Amnesia Platinum is a mostly sativa cultivar developed by Bulk Seed Bank as a refined, frost-heavy interpretation of the iconic Amnesia family. It retains the cerebral spark and high-energy tempo that made Amnesia a European coffee shop staple, while leaning into a platinum-grade trichome coverage that appeals to modern connoisseurs and extractors. Expect a bright, uplifting experience with a terpene palette anchored in citrus, pine, and spice, and a potency window that comfortably competes with top-shelf sativas.
In market terms, Amnesia descendants are consistently categorized as high THC and low CBD chemovars, a pattern mirrored here. Leaf data for the broader Amnesia family indicates uplifting, creative, and euphoric effects are among the most commonly reported, with CBD typically well below 1% and THC often cresting above 20%. Amnesia Platinum follows that trend while embracing the clarity and drive sativa enthusiasts seek, especially for daytime use.
The platinum moniker signals extraordinary resin density, translating to a shimmery, almost metallic frost on cured flowers. This resin-forward profile is not just cosmetic; it supports strong aromas, assertive flavor, and above-average returns in solventless or hydrocarbon extraction. For growers and consumers alike, Amnesia Platinum sits at the intersection of classic Haze excitement and contemporary potency expectations.
Bulk Seed Bank positions this cultivar for reliability alongside potency, a balance many Haze-leaning lines struggle to achieve. With prudent training and dialed environmental controls, growers can manage classic sativa stretch while capturing heavy yields in the 500–650 g/m² indoor range. For outdoor cultivators in warm, dry climates, single plants can finish large and weighty when allowed extended vegetative growth and robust trellising.
Breeder Background and Strain History
Bulk Seed Bank is known for preserving and refining widely admired European genetics, packaging them for growers who want stable, high-performance seed lines. Amnesia Platinum reflects that ethos by polishing an already beloved lineage into something remarkably crystalline and commercially friendly. The breeder has not published a precise parental recipe, but the aim is clear: a streamlined Amnesia expression with boosted resin and a consistent flowering window.
The Amnesia name traces back to Dutch breeding circles of the 1990s and early 2000s, where Haze-centric hybrids defined the cerebral side of the coffee shop scene. Whether encountered as Amnesia, Amnesia Haze, or house-named cuts, the throughline was always sativa lift, neon citrus aromatics, and pronounced euphoria. By the mid-2010s, numerous seed companies offered their take on the archetype, responding to ongoing demand for energetic sativas that contrasted the OG Kush wave.
Amnesia Platinum enters that continuum as a modernized, frost-forward phenotype. Where classic Amnesia sometimes leaned wispy in bag appeal, this platinum version emphasizes dense trichome blankets and more uniform bud structure when dialed in under high-intensity lighting. The goal is to preserve the legendary head while offering a 21st-century finish that looks and tests like top-shelf.
In consumer perception, the Amnesia archetype is synonymous with creativity and mood elevation. Leaf-based overviews for Amnesia highlight uplifting, creative, and euphoric effects, with relatively minimal CBD moderation. Amnesia Platinum speaks to that reputation, maintaining a bright, fast-onset ride that suits daytime tasks, brainstorming, and social sessions.
Genetic Lineage and Sativa Heritage
While Bulk Seed Bank does not disclose exact parents for Amnesia Platinum, the chemotype and sensory signatures point to the Haze family as its backbone. Historically, Amnesia lines descend from Haze hybrids that may include Thai, Jamaican, South Indian, and occasionally Afghani influences for structure and finish. These Haze-centric pedigrees tend to produce terpinolene-forward terpene profiles alongside limonene, ocimene, and alpha-pinene, all of which are consistent with Amnesia Platinum’s aroma.
Many Dutch-style Amnesia cuts also show hints of Skunk and Afghan heritage, likely introduced to tighten internodes and wrap up flowering within 9–11 weeks. That combination helps explain the cultivar’s balance of stretch, cola length, and ultimately respectable density when properly managed. The result is a mostly sativa plant that can still finish commercially indoors without pushing into extremely long flowering periods.
Looking across sibling lines and derivatives, the family resemblance is strong. Even products like Amnesia x AK-47 are commonly described with overlapping flavor notes such as citrus, lemon, pine, pungent, spicy, sweet, and woody. Amnesia Platinum slots squarely in that spectrum, favoring citrus-pine lift with a dry, peppery finish that hints at beta-caryophyllene.
