Amnesia Bilbo is a mostly sativa cannabis cultivar developed by Genehtik Seeds, a well-regarded Basque breeder based in Spain. The name nods to Bilbo, the Basque-language name for Bilbao, signaling the plant's Iberian selection history and performance under Western European conditions. Growers and consumers prize it for its bright citrus-haze bouquet, vigorous stretch, and electric, cerebral high.
Within the Amnesia family tree, Amnesia Bilbo has earned recognition alongside classics like Amnesia Haze and newer offshoots. CannaConnection's sitemap, for example, lists both Amnesia Bilbo and Amnesia Bilbo Autoflowering, situating it among notable Amnesia derivatives and variants. That visibility reflects years of popularity in Spanish social clubs and European gardens.
In practical terms, Amnesia Bilbo is a high-energy daytime strain with strong potency and rich terpenes. It often rewards experienced cultivators with substantial yields and exceptional resin density for a sativa-leaning plant. For connoisseurs, it offers a layered flavor that evolves from lemon-peel to incense and spice as the joint or vaporizer session progresses.
History and Breeding Context
Genehtik Seeds emerged from Spain's vibrant cannabis scene, focusing on stabilizing elite clones and adapting winning genetics to local climates. Amnesia Bilbo represents Genehtik's Basque-influenced selection of the Amnesia lineage, aiming for robust growth, reliable yields, and a signature haze profile that performs well in temperate, maritime regions. The selection likely prioritized mildew tolerance and flower density calibrated to longer flowering windows typical of sativa-dominant plants.
The broader Amnesia story traces to Dutch breeding hubs of the 1990s and 2000s, where Haze-influenced polyhybrids intersected with Skunk and Afghan lines. Many Amnesia phenotypes share ancestry with Haze, Northern Lights, and Skunk, explaining their spicy-citrus terpenes and energetic dynamics. Genehtik's work refined this complex background, seeking a phenotype that retained punchy citrus-haze notes while improving garden manageability.
By the early 2010s, Spanish social clubs and European home-growers had embraced Amnesia Bilbo for its euphoric profile. Reports from Spanish grow journals highlighted long, candle-shaped colas and a satisfying combination of heady uplift with a calm landing. Over time, autoflowering versions appeared in catalogs and on portals such as CannaConnection's sitemap, expanding access for growers seeking faster cycles.
Genetic Lineage and Phenotypic Footprint
While Genehtik Seeds has not disclosed a precise pedigree formula, Amnesia Bilbo sits squarely in the Amnesia/Haze family. This implies a polyhybrid background blending tropical sativa heritage with indica stabilizers from classic lines like Northern Lights and Afghan. The practical result is a mostly sativa genotype with a predictable stretch and vigorous lateral growth.
Phenotypically, expect a vertical architecture with internodal spacing that is medium to long, especially under high-intensity lighting. Plants tend to stretch 1.5–3.0x after the switch to 12/12, a statistic frequently reported for Amnesia-type sativas in indoor gardens. Leaves lean toward a narrow-lobed shape, with a lighter green hue indicating active nitrogen metabolism during mid-veg.
Flower morphology typically produces elongated, stacked spears rather than golf-ball clusters. Calyx-to-leaf ratios are favorable, with resin heads accumulating densely by week 7 of bloom and swelling through weeks 9–11. The genotype readily expresses a terpinolene-forward terpene bouquet, which often correlates with citrus, pine, and floral-incense notes in sensory evaluations.
Appearance and Plant Morphology
In vegetative growth, Amnesia Bilbo displays a bright, vibrant green with slender petioles and flexible stems, making it responsive to low-stress training. The canopy naturally wants to rise vertically, but it fills a screen quickly when topped once or twice. Side branches are productive and can be coaxed into even canopies with simple tie-downs.
During flowering, the plant showcases elongated colas with tapering tips, common in sativa-dominant lines. The calyxes stack in a way that creates airy yet substantial spears, often reducing mold risk compared to ultra-dense indica flowers. Resin glands appear early, and by week 7 the buds exhibit a frosted, glassy sheen under grow lights.
