Overview and Naming
Amnesia is a mostly sativa cannabis cultivar renowned for its brisk, cerebral lift, bright citrus-and-incense bouquet, and long, shimmering colas. In this profile, we focus on the Amnesia line produced by Pure Regular Seeds, which emphasizes the classic Haze-forward character while refining stability and vigor. Across dispensary menus and seed catalogs, the name 'Amnesia' can designate closely related but distinct selections, so clarity on breeder and chemotype matters.
In popular consciousness, Amnesia is frequently associated with energizing daytime use and creative momentum. Consumer-facing data consistently position it as a high-THC, low-CBD variety with a buoyant, talkative mood set. While Amnesia Haze is a separate, celebrated sibling with its own accolades, both share a family resemblance in terpene composition and uplift.
This cultivar’s appeal lies in its synergy of potency, flavor, and production. Growers value the combination of sativa stretch, dense resin, and respectable yields when properly trained and fed. Consumers gravitate toward the strain’s reliable euphoria and mood elevation, often described as clear, giggly, and outgoing.
Historical Background and Cultural Impact
Amnesia rose to prominence in the late 1990s and early 2000s as Dutch coffeeshop culture elevated Haze-type sativas with spacey head effects and electric aromas. Within a few years, the name became shorthand for a specific sativa experience—memory-scattering hilarity, social flow, and a lingering citrus-incense finish. The emergence of Amnesia as a separate label from Amnesia Haze reflected both breeding refinements and market differentiation.
Over time, the strain established a foothold across Europe and then global markets, aided by seed lines and clone-only cuts circulating among clubs and home growers. Online platforms and review communities consistently list Amnesia among the more energizing options, with mood-lifting effects often topping user reports. That reputation has persisted even as modern markets skew toward higher THC chemotypes and dessert terpenes.
Today, Amnesia endures as a reference sativa for consumers seeking creativity and optimism without the heavy body sedation of many indicas and dessert hybrids. Its cultural footprint includes memorable references in coffeeshop menus, connoisseur lists, and festival circuits. The cultivar also inspired offspring and hybrids that carry forward its bright terpene spine and animated headspace.
Genetic Lineage and Breeding Story
Amnesia is best understood as a Haze-dominant hybrid that integrates classic tropical sativa building blocks with select indica support for structure and resin density. Multiple breeder lines exist, and different catalogs have reported parents like Haze crossed with Skunk, Northern Lights, or Afghani to improve indoor performance. While exact recipes vary by breeder, the core phenotype expresses the hallmark Haze suite: citrus, spice, incense, and an elongated flowering cycle.
In this profile’s context, Amnesia by Pure Regular Seeds is a mostly sativa expression selected for vigorous vertical growth, high calyx-to-leaf ratios, and a terpinolene-forward aromatic signature. The Pure Regular Seeds work leans into Haze brightness while selecting for consistency and manageable internodal spacing. Growers can expect pronounced stretch and resin-heavy, tapering spears when environmental controls are dialed in.
Because the Amnesia label describes a chemotype as much as a genotype, clonally propagated cuts and seed-progeny may diverge. That variance explains why some growers report sharper lemon-and-zest phenotypes, while others emphasize woody incense and fresh herb. Nonetheless, the shared sativa lineage and effect profile unify the cultivar across reputable sources.
Botanical Morphology and Visual Traits
Amnesia plants typically display a lanky, upright posture with long internodes and rapid apical growth during the first three weeks of flowering. Indoors, trained plants stand roughly 90–160 cm, while outdoor specimens can exceed 180–300 cm with adequate root volume and sunshine. The stretch commonly reaches 1.8–2.5x after the flip, a classic Haze behavior requiring canopy management.
Mature buds form elongated, tapering colas with a high calyx-to-leaf ratio, lending a spear-like silhouette. The bracts swell and stack, producing a sparkling layer of trichomes that can make the flowers appear frosted with sugar, especially under cool night temperatures that intensify resin. Hues range from lime to forest green, with occasional amber pistils and, rarely, faint lavender undertones in cooler finish conditions.
Leaf morphology is mostly sativa: narrower leaflets, lighter leaf density, and vigorous lateral branching that responds well to topping and low-stress training. Stems can be surprisingly sturdy but will still benefit from trellising or stakes late in flower to prevent lean. Overall, the plant’s architecture rewards growers who plan for vertical space and airflow from the start.
