Written by Ad OpsOrigins and Breeding History
Amnesia Autoflower is a modern, auto-flowering expression of the storied Amnesia lineage, crafted to deliver Haze-driven vigor in a compact, time-efficient package. SeedStockers, a Barcelona-based breeder known for stabilizing high-performing autos, is credited as the breeder for this specific cut. They combined a photoperiod Amnesia parent with robust Cannabis ruderalis genetics, creating a line that flowers by age rather than light schedule. The result is a cultivar that compresses the essence of classic Amnesia into a 10–12 week seed-to-harvest timeline for most growers.
The Amnesia family traces its roots to the late 1990s and early 2000s European scene, where Haze, Skunk, and Northern Lights lines converged. The best-known branch, Amnesia Haze, surged in popularity through Dutch coffee shops and international competitions, highlighting terpinolene-forward profiles and cerebral intensity. Autoflowering technology exploded in the 2010s as breeders improved yield, cannabinoid content, and stability, pulling autos out of novelty status. Today, Amnesia Autoflower represents that maturation, exhibiting potency and quality that rivals many photoperiod strains.
Commercial listings reflect this evolution, with multiple marketplaces categorizing Amnesia Autoflower as very high in THC. For example, SeedSupreme lists Amnesia Autoflower in the “Very High (over 20%)” potency bracket, a threshold once rare in autos. Closely related offerings like Blue Amnesia Autoflower are frequently rated in the 15–20% THC range, demonstrating how Amnesia-based autos scale across potency tiers. Reports from Amsterdam Genetics on Blue Amnesia, a cousin phenotype, describe a fast-hitting and prolonged high that resolves into a relaxing body buzz—an arc consistent with many Amnesia autos.
SeedStockers’ approach emphasizes accessibility and repeatable performance with minimum fuss. Autoflowers enable outdoor growers to stack multiple harvests per season even at higher latitudes, and Amnesia Autoflower was selected to match that practicality with a recognizable Haze-style experience. As a ruderalis/indica/sativa hybrid, it fuses hardiness, manageable structure, and racy uplift. Historically, that blend was difficult to achieve in a single automatic plant; now, it is mainstream.
The strain’s rise reflects broader consumer trends favoring shorter grow cycles without sacrificing oil content or terpene complexity. By bringing Amnesia’s electrifying headspace into an auto format, breeders lowered barriers for novice cultivators. Meanwhile, experienced growers can push the line toward significant yields and rich secondary metabolite expression. In short, Amnesia Autoflower is both a historical homage and a forward-looking tool for efficient cultivation.
Anecdotally, the strain earned a reputation for predictability across environments, a crucial milestone for autos. Early-day autoflowers suffered from variable height, potency, and quality, but modern lines narrowed those gaps through rigorous selection. As more third-party retailers and seedbanks adopt standardized potency labeling, the profile of Amnesia Autoflower continues to solidify. That validation helps growers plan their space, schedules, and post-harvest goals with greater confidence.
Genetic Lineage and Botany
Amnesia Autoflower carries a mixed heritage of ruderalis, indica, and sativa, purposefully blended to express Amnesia’s sativa-forward head while retaining auto-flowering behavior. In practical terms, the ruderalis portion confers photoperiod independence, cold tolerance, and rapid lifecycle. The indica influence contributes to compact internodes, faster resin maturation, and a grounding body finish. The sativa ancestry drives canopy vigor, extended apical growth, and a terpene bouquet often led by terpinolene and limonene.
Though exact parent lines are typically proprietary, conventional Amnesia genealogy references Haze, Skunk, and Afghan lines in its ancestry. These building blocks explain the cultivar’s energetic, citrus-pine perfume and dense, resin-frosted calyxes. In the autoflower conversion, breeders backcross Amnesia-leaning phenotypes with a stable ruderalis donor, then select for potency, uniformity, and terpene expression. The result is a hybrid that grows like a medium-height sativa but behaves like a schedule-free ruderalis.
Botanically, plants tend to develop a strong central cola with several satellite branches, especially under minimal training. Internodal spacing is moderate, allowing light penetration while still stacking dense flower clusters. Calyx-to-leaf ratio is favorable compared with older autos, easing trimming and accelerating dry-down. Trichome coverage is pronounced even on small sugar leaves, reflecting selection pressure for resin output.
