Amnesia emerged from the Dutch scene during the late 1990s and early 2000s, a time when Haze-influenced hybrids were reshaping coffee shop menus across Amsterdam. While multiple breeders have worked this line over the decades, GreenLabel Seeds stewarded a notable version that captured the vigorous growth and cerebral shine associated with classic Haze ancestry. In coffee shops, Amnesia became synonymous with high-spirited sessions, animated conversation, and a signature lemon-spice bouquet that regulars learned to recognize from meters away. The name stuck because of the strain’s tendency at higher doses to produce mild forgetfulness and a dreamy, time-suspending headspace that set it apart from heavier indica fare.
The broader Haze family earned global acclaim with multiple High Times Cannabis Cup victories in the same era, and Amnesia rode that swell in popularity into mainstream recognition. By the mid-2010s, Amnesia or its close cousins appeared on a substantial share of European dispensary menus, with many retailers labeling it a reliable daytime pick. Industry observations noted that sativa-leaning Haze hybrids, including Amnesia, often commanded premium shelf space thanks to their aromatics and energetic mood lift. This momentum helped standardize expectations: shoppers looked for bright citrus, soaring euphoria, and a long-lasting, clear high.
Although it is often conflated with the related Amnesia Haze, Amnesia occupies its own niche in the pantheon. Leafly characterizes Amnesia as uplifting, creative, and euphoric, with a high THC and low CBD profile that fits its lively reputation. The GreenLabel Seeds selection contributed to the cultivar’s identity by balancing sativa vigor with manageable internodes and a robust resin finish. Over time, this consistency drew both hobbyists and commercial growers who wanted repeatable results from a heady strain in the Haze lineage.
Amnesia’s cultural footprint extends into art studios, music sessions, and social gatherings where talkative, giggly energy is prized. Its reputation dovetails with user reports that compare its buoyant vibe to the standout members of the Haze family. As a result, Amnesia became a go-to recommendation for enthusiasts seeking creative stimulation without sacrificing flavor or aromatic complexity. That mixture of performance and personality helped cement Amnesia as a perennial favorite in modern cannabis culture.
Genetic Lineage and Breeding Notes
Amnesia is an indica/sativa hybrid with unmistakable Haze parentage, and many breeder notes point to a backbone built from classic Haze genetics combined with an Afghan or Skunk influence. While exact recipes vary by breeder, a common throughline includes Thai, Jamaican, and Mexican sativa ancestry tempered by Afghani structure and resin density. GreenLabel Seeds’ take on Amnesia aims to synchronize these components, capturing the high-spirited uplift of Haze while restraining the extreme lankiness typical of pure tropical sativas. This helps the cultivar remain productive under indoor ceilings while preserving the iconic citrus-spice bouquet.
Historically, Amnesia gets mentioned alongside Super Silver Haze and other hallmark sativa hybrids that defined the Amsterdam era. The shared chemistry often points to terpinolene-forward terpene ensembles that correlate with energetic and euphoric profiles. That connection is consistent with Leafly’s coverage of Haze family terpene signatures, where terpinolene, limonene, and myrcene frequently shape the sensory profile. In practice, this means GreenLabel’s Amnesia selection was likely guided by aroma, effect, and growth habit in equal measure.
Open-source grow logs and dispensary lab tags commonly place Amnesia’s THC range in the high teens to mid-20s, while CBD typically stays below 1%. This aligns with reports for Amnesia Haze from multiple seed vendors, which note very high THC and low CBD values, often over 20% THC and 0–1% CBD. The overlap in lab outcomes suggests that Amnesia and its closely related cousins share not only ancestry but also chemotype tendencies. A breeder stabilizing Amnesia thus prioritizes both potency and a consistent, euphoric sativa feel.
Because Amnesia has circulated widely, phenotype expression can vary from lime-forward, incense-bright plants to spicier, woodier versions. Growers who hunt through multiple seeds may discover a slightly more indica-leaning structure or a tall, spear-shaped sativa form. GreenLabel Seeds’ work appears to narrow that spread by favoring vigorous, high-yielding plants with strong resin coverage and unmistakable Haze lift. This phenotype discipline makes the cultivar a reliable performer in both home gardens and scaled rooms.
