Amnesia+ by D+Calidad Seeds: A Comprehensive Strain Guide

Amnesia+: Overview and Origin

Amnesia+ is a mostly sativa cannabis cultivar from D+Calidad Seeds, developed as a modern, high-clarity expression of the celebrated Amnesia family. The “plus” in its name telegraphs an emphasis on intensified aroma, resin production, and cerebral lift compared with classic cuts. While breeder-released lab figures are scarce in the public domain, Amnesia+ sits squarely in the high-THC, low-CBD tradition that defines Amnesia and Amnesia Haze.

Across Europe, Amnesia-leaning varieties have dominated coffee shop menus for two decades, with Amnesia Haze regularly ranking among top-selling sativas. Public sources consistently describe Amnesia-line effects as uplifting, creative, and talkative, with Amnesia Haze listed by Leafly as “giggly, euphoric, talkative” and characteristically high in THC with minimal CBD. Amnesia+ follows that lineage, offering veteran consumers a familiar, energetic profile that rewards daytime use when focus and sociability are desired.

The D+Calidad Seeds program appears to have targeted classic Haze-forward traits—long, speary flowers, citrus-incense aromatics, and a clean mental elevation. That focus typically implies a longer flowering window and a more vigorous stretch than average hybrids. Growers should anticipate a cultivar that responds best to training, moderate feeding, and a carefully managed climate to maximize quality and yield.

History and Breeding Background

Amnesia+ traces its heritage to the broader Amnesia family, which itself descends from the late-20th-century Haze gene pool combined with old-world Afghani and Skunk influences. Although exact parentage for Amnesia+ is not publicly documented, the breeding goal mirrors what made Amnesia and Amnesia Haze famous: a terpene-forward sativa with electric clarity and enduring popularity. European breeders historically refined these lines for coffee shop demand, prioritizing flavor, stable vigor, and an unmistakable cerebral spark.

Public strain references consistently position Amnesia and Amnesia Haze as high-THC, low-CBD cultivars capable of a vivid, social uplift. Leafly characterizes Amnesia Haze as a high-THC phenotype with “giggly, euphoric, talkative” effects, and Amnesia as uplifting and creative—consistent with the Haze family’s reputation. D+Calidad’s Amnesia+ can be read as a selection that preserves these effects while emphasizing ease of culture and dense resin.

The rise of Amnesia-type strains in Europe coincided with advances in indoor cultivation and the normalization of long-flowering sativas in controlled environments. Breeders and growers learned to tame tall sativa frames through training methods like SCROG and LST, allowing the nuanced terpene profile to shine. Amnesia+ arrives as a focused, modernized option for enthusiasts who love the classic but want refined vigor and a polished presentation.

Genetic Lineage and Comparison to Amnesia Family

While D+Calidad Seeds has not published a detailed pedigree for Amnesia+, its form and function align with Amnesia and Amnesia Haze standards. Historically, Amnesia Haze combines Haze ancestry with Afghani and Skunk lines, producing elongated colas, bright citrus incense aroma, and a clear, long-lasting lift. Amnesia+ exhibits the same sativa-forward growth habits and sensory cues, suggesting close kinship with those proven building blocks.

Amnesia Haze commonly tests above 20% THC in modern markets, with many seedbanks listing “very high” THC and CBD below 1%. That range serves as a realistic reference point for Amnesia+. Expect a dominant THC profile, trace CBD, and minor cannabinoids like CBG present in modest amounts.

Terpene-wise, Haze progeny frequently express terpinolene as a lead terpene, supported by myrcene, ocimene, caryophyllene, and limonene. This matrix yields citrus zest, herbal wood, and sweet spice—notes that Amnesia+ reliably presents. The result is a heady, sparkling signature that differentiates it from heavier, myrcene-dominant hybrids while maintaining enough base notes to feel rounded.

Appearance and Plant Morphology

Amnesia+ plants display unmistakably sativa architecture: rapid vertical growth, long internodal spacing, and strong apical dominance. In veg, expect a vigorous frame with narrow leaflets and a pronounced response to topping. Untrained, the plant can easily double or even triple in height during early flowering, a 1.5x–3x stretch characteristic of Haze-forward lines.

During bloom, flowers form in stacked, spear-shaped colas with an above-average calyx-to-leaf ratio. Buds lean medium in density—firmer than pure tropical sativas but airier than heavy indica Kush lines. The pistils run bright orange to deep tangerine as maturity approaches, contrasted against lime to forest-green calyces dusted in thick trichomes.

Under high-intensity lighting, Amnesia-line buds sometimes foxtail naturally, especially in late flower at high PPFD. While modest foxtailing is normal for Hazes, excessive heat or overlighting can accentuate the effect. Well-tuned environmental control preserves spear structure without sacrificing resin or aromatic complexity.

Trimmed flowers present as elongated, slightly feathered spears that showcase their sativa heritage. Sugar leaves tend to be small, making for efficient manicuring. When cured properly, the resin glistens while the calyxes retain a springy, resinous feel rather than rock-hard density.