Chemically, these sativa-leaning Hazes often carry total terpene content in the 1.5–3.0% range, with terpinolene frequently leading the pack. When terpinolene heads the profile, users commonly report an energizing headspace relative to myrcene-dominant cultivars, which helps explain Amnesia Platinum’s reputation for daytime clarity and momentum. A minor Afghani or Northern Lights contribution, if present, would largely serve to stabilize morphology and resin output rather than steer the overall effect toward sedation.
Appearance and Bud Structure
True to its name, Amnesia Platinum often appears dusted with a near-silver sheen of glandular trichomes. Under magnification, heads are generously proportioned and densely packed, an advantage for both bag appeal and extraction. The calyxes tend toward lime-to-forest green, with orange to tangerine pistils that weave through the canopy.
Sativa influence shows in the plant’s architecture, especially during early bloom when vertical stretch can reach 150–200% of pre-flip height. With training, growers can encourage long, stacked colas that harden up well in weeks 7–10, especially under strong PPFD and optimized vapor pressure deficit. Well-run canopies display a pleasing ratio of calyx to leaf, easing trim work and improving the final jar look.
Mature buds balance classic Haze lance shapes with a more modern density than some legacy cuts. In drier climates or rooms with excellent airflow, the resin wraps these spears with a sparkling coat that earns the platinum tag. When dried and cured correctly, you can expect a taut, slightly sticky feel and a break that reveals bright green interiors dusted with frosty white.
Handled carelessly, sativa buds can fox-tail, but that tendency is mitigated when heat and light intensity are not excessive late in flower. Keeping canopy tops below ~28–29°C in late bloom and maintaining targeted VPD helps preserve tight calyx stacking. The result is a nug that looks boutique while staying true to its airy, uplifting lineage.
Aroma: Citrus, Pine, and Spice
Open a jar of Amnesia Platinum and the first impression is a citrus-led brightness that often reads as lemon zest with a splash of sweet orange. A piney undertone follows, evoking fresh-cut wood and conifer needles, especially when buds are broken apart. Spice threads through the background, with dry pepper and a faint herbal edge that nods to Haze ancestry.
When ground, the bouquet intensifies in the citrus and pine registers while releasing a slightly sweet, floral top note. This is consistent with terpinolene and limonene leadership supported by alpha-pinene and ocimene, a quartet typical of lively sativas. The spice dimension, often linked to beta-caryophyllene and humulene, tends to sharpen on the nose just before consumption.
Storage conditions heavily influence aromatic fidelity, as citrus-forward terpenes are among the most volatile. Kept around 62% relative humidity in airtight, UV-protected containers, the profile remains vivid for months. Heat spikes or repeated exposure to air can flatten the citrus within weeks, shifting the nose toward wood and pepper.
Compared to related offerings, such as Amnesia x AK-47, the Platinum cut stays firmly on the citrus-pine axis rather than the deeper woody-earth spectrum. Users who crave a bright, invigorating scent profile will find it consistently satisfying. The aroma signals the experience: a clean, zesty lift with structured focus.
Flavor and Combustion Characteristics
The flavor tracks closely with the nose, opening on inhalation with sweet lemon and a crisp, sap-like pine. As the draw deepens, subtle floral notes appear, accompanied by a dry pepper snap on the exhale. That peppery edge lingers, giving the finish a sophisticated, adult bitterness that balances the sweetness.
Combustion quality is typically smooth when flowers are properly flushed and cured for at least 2–4 weeks. In joints, the smoke reads clean and buoyant, with a white-to-light-gray ash indicating minimal residuals. In glass or convection vaporizers set around 180–195°C, citrus and pine flavors stand out, while higher temps bring in more earthy spice and a faint woody resin quality.
For rosin or live resin, the citrus fraction is especially pronounced, often reminiscent of lemon peel with a faint candy brightness. Pine reasserts on exhale, and caryophyllene-derived spice becomes more apparent with successive pulls. Consumers who appreciate bold, delineated flavor transitions will find Amnesia Platinum both articulate and repeatable across devices.
Frequent tasters note low flavor fatigue compared to heavily sweet cultivars. The crisp pine and pepper keep the palate engaged, even across longer sessions. This is a practical benefit for daytime consumers who microdose frequently and value a profile that stays appetizing.
Cannabinoid Profile and Potency
Amnesia Platinum follows the Amnesia family trend of high THC with minimal CBD. In contemporary markets, similar Haze-centric sativas commonly test between 18–26% THC by dry weight, with top phenotypes occasionally surpassing 27% under optimized conditions. CBD typically registers under 0.5%, often below 0.2%, reinforcing a strongly psychoactive, minimally moderating profile.
