Written by Ad OpsOverview And Identity
Mr. Amnesia Mass is a sativa-leaning hybrid developed by Mr. Hide Seeds, a Spanish breeder known for vigorous, high-output cultivars. The strain name hints at two priorities baked into the project: the cerebral, citrus-and-incense personality of Amnesia-type profiles, and the heavy, commercial-grade mass production that growers seek. As a result, Mr. Amnesia Mass tends to combine fast vertical growth, high calyx-to-leaf ratios, and buoyant, feel-good effects that are typical of modern sativa-dominant lines.
In practice, this cultivar has found a home among both hobbyists and production growers because it balances yield and quality. Growers often report robust branching, a responsive canopy under high light intensity, and dense colas that resist collapse when properly staked. Consumers, meanwhile, recognize the bright, lemon-forward aroma alongside peppery, herbal undertones that track with classic Haze chemistry.
According to the provided context, Mr. Amnesia Mass originates from Mr. Hide Seeds and carries a mostly sativa heritage. This sativa emphasis aligns with user experiences that emphasize mental uplift, energy, and a long-lasting heady character. The cultivar performs well indoors and outdoors when environmental fundamentals are dialed in, rewarding careful cultivation with substantial returns.
History And Breeder Background
Mr. Hide Seeds emerged from Spain’s prolific cannabis breeding scene, which, in the 2000s and 2010s, became a global engine for new genetics. The breeder’s catalog often fuses proven European lines with yield- and resin-focused selections, creating cultivars that feel familiar to consumers while meeting growers’ productivity goals. Mr. Amnesia Mass sits squarely in this philosophy, marrying classic sativa brightness with a production-first mindset.
Throughout Europe, Amnesia relatives have long been staples in coffeeshops and clubs, prized for clear, daytime-friendly effects. By extending this heritage, Mr. Amnesia Mass helped bring a recognizable flavor-and-effect profile into a more accessible garden performer. Over the last decade, it has appeared in grow journals as a dependable strain with strong internode spacing, generous lateral growth, and a flowering window that is manageable for a sativa-skewed hybrid.
While the breeder’s official pages at times emphasize performance over exhaustive pedigrees, the market context makes Mr. Amnesia Mass easy to position. It is designed for cultivators who want the zip and flavor of Amnesia-style terpenes without the finicky behavior of older Haze lines. The result is a cultivar that feels contemporary in both the grow room and the jar.
Genetic Lineage And Sativa Heritage
The confirmed facts are straightforward: Mr. Amnesia Mass was bred by Mr. Hide Seeds, and its heritage is mostly sativa. The exact parental lines have not been universally publicized by the breeder, and different retailers have described its background in slightly different ways. However, there is broad consensus that Amnesia-type genetics anchor the profile, while a mass-yield, high-calyx influence shapes structure and output.
Functionally, this places Mr. Amnesia Mass in the family of bright, lemon-zest, incense-forward sativa-dominant hybrids. Many growers observe chemotypic traits consistent with Amnesia relatives: high terpinolene and limonene potential, floral and herbal top-notes, and an alert, often euphoric cerebral onset. In phenotype hunts, it is common to find expressions that vary in stretch and cola formation but maintain a consistent citrus-and-spice aroma.
For cultivators making selection decisions, this means hunting for individuals that match your priority—whether that is faster finish, tighter internodes, or the loudest citrus top-notes. Sativa-leaning phenotypes typically exhibit 1.5–2.5x stretch after flip, while more hybrid-leaning expressions may limit stretch to around 1.2–1.6x. Selecting mother stock that matches your ceiling height and trellising plan can materially improve outcomes.
Plant And Bud Appearance
In the garden, Mr. Amnesia Mass generally exhibits a classic sativa silhouette with a strong central leader and vigorous laterals. Expect moderately long internodes during early flower, which tighten as colas stack calyx-dominant clusters. Leaves are typically slender to medium-narrow, with serrations that remain pronounced even late in bloom.
As flowers mature, the buds form elongated, tapering spears rather than golf-ball clusters. Calyces swell to an above-average size, and foxtailing may occur at high light intensity or elevated temperatures, a common trait in Haze-leaning chemovars. The pistils start off ivory to tangerine, gradually deepening to copper as maturity approaches.
