AK by CopyCat Seeds is a modern, sativa-leaning reimagining of the famous AK-47 family, tuned for vigor, punch, and contemporary flavor demands. CopyCat Seeds is known for stabilizing popular lineages into feminized, high-output cultivars, and AK fits that mold with reliable structure and a bright, cerebral profile. While the original AK-47 gained global recognition in the 1990s, AK by CopyCat Seeds updates the classic traits with tighter internodes, more consistent resin production, and a terpene blend led by myrcene with notable pinene and caryophyllene.
In consumer reports and lab listings for the AK-47 lineage, total THC commonly falls in the mid- to high-teens with select phenotypes crossing 20% THC. Autos and fast versions built on the AK genome are typically advertised at 15–20% THC, with variable CBD depending on breeder selections. AK by CopyCat Seeds follows the mostly sativa blueprint, but growers frequently note a hybrid sturdiness that makes it accessible indoors or outdoors.
The hallmark AK experience remains intact: clear, upbeat, and functional, with an earthy-sweet aroma that pivots to cedar, pine, and pepper spice on the exhale. Leafly profiles of AK-47 confirm myrcene as the most abundant terpene, followed by pinene and caryophyllene—a combination that tends to balance relaxation and alertness. In practical terms, AK is a daytime-friendly cultivar for many users, combining a fast takeoff with an even-keel cruise window.
History and Origins
AK traces back to the 1990s wave of international hybrids that merged classic equatorial sativas with sturdy Afghan stock. The original AK-47 line is widely reported to blend Colombian (South American), Mexican, Thai, and Afghan genetics, delivering a hybrid with sativa-forward effects and hybrid-tier growability. These crosses were refined over multiple generations to stabilize yield, aroma, and potency while preserving a streamlined flowering time of roughly 8–9 weeks indoors.
As markets matured, breeders created numerous AK-derivatives, including autos and fast versions that trim flowering time by 1–2 weeks. CopyCat Seeds’ AK takes advantage of that heritage by selecting for consistent trichome density, sativa-leaning architecture, and the terpene stack that made AK famous. Growers who have worked classic AK-47 often recognize the same earthy-sweet bouquet and bright lift in CopyCat’s version.
The cultural impact of AK-style cultivars is substantial, with the original AK-47 frequently featured on “most influential” lists. It remains a go-to for breeders creating balanced hybrids that feel energetic without being jittery. The enduring appeal comes from its predictable greenhouse and indoor performance, paired with an effect profile that many find productive and sociable.
Genetic Lineage and Breeding Context
AK by CopyCat Seeds is best understood as a sativa-dominant selection refined off the AK-47 family tree. The classic lineage draws from Colombian and Mexican sativas (for citrus, herbal, and floral top notes), Thai landraces (for drive and headroom), and Afghan indica (for density, resin, and a manageable bloom time). CopyCat’s work focuses on stabilizing female expressions that enhance colas, resin coverage, and terpene concentration while suppressing herm traits.
Because the AK family has circulated for decades, phenotype variance still exists, especially regarding plant height, aroma dominance, and stretch. Sativa-leaning phenos typically show faster apical growth and a looser flower set early in bloom that swells into elongated, stacked spears. Afghan-influenced phenos remain more compact with chunkier bracts, slightly reduced stretch, and a pepper-forward nose from elevated caryophyllene.
In modern seed markets, AK-based autos and “fast versions” pool in additional genetics (often ruderalis for autos, or early-finishing photoperiod lines for fast versions). Seed retailers routinely list AK fast versions in the 15–20% THC range and medium CBD (1–5%) for specific offers, highlighting that breeder cuts can diverge from classic lab results. CopyCat’s AK is mostly sativa and photoperiod, built to deliver the familiar AK signature with contemporary uniformity for tents and rooms.
Appearance and Morphology
AK plants typically display a sativa-forward silhouette with medium internodal spacing and an apical dominance that lends itself to topping and low-stress training. Leaves often present as mid-green, with leaflet count leaning higher than average during vigorous vegetative growth. During pre-flower, expect a 1.3–1.7x stretch, with tall phenotypes approaching 2x in high-intensity environments.
