AK 47 by Bulk Seeds: A Comprehensive Strain Guide

Introduction

AK-47 by Bulk Seeds is a sativa-leaning hybrid that has earned enduring respect for its balance of uplifting clarity and full-bodied satisfaction. Known colloquially as a "one-hit wonder" in some circles, it typically pairs a bright, cerebral onset with a smooth, grounded finish. Growers and consumers value its reliability: stable structure, strong terpene output, and consistently moderate-to-high potency.

Across the global market, AK-47 has remained relevant for decades because it performs predictably in gardens and delivers a recognizable, layered flavor profile. In most contemporary lab results and marketplace reports, AK-47 tests in the high-teens to low-20s for THC, with CBD typically below 1%. Its terpene blueprint commonly showcases myrcene alongside supporting levels of pinene and caryophyllene, yielding aromas of earth, spice, pine, and sweet florals.

The Bulk Seeds selection continues this lineage with a mostly sativa heritage tuned for vigor, quality resin coverage, and efficient flowering times. Whether grown indoors under controlled conditions or outdoors in warm, sunny climates, AK-47 rewards attentive cultivators with generous harvests. Its ease of growth and user-friendly effects profile have helped the strain become a core reference point for modern hybrids and numerous offspring crosses.

History and Cultural Impact

AK-47’s legacy stretches back to the early era of modern hybridization, when breeders began recombining landrace sativas and sturdy Afghan indicas to find optimal balances. Over time, this blend became a go-to cultivar for enthusiasts seeking a cerebral high that does not tip into jitters. Bulk Seeds’ AK-47 maintains the spirit of this classic while presenting a selection designed for consistent garden performance.

In retail and medical markets, AK-47 routinely appears among top sellers because it feels familiar, effective, and versatile. Leafly has consistently included AK-47 in editorial lists of historically significant strains, and it appears in Leafly’s list of the 100 best weed strains of all time. This ongoing cultural relevance correlates with widespread availability of photoperiod, fast, and autoflower variants, making it accessible to growers at every skill level.

Online consumer feedback over the years emphasizes its sociable, upbeat headspace and manageable physical relaxation. Leafly notes that AK-47 may deliver a steady and long-lasting cerebral buzz that keeps users mentally alert and engaged. That dependable experience helped cement it as a staple in home grow tents and dispensaries alike, while its genetic footprint can be found in many successful crosses today.

Genetic Lineage and Breeding Story

While the precise genealogy can vary by breeder, AK-47 is generally understood as a cross of multiple regional sativa lines (often reported as Colombian, Mexican, and Thai) with a stabilizing Afghani indica component. This combination yields a mostly sativa heritage, aligning with the context details provided for the Bulk Seeds line. The result is a genotype that stacks quick-onset mental clarity atop a body-friendly base reminiscent of Afghan resin plants.

Bulk Seeds’ AK-47 reflects careful selection for uniformity, terpene output, and flower structure. Their sativa-forward selection maintains the brisk mental energy attributed to Latin American and Southeast Asian ancillaries while preserving the Afghan’s density and resin production. Over many generations, breeding efforts have aligned the phenotype around mid-height plants, admirable colas, and readily extractable resin for both flower and concentrate use.

The genetic influence of AK-47 has propagated extensively. Examples include Kali 47 (Kali Mist x AK-47), which Leafly notes may help relieve depression, pain, and stress, and Amnesia x AK-47, a hybrid offered by seed vendors for growers seeking an energetic, citrus-tilted profile. This expansive family tree underscores AK-47’s role as a foundational parent in modern hybrid projects.

Appearance and Morphology

Bulk Seeds’ AK-47 typically exhibits medium stature with strong lateral branching and a central cola that can stack into a long spear under high-intensity lighting. Plants often stretch 1.5–2.0x after the flip to 12/12, ending in the 80–120 cm range indoors if vegged for 4–5 weeks. Internodes are moderate, allowing for efficient canopy training without uncontrollable vertical surge.

