Amnesia Gold is a mostly sativa hybrid bred by Pyramid Seeds, the Spanish seedbank known for high-performance genetics with strong commercial appeal. Reported by the breeder and major retailers as an 80% sativa and 20% indica cross, it merges energizing, cerebral effects with a manageable growth profile. The cultivar has become popular among enthusiasts who enjoy citrus-forward Haze flavors and growers seeking robust yields with a classic sativa high.
In consumer-facing descriptions and grow reports, Amnesia Gold is often highlighted for its bright, lemony terpene profile and lively, euphoric lift. Typical lab results cited by retailers place THC in the high-teens to low-20s percent by dry weight, with very low CBD. This makes the strain squarely psychoactive and better suited to daytime use for experienced consumers.
Pyramid Seeds also offers an autoflowering counterpart, Auto Amnesia Gold, which compresses the growth cycle for faster turnaround and simplified cultivation. While the photoperiod version is the flagship for yield and full expression, the auto has broadened the strain’s accessibility to new growers. Together, these options have helped Amnesia Gold secure a foothold in sativa-focused gardens across Europe and beyond.
History and Breeding
Pyramid Seeds introduced Amnesia Gold to combine the famed Haze headspace with modern vigor and yield. The cross pairs Lennon with Amnesia Haze, leveraging a proven platform to achieve flavor, potency, and stretch control. Their stated outcome is an 80% sativa hybrid that keeps the classic Haze spirit intact while refining growth and harvest metrics for contemporary growers.
The breeder’s decision to include Lennon—a Pyramid Seeds staple—adds structure and speed to what could otherwise be a long-flowering, lanky sativa. Amnesia Haze contributes the well-known citrus, incense, and uplifting drive that made the Amnesia lineage a European staple. The blend aims to balance production value with a bright, heady effect profile prized by sativa devotees.
In the years since release, Amnesia Gold has been taken up by seed retailers that often list it alongside flagships like Amnesia Haze and other Amnesia variants. The strain’s expansion to an autoflower (Auto Amnesia Gold) reflects strong demand for quicker cycles, especially in regions with shorter summers or indoor growers seeking multiple harvests per year. This two-pronged offering—photoperiod and auto—has helped maintain consistent visibility and adoption among both hobbyists and small-scale commercial cultivators.
Genetic Lineage
Amnesia Gold’s lineage is Lennon × Amnesia Haze, as reported by Pyramid Seeds and major retailer listings. Lennon is a Pyramid Seeds hybrid known for its sativa expression, aroma intensity, and resin production, often deployed in crosses to bolster vigor and yield. Amnesia Haze traces to a complex Haze background blended with southeast Asian and possibly Jamaican or Hawaiian influences, recognized for electric cerebral effects and citrus-incense terpenes.
The resulting genotype leans 80% sativa and 20% indica, which aligns with its reported plant architecture and experiential profile. Growers regularly note sativa-like internodal spacing, vigorous apical growth, and extended flowering relative to fast indica lines. However, the indica fraction contributes denser flower formation and a more compact finish than pure Haze progenitors.
From a chemotype perspective, Amnesia-line crosses frequently show terpinolene-dominant terpene profiles with meaningful limonene, myrcene, and beta-caryophyllene support. Amnesia Gold generally conforms to this pattern, with citrus, pine, and herbal-spicy notes that echo classic Amsterdam café Haze experiences. This lineage-focused predictability is a major draw for consumers who favor uplifting, creative daytime cannabis.
Appearance and Morphology
Amnesia Gold typically grows tall and branchy with pronounced apical dominance, a hallmark of sativa-leading hybrids. Internodal spacing is moderate to wide, allowing good airflow but requiring proactive training indoors to control height. Mature plants often display elongated colas with a high calyx-to-leaf ratio, improving trim efficiency and bud presentation.