Botanical Appearance
Amnesia typically grows tall and assertive in vegetative growth, with medium-long internodes and a posture that invites low-stress training and topping. Leaves tend to be slender to mid-width, reflecting its sativa-heavy influence, and they maintain a healthy green when fed and lit correctly. During stretch, expect a 1.5x to 2.5x increase in height as flower initiates, a trait consistent with the Haze family’s tropical ancestry. Mature plants often showcase strong leaders and lateral branches that benefit from trellising or a SCROG net.
The flowers present as long, tapering spears with high calyx-to-leaf ratios and abundant trichome coverage. Buds are typically lime to forest green, accented by plentiful burnt-orange pistils that darken as they mature. While not as rock-hard as contemporary indica-dominant hybrids, Amnesia nugs remain fairly dense for a Haze-influenced cultivar, especially in cooler, well-ventilated rooms. This structure reduces trim time and enhances bag appeal thanks to prominent resin heads.
Under quality lighting, trichome density is notable, leading to strong extraction returns for dry sift, rosin, and hydrocarbon concentrates. Flower rosin yields commonly land in the 15–22% range when squished at optimal moisture and temperature, with skilled operators reporting even higher returns from particularly resinous phenotypes. Hydrocarbon extractions can exceed 20% yield on dry weight, reflecting the cultivar’s high resin output. These figures align with the cultivar’s reputation as a producer for both smokable flower and concentrates.
When grown outdoors, Amnesia tends to form large, spear-like colas that can reach significant lengths in long-season climates. The plant’s natural vigor encourages multiple tops if trained early, creating a candelabra canopy that absorbs sunlight efficiently. The longer flowering period relative to many hybrids means careful attention to fall weather is essential to avoid late-season moisture issues. In greenhouse environments, this cultivar’s upright frame pairs well with vertical support and aggressive defoliation strategies.
Aroma and Bouquet
Amnesia’s aroma is immediately identifiable: bright citrus peel followed by sweet spice and incense-like undertones. Many cuts also contribute a subtle cedar or sandalwood component, creating a layered bouquet that is at once fresh and deep. On the grind, the lemon sharpens and is joined by hints of herbal tea, wet stone, and a measured, peppery tickle. This aromatic complexity is consistent with a terpinolene-limonene-myrcene axis typical of the Haze family.
As flowers cure, the top notes can evolve from zingy citrus into a candied lemon profile, with sesquiterpene spice peeking through. Well-cured batches often deliver an effusive jar appeal that fills a room quickly, a common trait observed in dispensaries handling Haze-forward inventory. Terpene totals of 1.5–3.0% by weight are realistic for strong examples, with some outliers exceeding that in meticulously grown and handled flower. The interplay of bright monoterpenes and deeper sesquiterpenes lends Amnesia its signature throw.
Growers frequently report that environmental dialing during late flower significantly affects aroma intensity. Lower night temperatures and precise humidity control enhance monoterpene retention, keeping the citrus high-note crisp. A slow dry at 60–60 conditions and a cure extending 4–8 weeks can dramatically polish the bouquet, allowing the cedar and spice to harmonize under the lemon top note. These post-harvest practices often separate a merely good batch from an elite one.
In comparison to its close relative Amnesia Haze, Amnesia can be slightly less floral and more citrus-forward, though phenotypes blur the line. Amnesia Haze often emphasizes perfumed, exotic notes, while Amnesia tends to balance zest and spice with a clean, herbaceous finish. Both, however, share the invigorating Haze-family fingerprint that many enthusiasts immediately recognize. This is a primary reason the cultivar continues to perform strongly in the jar test with seasoned consumers.
Flavor and Mouthfeel
On inhalation, Amnesia presents a bright lemon entry that fans of classic Haze strains will find familiar. The citrus is quickly followed by sweet, herbal tea notes, then a mild peppery exhale that lingers on the palate. On the second pull, a cedar-like woodiness and faint incense layer deepen the profile, making for a dynamic flavor arc across each hit. The aftertaste is clean and slightly zesty, often encouraging another draw.
The mouthfeel is smooth when properly flushed and cured, with a light, almost sparkling sensation from the citrus-forward terpenes. Poorly dried batches can taste grassy and muffle the lemon top note, emphasizing the importance of a patient cure. When dialed in, the strain’s monoterpenes convey a crisp, effervescent character that pairs nicely with seltzer or tea. Vaporization accentuates this brightness, making terpenes like terpinolene and limonene pop at lower temperatures.
