Amnesia is a sativa-leaning classic bred by HY-PRO Seeds, the Dutch house that later rebranded as Super Strains. In Europe—especially the Netherlands and Spain—Amnesia has been a dispensary and coffeeshop staple for more than two decades. It is renowned for strong cerebral lift, a pronounced sense of mental clarity, and an unmistakable Haze-forward bouquet.
Growers and consumers often encounter the “Core Cut,” a widely circulated European clone that defines the modern Amnesia profile. While related to the broader Haze family, Amnesia is distinct from Amnesia Haze, a separate but similarly uplifting cultivar. Both share invigorating, euphoric qualities, but Amnesia typically emphasizes brisk mental stimulation and a zesty, incense-like terpene footprint.
Contemporary lab data and market listings consistently describe Amnesia as high in THC with minimal CBD. Leafly’s strain descriptions for Amnesia note uplifting, creative, and euphoric effects in line with a classic daytime sativa. This potency and mood-forward experience explain its enduring popularity among artists, professionals, and consumers seeking focus without heavy sedation.
Historical Context and Breeding Origins
Amnesia emerged from the late-1990s/early-2000s Dutch breeding wave that pushed Haze-dominant plants into mainstream coffeeshop menus. HY-PRO Seeds, later known as Super Strains, is credited with stabilizing the cut that would become “Original Amnesia.” This breeder’s version proliferated quickly in the Netherlands, catalyzed by robust yields, a strong terpene signature, and a lively headspace ideal for social settings.
As the Haze family gained global appeal, Amnesia helped define the European sativa market alongside other legends. Although sometimes conflated with Amnesia Haze, Amnesia remains its own lane in both growth pattern and sensory profile. The strain’s reputation spread as coffeeshops labeled their most energetic offerings under the Amnesia banner, making it a byword for classic, uplifting Dutch sativas.
By the mid-2000s, Amnesia cuttings and seeds circulated widely across Spain’s club scene and into broader European hobbyist circles. The cultivar’s performance in hydroponic systems and under high-intensity lighting made it a favorite among production growers. Feminized offerings—often promoted by Super Strains and other seed houses—made access easier, further cementing the variety’s consistency across grows.
Today, Amnesia is a benchmark reference for modern Haze-influenced sativas: fast-hitting, zestily aromatic, and highly resinous. Its cultural footprint is visible in a long list of hybrids carrying the “Amnesia” name. Even in markets flooded with dessert-terp hybrids, Amnesia retains a loyal following for its clean, energetic lift and commanding nose.
Genetic Lineage and Known Phenotypes
Amnesia’s precise lineage has never been disclosed with rigorous specificity, but breeder notes and grower consensus point to Haze-dominant ancestry with indica support from Afghan genetics. Many experienced cultivators describe it as a Haze cross selected for improved production, shortened flowering compared to pure Haze, and stronger resin output. The result is a phenotype that keeps the Haze uplift while taming the growth cycle just enough for indoor efficiency.
The “Core Cut” is the most referenced phenotype in European circles. It is prized for vibrant lemon-peel and incense aromatics, elongated colas, and a pronounced cerebral onset. This phenotype typically stretches aggressively, foxtails lightly under high light, and packs on a glittering coat of trichomes during weeks 7–11 of bloom.
Seed expressions can vary slightly in stature and terpene balance, with some plants leaning more citrus and others more woody or herbal. Across phenotypes, sativa structure dominates: internodal gaps are moderate, the canopy wants to run upward, and the calyx-to-leaf ratio is favorable for post-harvest trimming. Feminized seeds from Super Strains and other reputable houses target the Core-like chemotype to reduce variability for home growers.
Growers should expect a 150–250% stretch during the first 2–3 weeks of 12/12. Phenotypes that remain compact are comparatively rare and often correlate with slightly denser buds and a marginally shorter flowering time. Tall phenos, by contrast, may finish a week later but can outperform on yield per plant when trained correctly.
