Alien Blackout is a mostly indica cultivar developed by Moscaseeds, a breeder recognized for stabilizing classic North American and Afghan-leaning lines. The strain’s name hints at its heavy, lights-out body effect, which aligns with its indica dominance and resin-forward morphology. While the breeder has not widely publicized a formal release whitepaper for this cultivar, its presence in private gardens and small-batch drops has grown steadily since the mid-to-late 2010s. In that time, it has developed a reputation among hobbyists for dense buds, dark coloration, and evening-ready potency.
In collector circles, Alien Blackout is often discussed alongside other Moscaseeds projects that favor compact structure and flavorful resin. Growers frequently compare it to classic Afghan and Kush expressions, citing similar internodal spacing and calyx density. This narrative fits Moscaseeds’ broader breeding approach of refining vigorous, terpene-rich, indica-leaning plants that perform well indoors. As a result, Alien Blackout has become a go-to option for cultivators seeking a dependable nightcap cultivar with strong bag appeal.
Market-wise, indica-leaning hybrids remain highly sought after for nighttime relief and stress management, a niche that Alien Blackout readily fills. In dispensary lineup analyses, heavy indica-style offerings consistently maintain shelf presence thanks to consumer demand for sleep and pain relief solutions. In homegrow communities, the strain’s dense flower structure and resin production also make it attractive for hash-making and rosin pressing. This combination of consumer appeal and processing versatility has helped Alien Blackout carve out a stable place in many gardens.
Although formal, large-scale lab data sets specific to Alien Blackout are limited, community reports describe consistent potency and a relatively forgiving growth curve. These anecdotal reports suggest the strain was selected with practical cultivation in mind rather than purely exotic lineage hype. That makes sense given Moscaseeds’ track record of workhorse genetics intended for real-world gardens. In short, Alien Blackout’s history is less about marketing headlines and more about dependable, indica-forward performance that meets cultivator needs.
Genetic Lineage
Alien Blackout’s exact parentage has not been officially published by Moscaseeds, and responsible reviewers should avoid asserting a definitive cross without breeder confirmation. The naming convention suggests a lineage that pulls from classic Alien family aromatics with a heavy, blackout-caliber finish, likely anchored by Afghan or Kush ancestry. These backgrounds typically confer broad leaves, short internodes, and stout lateral branching, traits widely reported in grow logs for Alien Blackout. Such features are consistent with a mostly indica genetic base.
Given the breeder’s catalog history and the cultivar’s observed phenotype, it is reasonable to infer strong Afghan-derived resin traits and possibly Skunk or OG-type influences in the background. Afghan lines are renowned for high calyx-to-leaf ratios and thick trichome carpets, both frequently noted in Alien Blackout batches. Skunk or OG influences would help explain the spicy-earth and fuel-tinted notes that growers describe in late flower and after cure. While these details are informed, they remain educated inference rather than a disclosed recipe.
Indica-leaning hybrids like Alien Blackout commonly share a genomic tilt toward alleles associated with shorter flowering windows and sedative chemotypes. Growers consistently report a finishing time in the 56–63 day range indoors, which matches many Afghan-Kush architectures. The plant’s tendency to stack dense, weighty colas also aligns with that heritage, especially when grown under high PPFD and controlled VPD. These traits collectively support an indica-majority lineage estimate of roughly 70–85% indica expression in most phenotypes.
Until the breeder releases definitive parentage, cultivators should evaluate Alien Blackout on phenotype and chemotype rather than pedigree alone. This practical approach mirrors the reality of many modern hybrids where performance trumps lineage branding. By focusing on observable growth habits, resin output, aroma, and effect, cultivators can select keepers that fit their goals. In this way, the strain’s utility eclipses the need for a fully disclosed family tree.
Appearance
Alien Blackout forms compact, bushy plants with broad, dark green leaves that often display deep purpling late in flower. Internodal spacing typically measures 2–4 centimeters on trained branches, allowing for tight bud stacking. Mature colas are dense with a high calyx-to-leaf ratio, frequently around 2:1 or better when dialed in. This morphology lends itself to a tidy trim and strong bag appeal.
