Amnesia Top is a mostly sativa cultivar from Author Seeds that aligns squarely with the uplifting, citrus-leaning “Amnesia/Haze” family of genetics. Like its relatives, it is celebrated for a buoyant, creative high and a terpene ensemble that leans bright, zesty, and peppery. Its reputation rests on energetic daytime appeal, a high-THC/low-CBD profile, and a cultivation arc that rewards attentive growers with long, tapering colas and strong aromatic output.
As a modern interpretation of a classic lineage, Amnesia Top exists at the intersection of old-school Haze heritage and contemporary breeding goals. According to Leafly’s information on Amnesia-line strains, users commonly report uplifting, creative, and euphoric effects with typically high THC and minimal CBD. That broad profile frames Amnesia Top’s role as a go-to option for daytime clarity, focus, and mood elevation when dosed appropriately.
While Author Seeds keeps certain breeding details proprietary, the cultivar’s morphology and sensory traits strongly suggest a Haze-forward backbone. In practice, growers and consumers can expect a sprinty effect curve, a lemon-forward bouquet with pine and spice edges, and flowering times more typical of sativa-leaning plants. This article distills verified public information about the broader Amnesia/Haze family and integrates it thoughtfully with what’s known about Amnesia Top, offering a detailed, data-supported guide to its history, chemistry, effects, and cultivation.
Origins and Breeding History
Amnesia Top was bred by Author Seeds as a mostly sativa expression tuned for vigor, energetic effects, and bright citrus aromatics. While official line-by-line parentage has not been published by the breeder, the cultivar unmistakably channels hallmark traits of the Amnesia/Haze family. These include rapid cerebral onset, prolonged heady elevation, and a terpene pattern often anchored by terpinolene, limonene, and a peppery caryophyllene edge.
The “Amnesia” name traces back to renowned European selections that rose to prominence in the early 2000s. Those earlier Amnesia and Amnesia Haze phenotypes were widely noted for high THC, low CBD, and a sparkling, euphoric uplift. Leafly’s strain summaries for Amnesia and Amnesia Haze reiterate this shared profile, emphasizing energizing effects and citrus-forward flavor, which frames expectations for Amnesia Top.
Author Seeds’ contribution with Amnesia Top appears to be a stabilization of these desirable expressions into a consistent, grower-friendly package. Reports from the broader Amnesia genre often mention strong top colas, a stretchier sativa habit, and firm bud formation that resists collapse when adequately supported. Amnesia Top honors that blueprint while refining garden performance and aromatic intensity suitable for modern enthusiasts.
Genetic Lineage and Related Strains
Although Author Seeds has not publicly disclosed exact parental crosses, Amnesia Top likely descends from Haze-dominant lines similar to those seen in Amnesia and Amnesia Haze. Classic Haze pedigrees trace back to Southeast Asian, Jamaican, and South Asian landraces combined with a stabilizing touch of Afghani indica. The result is generally a mostly sativa chemovar with long internodes, extended flowering windows, and a terpene profile featuring terpinolene, limonene, ocimene, and caryophyllene.
Within this ecosystem, kin and cousins include Amnesia Haze, Super Lemon Haze, and other Haze-derived hybrids. Leafly’s coverage of the Haze terpene family highlights that these lines owe their bright, euphoric lift in part to terpinolene- and limonene-leaning profiles. Amnesia Top, in practice, tends to mirror this chemical fingerprint, though specific ratios vary by phenotype and growing conditions.
Amnesia Top also sits adjacent to numerous crossbreeds where Amnesia-line parents are paired with shorter, faster or more resin-forward partners. For example, vendors list hybrids such as Amnesia x AK-47, which tend to layer citrus and pine flavors with more pronounced body effects and heavy yields. In that continuum, Amnesia Top represents a cleaner sativa-side experience, prioritizing clarity and momentum over sedation.
Visual Characteristics and Structure
Amnesia Top generally grows tall with a classic sativa architecture: elongated branches, wider internodal spacing, and flexible stems that respond well to training. Under controlled indoor conditions, plants commonly reach 120–180 cm, depending on veg time and training intensity. Outdoors, particularly in Mediterranean or semi-tropical climates, heights of 200–300 cm are achievable with ample root space and strong sun exposure.
Bud formation tends toward spear-shaped colas with stacked calyxes and a high density of bulbous-headed trichomes. While not the bulkiest indica density, well-grown Amnesia Top can still show firm, elongated flowers that harden late in bloom. Support is important: cola weight increases in the final 2–3 weeks, and yoyo lines or trellis nets reduce stem stress and micro-tears that invite pathogens.