Flowers are medium-dense for a sativa, reflecting the 20% indica influence that helps stack bracts without compromising resin coverage. Under optimized lighting, buds frost over with a uniform trichome layer, appearing glassy with plentiful capitate-stalked glands. Pistils commonly express bright orange to amber hues near maturity, contrasting against lime-to-forest-green calyxes.
In late bloom, phenotype variations can express slightly different bud shapes, from tapered Haze spears to more chunked, conical colas. Leaf morphology often skews narrow-bladed, helping mitigate humidity issues but increasing the plant’s vertical footprint. Expect significant flowering stretch—often 1.5× to 2.5×—so canopy planning is essential indoors.
Aroma
The aroma of Amnesia Gold is assertive and layered, typically led by citrus-forward Haze notes. Freshly broken buds often release lemon zest, sweet orange, and pine, underpinned by herbal-spicy tones reminiscent of incense. As the flowers cure, many users report deepening sweetness coupled with a peppery, woody backbone.
In terpinolene-leaning phenotypes, expect a bright, almost effervescent character that fills a room quickly. Limonene co-expression accentuates the citrus, while beta-caryophyllene and humulene can add warm spice and subtle earthiness. The net result is a terpene bouquet that skews uplifting and clean, frequently described as “classic Haze with modern polish.”
Growers should anticipate strong odor during mid-to-late bloom, especially in sealed indoor rooms. A well-sized carbon filter and negative pressure are recommended if discretion is necessary. Curing at 60% relative humidity for 10–14 days tends to preserve the high notes while smoothing out any grassy volatiles.
Flavor
On the palate, Amnesia Gold carries over its citrus-forward aroma into a bright, zesty flavor. Lemon peel, sweet orange, and pink grapefruit notes are common on the inhale, with a crisp pine-herbal finish on the exhale. A light sweetness often persists on the tongue, balanced by a peppery tickle that signals beta-caryophyllene presence.
As the cure progresses into weeks three to six, the flavor typically rounds out, reducing any sharp chlorophyll edges. Some phenotypes lean more toward incense and cedar, evoking classic Haze café profiles from the early 2000s. Vaporization at lower temperatures (170–185°C / 338–365°F) can emphasize citrus and floral top notes, while combustion reveals deeper wood and spice.
Overall, Amnesia Gold is considered a flavorful sativa that rewards a careful cure and clean consumption hardware. Users who enjoy terpinolene-forward strains like Jack Herer and traditional Amnesia variants will likely find a familiar flavor footprint. The persistence of citrus and pine across delivery methods makes it a reliable choice for flavor chasers.
Cannabinoid Profile and Potency
Retailers commonly list Amnesia Gold with THC in the 18–22% range by dry weight, though potency can vary by phenotype and cultivation practices. CBD is typically very low, often below 1%, placing it firmly in the THC-dominant Category I chemotype. Minor cannabinoids like CBG and CBC are generally present in trace amounts (<1%), with slight increases possible in longer flowering windows.
This potency places Amnesia Gold among the stronger mainstream sativas, suitable for experienced consumers and measured dosing for newer users. Inhalation onset is usually quick—within minutes—with peak effects arriving around the 20–40 minute mark and tapering over 2–3 hours. Edible preparations can extend the experience substantially, but the low CBD content means effects remain head-centric without much buffer.
For extraction, the strain’s resin output and terpene density can produce flavorful concentrates. However, the terpene profile skews toward more volatile compounds like terpinolene and limonene, which can be lost with aggressive purging. Cold-cure rosin or hydrocarbon extracts processed at lower temperatures may retain the citrus-forward character best.
Terpene Profile and Minor Compounds
Amnesia Gold commonly presents a terpinolene-dominant terpene profile, a hallmark of many Amnesia and Haze descendants. In third-party analyses of terpinolene-leading cannabis, terpinolene can constitute 15–40% of the total terpene fraction, with limonene, myrcene, and beta-caryophyllene following in the mid-to-low single digits. While specific lab percentages vary by cut and environment, this distribution aligns with the cultivar’s reported lemon-pine-incense bouquet.
