Written by Ad OpsOrigins, Naming, and Breeder Overview
Amnesia TK is a modern hybrid bred by High Five Genetics, a boutique house known for crossing elite cuts to produce high-impact flavor and resin. The initials “TK” in cannabis typically denote Triangle Kush, a legendary Florida-bred OG that has influenced countless top-shelf hybrids. Paired with the “Amnesia” moniker, most enthusiasts infer a lineage that draws from the citrus-incense Amnesia family and the fuel-laden potency of Triangle Kush.
High Five Genetics lists Amnesia TK as an indica/sativa hybrid, and its structure and effects generally support that balanced designation. The cultivar targets consumers who want a cerebral spark without sacrificing body relief, an increasingly popular demand in legal markets. While not yet a household name, Amnesia TK’s pedigree cues align with “hall-of-fame” families frequently celebrated by mainstream lists.
Industry lists like Leafly’s 100 best weed strains of 2025 highlight how classic families continue to anchor consumer preferences. While Amnesia TK itself may not appear on such lists yet, its building blocks—Amnesia-type and Triangle Kush-type genetics—mirror the kind of profiles that have persisted for decades. This positions Amnesia TK as the kind of connoisseur hybrid that can credibly court both sativa-seekers and OG purists.
Because breeding programs evolve rapidly, specific release years and exact parent clone IDs can be fluid. As with many new-school hybrids, expect incremental updates from the breeder as hunting reveals standout phenotypes. Enthusiasts should consult the breeder’s latest releases or verified nurseries for the most current cut information.
Breeding History and Context
High Five Genetics operates in a contemporary landscape where breeders remix elite parents to create more stable terpene packages and consistent bag appeal. The Amnesia pillar contributes citrus, incense, and energizing headspace, while the Triangle Kush pillar brings petrol-heavy depth, density, and punishing potency. Breeding these together aims to solve a common consumer wish list: big aroma, smooth power, and day-into-night versatility.
Cannabis genetic documentation still varies across the industry, a point illustrated by databases that catalogue “unknown strain” genealogies and partial pedigrees. Resources that attempt to map unknown or partially documented lineages underscore how many modern hybrids rely on breeder-reported information rather than peer-reviewed records. In that context, High Five’s transparency about heritage families is helpful, even when exact clone IDs are proprietary or evolve with each new release.
The strategy mirrors how top-ranked strains often become progenitors for multiple crosses. Leafly’s 2025 top-100 overview shows that classics—Haze families, OG/Kush lines, and Chem/Diesel branches—recur because they deliver consistent consumer satisfaction. Amnesia TK slots neatly into that framework, leveraging proven parents to produce modern consistency and potency.
As with many projects in 2020–2025, breeders select for elevated resin, more stable chemotypes, and reliable yields under high-intensity lighting. Those targets reflect a maturing market where both home growers and commercial operators demand repeatable results. Amnesia TK’s breeding context thus fits current trends toward robust secondary metabolite expression and strong post-harvest bag appeal.
Genetic Lineage and Inheritance
The naming strongly suggests an Amnesia-family parent crossed to a Triangle Kush or TK-leaning OG, yielding a balanced indica/sativa hybrid. Amnesia lines, often tied to Amnesia Haze archetypes, are known for terpinolene- and limonene-forward bouquets with notes of citrus, cedar, and incense. Triangle Kush, in contrast, leans toward limonene, caryophyllene, and myrcene, expressing fuel, rubber, and earthy funk.
When these families meet, offspring often show a split of dominant phenotypes: about one-third that lean bright-citrus/incense, one-third fuel-forward and earthy, and one-third balanced. In practical terms, this means you may find both airy spear-like colas and denser OG-like golf balls within the same seed pack. The best phenotypes capture citrus-gas synergy with a resin output suitable for premium flower and solventless.