Flowering sites begin as narrower clusters that progressively stack into tapered spears with a favorable calyx-to-leaf ratio. Growers commonly report calyx-to-leaf ratios around 2:1 to 3:1 on well-lit colas, which simplifies trimming and maximizes bag appeal. Mature pistils run from cream to tangerine, sometimes deepening to rust as the resin heads turn cloudy and amber.
Trichome coverage is one of the line’s calling cards, with heads evenly coating bracts and sugar leaves by mid-bloom (weeks 4–6). Under cooler night temperatures (15–18°C), trace anthocyanin expression can appear on sugar leaves or bract tips, though full-purple phenotypes are uncommon. Finished flowers are medium-dense for a sativa-leaning cultivar, avoiding the rock-hard compression that can raise botrytis risk in humid regions.
Aroma and Flavor
The AK signature opens with an earthy-sweet base accented by cedar, pine needles, and a pepper-spice tickle from beta-caryophyllene. Leafly reporting on AK-47 highlights myrcene as the dominant terpene, with pinene and caryophyllene following—a blend that fits what most noses pick up. Myrcene contributes damp earth and sweet herb, while alpha-pinene sharpens the bouquet with conifer, rosemary, and bright evergreen.
As flowers cure, the sweetness can shift toward light candied citrus and faint floral tea, underpinned by a woody backbone. Vaporization at lower temperatures (170–185°C) emphasizes herbal, pine, and tea notes with a cooling menthol-like lift from pinene. At higher temperatures (190–205°C), pepper and wood tones intensify, and the finish lingers with a mild resinous mouthfeel.
Smoke quality is typically smooth after a proper 3–4 week cure, with minimal throat bite compared with denser, diesel-forward cultivars. Grind texture tends to be fluffy and resinous, which helps joints burn evenly with a light-gray ash when properly flushed. In blind tastings, enthusiasts often describe AK as “forest-floor sweet” on the inhale and “peppery cedar” on the exhale, which aligns with the myrcene/pinene/caryophyllene triad.
Cannabinoid Profile and Potency
Across the AK-47 lineage in publicly available lab results, total THC commonly falls in the 16–20% range, with select cuts surpassing 20% under optimal cultivation. Seed vendors marketing fast versions and autos derived from AK routinely cite 15–20% THC, which is consistent with mainstream consumer potency expectations. CBD in classic AK-47 is usually low (<1%), though some fast or special selections are advertised as medium CBD (1–5%), indicating breeder-driven variability.
Minor cannabinoids are typically present in trace-to-moderate amounts. CBG is commonly detected in the 0.2–1.0% range in sativa-leaning hybrids harvested at peak milky trichomes, while CBC often lands below 0.5%. These minor constituents may subtly modulate the overall effect, especially when paired with a terpene total near or above 1.5%.
For practical dosing, many users find that 5–10 mg of inhaled THC equivalent yields noticeable uplift and focus without heavy sedation. Onset for inhalation is typically 2–10 minutes, with peak effects around 30–45 minutes and a total duration of 2–3 hours for most consumers. Oral preparations made from AK flower follow standard edible pharmacokinetics, with onset at 45–120 minutes and a longer 4–6 hour window.
Terpene Profile and Chemistry
Leafly identifies myrcene as the most abundant terpene in AK-47, followed by pinene and caryophyllene, and AK by CopyCat Seeds mirrors this profile in most reports. In lab-tested lots of AK-line cultivars, total terpene content often lands between 1.2% and 2.5% by weight, with standout batches exceeding 3.0% under optimized drying and curing. Myrcene commonly ranges around 0.4–0.8%, alpha-pinene around 0.15–0.30%, and beta-caryophyllene around 0.20–0.40%, with humulene, ocimene, and limonene appearing as secondary contributors.
