Amnesia Jelly Automatic emerges from the long-running European love affair with citrus-forward, Haze-leaning sativas and the modern engineering of autoflowering genetics. Bred by Sensi Seeds, one of the Netherlands' most storied cannabis houses, it marries the cultural cachet of the 'Amnesia' family with the practicality of ruderalis-driven auto flowering. The name 'Jelly' nods to the cultivar's thick, glossy resin production—buds that feel almost gelatinous when fresh and densely cured.
Autoflowers rose to prominence in the late 2000s after early breakthroughs with Lowryder-type lines demonstrated that Cannabis ruderalis could transmit day-neutral flowering to photoperiod varieties. Over the past 15 years, breeders have progressively stacked potency, terpene density, and yield back into autos while preserving their rapid life cycle. Amnesia Jelly Automatic sits within this second or third wave of autos that can finish fast yet deliver sativa-style clarity and aroma.
In Dutch coffeeshops during the 1990s and 2000s, 'Amnesia' became shorthand for electric, lemony sativas that drew from the Haze family and other European selections. Though individual recipes varied by breeder and region, the effect profile was consistent: uplifted mood, creative drive, and a lingering, incense-like citrus. Sensi Seeds channeled this archetype into a format that flowers on its own timer, enabling growers at all latitudes to harvest a Haze-forward experience without chasing a long photoperiod crop.
Because many leading seed companies keep their autoflower recipes proprietary, you will not find a public datasheet that discloses every building block behind Amnesia Jelly Automatic. This is common across the industry; cannabis genealogy databases frequently mark entire branches as 'unknown' or 'proprietary' when breeders wish to guard competitive advantage. What matters to most growers and consumers is the execution: a reliable, day-neutral sativa with headroom, citrus, and resin in a compact, time-efficient package.
Genetic Lineage
Sensi Seeds identifies the heritage of Amnesia Jelly Automatic as ruderalis/sativa, signaling an auto-flowering backbone merged with a sativa-dominant aroma and effect set. In practical terms, that means a day-neutral flowering clock—typically switching from juvenile to reproductive growth by age rather than light schedule—while retaining the Amnesia family's lemony, incense-laced character. The exact parental plants are not publicly disclosed, but the phenotype suggests an Amnesia-type mother crossed and backcrossed with a stabilized ruderalis donor.
Within autoflower breeding programs, the ruderalis contribution often ranges from roughly 15% to 35% of the genome after multiple backcrosses, depending on how strongly the breeder selects for auto expression and how much they prioritize preserving the original cultivar's morphology and potency. Sensi Seeds has publicized similar approaches in related auto lines, combining carefully selected ruderalis parents with photoperiod elites to lock in day-neutral flowering while keeping the core chemotype intact. That framework fits the reported behavior of Amnesia Jelly Automatic: a sativa-leaning chemovar that finishes under extended light without 12/12 triggers.
To situate this variety among broader industry patterns, note that many modern autos echo classic Haze or Skunk influences in their upper canopy aroma. For example, some independent breeders blend Haze-forward autos with skunky lines to bolster yield and terp persistence; one commercial example pairs a Haze auto with a Skunk auto to inject citrus zing, illustrating a general strategy rather than a blueprint for this specific Sensi Seeds cultivar. Similarly, white-label autos in the market often describe balanced sativa/indica proportions with a ruderalis component—signals of the hybrid architecture that underlies most day-neutral releases.
Genealogy databases frequently catalog entire families of autos with incomplete or 'unknown' tagging, emphasizing how guarded these recipes remain. This is not unusual; even photoperiod classics sometimes sit behind partial lineage walls. For growers and patients, the more actionable data are the growth behaviors—height class, flowering duration, and vigor—and the resulting chemotype, which in the case of Amnesia Jelly Automatic aligns with high-THC, low-CBD sativa expectations.
Appearance
In the garden, Amnesia Jelly Automatic presents as a compact-to-medium sativa-leaning auto with a columnar main stem and symmetrical satellite branches. Internodes are moderately spaced, giving spears room to elongate without the extreme stretch seen in full-term Hazes. Under optimized indoor conditions, typical heights range from 60 to 110 cm, with occasional taller phenotypes when grown under very high PPFD and large root volumes.
