Auto Amnesia Platinum is an autoflowering take on the classic Amnesia archetype, bred by Bulk Seed Bank with a ruderalis, indica, and sativa heritage. The result is a plant that preserves the soaring, cerebral lift of Amnesia while delivering the speed and convenience of autoflower genetics. Growers choose it for its reliable seed-to-harvest window, vigorous growth, and heady effects that stay true to the Haze family.
In consumer circles, Amnesia varieties are known for high THC and minimal CBD, a profile Leafly summarizes as typically potent and uplifting with creative, euphoric qualities. Auto Amnesia Platinum reflects that reputation, but packages it in a compact, 10 to 13 week lifecycle from sprout to chop. This makes it appealing both to indoor hobbyists and outdoor growers seeking multiple runs per season.
Because it bears the Amnesia name, expectations often include citrus-forward terpenes and a bright, zesty bouquet. Many users associate Amnesia-type strains with daytime functionality and enhanced focus. Auto Amnesia Platinum aims to replicate those hallmark traits with the added efficiency of autoflowering habit.
In the broader market, autos have matured from novelty to serious performers, with modern lines frequently rivaling photoperiod potency. Bulk Seed Bank’s Platinum moniker signals a selected, stabilized expression emphasizing resin, aroma, and potency consistency. For growers and consumers alike, that consistency is the core value proposition of this cultivar.
Bred-By, Origins, and Market Context
Bulk Seed Bank bred Auto Amnesia Platinum, leveraging autoflowering ruderalis input to fix rapid flowering while curating a sativa-leaning profile rooted in Amnesia. The breeder’s aim appears to be a high-energy chemovar with shortened turnaround and dependable structure. This aligns with a decade-long trend where breeders refine autos for uniformity, potency, and yield.
Amnesia as a family holds a noteworthy place in modern cannabis culture, often linked to the Haze lineage and celebrated across Europe. Leafly profiles Amnesia as uplifting, creative, and euphoric with high THC, and that consumer feedback has anchored Amnesia’s identity in the market. Auto variants strive to maintain that identity while providing faster harvests.
The marketplace is saturated with Amnesia derivatives, including CBD-forward and autoflowering versions highlighted across informational resources and retail sitemaps. The CannaConnection sitemap lists numerous Amnesia autos and CBD crosses, underscoring the breadth of this family. Large retailers such as those indexed by SeedSupreme’s sitemap show the scale of demand for autos, reflecting their rapid rise among home growers.
Because breeders sometimes guard lineage as trade secrets, public genealogy can be opaque. SeedFinder’s Unknown Strain genealogy pages illustrate this broader industry tendency toward proprietary parentage. Within that context, Auto Amnesia Platinum’s exact parent clones may be undisclosed, but its expressed phenotype clearly aims at the classic Amnesia experience in an autoflower framework.
Genetic Lineage and Breeding Strategy
Auto Amnesia Platinum’s declared heritage is ruderalis, indica, and sativa, with the sativa fraction channeling the recognizable Amnesia headspace. The ruderalis input provides photoperiod independence, ensuring that flowering initiates by age rather than day length. The indica fraction likely contributes to internodal stability and resin density without dulling the energetic character.
Breeding autos often entails backcrossing to reinforce the target terpene and cannabinoid profile while keeping the autoflower trait dominant. Stabilization over multiple filial generations aims to tighten phenotype variation, which is key for consistent home grows. The Platinum designation suggests a selection focus on resin coverage and terpene intensity.
In the Amnesia ecosystem, many lines derive from Haze-type stock, sometimes with Skunk or other classics underpinning structure. While specific parental clones are not public, the sensory signatures of citrus, spice, and incense-like notes point to Haze-terpinolene-driven chemistry. The result is a cultivar that reads sativa in the nose and mind, but behaves like a well-behaved auto in the garden.
Modern autoflower breeding has narrowed the potency gap with photoperiods. Contemporary autos frequently test in the mid to high teens and into the low twenties for THC, depending on environment and phenotype. That trend positions Auto Amnesia Platinum on competitive footing for daytime enthusiasts.
Visual Traits and Morphology
Auto Amnesia Platinum typically grows medium in stature, often reaching 60 to 100 centimeters indoors under 18 to 20 hours of light. Internodes are moderately spaced, reflecting sativa influence, yet stems stay sturdy enough to carry dense flower sites. Expect a central cola dominant architecture with productive satellite branches when given adequate light distribution.
Leaf morphology leans toward a narrow to medium leaflet, with vigorous apical growth early, then rapid preflower stretch. Many autos exhibit a 1.5 to 2.0 times stretch from early flower to mid bloom, and this line commonly follows suit. In larger containers, plants may bulk out laterally, rewarding early low-stress training.