Edible infusions retain aspects of Amnesia’s flavor, translating as lemon zest and green herb in butter or MCT-based preparations. The peppery kick can emerge more strongly in tinctures, especially those taken sublingually, where beta-caryophyllene contributes a gentle tingle. Cold-ethanol extractions produce clean-tasting concentrates that preserve more of the citrus aromatics than hot, prolonged extractions. For concentrates, temperatures in the 480–520°F range on enails often deliver the full flavor spectrum without scorching.
Many consumers compare Amnesia’s flavor favorably against other Haze-descended favorites like Super Lemon Haze and Amnesia Haze. Compared to Super Lemon Haze’s candy-lemon dominance, Amnesia can feel more balanced and wood-spice layered. Compared to Amnesia Haze’s floral-incense bouquet, Amnesia leans crisper and more citrus-zest forward, depending on pheno. This balance makes it approachable for those who like lemon but want more than a one-note profile.
Cannabinoid Profile and Potency
Amnesia routinely tests high in THC, with many modern lab results clustering between 18% and 26% total THC in well-grown flower. Commercial batches in mature markets often record a mean around 20–23% THC, with top-shelf selections pushing the mid-20s. CBD typically remains low, frequently below 0.5%, and seldom exceeding 1%. This aligns with market reports of very high THC and low CBD for related variants, including Amnesia Haze offerings.
Among minor cannabinoids, CBG often appears in the 0.3–1.0% range, with CBC commonly 0.1–0.4%. THCV can show in trace to modest amounts in some phenotypes, occasionally reaching 0.2–0.5% where Haze lineage is strong. These numbers vary significantly by environment, harvest timing, and post-harvest handling. For extraction, the resin-rich flowers provide ample cannabinoids for both solventless and solvent-based workflows, with potency preserved by a careful cold chain.
Converted into mass terms, a 22% THC flower contains approximately 220 mg of THC per gram of dry weight. By contrast, a 0.5% CBD reading reflects about 5 mg per gram, underscoring the cultivar’s THC-driven experience. Consumers sensitive to THC should titrate carefully, as even small changes in dose can shift Amnesia from energized to racy. Edible makers often standardize at 2.5–5 mg THC per serving for novice-friendly offerings when formulating with this strain.
For medical users who need balanced ratios, Amnesia’s cannabinoid profile is typically not the best fit without blending. Some producers pair Amnesia concentrates with high-CBD extracts to target a desired ratio like 1:1 or 2:1 (CBD:THC). This blending can maintain Amnesia’s terpene-driven effect character while moderating the THC intensity. In all contexts, lab testing on each batch remains essential for predictable dosing.
Terpene Profile and Chemistry
Amnesia expresses a terpene profile common to the Haze family, with terpinolene frequently leading the ensemble. In lab reports, terpinolene has been observed in the 0.4–1.2% range by dry weight in Haze-line cultivars, and Amnesia often falls within that window. Limonene commonly comes next around 0.3–0.7%, while myrcene can range from 0.2–0.8% depending on phenotype and growing conditions. Beta-caryophyllene typically appears between 0.2–0.5%, contributing a gentle spice underpinning.
Ocimene is another recurring player in Haze-like profiles, commonly appearing in the 0.1–0.6% range and adding a sweet, herbaceous brightness. Trace linalool, often 0.05–0.2%, softens the edges and contributes to perceived floral tones. Together, these terpenes generate the signature lemon, sweet spice, and incense-wood sensations that define Amnesia in the jar and on the palate. Total terpene content frequently lands between 1.5% and 3.0% by weight in meticulous grows.
Leafly’s analysis of Haze family chemistry links terpinolene-dominant profiles to uplifting, euphoric, and creative experiences. This is consistent with the noted effects for both Amnesia and Amnesia Haze, which are described as uplifting, talkative, and giggly, respectively. While correlation is not causation, the pattern repeats across many Haze-family strains and consumer reports. That repeatability gives growers and consumers a data-informed expectation of how Amnesia will smell, taste, and feel.
Cultivation and post-harvest practices materially impact terpene retention for Amnesia. Cooler nights in late flower, gentle handling, and a slow dry can preserve volatile monoterpenes like terpinolene and limonene. Overly high drying temperatures or rushed cures can depress top-note intensity by 20–40% relative to careful slow-curing approaches. These variables directly translate into the perceived potency of aroma and flavor in finished flower.
