Auto AK-47 XL is a modern autoflowering interpretation of the classic AK-47 lineage, created by Divine Seeds to deliver bigger plants and heavier harvests in a compact, fast-finishing format. AK-47 itself emerged in the 1990s and went on to win more than a dozen major cannabis awards, earning a reputation for consistent potency and a balanced, crowd-pleasing effect profile. By integrating ruderalis genetics to fix the day-neutral flowering trait, Divine Seeds made the line accessible to growers who want speed, simplicity, and reliability without sacrificing resin quality.
The XL designation signals an emphasis on plant size, lateral branching, and cola density compared to many first-generation autoflowers. Early auto versions of flagship photoperiod strains often traded yield and terpene depth for speed; Auto AK-47 XL was selected to reverse that compromise. Breeding for XL vigor typically involves multi-generational selection, favoring phenotypes that maintain the original AK-47 flavor and psychoactive character while pushing biomass and resin output upward.
Divine Seeds is known for robust, climate-resilient autos that perform in short-season regions, and Auto AK-47 XL reflects that mandate. The cultivar was stabilized across successive filial generations to improve uniformity in height, internodal spacing, and flowering time. While phenotypic variation still exists, reports from experienced cultivators often describe a narrow range of finish times and similar aroma signatures across plants.
In practical terms, the shift from photoperiod AK-47 to an XL auto means most growers can plan for a seed-to-harvest window of roughly 70 to 85 days under 18 to 20 hours of daily light. That puts it squarely in the high-velocity category for personal and micro-commercial gardens. For regions with limited summers or unpredictable weather, two or even three staggered runs are feasible in a single outdoor season, a production pattern that was impossible with traditional photoperiod schedules.
The success of Auto AK-47 XL also reflects broader improvements in modern autoflower breeding. Over the last decade, average THC levels in autos have climbed notably, with many lines now routinely testing in the high teens to low twenties. Auto AK-47 XL belongs to this new wave, combining respectable potency with a recognizable AK-47 aroma that leans spicy, woody, and subtly sweet.
Genetic Lineage and Heritage
Divine Seeds lists the heritage as ruderalis, indica, and sativa, echoing the three-way genetic architecture that underpins most contemporary autoflowers. The sativa influence in the AK-47 family traditionally derives from tropical landrace inputs such as Colombian and Thai, which tend to impart a bright, cerebral lift and complex floral-citrus accents. The indica backbone typically traces to Afghan lines, providing density, resin thickness, and a steady body relaxation.
Ruderalis genetics contribute the day-neutral flowering trait that defines all autoflowers. Unlike photoperiod strains that require a 12-hour dark period to trigger bloom, ruderalis-derived plants flower based on age and developmental cues. This trait allows Auto AK-47 XL to flower reliably under long days, making 18 to 20 hours of light per day a common cultivation strategy for maximizing growth and yield.
Because ruderalis plants evolved in harsher northern climates, they tend to pass on hardiness to their hybrids. In practice, this can mean better tolerance for cool nights, shorter photoperiod sensitivity, and a willingness to finish the life cycle even as temperatures fluctuate. That resilience is part of why autos like Auto AK-47 XL are popular in latitudes where photoperiod cannabis struggles to finish before autumn rains.
Phenotypically, Auto AK-47 XL leans hybrid, often showing medium internodes, moderate leaf size, and a structure that supports multiple primary tops. Compared to some compact autos, XL phenotypes push a bit taller and wider, especially when provided abundant light and root volume. This physical expression mirrors its genetic balance, delivering both airy canopy reach and dense, resinous flowers that reflect the indica side.
Growers can expect three broad phenotype tendencies within a stable seed lot. One will be slightly taller with a bit more sativa architecture and nuanced citrus-floral terpene accents. Another will be more compact and indica-forward, with shorter internodes and heavier spice-wood aromas; a middle phenotype typically blends traits from both ends while offering the best balance of yield and ease of training.
Appearance and Plant Morphology
Auto AK-47 XL plants frequently reach 70 to 120 cm indoors and 90 to 140 cm outdoors, depending on pot size, light intensity, and feeding intensity. The XL selection favors a sturdy central stem with 6 to 10 strong laterals that can form a crown of main colas under simple low-stress training. Internodal spacing runs moderate, allowing light to penetrate while still stacking calyxes densely.