Mature flowers present lime to forest green calyxes, often dusted in silver trichomes that can push into a frosty, platinum-like sheen under strong lighting. Pistils range from cream to tangerine as they mature, offering visual cues for harvest timing. Bract stacks can be conical and relatively airy in true Haze fashion, yet dense enough to yield well when environment is dialed.
Resin production is a highlight in well-grown specimens, with sugar leaves collecting a sparkling coat by week six to eight of life. In optimized runs, you can expect pronounced bag appeal, thanks to bright coloration, pistil contrast, and trichome density. The overall morphology makes for easy trimming and efficient post-harvest processing.
Aroma and Flavor Spectrum
Amnesia-family aroma often skews toward zesty citrus, sweet lemon rind, and a light herbal spice, and Auto Amnesia Platinum follows that lead. Limonene and terpinolene-driven bouquets are common, delivering a fresh, top-note brightness. Underneath, you may find hints of cedar, basil, or anise, adding depth and complexity.
On the palate, expect a citrus-forward first impression, followed by a woody, herbal middle and a peppery-sweet finish. Vaporization at moderate temperatures can accentuate the sweet lemon aspect, while combustion sometimes brings out spice and incense. Users who enjoy Lemon Haze will recognize the energizing citrus character that, as Leafly notes for Lemon Haze, can feel euphoric yet grounded when dosed appropriately.
With a proper cure, aromatic intensity increases over weeks four to eight, as chlorophyll fades and terpenes meld. Jar burping preserves the volatile top notes, which are particularly important for Haze-style profiles. Avoid high-temperature drying that can strip terpinolene and limonene, both of which are sensitive to heat and airflow.
Cannabinoid Profile and Potency Expectations
Leafly characterizes Amnesia as commonly high in THC with low CBD, a pattern echoed in market lab data for Haze-forward chemovars. In autos, modern breeding regularly achieves THC in the mid to high teens and into the low twenties percent by dry weight. CBD is typically low, often at or below 1 percent, preserving a strongly psychoactive effect profile.
Actual potency depends on phenotype, environment, and post-harvest handling. Under optimized indoor LED lighting with a strong dry and cure, Auto Amnesia Platinum can approach the performance of photoperiod Amnesia-type lines. In suboptimal conditions, THC can fall several percentage points, and terpene content can halve compared to a dialed environment.
For practical planning, growers often budget for a THC window around 15 to 22 percent for quality autos of this class, with total terpene content around 1.5 to 3.5 percent. This placement is competitive with many market staples and keeps the cultivar in a stimulating, daytime-appropriate potency band. Compared for context, consumer favorites like GSC often exceed 20 percent THC, while Blue Dream is a long-standing benchmark for balanced potency and broad appeal.
If medical users require quantification, third-party lab testing of the harvest is the most accurate way to verify cannabinoid percentages. Small batch home test kits can offer a rough gauge, but professional analytics provide the precision needed for regimen planning. Store samples carefully before testing to prevent degradation and skewed results.
Terpene Profile and Chemical Drivers
The leading terpene in many Amnesia-style cuts is terpinolene, often accompanied by limonene, beta myrcene, and beta caryophyllene. Together, these compounds are associated with citrus, piney, and herbal top notes, plus woody spice and a faint incense. While exact percentages vary, terpinolene-rich samples commonly fall in the 0.2 to 0.8 percent range by dry weight, with total terpenes near 2 to 3 percent in well-grown flower.
Limonene contributes an uplifting citrus aroma correlated in survey research with mood elevation and perceived stress reduction. Beta caryophyllene interacts with CB2 receptors and can add a peppery kick, while myrcene can slightly soften the profile with herbal depth. Secondary terpenes such as ocimene, alpha pinene, and linalool may appear in trace to moderate amounts, rounding the bouquet.
Drying and curing strongly shape terpene retention. A slow dry near 60 percent relative humidity and cool temperatures often preserves volatile terpenes better than rapid dehydration. Light exposure also degrades terpenes, so dark storage during cure is recommended to protect both aroma and the perceived effectiveness.
Experiential Effects and Functional Use
Consumers commonly report that Amnesia-type strains are uplifting, creative, and euphoric, aligning with Leafly’s Amnesia overview. Auto Amnesia Platinum mirrors this profile, trending toward a clear, energetic onset and an expansive, mentally engaging plateau. The experience is often described as bright and outward-facing rather than introspective.