Myrcene is associated with herbal, earthy aromatics and, in high proportions, can lean sedative, though in AK it is tempered by pinene’s alert, cooling quality. Pinene—often alpha-dominant over beta—adds forested clarity and can contribute to a perceived widening of focus when paired with moderate THC. Beta-caryophyllene, a sesquiterpene that acts as a CB2 agonist, introduces pepper spice and may underpin some users’ reports of physical ease.
The overall terpene synergy in AK trends toward balanced stimulation rather than racy energy. Users frequently describe feeling mentally engaged yet even, which reflects the interplay of pinene’s clarity with caryophyllene’s grounding tone. Vapor temperature dialing can selectively emphasize these compounds, with lower temps preserving pinene brightness and higher temps pulling more caryophyllene-forward spice.
Experiential Effects and Use Cases
AK’s effects are widely characterized as uplifted, clear-headed, and socially friendly, with less jitter than pure tropical sativas. Leafly’s editorial coverage of classic strains notes that AK-47’s pinene- and caryophyllene-rich profile supports an alert mental state without uppity overstimulation. CopyCat’s AK selection carries that same throughline: a quick cerebral lift followed by steady focus and a mild body ease.
First-wave effects include a mood lift and sensory brightness, often within 5 minutes of inhalation. This can segue into a zone of “clean motivation” that suits light creative tasks, conversation, or errands. The body effect tends to be present but not heavy, reported as softened shoulders or a loosened jaw rather than couchlock.
At higher doses, the headspace can intensify into a reflective, sometimes spacey state common to sativa-leaning hybrids with robust THC. Newer consumers should titrate slowly to avoid overshooting into anxious or racier territory. Many regular users reserve AK for daytime or early evening, using gentler evening cultivars for sleep if needed.
Potential Medical Applications and Considerations
Anecdotally, AK is used by some consumers to manage low mood, stress, or motivational dips during the day. The myrcene/pinene/caryophyllene stack is often cited for delivering mental clarity with a grounded edge, which some users perceive as stabilizing under pressure. Reports also include use for mild physical tension, particularly neck and shoulder tightness, without heavy sedation.
From a pharmacological perspective, beta-caryophyllene’s CB2 activity has drawn preclinical interest for anti-inflammatory potential, while pinene is frequently associated with alertness and perceived respiratory openness. These mechanistic notes are investigational and should not be interpreted as medical claims or guarantees of outcome. Individual responses vary with dose, tolerance, and set and setting.
Patients considering cannabis should consult a qualified clinician, especially those with anxiety disorders, cardiovascular conditions, or medication interactions. Start low and go slow is prudent, particularly with inhaled THC above 15%. For symptom tracking, keeping a simple log of dose, method, and effect can help identify patterns and optimal windows over several sessions.
Comprehensive Cultivation Guide
Overview and Growth Habit:
AK by CopyCat Seeds grows as a sativa-leaning photoperiod cultivar with a dependable 8–9 week indoor flowering window under 12/12. Plants show a 1.3–1.7x stretch after flip, which is easily managed with topping and low-stress training. Indoors, expect 450–550 g/m² under optimized LED or HPS lighting, with experienced growers pushing higher via canopy management.
Outdoors in full sun, a single plant in a 75–150 liter container can target 400–700 g per plant depending on season length and nutrition. Harvest timing typically lands from late September to mid-October in temperate zones. The structure favors SCROG or a multi-top manifold for cola uniformity.
Germination and Early Seedling Care:
Stable germination rates are typical across AK-line seeds when hydrated properly. As a general technique also recommended for Royal AK Auto seeds, a 12-hour soak in clean water prior to sowing can jump-start hydration and speed radicle emergence. After the soak, place seeds in a lightly moistened starter plug or 0.5–1 cm deep in seedling mix and maintain 24–26°C with 90–120 µmol/m²/s of light.
Seedlings thrive at 60–70% RH, 22–25°C, and a gentle airflow to prevent damping-off. Avoid overwatering; allow the top 1–2 cm of media to dry before reapplying. A weak nutrient solution (EC 0.6–0.8 mS/cm) with a root stimulator supports early vigor.
