Auto AnonyMASS is an autoflowering, mostly indica cannabis cultivar developed by Critical Mass Collective, a breeder known for pushing heavy-yielding, resinous lines. As an autoflower, it transitions from seed to harvest without a change in light cycle, making it accessible to newer growers and efficient for seasoned cultivators running perpetual gardens. The strain’s name signals both mass—reflected in dense, weighty colas—and a stealthy, low-fuss grow profile suited to compact spaces.
Indica-dominant autos are prized for their rapid lifecycle, manageable height, and relaxing effect profile. Auto AnonyMASS fits this mold, usually finishing in roughly 70–85 days from seed under optimized indoor conditions. Growers typically report a compact stature, thick lateral branching, and buds that stack early and hard, traits in line with Critical Mass Collective’s design goals.
Because it is an autoflower, the strain includes a proportion of Cannabis ruderalis genetics to trigger photoperiod independence. In practice, that means cultivators can keep lights at 18/6 or 20/4 from seed to harvest, simplifying scheduling. For consumers, the indica-heavy lineage generally translates to deep bodily calm, a grounded mood, and reliable nighttime suitability.
History of Auto AnonyMASS
Auto AnonyMASS emerges from Critical Mass Collective’s broader quest to modernize classic, heavy-yield indica expressions by engineering consistency, resin density, and robustness. While the exact release date is not centrally cataloged, the cultivar aligns with the 2015–2023 wave of autos that closed the potency gap with photoperiod strains. During this period, independent lab reports across the autoflower category began routinely logging THC values in the mid- to high-teens and beyond, a stark improvement over early 2010s autos.
Breeding programs like Critical Mass Collective’s commonly start with a proven photoperiod mother known for mass and a stable terpene signature, then integrate ruderalis to create an auto version. This process typically spans multiple filial generations to recapture parent potency and structure while fixing the auto trait. By the time a seed line is released commercially, breeders have usually stabilized flowering time and stature within relatively tight ranges, helping growers plan around predictable 10–12 week cycles.
The hallmark of the “Mass” family is weight: dense, golf-ball-to-cola-sized flowers that cure down with minimal loss in structure. An autoflower that can deliver mass without a long veg window is valuable to micro and commercial cultivators alike. Auto AnonyMASS reflects that calculus—speed, density, and resin—with a user-friendly growth curve that lowers the barrier to entry.
Genetic Lineage and Breeding Logic
Auto AnonyMASS is a mostly indica hybrid that incorporates ruderalis genetics to achieve autoflowering behavior. While breeders often keep exact parentage proprietary, the phenotype expresses traits consistent with Critical Mass-descended lines: tight internodes, thick calyx clusters, and a dominant myrcene-caryophyllene terp backbone. The ruderalis fraction in most modern autos typically settles around 10–30% after backcrossing, sufficient to lock in auto behavior while preserving the original chemotype.
Indica heritage tends to shape morphology and effect. Compact structure, broad-fingered leaves, and early bud initiation are common, with long pistil fields converging into solid top colas by the midpoint of bloom. On the user side, indica-heavy autos frequently skew toward body-centered relaxation, decreased sleep latency, and appetite stimulation, consistent with the expected cannabinoid-terpene ensemble.
Modern auto breeding practices use selection across multiple generations to recover potency after the initial ruderalis cross, a step that historically reduced THC. Over the last decade, autos have closed the gap; numerous indica-dominant autos now test from 17% to 22% THC in competent grows. Auto AnonyMASS sits squarely in this contemporary context, delivering potency and yield that compete with photoperiods in a shorter window.
Morphology and Appearance
Auto AnonyMASS typically reaches 60–110 cm indoors under 18/6 lighting, with phenotypic variation tied to pot size, light intensity, and root zone health. Plants develop a stout main stem and 6–10 strong laterals, with internodal spacing that favors stacked flower sites. The canopy leans conical when left untrained, but gentle low-stress training (LST) can spread tops to a uniform plane for more even light distribution.
Fans are broad and dark green, demonstrating indica dominance and robust chlorophyll content. As flowering progresses, sugar leaves frost rapidly, indicating strong trichome gland density even on peripheral tissue. Mature flowers display tightly packed calyces and a high calyx-to-leaf ratio that eases post-harvest trimming without sacrificing density.
Bud coloration ranges from lime to forest green with golden pistils that darken to orange-brown near maturity. In cooler night temperatures (18–20°C), some phenotypes can express faint purpling at the bract tips due to anthocyanin accumulation, though this is not universal. The final bag appeal is defined by glassy trichome heads and a near-spherical nug structure that compresses firmly without crumbling.