Functionally, this places the cultivar among daytime tools for brainstorming, socializing, and task engagement. Many users liken the tone to classic sativa icons such as Jack Herer, which Leafly notes as helpful for stress and appetite issues. The line also shares parallels with Lemon Haze’s euphoric uplift, though sensitive users should respect the potential for an anxious edge at high doses.
Dose titration matters with high-THC, low-CBD chemovars. Newer consumers often do best with one or two inhalations and a five to ten minute wait, especially with potent vaporization devices. Overconsumption can swing the experience toward raciness, so measured pacing maintains the targeted creative zone.
Potential Medical Applicability and Considerations
While controlled clinical data for a named cultivar is limited, the chemical profile points to common use cases. High-THC, terpinolene-limonene rich cultivars are frequently chosen by patients seeking mood elevation and daytime energy. Leafly’s Amnesia page emphasizes uplifting and creative qualities, which anecdotal reports link to relief in depressive or low-motivation states.
Jack Herer’s profile is often referenced for comparison, with Leafly noting utility in stress and lack of appetite. Users of Amnesia-type autos sometimes report improved appetite and mild nausea relief as well, consistent with THC’s known orexigenic potential. For some, caryophyllene’s CB2 activity is of interest for inflammatory contexts, though evidence remains preclinical.
Patients sensitive to THC may prefer microdosing strategies or a one-to-one pairing with CBD to reduce edginess. Because CBD content in this cultivar tends to be low, separate CBD supplementation may be necessary to achieve balance. As always, medical users should consult healthcare professionals, especially when combining cannabis with other medications.
Comprehensive Cultivation Guide: Seed to Harvest
Auto Amnesia Platinum is designed for efficiency, targeting a seed-to-harvest window of roughly 70 to 90 days under continuous lighting. Many growers see preflower by day 21 to 28, with the bulk of flowering from day 35 onward. Cooler environments and low light can add a week or more to the schedule, while optimal conditions keep it closer to 75 days.
Start seeds directly in the final container to avoid transplant stress, which can stunt autos due to their fixed lifecycle clock. A light, airy substrate with high porosity and moderate cation exchange capacity supports rapid root exploration. Coco blends or light potting mixes amended with perlite at 20 to 30 percent are common choices.
Provide 18 to 20 hours of light daily from sprout to finish. This maximizes photosynthetic activity without the diminishing returns sometimes seen above 20 hours. Outdoors, long summer days in higher latitudes can still produce excellent results thanks to autoflower independence from day length.
By day 35 to 45, shift nutrition toward bloom support while moderating nitrogen. Low-stress training during the first three weeks can open the canopy for more even bud development. Avoid high-stress topping after week three, as autos have limited recovery windows compared to photoperiod plants.
Environmental Parameters and Lighting
Aim for daytime temperatures of 24 to 28 Celsius and nighttime at 20 to 22 Celsius for most of the cycle. Relative humidity around 60 to 65 percent in early veg, tapering to 45 to 50 percent in late flower, supports healthy transpiration. A VPD range of roughly 0.8 to 1.2 kilopascals is a workable target for vigor and disease resistance.
Under LED lighting, target PPFD around 400 to 600 micromoles per square meter per second in early veg. Increase to 700 to 900 in early flower and 900 to 1,200 in late flower if CO2 is ambient and temperatures are controlled. These intensities can deliver a DLI near 35 to 45 mol per square meter per day in veg and 45 to 55 in flower under 18 to 20 hours of light.
Ensure balanced airflow with both oscillating fans and adequate extraction. Slight negative pressure helps keep odors contained and fresh air moving. Carbon filtration preserves discretion and prevents aroma bleed, which can become robust by mid bloom.
Nutrition, Irrigation, and Substrate Management
Feed lightly in the first 10 to 14 days, then ramp to full-strength vegetative nutrition by week three as preflower begins. Many growers find success at EC 1.2 to 1.6 in early to mid flower, tapering nitrogen while boosting phosphorus, potassium, calcium, and magnesium. In coco, maintain pH 5.8 to 6.2, and in soil or peat mixes, aim for pH 6.2 to 6.8.
Irrigate to 10 to 15 percent runoff to prevent salt buildup in soilless systems. In soil, water to full saturation and allow the top layer to dry between events to encourage gas exchange. Maintain root zone temperatures near 20 to 22 Celsius to support enzymatic activity and calcium uptake.
Supplemental calcium and magnesium are often beneficial under strong LED intensity due to higher transpiration demands. Silica can strengthen stems and improve stress tolerance in autos that pack on fast mass. Late flower PK boosters can be used judiciously, but avoid overfeeding that can cause harshness or delay senescence.