Flowers present as dense, elongated buds with a lime to olive-green base tone, frequently accented by vibrant orange pistils. The calyxes are moderately swollen, with a resin blanket that becomes visibly frosty by week 6–7 of bloom under dialed-in conditions. Mature colas can be thick, making airflow and humidity management important late in flower to prevent botrytis.

Trichome coverage is a highlight, making AK-47 attractive for dry-sift, ice water hash, and hydrocarbon extraction. Sugar leaves tend to remain relatively narrow for a hybrid, nodding to the sativa heritage while preserving mechanical trim efficiency. Overall bag appeal is high, thanks to both resin density and the strain’s tendency to finish with a photogenic, crystalline sheen.

Aroma

AK-47’s aromatic profile is robust and layered, commonly opening with notes of earth and sweet florals. Subtle pine and cedar-like woodiness often rise in the background, accompanied by peppery spice. Many phenotypes also display a mild citrus or sour tang that brightens the bouquet.

The combination of myrcene with pinene and caryophyllene helps explain its bouquet complexity. Myrcene can lend earthy, musky sweetness, while pinene contributes pine forest freshness and caryophyllene adds freshly cracked pepper. Together, these terpenes translate into a nose that is both classic and memorable, often described as “old-school with a modern twist.”

Expect the aroma to intensify significantly during the final 2–3 weeks of flowering. Growers frequently install carbon filtration because the scent can project beyond grow rooms at peak terpene production. When properly cured, AK-47 retains a gorgeous room-filling perfume that rewards patient curing and airtight storage.

Flavor

On the palate, AK-47 leans toward a smooth, earthy profile with sweet, floral edges and a light citrus snap. The piney quality threads through the mid-palate, adding a fresh, resinous lift that balances the sweetness. Peppery spice from caryophyllene typically emerges on the exhale, leaving a warming, mouth-coating finish.

Vaporizing at lower temperatures (175–185°C) can highlight the sweet floral and citrus facets, emphasizing myrcene’s fruit-adjacent roundness and pinene’s brisk lift. Combustion or higher-temp vaping accentuates the spicy, woody tones and can increase perceived potency. Many consumers report that AK-47’s flavor holds up beyond the first few draws, a testament to its terpene density.

When cured to 62% relative humidity and burped for 3–6 weeks, the flavor deepens and becomes more cohesive. Monoterpenes remain vivid, while sesquiterpenes contribute to a long, complex finish. Solid curing practices are particularly rewarding for this strain, unlocking nuanced sweet-herbal layers.

Cannabinoid Profile

Modern market data and lab reports commonly place AK-47’s THC between 17% and 22%, with averages clustered around 18–20% in many retail regions. Select phenotypes and optimized grows may surpass 22%, but most consumer lots gravitate toward the high-teens. CBD content is usually low, often measuring 0.1–0.7%, making this a THC-forward cultivar.

Minor cannabinoids can contribute subtle modulation of effects. CBG frequently appears in the 0.1–1.0% range, while CBC and THCV show up sporadically at trace levels, depending on phenotype and cultivation variables. While these minor constituents are low, their entourage effects may still influence the strain’s clear-headed, sustained buzz.

For medical users sensitive to THC, AK-47’s potency warrants a measured approach. Starting with low doses (e.g., 2.5–5 mg THC in edibles or 1–2 small inhalations) allows evaluation of tolerance before scaling. Consumers seeking a gentler ride sometimes blend AK-47 with a CBD-dominant cultivar to bring the THC:CBD ratio closer to 2:1 or 1:1.

Terpene Profile

Leafly’s editorial insights on classic strains note that AK-47 has a terpene profile rich in pinene and caryophyllene, which helps explain its alert, focused sensation without overstimulation. At the same time, Leafly’s Top 100 strains list identifies myrcene as a dominant terpene for AK-47 in many analyses. The practical takeaway is that AK-47 commonly expresses a myrcene-forward profile, with pinene and caryophyllene frequently co-dominant or prominent.

Typical ranges observed in commercial tests show myrcene often between 0.4–1.0% by dry weight, pinene (alpha and beta combined) around 0.2–0.6%, and caryophyllene near 0.2–0.5%. Limonene often appears in the 0.15–0.4% zone, contributing a light citrus snap, while humulene and linalool can register in trace-to-moderate amounts. These numbers vary by phenotype, cultivation style, and harvest timing, but they illustrate a consistent aromatic theme.