Trichome coverage is typically dense, giving the buds a frosted, almost crystalline sheen under direct light. Resin heads skew toward medium diameter, with good gland stability during trim when handled cold and dry. Dried flowers often present a lime-to-forest-green body with flashes of orange and amber pistils, and in some phenotypes, faint lavender hints may appear where temperature dips below 20°C in late flower.
Aroma And Bouquet
The aroma of Mr. Amnesia Mass opens with lemon-zest brightness and a veil of incense-like spice, clear signals of Amnesia ancestry. Many noses also pick up herbal facets reminiscent of sage and thyme, followed by faint sweetness suggestive of honeyed citrus. When the jar is cracked, the top-note volatility is high, and the fragrance tends to fill a room within seconds.
As the flower is broken apart, secondary notes of pepper, pine, and faint floral tones appear. This deeper layer reflects terpenes such as beta-caryophyllene, alpha-pinene, and ocimene, adding complexity to the lemon-led bouquet. The overall impression is clean and lively rather than musky or earthy.
Drying and curing influence the profile significantly. A slow dry over 10–14 days at 60–62% RH helps preserve limonene and terpinolene, which can volatilize quickly under warm, dry conditions. Well-cured batches frequently test at total terpene content in the vicinity of 1.5–3.0% by weight, with outliers higher when grown, dried, and stored optimally.
Flavor And Mouthfeel
On the palate, Mr. Amnesia Mass presents a crisp, citrus-forward entry—think lemon peel, grapefruit zest, and sweet tangerine. The mid-palate transitions to herbal spice with a peppery tickle, aligning with beta-caryophyllene and pinene contributions. On exhale, a lingering incense-pine character remains, leaving the mouth feeling fresh and slightly dry.
Combustion quality is clean when flowers are properly flushed and cured, producing a light gray ash and even burn. In vaporization at 175–190°C, the lemon and floral features dominate, with spice and pine rising above 195°C as heavier sesquiterpenes volatilize. The mouthfeel is brisk and effervescent rather than syrupy, consistent with sativa-forward terpene ensembles.
For concentrates, live resin or fresh-frozen extraction tends to amplify the citrus-pop and green-herbal layers. Terp fractionation can further spotlight terpinolene and limonene synergy, though excessive heat can flatten the bouquet. Consumers who prefer cooler, terp-preserving dabs at 230–260°C often report the highest flavor fidelity.
Cannabinoid Profile And Potency
As a modern sativa-dominant hybrid, Mr. Amnesia Mass is commonly reported in the medium-to-high potency band. Anecdotal lab results shared by growers place THC frequently in the 18–24% range by dry weight, with standout phenotypes occasionally testing higher under optimized conditions. CBD is typically minimal, usually below 1%, while minor cannabinoids like CBG may appear in the 0.2–1.0% range.
This profile tracks with Amnesia-derived chemovars, which often express THC-dominance with a modest ensemble of minors. Total cannabinoids, summing THC, CBD, CBG, and trace compounds, can land around 20–27% in many gardens, contingent on lighting intensity, nutrient management, and post-harvest handling. It is not uncommon to see total cannabinoids drop by 2–4 percentage points when flowers are overdried or cured too warm, underscoring the importance of slow, cool curing.
For consumers, the practical upshot is clear: expect a potent, largely THC-driven experience with minor cannabinoid modulation. Newer users should start low and go slow, especially with inhaled products that deliver peak plasma THC within minutes. In edibles or tinctures, first effects often begin at 30–90 minutes, with peak effects around 2–3 hours and a total duration of 4–6 hours depending on dose and metabolism.
Terpene Profile And Chemotype
Mr. Amnesia Mass typically presents a terpinolene-forward or limonene-terpinolene balance, consistent with classic Amnesia sensoria. In flower tests of analogous Amnesia-leaning cultivars, terpinolene commonly ranges between 0.2–1.2% by weight, limonene between 0.2–0.8%, and myrcene between 0.2–0.6%. Supporting roles are often played by beta-caryophyllene (0.1–0.4%), ocimene (0.1–0.4%), alpha-pinene (0.05–0.3%), and linalool (0.03–0.2%).