Coloration at maturity can include lime-to-emerald flowers flecked with orange stigmas, sometimes blushing slightly under cooler night temperatures. Trichomes are abundant, with a mixture of capitate-stalked heads that hold their shape well for dry-sifting or ice water extraction. When properly dialed in, yields of 450–600 g/m² indoors are attainable, with outdoor plants often topping 600–1200 g per plant in favorable climates.
Aroma Profile
Aromatically, Amnesia Bilbo leans into a classic haze character dominated by citrus-peel brightness and sweet herbal spice. Many noses detect lemon zest up front, followed by pine and an airy, incense-like top note. Beneath that, faint basil and anise hints sometimes appear as the flowers cure beyond 30 days.
Breaking a cured bud unleashes sharper terpenes, with terpinolene and limonene often asserting themselves. The aroma can shift from fresh to peppery-sweet as beta-caryophyllene and ocimene volatilize. In jar tests, total terpene content in Amnesia-type profiles commonly falls between 1.5% and 3.0% by weight, a range consistent with potent, aromatic sativas.
The nose remains stable during a proper cure, retaining high-toned citrus when stored at 58–62% relative humidity. Over-drying below 55% RH can flatten the citrus and emphasize woody notes, so gentle humidity control helps preserve the signature bouquet. When ground, the fragrance becomes expansive, filling a room quickly, a trait mentioned frequently by club patrons and home-growers.
Flavor and Mouthfeel
On the palate, Amnesia Bilbo presents an immediate lemon-lime tang that rides on a smooth, incense-like vapor. Expect a clean, piney exhale with a trailing sweetness reminiscent of candied citrus peel. Subtler tasters may register notes of lemongrass, white pepper, and faint floral tones.
Combustion yields a surprisingly smooth smoke for a sativa-forward flower when properly flushed and cured. Vaporization at 180–195°C accentuates terpinolene and limonene, delivering a fresh, sparkling profile without harshness. As the session proceeds, the flavor deepens into a herb-spice character, showing caryophyllene's pepper warmth.
Mouthfeel is light and effervescent rather than creamy, aligning with its uplifting effect profile. Prolonged storage beyond 60 days of cure can introduce sandalwood, tea, and faint resinous undertones as terpenes rearrange. For flavor-focused users, small, frequent grinds preserve the citrus top notes best.
Cannabinoid Profile and Potency
Amnesia Bilbo is generally potent, with THC commonly reported in the 18–22% range and occasional phenotypes testing higher. CBD typically remains below 1%, often measuring between 0.1% and 0.6% in sativa-dominant Amnesia selections. CBG can appear in modest quantities, frequently around 0.3–1.0%, depending on maturity at harvest.
Users and lab summaries for Amnesia-type cultivars indicate robust psychoactivity with rapid onset. In consumer surveys and dispensary data, high-THC sativas are associated with strong head-oriented effects and increased perceived energy. This aligns with Amnesia Bilbo's reputation as a daytime strain that can be intense for novices.
From a effects-per-milligram perspective, higher terpene loads may potentiate subjective intensity. Studies suggest that terpene totals near or above 2.0% can modulate THC experience, improving perceived flavor and altering onset dynamics. For most users, 1–2 inhalations deliver noticeable effects within minutes, with peak intensity at 20–40 minutes and a 2–3 hour duration.
Terpene Profile and Volatile Chemistry
The dominant terpene fingerprint for Amnesia Bilbo is commonly terpinolene-forward, with limonene, beta-myrcene, and beta-caryophyllene in supporting roles. Reported ranges for analogous Amnesia phenotypes suggest terpinolene at 0.3–0.9% by weight, limonene at 0.2–0.6%, and myrcene at 0.2–0.8%. Caryophyllene often registers 0.1–0.4%, adding the peppery-spice that rounds out the profile.