Because pinene and caryophyllene can modulate the feel of THC, many consumers describe AK-47 as clear yet grounded. Pinene is often associated with alertness and bronchodilation in preclinical literature, while caryophyllene, a CB2 agonist, is studied for anti-inflammatory potential. In AK-47, these two often complement myrcene’s calming base, resulting in a balanced, confidently functional profile.

Experiential Effects

AK-47 is renowned for a steady, long-lasting cerebral buzz that keeps users mentally alert and engaged, in line with Leafly’s strain description. The onset is usually swift, with a palpable lift in mood and focus within the first few minutes of inhalation. Rather than a jittery or racy headspace, the experience tends to feel purposeful and upbeat, particularly when consumed in moderate amounts.

As the session unfolds, the Afghani influence contributes a body ease that smooths out the edges without steering into sedation. This effect pairing—mentally bright and physically comfortable—makes AK-47 a favorite for daytime creative work, socializing, or hobby time. Many users report enhanced conversation, musical appreciation, and task flow.

Side effects follow the typical THC pattern: dry mouth, dry eyes, and occasional anxiety if dosing too high. Sensitive users can reduce risk by starting low and favoring vaporization at moderate temperatures, which may feel cleaner and less overwhelming. When dosage is respected, AK-47’s clear-headed lineage tends to produce a positive, controllable arc of effects that tapers gently over 2–3 hours for inhalation and 4–6 hours for edibles.

Potential Medical Uses

Patient anecdotes and marketplace feedback suggest that AK-47 may support relief for stress, low mood, and mental fatigue. Its alert-yet-calm character can be helpful for users who want to lift mood without a crash, especially in the afternoon. The presence of pinene and caryophyllene alongside myrcene may contribute to this focused calm by balancing stimulation with body-level ease.

Mild-to-moderate pain relief is commonly reported, notably for tension headaches, neck and shoulder tightness, and general musculoskeletal aches. The anti-inflammatory properties under study for caryophyllene may partially account for these experiences, though clinical confirmation is still developing. Some users also report relief for appetite loss and nausea, as THC and certain terpenes can increase interest in food and settle the stomach.

For anxiety-prone patients, pacing is crucial. Low doses can feel centering, while high doses may amplify unease; titration is advised to locate the personal therapeutic window. As with any cannabis regimen, patients should discuss consumption with a healthcare professional, particularly if they take medications or manage chronic conditions.

Comprehensive Cultivation Guide: Environment and Setup

AK-47 by Bulk Seeds is approachable for first-time gardeners yet scalable for advanced growers seeking top-shelf resin. Indoors, maintain daytime temperatures of 22–26°C and nighttime 18–22°C for best vigor. Target relative humidity of 60–70% in veg, transitioning to 55–60% in early bloom, 45–50% mid bloom, and 40–45% in the final two weeks.

Lighting at 600–900 µmol/m²/s PPFD in veg and 900–1,200 µmol/m²/s in bloom can drive dense flowers without excessive stretch. Under LEDs, ensure adequate calcium and magnesium supplementation and maintain leaf surface temperatures 1–2°C lower than HPS environments. For hydro and coco systems, start with EC 1.2–1.4 in late veg and climb to EC 1.8–2.2 in peak bloom, monitoring runoff to avoid salt buildup.

Airflow is essential because AK-47 can form thick colas. Deploy oscillating fans above and below the canopy and maintain a slight negative pressure in the room with carbon filtration to control odor. A fresh air exchange rate of 20–30 air changes per hour for small tents helps regulate heat and humidity and keep pathogens at bay.

Comprehensive Cultivation Guide: Propagation and Vegetative Growth

Germinate seeds using the paper towel or direct-into-cube method at 24–26°C with near-saturated humidity (90–100%). Most viable seeds will pop within 24–72 hours; plant sprouts when the taproot is 0.5–1.5 cm to avoid breakage. Keep the medium evenly moist but never waterlogged to protect young roots.