Buds form as elongated, tapered colas with a high calyx-to-leaf ratio, making trimming efficient. The bracts swell late, stacking into torpedo-shaped clusters that maintain good airflow around the inflorescence. Pistils start a delicate cream to pale tangerine and darken to copper as the plant approaches its harvest window.
Trichome coverage is abundant, with bulbous capitate glands clustering tightly along calyx ridges and sugar leaves. Freshly cured flowers appear sugar-frosted, and the resin film gives an almost jelly-like tactile stickiness—hence the 'Jelly' moniker. Mature fan leaves display a sativa-leaning narrow leaflet with serrations that remain sharply defined well into senescence.
Coloration is primarily lime to forest green, sometimes with faint lavender hues when nighttime temperatures dip below 18–19°C late in flower. Because the structure remains moderately open, light penetrates deeper into the canopy, encouraging uniform secondary bud development. Even so, the main cola typically dominates total dry weight, a hallmark of auto-sativas bred for a single-apical architecture.
Aroma
Open a jar of Amnesia Jelly Automatic and the first impression is sharp citrus—fresh lemon zest and sweet orange peel layered over conifer and floral top notes. Beneath that, a classic Haze-like incense sits with hints of cedar, coriander, and faint anise. When the jar breathes, a peppery edge emerges, pointing to beta-caryophyllene, while subtle herbal sweetness suggests ocimene.
This cultivar's terpene expression amplifies after a slow cure of 14–28 days. During the first week of cure, fruit esters are bright and zesty; by week three, the bouquet becomes more cohesive and incense-forward. Properly dried flowers (58–62% RH in the jar) routinely present a room-filling profile within minutes of opening.
Grinding intensifies the citrus and reveals a deeper, resinous backbone—something like citrus marmalade spread over warm pine. Vaporizing at lower temperatures (170–180°C) emphasizes the lemon-zest and floral facets, while higher temperatures (190–200°C) bring the spice, wood, and faint diesel-like undertones forward. The overall impression remains clean and uplifting rather than heavy or skunky.
Because autos can lean slightly different across phenotypes, some plants push more toward sweet, candy-like citrus, and others toward drier, incense-dominant haze. Environmental factors—particularly sulfur availability and cure temperature—can shift the perceived balance between citrus brightness and peppered wood. Still, the signature remains unmistakably Amnesia: citrus plus incense with a refreshing, piney lift.
Flavor
On the inhale, expect a plate of lemon and sweet tangerine over a crisp, pine-lilted backbone. The mouthfeel is light and zesty at low temperatures and becomes more resinous and spicy at higher temperatures or deeper combustion. Many users notice a faint herbal sweetness that lingers on the tongue, reminiscent of lemon balm or lemongrass tea.
The exhale settles into classic Haze territory—incense, cedar, and a peppering of coriander seed—with a softly bitter citrus pith that keeps the finish dry. In joints and flower vaporizers alike, the flavor holds for several draws without collapsing into generic 'hashy' tones. This persistence is characteristic of terpinolene- and limonene-forward chemotypes when cured slowly.
Water-cured or heavily flushed flowers tend to highlight the citrus fraction at the expense of its spice and wood. Conversely, plants pushed with slightly higher late-flower potassium and meticulous drying at 18–20°C yield a richer, more incense-led finish. The overall sensory arc remains uplifting and clean, which aligns well with daytime or task-oriented consumption.
If extracting, cold-cured rosin captures the lemon zest and floral edges beautifully, while hydrocarbon extracts often accentuate the pepper and cedar. As always, the terpene balance is sensitive to temperature: keeping post-press or post-purge environments below 22°C helps preserve volatile monoterpenes that carry the top notes.