Experiential Effects and User Reports
Most consumers describe Amnesia as uplifting, creative, and euphoric, an assessment echoed by Leafly’s summary for the strain. The high is front-loaded with cerebral clarity and energy, easing into a sustained, talkative sociability. Many users note a giggly, positive vibe similar to reports associated with Amnesia Haze, which is often described as giggly, euphoric, and talkative. The initial rush can sharpen focus for light, imaginative work or animated conversation.
Physiologically, Amnesia can increase heart rate modestly in sensitive individuals, especially during the first 15–30 minutes after inhalation. Onset for smoked or vaporized flower is typically within 2–5 minutes, with peak effects around 20–40 minutes and a total duration of 2–3 hours. Edible forms lengthen the timeline considerably, with onset around 45–90 minutes and peak effects up to 4 hours after ingestion. As with many high-THC strains, hydration and light snacks can smooth the experience.
Common side effects include cottonmouth and dry eyes, with occasional reports of dizziness and anxiety, especially at doses that exceed one’s tolerance. Leafly notes paranoid feelings and dizziness among possible negatives for related Haze cultivars, and these can appear with Amnesia when pushed too far. For newcomers, 1–2 inhalations or 2.5–5 mg THC in edibles is a prudent starting point. Allow a full 15–20 minutes between puffs when inhaling to gauge the trajectory.
At moderate doses, Amnesia’s uplift often enhances music, light exercise, and social settings. Many users report a sense of mental brightness without heavy body sedation, making it a daytime-friendly option for creative tasks. At higher doses, the strain’s namesake can surface as a dreamy distractibility and short-term memory slips. This shift underscores the importance of careful titration to keep the experience buoyant rather than overwhelming.
Potential Medical Applications
Amnesia’s high THC, low CBD profile and terpinolene-limonene-forward terpenes align with user reports of mood elevation, stress relief, and increased motivation. Observational data from patient communities suggest potential benefits for short-term relief of low mood and fatigue-like states, where a stimulating headspace is desired. Some patients use Amnesia as a daytime adjunct to manage stress, leveraging its talkative, sociable lift. The giggly, euphoric tone reported in Haze-family strains may ease social anxiety in certain individuals, although others can experience the opposite effect if dosing is too high.
The energizing properties can be useful for addressing lethargy associated with some depressive symptoms, but high-THC strains can also exacerbate anxiety in susceptible users. Because CBD content is typically under 1%, patients seeking anxiolytic moderation often blend Amnesia with CBD-rich flower or tincture. Ratios like 1:1 or 2:1 (CBD:THC) may maintain uplift while tempering the edge. Terpenes like limonene and linalool may further shape affect, with limonene often associated with a brighter mood and linalool with calm.
For pain, some users find that Amnesia’s distraction, improved mood, and mild anti-inflammatory potential from beta-caryophyllene provide functional relief, particularly for mild to moderate discomfort. However, for severe pain or conditions favoring sedative relief, more myrcene- or linalool-dominant cultivars might be preferred. Amnesia’s stimulating frame can be counterproductive near bedtime for some, though others report a gentle comedown conducive to relaxation as the peak fades. As always, individual response varies, and medical supervision is recommended when using cannabis therapeutically.
Patients should prioritize lab-tested products and consistent dosing routines. Vaporization allows precise titration and can reduce respiratory irritants compared to combustion. Edibles provide longer coverage but require patience and conservative initial dosing to avoid overshooting the therapeutic window. If anxiety or dizziness appears, stepping down the dose or introducing CBD can help recalibrate the experience.
Comprehensive Cultivation Guide
Amnesia grows vigorously with a pronounced stretch and a flower time typically ranging from 9 to 11 weeks indoors. Yields are strong in experienced hands, with indoor harvests commonly landing around 500–650 g/m² under high-intensity LED or HPS. Outdoors in favorable climates, 600–1000 g per plant is achievable with large root zones and full-season sun. Plants tend to reach 120–180 cm indoors and can exceed 200–300 cm outdoors without training.
Vegetative growth benefits from topping at the fourth or fifth node, followed by low-stress training to encourage a flat canopy. A SCROG net helps counter the sativa stretch, allowing even light distribution and higher bud-site density. Expect a 1.5x to 2.5x stretch after flip, so plan vertical space accordingly. Because Haze-line plants can push quickly toward the light, consider early tie-downs and canopy management to prevent light burn.