Aroma Profile
Aromatically, Auto AnonyMASS tends to present a sweet-critical foundation with layered earth, skunk, and citrus-peel top notes. Myrcene-forward cultivars commonly project ripe fruit and soft herbal warmth, while caryophyllene adds a peppery, resinous undertone. Limonene contributes a clean candied zest, rounding the profile into a balanced sweet-savory bouquet.
As plants mature, the intensity increases markedly, especially after week 6 of flower when monoterpene production peaks. In sealed curing jars, the scent sharpens for the first 7–10 days as chlorophyll dissipates and volatiles equilibrate. Expect medium to high pungency at grind, revealing deeper notes of hash, cedar, and faint floral sweetness consistent with linalool traces in some phenos.
Flavor and Consumption Experience
On inhalation, Auto AnonyMASS typically delivers a sweet, lightly creamy entry with a quick bloom of citrus and herbal tea. Mid-palate, the profile turns earthier and more resinous, reflecting caryophyllene and humulene’s sesquiterpene character. The finish often brings soft pepper, a hint of pine, and an aftertaste reminiscent of honeyed malt.
Vaporization showcases the terpene stack best between 175–195°C. At around 180°C, limonene and myrcene express as bright citrus and ripe fruit; nudging toward 190–195°C deepens pepper-spice complexity from caryophyllene. Combustion preserves much of the sweetness but may mute citrus top notes if temperatures run hot.
Cannabinoid Profile and Potency
As a mostly indica modern auto, Auto AnonyMASS commonly falls into a THC window of approximately 17–22% when cultivated under strong LED lighting and dialed-in nutrition. Less optimized setups still tend to produce mid-teens potency, reflecting improved auto breeding standards over the past decade. CBD is generally low, around 0.1–0.8%, with minor cannabinoids such as CBG measured in the 0.1–0.5% range in comparable indica autos.
Total cannabinoids often surpass 18–23% in well-grown samples, especially where post-harvest handling preserves trichome heads. Potency can fluctuate by 15–25% based on factors such as PPFD, harvest timing, and dry/cure conditions. For example, harvesting at 5–10% amber trichomes typically yields a balanced psychoactive arc, while waiting for 15%+ amber may slightly reduce perceived intensity but increase body heaviness.
For dosing, inexperienced users often find 2.5–5 mg THC sufficient for evening relaxation, while more tolerant consumers may prefer 10–20 mg via inhalation over a session. In flower form, a typical 0.25 g inhalation session of 18% THC flower delivers roughly 45 mg total THC, though actual uptake varies widely. Titration is recommended to avoid overshooting comfort, especially with indica-heavy chemotypes.
Terpene Profile and Aromachemistry
Auto AnonyMASS generally expresses a myrcene-dominant terpene profile supported by β-caryophyllene and limonene, with humulene and linalool as common minors. In many indica-leaning autos, total terpene content falls around 1.5–3.0% by weight when grown under optimized conditions. Within that, myrcene can range near 0.6–1.5%, β-caryophyllene around 0.3–0.9%, and limonene approximately 0.2–0.7%.
Myrcene contributes to the cultivar’s rounded fruit-herbal core and is frequently associated with perceived sedation in indica chemovars. Caryophyllene, a dietary cannabinoid that binds to CB2 receptors, adds peppery resin notes and may confer anti-inflammatory activity in preclinical models. Limonene’s bright citrus cut can uplift mood and sharpen the aroma, especially when buds are broken apart.
Secondary terpenes such as humulene (0.1–0.4%) and linalool (0.05–0.2%) can add woody dryness and faint floral hints. Terp expression is highly environment-dependent; excess heat above 26–27°C in late flower can volatilize monoterpenes and reduce measured totals by double-digit percentages. Gentle drying at 50–60% RH and 18–21°C helps preserve delicate fractions for a fuller sensory experience.
Experiential Effects and User Reports
The experiential arc of Auto AnonyMASS typically begins with a gentle headcalm followed by a progressive body melt over 20–40 minutes. Users often report muscle relaxation, reduced mental chatter, and a subtle mood boost rather than racy euphoria. Peak effects commonly persist 60–120 minutes for inhalation, with a residual tranquil afterglow.
Because of its indica weight, the strain is widely chosen for evening sessions, wind-down routines, and screen-time relaxation. Appetite stimulation is frequently noted, especially at higher doses. At conservative doses, users describe functional calm suitable for light conversation, music, or passive media, while larger intakes tend toward couchlock and sleep.
Potential adverse effects mirror the broader THC category. Dry mouth occurs in roughly 30–35% of consumers and dry eyes in about 20–25%, based on aggregate user surveys across indica-dominant strains. Transient anxiety or dizziness appear less commonly with indica autos than with high-limonene sativas, but sensitive individuals should start low and go slow.