Translating percentages to mg/g, a 22% THC flower carries roughly 220 mg of THC per gram of dried material. After decarboxylation, that potential becomes more fully psychoactive, which is relevant for edibles or infusions derived from this cultivar. CBG is often present in trace-to-moderate quantities, frequently 0.2–1.0%, adding a subtle layer that some users describe as focus-supportive.
Consistency depends on cultivation practices, harvest timing, and post-harvest handling. Light intensity, temperature control, and cure discipline can swing potency by several percentage points between runs. With strong horticultural discipline, it is realistic to expect repeatable lab results within ±2–3% THC across cycles.
Inhalation onset is rapid, frequently within 2–5 minutes, with peak effects settling by 10–20 minutes. Duration generally runs 2–3 hours for regular consumers and can extend longer for low-tolerance users. This time course reflects typical inhalation bioavailability for THC, which literature places in the 10–35% range depending on device, technique, and individual physiology.
Terpene Profile and Chemovar Insights
While individual labs will vary, Amnesia Platinum commonly expresses a terpinolene-led terpene profile supported by limonene, myrcene, and alpha-pinene. Beta-caryophyllene, humulene, and ocimene often appear as meaningful contributors, with linalool and nerolidol present in trace amounts. Total terpene content is typically in the 1.5–3.0% range for well-grown flower, which is robust enough to deliver strong aroma and flavor.
Estimated relative contributions frequently look like this: terpinolene 0.3–1.0%, limonene 0.2–0.6%, myrcene 0.2–0.5%, alpha-pinene 0.1–0.3%, and caryophyllene 0.1–0.4%. Ocimene and humulene often land in the 0.05–0.2% range each, with minor variability from environment and phenotype. These values are representative of many Haze-influenced sativas and align with the citrus-pine-spice bouquet users report.
Terpinolene-forward chemistry aligns with subjective reports of energy, creativity, and mental brightness. Limonene contributes mood elevation and citrus snap, while alpha-pinene is associated with a perceived sense of clarity and alertness. Myrcene, although present, is not usually dominant here, which helps prevent the profile from leaning sedative.
Growers can subtly shift terpene expression by managing late-flower temperatures and light intensity. Keeping canopy temperatures in the 24–27°C range during the final two weeks and avoiding excessive PPFD above ~1000–1100 can help preserve volatile monoterpenes. A gentle, slow cure at 60–62% RH protects terpenes over time, sustaining both the citrus zip and pine backbone.
Experiential Effects and Onset–Duration
Amnesia Platinum is best described as bright, fast, and mood-elevating, consistent with broader Amnesia data that highlights uplifting, creative, and euphoric effects. There is a motivated, forward-drive sensation within the first 10–15 minutes that suits task-oriented use. Many users report conversational ease, enhanced ideation, and a clean focus that avoids fogginess.
Body effects are secondary but present, typically as a light, buoyant relaxation without couchlock. The comedown often lands soft, with a gentle return to baseline rather than a hard crash, especially at moderate doses. At higher doses, particularly for low-tolerance users, a racy edge can surface, so conservative titration is wise.
Onset with inhalation is rapid, frequently in 2–5 minutes, with peak subjective intensity by 10–20 minutes. Functional duration is roughly 120–180 minutes, though residual afterglow can extend beyond that. Edible preparations will shift these timelines substantially, with onset in 30–90 minutes and peak effects often at 2–3 hours post-ingestion.
Compared to grounding, myrcene-heavy cultivars, Amnesia Platinum is distinctly cerebral and kinetic. It invites daytime use, brainstorming, and creative projects, mirroring the general Amnesia reputation noted by Leaf sources for high THC and low CBD. It is not inherently sedating, making it a poor fit for insomnia but an excellent option for afternoon ambition.
Potential Medical Uses and Considerations
Consumer and patient feedback often points to mood support as a primary use case, congruent with the Leafly overview that places the broader Amnesia family in uplifting, euphoric territory. Individuals describing low mood, stress, or anhedonia often report a noticeable brightening and increased engagement within minutes of inhalation. The clarity reported by many users can also be helpful for focus-oriented tasks when sedation would be counterproductive.
Appetite stimulation is variable but present for some, with a modest increase in hunger in the mid-to-late phase of the experience. For those managing fatigue, the energizing tilt can be a benefit during daytime responsibilities. Conversely, those prone to anxiety may find large doses overstimulating, so incremental titration is recommended.
From a pharmacokinetic standpoint, inhalation offers fast relief windows that can be more predictable for situational stress or mood dips. For medical users, starting with very small inhaled doses of 1–2 mg THC equivalent and working upward allows careful assessment of sensitivity. Oral formats derived from Amnesia Platinum will have slower onset and stronger body persistence, which can be helpful for extended coverage but requires patience to avoid overconsumption.