Leaves start medium-green, broad-lobed at first, then narrow modestly as the plant transitions into bloom. In late flower, fans can display subtle lime and gold hues, especially under lower nitrogen regimens, while sugar leaves frost heavily. A healthy specimen displays a high calyx-to-leaf ratio, making manicuring relatively efficient compared to leafier autos.
Mature flowers are chunky, conical, and resin-sheathed, with pistils that shift from cream to deep orange as harvest nears. Trichome heads are often large and plentiful, contributing to a silvery sheen that photographs well and preserves well during slow cures. Under magnification, glandular heads show a dense field of capitate-stalked trichomes, a visual correlate to the strain’s extraction suitability.
In dialed-in indoor conditions with 600 to 900 micromoles per square meter per second of PPFD and a daily light integral of 35 to 45 mol per square meter, yields of 450 to 600 g per square meter are realistic for experienced growers. Outdoors, single plants in 20 to 40 liter containers typically produce 90 to 200 g, with top-end plants exceeding that range in optimal sun and soil. These figures assume consistent nutrition, adequate airflow, and strict pest management.
Branch pliability makes Auto AK-47 XL receptive to gentle tie-downs and canopy shaping. The cultivar responds best to low-stress techniques during the first three to four weeks of growth, when its structural blueprint is set. Later, as flowers bulk rapidly, staking or soft netting helps support cola weight and prevents lodging under heavy resin load.
Aroma and Bouquet
The bouquet of Auto AK-47 XL blends classic AK spice and wood with fresh citrus and sweet herbal undertones. Early vegetative aromas lean green and slightly peppery; as preflower sets, notes of cedar and black pepper grow more defined. During peak bloom, the nose deepens into a layered mix of warm spice, dried herbs, and subtle floral-citrus top notes.
When flowers are lightly squeezed, many growers report a flash of sweet, almost honeyed herbal tone riding atop a crisp pine snap. On the grind, the profile turns louder and more complex, adding hints of sour orange zest and a faint earthy musk. The presence of caryophyllene and humulene helps explain the pepper-wood axis, while limonene and pinene reinforce the bright, clean edges.
Post-cure, the aromatic balance tightens and clarifies if the dry and cure were slow and cool. At 60 percent relative humidity and around 60 degrees Fahrenheit during drying, more volatile monoterpenes are better preserved, resulting in a nose that feels both vivid and rounded. Total terpene content in well-grown samples commonly falls between 1.2 and 2.2 percent by weight, with cultivar expression and cultivation practices driving variation.
Some phenotypes lean slightly skunky, a quality associated with volatile sulfur compounds present at parts-per-billion concentrations. These thiol-driven notes can pop briefly and then recede behind the dominant spice-wood character. Proper storage in airtight glass at stable temperatures helps retain these fleeting top notes for months.
Flavor and Mouthfeel
Auto AK-47 XL translates its aroma into a coherent, flavorful smoke or vapor with a balanced sweet-spice character. On the inhale, expect a clean pine and citrus snap that quickly rounds into pepper and cedar. The exhale tends to carry a sweet herbal finish, sometimes with a faint tea-like dryness that lingers on the palate.
Vaporization at 175 to 190 degrees Celsius emphasizes limonene and pinene brightness, often yielding a zesty, uplifting taste in the first draws. As the session warms into the 195 to 205 degree range, deeper myrcene and caryophyllene notes emerge, bringing the pepper and wood tones into sharper focus. Combustion yields a fuller, toastier spice, and benefits from a thorough cure to smooth the edges.
Mouthfeel is medium-bodied and resinous without being harsh when properly dried to a target water activity of 0.58 to 0.62. Over-dry flowers can taste sharp and papery, while over-wet cures blur flavor definition and risk microbial growth. A two- to four-week cure with periodic burping consolidates flavor into a unified profile and noticeably improves smoothness.
Users who are sensitive to peppery terpenes may prefer slightly lower vapor temperatures to emphasize sweet and citrus tones. Conversely, those seeking the spicier, grounding qualities can step temperatures up in stages across a session. In mixed sessions, the flavor arc often begins bright and ends warm and woody, mirroring the underlying terpene volatility spectrum.
Cannabinoid Profile and Potency
Auto AK-47 XL typically expresses high THC with low CBD in most phenotypes, a profile mirroring the original AK-47 family. Growers commonly report THC in the 17 to 22 percent range, with standout plants reaching the low 20s under ideal conditions. CBD is usually minimal, often around 0.1 to 0.8 percent, while minor cannabinoids such as CBG can present in the 0.2 to 1.0 percent band.
