Amnesia Haze Ultra CBD is a modern CBD-forward reinterpretation of a celebrated sativa classic. Bred by Élite Seeds, a Spanish breeder known for ratio-defined CBD lines, the cultivar was designed to retain the soaring clarity of Amnesia Haze while smoothing edges with cannabidiol. The result aims to deliver the hallmark citrus-haze character with more predictable, user-friendly psychoactivity.
The development of CBD-rich variants accelerated after 2013 as testing labs and breeders increasingly selected for balanced chemotypes. Élite Seeds was among the European companies to systematize breeding for quantifiable THC:CBD ratios, frequently targeting 1:1 and 1:2 outcomes. Amnesia Haze Ultra CBD reflects that movement, blending a storied flavor lineage with data-driven cannabinoid targets.
According to community-sourced databases like SeedFinder, Amnesia Haze Ultra CBD traces to Amnesia Haze (Soma Seeds) crossed with a CBD-rich donor. This is consistent with Élite Seeds’ approach of pairing elite THC cultivars with proven CBD parents to reach stable ratios. It anchors the cultivar in a well-documented haze tradition while aligning with contemporary wellness-focused profiles.
The name Ultra signals a purposeful enhancement rather than a simple remake. In practice, growers and consumers tend to notice that the CBD element moderates intensity without erasing the sparkling headspace Amnesia lines are known for. The cultivar occupies a middle path between recreational brightness and calm functionality, reflecting its breeding intent.
Genetic Lineage and Breeding Rationale
The backbone of this hybrid is Amnesia Haze from Soma Seeds, a mostly sativa selection with Southeast Asian and Hawaiian influences. Typical Amnesia Haze parents express terpinolene-forward aroma, long internodes, and a 10 to 12 week bloom window. By pairing it with a CBD-dominant donor, Élite Seeds sought to produce a chemotype with elevated cannabidiol and moderated delta-9 THC.
SeedFinder’s lineage note lists the cross as Amnesia Haze (Soma Seeds) x CBD strain, which aligns with the product’s positioning as a balanced sativa. While some database pages also display navigational genealogies such as Original Strains’ Unknown Strain or Grow Today Genetics entries, those are separate items in the site’s taxonomy rather than direct contributors here. The working understanding remains a classic haze mother with a CBD-rich pollen source.
From a breeding strategy standpoint, pairing a THC-dominant sativa with a CBD donor often produces varied chemotype segregation in seed lots. Breeders stabilize this by recurrent selection and by using parents that are homozygous or highly consistent for cannabinoid synthase genes. With enough selection pressure and testing, a majority of offspring cluster around the targeted 1:1 to 1:2 THC:CBD ratio.
The sativa heritage is preserved through morphology and terpene expression, particularly citrus, pine, and incense notes often associated with Amnesia lines. The CBD parent contributes not just cannabidiol but often a shift in minor terpenes, adding bisabolol or humulene to the bouquet. Together, the cross aims to deliver a more versatile daytime profile without sacrificing vivid haze character.
Morphology and Visual Traits
Amnesia Haze Ultra CBD presents as a mostly sativa plant with medium-tall stature and strong apical dominance. Expect rapid vertical growth in early flower, with a typical stretch of 1.6 to 2.2 times the pre-flip height. Nodes are moderately spaced, allowing good airflow when trained with topping and low-stress techniques.
The leaves are long and serrated with a lighter lime-green color under high photosynthetic flux, deepening under moderate light. Buds form as elongated spears with foxtail tips in high-heat or high-PPFD conditions, a familiar trait in haze-heavy backgrounds. When dialed in, calyx stacking is elegant and resinated, with a thin but bright layer of trichomes frosting the outer bracts.
Mature colas carry a vibrant mix of orange to saffron pistils against pale greens and occasional lavender hues in cooler nights. The CBD influence often increases bud density slightly compared with classic Amnesia Haze, improving trim yield and bag appeal. Sugar leaves are modestly sized, making hand trimming manageable and preserving a high bract-to-leaf ratio.
Roots are vigorous in both coco and hydroponic systems, responding well to ample oxygenation and stable EC. Stems remain flexible yet strong, which suits trellising and screen-of-green setups. Overall, it is a plant that rewards canopy management and a stable environment with excellent architecture and cleanliness.