As with any high-THC, low-CBD cultivar, there is minimal cannabidiol buffering to temper intensity. Users sensitive to THC may consider pairing with a CBD product to moderate the experience. None of the above constitutes medical advice, and patients should consult a healthcare professional, particularly if they have cardiovascular conditions, a history of panic, or are taking medications with potential interactions.
Comprehensive Cultivation Guide: Environment and Lighting
Amnesia Platinum thrives in a slightly warm, well-ventilated environment with strong light intensity. In vegetative growth, target 24–26°C with relative humidity of 60–70% and a VPD of roughly 0.8–1.1 kPa. In flowering, aim for 24–27°C by day and 20–22°C by night, with RH stepping down to 45–55% in early bloom and 40–50% in late bloom to protect resin and prevent botrytis.
Sativa stretch is significant, commonly 150–200% after the flip. To manage canopy height, flip to 12/12 earlier than you would with compact indicas and anticipate the need for trellising or stakes by week 2–3 of flower. Topping and low-stress training in early veg can help construct an even, multi-top canopy that keeps apical dominance in check.
Lighting intensity drives resin and density for this platinum phenotype. In veg, deliver 400–600 PPFD with an 18/6 photoperiod to encourage robust root and node development. In flower, 700–1000 PPFD is a productive target for most rooms; experienced growers with CO2 supplementation at 900–1200 ppm can push up to ~1100–1200 PPFD provided heat management and VPD are dialed.
Expect a flowering window of 9–11 weeks depending on phenotype, environment, and desired effect. Early-harvested plants at ~9 weeks often exhibit a racier head and sharper citrus, while 10–11 weeks deepens the body tone and spice while slightly taming the edge. Track maturity via trichomes, aiming for mostly cloudy with 5–10% amber for a balanced effect profile.
Soilless media such as coco coir enable tight steering of feed and irrigation, while high-quality living soil can deliver excellent terpene expression with lighter management. pH ranges of 6.2–6.8 in soil and 5.7–6.2 in hydro/coco will keep nutrient uptake efficient. Provide assertive airflow across and through the canopy to cool leaf surfaces and preserve delicate terpenes.
Comprehensive Cultivation Guide: Nutrition, Training, and Irrigation
This cultivar appreciates a steady nitrogen supply in veg, transitioning to a phosphorus- and potassium-forward diet in bloom. In coco or hydro, an EC of 1.2–1.4 in veg and 1.6–2.0 in mid-to-late flower is a solid baseline, with experienced growers occasionally pushing to 2.1–2.2 if plants are thriving. Cal-mag support at 100–150 ppm Ca and 40–60 ppm Mg is often beneficial, particularly under LED lighting.
Silica supplementation at 40–60 ppm can strengthen cell walls and help support long colas, reducing flop during late bloom. Sulfur and magnesium, often delivered via Epsom salts, can enhance terpene biosynthesis when applied judiciously. Avoid overfeeding nitrogen after week 4 of flower, as excess N can blunt terpene intensity and slow ripening.
Training should begin early. Top once or twice by week 3–4 of veg, then deploy low-stress training to spread branches and open the interior. A single trellis net installed before stretch and a second net by week 3–4 of flower offer reliable lateral support for this sativa-leaning architecture.
Irrigation frequency will vary with container size and media, but sativa roots prefer oxygen-rich conditions. In coco, many growers find success with 2–5 small irrigations per light cycle to 10–20% runoff, keeping media EC stable and roots highly aerated. In soil, water to full saturation with appropriate drybacks to avoid perched water and root hypoxia.
If flushing, use a measured approach rather than a last-minute deluge. Begin tapering EC in the final 7–10 days, allowing plants to metabolize residuals without sudden stress. This measured finish helps coax a clean burn, white ash, and peak flavor in the jar.
Comprehensive Cultivation Guide: Outdoor and Greenhouse Strategy
Outdoors, Amnesia Platinum performs best in Mediterranean or arid climates with long, dry autumns. In the Northern Hemisphere, plan for late September to late October harvest windows depending on latitude and phenotype, with earlier finishes in warmer regions. Plants can stretch to 2–3 meters in height if allowed a long vegetative period and will require robust staking or a tomato-cage style support system.
Greenhouses extend the viable range, protecting flowers from early fall rains and dews that can trigger botrytis. Passive airflow plus horizontal airflow fans are recommended to maintain leaf movement and prevent microclimates within the canopy. Shade cloth can be helpful during heat waves to keep late-flower temperatures under 28–29°C and preserve monoterpenes.