Training, Canopy Control, and Autoflower Specific Tactics
Autoflowers generally reward low-stress methods that preserve momentum. Begin gentle tie-downs by day 14 to 18 to flatten the canopy and expose lateral sites. Spiral or spoke-style LST can create an even set of tops without cutting the main stem.
Topping is situational. If vigor is high and the plant is ahead of schedule, a single top around the fourth node by day 18 to 21 can work, but many growers skip topping entirely with autos. Defoliation should be minimal and targeted, removing only large fans that cast shade on key bud sites.
Container size impacts architecture. For indoor autos, 3 to 5 gallon containers often balance root room and turnaround time. Air pruning containers can enhance lateral root development and prevent circling in fast veg conditions.
Integrated Pest and Disease Management
Fast-growing autos are resilient, but pests can still erode yield if unmanaged. Common issues include fungus gnats in wet substrates, spider mites in warm and dry rooms, and powdery mildew in stagnant, humid conditions. Establishing preventive IPM is more effective than reactive treatment.
Use sticky cards to monitor flying pests and adjust irrigation patterns to disrupt gnat life cycles. Beneficial insects like predatory mites or rove beetles can be deployed in living soil or organic setups. Neem alternatives such as botanical oils or microbe-based products can help in veg, but avoid heavy foliar sprays late in flower to protect flavor.
Environmental control is the backbone of disease prevention. Keep leaves in motion with fans, maintain appropriate VPD, and prune small interior shoots that will never reach light. Sanitize tools and surfaces between runs to reduce inoculum carryover.
Harvest Timing, Drying, and Curing Protocols
Harvest timing for this cultivar is best judged by trichome development rather than days on the calendar. Many growers target a mix of mostly cloudy heads with 5 to 15 percent amber for a balanced expression. Pistil coloration can guide, but trichomes tell the more reliable story.
Drying at around 60 to 62 percent relative humidity and 15 to 18 Celsius for 10 to 14 days preserves both terpenes and potency. Gentle airflow that does not blow directly on buds reduces uneven drying and terpene loss. Stems should snap rather than bend before moving to jars.
Curing proceeds in airtight containers at 60 to 62 percent humidity for four to eight weeks. Burp jars daily for the first week, then every few days as internal moisture equalizes. Target a final water activity near 0.55 to 0.62 to balance microbial safety and aroma retention.
Yield, Efficiency, and Performance Metrics
In dialed indoor conditions, Auto Amnesia Platinum can produce approximately 400 to 550 grams per square meter under strong LEDs and proper canopy management. Single plants in 3 to 5 gallon containers often land in the 60 to 150 gram range depending on phenotype, light intensity, and grower experience. Outdoors, long summer days can push per-plant yields higher when root volume and sunlight are ample.
Growers commonly assess efficiency via grams per watt, with autos averaging 0.6 to 1.2 g per watt under household-scale fixtures. Experienced cultivators with optimized environments sometimes exceed 1.5 g per watt with autos that respond well to training. Keep in mind that genetics, environment, and post-harvest practices jointly determine final quality and yield.
Uniformity is a strength in stabilized autos. Expect a tight height distribution and predictable harvest window, which eases space planning. The combination of speed and respectable yield makes two to three indoor runs per season feasible in the same space.
Post-Harvest Storage, Stability, and Lab Testing
THC and terpenes degrade when exposed to heat, oxygen, and light. Store cured flower in opaque, airtight containers at cool temperatures around 10 to 15 Celsius to slow oxidation. Avoid repeated warm-cold cycling that can condense moisture and disrupt water activity.
Under ideal storage, potency decline can be kept minimal over several months, while terpene brightness remains prominent. Over a year or longer, expect some conversion of THC to CBN and gradual aroma flattening. Vacuum sealing with humidity control packs can extend freshness, but do not compress delicate flower excessively.
For medical or data-driven users, consider periodic lab testing. Even a single certificate of analysis on a representative batch clarifies cannabinoid and terpene baselines. This enables more consistent dosing and more informed comparisons between grows or phenotypes.
Consumer and Grower Tips, Sourcing, and Final Thoughts
If you prefer a clear, creative daytime effect with citrus-forward aromatics, Auto Amnesia Platinum sits squarely in that niche. It is a natural pick for those who already enjoy Amnesia, Jack Herer, or Lemon Haze, as described by Leafly’s profiles, but want autoflower speed. Dose mindfully to avoid the edgy side of strong THC, especially if you are caffeine sensitive.
When sourcing seeds, look for reputable vendors that carry Bulk Seed Bank selections and provide fresh stock with high germination rates.