Vegetative Phase (2–6 weeks):
Target 20–24 hours of light for faster vegetative growth or 18/6 for efficiency. Provide PPFD around 300–500 µmol/m²/s, temperatures of 24–28°C day and 18–22°C night, and RH around 55–65%. Maintain pH at 5.8–6.2 in hydro/coco and 6.3–6.8 in soil, with EC 1.2–1.6 mS/cm depending on media and cultivar appetite.
Top at the 4th–6th node to break apical dominance, then begin LST to open the canopy. AK responds very well to SCROG; weave branches as they grow to maximize light capture and even cola height. Defoliate lightly, removing large fan leaves that block lower sites, but avoid aggressive stripping that could stall a sativa-leaning plant.
Transition and Flowering (8–9 weeks):
Switch to 12/12 and raise PPFD to 700–900 µmol/m²/s by week 2 of bloom. Expect a 1.3–1.7x stretch by week 3; manage with trellis support and tie-downs. Drop RH to 50–55% early flower, then 40–50% mid-flower, and 35–45% late flower to reduce botrytis risk in swelling colas.
Increase EC to 1.8–2.2 mS/cm as the plant builds biomass, emphasizing phosphorus and potassium after week 3. A light defoliation at week 3 and a second clean-up around week 6 help airflow and trichome exposure. Keep night temperatures 3–5°C lower than day to reinforce internodal stacking and color expression.
Irrigation and Nutrition:
Water to 10–20% runoff in inert media to prevent salt buildup; in living soils, irrigate to full saturation less frequently and let the pot lighten before the next watering. Calcium and magnesium supplementation is commonly beneficial under LED lighting; 100–150 ppm Ca and 40–60 ppm Mg is a typical target in coco/hydro. Silica (30–50 ppm) can improve stem rigidity and stress tolerance.
Monitor for nitrogen excess as AK transitions to bloom—dark, shiny leaves and clawing indicate reduction is needed. Aim for a balanced NPK in early flower (e.g., 1:1:1 ratio), shifting to 1:2:2 by mid-flower and 0:1.5:2 in late flower. Flush strategies vary by grower; many reduce EC to 0.8–1.0 mS/cm for the final 7–10 days to enhance burn quality.
Environmental Control and VPD:
Maintain VPD around 0.8–1.2 kPa in veg and 1.2–1.5 kPa in flower for strong transpiration and nutrient flow. Provide vigorous but non-damaging airflow—two to four oscillating fans per 1.2 × 1.2 m tent is a good starting point. Negative pressure and high-efficiency carbon filtration help control AK’s robust aroma as flowers mature.
Pest and Pathogen Management:
AK’s medium-dense colas require strict humidity control in late bloom to avoid botrytis. Prevent powdery mildew with good airflow, clean intake filters, and weekly leaf inspections; sulfur burners can be used in veg only, never on flowers. Scout for spider mites and thrips with yellow/blue sticky cards, and consider beneficials like Phytoseiulus persimilis and Amblyseius swirskii as a prophylactic.
Training Systems and Canopy Strategy:
SCROG maximizes yield by converting AK’s natural apical drive into a flat, light-saturated field of tops. For a manifold, top to 8–12 main colas and spread evenly with soft ties, keeping canopy height within 5–8 cm. Sea of Green (SOG) also works from rooted clones, running 16–25 plants per square meter with minimal veg for fast turnover.
Harvest Timing and Maturity:
AK tends to deliver its best balance of brightness and body when trichomes are mostly cloudy with 5–15% amber. At this point, cannabinoid and terpene expression usually peak, and volatile loss is minimized. Expect harvest between day 56 and day 63 of flower indoors under stable conditions.
Outdoor Considerations:
In Mediterranean climates, AK finishes comfortably before heavy October rains; in cooler regions, consider greenhouse covers to avoid late-season moisture. Plant in mounded beds or raised containers for drainage, and prune interior leaves to maintain airflow. Organic top-dressing with compost and dry amendments every 3–4 weeks supports steady growth without salt buildup.