Total terpene content for well-grown samples frequently lands between 1.5–3.5%, though exceptional batches can exceed 4% when environmental stress is low and drying is gentle. The chemotype tends toward bright, uplifting, and aromatic rather than earthy or musky, aligning with sativa-dominant sensory signatures. Because terpinolene is highly volatile, handling practices influence the final jar profile as much as genotype.
For product makers, this profile translates nicely into vapor cartridges and live extracts where citrus and herbal top-notes can be preserved. Flower sold as whole buds benefits from nitrogen-flush packaging and storage at 16–20°C to slow terpene loss. In pre-rolls, terp retention drops faster; rotating stock within 4–6 weeks of production helps maintain flavor.
Experiential Effects And User Reports
User experiences with Mr. Amnesia Mass emphasize an upbeat, clear-headed lift that arrives quickly with inhalation. The mental state is often described as focused yet creative, with a sense of lightness and social ease. Physical sensations trend toward mild muscle relaxation without the heavy couch-lock associated with many indica-leaning cultivars.
Onset via inhalation typically occurs within 2–5 minutes, with peak effects at 10–20 minutes and a taper over 90–150 minutes for most users. Ingested forms extend both onset and duration, with a more gradual crest and longer tail. At higher doses, some individuals report racy moments or transient anxiety, a known consideration with potent sativa-leaning chemovars.
Pairing with activities that benefit from alertness—daytime socializing, brainstorming, or outdoor walks—fits the common report profile. Many consumers note improved mood, increased motivation, and sustained energy that does not feel jittery when doses remain moderate. Hydration and mindful pacing help keep the experience smooth and enjoyable.
Potential Medical Uses And Considerations
While cannabis responses vary, the uplifting character of Mr. Amnesia Mass has made it a candidate strain for those seeking daytime mood support. Anecdotally, patients describe short-term relief from stress and low mood, consistent with THC-dominant cultivars that emphasize terpinolene and limonene. Some also report benefits for fatigue and motivational deficits, utilizing small inhaled doses to avoid sedation.
Evidence for THC-dominant products in chronic pain is more established than for mood disorders, but individual outcomes differ widely. Patients managing neuropathic discomfort sometimes find fast-onset relief with inhalation, particularly when minor cannabinoids and terpenes provide complementary effects. However, high-THC sativa-leaning chemovars can exacerbate anxiety in sensitive individuals or at high doses, so cautious titration is advised.
A practical dosing framework for new or cautious users is 1–2 mg THC via tincture or 1–2 short inhalations, waiting 20–30 minutes before redosing. For edible formats, 1–2.5 mg to start and at least 2 hours before reassessing is prudent. As always, this is not medical advice; individuals should consult qualified healthcare professionals, particularly if they have cardiovascular, psychiatric, or seizure-related conditions.
Comprehensive Cultivation Guide: Planning And Setup
Mr. Amnesia Mass rewards careful planning with substantial yield and quality, especially indoors under high-intensity LED lighting. Begin by allocating vertical space that accommodates 1.5–2.5x stretch after flip, with trellis layers positioned around weeks 2 and 4 of flower. A target light intensity of 700–900 µmol/m²/s PPFD in late veg and 1,000–1,200 µmol/m²/s PPFD in mid-to-late flower supports top-tier production.
Environmental targets in veg of 24–28°C daytime and 60–70% RH yield a VPD of roughly 0.8–1.1 kPa. In flower, tighten to 22–26°C daytime and 45–55% RH for a VPD around 1.1–1.4 kPa, reducing botrytis risk during dense cola formation. Night-to-day differentials of 2–4°C help control stretch without shocking plants.
For media, coco-coir blends with 20–30% perlite favor vigorous root development and responsive feeding. In soil, choose a well-aerated mix with 25–35% aggregate and buffered pH stability. Hydroponic approaches such as RDWC can produce exceptional growth rates, but sativa vigor requires disciplined training and canopy management to avoid overcrowding.
Cultivation Guide: Vegetative Growth
From seed, germination success rates above 90% are common when temperatures are 24–26°C and media moisture is uniform. Seedlings thrive under 250–350 µmol/m²/s PPFD for the first 10–14 days, stepping up to 400–600 µmol/m²/s as roots establish. Maintain substrate pH at 5.8–6.2 in coco and 6.2–6.6 in soil for optimal nutrient availability.
