Amnesia Bilbo Auto is the autoflowering expression of a celebrated Basque selection of Amnesia refined by Genehtik Seeds, a breeder long associated with Bilbao’s “Bilbo” genetics. The Bilbo tag signals a Spanish lineage of stabilized, production-minded cultivars, and Amnesia Bilbo was one of the phenotypes adapted for high resin output and a classic Haze profile. To convert it into an autoflower, Genehtik crossed the photoperiod Amnesia Bilbo with robust ruderalis lines, then backcrossed to preserve the sativa-forward character while locking in auto-flowering behavior.
The strain sits at the intersection of tradition and modernity: an Amnesia-derived core reinterpreted through the lens of contemporary auto breeding. Industry roundups in recent years have emphasized that top-selling autos deliver dense, trichome-encrusted buds with a notably fast-hitting effect profile. Amnesia Bilbo Auto aligns with that modern expectation, pairing fast lifecycle convenience with an old-school incense-and-citrus personality.
Amnesia Bilbo Autoflowering is present in public strain indexes and retail sitemaps, which attests to its recognition among European and global growers. Genehtik’s broader reputation in Spain—shaped partly by the success of Bilbo-labeled genetics—gives this auto a strong pedigree appeal. In short, the strain was engineered to bring the unmistakable Amnesia experience to an 11–12 week seed-to-harvest format without sacrificing intensity.
The momentum behind autoflowers has accelerated since 2020, with breeders consistently reporting stronger potency and better stability. Blog features and seed reviews from 2023–2025 describe autos that are easier to grow, faster to finish, and often totally covered in trichomes, reflecting a multi-year refinement of ruderalis hybrids. Amnesia Bilbo Auto is a product of that wave, benefiting from the improved vigor, resin production, and consistency that define current-generation autos.
Genetic Lineage and Heritage
The ancestry is best summarized as ruderalis/indica/sativa, with the sativa component derived from an Amnesia lineage (Haze family) and the indica/ruderalis components introduced to control growth, accelerate flowering, and add density. Amnesia lines commonly trace to Southeast Asian, Jamaican, and Afghani roots, giving a complex terpene and cannabinoid backdrop. In Amnesia Bilbo Auto, Genehtik preserved the energetic headspace while adding compact structure and a time-efficient lifecycle via ruderalis.
From a phenotypic standpoint, expect a sativa-leaning effect paired with a medium-stout auto morphology driven by indica and ruderalis influence. Internode spacing tends to be moderate, and apical dominance remains clear, although side branching is productive with training. The result is a balanced plant that sits comfortably between slender Haze expressions and the squat bushiness of heavier indica autos.
The Bilbo designation also speaks to Spanish breeding priorities: reliable indoor performance, good yield per square meter, and resin-coated flowers suitable for both smoking and extraction. Compared with many Hazes, the Bilbo selection generally shows tighter calyx clusters and improved bud hardness. Those traits translate well into the auto version, where consistent density and a simplified feeding curve are especially valued by new growers.
While exact percentage splits vary from phenotype to phenotype, many growers describe this cultivar as sativa-forward in effect but hybrid in growth. The ruderalis input ensures photoperiod independence and a fixed life clock, meaning it will flower automatically after a short juvenile window. This genetic design provides harvest predictability across latitudes and grow spaces.
Appearance and Plant Structure
Amnesia Bilbo Auto typically reaches 70–110 cm indoors, with most phenotypes clustering around 80–95 cm in 11–15 liter containers. Plants present with a strong central cola and 6–10 productive laterals, each carrying stacked calyces. Leaf morphology ranges from medium-wide hybrid fans in early growth to narrower sativa-esque blades in mid-flower.
Bud formation is notably compact, with high calyx-to-leaf ratios that simplify trimming and increase the jar appeal per gram. Flowers often display a glassy layer of glandular trichomes that gives the surface a frosted, crystalline appearance under light. This trait is consistent with modern autos highlighted in 2023 industry lists that praised dense, hard buds with a thick trichome crust.
Coloration is vibrant lime to forest green during mid-flower, sometimes showing sunset hues if nighttime temperatures drop by 5–7°C in late bloom. Pistils begin cream to orange and can darken to amber or copper as maturity approaches. The overall look is of symmetrical, resin-swollen towers rather than airy Haze spears.
Stem thickness is above average for a sativa-leaning auto, thanks to the indica/ruderalis contribution to lignification. With proactive low-stress training, the plant builds an even canopy with numerous medium-sized colas instead of a single dominant spear. This translates into more uniform bud size and weight at harvest.