Aroma and Bouquet
The Amnesia nose is unmistakably Haze-forward: bright citrus peel, fresh-cut herbs, and sweet-but-dry incense reminiscent of cedar and church resin. On the break, expect flashes of lemon zest and tangy orange, layered with peppery spice and a whiff of eucalyptus or menthol. These tones intensify as flowers cure, often revealing complex secondary notes of green mango and basil.
The dominant aromatic driver is commonly terpinolene, a monoterpene associated with fruity, floral, and piney facets. Supporting terpenes like myrcene, beta-caryophyllene, ocimene, limonene, linalool, and alpha-pinene round out the bouquet, pushing the aroma from simple citrus into a multidimensional haze. Properly cured lots often project strongly at room temperature, a good sign of terpene abundance.
Storage matters because monoterpenes volatilize quickly above 20–22°C and in low humidity. Maintaining jar humidity at 58–62% with minimal headspace helps preserve the lively top notes. When optimized, Amnesia’s aroma is both loud and surprisingly refined, offering sparkling citrus over fragrant wood and spice.
Flavor Profile and Combustion Characteristics
On the palate, Amnesia combines zingy lemon-lime entry with a sweet, resinous mid-palate and a peppered, woody finish. Vaporization at 175–190°C tends to highlight citrus-zest and herbal tea qualities, while combustion brings out sandalwood, pepper, and a faint anise-like snap. The aftertaste lingers as clean grapefruit pith blended with pine and a hint of basil.
Users often report that flavor intensity scales with a slow, cool cure of at least four weeks, which allows chlorophyll to degrade and esters to come forward. High-quality water pipes or clean glass preserve the top notes, whereas hot, dirty bowls can mute citrus and accentuate bitterness. For edibles, decarboxylation will diminish the delicate terps, but the citrus-spice signature can still peek through in infused oils.
Overall, properly grown and cured Amnesia offers a complex, layered experience that rewards mindful sipping. The flavor arc mirrors the effect arc: a bright takeoff, a smooth glide, and a tidy, aromatic landing. Connoisseurs often compare top expressions to a lemon-cedar tisane with a sparkling, mentholated lift.
Cannabinoid Profile and Potency Metrics
Across legal markets, Amnesia typically presents as high THC and low CBD, aligning with consumer reports and lab trends for Haze-forward sativas. In retail-tested samples, THC commonly ranges from about 18% to 26% by dry weight, with exceptional phenotypes approaching the upper 20s under optimized cultivation. CBD is usually below 0.5% and often near the assay’s limit of quantification, while total cannabinoids can land in the 20–28% range.
Minor cannabinoids may include CBG in the 0.3–1.5% range and trace THCV in select phenotypes, though THCV expression is variable and not guaranteed. These minor constituents can subtly contour the experience, with CBG sometimes correlated with a cleaner headspace and less racy edge. Nevertheless, the dominant psychoactive force is delta-9-THC, particularly in forms rich in monoterpenes.
Consumer-facing resources describe Amnesia as high THC and low CBD, and Haze relatives often test similarly. For example, Amnesia Haze is widely marketed as very high THC (often over 20%) with low CBD, a profile that tracks closely with Amnesia’s frequently observed lab results. As with any cultivar, batch-to-batch variation is expected due to phenotype selection, grower technique, and post-harvest handling.
Terpene Profile, Minor Compounds, and Chemotype
Amnesia’s terpene profile is typically terpinolene-dominant, a chemotype common in the Haze family associated with uplifting, euphoric mood states. In dispensary lab data for Haze-leaning cultivars, terpinolene often appears in the 0.3–1.2% range by weight, with total terpene content frequently between 1.5–3.0% under careful cultivation and curing. Supporting terpenes include myrcene (0.2–0.8%), beta-caryophyllene (0.1–0.6%), beta-ocimene (0.1–0.5%), limonene (0.1–0.4%), linalool (0.05–0.2%), and alpha-pinene (0.05–0.2%).
Terpinolene-limonene interactions may partially explain the bright mood lift reported by many users, while caryophyllene can add a grounded, peppery backbone. Pinene is often associated with alertness and perceived focus, though individual physiology heavily moderates these effects. Myrcene content in Amnesia tends to be moderate, which helps keep the body sedation lower than in many dessert hybrids with high myrcene.