Supporting terpenes often include ocimene and humulene, contributing sweet herbal and woody notes, respectively. Linalool may appear at trace levels, softening the profile with a faint floral edge in some phenotypes. The interplay of terpinolene and limonene is largely responsible for the strain’s sparkling, uplifting aroma and perceived mood-elevating potential.
Beyond terpenes, flavonoids such as cannflavins A and B are likely present at low concentrations, though these are seldom quantified in retail testing. Minor cannabinoids like CBG can hover around 0.1–0.5% in some harvests, especially if taken slightly earlier or later than the peak THC window. Collectively, these compounds form an ensemble that supports the cultivar’s bright sensory signature and energetic feel.
Experiential Effects
Consumers typically describe Amnesia Gold as clear-headed, energetic, and uplifting, aligning with its 80% sativa heritage. Early onset often brings a mood lift and heightened sensory acuity, with many users reporting increased motivation and talkativeness. The experience can feel distinctly cerebral, emphasizing creative ideation and a buoyant sense of focus.
Physically, the strain tends to be light and functional, with minimal body heaviness compared to indica-leading hybrids. That said, higher doses can become racy for sensitive individuals, potentially provoking short-lived anxiety or a fluttery heart sensation. Responsible dosing—especially for newer users—helps maintain a productive and enjoyable arc.
Duration typically spans 2–3 hours for inhaled routes, with a smooth decline rather than a heavy crash. The mood elevation makes it popular for daytime tasks, brainstorming, or social settings where conversation flows. As with many terpinolene-forward cultivars, pairing the strain with hydration and light snacks can reduce occasional cottonmouth or mild dry eye.
Potential Medical Uses
While formal clinical trials on Amnesia Gold are not published, its THC-dominant, terpinolene-forward profile overlaps with strains used anecdotally for mood and energy. Patients report potential benefits for low motivation, mild-to-moderate depression, and fatigue, particularly in the first 60–90 minutes after dosing. The uplift and focus may also assist with attention-related challenges in low-to-moderate doses, though overstimulation is possible at higher intakes.
Some users cite transient relief from tension headaches or stress-induced muscle tightness, perhaps due to distraction and perceived relaxation rather than sedative action. However, those prone to cannabis-induced anxiety should proceed cautiously, titrating small doses to avoid racing thoughts. The low CBD content means less counterbalance to THC’s psychoactivity, so medical users seeking anxiolytic support may consider pairing with CBD or choosing a more balanced cultivar.
For appetite, reports vary; the strain is not consistently munchie-inducing compared to myrcene-heavy indicas, but some users experience moderate appetite stimulation. Nausea relief may occur for certain patients, especially with fast-acting inhaled routes. As always, medical use should be discussed with a qualified clinician, and legality and dosing guidelines should be followed in the patient’s jurisdiction.
Comprehensive Cultivation Guide
Legal note: The following cultivation information is provided for readers in regions where home growing is legal and compliant with local regulations. Always follow applicable laws. Growing conditions and results can vary significantly by environment, phenotype, and grower skill.
Genotype and growth summary: Amnesia Gold is an 80% sativa strain (Lennon × Amnesia Haze) from Pyramid Seeds with vigorous vertical growth and a pronounced flowering stretch. Indoors, plan for 1.5× to 2.5× stretch after flip, setting the stage for training early in veg. The breeder’s autoflower variant, Auto Amnesia Gold, provides a fast alternative for small spaces or rapid turnover.
Flowering time and harvest window: Reported indoor flowering time for the photoperiod version commonly falls in the 65–75 day range from the onset of 12/12. Outdoor harvest in temperate zones typically lands from early to mid-October in the Northern Hemisphere, depending on latitude. Autoflowering versions can finish in roughly 70–85 days seed-to-harvest, allowing multiple outdoor runs in warm seasons or fast indoor cycles.