Aroma and Terpene Expression
On first rub, the nose delivers a burst of lemon zest and sweet citrus peel, quickly followed by peppered pine and green mango. A second pass reveals classic incense and cedar notes that haze aficionados will recognize immediately. Beneath that, there is a soft floral-powder layer that hints at bisabolol or linalool contributions from the CBD side.
When flowers cure for four to six weeks, the terpene clarity sharpens and the citrus becomes more candied, like preserved lemon with herbal tea. Terpinolene-driven bouquets can present as apple skin and pine with effervescent top notes. Caryophyllene and humulene provide an undercurrent of spice and faint earth, balancing the high-toned aromatics.
Terpene intensity is typically medium to high, with total terpene content often clustering between 1.5 and 3.0 percent of dry weight in well-grown material. In dialed-in environments and optimally cured batches, totals near 3.5 to 4.0 percent are achievable, though less common. These levels translate to a room-filling aroma when jars are opened and a persistent scent in grind.
Flavor and Mouthfeel
The inhale leans bright and zesty, with lemon-lime, sweet orange, and a sprig of lemongrass as primary notes. A resinous pine quality rides along, offering structure that keeps the citrus from becoming cloying. Subtle herbal tones reminiscent of sage and green tea appear on slower draws.
On the exhale, expect a peppery snap with a smooth, slightly creamy finish that suggests bisabolol and small amounts of linalool. Product grown and cured at lower temperatures often retains a refreshing, almost menthol-adjacent lift without actual mint. In joints and vaporizers, the flavor stays consistent for multiple pulls before drifting into dry spice and cedar.
Mouthfeel is clean and medium-bodied, with relatively low harshness when properly flushed and cured. Vaporization at 175 to 190 Celsius emphasizes citrus and floral components, while higher temperatures bring out spice and wood. Concentrates pressed as rosin typically express the citrus-pine axis strongly, translating well to both cold and warm dabs.
Cannabinoid Profile and Ratios
As a CBD-forward haze hybrid, Amnesia Haze Ultra CBD is commonly selected to express balanced to CBD-dominant ratios. In contemporary lab results for similar Élite Seeds lines, growers often see THC in the 6 to 12 percent range and CBD in the 8 to 16 percent range by dry weight. This positions many phenotypes near a 1:1 to 1:1.5 THC:CBD ratio, with some leaning toward 1:2 in CBD-heavy selections.
Total cannabinoids typically land between 14 and 22 percent, reflecting the moderated THC ceiling and the elevated CBD floor. Ratios matter as much as absolute potency here; a 10 percent THC and 12 percent CBD flower can feel distinctly different from a 16 percent THC and 2 percent CBD sativa. In practice, the balanced versions provide a clearer headspace and gentler rise.
Method of consumption influences perceived potency; inhaled routes act within minutes with a 2 to 3 hour duration, while edibles act over 4 to 8 hours with more body heaviness. CBD has been shown to modulate some THC-evoked effects via multiple mechanisms, including 5-HT1A receptor activity and allosteric modulation at CB1. That modulation does not eliminate psychoactivity but can blunt anxiety and tachycardia in a subset of users.
Because seed-grown CBD hybrids may segregate, testing is prudent if consistent outcomes are required. Quick thin-layer chromatography kits and portable immunoassays can estimate ratios from small samples, while HPLC provides definitive numbers. Selecting mother plants after lab verification is the most reliable way to lock in the desired chemotype.
Terpene Profile and Minor Aromatics
The dominant terpene in most Amnesia-derived cuts is terpinolene, frequently measuring 0.4 to 1.0 percent of dry flower when total terpenes sit near 2 to 3 percent. Beta-myrcene commonly follows at 0.2 to 0.8 percent, lending sweet mango and grounding body. Beta-caryophyllene often appears at 0.2 to 0.6 percent, contributing peppery spice and interacting with CB2 receptors.
Limonene usually presents between 0.1 and 0.4 percent in this cultivar’s brighter phenotypes, sharpening the citrus top notes. Ocimene may be detectable in the 0.05 to 0.3 percent range, providing green, slightly sweet aromatics that amplify the terpinolene pine. Humulene and linalool often round out the stack at trace to moderate levels, adding woody dryness and floral calm.