Beyond terpenes, flavonoids and esters contribute to the subtle sweetness and tea-like aspects of the aroma. These compounds are sensitive to heat, oxygen, and time, underscoring the importance of gentle drying and sealed, humidity-controlled curing. Overall, Amnesia expresses a bright, volatile-rich chemotype whose liveliness is as much about preservation as production.
Experiential Effects and Use Patterns
Amnesia is prized for an uplifting, creative onset that many describe as energizing without being chaotic. Early in the session, users often report a gentle pressure behind the eyes, a buoyant mood shift, and a social, talkative spark. Body load is typically light-to-moderate, allowing daytime mobility and task engagement.
User reports align with broader Haze-family patterns, which emphasize euphoria, giggles, and conversation. In the context of related strains, Amnesia Haze is often summarized as giggly, euphoric, and talkative, with occasional negatives like dry mouth, dizziness, or paranoia in sensitive users. While Amnesia is distinct, these similarities make sense given the shared aromatics and high-THC, low-CBD composition.
Duration varies with dose and tolerance, but a typical inhaled session provides 2–3 hours of noticeable effects, with a gentle runway rather than a hard crash. High doses can increase headrush and may feel speedy for those prone to anxiety, especially in stimulating environments. As always, set, setting, and pacing strongly shape the experience.
Potential Medical Applications and Evidence
Amnesia’s mood-elevating qualities make it a candidate for daytime relief of stress, demoralization, and low motivation in experienced consumers. Anecdotally, patients report support for symptoms tied to depression and dysthymia, echoing descriptions of Amnesia as uplifting, creative, and euphoric. Because it is high THC and low CBD, careful dosing is crucial, particularly in individuals sensitive to THC-related anxiety.
Some patients with attention challenges find sativa-leaning chemotypes helpful for task initiation, though evidence is predominantly observational. The alert, pinene-tinged profile may contribute to perceived focus and flow, especially when combined with structured routines. For pain, THC-dominant profiles can aid neuropathic discomfort and improve pain-related sleep, but Amnesia’s stimulating character may be better suited to daytime flare-ups rather than nighttime use.
Appetite stimulation is common with THC, and Amnesia can assist in situations where mood-related appetite suppression is a concern. However, individuals with panic disorder, bipolar spectrum conditions, or a history of cannabis-induced paranoia may prefer lower-THC or CBD-rich options. Clinically, robust randomized data specific to a single named strain are limited, so any medical use should be guided by a clinician and personal response tracking.
Comprehensive Cultivation Guide: Environment, Medium, and Nutrition
Amnesia thrives in warm, well-ventilated environments with strong light and disciplined humidity control. Ideal daytime temperatures run 24–28°C in vegetative growth and 25–27°C in flowering, with night temperatures of 18–22°C to maintain resin density and minimize stress. Maintain RH around 60–70% in veg, 45–55% in mid flower, and 40–45% in late flower to suppress pathogens.
In hydro or coco, target a root-zone pH of 5.8–6.0; in soil, aim for 6.2–6.5. Electrical conductivity in veg often sits well around 1.2–1.6 mS/cm, rising to 1.6–2.0 mS/cm at early flower and peaking around 2.0–2.2 mS/cm in mid bloom before tapering to 1.4–1.6 for a clean finish. Keep a Ca:Mg ratio near 2:1 and ensure steady micronutrient availability to avoid interveinal chlorosis during the long bloom.
Sativas like Amnesia respond favorably to intense light but are heat- and nutrient-sensitive at the canopy. In early flower, 700–900 µmol/m²/s PPFD is a safe zone, increasing to 900–1100 µmol/m²/s as plants acclimate. With supplemental CO2 at 800–1200 ppm, the canopy can utilize 1000–1200 µmol/m²/s, provided VPD is held near 1.2–1.5 kPa to sustain gas exchange.
In soil and soilless mixes, provide ample aeration via perlite or pumice and avoid waterlogging. Allow 10–15% runoff in fertigation systems to manage EC drift, and keep irrigation intervals consistent to reduce stress. Amnesia’s long bloom benefits from steady potassium and phosphorus from week 3 onward, with a watchful eye on nitrogen to prevent leafy, delayed ripening.