Appearance and Bud Structure
Amnesia plants display a classic sativa silhouette with long, flexible branches and upward momentum. Leaves are medium to light green, with slender serrations and a slightly glossy sheen. Colas form as elongated spears that can extend well beyond forearm length when properly trellised.
The buds themselves are lime to forest green with vibrant orange to tangerine pistils. Trichome coverage is heavy, often giving mature flowers a frosted, crystalline appearance under direct light. In high-light environments, gentle foxtailing is common and not necessarily a sign of heat stress.
Calyx stacking is pronounced, contributing to feathery, aerated clusters that resist botrytis better than very dense indica buds. Despite its sativa structure, Amnesia can finish surprisingly solid, especially when day/night temperatures are kept stable. When trimmed, the long calyxes reward the grower with a favorable flower-to-trim ratio that speeds up post-harvest work.
Visually, a well-grown Amnesia stands out in a jar line-up by its radiant trichome sheen and the way light catches on pointed bracts. The flowers are sticky to the touch during late bloom and early cure. Over-dried samples lose some luster, so controlled curing enhances both appearance and tactile appeal.
Aroma and Flavor: Sensory Analysis
Amnesia’s nose is zesty and complex, with lemon zest, sweet citrus candy, and classic Haze incense leading the bouquet. Secondary notes often include fresh cedar, pepper, and a faint herbal anise that lingers after the jar is closed. When ground, the aroma intensifies, releasing sharp terpinolene-driven top notes alongside woody and floral hints.
On the palate, Amnesia is bright and mouth-watering, with a citrus entry that quickly transitions into spiced wood and faint earth. Vaporization preserves a more nuanced lemon-peel and pine profile, while combustion accentuates pepper and incense. The aftertaste clings as a clean, resinous haze that many enthusiasts find unmistakable.
The terpene balance makes Amnesia expressive at even small doses, with terpinolene and limonene often responsible for the high-lift, effervescent character. Caryophyllene contributes a peppery edge that some associate with the “classic Haze tickle” at the back of the throat. Proper curing at 58–62% RH over 3–6 weeks deepens sweetness and rounds the sharper edges.
Freshly dried samples smell more herbal and green, while a mature cure reveals the full citrus-incense duality. In blind tastings, Amnesia is frequently identified by that citrus-wood one-two punch. The flavor holds through the session better than many modern dessert-leaning hybrids, which fade more quickly as the bowl progresses.
Cannabinoid Profile and Potency Data
Amnesia is generally high in THC with very low CBD, matching broader data for Haze-derived sativas. Leafly’s summaries for Amnesia and the closely related Haze family describe high THC and low CBD profiles, with many retail listings showing THC above 20%. It is common to see flower test results in the 18–26% THC range, with CBD often below 1%.
Minor cannabinoids such as CBG and CBC typically register in trace to low single-digit percentages of total cannabinoids. In some phenotypes, CBG sits around 0.5–1.0%, though results vary by lab and cultivation parameters. Total terpene content in well-grown Amnesia often falls between 1.5–3.0% by weight, contributing substantially to the potent sensory and experiential signature.
Consumers frequently report a fast, head-forward onset that aligns with higher THC potency and stimulating terpenes. Because the CBD content is typically low, the psychoactive intensity can feel unbuffered, particularly for newer users. This profile helps explain why some sensitive consumers report anxiety or dizziness at high doses.
For dose planning, a 10–15 mg inhaled THC exposure from Amnesia can feel more intense than the same dose from a beta-myrcene-dominant indica. The terpene matrix likely modulates perceived potency, as suggested by emerging literature on entourage effects. Starting low and titrating up is prudent, especially when trying a new batch or phenotype.
Terpene Profile and Chemovar Insights
Amnesia commonly expresses a terpinolene-dominant chemotype, a hallmark of Haze-family cultivars noted by publications like Leafly in their discussions of “Haze” terpene patterns. Terpinolene contributes bright, piney, and citrusy qualities that many perceive as uplifting and clear-headed. Limonene frequently plays a supporting role, boosting the lemony top note and adding mood-brightening character.