On the architectural level, Amnesia inputs raise internodal spacing and stretch, while TK inputs increase calyx density and leaf serration. Expect a moderate stretch of 1.5x–2.0x after flip, which is notably less than classic Hazes but more than squat, pure-Kush plants. With training, growers can shape a flat canopy that maximizes light use efficiency in mixed phenotypes.
While exact percentages are proprietary to breeders and can vary by selection, the indica/sativa designation reflects observable growth and effect patterns. Consumers typically encounter heady onset with grounded body relief, suggesting a roughly balanced chemo-phenotype. Growers will recognize the hybrid vigor that comes from crossing divergent but complementary families.
Appearance and Morphology
Amnesia TK presents a showy bag appeal that merges sativa architecture with OG density. Buds often start as elongated spears and finish with thickened calyx stacks, producing medium-to-high density flowers. Expect a high calyx-to-leaf ratio in top-tier phenotypes, easing manicuring and improving jar presentation.
Coloration ranges from lime to forest green with burnt-orange stigmas that deepen to rust at peak maturity. Under cool nights in late flower, some cuts display anthocyanin blushes along sugar leaves, a trait occasionally seen in modern dessert hybrids as well. While not as consistently colorful as known purple-forward varieties, the potential for subtle reds or purples adds visual interest.
Trichome coverage is prolific, with bulbous capitate-stalked heads that are desirable for hashmaking. Resin heads commonly fall in the 70–100 micron range, making dry-sift and ice water extraction feasible with proper agitation and milling. Under 10x magnification, resin density appears as a frosted layer, often described by growers as “sugar-dipped.”
Plant structure supports multiple topping events without losing vigor. Secondary and tertiary branches fill in well, and with light defoliation, lower sites can produce viable B-grade nugs. While not a towering Haze, it benefits from vertical room during the first two weeks of flower to accommodate its hybrid stretch.
Aroma: From Bag to Break
Aromatically, Amnesia TK marries bright top notes of lemon peel, sweet orange, and green apple with a base of petrol, rubber, and fresh earth. The first whiff from a sealed jar often reads as citrus-forward, a hallmark of Amnesia-leaning profiles. Upon breaking a nug, deeper layers unravel into fuel, black pepper, and incense, signaling the Triangle Kush influence underneath.
Dominant volatiles likely include limonene and terpinolene, supported by beta-caryophyllene and myrcene, with pinene and ocimene as accent notes. This matrix can generate a “lemon-sprite over gas-can” sensory effect that consumers compare to high-energy OG hybrids. The balance tends to shift slightly during cure, with fuel notes strengthening as monoterpenes volatilize and sesquiterpenes persist.
Compared with classic hybrids like AK-47, which are known to lean myrcene > pinene > caryophyllene in common analyses, Amnesia TK’s likely terpinolene/limonene leadership creates a brighter, more sparkling citrus bouquet. This distinction matters to consumers who differentiate between “earthy-mango” sativa scents and “lemon-incense-gas” sativa-leaning hybrids. It also influences perceived freshness at the point of sale since terpinolene-rich jars can smell explosive when properly cured.
Advanced testers sometimes note faint sulfurous undertones—trace volatile sulfur compounds—most noticeable at grind. While these are minute, they contribute to the “gas” descriptor that OG lovers prize. The result is a dynamically layered aroma that remains expressive from dry pull to the last third of the joint.
Flavor and Combustion Characteristics
On the palate, Amnesia TK typically opens with lemon zest, sweet-tart citrus candies, and evergreen on the inhale. Mid-palate transitions bring in white pepper, petrol, and a faint herbal bitterness reminiscent of grapefruit pith. The exhale finishes with creamy gas, cedar, and lingering incense, adhering to the OG-meets-Haze promise.
Vaporization at 170–185°C (338–365°F) prioritizes citrus brightness and terpinolene-driven top notes. Combustion at higher temperatures shifts the balance toward caryophyllene and humulene, emphasizing spice and diesel tones. Consumers who favor flavor clarity generally report the best expression through clean glass or a calibrated portable vaporizer.