Training, Canopy Management, and Plant Health
With a stretch potential of 1.8–2.5x, Amnesia rewards proactive training. Topping once or twice in veg followed by low-stress training and a wide net in a SCROG drastically improves canopy uniformity and light penetration. Space plant sites to allow 25–40 cm between main tops after training to minimize microclimates.
Grower anecdotes around Haze-leaning autos and photos note pronounced vertical push and occasional light burn when tops reach too close to LEDs. One experienced grower of an Amnesia Haze auto reported tying down multiple limbs, encountering mild light burn, and overfeeding the cultivar—lessons that translate well to Amnesia’s vigor. Keep LEDs at a safe 30–50 cm distance depending on fixture intensity, and adjust dimming instead of constantly raising lights during stretch.
Integrated pest management is vital given the extended flowering timeline. Weekly inspections for spider mites and thrips, combined with environmental discipline to deter powdery mildew, are crucial. Employ preventative bio-controls or gentle sprays in veg and the first week of flower, then cease foliar applications to protect trichomes and terpenes.
Defoliation should be moderate and strategic, focusing on interior leaves that block airflow and light to sites you intend to ripen. Avoid aggressive stripping in late bloom, which can stall resin maturation. Provide trellis layers or stakes by week 4–5 of flower to support swelling spears and prevent stem torque.
Flowering Behavior, Maturation, and Harvest Timing
Indoors, Amnesia generally flowers in 10–12 weeks (70–84 days) after the flip, with some phenotypes finishing closer to 9.5 weeks and others stretching into week 13. Outdoor harvests in the Northern Hemisphere tend to land from late October to early November, favoring Mediterranean or arid climates that can accommodate the extended ripening window. Patience is rewarded, as later weeks concentrate resin and drive terpene complexity.
Yield potential is strong with canopy management. Indoors, experienced growers commonly report 500–650 g/m² under high-efficiency LEDs, with CO2-enabled rooms nudging above 650 g/m². Outdoors, healthy plants with generous root space can achieve 600–900 g per plant in favorable conditions, though weather risk increases late in the season.
For target effects, use trichome color as a reliable indicator. For a bright, cerebral profile, harvest when trichomes are mostly cloudy with minimal amber (0–5%). For a slightly more balanced effect, wait for 10–15% amber, which adds body without muting the signature head lift.
Drying, Curing, and Storage Best Practices
After harvest, aim for a slow dry of 10–14 days at 18–20°C and 55–60% RH, with gentle airflow and darkness. This curve preserves monoterpenes like terpinolene and ocimene that evaporate readily at higher temperatures or in arid rooms. Stems should snap, not bend, and small flowers should feel dry to the touch but springy.
Transition to curing in airtight glass at 58–62% RH, burping jars daily for the first week, then every few days for weeks 2–4. A four-to-eight-week cure smooths the smoke, clarifies the citrus-herbal top end, and deepens the sandalwood-spice heart. For long-term storage, keep jars cool, dark, and stable; avoid repeated temperature cycling that can drive terpene loss.
If using humidity control packs, select the 58–62% range to balance burnability with preservation. For lab-like consistency, monitor water activity between 0.55 and 0.65. Properly cured Amnesia retains its trademark aroma for months, whereas rushed dries often collapse the bouquet into generic grass and pepper.
Phenotype Variations, Related Strains, and Comparisons
Within Amnesia lines, phenotypes cluster around two poles: a lemon-zest citrus bomb with brisk uplift, and a more incense-forward expression with deeper spice and wood. The citrus-heavy type is often brighter and zippier, while the incense-spice variant leans slightly more centering. Both retain the high-THC, low-CBD signature and benefit from careful environmental control.
It is helpful to distinguish Amnesia from Amnesia Haze, a related but distinct cultivar popularized in seed catalogs and strain databases. Amnesia Haze is frequently characterized by giggly, euphoric, and talkative effects, with potential negatives like paranoia, dry mouth, and dizziness in a subset of users. Amnesia shares much of that emotional profile, though the nuance of aroma and flowering time can differ by breeder and cut.
Amnesia also exists alongside offspring and cousins like Amnesia Lemon and other Haze-derived crosses that tweak flavor and effect. Such derivatives often shorten flower time or modulate the terpene backbone, trading a slice of the classic Haze arc for improved indoor convenience. When evaluating seed offers, check breeder provenance, flowering estimates, and reported dominant terpenes to align with your preferences.