The felt potency of a given sample depends on more than headline THC. Total terpene content, terpene composition, and how well the flower was dried and cured can shift subjective intensity quite a bit. A well-cured sample at 19 percent THC and 2 percent terpenes can feel more potent than a poorly cured sample at 22 percent THC and 0.6 percent terpenes.
From a dosing standpoint, 20 percent THC flower contains roughly 200 mg THC per gram before combustion or vaporization losses. A 0.33 g joint would therefore hold about 66 mg THC; with inhalation bioavailability ranging widely from roughly 10 to 35 percent, the delivered dose might land between 7 and 23 mg. Newer consumers often find 2 to 5 mg delivered to be a comfortable starting range for inhaled sessions, while experienced users may aim higher.
For infusions, decarboxylation efficiency matters. THCA converts to THC with a mass loss factor of roughly 0.877 during decarb, and common home methods at 105 to 115 degrees Celsius for 30 to 45 minutes can achieve high conversion rates. Accurately calculating infusion potency requires tracking input weight, lab potency if available, decarb efficiency, and oil absorption losses, which can range from 10 to 20 percent depending on technique.
Terpene Profile and Chemistry
Auto AK-47 XL tends to show a balanced terpene profile led by beta-caryophyllene, myrcene, and either alpha-pinene or limonene depending on phenotype. In many harvests, total terpenes cluster around 1.2 to 2.2 percent by weight with top terpenes each contributing roughly 0.2 to 0.7 percent. Secondary contributors such as humulene, ocimene, and linalool appear in smaller amounts, often in the 0.05 to 0.3 percent range.
Beta-caryophyllene, a sesquiterpene with a robust pepper-wood aroma, is a known CB2 receptor agonist in preclinical research, aligning with user reports of soothing, body-focused effects. Myrcene contributes earthy-herbal tones and is associated with muscle relaxation and sedation at higher exposure levels. Alpha-pinene brings a crisp pine note and has been linked to alertness and potential support for memory retention in animal and in vitro studies.
Limonene imparts a bright citrus snap and correlates with mood-elevating, stress-easing impressions in human self-reports. Humulene, structurally related to caryophyllene, layers a dry, woody bitterness sometimes described as hoppy or balsamic. Trace linalool can add a gentle lavender sweetness and may contribute to anxiolytic effects when present alongside caryophyllene and myrcene.
The precise terpene hierarchy varies with environment, nutrition, and harvest timing. Cooler late-flower nights and careful curing often preserve more monoterpenes like pinene and limonene, increasing perceived brightness. Warmer or extended cures can tilt the flavor toward deeper, spicier sesquiterpenes, subtly shifting the experience from zesty to grounding.
Experiential Effects and Use Cases
Consumers commonly describe Auto AK-47 XL as a balanced hybrid experience that blends an upbeat headspace with steady body relief. The first 5 to 10 minutes after inhalation often bring clear euphoria, sociability, and a slight sharpening of focus. As the session settles, a warm relaxation spreads through the shoulders and neck without immediate couchlock at moderate doses.
This mix makes the strain suitable for daytime or late-afternoon use, especially for creative tasks, light exercise, or social time. Many users find it pairs well with music, brainstorming, or meal prep, where uplift and coordination both matter. At higher doses or later-harvested, amber-rich batches, the body effect grows heavier and can become more sedating toward the tail end of the experience.
Typical duration runs 2 to 3 hours for inhaled consumption, with a defined peak from about 20 to 45 minutes. Vaporization tends to produce a slightly cleaner, more head-forward arc at first, while combustion can feel fuller and heavier due to broader pyrolytic byproducts. Individuals sensitive to anxiety should start low and increase slowly, as high-THC strains can induce racing thoughts in some users.
Common side effects mirror those of other potent hybrids. Dry mouth and dry eyes are reported by a large share of users, often in the 30 to 60 percent range depending on dose and hydration status. Transient increases in heart rate can occur, particularly at higher doses, and generally resolve within the first hour as the experience stabilizes.
Potential Medical Applications
Auto AK-47 XL’s chemistry suggests a range of potential symptom-management roles for adults in legal jurisdictions. The combination of moderate-to-high THC, caryophyllene, and myrcene may support relief from musculoskeletal pain, stress, and low mood. In observational studies of inhaled cannabis, many participants report 20 to 30 percent reductions in perceived pain intensity within an hour, though individual responses vary widely.