Amnesia Autoflower typically completes its entire lifecycle in 70–85 days from sprout under optimal conditions. Some phenotypes finish earlier at 63–70 days, while heavier-yielding or sativa-leaning expressions may require up to 90 days to prime trichomes. Height usually falls between 60–110 cm indoors, influenced by pot size, light intensity, and nutrition. Outdoors, 70–120 cm is common, with larger containers pushing plants to the upper range.
The genetic trifecta also shapes stress tolerance and feeding behavior. Compared to many photoperiod sativas, this auto accepts moderate EC without clawing when environmental parameters are tight. However, it remains sensitive to overwatering and heavy early topping due to its fixed vegetative window. Smart, low-stress training maximizes lateral sites while keeping the timeline intact.
From a breeding perspective, Amnesia Autoflower demonstrates the success of modern auto stabilization protocols. It captures a largely sativa effect in an efficient, resilient framework. Because the ruderalis component is expressed in flowering behavior rather than overt morphology, many plants still look and smell like classic Amnesia by mid-bloom. That balance is why the line remains in high rotation among home and micro-growers.
Appearance and Morphology
At maturity, Amnesia Autoflower plants present a harmonious silhouette: a firm central spear flanked by symmetrical side branches. Colas are elongated and tapering, with bright lime to medium-green bracts that stack tightly in good environmental conditions. By late bloom, flowers are heavily sugared, with glistening trichome heads visible even under ambient light. Copper-orange pistils weave throughout, turning darker as ripening advances.
The calyxes swell appreciably during weeks six to nine, improving bag appeal and weight. In higher light environments, a subtle foxtailing can occur, especially in terpinolene-forward phenotypes. This is typically aesthetic rather than a symptom of stress if temperatures and VPD remain within range. Leaves lean narrow to medium-width, reflecting the sativa bias with enough indica to stay compact.
Twig thickness supports the dense inflorescences without extensive staking, but larger plants benefit from soft ties or a trellis net. The calyx-to-leaf ratio is notably favorable, making post-harvest trimming quicker than many indica-dom autos. Resin glands are abundant on bracts and sugar leaves, and stalked trichomes are prevalent under magnification. A light rub on mid-flower sugar leaves leaves fingers sticky and aromatic.
Under LED lighting at 800–1000 µmol/m²/s, plants remain short-to-medium with tight node spacing. Halogen or lower PPFD levels produce slightly taller internodes and airier colas but still respectable density. In organic living soil, coloration can deepen to forest green with lighter tips as calcium and magnesium demands are met. Occasional purple hues can emerge in cool nights, but it’s less common than in anthocyanin-rich crosses.
Outdoors, the plant’s morphology adapts well to variable conditions. The central cola can grow notably tall in 20–30 liter containers with full sun, often delimiting the plant’s final height. Side branching in outdoor grows develops into multiple medium colas, especially when early low-stress ties encourage horizontal growth. The overall structure balances airflow with mass, reducing mold pressure when humidity is managed.
Root development is vigorous when transplants are minimized or avoided. Direct sowing to final containers supports a thick, fibrous rootmass that powers mid-bloom bulking. Fabric pots or air-pots enhance lateral root pruning and oxygenation, enhancing nutrient uptake efficiency. With the right container and irrigation rhythm, the plant exhibits strong turgor and sustained growth through its compact lifecycle.
Aroma and Bouquet
Amnesia Autoflower’s bouquet is unmistakably in the Haze family, with high-notes of citrus zest, pine resin, and fresh herbs. Early in flower, the aroma is bright and effervescent, suggesting lemon peel and green apple skin. As resin glands mature, deeper tones of incense, cedar, and white pepper emerge. A sweet, almost floral top note rounds the composition, especially after a proper cure.
A jar test after two weeks of curing reveals a layered experience. Cracking the lid releases terpinolene-driven aromatics that many describe as “sparkling” or “fizzy.” Secondary currents of limonene and ocimene lend juicy, sweet-fruit accents. In the background, beta-caryophyllene and humulene supply a peppery, herbal hum that grounds the brightness.
