Amulet OG is an autoflowering hybrid developed by Night Owl Seeds, a boutique breeder known for crafting terpene-rich, resin-heavy autos. The breeder’s catalog often blends elite photoperiod genetics with robust ruderalis lines to stabilize fast, compact plants that retain modern potency. In keeping with that approach, Amulet OG was built to capture an OG-forward profile within a true ruderalis/indica/sativa framework. The result is a cultivar that moves from seed to harvest rapidly while aiming to preserve the classic gas, pine, and lemon signatures associated with OG families.
Night Owl Seeds has not publicly disclosed the full parent list for Amulet OG, an increasingly common practice for protecting proprietary selections. What is clear is that the cultivar’s architecture and aroma strongly suggest an OG-leaning base backed by a vigorous autoflowering engine. Growers routinely note the combination of squat, dense nodes with a noticeable mid-flower stretch, which is consistent with indica-leaning hybrids powered by sativa influence. This balance often positions Amulet OG as a productive yet manageable plant for both small tents and larger rooms.
The creation of an OG-flavored auto that finishes in roughly 10–12 weeks from sprout responds to a market trend favoring faster turns without sacrificing quality. Over the last five years, autos have closed much of the potency and terpene gap with photoperiods, with many lines now achieving 18–25% THC when well-grown. Amulet OG participates in that new generation of performance, with reports from experienced cultivators describing high trichome density and vivid terpene expression. The cultivar has also gained attention for its extraction potential, a hallmark of Night Owl’s resin-forward breeding ethos.
Because Amulet OG is distributed as seeds rather than clones, phenotypic variation exists, but stability is considered strong for an auto with complex hybridization. Phenotypes that lean more toward the OG side typically finish slightly later and denser, while quicker phenos exhibit more ruderalis influence and open structure. Across community logs, uniformity in terpene categories appears consistent even when structure varies. This consistency aligns with Night Owl’s broader reputation for selecting stable, aromatic autos that perform in diverse environments.
Genetic Lineage and Classification
Amulet OG’s stated heritage is ruderalis/indica/sativa, which places it squarely in the modern autoflowering hybrid category. The ruderalis contribution drives the automatic flowering trait and compresses the lifecycle to approximately 70–90 days from sprout. Indica influence expresses as broad-leaf traits, dense internodes, and a calm, body-forward finish to the effects. Meanwhile, sativa influence contributes the vertical stretch window and the mental clarity many users describe in the early phase of the experience.
While exact parents have not been publicly disclosed, sensory and structural clues point to an OG Kush–descended or OG-influenced backbone. Classic OG markers include a fuel-forward top note intertwined with pine, lemon zest, and earthy spice. The cultivar’s resin production and calyx-to-leaf ratio also resemble OG-descended lines, which typically reward dialed-in environmental control with high bag appeal. This triangulation of traits is part of why experienced growers often place Amulet OG in the broader OG family tree despite the lack of explicit pedigree disclosure.
In practical terms, categorizing Amulet OG as a balanced hybrid is most accurate for grow planning and expectations. Early vegetative growth can be compact, but once preflower triggers, a predictable stretch phase usually doubles plant height in 10–14 days. That stretch is shorter than a sativa-dominant auto yet more pronounced than a pure indica auto, allowing for flexible training and spacing. This balance aids in canopy management, especially when limited by tent height or light intensity.
From a chemotypic perspective, Amulet OG aligns with Type I cannabis (THC-dominant) with minor cannabinoids present at trace-to-moderate levels. Community reports and analogous OG autos commonly show total THC ranges in the high teens to low-mid 20s with CBD typically below 1%. Such chemotypes situate Amulet OG for recreational potency and symptom relief where THC is a primary driver. For medical users seeking higher CBD, pairing with a CBD-dominant cultivar or blending extracts may be more suitable.
Visual Morphology and Bag Appeal
Amulet OG typically develops medium-height frames with stout branches and a symmetrical canopy, especially in 3–5 gallon containers. Average indoor heights land around 24–36 inches (60–90 cm), with some phenotypes reaching 40 inches (100 cm) under high PPFD and ample root volume. Internodal spacing is tight in early veg, leading to stacked colas by mid-flower when the stretch consolidates. The plant often finishes with a spear-shaped central cola and several secondary tops at near-equal height when trained properly.