Aroma and Flavor
The aromatic signature leans citrus-incense with sweet herbal undertones and a pepper-spice finish. On the plant, rub the stem or a sugar leaf and you will encounter zesty lemon, cedar, and a whiff of floral soap that is typical of Amnesia-type terpenes. As flowers cure, the incense becomes more pronounced, and a subtle sweetness emerges that softens the sharper notes.
Flavor on inhalation centers on lemon zest, lime peel, and dry wood, followed by a classic Haze incense and a clean, slightly floral exhale. Vaping at 175–185°C accentuates terpinolene-driven citrus and light floral tones, while higher temperatures (190–200°C) bring out peppery caryophyllene and earthy myrcene. In joints or pipes, the smoke is surprisingly smooth for a Haze-leaning profile when properly cured to 62% relative humidity.
The aftertaste lingers as lemon-oil and faint anise, with a resinous mouthfeel attributable to abundant trichome heads. Many users also note a green mango or sweet basil echo after exhale, hinting at ocimene and limonene in the blend. Because of the tight flower structure, longer dry times (10–14 days) help preserve top-notes by reducing chlorophyll bite.
Aromatics intensify markedly during the final two weeks of flowering, often prompting the need for robust carbon filtration. Expect room-filling terpenes when plants are agitated, defoliated, or during trimming. Odor control is essential if discretion is a priority.
Cannabinoid Profile and Potency
While lab-verified numbers vary by phenotype and cultivation, Amnesia Bilbo Auto commonly tests as a high-THC, low-CBD cultivar. Well-grown autos in this family routinely occupy the 16–22% THC range, with occasional top-tier phenotypes reaching the mid-20s under optimized lighting and nutrition. CBD is usually below 1%, and total cannabinoids often fall between 18–26%.
Minor cannabinoids can include CBG in the 0.3–1.0% band and trace CBC, which may subtly modulate the headspace. The potency profile tracks with consumer reports that the effects land quickly and decisively—consistent with industry commentary that modern autos tend to hit hard and fast. That rapid onset aligns with the strain’s dense resin and terpene synergy.
For dosing context, a single 0.25 g vaporizer bowl at 18% THC contains roughly 45 mg of THC; typical inhaled delivery efficiency ranges 20–40%, translating to an absorbed dose of 9–18 mg. Newer users often find 2–5 mg sufficient for noticeable uplift, while experienced users may prefer 10–20 mg for full effects. Titration is essential because the sativa-style onset can feel intense if over-consumed.
Across grows, consistent environmental control and adequate light intensity correlate strongly with potency. Under 800–1,000 µmol·m⁻²·s⁻¹ flowering PPFD and balanced nutrition, autos like this routinely achieve their upper potency ranges. Suboptimal lighting, overwatering, or nitrogen-heavy feeding late in bloom can depress cannabinoid accumulation by several percentage points.
Terpene Profile and Chemistry
Amnesia heritage frequently expresses a terpinolene-forward bouquet supported by myrcene, beta-caryophyllene, ocimene, and limonene. In practice, total terpene content for well-cultivated autos of this type often falls in the 1.5–3.0% range of dry weight. Within that, terpinolene may occupy 0.3–0.8%, myrcene 0.2–0.6%, beta-caryophyllene 0.2–0.5%, limonene 0.2–0.4%, and ocimene 0.1–0.3%, with additional trace contributors like linalool and humulene.
Terpinolene is linked to the citrus-incense top-note and bright, effervescent headspace often associated with Amnesia phenotypes. Beta-caryophyllene, a CB2 receptor agonist, contributes pepper-spice and may add a calming, body-oriented counterweight to the energetic start. Myrcene provides herbal depth and can aid diffusion of other terpenes, while limonene adds lemon zest and mood-elevating character.
Ocimene is a likely source of the sweet, slightly tropical lift that some tasters describe as green mango or sweet basil. At higher vaping temperatures, the peppery edges of caryophyllene become more pronounced, shifting the flavor into a woodier, spicier register. This thermal sensitivity is why temperature control can dramatically change how the strain tastes and feels.
Total terpene preservation benefits from careful post-harvest practices. Drying at 18–20°C with 55–60% RH for 10–14 days can reduce terpene loss compared with faster, warmer dries; studies on volatile retention suggest significant evaporation when temperatures exceed the mid-20s Celsius for prolonged periods. Slow curing in airtight containers at 62% RH further rounds the profile over 3–6 weeks.