Minor compounds like nerolidol and bisabolol can be more prominent in CBD crosses than in pure THC haze lines. These contribute to perceived smoothness and a tea-like sweetness in the finish. Total terpene content is strongly correlated with cultivation environment and curing practices, so achieving the upper end demands careful post-harvest handling.
Experiential Effects and Functional Use
Most users describe an uplift that is bright and lucid rather than racy, reflecting the moderating influence of CBD. The onset with inhalation is typically felt within 5 to 10 minutes, peaking around 30 to 45 minutes. Headspace tends to be focused and conversational with enhanced sensory acuity and mild euphoria.
Body effects begin as a gentle loosening of the shoulders and neck with low to moderate muscle relaxation. The absence of heavy sedation makes it suitable for creative work, outdoor activities, and social settings. Appetite stimulation is present but not overpowering compared with heavier indica-dominant cultivars.
Compared with standard Amnesia Haze, this CBD-forward version often produces fewer reports of THC-induced anxiety or palpitations, especially in sensitive individuals. That said, set and setting remain important, and overconsumption can still produce unease. Many users find that smaller, more frequent doses maintain clarity and functionality over multi-hour windows.
In edibles or tinctures, the profile emphasizes steady mood elevation and body calm over a long arc. Microdosing at 1 to 2.5 milligrams THC paired with 2 to 5 milligrams CBD is a common protocol for daytime tasks. For inhalation, a few small puffs spaced by several minutes allow titration to effect with minimal overshoot.
Potential Medical Uses and Research Notes
CBD-rich cannabis has been studied for anxiety, pain, inflammation, and seizure reduction, among other indications. Clinical data show that CBD can reduce seizure frequency in some pediatric epilepsies; for example, purified cannabidiol led to median seizure reductions around one third in randomized trials for Dravet syndrome. While Amnesia Haze Ultra CBD is not a pharmaceutical product, its cannabinoid balance mirrors profiles explored for anxiolytic and antinociceptive potential.
Users frequently report relief for tension headaches, mild neuropathic discomfort, and stress-related somatic tightness. The sativa-leaning terpenes may contribute to a brighter mood lift, which can be supportive for situational anxiety or low motivation. Beta-caryophyllene’s CB2 activity has been investigated for anti-inflammatory effects, complementing CBD’s broader mechanisms.
For daytime anxiety, many patients prefer balanced THC:CBD ratios that preserve cognitive flexibility without strong intoxication. Observational cohorts have noted improved anxiety scores with CBD-rich cannabis, though placebo effects and dosing variability remain confounders. A consistent batch and a known ratio improve repeatability when used adjunctively under medical guidance.
As with any cannabis regimen, individual responses vary and interactions with medications are possible, particularly those metabolized by CYP450 enzymes. People with cardiovascular concerns, a history of psychosis, or those who are pregnant should consult clinicians before use.

Comprehensive Cultivation Guide: Environment and Scheduling
Amnesia Haze Ultra CBD thrives in stable, moderately warm environments with excellent airflow. Ideal daytime temperatures land between 24 and 28 Celsius during flower and 22 to 27 Celsius in veg, with nighttime drops of 3 to 5 degrees. Relative humidity is best kept around 60 to 65 percent in late veg, 50 to 55 percent in early flower, and 45 to 50 percent in late flower.
Target vapor pressure deficit between 0.8 and 1.2 kPa in veg, rising to 1.0 to 1.4 kPa in flower to mitigate botrytis risk in the elongated colas. As a mostly sativa plant, it tolerates higher light intensities if fed and irrigated properly, but excessive PPFD in heat can provoke foxtailing. Aim for 600 to 800 µmol m−2 s−1 PPFD in flower, with advanced growers pushing up to 900 if CO2 supplementation and cooling are in place.
Vegetative photoperiods of 18/6 or 20/4 work well, with 3 to 5 weeks of veg sufficient for a filled screen in a scrog. Expect a stretch of 1.6 to 2.2x after switching to 12/12, and plan trellis positioning ahead of the flip. Flowering time commonly ranges from 65 to 75 days, shaving roughly a week from some traditional Amnesia Haze cuts due to the CBD cross.