Potential Medical Applications
Auto AnonyMASS’s indica-forward profile makes it a candidate for addressing sleep latency and sleep maintenance, with many patients favoring evening use. In patient reports, inhaled THC of 5–10 mg within 30–60 minutes of bedtime can materially shorten time-to-sleep; combining with linalool- and myrcene-rich cultivars may deepen sedation. For those with daytime fatigue, microdosing (1–2 mg THC) can provide calm without heavy impairment.
Chronic and neuropathic pain sufferers often gravitate to caryophyllene-rich indica chemotypes for body relief. β-Caryophyllene’s CB2 affinity, while not a cure-all, aligns with anti-inflammatory goals in preclinical literature. Users commonly report moderate reductions in perceived pain intensity and muscle tension, especially when dosing is paired with heat therapy or gentle stretching.
Anxiety relief is more variable. Some individuals find the grounded, myrcene-heavy profile reduces rumination, while others may experience sedation that feels demotivating. As with all THC-dominant strains, those with a history of psychosis, uncontrolled cardiovascular conditions, or panic disorder should consult a clinician and approach cautiously.
Cultivation Guide: Indoors and Controlled Environments
Lifecycle and scheduling: Most Auto AnonyMASS phenotypes finish in 70–85 days from seed under stable conditions. Plan for 10–14 days seedling, weeks 3–5 early vegetative and preflower stretch, weeks 6–10 bulk and ripening. Because autos flower on age, minimize stress during days 10–28 to avoid stunting.
Lighting: Maintain an 18/6 or 20/4 photoperiod from seed to harvest; both work well, with 18/6 providing excellent results and lower power use. Target PPFD around 300–400 µmol/m²/s for seedlings, 500–700 in vegetative, and 700–900 in bloom. Aim for a daily light integral (DLI) of ~20–25 mol/m²/day in early veg and 35–45 mol/m²/day in flower; higher PPFD requires adequate CO2 and nutrition.
Environment: Keep temps 24–26°C in veg and 22–24°C in flower, with a 2–4°C night drop. Relative humidity should be 65–70% seedling, 55–60% veg, and 40–50% in flower; late bloom can be held near 45% to deter Botrytis. Track VPD near 0.8–1.1 kPa in veg and 1.2–1.5 kPa in flower for optimal gas exchange.
Medium and pH: In coco/perlite (70/30), maintain pH at 5.8–6.2 and feed daily to 10–20% runoff. In soil, use a light, well-aerated mix and water to 5–10% runoff, holding pH 6.2–6.8. Autos prefer consistent moisture—avoid both saturation and drought; allow the top 2–3 cm to dry before re-watering.
Nutrition and EC: Autos are sensitive to excess nitrogen in early flower. Use EC 0.8–1.2 in seedling, 1.2–1.6 veg, 1.6–1.9 early flower, and 1.8–2.1 peak bloom, adjusting to leaf color and runoff readings. Typical NPK ratios trend to higher N in veg (e.g., 3-1-2) and higher P/K in bloom (e.g., 1-2-3), with supplemental Ca/Mg at 100–150 ppm Ca and 50–75 ppm Mg in coco.
Plant training: Start gentle LST around day 18–25, guiding the main stem laterally to expose secondary sites. Many growers avoid topping autos; if used, top once at node 4–5 before day 21 to minimize stall risk. Defoliation should be conservative—remove only leaves that block prime bud sites, and avoid heavy strips after day 35.
Pot sizing and root management: Start autos in their final container to prevent transplant shock. Use 11–19 L (3–5 gal) fabric pots for a balance of root volume and speed; larger pots can extend the cycle slightly. Maintain strong root-zone oxygenation with good aeration and avoid overwatering, which can suppress growth rates by 10–30%.
CO2 and airflow: Enriching to 800–1,100 ppm CO2 lets you push PPFD to 900–1,050 µmol/m²/s, provided nutrition keeps pace. Ensure brisk, non-turbulent air movement above and below the canopy to reduce microclimates; a total room air exchange of at least 20–30 air changes per hour is typical in small tents. Canopy temperatures should be monitored with an IR thermometer to ensure leaf surface stays within 1–2°C of room ambient under LEDs.
IPM and disease prevention: Dense indica autos can be Botrytis-prone late in flower. Maintain RH under 50% from week 6 onward, prune inner fluff, and ensure adequate spacing. Sticky cards, periodic inspections, and biologicals like Bacillus thuringiensis (for caterpillars) and predatory mites (for mites/thrips) help keep pests below threshold without harsh sprays.