Post-Harvest Handling, Curing, and Storage
Initial Drying:
Hang whole plants or large branches at 18–21°C and 55–60% RH for 7–12 days, depending on flower size and ambient airflow. Gentle air exchange and darkness preserve terpene integrity; avoid direct fan blast on flowers. Dry until small stems snap rather than bend, typically when moisture content approaches 10–12%.
Curing Protocol:
Jar the buds loosely in airtight containers, filling each to about 70–80% volume to leave headspace. Burp 1–2 times daily for the first week, then every other day for the next two weeks while stabilizing jars at 58–62% RH with humidity packs if needed. A 3–4 week cure often elevates AK’s cedar-pine sweetness and smooths the pepper finish.
Long-Term Storage:
For multi-month storage, keep sealed jars in a cool, dark place at 15–20°C and stable 58–62% RH. Avoid refrigeration/freezing unless vacuum-sealed to prevent moisture condensation and trichome brittleness. Properly cured and stored AK can maintain vibrant aroma for 6–12 months with minimal terpene fade.
Cultivar Variations: Autos, Fast Versions, and Phenotypes
Autos and fast versions derived from AK genetics offer flexibility in timing and space. Autos typically transition from seed to harvest in 9–11 weeks under 18–20 hours of light, returning 300–450 g/m² indoors with efficient scheduling. Fast versions can shave 1–2 weeks off bloom compared with standard photoperiods, sometimes finishing in as little as 7 weeks under ideal conditions.
Seed retailers have listed AK fast versions at 15–20% THC with medium CBD; however, CBD levels in classic AK profiles remain generally low. This discrepancy reflects breeder-specific selections and should be validated via local lab testing if cannabinoid ratios are critical. Phenotype hunting among 5–10 seeds of photoperiod AK often reveals a citrus-forward, a pine-forward, and a pepper-forward keeper.
For production grows, select for uniform stretch, high calyx-to-leaf ratio, and consistent terpene intensity to simplify scaling. Keep mother plants under 18 hours of light with moderate feeding, and take 12–15 cm cuttings for robust clones. Rooted clones typically establish in 7–10 days under 24–26°C and high humidity, accelerating SOG cycles.
Comparisons and Crosses
AK stands apart from racy, lime-zest sativas by being bright yet composed, owing to the pinene-caryophyllene ballast. Compared with diesel-heavy hybrids, AK presents fewer fuel notes and more herbal-cedar sweetness, improving broad appeal. In sessions, many rate AK as more talkative and functional than dessert-heavy indicas, yet less jittery than classic Haze cuts.
It also performs well as a parent in crosses, supporting yield, resin, and a balanced headspace. Many AK crosses—like Critical 47 and Kali 47—are known for pungency and cheerful effects, often leaning into skunk-sweet or spice-driven variations. CopyCat’s AK can serve as a modern parent to update old-school aroma with contemporary resin density.
For flavor chasers, pairing AK with limonene-forward cultivars can brighten the top end, while blending with humulene-rich lines deepens the woody, hop-like undercurrent. Breeders seeking speed can introduce early-finishing photoperiods to create fast hybrids that keep the AK personality. Always stress-test for herm traits and uniformity before scale-up.
Responsible Use, Tolerance, and Safety
Start with low doses and space sessions to evaluate AK’s cerebral lift and body balance. Tolerance can build with daily use; consider 48–72 hour resets to recalibrate. Hydration and nutrition matter—light snacks and water can smooth the onset and maintain comfort during longer sessions.
Individuals sensitive to THC should begin with one or two small inhalations and wait at least 10–15 minutes before redosing. If anxiety surfaces, changing environment, slowing breathing, or switching to a calmer activity can help ease the headspace. Avoid driving or operating machinery while under the influence, and keep products secured away from children and pets.
For medical contexts, coordinate with a healthcare professional regarding dosing, timing, and potential interactions, especially with sedatives or blood pressure medications. Vaporization allows finer dose control and often a cleaner terpene expression than combustion. Record subjective effects across several sessions to find your ideal terpene-cannabinoid window with AK.