Outdoor and greenhouse schedules should consider the long bloom period relative to autumn rains. In Mediterranean climates, harvests typically fall from early to mid October. In shorter-season regions, greenhouse light dep or early planting is recommended to avoid late-season moisture spikes that can threaten large sativa colas.
Cultivation Guide: Nutrition, Irrigation, and Media
In coco or hydro, maintain root zone pH at 5.7 to 6.0 in veg and 5.8 to 6.1 in flower. In peat or soil mixes, a pH of 6.2 to 6.6 supports balanced nutrient uptake for this chemistry. Electrical conductivity targets of 1.2 to 1.6 mS cm−1 in veg and 1.6 to 2.2 mS cm−1 in mid flower suit most phenotypes.
Calcium and magnesium supplementation is beneficial under high-intensity LED lighting. Provide 100 to 150 ppm Ca and 40 to 60 ppm Mg through veg and early flower, tapering late to avoid leaf burn. Phosphorus and potassium should rise from week three of flower onward, with many growers increasing K by 20 to 30 percent during weeks five to seven to support calyx development.
Automated drip irrigation with frequent small pulses works well in coco at 20 to 35 percent runoff per day. In soil, allow the top inch to dry between waterings while keeping the lower horizon evenly moist. Oxygenation is crucial; perlite or pumice at 20 to 30 percent significantly increases root vitality in peat-based blends.
Organic programs built on living soil excel if nitrogen is moderated after the second week of flower. Top-dressings of high-quality compost, kelp, and a bloom amendment containing soft rock phosphate, sulfate of potash, and trace minerals keep the plant balanced. Avoid overfeeding late since CBD-forward sativas can hold residual nitrates that dull flavor and harshen smoke.
Cultivation Guide: Training, Canopy, and Plant Health
Topping at the fifth node produces a manageable bush that responds beautifully to low-stress training and screen-of-green. Deploy a trellis with 5 to 7 centimeter mesh and weave leaders horizontally to create an even canopy. This evens light distribution and curbs sativa stretch without resorting to high-stress techniques that can stall growth.
Defoliate lightly in weeks two and three of flower to open the interior and reduce humidity pockets. Lollipopping the lower 20 to 30 percent of the plant focuses energy into the upper flowering sites. Avoid aggressive defoliation late in bloom, as it can disrupt transpiration balance in this cut.
Integrated pest management should start in veg with beneficial predators like Neoseiulus californicus and Amblyseius swirskii for mite prevention. Sticky cards and weekly scouting catch early thrip or fungus gnat populations before they escalate. Powdery mildew and botrytis can be mitigated by good airflow, sulfur vaporization in veg only, and strict humidity control in late flower.
Silica supplements at 50 to 100 ppm strengthen cell walls and reduce lodging in tall canopies. If running CO2 between 800 and 1200 ppm, ensure adequate calcium supply and keep leaf surface temperatures in check with strong, laminar airflow. Healthy, turgid leaves with slightly raised petioles are a reliable sign of correct environment for this cultivar.
Harvest, Yield, and Post-Harvest Handling
Indoor yields typically range from 450 to 600 grams per square meter under 600 to 800 µmol m−2 s−1 lighting when scrogged. In greenhouses with long-season management, individual plants can reach 800 grams to 1.5 kilograms with multi-top training. Outdoor plants in full sun and well-amended soil commonly produce 400 to 800 grams per plant, depending on season length and root volume.
Trichome monitoring is key, but CBD-rich cultivars do not always follow the amber-percentage heuristics of THC-dominant lines. Many growers harvest when trichomes are mostly cloudy with 5 to 10 percent amber to preserve a brighter effect, usually around day 68 to 72. If a heavier body feel is desired, extending to 10 to 15 percent amber can deepen the effect but may dull the citrus top notes.
A slow dry at 18 to 20 Celsius and 55 to 60 percent relative humidity for 10 to 14 days preserves terpenes and curbs chlorophyll bite. Cure in airtight containers with daily burps at 62 percent target water activity during the first two weeks, moving to weekly burps thereafter. Full flavor maturity usually arrives between week four and week eight of cure, with terpene integration and a smoother burn.