Coloration is vivid lime to forest green with occasional orange to rust pistils and a heavy frosting of resin by week 7–9 of flower. Under higher light intensities, leaf sugar surfaces glisten with a thick trichome mantle, signposting high cannabinoid and terpene production. Occasional foxtailing can appear at high canopy temperatures or excessive PPFD, so careful environmental control helps maintain compact floral structure.
Aroma and Bouquet
The dominant aromatic impression is bright citrus—often lemon or sweet orange—backed by pine, herbal haze, and a warming pepper-spice finish. This aligns with Leafly’s coverage of Amnesia Haze, which mentions earthy citrus flavors and energizing effects, as well as their overview of Haze-family terpenes. The bouquet carries a fresh-zesty lift on the front, then transitions to resinous, incense-like complexity.
Commonly reported secondary notes include cedar shavings, lemongrass, and faint floral tones that bloom as the bud breaks apart. Caryophyllene can contribute a cracked-pepper tickle in the nose, while terpinolene expresses as a sweet, fresh, almost apple-skin brightness. Together, these compounds create a layered nose that is assertive at jar open yet nuanced on closer inspection.
Aromatics intensify late in flower as terpenes concentrate, typically peaking in the last 10–14 days before harvest. Post-harvest, proper drying at 60–60 (60°F/60% RH or approximately 15.5–16.5°C at 60% RH) followed by a slow cure preserves the top notes. Poor curing conditions can flatten the citrus and magnify grassiness, so maintaining stable humidity is crucial to keep the lemon-pine-and-spice profile intact.
Flavor and Mouthfeel
On the palate, Amnesia Top tends to present a lemon-led entry with an herbal haze mid-palate and a pine-resin, peppered exhale. The citrus facet is often crisp and sparkling rather than syrupy, consistent with a limonene-forward composition. Mild sweetness can appear in cooler cures, while warmer or rushed drying may tilt the flavor toward herbal astringency.
Retrohale often emphasizes cedar, black pepper, and faint clove warmth, pointing to beta-caryophyllene and perhaps traces of humulene. Terpinolene contributes a fresh, almost minty brightness that keeps the flavor from feeling heavy. With vaporizers set between 175–190°C, the citrus and floral top notes remain pronounced, and the mouthfeel is lighter and cleaner than combusted smoke.
When combusted, smoke density is medium, and the peppered finish is more prominent. Sensitive palates may detect a slight bitterness at the back of the tongue if the cure is incomplete. As with most terpene-rich sativa-leaning cultivars, a patient cure over 3–6 weeks delivers the most articulate and stable flavor.
Cannabinoid Profile and Potency
Amnesia Top sits in the high-THC, low-CBD band typical of the Amnesia/Haze family. For reference, vendors commonly report Amnesia Haze testing above 20% THC with CBD below 1%, and Leafly notes Amnesia strains generally skew high THC and low CBD. In practice, Amnesia Top samples often fall in the 18–26% THC range with 0–1% CBD, yielding a THC:CBD ratio that can exceed 20:1.
Minor cannabinoids may include CBG in the 0.1–1.0% range and occasional trace CBC or THCV under 0.2–0.5%. These values are influenced by phenotype, cultivation, and post-harvest handling, so variability is expected between grows. Total active cannabinoids in well-grown, carefully cured flowers often land between 20–28% by weight when THC dominates.
Potency perception depends on terpene synergy, dosing route, and user tolerance. Inhalation onset is typically felt within 2–5 minutes, peaking at 20–40 minutes and sustaining for 2–3 hours at moderate doses. Edible formulations using Amnesia Top may need 30–90 minutes for onset, with a 2–4 hour peak and total duration of 4–8 hours, heavily influenced by individual metabolism.
Dominant Terpenes and Chemical Ecology
Amnesia/Haze chemotypes are frequently terpinolene- or limonene-dominant with a supporting cast of beta-caryophyllene, myrcene, and ocimene. Leafly’s analysis of Haze-family terpenes connects terpinolene-rich profiles with the sparkling, euphoric uplift that many users report. In Amnesia Top, the common pattern is limonene (citrus lift), terpinolene (fresh, sweet-herbal top), and caryophyllene (pepper-clove warmth), though specific ratios will vary by phenotype and grow method.
Quantitatively, total terpene content in well-grown Amnesia-type flowers often ranges from 1.5–3.5% of dry weight, with standout batches exceeding 4% under optimized conditions. Within that total, limonene frequently falls between 0.3–0.8%, terpinolene between 0.2–1.5%, and beta-caryophyllene between 0.1–0.5%. Myrcene and ocimene commonly appear in the 0.1–0.4% band each, contributing to herbal-sweet and green, decongestant-like facets.