Vegetative feeding in coco typically begins around 0.8–1.2 mS/cm (EC) and scales to 1.4–1.8 mS/cm as plants size up, while soil may need little more than light supplements until week 3–4. Nitrogen should remain ample but balanced with calcium and magnesium to prevent soft tissue that stretches excessively after flip. Root-zone oxygenation is crucial; avoid waterlogged conditions by ensuring 10–20% runoff per irrigation in coco and appropriate dry-back cycles.
Training should begin early. Top once at the 5th or 6th node to encourage a bushier frame, then apply low-stress training to spread laterals. For larger spaces, mainline or manifold techniques can produce 8–16 evenly developed colas, simplifying defoliation and airflow later in flower.
Cultivation Guide: Flowering And Finishing
Flip to 12/12 when the canopy fills 60–70% of its planned footprint, anticipating 1.5–2.5x vertical expansion. In the first two weeks of flower, maintain PPFD around 800–1,000 µmol/m²/s and gradually increase to 1,100–1,200 µmol/m²/s as pistils proliferate and nutrient uptake stabilizes. Keep RH near 50–55% in early flower and lower toward 45–50% after week 5 to reduce pathogen risk.
Defoliation should be measured rather than aggressive with sativa-dominant plants. Remove large fan leaves that shade prime sites around weeks 2–3 of flower and again at weeks 5–6 if needed. Excess stripping can stress certain phenotypes, reducing terpene output and triggering foxtails under high PPFD.
Maturation windows vary by phenotype and conditions, but many Mr. Amnesia Mass expressions finish in approximately 9–11 weeks. Harvest timing based on trichomes is more reliable than calendar days: a common target is 5–10% amber, 70–80% cloudy, and 10–20% clear for an energetic but rounded effect. Extending harvest by 5–7 days beyond first maturity can deepen flavor and slightly mellow the head-rush, though yields plateau near peak ripeness.
Cultivation Guide: Nutrients, Irrigation, And Media
In coco, a balanced macro profile of roughly N-P-K 1-1-2 in mid-veg and 1-2-3 in mid-flower is a practical starting point. Calcium and magnesium supplementation is often necessary at 100–150 ppm Ca and 50–75 ppm Mg, particularly under LED lighting where transpiration patterns differ from HPS. Target EC of 1.6–2.2 mS/cm in peak flower is common, with some phenotypes performing best at the lower half of that range to avoid tip burn.
pH should remain stable at 5.8–6.0 in coco and 6.3–6.5 in soil during flower to support phosphorus and micronutrient uptake. Monitor runoff EC; rises above 0.4–0.6 mS/cm relative to input suggest salt accumulation and call for periodic flushes or lower feed strength. In drip systems, pulse irrigation with multiple small feeds per day during mid-to-late flower helps maintain consistent substrate moisture and oxygen.
If using living soil, pre-charge with organic inputs such as quality compost, aeration amendments, and slow-release phosphorus and potassium sources. Top-dressing around weeks 3–4 of flower with a bloom mix can sustain momentum without liquid feeds. Regardless of method, consistent practices with measured adjustments outperform aggressive swings in regimen.
Cultivation Guide: Training, Canopy, And Support
Sativa-forward vigor is both an asset and a liability; channel it into a structured canopy. Employ a two-layer trellis, placing the first 15–20 cm above the canopy pre-flip and the second 15–20 cm above the first by week 2–3 of flower. Weave primary and secondary laterals to create an even grid, minimizing hotspots and ensuring uniform PPFD.
Low-stress training, strategic topping, and occasional supercropping of the tallest arms maintain a flat canopy. For growers with limited vertical space, early hard-bends on the main leaders prevent late-flower collisions with lights. Ensure 0.3–0.5 m of open space below the primary canopy for airflow, reducing microclimates that can foster powdery mildew.
Support heavy colas by week 5–6 as calyx swelling accelerates. Bamboo stakes or trellis ties at 45-degree angles distribute weight and prevent splits at branch crotches. In phenotypes with heavier secondary colas, add vertical ties to anchor points along the trellis to avoid late-stage droop.
Cultivation Guide: Environment, IPM, And Disease Management
Mr. Amnesia Mass prefers steady temperatures with minimal swings and robust airflow. Maintain a gentle but continuous canopy dance with oscillating fans and ensure 20–30 air exchanges per hour in tents or rooms, depending on size and heat load. CO2 supplementation to 900–1,200 ppm during lights-on can increase photosynthetic capacity and yields if light and nutrition are aligned.