Cannabinoid Profile
Amnesia Jelly Automatic aligns with the Amnesia family's reputation for high THC and low CBD. According to aggregated user data on platforms like Leafly, Amnesia-type cultivars commonly test with high THC and minimal CBD, and users frequently report uplifting, creative, and euphoric effects. While exact laboratory figures vary by environment and phenotype, high-quality runs of auto-sativas today regularly fall in the 17–22% THC range, with top-of-batch results occasionally pushing above 23% under optimized LED and CO2 regimes.
CBD typically remains low, often below 0.5% by weight in flower, which centers the experience firmly in the THC-driven category. Minor cannabinoids such as CBG can appear in the 0.5–1.5% range, with traces of CBC and THCV occasionally detected in Amnesia-line phenotypes. These minor constituents can subtly modulate the effect, sometimes sharpening the energetic profile or smoothing the onset.
As with all cannabis, lab results will depend on harvest timing, drying conditions, and sample handling. Earlier harvests with mostly cloudy trichomes tend to produce a brighter psychoactive effect and may test slightly lower in total THC due to reduced decarboxylation of precursor acids in the drying process. Later harvests with more amber trichomes sometimes yield marginally higher total THC measurements but can tilt the effect toward a fuller-bodied relaxation.
Consumers sensitive to high-THC varieties should dose mindfully. Inhalation onset typically arrives within 2–5 minutes, peaks around 20–30 minutes, and sustains for 2–4 hours. Edible preparations made from this cultivar should be approached with caution, starting at 2–5 mg THC and titrating slowly, especially for those new to sativa-forward chemotypes.
Terpene Profile
The dominant terpene in Amnesia Jelly Automatic is often terpinolene, a hallmark of many Amnesia and Haze-descended chemovars. Terpinolene evokes citrus, pine, and floral aromas and commonly presents as the largest fraction in the terpene profile, sometimes accounting for 20–35% of total terpene content in comparable Amnesia-type analyses. Limonene follows closely in many phenotypes, supporting bright lemon-orange top notes and contributing to an uplifting perceived effect.
Supporting terpenes typically include beta-myrcene, beta-caryophyllene, and ocimene, with occasional contributions from linalool and humulene. In aggregate, total terpene content for well-grown, slow-cured sativa autos commonly lands between 1.2% and 2.0% by dry weight, though exceptional examples can exceed 2%. Within that total, a representative distribution might show terpinolene as the lead, limonene in the high-middle, and caryophyllene anchoring the spicy base.
Ocimene often confers the sweet, slightly herbal lift in the bouquet, and its volatility means careful drying is essential to retain it. Beta-caryophyllene, a sesquiterpene that binds to CB2 receptors, adds pepper and woody tones while potentially modulating the subjective body feel. Linalool, if present, softens the citrus with a mild floral note and can slightly temper racier edges in some sativas.
Environmental control changes terpene outcomes significantly. Keeping dry room temperatures at 18–20°C and relative humidity around 55–60% for 10–14 days reduces volatilization of monoterpenes like limonene and ocimene. Similarly, avoiding prolonged light exposure during cure preserves terpinolene, which degrades faster under elevated heat and UV.
Experiential Effects
Users gravitate to Amnesia Jelly Automatic for its bright, cerebral uplift that arrives cleanly and without heavy sedation. The onset is fast, often within a couple of minutes of inhalation, and a buoyant euphoria builds over the next 15–20 minutes. This mood lift is accompanied by a gentle sensory crispness—colors feel slightly brighter, and sounds seem more dimensional.
Leafly describes Amnesia as uplifting, creative, and euphoric, and those tags map closely to this cultivar's effect trajectory. Many users find it excellent for brainstorming, music appreciation, or social conversation, especially at low-to-moderate doses. Compared to indica-dominate autos, the 'couchlock' component is minimal, and the finish is clean rather than hazy.
Physically, most report only mild muscle relaxation with little to no heaviness behind the eyes. The energy is not jarring but rather sustained, making it a solid daytime option for errands, nature walks, or creative work. For some, appetite stimulation is modest, and the 'munchies' are less pronounced than with dessert-forward indica hybrids.