In soil, aim for a pH of 6.2–6.8; in coco or hydro, 5.8–6.2. Early vegetative feeding can be light (EC 0.8–1.1), increasing gradually as plants develop 5–7 nodes. AK-47 responds well to 18/6 or 20/4 light cycles in veg, and a 4–5 week veg period usually produces sturdy frames without excessive bushiness.

Because the strain stretches moderately, controlling vegetative height sets up a manageable bloom. Transplant to final containers 7–10 days before flip to 12/12 to ensure roots colonize the medium before rapid flowering. Consider starting in 1 L pots, stepping to 3–5 L, then finishing in 11–20 L (soil) or 7–12 L (coco) depending on plant count and training style.

Comprehensive Cultivation Guide: Training and Canopy Management

AK-47’s architecture favors topping, low-stress training (LST), and screen of green (ScrOG) techniques. Top at the 4th–5th node, train outward, and establish 6–10 main sites for balanced colas. In ScrOG, weave branches during the first 2 weeks after flip to maintain an even canopy and maximize light penetration.

Light defoliation helps expose bud sites and improve airflow, but avoid over-stripping, especially on sativa-leaning phenotypes that rely on leaf area for energy. A good cadence is a light leaf clean-up just before flip and a second, selective defoliation around day 21 of bloom. Lollipopping lower growth that won’t reach the light can redirect resources to top colas, improving yield density.

Expect 1.5–2.0x stretch in the first three weeks of bloom. Maintain 30–45 cm between canopy and LED fixtures depending on fixture intensity to minimize light stress. A stable canopy with multiple evenly developed sites is a proven route to high-yield, high-quality AK-47 harvests.

Comprehensive Cultivation Guide: Flowering, Nutrition, and Finishing

Flowering time for AK-47 typically lands at 8–9 weeks indoors (56–63 days), aligning with classic descriptions. Many growers harvest around day 60 when trichomes are mostly cloudy with 5–10% amber, preserving the strain’s signature clarity. Phenotypes with denser Afghan influence may prefer the full 9 weeks for optimal resin maturity.

During bloom, increase phosphorus and potassium while maintaining adequate calcium and magnesium, especially under LED lighting. A mid-bloom EC of 1.6–1.9 rising to 1.8–2.2 in weeks 6–7 works well, followed by a 7–10 day taper and final water-only period to improve burn and flavor. Maintain pH stability—6.0–6.3 in coco/hydro and 6.3–6.7 in soil—to support consistent nutrient uptake.

Indoors, yields of 400–550 g/m² are realistic under 600–1000 W-equivalent LED or HPS with good training and environment. Outdoors, single plants can exceed 500–700 g under full sun and generous root zones, especially in warm, dry climates. Use trellis support for heavy colas and control late-flower humidity to avoid bud rot in dense top sites.

Comprehensive Cultivation Guide: Outdoor, Auto, and Fast Versions

AK-47 flourishes outdoors where summers are long, sunny, and relatively dry. In temperate climates, plant after the last frost, site in full sun, and consider raised beds for drainage and root aeration. Feed with a balanced vegetative regimen through solstice, then transition to bloom nutrition as days shorten.

Autoflower variants broaden AK-47’s versatility. Royal AK Auto and similar autos pack the classic profile into a compact, fast format that finishes in roughly 70–85 days from seed under 18–20 hours of light. Indoors, autos commonly yield 350–500 g/m²; outdoors, 50–150 g/plant is common depending on pot size, sunlight, and nutrition.

Growers also praise fast photoperiod versions for shortening harvest windows by roughly 1–2 weeks versus standard AK-47. SeedSupreme feedback highlights that AK-47 Fast Version (still photoperiod) performs well under intense sun, with one reviewer noting vigorous growth in Washington State’s high desert wine country. For standard feminized seeds, SeedSupreme notes that AK-47 is an “absolute breeze to grow” when temperatures and humidity are kept in range—advice that aligns with the strain’s reputation for forgiving cultivation.