Residual taste holds well for two to three pulls per pack or bowl before “toasty” tones dominate. Proper cure preserves the line’s sweetness; too fast a dry and you can lose perceived citrus by 20–30%. When dialed-in, the cultivar offers a dessert-like, lemon-cream finish that persists on the tongue for several minutes after exhale.
Terpene retention benefits from airtight storage at 0.55–0.62 water activity, which keeps volatiles in suspension without risking microbial growth. Under those conditions, jars can remain flavorful for 90–120 days before noticeable fade. Nitrogen-flushed packaging can extend shelf aroma by several additional weeks in commercial settings.
Cannabinoid Profile and Potency
In markets where hybrid potency averages have climbed, Amnesia TK competes comfortably with modern heavy-hitters. Batches commonly test in the 20–26% THCA range by dry weight, with occasional outliers on either side depending on phenotype and cultivation intensity. Post-decarboxylation, that equates to roughly 180–230 mg THC per gram of flower available to the consumer.
CBD generally trends low, often under 0.5%, consistent with both Amnesia and TK family lines. Minor cannabinoids like CBG can appear between 0.4–1.2%, with THCV occasionally popping at trace-to-low levels in sativa-leaning cuts. While these minors are not primary drivers of effect, they broaden the entourage matrix and can subtly steer the experience.
Total cannabinoid content regularly falls between 22–28% when summing THCA and minors. In absolute terms, that positions Amnesia TK near the upper third of premium shelf flower in many U.S. legal markets, where the median THC often sits around 18–22%. It’s potent enough that inexperienced users should approach with measured dosing.
For extracts and hash, resin from select phenotypes can yield 18–25% return on fresh-frozen ice water extraction, depending on wash protocol and harvest maturity. Live rosin can express a loud lemon-gas profile with THCA percentages exceeding 70% in well-processed batches. Such metrics make Amnesia TK attractive to solventless producers seeking both flavor and potency.
Terpene Profile and Volatile Chemistry
Expect total terpene content in the 1.5–3.0% w/w range in dialed-in, hand-trimmed flower. Dominant candidates include limonene (0.3–0.7%), terpinolene (0.3–0.9%), beta-caryophyllene (0.2–0.6%), and myrcene (0.2–0.6%). Supporting players like alpha-pinene, beta-pinene, ocimene, humulene, and linalool typically register at 0.05–0.25% each.
This composition creates bright, uplifting top notes while maintaining a peppery, grounding base—an aromatic synergy associated with increased perceived energy and focus. By contrast, a classic like AK-47 often shows a myrcene-dominant pattern with pinene and caryophyllene following, leading to earthier sweetness. Such comparisons help explain why Amnesia TK tastes more citrus-incense while AK-47 tastes more earthy-mango-pine.
Terpene stability depends on post-harvest handling. Monoterpenes like limonene and terpinolene evaporate faster than sesquiterpenes such as caryophyllene, so rushed drying can bleed off 30%+ of perceived citrus in a week. A slow, cool, 10–14-day dry retains a higher fraction of volatile monoterpenes, preserving that signature lemon-gas punch.
For lab-minded growers, monitoring headspace volatiles via SPME-GC-MS on sample jars can quantify retention over time. While not practical for most home gardens, this underscores how critical curing conditions are for the final flavor. Achieving 2.0%+ total terpenes reliably places Amnesia TK in connoisseur territory by sensory standards.
Experiential Effects and Onset Curve
Amnesia TK delivers a rapid-onset head effect within 2–5 minutes of inhalation, peaking at 30–60 minutes and sustaining for 2–3 hours. The front end feels elevating, with increased talkativeness, sensory detail, and a clear motivational nudge typical of Amnesia-type hybrids. As it settles, Triangle Kush influence adds warmth across the shoulders and a loosening of muscle tension without heavy couchlock.
Most consumers describe the mental tone as optimistic and goal-oriented when dosed moderately. At higher doses, a racy edge can surface in terpinolene-forward phenotypes, so set and setting matter for sensitive users. The physical arc remains comfortable, often characterized as a “floating” body effect that doesn’t fully sedate unless heavily dosed.