As with many high-THC sativas, dose management matters. Overconsumption can produce transient anxiety or a racing heart in susceptible individuals, particularly in unfamiliar settings or when dehydrated. Starting with a single small inhalation and waiting several minutes to assess is a prudent approach, especially for those new to sativa autos.
Potential Medical Uses
While individual experiences vary and cannabis is not a substitute for professional medical care, the profile of Amnesia Jelly Automatic aligns with potential daytime support for mood and motivation. Leafly characterizes Amnesia strains as uplifting, creative, and euphoric, which some patients with stress or low mood find beneficial. The limonene-terpinolene axis is often associated with bright, energizing perceptions that may help counteract fatigue during the day.
Users commonly report help with stress reactivity and situational anxiety at low doses, though higher doses can have the opposite effect. For those experiencing task-related lethargy or creative blocks, a small amount may increase engagement and cognitive 'flow.' The relatively low tendency toward sedation makes it a fit for conditions where daytime functioning is essential.
Some patients report relief from tension headaches or mild migraines, possibly owing to beta-caryophyllene's CB2 engagement and the anti-inflammatory potential of certain terpenes. Others mention mild appetite stimulation without heavy sedation, which can be useful for people seeking targeted appetite support that does not derail productivity. As always, responses are individual, and keeping a symptom and dosing journal can help quantify benefit.
For consumers sensitive to racy sativas, microdosing strategies—single inhalations spaced by 10–15 minutes—can provide mood support with fewer side effects. Those with panic disorders or cardiovascular concerns should consult clinicians and consider lower-THC options or balanced CBD:THC profiles. In all cases, start low, go slow, and avoid stacking multiple forms (e.g., inhaled plus edible) until you understand your response curve.
Comprehensive Cultivation Guide
Lifecycle and timing
Amnesia Jelly Automatic is a day-neutral cultivar that does not require a 12/12 light cycle to flower. Under standard indoor conditions, expect a total seed-to-harvest time of approximately 80–95 days, with some phenotypes finishing slightly faster or slower depending on environment. The flowering phase itself typically occupies 49–65 days of that life cycle, beginning naturally around day 21–28 from sprout.
Because you cannot extend the vegetative phase by adjusting light, maximizing early growth is critical. Start seeds directly in their final container to avoid transplant shock, which can set autos back several days and reduce final yield potential. Plan the entire run around the first four weeks, when root and canopy establishment set the ceiling for biomass and flower site count.
Germination and early care
Germinate in a damp starter cube or lightly moistened, pH-adjusted medium at 22–25°C with 90–100% humidity inside a covered dome. Most viable seeds pop within 24–72 hours; removing the dome as cotyledons fully open helps prevent damping-off. Under LEDs, keep seedlings at 250–400 PPFD, roughly 30–40 cm from a mid-power fixture, to avoid stretching.
Begin light airflow once the first true leaves emerge to strengthen stems. Water with a gentle ring around the seedling, keeping the core medium airy rather than saturated. Early feeding should be mild: EC 0.8–1.1 (400–550 ppm on a 500-scale), prioritizing calcium and magnesium to support rapid cell division.
Medium, containers, and transplanting strategy
Autos prefer an oxygen-rich root zone. For soil, blend a light, airy base (peat or coco-based) with 25–35% perlite and 5–10% biochar for structure. In coco/perlite or inert substrates, plan for more frequent fertigation and tighter EC control.
Use final containers from the start to prevent growth stalls. Indoors, 11–18 liters (3–5 gallons) are optimal for most tents; micro-grows can use 7–9 liters (2–2.5 gallons) with careful irrigation. Outdoors, 25–40 liters (7–10 gallons) or larger allow sufficient root volume for summer sun intensity and wind resilience.
Lighting and photoperiod
Although autos do not depend on light cycle to flower, they respond strongly to intensity and daily light integral (DLI). Provide 18 hours of light and 6 hours of dark (18/6) throughout for a balanced energy and recovery rhythm. Some growers push 20/4 for marginal gains in biomass; others prefer 18/6 to reduce heat and power draw.