From a functional perspective, terpinolene has been associated in preclinical work with stimulating yet clear-headed effects, while limonene has shown anxiolytic potential in animal models and small human studies. Beta-caryophyllene interacts with CB2 receptors, which may influence inflammation pathways without a classic “high.” Interactions among these terpenes and high THC may help explain the reported uplift, creativity, and focus associated with Amnesia-line strains.
Experiential Effects and Use Cases
User reports across Amnesia and Amnesia Haze suggest a consistent triad of uplifting, creative, and euphoric effects, with Leafly explicitly listing these experiences for Amnesia. Amnesia Top tracks closely with those results, delivering a fast, head-forward rise and a clear sense of forward momentum. Many people describe enhanced ideation, a desire to organize or execute tasks, and music or art appreciation at moderate doses.
Dutch Passion’s commentary on Amnesia-type strains notes a reputation for productivity and an “unwavering focus” for less cerebrally demanding tasks. That squares with how Amnesia Top often functions for daytime use—encouraging activity without heavy body weight. At higher doses, the energy can tip into raciness or mental loops for sensitive users, so self-titration is advised before engaging in complex responsibilities.
Common side effects mirror other high-THC sativas: dry mouth, dry eyes, increased heart rate, and occasionally transient anxiety or unease. These are more likely with large, rapid doses, especially in low-tolerance users or those prone to anxiety. Starting low and pacing the session typically preserves the bright, task-friendly arc while minimizing overstimulation.
Potential Medical Applications and Evidence
Amnesia Top’s high-THC/low-CBD character and limonene/terpinolene-forward terpene pattern suggest potential utility for mood elevation, fatigue, and select neuropathic pain presentations. Leafly’s overview of Amnesia indicates uplifting, creative, and euphoric effects, which may translate into short-term relief for depressive symptoms in some individuals. However, evidence for cannabis as a primary treatment for depression remains mixed, and professional medical guidance is recommended.
For pain, the broader literature shows moderate evidence for cannabinoids assisting with chronic pain, particularly neuropathic pain, though responses vary considerably. Beta-caryophyllene’s CB2 activity is of interest for inflammatory pathways, and limonene’s anxiolytic signals in preclinical work may support stress mitigation. A high-THC sativa like Amnesia Top may help with daytime pain or fatigue when sedation is not desired, but anxiety-sensitive individuals should proceed carefully.
Users also report appetite stimulation and relief from nausea with high-THC cultivars, and a clear-headed profile can be desirable for chemotherapy-related symptom management in selected cases. Conversely, the brisk headspace can be counterproductive for panic-prone patients or those with bipolar disorder unless carefully supervised. This information is educational and not a substitute for professional medical advice—patients should consult clinicians familiar with cannabinoid medicine for personalized recommendations.
Comprehensive Cultivation Guide
Amnesia Top responds best to patient, attentive cultivation that respects its mostly sativa metabolism. Indoors, plan for a moderate-to-long bloom window and a pronounced stretch, with many plants doubling in height after the flip. The cultivar excels in both coco and living soil and performs strongly in SCROG setups that distribute light evenly across lanky branches.
Germination and early seedling care: Use a gentle start with 0.4–0.6 mS/cm EC and pH 5.8–6.0 in hydro/coco or 6.2–6.5 in soil. Maintain 24–26°C air temperature with 70–75% RH for vigorous emergence and keep PPFD around 150–250 µmol/m²/s. Avoid overwatering—sativa-dominant seedlings prefer rapid wet-dry cycles with ample oxygen to the root zone.
Vegetative growth: Target 22–28°C with 60–70% RH and a VPD of 0.8–1.1 kPa. Feed a 3-1-2 NPK ratio at EC 1.1–1.4 in coco/hydro, and use a biologically active soil for living-organic programs. Light levels of 400–600 µmol/m²/s with an 18/6 schedule encourage compact nodes without excessive stretch.
Training: Top at node 4–5, then low-stress train to flatten the canopy; sativas respond exceptionally well to SCROG with 5–8 cm mesh spacing. Defoliate lightly to open airflow through the mid-canopy, removing large fans that cast heavy shade. Aim for 6–12 main tops per plant in a 1 m² SCROG to maximize light interception without overcrowding.
Transition to flower: Expect a 1.5–2.0x stretch in the first two weeks after switching to 12/12. Increase PPFD to 700–900 µmol/m²/s initially, then 900–1100 µmol/m²/s by mid-flower if CO2 is supplemented to 1000–1200 ppm. Without added CO2, cap PPFD near 900–1000 µmol/m²/s to avoid light stress and foxtailing.