Watering cadence example: In coco, a 4-gallon fabric pot may take 1.0–1.5 L per watering in early veg, rising to 1.5–2.2 L in peak bloom, typically daily or twice daily under high PPFD. In soil, water every 2–4 days depending on pot size and environment, targeting 10% runoff. Weight-of-pot and moisture meters reduce guesswork and mitigate overwatering risk.
Troubleshooting: Pale new growth with interveinal yellowing often signals Mg deficiency under strong LED; add 0.5–1.0 ml/L Cal-Mag or raise Mg by 30–50 ppm. Dark, clawed leaves in early bloom suggest N excess—reduce N by 15–25% and monitor runoff EC. If stretch exceeds expectations, increase blue spectrum proportion slightly and reduce canopy distance without exceeding PPFD limits.
Cultivation Guide: Outdoor and Greenhouse Strategies
Outdoors, Auto AnonyMASS thrives in temperate-to-warm climates, where a 10–12 week seed-to-harvest rhythm enables multiple cycles per season. Optimal average daytime temperatures range from 22–28°C with nighttime above 12°C to avoid growth slowdown. In cooler regions, greenhouses extend the season and protect against wind and precipitation that can damage dense colas.
Choose containers of 19–27 L outdoors to balance moisture retention and oxygenation, or plant directly in amended beds with high organic matter. Space plants at least 60–90 cm apart for airflow. Mulch with 2–5 cm of straw or bark to stabilize root-zone temperatures and reduce irrigation frequency by 15–30%.
Feeding outdoors can be achieved with slow-release organics or periodic fertigation. Maintain soil pH around 6.3–6.7 and deliver supplemental K and Ca in early bloom to fortify cell walls and reduce bud rot risk. If rainfall is frequent, erect a simple rain cover during the last 2–3 weeks to protect the ripening canopy.
Pest management emphasizes prevention: deploy yellow and blue sticky traps, inspect undersides of leaves weekly, and encourage beneficials with companion plants like dill and marigold. For caterpillars, weekly BT sprays in early flower are effective; discontinue sprays by mid flower to preserve resin quality. Avoid oil-based foliar products in bloom, which can damage trichomes and elevate mold risk.
Harvest, Drying, and Curing
Timing harvest on autos requires trichome and pistil checks rather than calendar dates. For a balanced effect, many growers target mostly cloudy trichomes with 5–10% amber; for a heavier body feel, 10–15% amber is common. Pistils should be mostly brown/orange and receded, with visible calyx swelling over the prior 7–10 days.
Pre-harvest practices vary; some cultivators reduce nitrogen in the final 10–14 days to improve burn quality, while others maintain full nutrition until the end. A brief dark period of 24–36 hours before chop is sometimes used anecdotally, though measurable terpene differences are inconsistent. The most reliable quality bump comes from a meticulous dry instead of pre-harvest rituals.
Dry in 18–21°C and 50–60% RH with gentle airflow for 10–14 days. Target a slow dry that brings small stems to a near-snap and large stems to a bend without stringiness, typically when flowers reach 10–12% internal moisture. Overly fast drying can reduce terpene totals and increase perceived harshness.
Cure in airtight containers at 62% RH, burping daily for the first week and then weekly for 4–8 weeks. During cure, chlorophyll byproducts off-gas and the flavor consolidates, often increasing smoothness by a noticeable margin. A properly cured batch frequently shows a 10–20% improvement in perceived aroma intensity compared to a rushed cure.
Yield Expectations and Performance Metrics
Indoors, Auto AnonyMASS commonly yields 400–550 g/m² under efficient full-spectrum LEDs when grown in 3–5 gallon fabric pots and properly trained. Skilled growers with CO2, dialed PPFD, and high-frequency fertigation can push beyond 600 g/m², though such results rely on precise environment and agronomy. Single-plant yields in 11–19 L containers typically range from 60–150 g per plant depending on pot size, light, and cycle length.
Outdoors, expect 50–150 g per plant in mid-latitude summers, with larger containers and full-sun exposure pushing the higher end. Greenhouse conditions can increase yield by 10–25% versus open field due to microclimate control and reduced weather stress. Dense bud architecture means meticulous humidity control is necessary in the final weeks to avoid losses to bud rot.
Efficiency metrics such as grams per watt (g/W) provide a clear benchmark. Well-tuned indoor grows of indica autos often achieve 1.2–1.8 g/W under LED; top-tier rooms with CO2 and aggressive PPFD may exceed 2.0 g/W. For many growers, the consistent 70–85 day turnaround is as valuable as raw yield, enabling 4–5 harvests per year in the same space without complex light scheduling.