Experiential Effects
The onset is swift—often within 1–3 minutes by inhalation—delivering a bright, clear rush to the forehead and behind the eyes. Users report a buoyant mood, heightened curiosity, and a mild sensory enhancement that makes music and conversation engaging. The first 30–60 minutes tend to be cerebral and uplifting, with a crisp focus when dosed modestly.
As the session progresses, a warm, body-light relaxation folds in without heavy sedation, reflecting the hybrid base. At moderate doses, many people experience sustained motivation and an easy sociability suitable for daytime or early evening. At higher doses, the stimulation can tip toward racy, so pacing and hydration are your friends.
Consistent with modern auto reports, the effects feel decisive: the strain hits with purpose, then settles into a steady groove. Creative brainstorming, outdoor walks, and chores pair well with the initial headspace. Toward the tail end, a gentle afterglow remains for 60–120 minutes, often with a hunger bump.
Common side effects include dry mouth and dry eyes; occasional users sensitive to strong sativas may encounter transient anxiety or a rapid heart rate, especially when stacking hits. Lower-temperature vaporization and smaller first draws help manage intensity. As always, set and setting matter—this profile is best in relaxed, familiar environments for newcomers.
Potential Medical Uses
Nothing in this section substitutes for medical advice, but the profile suggests potential utility for certain symptom clusters. The upbeat onset and limonene-rich citrus character may assist with low motivation or situational low mood, particularly in the morning. Users often report improved focus on routine tasks when using conservative doses.
Mild to moderate pain relief can arise from the caryophyllene content and overall THC level, though this is not a heavy sedative. Tension-related headaches sometimes respond to a combination of distraction, vasodilation, and muscle easing—a pattern anecdotal users attribute to sativa-leaning hybrids. For neuropathic tingling, the quick onset can provide prompt relief, albeit often shorter-lived than with heavier indica profiles.
Appetite stimulation is common in the comedown, which could be helpful for those with poor appetite. Nausea relief is frequently associated with inhaled THC, and fast-acting autos like this can be useful in acute episodes where oral onset is too slow. However, the stimulating top note means it may not be ideal for individuals who are anxiety-prone or highly sensitive to sativa energy.
Practical dosing tactics include microdoses of 2.5–5 mg THC by vaporization, stepped up only as needed. Daytime therapeutic use often benefits from short, controlled sessions with a 60–90 minute evaluation window before redosing. Patients concerned about anxiety can prioritize lower-temperature vapor paths and terpinolene-leaning phenotypes balanced by caryophyllene.
Comprehensive Cultivation Guide
Lifecycle and timing: Most Amnesia Bilbo Auto phenotypes finish in 75–85 days from seed indoors, with fast individuals at 70–75 days and fuller expressions needing up to 90. Outdoors, expect 80–95 days depending on temperature, day length, and cloud cover. Compared with some 10-week autos reported in budget-friendly skunk lines, this cultivar generally benefits from an extra week for full terpene development.
Seedling stage (days 0–10): Start seeds directly in their final containers (9–15 liters for soil; 11–18 liters for coco) to avoid transplant shock, which can cost 3–7 days of growth in autos. Maintain 24–28°C canopy temperature, 70–75% RH, and 250–350 µmol·m⁻²·s⁻¹ PPFD for compact, healthy starts. pH 6.0–6.2 (coco) or 6.2–6.5 (soil); EC 0.4–0.8 with only mild root-stimulants.
Juvenile and early veg (days 10–25): Increase light to 400–600 PPFD with an 18/6 or 20/4 schedule. Keep RH 60–65% and a gentle VPD of 0.9–1.1 kPa to drive leaf expansion without stress. Begin LST around day 14–18 when the fourth node is present, bending the main to encourage 6–10 even tops.
Preflower and stretch (days 25–40): Plants enter preflower automatically; boost PPFD to 700–800 and shift VPD to 1.1–1.3 kPa. In coco, run EC 1.2–1.6; in soil, move to full-strength flower nutrition as pistils appear. Limit defoliation to targeted leaf plucks that uncover budsites—over-defoliation can slow autos noticeably.
Flowering (days 40–75+): Hold PPFD at 800–1,000 if CO2 is ambient; if you supplement to 900–1,000 ppm CO2, PPFD can rise to 1,100–1,200 for advanced growers. Maintain 24–26°C day and 20–22°C night, RH 50–55% early bloom, 45–50% mid bloom, and 42–45% late bloom to reduce botrytis risk in dense colas. Feed at EC 1.6–2.0 in coco and avoid excessive nitrogen after week five of life to optimize resin and terpene output.