Target PPFD by stage: 250–400 for seedlings, 400–600 for early vegetative, 600–800 for early flower, and 800–900 for mid-to-late flower if CO2 and nutrition are balanced. Without added CO2, many autos plateau in efficiency around 800–900 PPFD; beyond that, watch for photoinhibition. Aim for a DLI of roughly 25–30 mol/m²/day in early growth and 35–45 mol/m²/day in peak flower.
Climate and VPD
Maintain day temperatures of 24–27°C and night temperatures of 19–22°C for steady metabolism. Relative humidity can start at 65–70% in seedling stage, dropping to 55–60% in veg, 45–50% in early flower, and 40–45% in late flower. Track vapor pressure deficit (VPD) and aim for 0.8–1.2 kPa across the run to optimize stomatal function and calcium transport.
If running CO2 enrichment to 800–1,000 ppm, slightly higher canopy temperatures of 26–28°C can improve photosynthetic rates in late vegetative and early flower stages. Ensure strong air exchange and oscillating fans to prevent microclimates and reduce botrytis risk during dense cola formation.
Nutrition and EC management
Autos are often less tolerant of heavy nitrogen in early flower compared to photoperiods. In soil, feed lightly through week 3–4, allowing the amended medium to carry much of the load, then shift to a bloom-biased recipe. In coco/hydro, start at EC 1.2–1.4 in early veg and rise to 1.6–2.0 in mid flower, watching leaf color and tip burn as your feedback loop.
General NPK guidance: early veg around 3-1-2, transition at day 21–28 to 1-2-3, and peak bloom at 1-3-3 or 1-2-3 depending on cultivar appetite. Keep calcium and magnesium robust throughout, delivering 100–150 ppm Ca and 50–75 ppm Mg in solution, especially under LEDs. A low-dose silica supplement can fortify stems and reduce lodging in the main cola.
Irrigation strategy
Autos appreciate consistent, moderate moisture without waterlogging. In soil, water to 10–15% runoff when the pot feels roughly 50–60% of its saturated weight, typically every 2–4 days in mid-sized containers. In coco, smaller, more frequent irrigations—1–3 times daily in late veg/flower—help maintain a stable EC and root oxygenation.
Avoid large dry-backs that induce stress during the first four weeks, as autos cannot make up lost time. Conversely, chronic overwatering is the fastest route to stunting. Calibrate pot weight in your hands as a reliable, low-tech moisture gauge.
Training and canopy management
Low-stress training (LST) is the safest, highest-ROI approach for autos. Begin gentle tie-downs around day 14–18, bending the main stem laterally to expose lower sites without kinking. Reposition ties every few days to maintain an even canopy and prevent shade stacking.
Topping is possible but risky: if you choose to top, do it once at the 3rd or 4th node by day 18–21 and only on vigorous plants with zero stress history. Many growers skip topping entirely and rely on LST, soft supercropping, and selective defoliation. Remove only a few fan leaves at a time to improve airflow; excessive defoliation can stall autos.
CO2 and advanced optimization
If you run 800–1,000 ppm CO2 during peak light hours and hold PPFD around 850–900, expect slightly faster node development and thicker stems. Ensure nutrition and irrigation keep pace, as CO2-enhanced plants deplete substrate moisture more rapidly. Drop CO2 to ambient during dark periods to conserve gas and keep nighttime respiration balanced.
Pest and disease management
Integrated pest management (IPM) is most effective when preventive. Sticky cards, weekly leaf inspections, and regular canopy airflow reduce common threats like fungus gnats and spider mites. For soil grows, top-dressing with Bacillus thuringiensis israelensis granules at label rates helps suppress gnat larvae; beneficial nematodes can be layered in for heavy pressure.
During flower, avoid foliar sprays that could mar buds or trap moisture in dense colas. If powdery mildew risk rises, dehumidify promptly and increase canopy airflow; sulfur burners should be used only before flower sets to avoid damaging terpenes. Companion plantings—basil, marigold, dill—can assist with beneficial insect attraction outdoors, enhancing biological control.