Beta-caryophyllene is a reliable minor player, offering pepper and woody spice while engaging CB2 receptors as a dietary cannabinoid. Ocimene and alpha-pinene often appear as secondary terpenes, lending green, herbal, and forestlike impressions that complement the citrus core. Total terpene levels in the 2% range are common with optimized cultivation and careful post-harvest handling.
Typical Amnesia terpene distribution might fall in the following non-lab-specific ranges: terpinolene as the lead constituent, limonene in a robust secondary position, and caryophyllene, ocimene, or pinene filling out the matrix. Myrcene can be present but tends to be less dominant than in many indica-leaning cultivars. Such a profile maps well to the reported energizing, chatty, and euphoric effects associated with the Haze lineage.
The Haze family’s terpene architecture has been linked informally to the upbeat, creative states consumers seek in daytime strains. In the case of Amnesia, that architecture is especially assertive, making the aroma travel and the flavor persist. This also means preservation of terpenes via cool, slow drying and careful curing has an outsized impact on final quality.
Experiential Effects and Consumer Reports
Consumers describe Amnesia as brisk, uplifting, and cognitively energizing, with quick onset. The headspace tends to be clear yet intensely focused, prompting conversation, brainstorming, and task engagement. Leafly’s description of Amnesia aligns with these anecdotes, emphasizing uplifting, creative, and euphoric effects.
In the broader Haze family, including Amnesia Haze, users often report feeling giggly, euphoric, and talkative, which maps closely to Amnesia’s social-friendly reputation. Side effects in this chemotype can include dry mouth, dizziness, and occasional paranoia, especially at higher doses or in unfamiliar settings. That risk profile is consistent with high-THC, low-CBD sativas known to produce a racy edge in sensitive individuals.
The duration of effect after inhalation commonly runs 2–3 hours, with the peak within the first 45–90 minutes. Muscular relaxation is secondary to cognitive activation, which is why many reserve Amnesia for daytime. Late-evening use can prolong wakefulness in some people, so timing matters.
For dose guidance, a few small puffs are often sufficient for experienced users to reach a creative plateau. Newer users might target 2–5 mg THC equivalent per session and pause to assess, as the terpene-lift can amplify perceived intensity. Many find Amnesia pairs well with music, walking, or light social activity rather than deep relaxation or sleep.
Potential Therapeutic and Medical Applications
While controlled clinical data on a single strain is limited, Amnesia’s user-reported profile suggests utility for low-motivation states and mood flattening. Anecdotes frequently cite improved outlook, enhanced drive, and increased willingness to engage with tasks. For some, this translates into functional daytime relief without heavy sedation.
The limonene- and terpinolene-forward signature may help explain reports of uplift and perceived stress reduction. Limited preclinical and observational research has associated limonene with mood elevation and caryophyllene with potential anti-inflammatory action via CB2 interaction. These findings are not strain-specific but provide plausible mechanisms consistent with user experiences.
Given its high THC and low CBD, Amnesia may not be ideal for anxiety-prone individuals, especially at high doses. Consumers seeking relief from neuropathic pain or depression-like symptoms sometimes prefer stimulating sativas, but the risk of anxiety or paranoia must be weighed. Gradual titration, set-and-setting optimization, and mindful breathing can mitigate edgy moments.
Patients and caregivers should consider chemovar consistency and lab data when selecting Amnesia for therapeutic use. Where available, seek batches with robust terpene totals and verify contaminants are below action limits. As with all cannabis-based interventions, consultation with a knowledgeable clinician is recommended.