Compared to photoperiod Amnesia phenotypes, the autoflower maintains the same terpene direction with slightly more resinous, piney edges in some cuts. This is likely due to selection for thick trichome heads and robust glandular development in a shorter timeframe. Under cool, dry finishing conditions, the spice-and-cedar note becomes more pronounced. The bouquet remains clean and invigorating, with no heavy musk dominating the profile.
Environmental factors play a significant role in aromatic intensity. Plants finished at 35–40% RH with stable temperatures develop a crisper top note and better terpene preservation. Overly warm late bloom conditions can dull the citrus and accentuate herbaceousness. A slow, 10–14 day dry at 18–21°C and ~55% RH retains volatility and complexity.
It is worth noting that related variants like Blue Amnesia Autoflower are often reported to add a berry-sweet layer to the classic Amnesia scent. Retail references commonly list Blue Amnesia at 15–20% THC and associate it with a fast-hitting yet velvety bouquet. While SeedStockers’ Amnesia Autoflower is not the blueberry-crossed variant, the comparison underscores how the Amnesia base conveys a consistent citrus-incense axis across cousins. That axis is the aromatic signature many growers seek.
On the grind, the aroma returns to fresh citrus rind and juniper, with the spice more apparent. This makes Amnesia Autoflower particularly attractive for daytime consumption scenarios where bright, uplifting scents are desirable. The smell projects well without overwhelming a room, and it lingers pleasantly on fingers and tools. In vaporizers, the bouquet translates cleanly with terpene clarity at 170–190°C.
Flavor and Mouthfeel
The flavor of Amnesia Autoflower mirrors its nose with an agile mix of lemon-lime, pine, and sweet herbal tea. On inhale, citrus oils pop first, accompanied by an effervescent tang that feels sparkling on the palate. The mid-palate brings in cedar and faint anise, aligning with Haze lineage expectations. Exhale trends spicy and peppered with a cooling, resinous finish.
In joints, the smoke is smooth when properly cured, with a light, zesty sweetness that balances the spice. Combustion at lower temperatures preserves the citrus bloom and keeps cedar from dominating. Higher-heat pulls, such as through bongs, drive pepper and herb notes to the forefront. A clean white ash is common when the plant is flushed or fertigated correctly and dried slowly.
Vaporization highlights the top-end terpenes with remarkable clarity. At 170–180°C, terpinolene and limonene expression leads to a bright, citrus-pine experience. Raising to 185–195°C brings caryophyllene’s pepper and humulene’s herbal qualities into focus. The mouthfeel shifts from sparkling and crisp to warm and resinous as temperature increases.
Under organic feeding regimes with living soil, many report a slightly sweeter, more rounded flavor. Salt-based programs can produce an ultra-clean, crisp profile with pronounced lemon and pine. Both can be excellent, but prolonged curing (4–8 weeks) typically unlocks deeper cedar and sweet-tea notes. All else equal, a slower dry and cure broaden the flavor band considerably.
Blue Amnesia cousins often show berry-citrus candy layers in the flavor, a point of comparison for tasters. Those berry notes are not typical of SeedStockers’ Amnesia Autoflower itself, which remains squarely citrus-incense. Retail data suggests both occupy the same potency neighborhood, though specific lots vary. Overall, Amnesia Autoflower is best described as bright, piney, and polished with a peppered exhale.
The finish lingers pleasantly and cleanses the palate rather than coating it heavily. That makes it friendly for daytime sessions, where flavor fatigue can be a factor. Pairings with citrus fruits, green tea, or mint emphasize its high notes. More indulgent pairings, like dark chocolate, pull forward the cedar and spice for a richer experience.
Cannabinoid Composition and Potency
Amnesia Autoflower is consistently marketed as a high-potency auto, with many listings placing it above the 20% THC threshold. SeedSupreme, for example, categorizes Amnesia Autoflower as “Very High (over 20%),” aligning with modern autos that rival photoperiod potency. By contrast, Blue Amnesia Autoflower variants are commonly rated in the 15–20% THC range, showcasing how related lines scale across intensity. This suggests a practical potency band for Amnesia-based autos spanning roughly 15–24% THC depending on breeder, phenotype, and cultivation.