The strain’s coloration is a notable talking point, with phenotypes capable of expressing near-black hues under cooler night temperatures. A night drop to 16–18°C during the last two weeks of flower can coax anthocyanin expression without stressing the plant, provided VPD remains in check. Pistils range from burnt orange to deep rust, contrasting dramatically with the dark calyxes. Under strong LED lighting, trichome heads can glisten with a silver frost that photographs exceptionally well.
Trichome coverage is abundant, with bulbous capitate-stalked glands concentrated along sugar leaves and bracts. Growers commonly observe trichome head diameters in the 90–110 micron range, a sweet spot for ice-water hash and dry sift. Resin production increases sharply from week five onward, with a noticeable jump in head density between days 42 and 56. This timeline supports targeted harvest planning for different extract textures.
Dried flowers cure down into hefty, golf ball to small soda-can nugs with minimal stem weight. A properly executed cure preserves a matte-satin sheen rather than a dull finish, indicating healthy resin and low handling damage. Expect buds to feel firm to the squeeze at 0.58–0.62 water activity, a range that reduces mold risk while keeping terpenes vibrant. Overall, Alien Blackout’s physical traits speak to its indica-dominant heritage and resin-forward selection.
Aroma
Alien Blackout’s aromatic profile is layered and assertive, often opening with dark berry, cocoa, and damp earth. Beneath that, many noses pick up peppery spice and a fuel-adjacent sharpness reminiscent of OG-skewing lines. As the flowers ripen, a sweet incense quality can emerge, especially after a slow dry and four-week cure. The overall bouquet reads heavy, nocturnal, and dessert-like without being cloying.
Terpene analysis on comparable indica-leaning cultivars indicates likely dominance of beta-myrcene, beta-caryophyllene, and limonene, supported by humulene and linalool. When quantified, total terpene content in well-grown craft batches often lands around 1.5–3.0% by dry weight, with beta-myrcene frequently in the 0.6–1.2% range. Beta-caryophyllene commonly presents at 0.3–0.8%, contributing to the peppered earth profile. Limonene is typically measured between 0.2–0.6%, lifting the top notes with a citrusy brightness.
Environmental controls play a noticeable role in aroma fidelity for Alien Blackout. Maintaining flower-room daytime temperatures at 24–26°C and RH 45–50% helps preserve volatile compounds that otherwise flash off under heat. A slow dry at 15–18°C and 58–62% RH for 10–14 days retains more monoterpenes, translating to a richer nose on the jar. Heavy-handed drying above 22°C or sub-45% RH often correlates with flatter, hay-like notes.
Growers also report that late-flower sulfur management and clean irrigation practices improve the aroma’s clarity. Avoiding high-sulfur foliar inputs past week three of flower reduces harshness and preserves sweetness. Similarly, consistent runoff to 10–20% in soilless systems can prevent salt buildup that dulls terpene expression. The result is a bouquet that remains distinct from grind to exhale.
Flavor
On the palate, Alien Blackout delivers a fusion of dark fruit, semi-sweet chocolate, and black pepper, followed by a lingering earthy finish. Some phenotypes tilt toward a gas-and-grape impression when combusted, while vaporization tends to emphasize cocoa and berry. The mouthfeel is dense and slightly resinous, coating the tongue and persisting through the session. Ash burns light gray to white when the cure and feed schedule are on point.
Temperature strongly influences flavor expression, particularly in vaporizers. At 175–185°C, berry and citrus-limonene notes are most prominent, with a gentle sweetness. At 190–200°C, peppered spice and cocoa-fatty undertones rise as caryophyllene and heavier volatiles dominate. Beyond 205°C, flavors trend earthy and woody, with diminishing fruit character and increasing harshness.
Minimizing chlorophyll and preserving monoterpenes requires patience in post-harvest handling. A 10–14 day dry followed by a 4–8 week cure at 16–18°C and 58–62% RH maintains flavor stability. Ideal jar water activity between 0.55 and 0.62 prevents terpene flattening while deterring microbial growth. Regular burping in the first two weeks helps exchange off-gassed volatiles and moisture for a cleaner finish.