Secondary volatiles such as ocimene, linalool, and humulene frequently appear in trace-to-moderate levels. Ocimene contributes the sweet-herbal lift, while linalool offers floral softness that becomes more noticeable with longer cures. Humulene can underline woody-herbal elements and has been associated with a subtle dryness on the palate.
Total terpene content typically lands between 1.5–3.0% for well-grown specimens, with elite cuts and optimized grows occasionally surpassing 3%. Environmental factors, harvest timing, and curing discipline have outsized effects on this range. Harvesting when trichomes are mostly cloudy with 5–10% amber often preserves top-note terpenes more effectively than waiting for 20%+ amber.
Experiential Effects and User Reports
Amnesia Bilbo delivers a fast-rising cerebral buzz marked by heightened focus, uplift, and an outgoing mood. Users often describe a bright, sparkling quality that pairs well with creative work, social activity, or exercise. The onset is typically brisk, aligning with high-THC sativas where effects are felt within minutes.
As the session unfolds, the high can become immersive and expansive, with sensory enhancement and a sense of mental clarity. Some users report a racing edge when dosing rapidly, so paced inhalation can help shape a cleaner arc. The comedown tends to be gentle, with a light physical relaxation that does not sedate most people.
In community reviews, 65–80% of respondents characterize the experience as energizing or uplifting, with 20–35% noting a potential for intensity in higher doses. Dry mouth and dry eyes are the most common side effects, followed by occasional transient anxiety for sensitive users. Pairing with hydration and mindful dosing reduces discomfort while preserving the strain’s productive qualities.
Potential Medical Uses and Considerations
Patients seeking daytime relief often turn to sativa-leaning profiles for mood, motivation, and fatigue-related symptoms. Anecdotally, Amnesia-type cultivars are reported to help with low mood, stress, and focus challenges due to their energizing and clarifying effects. The citrus-terpinolene-limonene signature correlates with user reports of uplift and alertness.
For pain, this cultivar offers moderate head-level distraction and may help with tension-type discomforts. Neuropathic or severe chronic pain conditions may require additional cannabinoids or balanced ratios. The low CBD content means users looking for anti-inflammatory support may consider adjunct CBD products.
Common adverse effects include dry mouth, dry eyes, and in higher doses, transient anxiety or a racing heart. Patients with anxiety disorders should begin with low doses and slow titration to assess tolerability. As with all cannabis use, individual responses vary, and medical decisions should be made with a healthcare professional's guidance.
Comprehensive Cultivation Guide
Growth difficulty for Amnesia Bilbo is moderate, owing to its sativa stretch and longer bloom window of approximately 65–75 days indoors. Outdoor finishes typically land in late October in the Northern Hemisphere, making site selection and weather planning vital. The plant rewards training and environmental control with high-quality yields and consistent resin production.
Environment: Maintain daytime temperatures of 24–28°C in veg and 22–26°C in flower, with a 3–5°C night drop. Relative humidity targets are 65–70% for seedlings, 50–60% in veg, 45–55% in early flower, and 40–50% late flower. Aim for VPD of 0.8–1.1 kPa in veg and 1.2–1.5 kPa in bloom to balance transpiration and disease resistance.
Lighting: In veg, 300–600 µmol/m²/s PPFD with an 18/6 or 20/4 photoperiod establishes robust growth. In flower, 700–1000 µmol/m²/s PPFD is a productive range, with advanced growers pushing 1000–1200 µmol/m²/s alongside 800–1200 ppm CO2. Daily light integrals of 30–45 mol/m²/day in veg and 40–60 mol/m²/day in flower are effective targets.
Media and pH: In soil, maintain pH 6.2–6.8; in coco/hydro, 5.8–6.2. A 70/30 coco-perlite blend supports rapid root development and high oxygenation for sativa vigor. Organic soil growers can succeed with a living soil amended with balanced inputs and regular top-dressing.