CBD content is typically low in Amnesia-type autos, commonly falling below 1%. Trace cannabinoids like CBG may reach 0.5–1.5% in some phenotypes, especially under optimized UV and late-flower light spectra. While comprehensive third-party panel data varies by batch, the general pattern is THC-dominant with minor acid forms present. Growers seeking balanced THC:CBD ratios should note that Amnesia Autoflower is not bred for CBD expression.
The pharmacodynamic profile of a high-THC, low-CBD cultivar explains the rapid onset and pronounced euphoria. Inhalation commonly produces first effects within 2–5 minutes, peaking at 20–40 minutes, with a total duration of 2–3 hours for experienced users. Oral routes extend onset to 30–90 minutes and duration to 4–6 hours or more. Individual sensitivity, set and setting, and tolerance strongly modulate perceived effect intensity.
From a cultivation standpoint, resin density and trichome head size correlate with potency outcomes. Optimizing PPFD to 800–1000 µmol/m²/s in bloom and maintaining a balanced DLI under 18–20 hours of light tends to push THC expression upward. Nutritionally, adequate micronutrients and sulfur levels during weeks 5–9 support terpene synthase activity, indirectly affecting perceived potency. Finally, harvest timing—particularly trichome maturity—shifts subjective intensity and character.
Due to its potency bracket, Amnesia Autoflower is generally recommended for intermediate to experienced consumers. Newer users should start with small inhalations and longer intervals to properly titrate. Sensitive individuals may experience transitory anxiety at high doses typical of terpinolene-forward sativas. Hydration, a calm environment, and mindful pacing help optimize the experience.
Overall, the cannabinoid profile is best summarized as THC-dominant, CBD-light, with minor cannabinoid contributions shaping nuance. This archetype underpins the cultivar’s energetic, euphoric signature and amplifies its top-end terpenes. When combined with proper curing, the potency feels strong yet refined. For many, it lands squarely in the “daytime but powerful” category.
Terpene Spectrum and Chemistry
Amnesia Autoflower’s terpene spectrum typically centers on terpinolene, supported by limonene, beta-caryophyllene, and ocimene. In many Amnesia-leaning autos, terpinolene can account for 0.5–1.5% of dried flower mass, though actual values vary by phenotype and cultivation. Limonene often ranges 0.2–0.5%, amplifying citrus aromatics and potentially modulating mood. Beta-caryophyllene, frequently 0.2–0.6%, contributes pepper-spice and engages CB2 receptors.
Humulene and myrcene commonly appear as secondary components, each in the 0.1–0.4% band. Humulene’s woody, herbal notes stabilize the bouquet, while myrcene’s earthy sweetness enriches mid-palate depth. Ocimene adds a floral-sweet lift that keeps the profile lively and fresh. Minor terpenes like alpha-pinene and linalool show in trace levels that nonetheless influence perceived clarity and calm.
Terpene expression is sensitive to environmental controls. Maintaining late-bloom temperatures below 26°C while avoiding RH spikes above 50% helps preserve volatile monoterpenes such as terpinolene and limonene. A slow dry at ~55% RH for 10–14 days curbs terpene loss compared to rapid drying. Light exposure during drying and curing should be minimized to prevent oxidation.
The chemistry of terpinolene-forward cannabis correlates with stimulating, creative effects reported widely for Amnesia lines. Limonene may synergize with THC to uplift mood in many consumers, while caryophyllene can add a relaxing edge by binding to CB2. This constellation often yields a bright, clear onset with a clean comedown if dosage is managed. The balance of these compounds likely underpins the cultivar’s reputation for a long, tapering high.
Fertilization nuances affect terpene outcomes. Sulfur is a critical cofactor for terpene synthesis; ensuring adequate sulfur (e.g., via gypsum or Epsom salt in balanced amounts) can enhance aroma. Micronutrients like manganese and zinc also support enzyme systems related to terpene pathways. In living soils, microbial diversity can further boost complexity through improved nutrient cycling.