Buds are dense, golf-ball to cola-length, and heavily calyxed, which improves both trim efficiency and visual density after cure. Trichome coverage is a standout trait; most growers report a thick, frosted veneer across bracts and sugar leaves that signals extract-friendly resin glands. Pistils begin a bright tangerine or pumpkin hue and darken to copper as maturity approaches. When environmental conditions are cool late in flower, anthocyanins can push faint purples or lilacs in some phenos, though green-gold is the most common finish.
Leaf morphology skews broad but not overly wide, reflecting the hybrid nature of the line. Fan leaves typically present with 7–9 blades early, narrowing slightly as the plant stretches into bloom. The calyx-to-leaf ratio trends favorable, reducing final trim time and preserving trichome coverage on the flowers rather than the sugar leaf. After cure, properly handled buds remain slightly spongy yet dense, an indicator of optimal moisture content in the 10–12% range.
Bag appeal is enhanced by the contrast between silver trichomes and deep green calyxes, punctuated by fiery pistils. Broken apart, the flower exhibits bright resin heads and a subtle stickiness that signals freshness. Under LED lighting, a subtle opalescent shimmer is common, a hallmark of high-density glandular trichomes. These traits collectively position Amulet OG as visually competitive with photoperiod OG cuts when grown with strong environmental control.
Aroma and Bouquet
Amulet OG’s aromatic footprint is OG-forward with a modern twist, blending fuel, pine needles, and lemon rind with a creamy, earthy undercurrent. On the dry rub, expect a sharp top note reminiscent of gasoline or solvent, quickly rounded by citrus-lime and cracked peppercorn. As the flower opens, forest-floor and wet-stone minerality come forward, a profile often associated with myrcene and humulene synergy. The background shows a faint sweetness that reads as vanilla wafer or light caramel in some phenotypes.
During flowering, the room note can be assertive, especially from week 5 onward, so carbon filtration is recommended for privacy. In side-by-side grows, growers often rate odor intensity as medium-high to high on a five-point scale. The terpene intensity continues to build through late flower, peaking near harvest when total terpene content often reaches its maximum. After a slow dry and cure, the bouquet shifts toward more layered citrus-pine with less overt fuel burn in the nostrils.
When ground, volatile top-note terpenes volatilize rapidly, so a brief rest before rolling can improve flavor transfer. The grind releases bright limonene and pinene tones with a spicy-caryophyllene kick that can tickle the sinuses. Some users perceive an herbal menthol edge, likely from minor terpenes like eucalyptol present in trace amounts. In sealed jars, the headspace reads clean and piney, with a consistent OG “fume” that signals potency.
For those sensitive to strong aromas, expect higher-than-average room permeation compared to fruit-forward autos. Dual-stage filtration, a sealed tent, and negative pressure help reduce odor escape by 70–90% compared to passive setups. Using ozone or ionizers is generally discouraged in the grow space as they can degrade terpenes and harm plants. Instead, rely on oversized carbon filters and frequent air exchanges to maintain discretion without sacrificing aroma quality.
Flavor and Mouthfeel
The flavor of Amulet OG mirrors its aroma but adds distinct layers during combustion or vaporization. The initial inhale delivers pine resin and lemon peel, followed by a diesel-like bite that OG fans typically seek. As the hit settles, earthy, slightly creamy notes smooth the palate, reducing harshness when properly cured. On the exhale, expect lingering citrus, peppery spice, and a hint of cedar or sandalwood.
Vaporization at 175–190°C (347–374°F) preserves limonene, pinene, and myrcene for a bright, terp-rich experience. Lower temperatures highlight zesty citrus and fresh pine, while higher temperatures emphasize earthy spice and fuel. Many users find the 185°C (365°F) range balances vapor density with terpene preservation, minimizing throat irritation. In joints, a slow, even burn and light gray ash indicate a clean flush and proper dry/cure.
Mouthfeel is medium-bodied with a slightly resinous coating that carries flavor between pulls. The smoke can be assertive at high temperatures, so smoothness depends heavily on the cure and moisture content. Flower dried at 18–20°C (64–68°F) and 55–60% RH for 10–14 days typically retains more volatile terpenes and reduces harshness. A properly burped cure of 3–6 weeks further knits citrus, pine, and spice into a cohesive profile.