In practical terms, it suits daytime creativity, late-afternoon workouts, and social evenings that stretch into mellow nights. It can pair well with focused tasks like music production or design, where the citrus top note seems to keep the mind engaged. Overindulgence, however, may lead to brief task-switching and loss of focus, a common trait in high-THC sativa-leaning hybrids.
Side effects include dry mouth and dry eyes in the familiar range, with occasional transient anxiety in susceptible individuals at high intake. Beginners should start with 1–2 inhalations or 2.5–5 mg THC if ingesting, then titrate up. Experienced users often find 10–20 mg inhaled over a session to be a sweet spot for steady flow without jitter.
Potential Medical Applications
The cultivar’s mood-elevating profile makes it a candidate for daytime use among patients managing low mood, stress, or mild depressive symptoms. Observational surveys in cannabis patients frequently report improvements in perceived anxiety and stress burden, with 30–50% of respondents noting meaningful relief depending on dosage and product type. While Amnesia TK is not a medical product, its terpene balance aligns with profiles patients often select for these goals.
Pain relief is another plausible application, particularly for neuropathic and inflammatory pain where THC and beta-caryophyllene may contribute. Systematic reviews of cannabinoid therapy show moderate evidence for neuropathic pain relief, and patient registries often cite reductions in pain scores of 20–30% with routine cannabis use. The hybrid’s warm body effects can complement non-pharmacologic strategies like stretching or physical therapy.
Terpinolene-forward strains have been anecdotally chosen by patients seeking focus or fatigue relief. While rigorous randomized data are limited, patient-reported outcomes suggest improved activity initiation and interest in tasks with such chemotypes. Limonene, associated with citrus aromas, has been studied for potential mood-modulating properties, which may help explain consumer reports of elevated outlook.
As always, medical use should be discussed with a clinician, especially for individuals using other medications or living with cardiovascular, psychiatric, or seizure conditions. Starting at low doses and tracking outcomes in a simple log can help patients assess benefit-risk. Vaporized flower with titratable dosing is often preferred for rapid feedback and adjustment.
Comprehensive Cultivation Guide (Indoors, Outdoors, and Greenhouse)
Amnesia TK performs best with strong light, steady airflow, and consistent environmental control. Indoors, aim for 600–900 µmol/m²/s PPFD in late veg and 900–1,200 µmol/m²/s in mid-to-late flower. With supplemental CO₂ at 1,000–1,200 ppm, experienced growers can push PPFD toward 1,400 µmol/m²/s, provided canopy temperatures stay 25–27°C and leaf VPD targets are maintained.
Veg for 3–5 weeks depending on plant count and container size, topping 1–2 times to encourage lateral branching. Expect 1.5x–2.0x stretch after flip; deploy trellis netting or a SCROG frame to maintain a flat canopy. Light defoliation at day 21 and day 42 of flower helps airflow in hybrid phenotypes with denser leaf sets.
Flowering time generally finishes in 9–10 weeks from the first signs of pistils, with some TK-leaning cuts done at day 63–66 and some Amnesia-leaners pushing 70 days. By comparison, compact indica lines like Sensi Skunk can wrap in about 7–8 weeks, while Haze-forward cultivars can run longer. Expect higher resin and richer citrus notes if you let Amnesia-leaning cuts mature fully to 10 weeks.
Yield potential is competitive with modern hybrids. In optimized indoor environments, 450–600 g/m² is attainable, with advanced cultivators occasionally exceeding that under high-density planting and dialed CO₂. For context, top autos like West Coast OG Auto are advertised at 500–650 g/m², and heavy photoperiods like Himalaya Gold can reach 750–850 g/m²; Amnesia TK normally slots in between these with proper training.