Aroma and Flavor Profile

Amnesia+ speaks in classic Haze: zesty citrus, sweet herbs, and clean woodsy spice layered over an incense-like backbone. The top notes often evoke lemon zest and fresh-squeezed citrus, with subtle hints of lime rind. Mid-tones add sweet basil, anise, and pine-leaning terpinolene brightness.

On the tongue, initial flavors are lemon-peel sharp with a sweet, slightly floral lift. As the vapor warms, sandalwood, cedar, and peppery accents appear, suggesting caryophyllene and humulene support beneath the citrus. The finish lingers as lemon-herbal candy with a faint earthy-musky echo typical of myrcene.

The overall intensity is high but surprisingly clean, cutting through the palate without the heavy, cloying sweetness found in dessert hybrids. Proper curing at 58–62% relative humidity preserves citrus top notes, which can volatilize quickly if overdried. Connoisseurs often note that the second and third pulls reveal the most nuanced spice and wood.

Cannabinoid Profile: Expected Ranges and Lab-Driven Benchmarks

Direct, large-sample lab datasets for Amnesia+ remain limited in public channels, but closely related Amnesia lines provide practical benchmarks. Amnesia Haze is widely reported as high THC and low CBD, with many market samples testing in the 20–26% THC range and <1% CBD. Seedbank summaries for Amnesia Haze frequently label THC as “very high” (over 20%) and CBD in the 0–1% band.

It is therefore reasonable to expect Amnesia+ to express THC in the high-teens to mid-20s under competent cultivation, with CBD typically below 1%. CBG in Amnesia-type samples commonly appears around 0.3–1.0%, though values vary by phenotype and maturity. THCV can be detectable in some sativa-leaning cultivars; if present in Amnesia+, it would likely be trace to low (for example, <0.5%).

Total cannabinoids in well-grown Haze-derived flowers frequently surpass 20–25% when THC dominates the profile. Total terpene content often falls in the 1.0–3.0% range by dry weight, influencing perceived potency and effect onset. As always, individual lab outcomes depend on genotype, environment, harvest timing, and post-harvest practices.

Terpene Profile: Dominant Compounds and Sensory Correlates

Haze-family chemistry often centers on terpinolene as the dominant terpene, supported by myrcene, ocimene, limonene, caryophyllene, and humulene. This composition helps explain the uplifted, sparkling effect many consumers describe with Amnesia+. Leafly’s coverage of Haze-family terpenes highlights terpinolene’s role in producing energizing, clear-headed experiences in cultivars like Super Lemon Haze and Amnesia Haze.

In practical terms, expect terpinolene to contribute piney-floral citrus, ocimene to add sweet-herbal lift, and limonene to amplify lemon-zest brightness. Myrcene typically provides a faint earthy-musky foundation without pulling the profile into sedative territory. Caryophyllene and humulene add peppered wood and subtle bitterness, rounding the nose and supporting a lingering finish.

Typical ranges seen in Haze-line flowers include terpinolene at roughly 0.3–1.5% of dry weight, with the total terpene fraction spanning 1.0–3.0%. Myrcene and ocimene often sit around 0.1–0.6% each, while limonene may register 0.1–0.5%. These ranges are indicative, not prescriptive; actual outputs hinge on phenotype, cultivation inputs, and post-harvest care.

Experiential Effects and Use Cases

Amnesia+ is built for clarity, creativity, and social momentum. Consumers familiar with Amnesia Haze and Amnesia report giggly, euphoric, and talkative effects that shine in daytime contexts. Many describe a rapid onset within minutes, peaking at 30–45 minutes and gradually tapering over 2–3 hours depending on dose and individual tolerance.

The headspace is typically bright and outward-facing, making Amnesia+ a candidate for brainstorming, collaboration, or outdoor activities. Audio-visual appreciation often feels enhanced, with music and color perceived as especially vivid. Unlike heavy indica-dominant strains, Amnesia+ usually avoids couchlock, though overconsumption can feel racy.

Common side effects mirror what Leafly users report for Amnesia Haze: dry mouth, occasional dizziness, and in susceptible individuals, a tendency toward anxiety or paranoia at higher doses. New or anxious consumers should start low, especially with high-THC batches. Hydration and pacing generally mitigate the minor discomforts.

Experienced users often deploy Amnesia+ as a mood shifter on sluggish mornings or during creative blocks. Its sociable nature also suits small gatherings and conversations, where it can catalyze laughter and flow. For late-night use, some may find the mental tempo too lively, preferring to reserve the cultivar for daylight or early evening.

Potential Medical Applications (Non-Clinical, Evidence-Informed)

While formal clinical trials on Amnesia+ are not available, its family profile suggests targeted, situational benefits. Uplifted mood and enhanced motivation can be useful for low-mood states or mild fatigue, echoing user reports for Amnesia-line strains. The clear, non-sedating headspace may help some patients with attention-demanding tasks, though outcomes vary widely by individual and dose.