Compared to fruit or dessert autos, Amulet OG is less sugary but more complex and persistent on the palate. Users who appreciate classic West Coast gas with an herbal twist will find the flavor both nostalgic and modern. For extracts, rosin typically concentrates the diesel-pine axis, with fresh-press preserving brighter citrus top notes. Live rosin from fresh frozen material often showcases the cleanest lemon-pine interplay, especially if harvested at peak terpene ripeness.
Cannabinoid Composition
Amulet OG presents as a THC-dominant Type I chemotype, with community-reported ranges placing total THC commonly between 18–24% by dry weight when grown and cured optimally. Some high-performing phenotypes under strong LEDs and ideal VPD have reportedly tested in the mid-20% range, though strain-specific third-party COAs remain limited in the public domain. CBD typically appears below 1%, often around 0.1–0.5%, preserving a psychoactive forward profile. Minor cannabinoids such as CBG and CBC are usually detected in the 0.2–0.8% and 0.1–0.3% ranges, respectively, contributing to entourage effects.
Converted to mg/g, a 20% THC flower corresponds to roughly 200 mg THC per gram of dried material. With decarboxylation efficiency near 87–90% under typical edible preparation conditions, the effective THC yield for infusion is about 174–180 mg/g. Such calculations help medical and home users target dose consistency, particularly when preparing oils or tinctures. For vaporization or smoking, bioavailability varies widely but is commonly estimated between 10–35%, depending on device, technique, and individual physiology.
For home testing, readouts from consumer-grade devices can deviate by 10–20% compared to certified labs, so treat those values as directional. Environmental stress, harvest timing, and curing protocols can swing potency by several percentage points. Late harvesting with high amber trichome ratios can increase perceived sedative qualities despite similar total THC, likely due to oxidized cannabinoids and shifts in terpenoid balance. Conversely, earlier harvests with mostly cloudy trichomes may feel more stimulating even if lab values are unchanged.
Users seeking more balanced THC:CBD ratios can blend Amulet OG with a CBD-dominant cultivar at ratios such as 1:1 or 2:1 to moderate intensity. This approach is common among patients who want OG flavor with a gentler ceiling on psychoactivity. In concentrates, Amulet OG’s resin density often translates to high potencies exceeding 65–75% total cannabinoids in solventless rosin, depending on input quality. Such concentrates should be dosed carefully, as one 0.05 g dab at 70% THC delivers roughly 35 mg THC in a single inhalation session.
Terpene Profile and Chemistry
Growers and enthusiasts consistently report a terpene stack led by myrcene, limonene, and beta-caryophyllene, supported by alpha-pinene, humulene, and linalool in trace-to-moderate amounts. In robust, well-grown samples, total terpene content typically falls around 1.5–3.5% by weight, aligning with contemporary OG-influenced autos. Typical ranges observed in analogous OG autos suggest myrcene at 0.4–0.9%, limonene at 0.3–0.7%, and beta-caryophyllene at 0.2–0.6%. Secondary contributors like alpha-pinene at 0.1–0.3%, humulene at 0.05–0.15%, and linalool at 0.05–0.2% round out the aromatic profile.
From a sensory perspective, limonene supports the lemon-zest top note, while alpha-pinene accounts for crisp pine and a perceived airway-clearing brightness. Myrcene is often associated with earthy, musky undertones that read as forest floor and can contribute to a relaxing baseline. Beta-caryophyllene imparts peppery spice and, uniquely among terpenes, binds to CB2 receptors, which may influence inflammation signaling. Humulene adds an herbal, woody edge often described as hoppy or slightly bitter, helping to balance sweetness.
Environmental control has a measurable impact on terpene retention. Studies show that slow drying at moderate temperatures (18–20°C) and RH (55–60%) preserves monoterpenes like limonene and pinene better than rapid or warm drying. Excess heat accelerates terpene volatilization, potentially dropping measured totals by 20–40% compared to gentler protocols. In addition, late-stage light intensity that is too high can increase volatilization at the canopy surface; dialing PPFD down 10–15% during the final week may improve retention.
For extraction, fresh frozen material tends to preserve a higher proportion of monoterpenes relative to cured input. Live rosin from Amulet OG typically exhibits brighter citrus and pine, whereas cured rosin presents denser fuel and spice. Both profiles benefit from the cultivar’s resin density, with many extractors targeting 18–24% press yields from quality flower. As always, individual outcomes depend on phenotype, cultivation, and handling from harvest to press.