Nutrient practices also affect the smoke. Keeping nitrogen inputs restrained in late flower and ensuring adequate calcium and magnesium support can reduce harshness. A 7–10 day, low-EC finish (EC 0.8–1.0 in hydro, or water-only in final week for living soil) often correlates with smoother combustion. These small practices cumulatively protect the strain’s signature dessert-and-spice flavor.
Cannabinoid Profile
Alien Blackout is typically potent, with most reports placing total THC in the 18–26% range by dry weight when grown under optimized conditions. CBD is usually minimal, commonly quantified between 0.05–0.8%, which situates the strain squarely in the THC-dominant category. Minor cannabinoids such as CBG and CBC are occasionally detected, with CBG often in the 0.2–1.0% window depending on harvest timing. These figures align with many indica-leaning modern hybrids.
For dosing context, a gram of flower at 22% total THC contains roughly 220 mg THC in acid form (predominantly THCA pre-decarboxylation). After decarboxylation, the theoretical conversion uses a factor of 0.877, yielding about 193 mg of neutral THC if fully converted. Under typical consumption, decarb efficiency and combustion losses result in less than 100% bioavailability, often in the 10–35% range for inhalation. This means subjective effects can vary widely despite similar potency labels.
In edibles or concentrates derived from Alien Blackout, normalized potency can be much higher. Hydrocarbon or rosin extracts often test at 65–80% total THC, depending on input quality and method. Given the strain’s resin density and trichome head size, rosin yields of 18–24% from fresh-cured flower are realistic, with single-source hash rosin sometimes exceeding 70% total THC. Users should titrate carefully when transitioning from flower to concentrates.
Because lab results fluctuate by environment, harvest timing, and processing, the ranges above should be treated as typical rather than absolute. Earlier harvests skew toward a brighter, more energetic effect with slightly lower total THC due to less complete resin maturation. Later harvests with more amber trichomes may read marginally higher in total THC while pushing a more sedative effect. Accurate profiling requires batch-specific testing to confirm exact major and minor cannabinoid values.
Terpene Profile
Alien Blackout’s terpene distribution commonly centers on beta-myrcene, beta-caryophyllene, and limonene, forming a dark fruit and spice core. In dialed-in indoor runs, total terpenes of 1.5–3.0% are achievable, with myrcene often representing 30–45% of the total terpene fraction. Caryophyllene typically contributes 15–30%, supporting a peppered, earthy backbone. Limonene’s 10–20% share provides lift and perceived sweetness on the nose and tongue.
Secondary terpenes often include humulene, linalool, and occasionally farnesene or ocimene in trace to moderate amounts. Humulene at 0.05–0.2% adds herbal dryness that can balance sweeter notes. Linalool in the 0.03–0.15% range supports floral and lavender facets that become more apparent with a slow cure. Farnesene, when present at 0.02–0.1%, may contribute to the apple-skin brightness detectable in some phenos.
Terpene preservation hinges on environmental discipline from late flower through cure. Keeping canopy temperatures near 24–26°C and leaf surface temperatures under 28°C reduces volatilization of monoterpenes like myrcene. A dry room at 15–18°C and 58–62% RH slows evaporation rates, measurable as a reduced terpene loss percentage over time. Studies on aroma compound retention show that cooler, stable conditions can cut volatilization losses by double-digit percentages compared to hot, fast dries.
It is also worth noting that enantiomeric composition can influence perception. D-limonene is the dominant citrus isomer in most cannabis samples and reads as bright orange or lemon zest to many users. Alpha-pinene and beta-pinene, if present in small amounts, can add pine and airflow-clarity sensations during inhalation. Together, these minor contributors round out Alien Blackout’s dessert-and-spice identity into a multidimensional experience.
Experiential Effects
Alien Blackout earns its name with a deeply relaxing, body-heavy experience that most users reserve for late afternoon or night. Onset after inhalation typically occurs within 2–10 minutes, with peak effects around 30–45 minutes. Subjectively, many report a warm, tension-melting heaviness paired with a calm, unhurried mindset. The headspace is tranquil rather than psychedelic, though higher doses can become intensely sedative.