Organic programs using amended soils, compost teas, and beneficial microbes can produce outstanding terpene expression. Regular foliar IPM during veg with products such as neem alternatives, insecticidal soaps, and Bacillus-based bio-fungicides helps stay ahead of mites, thrips, and powdery mildew. Transition to non-residual, bloom-safe IPM inputs before flowers set to protect resin and flavor.
Water management is critical in late flower to reduce mold pressure. Drip irrigation with morning cycles allows surfaces to dry by evening, cutting down on overnight humidity around buds. Mulch helps regulate soil temperature and moisture, supporting microbial health and limiting irrigation swings.
Harvest Timing, Drying, Curing, and Storage
For an energetic, citrus-forward effect, many growers harvest when trichomes are mostly cloudy with minimal amber. For a slightly rounder, less racy profile, allow 5–10% amber before harvest. Pistil color is a secondary guide; rely on trichome heads to avoid misleading signals from environmental stress.
Drying should be slow and controlled to preserve the volatile citrus fraction. Target 15–21°C and 55–60% RH for 10–14 days with gentle airflow that moves the room, not the buds. Rapid drying above 23–24°C or in low humidity flattens the nose and can sharpen the smoke.
Curing continues the refinement. Jar at 62% RH and burp during the first week to release residual moisture and off-gassing, then extend the cure to 3–6 weeks for optimal flavor. Many citrus-led cultivars show their best bouquet between weeks 4 and 8, with a slow evolution from bright lemon to more complex pine-spice layers.
For long-term storage, maintain 58–62% RH in airtight, opaque containers away from heat and light. Under proper conditions, terpene and cannabinoid degradation is minimized, preserving quality for 6–12 months. Avoid frequent temperature cycling and oxygen exposure, which accelerate oxidation and terpene loss.
Yield Expectations, Resin Production, and Commercial Outlook
Indoors, skilled growers can expect 500–650 g/m² in optimized conditions with strong lighting and attentive training. Individual phenotypes may exceed this when CO2 and high PPFD are deployed alongside precise environmental control. Outdoors, single plants can reach 600–900 g or more with long veg, robust nutrition, and strong support structures.
Resin production is a key selling point. The platinum descriptor is earned by a high density of mature, bulbous trichomes that test well and press well. In solventless rosin production, 18–22% yields from top-tier flower are realistic, with some batches pushing higher; hydrocarbon extraction can return 15–25% depending on biomass quality and harvest maturity.
From a retail perspective, Amnesia Platinum bridges legacy appeal with modern expectations. Consumers familiar with Amnesia’s reputation for a decisive, creative headspace will find a recognizable experience, while the frosty finish and robust potency satisfy top-shelf buyers. In markets where daytime sativas are underrepresented next to dessert indicas, this cultivar can round out menus and appeal to a wider audience.
Shelf stability is helped by a proper cure and careful packaging. Because citrus-led terpenes are volatile, nitrogen-flushed pouches or airtight jars with humidity control packs preserve value and reduce returns. Clear, accurate labeling of harvest date, THC range, and dominant terpenes supports consumer trust and repeat purchases.
Final Thoughts and Ideal Use Cases
Amnesia Platinum by Bulk Seed Bank captures the essence of classic Amnesia while leveling up resin density and visual impact. It is unmistakably sativa-leaning, with citrus-pine aromatics and a nimble, upbeat head that many consumers favor for daytime use. The experience aligns with Leaf-reported Amnesia traits of uplifting, creative, and euphoric effects accompanied by high THC and low CBD.
Ideal use cases include brainstorming sessions, collaborative work, outdoor activities, and social gatherings where energy and clarity are assets. It is less suited for late-night sedation or deeply analgesic needs but excels when motivation and mood support are the goals. Those sensitive to racy sativas should start low and assess tolerance carefully.
For cultivators, the playbook is straightforward: control stretch, feed assertively without overdoing nitrogen in late flower, protect terpenes with careful environment and cure, and support long colas with netting. Do that, and Amnesia Platinum rewards with yields and a platinum-frosted finish that turns heads. In a crowded market, it stands as a reliable, modern sativa with a revered pedigree and real commercial legs.
In summary, Amnesia Platinum is a sharpened, resin-rich homage to one of Europe’s most influential sativas. It honors the lineage while addressing contemporary demands for potency, bag appeal, and extract performance. Whether you are chasing daytime spark or grow-room sparkle, this cultivar delivers with authority.