Water and media: In soil, allow the top 2–3 cm to dry between waterings; in coco, irrigate daily to 10–20% runoff once root mass is established. Autos dislike overwatering—aim for container weights that rebound within 24 hours. Cal-mag supplementation is often necessary under high-intensity LEDs; 0.5–1.0 mL/L is typical depending on base nutrients.
Training: LST and strategic tucking are the safest. Topping can work only if done very early (around day 14–16) on vigorous individuals and followed by excellent care; otherwise, skip it. A simple tie-down of the main and two or three subsequent adjustments usually yields a level canopy and 8–12 primary colas.
Pest and pathogen management: Dense, resinous autos benefit from proactive IPM. Sticky traps, beneficial mites (e.g., Amblyseius swirskii for thrips/whiteflies), and weekly neem/karanja leaf wipes during veg are effective, stopping foliar sprays by early flower. Keep intake filters clean and avoid floor clutter to reduce fungus gnat and powdery mildew pressure.
Lighting and DLI: Over the life cycle, target a daily light integral around 35–45 mol·m⁻²·day⁻¹ in mid-flower for robust yields without light stress at ambient CO2. If leaves canoe or chlorosis appears on upper fans, reduce intensity by 10–15% or raise the fixture 5–10 cm. An 18/6 schedule balances energy savings with strong growth; 20/4 can speed vegetative mass slightly in the first month.
Nutrient strategy: A general N-P-K progression of 2-1-2 in veg transitioning to 1-2-3 in bloom works well, with heightened magnesium during weeks 4–7 of life. Monitor runoff pH weekly; drifting below 5.8 in coco or above 6.8 in soil can lock out key cations. Consider a mild carbohydrate additive and amino acids in mid-flower to support microbial and plant metabolism.
Environmental fine-tuning: Maintain steady airflow with 0.5–1.5 m/s leaf surface velocity and oscillating fans to break boundary layers. Dehumidification capacity should be sized to remove 1–2 liters per m² per day at peak transpiration. Keep night-to-day temperature differentials around 3–5°C to avoid excessive stretch or terpene volatility.
Yield, Harvest Timing, and Post-Processing
Yield indoors typically ranges 350–500 g/m² under 600–700 W of quality LED in a 1.2 × 1.2 m tent, with skilled growers surpassing 550 g/m² using CO2 and optimized irrigation. Single-plant yields in 11–15 L containers commonly hit 50–120 g, with standout phenotypes exceeding 150 g under high PPFD and careful training. Outdoors, expect 40–120 g per plant in temperate climates and more in long-summer zones.
Harvest timing is best judged by trichomes rather than breeder estimates. For a bright, energetic effect, harvest around 5–10% amber trichomes with mostly cloudy; for a slightly heavier finish, wait for 10–20% amber. Pistil color is a secondary indicator—aim for 80–95% browned pistils paired with swollen calyces.
Flushing strategies vary by medium. In coco, a 7–10 day reduced-EC finish (0.2–0.4 over base water) can clear residual salts; in soil, a gentle taper over 10–14 days protects root microbiology while leaning out nitrogen. Water-temperature and pH consistency during the final two weeks helps avoid late stress and foxtailing.
Post-harvest, dry at 18–20°C and 55–60% RH with steady airflow for 10–14 days, then jar cure at 62% RH. Burp daily for the first week, then every other day for the second, and weekly thereafter for 4–6 weeks. Proper curing can raise perceived aroma intensity by 20–40% and smoothness markedly, preserving the lemon-incense identity.
Positioning Among Modern Autoflowers
Auto breeding over the last several years has delivered faster cycles and stronger resin production across the board. Industry blogs highlighting best-selling autos in 2023 emphasized hard, compact buds and an immediate, potent effect—traits that Amnesia Bilbo Auto exemplifies. Reviews from 2025 continued the theme of autos being easy, fast, and coated in trichomes, reflecting stability that growers have come to expect.
Against that backdrop, Amnesia Bilbo Auto stakes out the classic Haze-adjacent niche with a cleaner, more cerebral headspace than many dessert or cookie-influenced autos. Compared with skunk-derived autos that sprint from seed to harvest in about 10 weeks, Amnesia Bilbo Auto can benefit from an extra week for terpene depth. The trade-off is a more layered citrus-incense bouquet and an energetic, creative lift.
The Bilbo connection also situates this cultivar within a Spanish lineage prized for reliability and production. Spanish-bred genetics have influenced multiple European seed houses, with Bilbo lines appearing even in unrelated catalogs as points of reference. Growers who want a familiar Amnesia experience without photoperiod management find this auto an attractive, time-efficient substitute.