Nutrition: Feed EC 1.2–1.6 mS/cm in veg and 1.6–2.2 mS/cm in bloom, adjusting to cultivar appetite. Nitrogen demand is steady through week 2 of flower, tapering thereafter as phosphorus and potassium take precedence. Sativa lines often show magnesium and calcium hunger; plan for 100–150 ppm Ca and 50–80 ppm Mg during mid-bloom.
Training and canopy: Top once at the 5th node, then low-stress train to widen the plant and improve light distribution. A single or double SCROG net is ideal to control a 1.5–3.0x stretch after flip. Avoid high-stress techniques past day 10 of flower to prevent stall or nanners.
Irrigation: In coco, small, frequent feeds with 10–20% runoff stabilize EC and root-zone pH. In soil, allow the top 2–3 cm to dry before watering, targeting a wet-dry rhythm that finishes with pots lighter but not bone-dry. Automated drip at 2–6 irrigations per light-on cycle can optimize uptake under higher PPFD.
Defoliation and airflow: Remove lower growth that will never reach the canopy in late veg and day 21 of flower. Maintain 0.3–0.5 m/s canopy airflow and 8–15 total air exchanges per hour in tent or room. Proper pruning keeps spears airy and reduces botrytis risk during the final weeks.
Pest and disease management: Because flowering is longer, integrated pest management should begin early. Use yellow sticky cards, weekly scouting, and preventative biologicals like Bacillus subtilis and Trichoderma for pathogen suppression. For pests, rotate neem or azadirachtin in veg with Beauveria bassiana or horticultural oils, discontinuing oil sprays by early flower.
Scheduling: A common indoor schedule is 4–5 weeks veg followed by 9–11 weeks flower. Flip at 60–80% of target canopy fill to account for stretch into the SCROG. Outdoor growers should start seeds indoors by March–April (Northern Hemisphere), transplant after last frost, and support branches by mid-September.
Yield optimization: With dialed environmental control and training, indoor yields of 450–600 g/m² are realistic. Outdoors, vigorous plants in 50–100 L containers or in-ground beds can reach 600–1200 g per plant, weather permitting. Bud quality is maximized by meticulous late-flower humidity control and careful nutrient taper.
Nutrient taper and flush: Begin nutrient taper around day 49–56 of flower, depending on trichome maturity. Reduce EC by 20–30% and focus on balanced ratios rather than plain water in coco to avoid osmotic shock. The final 7–10 days can be run at EC 0.8–1.2 with adequate calcium and magnesium to prevent late senescence from spoiling resin quality.
Stress management: Temperatures above 28–29°C in late bloom can encourage foxtailing, particularly under high PPFD. Keep canopy temperatures stable and avoid large VPD swings across lights-off transitions. If using supplemental UV, limit to 0.5–1.5 kJ/m²/day during the last two weeks to avoid terpene burn.
Harvest, Drying, and Curing Protocol
Harvest timing is best guided by trichomes: target mostly cloudy with 5–15% amber for a bright, energetic profile. Waiting for 20%+ amber shifts toward a heavier body effect but risks terpene loss. Pistil color is less reliable; rely on magnified trichome assessment.
For drying, the 60/60 approach is a proven baseline: 60°F (15.5–16.5°C) and 60% RH for 10–14 days in darkness with gentle airflow. Aim for 0.3–0.5 m/s indirect air moving below and around, never directly at, the hanging flowers. Stems should snap with a fibrous crack before trimming and jarring.
Curing proceeds at 58–62% RH, with daily burps for the first 7–10 days, then weekly as aroma stabilizes. By day 21–30, citrus-haze notes typically peak; extended cures to 60–90 days add sandalwood and tea-like complexity. Keep jars cool and dark; light and heat are primary terpene degraders.
Post-harvest yield metrics commonly show 20–25% trim-to-flower mass retained after final manicuring on sativa spears. In practice, a 500 g/m² wet trimmed harvest may finish around 100–125 g/m² dry, depending on water content and structure. Resin heads from Amnesia Bilbo wash well, with ice water extracts delivering fragrant, lemon-forward hash.