Common Pitfalls, Safety, and Responsible Use
High-THC sativas like Amnesia can be deceptively potent due to their clean, buoyant launch. Start low and pace your session, especially in new environments or social settings. Sensitive individuals may experience anxiety, rapid heart rate, or racing thoughts at higher doses.
Hydration and electrolytes help manage dry mouth and maintain comfort, particularly during extended sessions. Avoid driving or operating machinery for several hours after use; impairment can persist beyond the peak euphoria, and reaction time may remain compromised. People with a history of panic attacks or psychosis should consult a clinician and consider alternative profiles with more CBD or lower THC.
In cultivation, avoid overfeeding early—Amnesia’s appetite ramps up mid-flower, not during early stretch. Prevent light burn by respecting fixture distances; a grower working with a closely related Haze auto reported needing to tie down multiple branches to stay off the diodes and still observed mild light stress. Above all, maintain airflow and humidity discipline to deter powdery mildew during the long finishing window.
Breeder Notes, Provenance, and Market Position
This profile centers on the Amnesia selection from Pure Regular Seeds, a mostly sativa expression curated for vigor, resin, and a classic Haze aromatic spine. In markets with multiple Amnesia labels, breeder identity and cut source are more predictive of outcome than name alone. If sourcing seeds or clones, request lineage notes, test results, and grower feedback to ensure alignment with your goals.
In consumer contexts, Amnesia continues to rank as a go-to mood elevator with creative energy and social ease. Crowdsourced reviews often echo phrases like uplifting, creative, and euphoric, consistent with the Haze family’s terpene-driven sparkle. These patterns parallel descriptions of Amnesia Haze on prominent platforms, further anchoring Amnesia’s position in the euphoric sativa segment.
Overall, Amnesia by Pure Regular Seeds sits at the intersection of classic Haze character and practical indoor adaptability. It is a strong choice for growers who enjoy training and long-running bloom projects, and for consumers seeking vivacity without heavy sedation. With attentive cultivation and post-harvest care, it delivers the clarity, flavor, and resin that made the name famous.
Evidence From User Reports and Public Databases
Public-facing strain databases consistently describe Amnesia as high in THC and low in CBD, with uplifting, creative, and euphoric effects. In closely related entries for Amnesia Haze, the top reported positives include giggly, euphoric, and talkative, with negatives such as paranoia, dry mouth, and dizziness in a minority of users. These parallels reflect shared Haze-family chemistry and align with observations that terpinolene-rich profiles tend to feel lively and social.
Seed catalogs frequently market Haze-line Amnesias with THC levels over 20% and CBD below 1%, consistent with independent lab trends in many retail markets. While results vary by grower and environment, this range is a reasonable expectation for properly cultivated, dialed-in plants. Reports from growers of Amnesia Haze autos and photos describe tall stature, need for tie-downs, and sensitivity to high-intensity lighting at close range—traits mirrored in Amnesia’s stretch and vigor.
As with all crowdsourced data, self-selection and reporting bias are possible, but the convergence of descriptors across platforms lends credence to the overall profile. When evaluating new batches, shoppers can cross-check dispensary COAs for THC, minor cannabinoids, and terpenes like terpinolene, myrcene, and caryophyllene. Such transparency helps ensure the purchased flower matches the desired experience.
Yield Optimization and Practical Metrics
For indoor growers targeting performance, a veg period of 3–5 weeks with one or two toppings sets up an even screen for a SCROG. Under efficient LEDs, a PPFD map targeting 700–900 µmol/m²/s early bloom and 900–1100 µmol/m²/s mid-to-late bloom balances intensity with stress. With CO2 enrichment and dialed VPD, advanced rooms can push productivity toward or beyond 650 g/m².
Nutrient strategy should pivot around stable calcium and magnesium support and a rising K:P emphasis from week 3 onward. Keep nitrogen in check after week 4 of flower to prevent excess leaf and delayed senescence. In coco/hydro, maintain runoff EC within 0.2–0.4 mS/cm of input to avoid salt creep; periodic flushes with balanced, low-EC solution can reset roots without starving the plant.
Outdoors, success depends on climate. Mediterranean, subtropical, or arid locales with long autumns allow full expression and big yields of 600–900 g per plant, especially in 50–100+ liter containers or in-ground beds. In temperate zones with early fall rains, consider greenhouses or light dep to avoid late-season botrytis and to harvest during safer weather windows.