Experiential Effects and Use Cases
Amulet OG is generally experienced as a balanced yet potent hybrid with a clear OG backbone. The onset after inhalation is typically felt within 2–10 minutes, beginning with a bright head lift and sensory sharpened focus. As the session continues, a grounding body calm emerges, smoothing edges without immediate couchlock at moderate doses. Peak effects often appear at 30–60 minutes and taper over 2–3 hours, with residual calm lasting longer in sensitive users.
At lighter doses, many report enhanced mood and stress reduction suitable for late afternoon or early evening use. The cultivar’s pinene and limonene tilt contribute to a lucid top end, helping conversations flow and creative tasks feel approachable. With larger doses, the caryophyllene-myrcene base becomes more noticeable, increasing heaviness and potentially encouraging restful stillness. Users prone to anxiety with high-THC strains may prefer microdoses of 2–5 mg THC equivalent to gauge personal response.
Common side effects include dry mouth and dry eyes, reported by roughly 30–50% of users across THC-dominant strains. Transient increases in heart rate can occur in sensitive individuals, especially with rapid inhalation of large hits. Overconsumption may lead to temporary dizziness or overwhelming intoxication; stepping down intake or adding CBD can help moderate intensity. Hydration, paced inhalation, and a comfortable environment reduce the likelihood of discomfort.
Use cases reported by consumers include winding down after work, social unwinding, and pairing with films, music, or light gaming. Some find Amulet OG productive for task-oriented chores during the first hour at low doses, thanks to the clean mental lift. Others lean on its physical relaxation for post-exercise recovery sessions or stretching. For sleep support, moving dosage closer to bedtime and allowing the sedative tail to land is a common strategy.
Potential Therapeutic Applications
While clinical evidence for specific strains is limited, Amulet OG’s chemotype and terpene balance suggest potential utility across several symptom domains. THC-dominant flower with caryophyllene and myrcene is commonly used by patients for transient pain, stress, and insomnia. Limonene and pinene may contribute to mood elevation and perceived mental clarity, though responses are highly individual. As always, medical decisions should involve a qualified clinician, especially for those with comorbid conditions.
For pain and musculoskeletal tension, inhaled doses of 2–10 mg THC equivalent often provide rapid relief within minutes. Patients with higher tolerance may escalate to 10–20 mg per session, monitoring for side effects like sedation or tachycardia. Inflammatory discomfort may benefit from the CB2 activity associated with beta-caryophyllene, though human data remain preliminary. Combining Amulet OG with stretching, heat therapy, or mindfulness techniques can enhance multimodal relief.
For anxiety-prone users, ultra-low dosing strategies can reduce the risk of paradoxical anxiety that sometimes accompanies high-THC strains. Microdosing 1–2 mg THC or blending with a CBD-dominant cultivar at a 1:1 or 2:1 CBD:THC ratio is a common approach. Many report that such blends preserve the OG flavor while delivering a gentler psychological profile. Note that edibles have delayed onset (45–120 minutes) and longer duration (4–8 hours), so start low and wait before redosing.
Sleep support may be achieved by timing the session 60–90 minutes before bed, allowing the initial head lift to transition into body relaxation. Late-harvest phenotypes with slightly more amber trichomes can feel more sedating, though data on exact correlations remain mixed. Patients sensitive to next-day grogginess may prefer inhaled forms over edibles to manage duration. Consistency in routine, dose, and strain selection often yields better outcomes than sporadic use.
Cultivation Guide: From Seed to Cure
Amulet OG is an autoflower bred by Night Owl Seeds, leveraging ruderalis genetics to flower automatically regardless of light cycle. Typical seed-to-harvest timelines range 70–85 days, with rare phenotypes finishing as quick as ~65 days or stretching to ~95 days under cooler conditions. Indoors, yields of 350–550 g/m² are achievable in dialed-in environments, while single plants in 3-gallon pots commonly produce 70–150 g. Outdoors, expect earlier finishes in warm climates and reduced yields in short, cool seasons; a protected greenhouse can extend viability and reduce weather risk.
Environment. Maintain day temperatures of 24–28°C (75–82°F) in veg and 22–26°C (72–79°F) in flower, with nighttime dips of 2–4°C to manage stretch and preserve color. Relative humidity should start at 60–70% in early veg, taper to 50–55% mid-flower, and finish at 40–45% late-flower to mitigate botrytis risk. Target VPD of 0.8–1.2 kPa in veg and 1.2–1.5 kPa in bloom for optimal gas exchange. Provide robust air movement and exchange; two oscillating fans and a properly sized carbon filter help control odor and microclimates.