For anxiety-prone patients, the presence of pinene and limonene may provide a counterbalance to THC’s excitatory tendencies at modest doses. Pinene has been studied for potential benefits to alertness and may mitigate memory deficits sometimes associated with THC. Limonene is linked to mood elevation in preclinical and human fragrance research, adding a bright, easeful edge to the effect profile.
Sleep applications may hinge on harvest timing and dose. Flowers harvested with a higher proportion of amber trichomes and cured to emphasize myrcene and caryophyllene often feel more body-heavy, supporting sleep onset for some. In contrast, early-harvest, pinene-forward expressions may be better suited for daytime stress relief without excessive sedation.
Other potential uses include appetite stimulation, nausea modulation, and relief of tension headaches in select individuals. Humulene’s appetite-dampening reputation suggests that not every phenotype will boost appetite equally, and patients seeking that effect might prefer limonene-forward samples. As with all cannabis-based self-care, titration is key; many medical users find 2.5 to 5 mg delivered THC a pragmatic starting dose for inhaled sessions, increasing in small increments as needed.
Cannabis can interact with medications metabolized by CYP2C9, CYP2C19, and CYP3A4, among others. Individuals with cardiovascular disease, a history of psychosis, or who are pregnant or breastfeeding should consult medical professionals before use.

Comprehensive Cultivation Guide
Auto AK-47 XL was bred by Divine Seeds as a ruderalis-indica-sativa hybrid designed for speed and yield, and it responds predictably when environmental basics are dialed in. Most growers can expect 70 to 85 days from sprout to harvest, with earlier phenotypes finishing nearer to day 70 and larger, XL-leaning plants pushing past day 80. Planning around that window, especially for nutrient tapering and harvest scheduling, pays dividends in quality and yield.
Germination and Seedling Stage. Aim for 24 to 26 degrees Celsius and 70 to 75 percent relative humidity for rapid emergence within 24 to 72 hours. Many cultivators place sprouted seeds directly into their final container to avoid transplant stress, especially with autos that have limited time to recover from root disturbance. Use a light, aerated medium with an initial EC of 0.4 to 0.6 and pH of 6.2 to 6.5 in soil or 5.8 to 6.2 in soilless, and provide gentle light at 200 to 300 micromoles PPFD for 18 to 20 hours per day.
Vegetative Growth in an Autoflower Context. Autos do not have a distinct veg stage, but the first 3 to 4 weeks are functionally vegetative while the plant builds frame and then initiates bloom. Increase light intensity to 400 to 600 micromoles PPFD by the end of week two and 600 to 800 by the start of week four. Maintain VPD around 0.8 to 1.1 kPa, translating to roughly 24 to 27 degrees Celsius and 60 to 65 percent relative humidity.
Nutrition and Irrigation. Start at EC 0.6 to 0.8 in week one, ramping to 1.2 to 1.6 by week three as the plant demands more nitrogen, calcium, and magnesium. As early flowers form, transition to an EC of 1.6 to 1.9 with a balanced bloom formula that still includes adequate nitrogen to avoid premature yellowing. In the last two weeks, many growers taper down to EC 0.6 to 0.8 with plain water or a very light solution to improve burn and flavor, particularly for salt-based regimens.
pH, Water, and Media. In soil, maintain pH 6.2 to 6.8; in coco or hydro, 5.8 to 6.2. Keep irrigation water between 18 and 22 degrees Celsius to protect root function and dissolved oxygen levels. For coco, target 10 to 20 percent runoff per feed to prevent salt buildup; check runoff EC periodically and adjust feeding strength accordingly.
Lighting Strategy. Auto AK-47 XL responds well to 18 hours on and 6 hours off from start to finish, balancing vigor and efficiency. Some growers run 20 on and 4 off for maximum growth, especially under lower-intensity fixtures, accepting a modest increase in electricity use. Target PPFD of 600 to 900 in mid to late bloom for most LED gardens; under CO2 enrichment around 1,000 to 1,200 ppm, PPFD can be pushed toward 1,000 to 1,100 if other conditions are optimal.
Container Size and Rooting. Use 11 to 19 liter pots indoors for a strong XL expression, or 20 to 40 liter containers outdoors where root temperatures fluctuate more. Fabric pots enhance oxygenation and can accelerate early growth, though they dry faster and require attentive irrigation. Avoid multiple transplants; if you must up-pot, do it once by day 10 to 14 at the latest to minimize growth stalls.
