AK by Spliff Seeds is a modern, mostly indica take on one of cannabis’ most influential lineages. While many consumers associate the name AK with the storied AK-47 family, Spliff Seeds’ AK is bred to lean heavier into indica structure and behavior while retaining the balanced, functional lift that made the family famous. The result is a cultivar that pairs stout morphology and dense, resinous flowers with a terpene profile led by myrcene, supported by pinene and caryophyllene.
In today’s market, AK remains relevant because it offers consistency across key traits growers and consumers value: manageable height, reliable yields, and a widely appealing flavor. For consumers, it occupies a sweet spot between clear-headed motivation and body ease, avoiding the racy edges of some sativa-leaning classics. For cultivators, its predictability across environments and phenotypic coherence make it a dependable tent or field choice.
History and Cultural Impact
The AK family emerged in the 1990s during a wave of Dutch-bred hybrids that combined landrace building blocks from South America, Mexico, Thailand, and Afghanistan. Spliff Seeds’ AK is a house selection that channels this heritage toward a more indica-forward phenotype without abandoning the uplifting clarity associated with the line. This direction fits a broader consumer trend that favors hybrid functionality over narrow sativa–indica extremes.
The AK lineage helped define the balanced hybrid category and has been celebrated for decades in cannabis competitions and media coverage. Leafly has repeatedly highlighted AK-47 as a foundational strain, even listing it among the 100 most influential strains of all time, citing its South American and other global parentage and myrcene-dominant terpene profile. AK’s staying power is reinforced by its many offspring and crosses, which carry forward its signature alert, happy, and grounded effect profile.
The cultural influence of AK shows up in how widely it has been crossed, renamed, and reinterpreted by breeders across continents. Derivatives such as Critical 47 and Kali 47 demonstrate how the AK backbone adapts to different breeding goals, from increased sweetness and skunk to added euphoric clarity. That adaptability is a key reason AK is still referenced as a template when developing approachable hybrids for both new and seasoned consumers.
Genetic Lineage and Breeding Notes
Genetically, the AK family historically blends Colombian and Mexican tropical genetics with Thai sativas and Afghani indica. Leafly’s strain compendium notes South American contributions, and longstanding breeder accounts point to the Afghani component as the source of the line’s compact stature and dense calyx formation. Spliff Seeds’ AK emphasizes this Afghani-influenced, indica-forward architecture while maintaining hybrid vigor.
In practice, this means Spliff Seeds selected for phenotypes that finish faster, stack more densely, and manage canopy height. The breeder’s emphasis yields a plant that typically exhibits shorter internodal spacing and a calyx-to-leaf ratio favorable for efficient post-harvest trimming. These traits are consistent with indica-dominant selections but contrasted with the line’s sativa ancestry, which still shows up as clarity in the headspace and a slightly longer, more elastic flowering stretch than pure Afghani.
Breeding stability is evident in the way AK maintains its core terpene triad across many environments: myrcene, pinene, and caryophyllene. Leafly data explicitly identifies myrcene as the most abundant terpene in AK-47, followed by pinene and caryophyllene, and Spliff Seeds’ AK is widely reported by growers to echo this pattern. This conserved terpene architecture suggests targeted parental selection, backcrossing, or recurrent selection focused on aroma fidelity alongside yield and structure.
Botanical Appearance and Morphology
AK by Spliff Seeds grows with a distinctly indica-dominant posture: medium height, thick lateral branching, and compact nodal spacing. Indoors, plants commonly top out around 80–120 cm without aggressive training, making them suitable for tents and shorter rooms. Outdoors, expect 150–220 cm, depending on latitude, root volume, and season length.
Flowers form into dense, golf-ball to egg-shaped colas with a high calyx density and robust pistil coverage. Mature pistils typically shift from creamy white to apricot or rust, contrasting with lime to forest-green bracts that can occasionally express purples in cooler night temperatures. Trichome coverage is heavy, often producing a frosted appearance that signals strong resin production.
Vegetative growth is vigorous, especially in hydro or coco where nutrient delivery is rapid. The cultivar’s pre-flower stretch tends to be 1.5–2.0x, which is moderate compared to lanky sativa-leaning hybrids. This predictable stretch window helps SCROG cultivators plan net placement and canopy fill efficiently.
From a production standpoint, many growers report 450–600 g/m² indoors under 600–1000 W-equivalent LED lighting when grown in a dialed environment. Outdoors, yields can exceed 600 g per plant in favorable climates with 50+ liter containers and sufficient sunlight. Flowering time generally lands in the 49–63 day window (7–9 weeks), with indica-leaning phenotypes finishing earlier on that spectrum.
Aroma and Terpene-Driven Bouquet
Aroma in AK is anchored by earth and wet forest tones attributable to myrcene, layered with bright pine and conifer from pinene. Caryophyllene adds a peppery, warm spice that deepens the base and lends the bouquet a culinary edge reminiscent of cracked pepper and herbs. Together, these create an approachable scent that oscillates between fresh and grounding.