Relative to many indica-dominant autos, Amnesia Autoflower’s terpene stack leans brighter and woodier. This aligns it with daytime usage and makes it a popular base for extracts emphasizing citrus and pine. Mechanical separation methods like dry sift often produce notably fragrant kief from this line. Properly managed rosin presses retain the zingy top notes that define the profile.
Experiential Effects and Use Cases
User reports consistently describe Amnesia Autoflower as fast-hitting and long-lasting, with an uplifting cerebral onset that gradually transitions into a balanced body relaxation. The early phase often features heightened focus, creative ideation, and a buoyant mood. As the session progresses, a warm, soothing body tone unfurls without heavy couchlock in moderate doses. Many consider it a “get-things-done” strain with a gentle landing.
This arc is echoed in related variants such as Blue Amnesia Autoflower. Amsterdam Genetics characterizes Blue Amnesia’s high as “fast-hitting and very prolonged,” easing into an indica body buzz. That pattern closely mirrors mainstream Amnesia Autoflower feedback, though the berry-crossed variant adds a sweeter flavor dimension. The similarity underscores the consistency of effect architecture across the Amnesia auto family.
Onset times are quick with inhalation—often noticeable within 2–5 minutes. Peak intensity arrives around the 20–40 minute mark and gradually declines over the next hour or two. Oral ingestion extends both onset and duration, and the body component becomes more pronounced. As with most high-THC sativas, high doses may provoke transient edginess in sensitive users.
Use cases commonly include creative work, light outdoor activities, and social settings where conversation flows. Many report improved task engagement, especially for novel or open-ended projects. The cultivar’s bright sensory profile pairs well with music, design, and brainstorming sessions. At the same time, its resolving body ease makes it suitable for late afternoon decompression.
When the goal is productivity, measured dosing is key. One or two small inhalations can deliver lift without overwhelming intensity. Hydration, a light snack, and a comfortable environment further smooth the experience. Users new to high-THC autos should titrate slowly to find their sweet spot.
The comedown tends to be clear and unhurried, minimizing residual fog. With proper pacing, many find no need for a “recovery window,” even on busy days. However, stacking multiple sessions can accumulate sedation, particularly if the last dose lands within an hour of bedtime. Adjust timing and dosage to match daily rhythms and responsibilities.
Potential Medical Uses and Safety Considerations
While clinical data on Amnesia Autoflower specifically are limited, its cannabinoid-terpene profile suggests potential utility for several symptom domains. The uplift and energy often appeal to those managing low mood or anhedonia, where a bright, motivational effect is desired. The caryophyllene content, combined with THC, may contribute to perceived analgesic and anti-inflammatory effects. Limonene and terpinolene are frequently associated with mood elevation and alertness in user reports.
Common anecdotal applications include stress relief, fatigue, and situational anxiety where energizing focus is beneficial at low doses. Some users report relief from tension headaches and low-level neuropathic discomfort, potentially due to THC’s central effects and caryophyllene’s CB2 engagement. The strain’s gradual body relaxation can also support muscle ease after exercise or physical work. For appetite, THC-dominant autos sometimes induce mild hunger, which can be advantageous in select cases.
Safety considerations largely mirror other high-THC, low-CBD cultivars. At higher doses, susceptible individuals may experience anxiety, racing thoughts, or a transient increase in heart rate. Those prone to panic attacks should start with minimal inhalations and consider strains with higher CBD if undesirable intensity occurs. Hydration and a calm environment are practical tools for mitigating acute overstimulation.
Cognitive impairment—short-term memory lapses and slowed motor coordination—can occur during peak effects. As with all cannabis, do not drive or operate machinery under the influence. Interactions with medications, particularly sedatives or drugs metabolized by CYP450 enzymes, are possible. Patients should consult a qualified healthcare professional before integrating cannabis into a therapeutic plan.
For novice users, microdosing can deliver functional benefits with reduced side effects. Inhaled microdoses might involve one short puff, waiting 10–15 minutes before considering another. Edible microdoses could begin at 1–2.5 mg THC, observing effects for several hours before redosing. Journaling tolerance, symptom changes, and timing helps refine a personalized protocol.