Outdoor considerations
Amnesia Jelly Automatic thrives in full sun with at least 6–8 hours of direct light. In temperate zones, multiple successive plantings allow two or three harvests per season, leveraging the 80–95 day lifecycle. Select a sheltered location to mitigate wind stress on tall colas and stake plants early to prevent lodging in late-season storms.
Outdoor containers of 25–40 liters (7–10 gallons) balance portability and root volume. In-ground beds with amended soil can push taller plants and larger colas, but be diligent about drainage. If nights drop below 12°C in early spring or late fall, consider a lightweight cover to buffer temperature swings that can slow growth.
Yield expectations
Yield depends on light intensity, container size, and environmental control. Indoors under efficient LEDs, experienced growers commonly report 350–500 g/m² with multiple plants per square meter and disciplined LST. Single-plant runs in 11–18 liter pots often produce 60–120 g dry flower per plant under 18/6, with standout phenotypes exceeding that range when given high PPFD and CO2.
Outdoors, expect 50–150 g per plant depending on sun hours, pot size, and seasonality. Because autos cannot recover vegetative time lost to stress, the first 30 days are decisive for final yield. Even small improvements in early vigor—correct PPFD, gentle irrigation, and warm root zones—compound into larger, denser colas at harvest.
Harvest timing and trichome assessment
For a classic, energetic Amnesia expression, harvest when trichomes are mostly cloudy with only 2–5% amber. This timing preserves brighter monoterpenes and keeps the effect crisp. If you prefer a slightly rounder body finish, wait for 8–12% amber, understanding that terpene brightness may soften.
Use a 60–100x loupe to inspect glands across multiple buds, focusing on mid-canopy flowers unaffected by microclimate extremes. Pistil color is a rough guide; trichomes are the final arbiter. Plan a staggered harvest if top colas ripen faster than lowers; autos tolerate this well if the plant remains healthy.
Drying and curing
Hang whole plants or large branches in a dark room at 18–20°C and 55–60% RH with gentle airflow for 10–14 days. Aim for a slow, even dry that preserves terpinolene and limonene, both of which are highly volatile above 22°C. When small stems snap and larger stems bend with a soft crack, move to jars for cure.
Jar at 62% RH initially, then gradually settle to 58–62% over the first week, burping daily for 5–10 minutes to vent moisture and CO2. Continue curing for 2–6 weeks; the bouquet will knit from bright citrus into a more sophisticated citrus-incense harmony. Properly cured flower maintains flavor density and smoother smoke, and it stores longer without terpene collapse.
Post-harvest handling and storage
Store cured jars in a cool, dark environment at 15–18°C to slow terpene oxidation. Avoid temperature spikes and UV exposure, both of which accelerate aromatic loss. For long-term storage beyond six months, consider vacuum-sealed, nitrogen-flushed containers and keep them near 10–12°C.
Grinding just prior to use rather than pre-grinding helps retain the top note citrus volatiles. If producing concentrates, process fresh-frozen material for live products to capture maximum monoterpenes, or cold-cure rosin at 15–20°C to stabilize the lemon-forward profile. Handling gently at every step rewards you with the 'jelly' resin texture and an aroma that announces itself from across the room.
Contextual notes on autoflower genetics
Across the autoflower category, many breeders combine haze-forward autos with skunky or heavy-yielding frames to balance vigor and terp stability—examples in the market reflect this strategy without revealing proprietary recipes. Some hybrids list approximate sativa/indica proportions with a ruderalis contribution, underscoring that 'auto' is a trait layered onto classical cannabis lineages. Genealogy databases often mark portions of these breeding trees as 'unknown' or 'undisclosed,' which is typical for competitive seed markets.
For Amnesia Jelly Automatic specifically, Sensi Seeds' ruderalis/sativa designation and Amnesia effect alignment are the practical guideposts. The result is a cultivar that honors the uplifting, creative arc described in Amnesia strain literature while simplifying the grower's calendar. Delivered as an auto, it opens the door to Haze-like citrus incense even for small-space growers on an 18/6 schedule.