High-THC, low-CBD chemotypes can provide analgesic support for certain pain types, but may be less effective for deep inflammatory pain compared to balanced THC:CBD options. Evidence from nabiximols studies suggests cannabinoids can aid neuropathic pain and spasticity, though formulations and dosing differ from smoked or vaporized flower. Patients sensitive to THC-related anxiety should approach cautiously and consider microdosing strategies.

For mood and stress, Amnesia-type strains are frequently reported by users as uplifting and euphoric. However, paradoxical effects—such as increased heart rate or anxious ideation—occur in a minority of consumers, particularly at higher doses. As with any cannabis use for health, consult a clinician where possible, dose gradually, and track responses.

Practically, many medical users reserve Amnesia+ for daytime relief of low energy or situational low mood, employing smaller doses to avoid overstimulation. Vaporization offers finer control and a cleaner terpene expression, which some patients prefer. For insomnia or nighttime anxiety, a more sedating chemotype is usually a better match than a Haze-forward sativa.

Comprehensive Cultivation Guide: Indoors (Environment, Training, and Scheduling)

Amnesia+ thrives indoors when its sativa vigor is guided from the start. Veg under 18/6 for 3–5 weeks, topping early and often to break apical dominance. Low-stress training (LST) and Screen of Green (SCROG) are strongly recommended to convert vertical energy into a wide, even canopy.

Expect a 1.5x–3x stretch during the first 2–3 weeks of 12/12, so set your trellis before flip and hold tops 15–30 cm below the light’s ideal zone. This cultivar tolerates robust photon flux once established, but Hazes can foxtail under sustained excess; target 700–900 µmol/m²/s in early bloom, rising to 900–1,100 µmol/m²/s in mid-to-late bloom if CO2 is 1,000–1,200 ppm. Without CO2, aim closer to 700–900 µmol/m²/s to reduce stress.

Temperature sweet spots run 24–28°C by day and 18–22°C by night in flower. Manage VPD near 1.2–1.5 kPa in mid-bloom, tapering humidity from ~55% down to ~45% by late bloom to limit botrytis risk on spear colas. Strong horizontal airflow and frequent canopy pruning are essential due to the long, stacked flower structure.

Feeding should be moderate for a sativa: many growers succeed at 1.2–1.8 EC (600–900 ppm 500-scale) in coco/hydro and 0.8–1.4 EC in living soils with top-dressing support. Anecdotal reports from Amnesia Haze growers note sensitivity to overfeeding and light burn, as well as the need to tie down multiple limbs—Amnesia+ behaves similarly. Keep root-zone pH at 5.8–6.2 in coco/hydro and 6.3–6.8 in soil to optimize nutrient uptake.

Comprehensive Cultivation Guide: Outdoors and Greenhouses

Outdoors, Amnesia+ excels in warm, Mediterranean-like climates with long, dry autumns. In temperate zones, greenhouses extend the season and protect against October rains, which can threaten large, spear-shaped colas. Flowering typically completes in 10–12 weeks from flip; outdoors in the Northern Hemisphere, plan for late October to early November harvests.

Plant early to maximize root mass, and use large containers or in-ground beds with rich, well-aerated soil. Sativas respond well to living soil systems with ample microbial life, covering 40–60 L containers at minimum or, ideally, raised beds. Mulching and drip irrigation stabilize moisture and reduce fluctuations that can trigger foxtailing or nutrient swings.

Sun-grown Amnesia+ can become very tall—2–3 meters is not unusual with a long vegetative period. Continuous topping and LST keep the canopy manageable and increase light penetration. Netting or bamboo support is prudent to prevent wind damage to lengthy colas.

Humidity management is the primary challenge late in the season, especially in coastal or humid regions. Thin interior growth and remove lower, shaded nodes after stretch to improve airflow by 20–40%. Sulfur evaporators or biological controls in greenhouses can preempt powdery mildew, a risk for dense, late-flowers in shoulder seasons.

Nutrition, Irrigation, IPM, and Stress Management

Amnesia+ prefers steady, moderate nutrition rather than aggressive feeding. In coco, begin around 1.2 EC in veg and rise to 1.6–1.8 EC in peak bloom, watching leaf tips for burn. In organic systems, target a balanced NPK with added calcium, magnesium, and trace minerals; frequent light top-dresses outperform occasional heavy amendments.

Irrigation volumes should achieve 10–20% runoff in inert media to prevent salt accumulation. Watering frequency depends on pot size and environment, but consistent, smaller irrigations stabilize EC and reduce root stress. Maintain dissolved oxygen with good drainage and avoid prolonged saturation that can invite Pythium.

Integrated Pest Management (IPM) is essential for a longer-bloom sativa. Implement weekly scouting, sticky traps, and prophylactic beneficials (e.g., Amblyseius cucumeris for thrips, Phytoseiulus persimilis for spider mites) early in veg. Neem-alternative botanical oils or microbial products (e.g., Bacillus subtilis, Beauveria bassiana) can be rotated in veg; discontinue foliar sprays once buds set to protect flavor and safety.

Stress management pays dividends with Hazes. Keep da
