to 1.1 kPa in early growth and 1.2 to 1.5 kPa in bloom to optimize gas exchange and terpene retention.
Watering practices should avoid extremes. In soil, allow the top 2 to 3 centimeters to dry before watering to field capacity; in coco, smaller, more frequent feeds prevent salt spikes. Overwatering seedlings is a common error that slows autos during their critical early window.
Pest and disease prevention is best done proactively. Sticky traps and yellow cards help monitor fungus gnats and thrips, while biologicals like Bacillus thuringiensis israelensis and predatory mites can keep populations in check. Maintain good airflow with at least one oscillating fan per square meter and a HEPA intake filter if possible to reduce powdery mildew risk.
Flower development accelerates around day 35 to 45 from sprout. Reduce excessive nitrogen, support with adequate potassium and micronutrients, and keep relative humidity around 50% to 55% to minimize botrytis risk in dense flowers. Many growers add a mild carbohydrate source late bloom, though its effect is often indirect by supporting microbial activity in living soils.
Yield expectations depend on light, genetics, and grower skill. Under 600 to 900 PPFD and a steady 18/6 schedule, indoor yields of 350 to 500 grams per square meter are commonly reported, with single-plant harvests of 50 to 120 grams achievable in 10- to 15-liter containers. Outdoor container grows in warm climates typically produce 40 to 150 grams per plant depending on season length and sunlight.
Harvest timing should be guided by trichome maturity. Many growers target mostly cloudy trichomes with 5% to 15% amber for a balanced effect, often occurring around day 70 to 80. Flushing practices vary; in inert media, a 7- to 10-day plain water period can reduce residual salts, while living soil growers often maintain light feeding to sustain microbial health.
Drying and curing are critical to preserve Auto Somachigun’s fruit-forward aromatics. Aim for 10 to 14 days at 18 to 20 degrees Celsius and 58% to 62% relative humidity, then cure in airtight jars at 60% RH for at least two weeks. Use digital hygrometers in each jar and burp daily for the first week to prevent moisture pockets.
Space planning matters in small tents. A 60-by-60-centimeter tent can accommodate one to two plants in 11- to 15-liter pots with adequate airflow; a 120-by-120-centimeter tent handles four to six plants comfortably. Keep the canopy even with LST tie-downs and leaf tucking to maximize light distribution.
For hydroponic growers, deep water culture or recirculating systems can accelerate vegetative growth. Maintain dissolved oxygen above 7 milligrams per liter and water temperatures around 18 to 20 degrees Celsius to avoid root pathogens. EC targets are similar to coco, but plants may uptake faster and require vigilant monitoring.
If odor control is a concern, a properly sized carbon filter matched to fan CFM is essential. Fruit-forward terpene stacks can be noticeable during late bloom, and a 20% oversize on filtration helps maintain negative pressure. Inspect duct runs for leaks and replace pre-filters as they load with dust.
Overall, Auto Somachigun rewards consistency more than intervention. Keep inputs steady, avoid heavy-handed pruning late, and maintain stable climate parameters. The result is a compact, resin-rich harvest showcasing the strain’s balanced chemistry and lively flavor profile.