Root media flexibility is high: coco coir with 20–30% perlite supports frequent fertigation and rapid growth, while living soil can enhance terpene complexity. In coco, run pH 5.8–6.2 and EC 1.2–1.6 in veg, 1.8–2.2 in peak flower, tapering the last two weeks. In soil, target pH 6.3–6.7 with balanced macronutrients and plentiful calcium and magnesium for robust cell walls and improved stress tolerance.
VPD targets of 0.9–1.2 kPa in veg and 1.2–1.4 kPa in flower keep stomata responsive without inviting pathogen pressure. Maintain RH at 60–65% in veg, 50–55% in early flower, and 45–50% late. Stable nighttime temps within 2–3°C of daytime minimize condensation and botrytis risk in denser TK-leaning buds.
Outdoor and greenhouse cultivation suit mild, Mediterranean climates with long, dry autumns. Plant after the last frost, top early, and use tomato cages or low-tension trellis to support expanding colas. In-ground plants can yield 500 g to 1.5 kg per plant with full-season veg, proper nutrition, and consistent IPM.
Integrated pest management should begin in veg with weekly scouting. Rotating biologicals like Bacillus subtilis and Beauveria bassiana, plus preventative sulfur (pre-flower only), helps keep PM and mites in check. Good airflow and strategic defoliation are crucial; the OG side packs density that can invite mold in humid regions.
Phenotype expression varies: Amnesia-leaners show increased internode length and lighter lime color, while TK-leaners are stockier and darker green. Both can respond well to topping, LST, and SCROG, but TK-leaners often produce tighter buds that demand more late-flower airflow. Cold nights can coax anthocyanins, similar to colorful modern dessert genetics like Blue Sunset Sherbert, though color is not guaranteed.
For harvest timing, track trichomes under 60–100x magnification. Many growers target 5–10% amber with most heads cloudy for a balanced effect; Amnesia-leaners may be ideal at fewer ambers to preserve “sparkle,” while TK-leaners tolerate a bit more for added body. Flush strategies vary by medium, but a 7–10 day plain-water or low-EC finish in coco and a gentle taper in living soil help smooth combustion.
Post-harvest, dry at 60°F (15.5°C) and 60% RH for 10–14 days, then cure in airtight containers at 62% RH, burping daily for the first two weeks. Hitting a water activity of 0.55–0.62 preserves terpenes and reduces oxidation. Under these conditions, the lemon-gas nose maintains intensity for months, supporting premium shelf presentation.
Phenotype Variation, Selection, and Processing
Expect three broad archetypes across seed runs: citrus-incense dominant, fuel-earth dominant, and a 50/50 balance. Citrus-dominant plants often test higher for terpinolene and limonene, with elongated colas and a lighter green hue. Fuel-dominant plants often show stronger caryophyllene and myrcene signals, denser OG-style buds, and darker leaves.
Select keepers by combining nose, resin, and structure. A keeper typically shows high trichome head density, strong stem rub during veg, and a consistent bouquet from dry pull to ash. In solventless trials, look for 4–6%+ fresh-frozen hash yield by plant weight as an early indicator of resin quality.
For flower, balanced phenos with loud lemon-gas and medium density cure most evenly and resist bud rot. For extracts, fuel-leaning phenos often deliver deeper gas and pepper in live rosin, while citrus-leaners can produce candy-lemon profiles prized by dabbers. Recording yield, terpene intensity, and consumer feedback across cycles accelerates your keeper hunt.
Compared to compact indica like Sensi Skunk or fast indicas like Blackberry Nuggets (often ready in 8–9 weeks), Amnesia TK needs slightly more patience. However, the increased aromatics and resin density can repay that time, particularly in premium markets. In effect terms, its daytime usability overlaps with sativa-leaning lines such as Pineapple Larry OG while adding OG grip for fuller body relief.
Post-Harvest Quality, Curing, and Storage
Drying at 60/60 for 10–14 days preserves monoterpene brightness better than a fast, warm dry. Hang whole plants or large branches to slow moisture loss, remove large fan leaves after 48–72 hours, and avoid direct airflow on flowers. A gentle dry that drops stem moisture steadily keeps chlorophyll degradation smooth and prevents hay smells.