Flowering environment: Keep day temps 24–27°C, night 18–21°C, holding RH at 50–55% early bloom and 45–50% late bloom for mold control. Maintain VPD between 1.1–1.4 kPa; sativa flowers are sensitive to high humidity, especially on dense upper colas. Gentle oscillating airflow at multiple canopy levels reduces microclimates and deters botrytis.
Nutrition in bloom: Shift to a 1-3-2 NPK ratio with EC 1.5–1.9 mS/cm in coco/hydro, tapering nitrogen from week 4 onward. Supplement sulfur and magnesium judiciously—terpene synthase activity benefits from adequate S and Mg but avoid overshooting, which can cause leaf burn. Many growers report that Haze-leaning plants prefer a steady, moderate feed over heavy spikes; watch leaf color and tip burn to dial the EC.
Irrigation strategy: In coco, small, frequent fertigations keep root-zone EC stable and oxygen high—target 10–20% runoff to prevent salt buildup. In soil, deep but infrequent waterings encourage robust root development; let the top inch dry between events. Root-zone temperatures around 20–22°C support optimal uptake and microbial activity.
Flowering time and yields: Anticipate 9–11 weeks of flowering (63–77 days) depending on phenotype and environment. Indoors, yields of 450–650 g/m² are achievable under optimized LEDs with strong canopy management; outdoors, 600–900 g/plant is realistic in full sun with large containers or in-ground culture. The Amnesia genre has a reputation for firm, large buds when dialed in, a point echoed in Dutch Passion’s citrus-flavor strain writeups that spotlight Amnesia types for strength and grower friendliness.
Pest and disease management: The long bloom window requires vigilance for powdery mildew, spider mites, and botrytis. Preventively, maintain good airflow, manage humidity, and consider biological controls such as predatory mites (Phytoseiulus persimilis for spider mites; Amblyseius swirskii for thrips/whitefly). Avoid foliar sprays in late bloom; if needed earlier, use potassium bicarbonate or biologicals and allow full drying before lights on.
Advanced tips: Consider UV-A/UV-B supplementation in late flower at modest intensities to potentially enhance resin biosynthesis without stressing the canopy. For flavor maximization, stabilize day-night temperature differentials at 3–5°C and avoid late-stage nitrogen. Monitor runoff EC and pH closely from week 6 onward; Haze-leaning flowers can be sensitive to salt accumulation, which dulls terpenes and slows ripening.
Harvest, Drying, and Curing
Identifying the harvest window for Amnesia Top benefits from trichome inspection rather than calendar days alone. Target milky/cloudy trichomes with 5–10% amber for a balanced, bright psychoactive profile. Pulling earlier at mostly cloudy minimizes sedation and keeps the effect zippier; pushing to 15% amber adds a touch more body weight at the expense of some clarity.
Pre-harvest, consider a 7–10 day nutrient taper or clear-water finish in coco/hydro to improve burn quality and reduce residual salts. In living soil, simply stop heavy feeds and let the microbial system complete the cycle naturally. Avoid extreme flushes that can shock roots and stall ripening in sativa-leaning plants.
Dry in a stable 60°F/60% RH environment (about 15.5–16.5°C) with gentle airflow, targeting a 10–14 day dry until small stems snap. Keep darkness and minimal handling to protect fragile monoterpenes like limonene and terpinolene. Once jarred, cure at 62% RH, burping daily for the first week and then weekly for 3–6 weeks to round the citrus and haze notes.
Properly cured Amnesia Top showcases its lemon-forward top end, resinous pine mid-body, and peppery tail without harshness. Over-drying below 55% RH can flatten aromatics and accentuate bite, while overdamp storage invites mold. Hygrometers in jars provide a simple, data-driven safeguard for long-term quality.
Storage, Shelf Life, and Quality Preservation
Store cured flowers in airtight, opaque containers at 15–20°C and 55–62% RH to preserve volatile terpenes. Light, heat, and oxygen accelerate THC oxidation to CBN and degrade monoterpenes like limonene, causing a noticeable dulling of aroma. In controlled storage, terpene loss can be limited to gradual declines over months rather than weeks.
For long-term preservation beyond 3–6 months, consider refrigeration at stable temperatures, ensuring jars are fully sealed to prevent moisture swings and odor cross-contamination. Freezing can arrest degradation but risks trichome brittleness and terpene condensation; it is best reserved for material destined for extraction. Always allow containers to reach room temperature before opening to avoid condensation on the flowers.
When stored correctly, potency remains robust for several months, with the most dramatic sensory shifts occurring in the first 60–90 days if conditions are suboptimal. A data-driven approach—tracking RH, temperature, and periodic sensory checks—ensures Amnesia Top retains its signature citrus-bright profile. Avoid repeated open-close cycles that vent terpenes; plan usage to minimize unnecessary exposure.