Many phenotypes show a light floral or sweet note that reads as honeyed cedar or apple skin, especially in early cure. As the cure progresses beyond two weeks, the spice tones round out and a faint musk emerges, reflecting caryophyllene and humulene interplay. Open-jar aroma intensity is medium to high, and total terpene content in well-grown batches often falls in the 1.5–3.0% range by weight, a band frequently observed for quality indoor flower.
Leafly identifies myrcene as the most abundant terpene in AK-47, with pinene and caryophyllene following, and Spliff Seeds’ AK closely mirrors this hierarchy. This constellation is also consistent with Leafly’s broader genre grouping that places AK alongside other myrcene-forward classics. The result is a nose that signals clarity and calm in equal measure, without the heavy diesel or extreme citrus that dominate other families.
Flavor Profile and Combustion Characteristics
Flavor tracks the aroma with a smooth, earthy inhale and a clean pine finish that lingers on the palate. Myrcene’s herbal earthiness acts as the foundation, while pinene contributes a minty, resinous lift on the exhale. Caryophyllene’s pepper dances at the edges, especially when vaporized at lower temperatures around 180–190°C.
In joints and bowls, smoke is typically soft and non-acrid when properly cured to 10–12% internal moisture, measured by hygrometer. Over-drying can mute the pine clarity and make the earthiness taste dusty, so keeping relative humidity around 58–62% in storage helps preserve nuance. Many users report the aftertaste as lightly sweet and woody, suggestive of cedar and spice rack notes.
When dabbed as rosin or solventless hash, AK concentrates skew toward herbaceous sweetness with a peppered finish. The terpene balance helps maintain flavor persistence across multiple pulls, with pinene staying bright even at modestly higher temperatures. A well-executed cure will keep the flavor cohesive rather than fragmenting into disjointed herbal and pepper components.
Cannabinoid Profile and Potency
Potency in the AK family is well documented, with many market tests placing AK-47 and close variants in the mid to upper-teens and low-20s for THC. SeedSupreme’s listing for an AK-47 Fast Version cites high THC in the 15–20% range, while acknowledging medium CBD between 1–5% in that specific selection. Spliff Seeds’ AK typically aligns with the high-THC, low-CBD pattern common to the family, though exact values vary by phenotype and cultivation.
In contemporary dispensary data sets, it is common to see total THC in AK-line flowers around 16–22%, total CBD below 1%, and total minor cannabinoids (CBG, CBC, THCV traces) comprising 0.2–1.0%. Some breeders have released CBD-leaning AK hybrids to diversify effect options, but these are distinct selections rather than the norm. Consumers should expect a high-THC, low-CBD experience unless the product is explicitly labeled otherwise.
For dosing, the general best practice of start low and go slow applies, especially for new consumers. The SeedSupreme note on Amnesia x AK-47 underlines that side effects are rare but advises cautious titration due to variable THC content between batches. For inhalation, a single small puff can deliver 1–3 mg THC; for edibles, starting at 2.5–5 mg THC is a prudent threshold until personal response is known.
Terpene Profile: Composition, Ratios, and Synergy
Across many lab-tested samples and user reports, AK’s terpene profile is led by myrcene with meaningful contributions from alpha- and beta-pinene and beta-caryophyllene. Leafly data states that myrcene is the most abundant terpene in AK-47, followed by pinene and caryophyllene, which aligns with the sensory profile reported by Spliff Seeds’ AK growers. Total terpene content often concentrates between 1.5–3.0% by weight for well-grown indoor flower.
Myrcene, the most common terpene in cannabis, brings earthy, herbal aromas and is associated anecdotally with a relaxing baseline. Pinene adds crisp conifer notes and has been linked in preclinical literature to bronchodilation and memory-supportive effects, potentially counterbalancing heavy sedation. Caryophyllene, a dietary cannabinoid terpene that binds to CB1/CB2 receptors, contributes pepper-spice depth and may modulate inflammatory pathways in preliminary studies.
Minor terpenes that may appear in measurable amounts include humulene, ocimene, and limonene. Humulene echoes woody and herbal tones while subtly suppressing appetite in some reports, whereas ocimene can add a sweet, green-floral lift. Limonene, when present, brightens the top end with citrus hints and can shift the mood profile slightly more upbeat.
The synergy of myrcene, pinene, and caryophyllene explains why many users experience AK as clear yet grounded. Leafly’s editorial characterization of AK-47 describes an alert mental state without uppity overstimulation, a description consistent with this terpene balance. In practical terms, this means users often feel mentally available for tasks while enjoying body ease that never fully tips into couchlock unless large doses are consumed.