Cultivation Guide: Indoors, Greenhouse, and Outdoors
Amnesia behaves like a classic sativa in the garden, with vigorous vertical growth and a prominent stretch during the transition to flower. Indoors, a SCROG or netted trellis is strongly recommended to control canopy height and distribute light evenly. Expect a 10–11 week flowering window for most phenotypes, though some select cuts may finish just shy of 10 weeks in dialed rooms.
Under 12/12, plants can stretch 1.5–2.5x, so flip earlier than you would with compact indicas. Keep daytime temps around 24–27°C and nights at 20–22°C during bloom for resin and terpene development. Maintain relative humidity at 45–55% in early flower and 40–45% from week 5 onward to reduce botrytis risk while preserving aromatic intensity.
Lighting intensity of 600–900 µmol/m²/s PPFD in flower is a sweet spot for most non-CO2 rooms. With supplemental CO2 at 1000–1200 ppm, Amnesia tolerates 900–1100 PPFD if irrigation and nutrition are balanced. Ensure strong, laminar airflow across the canopy to prevent microclimates in the long colas.
In greenhouses and outdoors, Amnesia thrives in Mediterranean-like climates with warm days, cool nights, and low autumn rainfall. Outdoor harvest typically lands in mid to late October in the Northern Hemisphere, depending on latitude and phenotype. Provide sturdy staking or trellis support, as wind can snap the long, cola-laden branches late in the season.
Yield potential is high with proper training and nutrition. Indoors, 450–650 g/m² is realistic under efficient LEDs or HPS with good canopy management. Outdoors, individual plants can exceed 500–800 g each in fertile soil with full sun and adequate water.
Nutrient Management, Training, and IPM
In soil, target pH 6.2–6.7; in coco/hydro, aim for 5.8–6.2 for optimal nutrient uptake. Veg EC of 1.2–1.6 and bloom EC of 1.8–2.2 are typical baselines that can be adjusted by cultivar response. Amnesia appreciates consistent calcium and magnesium, particularly under high-intensity LED lighting.
Nitrogen demands are moderate in veg but taper quickly after week 3 of flower. Excess nitrogen past this point can suppress terpene expression and delay ripening. A bloom booster with phosphorus and potassium is helpful during weeks 4–8, but avoid overfeeding as salt accumulation can invite tip burn.
Training strategies like topping, LST, and SCROG help flatten the canopy and prevent apical dominance. Most growers top once or twice, then weave branches into a net to produce a grid of evenly lit sites. Defoliation is best done in light passes around weeks 3–4 and again near week 7 to open airflow without stripping the plant bare.
Integrated pest management is essential for sativa canopies, which can become humid in their interior. Implement weekly leaf inspections, sticky cards, and rotating biological controls against common pests like spider mites, thrips, and fungus gnats. Foliar sprays are best confined to veg and early preflower; avoid wetting the lengthy colas in mid- to late flower.
Silica supplements can improve stem rigidity, limiting breakage in heavy-yielding phenotypes. Keep irrigation volumes consistent to avoid swings that can stress roots and impact terpene output. Flushing strategies should be tailored to medium and feeding style; in inert media, a 7–10 day final flush can sharpen flavor.
Harvest, Drying, and Curing Best Practices
Amnesia’s peak harvest window is best judged by trichome color rather than breeder week counts alone. For a bright, energetic profile, many growers aim for mostly cloudy trichomes with minimal amber, roughly 5–10%. For a touch more body and longevity, allow 10–15% amber before cutting.
Pre-harvest, a gradual reduction in nitrogen and a steady ramp in potassium can support oil production without sacrificing leaf health. Some cultivators lower night temperatures by 2–3°C in the last week to preserve volatile terpenes. Avoid aggressive defoliation at the end, which can stress the plant and reduce resin density.
Drying should be slow and cool to retain the citrus-incense top notes. Aim for 18–21°C and 55–60% RH with gentle air exchange for 10–14 days until small stems snap cleanly. Rapid drying will mute the lemon and amplify harshness, undermining Amnesia’s signature profile.