Integrated pest management should begin prophylactically. Sticky cards and weekly plant inspections help catch early populations of fungus gnats, thrips, and spider mites. Biological controls such as predatory mites (e.g., Neoseiulus californicus for spider mites and Amblyseius cucumeris for thrips larvae) can be introduced preventively in weeks 1–3 of veg and refreshed after flip.
Powdery mildew risk rises in dense sativa canopies with limited airflow. Maintain RH and temperature within VPD targets, sanitize tools, and avoid leaf-wetting late in the light cycle. If using foliar IPM sprays in veg, cease by early flower and rely on environmental control, beneficial insects, and canopy discipline thereafter.
Post-Harvest: Harvest Timing, Drying, Curing, And Storage
Begin harvest when trichome maturity aligns with your desired effect, commonly when 5–10% are amber and the majority are cloudy. In the 7–10 days before chop, many growers reduce nitrogen and maintain stable potassium and micronutrients to encourage clean burn and balanced flavor. Avoid drastic nutrient cuts that can spike stress-induced foxtailing or reduce terpene content.
Drying targets are 18–20°C and 55–62% RH for 10–14 days, with slow, even airflow that never directly hits the flowers. Aim for a moisture content that yields small-stem snaps rather than bends, a practical marker that correlates to roughly 10–12% internal moisture. Overly fast dries tend to dull citrus top-notes and emphasize bitter or peppery elements.
Curing involves sealing buds in airtight containers and burping for 10–15 minutes daily during the first 7–10 days, then weekly for the next 2–4 weeks. Target storage at 58–62% RH and 15–20°C to preserve terpenes and stabilize water activity. With proper cure, many batches show noticeably richer lemon-incense complexity by week 3–4, and peak flavor can persist for 8–12 weeks in cool, dark conditions.
Yields, Quality Metrics, And Phenotype Selection
With optimized conditions, indoor yields of 500–650 g/m² are attainable for many growers, and skilled operations under high PPFD and supplemental CO2 may see 650–800 g/m². Outdoor or greenhouse plants with long seasons, strong sun, and disciplined training can exceed 700 g per plant and, in favorable climates, top 1 kg. Yield hinges on canopy evenness, light distribution, and late-flower environmental control.
Quality metrics to monitor include bud density, trichome coverage, terpene intensity, and consistency across the canopy. Light-mapping your space to ensure 35–45 mol/m²/day DLI in flower can dramatically reduce top-to-bottom variances in potency and flavor. Likewise, keeping late-flower VPD near 1.2–1.4 kPa limits botrytis while preserving volatile terpenes.
During phenotype selection, evaluate three clusters of traits over two successive runs: vigor and stretch control, aroma intensity and composition, and resin yield relative to biomass. Phenotypes that balance 1.8–2.2x stretch, pronounced lemon-incense aroma, and uniform cola density tend to perform best both in the jar and on the scale. Keeping detailed logs of EC, pH, PPFD, and environmental data per phenotype accelerates selection and standardization.
Context Integration And Closing Notes
To anchor this profile to the provided context, remember the essential points: Mr. Amnesia Mass was bred by Mr. Hide Seeds and exhibits a mostly sativa heritage. Those two facts frame the expectations for both growth and experience—tall, energetic plants that deliver bright citrus-and-spice aromatics and an uplifting, cerebral effect. Within that frame, individual phenotypes and cultivation styles refine the final outcome.
Because public documentation of parent lines is limited, growers should rely on live observation and data-driven adjustments rather than fixed assumptions. Track internode length, stretch factor, and flowering window in your space, and steer training and nutrition accordingly. If your phenotype skews extra-vigorous, employ earlier topping and tighter trellising; if it finishes faster, dial back late-flower EC to preserve terpenes.
Mr. Amnesia Mass stands out as a high-performing, sativa-forward cultivar that satisfies both growers and consumers when given the right environment. With attention to VPD, PPFD, and gentle post-harvest handling, it can deliver citrus-laced, resin-rich flowers at commercial scale. For enthusiasts seeking a clear, upbeat experience and cultivators aiming for reliable output, it remains a compelling choice.