As always, these potential benefits are not medical advice and may not generalize to every individual. Variability in body chemistry, set and setting, and product quality can substantially impact outcomes. Selecting a tested batch with clear cannabinoid and terpene data improves predictability. When in doubt, start low, go slow, and seek professional guidance.
Comprehensive Cultivation Guide
Lifecycle and scheduling
Amnesia Autoflower typically finishes in 70–85 days from sprout under optimal indoor conditions. Early-finishing phenotypes can be ready around day 63–70, while larger expressions may push to 85–90 days. Because autos flower by age, minimizing early stress is paramount to preserve yield potential. Plan your training and feeding to fit a tight vegetative window of roughly 3–4 weeks before full bloom onset.
Choose an 18/6 or 20/4 light schedule from seed to harvest. Many growers report slightly faster development and denser buds at 20/4 due to higher daily light integral (DLI). Aim for PPFD of 400–600 µmol/m²/s in early veg, 600–800 µmol/m²/s in late veg, and 800–1000 µmol/m²/s in bloom. A DLI of 35–45 mol/m²/day balances growth and terpene retention for most phenotypes.
Environment and VPD
Keep daytime temperatures at 24–28°C and nighttime at 18–22°C. Relative humidity should start around 65–70% for seedlings, step down to 55–60% in veg, then 45–50% in early bloom. Finish at 35–40% RH in late bloom to protect trichomes and reduce botrytis risk. Target VPD of 0.8–1.0 kPa in veg and 1.2–1.5 kPa in bloom for steady transpiration.
Ensure vigorous air exchange with 30–60 air changes per hour in small tents and active intake or strong passive intakes. A gentle but constant canopy breeze strengthens stems and discourages pests. Carbon filters paired with quiet inline fans manage odor while maintaining negative pressure. Use oscillating fans at multiple heights to prevent microclimates around dense colas.
Mediums, containers, and watering
Autos benefit from direct sowing into final containers to avoid transplant shock. Use 11–19 liter (3–5 gallon) fabric pots for indoor runs, or 20–30 liters outdoors in full sun. In soil, maintain pH 6.2–6.8; in coco or hydro, keep pH 5.8–6.2. Water to 10–20% runoff when the top 2–3 cm of medium is dry, adjusting frequency to pot size and environment.
Living soil blends with ample aeration (30–40% perlite, pumice, or rice hulls) support steady growth without daily fertigation. Coco-coir with 10–30% perlite excels for aggressive growth via frequent light feeds. Always charge coco with calcium and magnesium before use. Avoid chronic overwatering during the first two weeks to prevent slow starts.
Nutrition and EC management
Begin seedlings on 0.3–0.6 mS/cm (150–300 ppm 500-scale) including base water. Step to 1.0–1.2 mS/cm in early veg and 1.2–1.4 mS/cm in late veg. Bloom typically responds well to 1.6–2.0 mS/cm depending on cultivar appetite and environment. Monitor runoff EC and adjust input by ±0.2 mS/cm to keep plants balanced.
Autos dislike heavy nitrogen late into bloom; taper N after week 4–5. Emphasize phosphorus and potassium from mid-bloom onward to support bud expansion and resin production. Maintain adequate sulfur and magnesium for terpene synthesis and chlorophyll stability. In organic systems, top-dress with bloom amendments by day 21–28 to ensure availability during peak demand.
Training and canopy management
Low-stress training (LST) is preferred over topping due to the fixed vegetative window. Begin LST around day 14–21 when the fourth node appears, gently bending the main stem to open the canopy. Space out lateral branches with plant ties to create an even, multi-top structure. Avoid heavy defoliation; remove only leaves that block multiple bud sites or restrict airflow.
If topping is used, limit to one early top at the 3rd–4th node by day 14–18, accepting a minor slowdown. A SCROG net can be installed by day 21–28 to guide shoots horizontally without topping. Strategic lollipopping around day 35–42 channels energy to top sites. Stop major training by mid-bloom to prevent stress during the bulking phase.