Lighting. As an autoflower, Amulet OG performs well under 18/6 or 20/4 schedules from sprout to harvest. Aim for PPFD 350–500 µmol/m²/s in early veg, 500–700 in late veg, and 700–900 in flower, adjusting for canopy response. This corresponds to approximate DLI targets of 20–30 mol/m²/day in veg and 40–50 mol/m²/day in bloom. In the final 7–10 days, reducing intensity by ~10–15% can improve terpene retention without sacrificing yield.
Media and nutrition. In coco, run pH 5.8–6.2 with EC 1.0–1.6 mS/cm, starting lighter and ramping as demand increases. In soil, pH 6.2–6.8 is ideal; living soil or amended organics can supply a slow-release nutrient base that autos often appreciate. Early nutrition should favor a mild N input; many autos perform best with 10–20% less nitrogen than comparable photoperiods. A general N-P-K arc of 3-1-2 in early veg transitioning to 1-2-3 in bloom works well, with added calcium and magnesium (100–150 ppm Ca, 50–80 ppm Mg) under LEDs.
Irrigation. Autos prefer consistent but not waterlogged conditions; overwatering in early life is the most common yield limiter. In coco, multiple small irrigations per day at 10–20% runoff maintain root zone stability. In soil, water thoroughly to slight runoff, then allow the top inch to dry before the next event. Keep root zone temperatures near 20–22°C (68–72°F) for robust microbial activity and nutrient uptake.
Training and plant handling. Low-stress training (LST) is the safest and most effective method, beginning around day 14–18 when the third or fourth node has formed. Gentle bending and tie-downs open the canopy and promote multiple tops without stalling. If topping, do it once and early (day 14–18) only on vigorous individuals; slower phenos should be left untopped. Defoliation should be conservative—remove large fans that block bud sites around weeks 3–5, and avoid heavy stripping late in flower to preserve photosynthetic capacity.
Pest and disease management. Maintain cleanliness and quarantine new plant material to avoid infestations. Yellow sticky cards can reduce adult fungus gnats; pairing with Bacillus thuringiensis israelensis (BTi) drenches can cut larval populations by 70–90% over two weeks. For spider mites or thrips, weekly scouting and preventative sprays with botanicals like neem or rosemary-based products during early veg can be effective. Ensure sprays cease before mid-flower to protect trichomes and prevent residue on buds.
Feeding milestones. Weeks 1–2: light feed at EC 0.6–0.9 (300–450 ppm 500-scale), focusing on root stimulants and gentle Ca/Mg. Weeks 3–4: ramp to EC 1.0–1.2 as preflower starts, introduce bloom micronutrients. Weeks 5–7: peak demand; EC 1.3–1.6 with increased K and P and steady Ca/Mg under LED lighting. Final 10–14 days: taper intensity and consider reducing nitrogen; many growers switch to plain, pH-balanced water in inert media, while living soil growers simply stop top-dressing.
Harvest timing. For a balanced hybrid effect, target trichomes at ~5–15% amber with the remainder mostly cloudy. Pistil coloration alone is insufficient; inspect resin heads under 60–100× magnification. Harvest windows often land between days 75–85 from sprout for the densest expressions, with earlier phenos finishing closer to 70 days. Cooler final week temperatures can tighten buds and help color development.
Drying and curing. Hang branches or whole plants at 18–20°C (64–68°F) and 55–60% RH with gentle airflow for 10–14 days. Aim for stems that snap while smaller ones still bend, indicating a 10–12% moisture content. Jar cure at 62% RH, burping daily for the first week, then weekly thereafter; water activity between 0.55–0.62 is ideal for stability. Flavor and smoothness often improve notably between weeks 3 and 6 of cure, with terpene cohesion peaking around week 8.
Yields and quality optimization. In a 2×4 ft tent with 240–300 W of efficient LED lighting, two to three Amulet OG plants in 3-gallon pots commonly produce 200–350 g combined. A uniform canopy, consistent VPD, and proper timing of LST can push results toward the high end of that range. CO2 enrichment to 900–1,100 ppm in sealed rooms can add 10–20% biomass if light, nutrition, and irrigation are fully optimized. For extraction, cold room processing and minimal agitation protect trichome heads and preserve the diesel-citrus profile.