Yield expectations: Under optimized indoor conditions with high-intensity lighting, growers routinely report 500–600 g/m², with experienced cultivators occasionally exceeding this via ScrOG and supplemental CO2. Outdoors, well-managed plants in fertile soil can produce 400–800 g per plant, with 1 kg+ possible in long-season, high-sun environments. Autos seldom match photoperiod yields but are often harvested at 60–120 g/plant indoors and 80–180 g/plant outdoors, depending on pot size and season.
Lighting and DLI: As a sativa-leaning hybrid, Amnesia Gold thrives under strong light. Target a daily light integral (DLI) of 35–45 mol/m²/day in veg and 40–55 mol/m²/day in flower when using LEDs; this corresponds to roughly 500–900 µmol/m²/s PPFD over a 12-hour photoperiod. If adding CO2 (1000–1200 ppm), PPFD can be pushed toward 900–1100 µmol/m²/s in mid-late bloom with careful temperature and VPD management.
Environment and VPD: Aim for 24–28°C (75–82°F) daytime and 18–22°C (64–72°F) nighttime temperatures. Relative humidity should sit near 60–70% in seedlings, 50–60% in veg, 45–55% in early flower, and 40–50% in late flower to limit botrytis risk. Maintaining vapor pressure deficit (VPD) around 0.9–1.2 kPa in veg and 1.2–1.4 kPa in bloom supports strong gas exchange and terpene retention.
Substrate and pH/EC: In soil, keep pH between 6.2 and 6.8; in coco/hydro, 5.8 to 6.2 is ideal. Electrical conductivity (EC) in coco/hydro commonly ranges 1.2–1.6 mS/cm in veg, 1.6–2.0 mS/cm in peak bloom, tapering during ripening. For soil, feed according to runoff EC and plant response, as pre-amended mixes and microbial activity can alter availability.
Nutrition strategy: Sativa-leaning plants often prefer a steady, moderate nitrogen supply in veg, transitioning toward higher potassium and adequate phosphorus in bloom. A common ratio progression is N-P-K around 3-1-2 in veg, shifting to about 1-2-3 by mid flower, with emphasis on calcium and magnesium throughout. Supplementing silica (e.g., 50–100 ppm) can strengthen stems on this stretchy cultivar and improve stress tolerance.
Irrigation cadence: In coco, frequent fertigation (1–3 times daily) at 10–20% runoff supports consistent EC and pH, especially under high light. In soil, allow wet-dry cycling without letting pots remain waterlogged; sativa roots appreciate oxygenation. Smart pots or fabric containers (3–7 gallons indoors, 10–50+ gallons outdoors) can enhance root-zone aeration and growth rates.
Training and canopy control: Early low-stress training (LST) and topping at the 4th–6th node keep the canopy even before flip. ScrOG is highly effective—spread branches to maximize light capture and control stretch in the first 2–3 weeks of 12/12. Defoliation should be moderate; remove large fan leaves blocking sites, but avoid heavy stripping on sativa phenotypes that can stress more easily.
Plant spacing and support: Indoors, 1–4 plants per square meter work well depending on training style—ScrOG and mainline growers can succeed with fewer, larger plants. Install trellis netting before flip to prevent late flower sagging on long colas. Outdoors, provide sturdy stakes or cages, as wind can stress lanky branches.
Pest and disease management: Sativa morphologies can resist bud rot better than dense indicas, but Amnesia Gold’s large colas still require airflow. Maintain oscillating fans, prune larfy interior shoots, and keep RH in range to prevent botrytis and powdery mildew. Integrated pest management (IPM) with beneficials like Encarsia for whitefly or Phytoseiulus for spider mites, combined with preventative neem or botanical oils in veg, reduces pressure without harsh residues.