Irrigation strategy and root health
Autos excel with frequent, lighter irrigations that maintain high oxygen in the root zone. In coco, aim for 1–2 small fertigations daily in veg and 2–3 in bloom depending on pot size and VPD. In soil, water thoroughly, then allow the medium to approach lightness before rewatering. Root-zone temperatures of 20–22°C promote rapid uptake; cooler roots slow metabolism.
Inoculate with mycorrhizae at sowing and first watering to improve nutrient access. Beneficial bacteria and Trichoderma can enhance disease resistance. Maintain clean lines and reservoirs in hydroponic or coco systems to prevent biofilm build-up. Periodically flush with a mild enzyme solution to keep media free of salt lockout.
Pest and disease management
Preventive IPM is more effective than reaction in a 10–12 week cycle. Sticky cards, weekly leaf inspections, and clean intakes catch issues early. Neem alternatives like azadirachtin-free botanical oils, Beauveria bassiana, or spinosad (where legal) can be used in veg. Stop foliar sprays by early bloom to protect trichomes and avoid residue.
Good airflow and RH discipline are your best defenses against botrytis in dense colas. Space plants adequately and avoid wet leaves at lights-off. Sanitize tools and surfaces between runs and quarantine new clones or plants if applicable. Keep grow spaces free of plant debris to disrupt pest lifecycles.
Indoor yield expectations
Indoors under efficient LEDs, trained plants in 11–19 L pots commonly yield 350–500 g/m². Skilled growers pushing PPFD, dialing VPD, and optimizing nutrition can reach 500–600 g/m². Per-plant yields of 60–150 g are typical depending on container size and training. In terms of efficiency, 0.8–1.6 g/watt is achievable in optimized environments.
Outdoor and greenhouse performance
Outdoors, Amnesia Autoflower thrives in full sun with at least 6–8 hours of direct light. Expect 50–200 g per plant depending on container size, climate, and season timing. Autos allow two or even three runs per warm season at mid-latitudes: spring, midsummer, and early fall. Greenhouses extend the season and buffer against rain, reducing mold pressure as flowers densify.
Harvest timing and maturity cues
Monitor trichomes from week 8 onward with a 60–100× loupe. For a bright, energetic effect, harvest around 5–10% amber trichomes with mostly cloudy heads. For a fuller body component, harvest at 10–20% amber. Pistil color alone is unreliable; prioritize trichome maturity and calyx swell.
Pre-harvest handling and flushing
In salt-based systems, a 7–14 day light flush with balanced pH water or a low-EC solution can improve burn and flavor. In living soil, maintain normal watering while avoiding late heavy nitrogen inputs. Reduce RH to ~40% and increase airflow the final week to firm up flowers. Keep night temps slightly cooler than day to retain terpenes without inducing stress.
Drying and curing
Dry whole plants or large branches in 18–21°C and 50–60% RH for 10–14 days. The slow dry preserves monoterpenes and stabilizes chlorophyll breakdown. When small stems snap and larger stems bend, transfer to jars at 58–62% RH using humidity packs if necessary. Burp daily for the first week, then weekly, for a 3–8 week cure that significantly enhances aroma and smoothness.
Post-harvest processing
For hash and rosin, harvest at peak terpene expression with mostly cloudy trichomes. Cold-room trimming and prompt freezing of fresh material improve live resin and live rosin quality. Dry sift benefits from low humidity and gentle agitation to maintain gland integrity. Expect bright, citrus-forward extracts with a peppered finish that mirrors the flower.
Common mistakes to avoid
Overfeeding nitrogen late bloom, which softens flavor and delays ripening, is a frequent pitfall. Heavy topping or high-stress training past week three can stunt autos and reduce yield. Overwatering seedlings slows the entire cycle by several days to a week, hurting final mass. Inadequate airflow in late bloom invites botrytis in thick colas—keep RH in check and prune for airflow.
Performance benchmarks and potency context
Retailers routinely slot Amnesia Autoflower into the “Very High” THC category, with some listings citing over 20% THC. Related Blue Amnesia Autoflower entries often sit at 15–20% THC, indicating the family’s credible potency band. Under optimized conditions, expect strong, heady effects with a pronounced terpene signature. That potency, coupled with a 10–12 week timeline, defines the cultivar’s appeal for both new and seasoned growers.