Curing in airtight containers at 58–62% RH for 3–6 weeks polishes the flavor and smooths the smoke. Burp jars daily for the first week, then reduce frequency as internal humidity stabilizes. Many find Amnesia’s bouquet fully opens around week three of cure, with the citrus brightening and the incense warming.
Common Pitfalls, Grower Notes, and Troubleshooting
Amnesia can overgrow small spaces if flipped too late, making canopy discipline a recurring challenge. The first two to three weeks of flower define your final height, so plan an early flip or train aggressively preflower. Inadequate trellising leads to collapsed branches when flowers pack on weight.
Reports from growers of Haze-line autos and photoperiods echo that these lines can grow very tall, sometimes requiring tie-downs to keep tops off the lights. Light burn is more likely when tops surge beyond the PPFD sweet spot, particularly under LEDs with intense near-field output. Keep a close eye on top node distance from fixtures and use LST to bend rather than break.
Overfeeding is a common issue; salt buildup manifests as leaf tip burn, curl, and muted aroma. If EC runoff spikes or leaves show clawing, step back on feeding strength and consider a corrective flush in coco/hydro. In soil, top-dressing with balanced amendments and allowing a short reset often restores equilibrium.
Foxtailing can occur from both genetics and excess heat or light. Distinguish genetic foxtails, which are uniform and resinous, from stress foxtails, which look spindly and underdeveloped. If stress-driven, reduce canopy temperature, increase light distance, or adjust intensity to restore normal stacking.
Notable Hybrids and Market Presence
Amnesia’s popularity has spawned numerous hybrids and spin-offs that lean on its citrus-incense charisma. Amnesia Lemon, for example, pulls the zesty side of the profile into an even more lemon-forward experience, while dialing in a relaxing body feel. Crosses like Amnesia x AK-47 aim to balance sativa clarity with hybrid robustness, often moderating flowering time and plant height.
Amnesia Haze, often mentioned alongside Amnesia in consumer guides, is a different cultivar but shares the family’s euphoric, talkative personality. Leafly listings for Amnesia Haze highlight giggly, euphoric, and social effects as well as potential side effects like dry mouth, dizziness, and paranoia, which overlap with reports from Amnesia users. This creates understandable confusion, but both commands strong followings in their own right.
In the European market, Amnesia remains a top-requested sativa due to predictable vigor and a high-value yield-to-quality ratio. Retail menus frequently showcase THC-rich batches with bright, immediately identifiable aroma. For growers, the combination of production scale and strong demand helps explain Amnesia’s enduring presence even as new dessert-terp cultivars cycle through trends.
Seed banks commonly list Amnesia and its feminized versions as “Very High THC” with low CBD, consistent with consumer expectations for a potent daytime option. Where legal testing is available, batches surpassing 20% THC are routine. This potency, alongside the unmistakable bouquet, anchors Amnesia’s commercial longevity.
Final Thoughts
Amnesia exemplifies what many enthusiasts want from a daytime sativa: fast lift, clean focus, and a flavor that turns heads the moment the jar opens. Its Dutch roots with HY-PRO Seeds, later Super Strains, helped define a generation of Haze-forward cultivars in Europe. The strain’s clarity, social spark, and resin production explain both its cultural footprint and its enduring success in grow rooms and shops.
For cultivators, Amnesia rewards canopy discipline, balanced nutrition, and a patient, terpene-preserving dry and cure. When dialed in, the result is a billowing, lemon-incense bouquet and spear-like colas shimmering with trichomes. For consumers, starting low and pacing the session maximizes the bright, creative upside while minimizing the racy edge.
Whether sought as the backbone of a production facility or as a personal daytime favorite, Amnesia delivers a distinctive, data-consistent profile: high THC, low CBD, terpinolene-forward terpenes, and a reliably uplifting effect set. That combination has kept it relevant for decades and continues to win converts among those who value energetic clarity. In a crowded market, Amnesia still feels unmistakably itself—timeless, expressive, and emphatically alive.