Training and Canopy Management. Low-stress training starting around day 14 to 18 works best, gently tying the main stem to open the canopy and encourage multiple tops. Screen of Green can be done lightly if the screen is in place by week two, but heavy scrogging or late training risks slowing autos that are already transitioning to bloom. Topping is possible on very vigorous individuals around node four before day 18 to 20, but many growers skip topping in favor of bend-and-tie methods that carry less risk.
Environmental Control and VPD. Maintain day temperatures of 24 to 28 degrees Celsius and night temperatures of 18 to 22 to promote steady metabolism without stretching. Relative humidity should track roughly 60 to 70 percent for seedlings, 50 to 60 percent for early growth, 45 to 55 percent for early bloom, and 40 to 45 percent for late bloom. VPD in the 0.9 to 1.2 kPa range generally keeps leaf transpiration and nutrient flow in balance throughout.
Integrated Pest Management. Begin with prevention: clean rooms, intake filtration, and quarantining any incoming plant material. Use beneficial insects like Amblyseius cucumeris against thrips and Phytoseiulus persimilis against spider mites if pressure appears, and maintain weekly inspections under leaf surfaces. Biologicals such as Bacillus subtilis and Bacillus amyloliquefaciens can help suppress powdery mildew and botrytis, especially in humid geographies.
Outdoor Considerations. Autos allow multiple harvests per season in many climates, and Auto AK-47 XL’s resilience makes it a strong candidate for shoulder-season runs. In temperate zones, a late spring sowing followed by a midsummer sowing can deliver two crops before autumn rains. Position plants for 8 or more hours of direct sun, protect from prevailing winds, and consider rain covers during late bloom to prevent botrytis on the dense XL colas.
Deficiency and Excess Diagnostics. Pale new growth and interveinal chlorosis often indicate magnesium deficiency, especially in coco; supplement with magnesium sulfate or a cal-mag product and bring pH into the ideal range. Dark, clawed leaves point to nitrogen excess; reduce N and increase runoff to clear salts. Potassium deficiency in mid-bloom manifests as marginal leaf burn and weak stems; adjust bloom K, but avoid overshooting and raising EC beyond the plant’s tolerance.
Yield Expectations and Plant Density. Indoors, a sea-of-green approach at 9 to 12 plants per square meter in 11 liter pots can produce quick, uniform canopies. Single-plant showcases in 19 liter pots with careful training can yield equally well if the light footprint is even. Under LEDs delivering 35 to 45 mol per square meter per day of DLI, experienced growers routinely hit 450 to 600 g per square meter with Auto AK-47 XL; outdoors, 90 to 200 g per plant is common with good sun.
Harvest Timing. Monitor trichomes with a jeweler’s loupe or microscope; a balanced effect often coincides with mostly cloudy heads and 5 to 10 percent amber. For a heavier, sleep-oriented effect, allow 15 to 25 percent amber before cutting. Pistil color can mislead; rely on trichomes and overall plant cues like slowed water uptake and minimal new white pistils.
Flush, Dry, and Cure. If feeding mineral salts, many growers flush 7 to 10 days with plain water to reduce residual nutrient sap. Dry in the dark at roughly 60 degrees Fahrenheit and 60 percent relative humidity for 10 to 14 days until small stems snap cleanly. Cure in airtight glass at 62 percent humidity, burping daily for the first week and weekly thereafter, targeting a stable water activity of 0.58 to 0.62.
Extraction and Processing. Auto AK-47 XL’s resin coverage lends itself to solventless methods; hand-washing bubble hash pulled through 90 to 120 micron bags and pressed at 90 to 100 degrees Celsius often yields 15 to 22 percent rosin from high-grade material. Hydrocarbon extraction can capture the bright top notes, but post-processing choices like low-temp purging and terpene reintroduction shape the final profile. For edibles, decarb thoroughly and homogenize infusions to ensure consistent dosing across servings.
Quality, Consistency, and Scaling. Keep detailed logs of EC, pH, PPFD, VPD, and runoff metrics; small corrections early often prevent yield loss later. Auto cultivars reward consistency more than heroics; stable conditions and gentle, early training do more for XL autos than heavy intervention. With these fundamentals in place, Auto AK-47 XL performs as advertised, delivering fast, high-quality harvests with the signature spice-wood character that made the AK family a classic.