Euphoria tends to be grounded and contented rather than soaring, which complements the strain’s physical relief. A recurring note from users is improved comfort in the back, shoulders, and hips, consistent with indica-dominant muscle-relaxant qualities. Appetite stimulation is common, often emerging 45–90 minutes post-consumption as the session deepens. Dry mouth and dry eyes are the most frequently cited mild side effects.
At moderate doses, expect 2–4 hours of primary effects, depending on tolerance and delivery method. Vaporization produces a clear onset and a slightly shorter tail than combustion, while concentrates amplify body load and sedation. New users or those sensitive to THC should start with small inhalation amounts and wait at least 15 minutes before redosing. Many experienced consumers reserve Alien Blackout for wind-down rituals, movies, or pre-sleep routines.
In social settings, Alien Blackout can be quietly convivial but is more often a couch companion than a party starter. Focus-intensive tasks may feel slow, and driving or operating machinery should be avoided entirely while under the influence. For creative pursuits, the strain may support low-tempo, tactile activities like sketching or music listening rather than rapid ideation. Overall, it excels where calm, comfort, and deep relaxation are the goals.
Potential Medical Uses
While individual responses vary, Alien Blackout’s indica-dominant profile suggests several potential therapeutic applications. Users commonly report relief for muscle tension, generalized body aches, and stress-related discomfort. In the context of sleep, THC-dominant cultivars can shorten sleep latency for some individuals, with meta-analytic estimates showing modest improvements on the order of single-digit minutes. The strain’s sedative arc aligns with bedtime routines for people who respond well to THC for insomnia.
For anxiety, outcomes are dose-dependent and highly personal. Lower doses may help quiet ruminative thoughts, while higher doses can occasionally exacerbate anxiety in THC-sensitive individuals. The presence of myrcene, linalool, and beta-caryophyllene is often associated with calming effects, though evidence remains suggestive rather than conclusive. Users should titrate slowly and consider set and setting when exploring Alien Blackout for mood support.
Pain management is a frequently cited use case, particularly for neuropathic tingling, arthritic stiffness, or post-exertional soreness. Although cannabis is not a cure, some patients report clinically meaningful reductions in perceived pain intensity when using THC-dominant products. Practical dosing strategies often start with 1–2 inhalations or low-dose oral preparations (1–2.5 mg THC), titrating upward as needed and tolerated. Combining Alien Blackout with non-pharmacologic strategies like heat therapy or stretching may enhance comfort.
Appetite stimulation is another consistent effect that can be beneficial for people dealing with reduced appetite. Inhaled THC can trigger noticeable appetite signals within an hour, potentially supporting caloric intake when medically indicated. As always, medical decisions should be made with a clinician who understands cannabis pharmacology and the patient’s full medication list. This is especially important due to possible interactions with CNS depressants and other medications.
Cultivation Guide
Alien Blackout’s mostly indica heritage from Moscaseeds translates to a compact, high-resin plant that rewards disciplined environment control. Indoors, a final height of 70–120 centimeters is typical from seed with topping, while clones tend to finish even shorter. Veg for 3–5 weeks to fill a 0.6–1.0 square meter canopy per plant under training. Expect an indoor flowering window of 56–63 days for most phenotypes, with some keepers finishing as early as day 54 when pushed.
Lighting and canopy management are central to yield and quality. Aim for 600–900 µmol/m²/s PPFD in late veg and 900–1,200 µmol/m²/s in mid-to-late flower for CO2 at ambient levels. With supplemental CO2 at 800–1,200 ppm, PPFD can be increased to 1,200–1,400 µmol/m²/s if VPD and irrigation are dialed. Maintain daily light integral around 35–45 mol/m²/day in flower for dense stacking without overstress.
Temperature targets of 24–27°C in lights-on and 18–22°C in lights-off keep metabolism brisk while minimizing stress. Relative humidity at 55–65% in veg and 40–50% in flower supports stomatal function and reduces botrytis risk in dense colas. For VPD, run 0.8–1.2 kPa in veg and 1.1–1.5 kPa in flower, tapering toward the higher end in late bloom to prevent microclimates. Leaf surface temperature should be monitored with an IR thermometer to avoid overlighting.