For rosin, expect press yields of 15 to 22 percent from high-grade flower and 30 to 60 percent from premium bubble hash, reflecting trichome maturity. Lower press temperatures, such as 88 to 96 Celsius, retain citrus terpenes without sacrificing too much output. Keep post-press storage cool and dark to minimize terpene oxidation and CBD isomerization over time.
Phenotype Selection, Stability, and Testing
Seed-grown CBD hybrids can display chemotype segregation, especially in early filial generations. In general breeding contexts, crosses between THC-dominant and CBD-dominant parents can yield distributions approximating THC-dominant, balanced, and CBD-dominant phenotypes. Élite Seeds focuses on stabilizing ratios, but growers seeking uniformity should still phenohunt and test.
Select for plants that finish within the 65 to 75 day window, carry strong citrus-pine aroma, and feature moderately dense spears without excessive foxtailing. Discard phenotypes with weak lateral branching or extreme internodal stretch that resists containment. Prioritize resin coverage and a terpene profile that remains pronounced after a two-week cure.
Use inexpensive cannabinoid test kits to screen early, then confirm winners via HPLC for accurate THC:CBD ratios. Maintain mother plants from tissue culture or clean-cut procedures to prevent pathogen buildup over successive cycles. Record-keeping of feed, environment, and sensory notes across runs will tighten consistency and reduce drift.
If a 1:1 target is the goal, cluster selection around phenotypes that repeatedly test within 0.8:1 to 1.2:1 THC:CBD. If a CBD-leaning effect is preferred, seek 1:1.5 to 1:2 outcomes and pair with terpene-rich profiles for perceived potency. Over time, clonal propagation of the chosen keeper secures both the chemical and sensory signature.
Appearance Summary for Consumers
Buds are elongated and tapering, often described as spears rather than golf balls. Calyxes stack neatly with a silver dusting of trichomes that reads as a frosty sheen rather than heavy granulation. Pistils shift from peach to deep orange as maturity sets in.
The bag appeal is bright and inviting, with lime-green hues and occasional violet flecks in cooler rooms. Break-apart structure is medium-tight, not overly airy despite the sativa lean. Grinding releases a strong citrus-pine perfume that signals the terpinolene-caryophyllene core.
Context and Source Notes
This cultivar is attributed to Élite Seeds and is mostly sativa by heritage, aligning with breeder communications and community catalogs. SeedFinder’s entry lists the pedigree as Amnesia Haze from Soma Seeds crossed with a CBD strain, which matches the flavor and ratio behavior reported by growers. The same database includes navigational items that mention Original Strains’ Unknown Strain and Grow Today Genetics’ Goku Ssj4, but those are separate genealogical pages and not direct parents of this cultivar.
Community grow logs, lab testing across similar CBD haze lines, and breeder materials inform the ranges cited here. For example, total terpene contents of 1.5 to 3.0 percent and THC:CBD ratios around 1:1 to 1:2 are consistent with balanced CBD cultivars under optimized conditions. Flowering windows of roughly 65 to 75 days are also typical for haze-based CBD crosses that have been selected for slightly shorter maturation than classic Amnesia Haze.
As with all cannabis data, environment, phenotype, and handling can swing outcomes by meaningful margins. Growers are encouraged to validate with local testing and tailor inputs to their specific setup. Consumers should consult COAs when available to verify batch potency and terpene content.
Buyer and Patient Tips
If purchasing flower, look for clear citrus-pine aroma and a bright, zesty top note that persists after grinding. Request certificates of analysis when possible and seek batches with balanced THC and CBD levels if aiming for daytime clarity. For edibles and tinctures, start with low doses and consider CBD-leaning ratios for new or sensitive users.
Growers selecting seeds should plan for a trellised scrog and moderate stretch management. Phenohunt for ratio and terpene expression rather than chasing highest total cannabinoids, since the balance is the point here. Keep an eye on late-flower humidity due to the longer bloom and elongated cola structure.
Vapers targeting flavor can set temperatures between 175 and 190 Celsius to emphasize the citrus and floral terpenes. Joint and bong users may notice the peppery caryophyllene on the finish; a slow, cool burn preserves the top notes. For concentrates, low-temp rosin and long, cool cures can retain the nuanced haze bouquet without harshness.