CO2 enrichment: If your room is sealed and climate-controlled, enriching to 1000–1200 ppm CO2 can boost photosynthesis and yield by 10–20% when paired with high PPFD and optimal nutrition. Increase irrigation frequency accordingly, as transpiration and nutrient uptake rise under CO2. Always prioritize safety—monitor CO2 with alarms and ensure intake/exhaust protocols match local codes.
Flowering stretch management: Expect 1.5× to 2.5× expansion in the first 2–3 weeks after flip. To manage, lower canopy height pre-flip, run a slightly cooler night differential, and consider a brief blue-leaning spectrum in early bloom to temper internodal elongation. Mechanical support through trellis is essential to preserve bud structure and prevent lodging.
Ripening cues and harvest timing: Evaluate trichomes with a jeweler’s loupe—many growers target mostly cloudy with 5–15% amber for a lively, euphoric effect. Pistils will turn from white to orange/brown and retract toward the calyx as maturity approaches. If flavor is a priority, avoid pushing too far into amber, as oxidized terpenes can dull citrus top notes.
Flush and finish: In inert media like coco, a 7–10 day flush with properly pH’d water or a light finishing solution can improve burn and flavor. In living soil, reduce feed and rely on soil biology, avoiding a hard flush that can disturb the rhizosphere. Gradual tapering prevents abrupt senescence that might stall resin maturation.
Drying and curing: Target 10–14 days of drying at 18–20°C (64–68°F) and 55–60% RH with gentle airflow and minimal direct breeze on flowers. Once stems snap rather than bend, jar the buds with hygrometers and maintain 58–62% RH, burping daily for the first week and then weekly for 3–4 weeks. Properly cured cannabis stabilizes around 10–12% moisture content; water activity near 0.55–0.65 supports shelf stability and terpene preservation.
Post-harvest quality and storage: Store in airtight, light-proof containers at cool temperatures (ideally 15–20°C / 59–68°F). Exposure to heat, oxygen, and UV accelerates THC degradation to CBN and terpene evaporation; studies suggest significant monoterpene loss can occur within weeks under poor storage. With good storage, flavor remains vibrant for months, and perceived potency stays closer to harvest levels.
Outdoor considerations: In Mediterranean-like climates, Amnesia Gold can reach 2–3 meters with ample root volume and full sun. Choose a site with 8+ hours of direct light, well-drained soil, and wind protection, and amend with compost plus slow-release organics. In humid regions, prioritize cultivars with airier buds or implement aggressive canopy management and preventative biofungicides.
Autoflower variant (Auto Amnesia Gold): The auto version is reported to grow fast with a total cycle of roughly 10–12 weeks from seed, producing a similar citrus-forward terpene profile. Plant autos in their final container (e.g., 3–5 gallons) to avoid transplant shock and maintain 18–20 hours of light daily. Gentle LST is preferred over topping, and consistent, moderate feeding avoids stalling the short vegetative window.
Common mistakes and troubleshooting: Over-veg indoors without a training plan can cause light burn and height issues after flip—keep a close eye on canopy distance. Excess nitrogen late in flower can suppress terpene brightness and prolong ripening; taper N by week 4–5 of bloom. If aromas seem muted, review dry/cure conditions and ensure temperatures stayed below 21°C (70°F) and RH between 55–60% to protect monoterpenes.
Benchmark metrics at a glance: Many growers aim for 1–2 grams per watt under efficient LEDs, translating to 500–700 g/m² in dialed-in rooms. Indoors, finished plant heights of 80–140 cm are typical with training, while outdoor specimens can exceed 200 cm with ease. Potency commonly tests in the 18–22% THC band, with CBD <1% and terpinolene leading the terpene fraction in most phenotypes.
Sustainability pointers: Use high-efficiency LEDs (2.5–3.0+ µmol/J) to reduce energy costs and heat load. Recycle coco or build living soil to minimize waste, and consider closed-loop irrigation to cut water use by up to 30–50%. Integrated biological controls and targeted IPM reduce reliance on synthetic pesticides, protecting both consumer safety and beneficial insects.