In soilless systems, feed at EC 1.2–1.6 in veg and 1.6–2.0 in peak flower, depending on cultivar response and water quality. Maintain pH 5.8–6.2 in hydro and coco, and 6.2–6.6 in soil. A balanced macro profile that moves from higher nitrogen in early veg (e.g., 120–150 ppm N) to increased potassium in late flower (e.g., 220–280 ppm K) supports bud density and oil production. Calcium 150–180 ppm and magnesium 50–70 ppm are good baselines for preventing common deficiencies under high-intensity LEDs.
Living soil growers can target 3–5% organic matter with robust aeration (30–40% perlite, pumice, or rice hulls) and regular top-dressing. Incorporate calcium-rich amendments and modest potassium sulfate in mid flower to back resin formation. Use microbial teas judiciously before week three of flower, then switch to water-only plus microbial inoculants as needed. In living systems, a final water-only period of 10–14 days often yields a clean, smooth finish.
Training methods that pair well with Alien Blackout include topping once or twice, low-stress training to open the center, and SCROG for even light penetration. The strain’s internode spacing favors a multi-top manifold or mainline approach, creating 6–10 productive sites per plant. Avoid over-defoliation; instead, use selective leaf removal at weeks three and six of flower to clear shadowed sites while preserving photosynthesis. This balanced approach can increase yield by 10–20% versus untrained plants in side-by-side runs.
Pest and disease management should anticipate powdery mildew and botrytis risk due to the cultivar’s dense floral structure. Maintain strong airflow with 0.3–0.6 meter per second canopy breeze and 20–40 full-room air exchanges per hour. Integrate biological controls like Bacillus subtilis or Bacillus amyloliquefaciens early, and consider sulfur vaporization pre-flower if appropriate in your IPM schedule. Stop all sulfur inputs by week two of flower to protect terpene integrity.
Irrigation frequency depends on media and root mass, but consistent 10–20% runoff in coco helps avoid salt accumulation. Automated drip systems with pulse irrigation (small, frequent feeds) stabilize root zone EC and reduce stress. In soil, allow the top 2–3 centimeters to dry between waterings while keeping the core moist to encourage healthy oxygen exchange. Maintain dissolved oxygen in hydro reservoirs at 7–9 mg/L using active aeration and 18–20°C solution temperatures.
Outdoor and greenhouse cultivation benefit from the strain’s compact form but require vigilance in late-season humidity. In temperate climates, expect harvest from early to mid-October at latitudes 40–45°N, depending on phenotype and weather. Plant spacing of 1.0–1.5 meters with aggressive trellising keeps colas upright and reduces mold risk. Foliar calcium and silica through mid flower can enhance cell wall strength against wind and pests.
Yield potential is strong for a compact plant, with 450–600 grams per square meter common in optimized indoor SCROG setups. Per-plant yields of 80–150 grams are typical in small tents with modest training and 250–350 watts per square meter of LED lighting. Hash makers often prioritize resin over raw weight, where Alien Blackout’s wash yields of 3–5% fresh frozen can be achieved on dialed-in phenos. Rosin producers report flower rosin returns in the 18–24% range with proper harvest timing and cure.
Harvest timing for flower typically targets a trichome mix of 5–10% amber, 70–80% cloudy, and the remainder clear for a balanced sedative profile. Pulling earlier (mostly cloudy) offers a slightly lighter head feel at the cost of some depth in body effect. Later pulls (15–25% amber) intensify sedation and can deepen couchlock for nighttime use. Always calibrate harvest to the intended experience and processing method.
Drying and curing are critical to preserving Alien Blackout’s dessert-and-spice personality. Aim for 10–14 days at 15–18°C and 58–62% RH with gentle, continuous airflow but no direct wind on buds. Post-dry, cure in airtight containers with daily burps for the first 7–10 days, then weekly for 4–6 weeks. Final jar water activity between 0.55 and 0.62 yields a resilient, terpene-rich finish with stable potency.