Post-Harvest: Drying, Curing, and Storage

Dry AK-47 slowly to preserve monoterpenes and encourage an even chlorophyll breakdown. A classic target is 18–20°C and 55–60% relative humidity for 10–14 days, with gentle airflow that moves air but never directly fans the flowers. In dense colas, consider breaking large tops into smaller sections to prevent moisture pockets and mold.

Once stems snap rather than bend, trim fully and jar with reliable hygrometers, aiming for 60–62% RH. Burp jars daily for the first week, then every few days for an additional 2–3 weeks. Most growers notice a discernible jump in flavor complexity and smoothness after the 21–28 day cure mark.

Store final jars in a cool, dark place. Terpenes degrade from heat, oxygen, and UV exposure, so stable conditions extend the aromatic lifespan. Properly cured AK-47 can maintain peak character for 3–6 months, with quality remaining enjoyable well beyond if storage is airtight and climate-controlled.

Yields, Metrics, and Grower Benchmarks

Under well-tuned indoor conditions, AK-47 routinely achieves 1.0–1.8 grams per watt with modern LEDs and a trained canopy. A typical 1.2 m x 1.2 m tent with 480–650 W LED and four well-managed plants can produce 450–650 g per run. High-CO2 grows (800–1,200 ppm) with dialed VPD and fertigation schedules can push yields into the upper end of that range.

Plants tend to consume more magnesium during peak bloom; a 0.3–0.5 g/L magnesium supplement can prevent interveinal chlorosis under strong LEDs. Nitrogen should be tapered in late flower to avoid leafy buds and improve post-harvest burn. Monitor runoff EC to stay within ±0.3 of input EC; drifting higher signals salt accumulation and calls for a reset or lighter feeding.

Outdoors, 150–300 L containers or in-ground beds with living soil and robust microbiology can produce multi-pound plants where climate allows. Prophylactic IPM—sticky traps, weekly scouting, and mild biologicals—keeps aphids, mites, and caterpillars in check. AK-47’s dense colas make bud rot prevention a priority; light defoliation and diligent airflow pay dividends.

Notable Crosses and Influence

AK-47 has contributed genetics to many modern hybrids thanks to its reliable vigor and crowd-pleasing effect. Kali 47 (Kali Mist x AK-47) is frequently cited as a happy, relieving daytime option, blending two sativa-forward classics into an energetic yet balanced expression. Consumer reviews on Leafly often highlight mood elevation and stress relief with Kali 47, reflecting AK-47’s motivational core.

Amnesia x AK-47 feminized seeds combine two legendary profiles known for clarity and citrus-herbal lift. Vendors caution that potency can spike high, so starting low is recommended until you gauge tolerance—a sensible rule that mirrors best practices with standard AK-47. These crosses illustrate how AK-47’s clean, productive headspace remains valuable as a breeding anchor.

Commercial and homegrow mixes often feature AK-47 autos alongside crowd favorites because the strain brings predictability to multi-cultivar runs. For example, indoor autoflower packs may pair AK-47 Auto with compact champions like GG4 Auto and Banana Kush Auto for tent-friendly variety. Such bundles signal the market trust AK-47 has earned for flavor, form, and function.

Data-Backed Expectations and Consumer Guidance

Expect THC most commonly in the 17–22% range, with CBD below 1% and minor cannabinoids present at trace-to-low levels. Terpenes are often led by myrcene, with meaningful pinene and caryophyllene contributions and supporting limonene. This chemistry aligns with user reports of clear, upbeat focus that resists jitteriness.

For new consumers, 1–2 inhalations or a 2.5–5 mg edible dose is a prudent starting point. Experienced users typically find a comfortable range around 10–20 mg for edibles or 2–6 inhalations depending on device and tolerance. Because AK-47’s onset is quick, giving it 10–15 minutes before redosing helps prevent overshooting the mark.

Growers should budget 8–9 weeks of flowering, yields around 400–550 g/m² indoors, and medium stretch managed well with topping and ScrOG. Fast photoperiod versions may finish a week earlier, while autos finish in 10–12 weeks from seed. Environment control—especially humidity and airflow in late flower—is the decisive variable separating good from great results.