Experiential Effects: Onset, Plateau, and Duration
Inhalation onset is typically felt within 2–10 minutes, with the first phase characterized by a lift in mood and reduced stress reactivity. Users often describe a gentle brightening of focus and an ease in social situations without jittery edges. As the session develops, a warm bodily relaxation sets in, softening tension in the shoulders and lower back.
The plateau phase generally lasts 60–120 minutes for inhaled use, extending to 3–5 hours for oral ingestion. During this window, AK’s indica-forward body qualities become more pronounced, especially if multiple inhalations are taken. Cognitive clarity tends to remain intact, making it popular for light creative work, chores, gaming, or nature walks.
At higher doses, the body heaviness can escalate toward stillness, and short-term memory lapses become more likely. Individuals sensitive to THC may experience transient anxiety if they overshoot their comfort zone, though this appears less common with AK compared to sharper, limonene-dominant cultivars. Hydration and pacing help maintain a comfortable experience.
Consumer reports and breeder notes frequently tag AK with happy, relaxed, and uplifted as core effects. This maps onto Leafly’s broader characterization and helps explain AK’s popularity across day and evening use cases. Late-night use can lead to easy sleep onset for many, while afternoon use is often described as undemanding and amiable rather than sedative.
Potential Medical Applications and Evidence
While controlled clinical trials on specific strains are limited, AK’s composition hints at several potential therapeutic niches. The combination of myrcene, pinene, and caryophyllene aligns with anecdotal reports of mood support, stress reduction, and mild analgesia. SeedSupreme’s overview of AK-47 Feminized highlights uplifting and mood-boosting qualities, consistent with many patient experiences.
Leafly’s entry for Kali 47, a cross of Kali Mist and AK-47, notes reported relief for depression, pain, and stress among patients, suggesting transferable traits from the AK lineage. Critical 47, another cross featuring AK genetics, is recognized for a pungent aroma and happy, relaxing effects, reinforcing AK’s utility for tension and low mood. These derivative strain reports, while not clinical proof, indicate pattern stability in how AK contributes to symptom management.
For anxiety-prone individuals, the pinene and caryophyllene combination may help keep the experience grounded and less likely to trigger racing thoughts compared to sharper citrus-forward profiles. However, anyone with anxiety sensitivity should adopt a gradual titration strategy and consider CBD balancing if needed. The caution from Amnesia x AK-47 sources about starting low until THC content is understood is well taken here.
Patients pursuing sleep support often find that moderate doses in the evening promote relaxation without the heavy next-day grogginess associated with more narcotic indicas. For pain, AK may assist with mild to moderate musculoskeletal discomfort, particularly when combined with heat therapy or stretching. As with all medical uses, individualized response varies, and consultation with a healthcare professional is recommended.
Comprehensive Cultivation Guide
Environment and planning: AK by Spliff Seeds is adaptable across soil, coco, and hydro, thriving in stable environments. Target day temperatures of 24–28°C and night temperatures of 18–22°C with RH around 55–65% in veg and 40–50% in flower. Maintain a VPD of approximately 0.8–1.2 kPa in veg and 1.2–1.4 kPa in late flower for optimal transpiration.
Lighting and PPFD: In veg, AK responds well to 400–700 µmol/m²/s, while in flower it performs best between 900–1200 µmol/m²/s depending on CO2 availability. Under 20–40% CO2 enrichment (900–1200 ppm), AK can assimilate higher PPFD closer to 1200–1400 µmol/m²/s if nutrients and irrigation are carefully matched. Keep canopy even with SCROG or LST to maximize light distribution.
Medium and nutrition: In coco, aim for an EC of 1.2–1.6 mS/cm in veg and 1.7–2.2 mS/cm in mid-flower, with pH 5.8–6.2. In soil, feed lightly at first, letting the medium’s CEC buffer nutrients, and irrigate with pH 6.2–6.8. AK often prefers moderate nitrogen early and a robust potassium and micronutrient supply during weeks 4–7 of flower.
Irrigation rhythm: Allow 10–15% runoff in soilless grows to prevent salt build-up, watering when the top 2–3 cm of medium is dry or when containers lose 40–60% of their saturated weight. AK’s indica-leaning rootball appreciates oxygen; avoid chronically saturated conditions. In living soil, mulch and consistent moisture help stabilize microbial activity and nutrient cycling.
Training: Topping at the 4th–6th node, followed by low-stress training, creates a flat, productive canopy. AK takes well to SCROG; set nets at 20–25 cm above the pot and weave during the first 14–18 days of stretch. For SOG, run more plants per square meter and limit veg to 7–10 days to keep single-cola architecture compact.
Flowering timeline: Expect a 1.5–2.0x stretch after flip, with many phenotypes setting definitive bud sites by day 14–17. Trichome production accelerates around week 4, and density increases substantially through week 7. Many growers harvest between days 52–63 based on trichome maturity and desired effect (clear–milky for brighter, milky–amber for heavier).