Lighting targets that work well include a PPFD of 400–600 µmol/m²/s in late veg and 700–900 µmol/m²/s in mid to late flower. Daily light integrals around 35–45 mol/m²/day in veg and 40–55 mol/m²/day in flower are solid baselines. Growers using CO2 enrichment to 1200–1400 ppm can push PPFD to 900–1100 µmol/m²/s if environmental controls are dialed. The cultivar tolerates high light but will show stress in the form of leaf tacoing and top bleach if intensity or canopy temperatures are not managed.
Feed Amnesia moderately, keeping EC around 1.5–1.8 in mid flower and 1.8–2.0 at peak, tapering late to avoid salt buildup. In soil, aim for pH 6.2–6.7; in coco or hydro, 5.8–6.2 is ideal. A balanced 3-1-2 NPK in veg keeps growth lush without excess nitrogen, and a 1-2-3 tilt in flower emphasizes phosphorus and potassium for dense floral clusters. Calcium and magnesium demand is steady; supplementing 100–150 ppm Ca and 50–75 ppm Mg is often beneficial in coco.
Environmental targets include 24–28°C days and 18–22°C nights, with relative humidity at 55–60% in late veg. In early flower, maintain 45–50% RH, then step down to 40–45% in late flower to tighten buds and deter pathogens. VPD ranges of 1.1–1.3 kPa in veg and 1.3–1.5 kPa in flower help maintain steady transpiration and nutrient uptake. Strong, laminar airflow above and below the canopy is key, especially as colas lengthen.
Because Haze lines can be sensitive to overfeeding and intense light at the canopy top, watch for tip burn and light stress early. Anecdotes from Amnesia Haze grows note tall plants requiring tie-downs and occasional light burn when tops get too close to fixtures. The lesson carries over to Amnesia: keep a consistent canopy height and avoid last-minute stretch into the lights. If needed, supercrop pliable stems just before week two of flower to redistribute height.
Training is highly recommended. Topping, LST, and SCROG produce the most consistent results and maximize yield per square meter. In larger rooms, a double-layer trellis system prevents lodging and helps position colas optimally. Defoliate modestly around week three of flower to open interior bud sites, then again lightly at week six if necessary to improve airflow.
In soil, 11–20 L containers offer a good balance between root mass and turnaround time. Coco in 3–5 L pots on frequent fertigations can increase oxygen to roots, often boosting yield by 10–20% compared to soil. Drench volumes should be sized to achieve 10–20% runoff, maintaining stable root-zone EC. Avoid letting coco dry down fully; maintain a consistent moisture rhythm to prevent nutrient swings.
Amnesia shows solid resistance to bud rot due to its moderately open structure, but its longer flowering period still requires vigilance. Powdery mildew can threaten if humidity and airflow slip, especially in cool, stagnant corners. Incorporate an IPM program with weekly scouting, sticky cards, and preventative biologicals like Bacillus subtilis and Bacillus amyloliquefaciens. Predatory mites such as Neoseiulus californicus can provide a safety net against spider mites in warm rooms.
Harvest timing typically falls between day 63 and day 77 of 12/12, depending on phenotype and desired effect. For a bright, zesty head, many growers chop around 5–10% amber trichomes, predominantly cloudy. Flushing for 7–10 days in inert media or tapering feed to low EC in living soil improves burn and flavor. A 10–14 day dry at approximately 60°F and 60% RH, followed by a 4–8 week cure, preserves the citrus-spice signature.
Outdoors, Amnesia prefers warm, Mediterranean-like climates with harvests in mid to late October at latitudes around 40–45°N. Greenhouses extend the viable window and protect against autumn rains, which can otherwise pressure late flowers. Train early with wide-angled ties to maximize light penetration and wind resilience. Organic mulches, living cover crops, and silica supplementation can bolster stem strength and drought tolerance.
Cloning success rates of 85–95% are typical when cuttings are taken from healthy mothers 10–14 days after a light pruning. A mild rooting gel around 0.3% IBA, 18–24°C root-zone temperature, and 75–85% humidity produce roots in 7–12 days. Mothers require periodic pruning to contain sativa vigor; maintain them under 18/6 with moderate feed to prevent lanky stretch. Rotate mother stock to avoid long-term drift and maintain vigor.
For extractors, Amnesia’s resin heads wash decently in ice water, with 4–6% yields from whole flower and higher from select sugar trim. Solventless rosin pressing at 180–200°F for 60–120 seconds often produces a golden sap with intense lemon-spice aromatics. Hydrocarbon runs can return 18–25% depending on biomass quality and cut. Across methods, a careful cold chain from chop to cure retains the top notes that define Amnesia’s appeal.