Curing should begin once small stems snap and outer buds feel dry but not brittle. Use airtight glass or steel containers at 62% RH and 60–65°F (15.5–18.3°C), burping daily for 10–14 days and then weekly for a month. This regime can retain 70–85% of initial terpene intensity after 30 days compared to rushed methods.
If processing for extracts, freeze fresh material as quickly as possible after a short field trim to remove fan leaves. Keep harvest-to-freezer time under 60 minutes to minimize enzymatic degradation and terpene loss. For flower, avoid nitrogen burn in the last two weeks, as it can produce harsh smoke and mute citrus volatiles.
Long-term storage benefits from light- and oxygen-exclusion. Mylar, nitrogen-flushed cans, or dark glass with humidity control preserve both terpenes and cannabinoids; expect THC to slowly oxidize to CBN over many months. Properly stored, Amnesia TK holds competitive shelf life, retaining signature lemon-gas for 90–120 days with minimal fade.
Market Position, Consumer Demand, and Use Cases
Consumer data from legal markets show persistent demand for citrus-forward hybrids with OG depth, making Amnesia TK commercially relevant. Retail menus often segment effects into uplifting, relaxing, and balanced categories; Amnesia TK’s reported profile fits the uplifting-to-balanced band. This matches the pattern seen in annual roundups where Haze and Kush families continue to anchor best-seller lists.
From a buyer’s perspective, bag appeal is strong: frosted nugs, expressive nose, and a modern flavor trajectory from lemon to gas. That positions it well at premium price tiers, provided potency benchmarks (20%+ THC) and terpene numbers (2%+ total) are met. For processors, solventless suitability broadens SKUs across live rosin and fresh-press while maintaining brand flavor continuity.
In comparison with autos like West Coast OG Auto that are marketed for ease and yield, Amnesia TK offers photoperiod control and nuanced terpene expression more suited to connoisseur markets. It won’t typically match heavy outliers like Himalaya Gold on sheer weight per square meter, but it competes on flavor, resin, and versatility. For social, creative, or after-work scenarios, it provides a reliable arc that adapts from daytime uplift to evening wind-down.
As broader lists like Leafly’s top 100 celebrate classics, Amnesia TK’s parent families keep it aligned with enduring consumer tastes. That continuity helps retail staff confidently recommend it to both citrus-sativa fans and OG loyalists. Its cross-appeal reduces decision friction, improving the odds of repeat purchases and word-of-mouth growth.
Cultivation Benchmarks and Troubleshooting
Lighting: keep DLI in veg around 30–40 mol/m²/day and 40–50 mol/m²/day in flower, adjusting by PPFD and photoperiod. If leaves canoe upward mid-flower, reduce PPFD by 10–15% or increase CO₂ and fine-tune VPD. Light stress can volatilize monoterpenes prematurely and stunt resin formation.
Nutrition: the line responds well to a calcium-forward regime, with Ca:Mg around 2:1 and sufficient sulfur (50–80 ppm) for terpene biosynthesis. Excess nitrogen past week 3 of flower can suppress terpene expression and produce leafy buds. Aiming for EC 1.8–2.2 in peak bloom balances mass and flavor in coco; in soil, top-dress with balanced bloom organics at flip and mid-flower.
Pathogens: powdery mildew risk rises in dense TK-leaning phenos; maintain leaf surface temps and airflow, defoliate wisely, and avoid late foliar sprays. For botrytis, prune interior larf and keep night temps within 2–3°C of daytime to reduce condensation. Biological controls started early outperform rescue strategies started late.
Timing: some phenotypes appear “done” at day 63 with cloudy trichomes but benefit from an extra week for terpene polish. Monitor not just trichomes but also calyx swell and aroma intensity. Harvesting at peak aroma often correlates with the most expressive lemon-gas in the jar.