Pest and disease management: AK’s dense colas require good airflow; aim for 0.3–0.6 m/s across the canopy and prune lower larf to reduce humidity pockets. Prevent botrytis by keeping late-flower RH near 40–45% and avoiding foliage wetting. Implement a weekly IPM rotation early in veg with beneficial mites, neem-alternative oils, or biologicals, halting foliar treatments by early flower.
Germination and seedling care: Royal AK Auto sources note an excellent germination rate and suggest soaking seeds for around 12 hours before sowing. This pre-soak can improve uniformity by hydrating seed coats, especially for older seed lots. Plant 0.5–1.0 cm deep in a lightly moistened medium at 24–26°C, and maintain gentle light (200–300 µmol/m²/s) until the third set of true leaves.
Yield optimization: In 1–5 gallon containers indoors, a target yield of 450–600 g/m² is achievable with strong environmental control and training. Outdoor plants, given 7+ hours of direct sun and ample root volume, can surpass 600 g per plant. Maintain tight environmental stability during weeks 6–9 of flower to protect terpene retention and prevent foxtailing.
Harvest cues: Use a 60–100x scope to check trichomes; a 5–15% amber ratio often corresponds to peak potency with a deeper body effect. Pistil color alone is insufficient; rely on trichome maturity and calyx swell. Flush or taper nutrition during the final 7–10 days as per your cultivation philosophy and medium, prioritizing consistent dryback and flavor preservation.
Post-Harvest Processing, Curing, and Storage
Drying: Hang whole plants or large branches in 18–21°C with 50–60% RH for 7–14 days, aiming for a slow dry that protects terpenes. Gentle air movement that keeps leaves slightly fluttering prevents microclimates without desiccating the surface. Target a stem snap rather than bend before trimming to avoid grassy flavors.
Trimming and curing: Trim once surface dryness is stable, then jar flowers at 58–62% RH using humidity packs if needed. Burp jars daily for 7–10 days, then weekly for the next 2–4 weeks. A 4–6 week cure substantially improves AK’s pine clarity and rounds the peppery edges.
Storage: Protect from heat, light, and oxygen. Use UV-resistant jars, keep temperatures under 21°C, and avoid frequent opening to maintain terpene integrity. Properly stored, AK can retain strong aroma and potency for 6–12 months, though terpene levels gradually decline over time.
Concentrates: For hash making, AK’s dense resin heads and myrcene-led profile translate well to ice water extraction. Low-temperature press profiles (85–95°C plates, gentle pressure) preserve pinene brightness in rosin. Label jars with harvest and cure dates, and track sensory evolution to dial in your preferred cure length.
Comparisons and Notable Hybrids
When compared to citrus-forward hybrids like Tangie, AK offers a more grounded, forested profile that many find steadier for daytime tasks. Versus heavy gas cultivars, AK’s pine and pepper present cleaner on the palate and produce less perceived lethargy at moderate doses. This makes AK a versatile bridge for consumers who want clarity without sacrificing bodily ease.
Crosses such as Critical 47, which blends Critical Mass and AK-47, are known for a pungent, sweet-skunky aroma and happy relaxation that echoes AK’s mood profile. Kali 47, a Kali Mist x AK-47 cross, is often cited by patients for relief across depression, pain, and stress, hinting at the consistent, supportive character AK can pass to progeny. These examples reflect how breeders leverage the AK backbone when seeking stability in effect and aroma.
Royal AK Auto and various Fast Version offerings demonstrate how the AK family adapts to shorter seasons and faster harvest cycles. SeedSupreme lists AK-47 Fast Version with 15–20% THC and medium CBD possibilities in that specific selection, showing how the cannabinoid envelope can be modulated. For growers in marginal climates, these accelerated versions can deliver the AK experience with reduced risk from late-season weather.
Buyer’s and Grower’s Checklist
For buyers: Expect an aroma that starts earthy and piney with a peppery edge, not heavy citrus nor sharp gas. Verify lab data; most AK-type flower lands around 16–22% THC with CBD typically below 1% unless explicitly bred otherwise. Look for tight, resin-rich buds with frosty trichomes and a cure that preserves freshness without hay notes.
For home growers: Plan for 7–9 weeks of flower indoors and moderate stretch after flip. Use topping and LST or SCROG to distribute light across multiple tops, and keep late-flower humidity under 50% to protect dense colas. Consider a 12-hour seed soak before sowing, as noted for Royal AK Auto, to encourage even germination.
For medical users: AK’s combination of mood lift and body ease suits daytime stress relief and evening wind-down without heavy sedation at modest doses. If anxiety-sensitive, titrate slowly and consider pairing with CBD if needed. Track personal response in a simple journal noting dose, method, and effects to find your optimal window.
