Auto Demon Mass is a mostly sativa autoflower created by Mr. Hide Seeds, a breeder known for vigorous, high-resin automatic genetics. As an autoflower, it initiates bloom by age rather than day length, allowing reliable harvests in 9 to 12 weeks from sprout under stable indoor conditions. The sativa lean gives it an energetic, bright personality, while the autoflower architecture keeps plants compact enough for modest spaces.
Growers value Auto Demon Mass for its ratio of speed to output, a balance that has defined the modern autoflower renaissance. Under competent lighting and nutrition, indoor harvests commonly reach into the mid range for autos, while outdoor growers can stage multiple runs per season in temperate climates. The strain aims to deliver a layered sensory profile and a clear, motivational effect that suits daytime use for many consumers.
Contemporary seed marketplaces have reshaped expectations for autos, highlighting production and complexity once reserved for photoperiod lines. Seed retailers have noted in descriptions of benchmark autos such as Northern Lights Autoflower that modern automatic varieties can produce very well and carry complex aroma and flavor. Auto Demon Mass fits within this new generation, pairing fast finishing times with quality that stands up to daily use and careful connoisseur scrutiny.
History and Breeding Background
Mr. Hide Seeds developed Auto Demon Mass to capture the quick-turn advantage of autoflowering genetics without sacrificing the zesty lift of a sativa. The breeder’s catalog has long leaned into vigorous autos that finish reliably across environments, a hallmark of Cannabis ruderalis integration done well. While the exact parental pairing has not been formally published, the name cues an emphasis on density and weight, paired with an assertive, energetic profile.
The broader history of autoflowers traces to early 2000s work stabilizing the day-neutral trait from ruderalis into high-THC lines. First-generation autos often yielded modestly and presented simpler aromas, but each breeding cycle improved resin output, terpene richness, and plant structure. By the early 2020s, well-run auto rooms commonly achieved 400 to 600 grams per square meter with potency reaching into the high teens and low 20s for THC.
Market behavior supports this performance arc. Retailers with extensive catalogs report strong demand growth for autos due to predictable schedules and the ability to harvest multiple times per season outdoors at higher latitudes. The presence of high-profile autos with positive performance notes, such as those describing Northern Lights Autoflower as producing very well with complex flavor, illustrates how much the category has matured.
Auto Demon Mass emerged as part of this matured wave, tuned for compact vigor and a sativa-forward experience. The breeding goal seems clear: deliver a fast, high-energy cultivar with enough terpene detail to satisfy flavor-driven consumers. The result is a cultivar positioned as a workhorse for small tents and a sprint runner for outdoor windows in short summers.
Genetic Lineage and Autoflowering Trait
What is known with confidence is that Auto Demon Mass inherits the autoflowering trait from a ruderalis line integrated into a sativa-dominant backbone. Autoflowering results from age-dependent flowering pathways that bypass photoperiod triggers, allowing the plant to transition to bloom after several weeks regardless of day length. Breeders stabilize this trait over multiple filial generations while selecting for resin production, branching, and flavor richness.
The second component is the sativa-leaning ancestry that shapes the strain’s effect profile and architecture. Sativa-leaning autos often exhibit slightly taller internodes, airier flower stacking, and terpene sets anchored by terpinolene, ocimene, or limonene. Auto Demon Mass appears to conform to this pattern, showing a strong mid-stretch and a high calyx-to-leaf ratio when managed with gentle training.
The Mass element in the name hints at density breeding targets sometimes associated across the market with Critical Mass descendants. However, Mr. Hide Seeds has not publicly released a confirmed photoperiod parentage for Auto Demon Mass, and any direct tie should be treated as speculative. What is consistent is the selection for volumetric yield in a fast, day-neutral chassis.
Taken together, you can expect the genetics to deliver time-to-harvest reliability, sativa-forward uplift, and improved autoscale yield. This synthesis mirrors the broader trend in modern autos, which compresses grow cycles while retaining more of the sensory and effect nuance once reserved for photoperiods. The result is a plant that checks both production and quality boxes for diverse growers.
Plant Morphology and Appearance
Auto Demon Mass typically presents a medium height profile for an auto, with indoor plants finishing around 70 to 110 centimeters and outdoor plants ranging from 80 to 130 centimeters depending on root volume and light intensity. The architecture leans apical, though lateral branching fills in predictably when topped early or guided with low-stress training. Internodal spacing is moderate, allowing light to penetrate and fatten mid-canopy flowers.
The flowers are conical with a high calyx-to-leaf ratio, which helps trimming efficiency and jar appeal. Sativa influence tends to add fine pistils that shift from white to orange and amber as maturity approaches. Trichome coverage is abundant by late bloom, leaving a frosty finish that looks impressive even before a proper cure.
Color expression is generally lime to forest green in the bracts, with occasional dusk tones if night temperatures drop by 5 to 8 degrees Celsius late in flower. Sugar leaves remain slender and can show a slight curl inward as resin peaks. A well-grown specimen looks clean, symmetrical, and built for airflow, resisting botrytis better than denser indica-leaning autos.
Aroma Bouquet
The aroma opens bright and clean, hinting at citrus peel, green mango, and cut herbs. As flowers ripen, the bouquet deepens with layers of sweet spice and a light pine snap that lands somewhere between rosemary and cedar. The top note reads as daytime fresh rather than dessert-sweet, telegraphing the sativa heritage.
Breaking a cured bud intensifies a zingy terpene lift often associated with terpinolene and limonene. Sweet-bitter citrus mixes with soft floral volatiles, while a peppery edge from caryophyllene anchors the base. The overall impression is complex without being cloying, rewarding a slow nose-in after the jar is cracked.
During grinding, expect aromatics to bloom rapidly, sometimes outpacing the room’s ventilation if you are in a small space. Hints of tropical fruit and pear can emerge briefly, then resolve into herbal spice. The balance of sweet, tart, and savory notes makes the strain versatile for both joints and vaporizers.
Flavor Profile
Auto Demon Mass carries its perfume into the palate with a zesty, mouthwatering onset. The first impression is citrus-forward, often evoking tangerine, grapefruit pith, and a pinch of lime zest. A second wave brings sap-like pine and green herbal tones, refreshed by a faint floral lift.
On the exhale, peppery spice peeks through and mingles with a light sweetness, smoothing the finish. Vaporization at lower temperatures around 175 to 185 degrees Celsius emphasizes citrus and floral high notes, while combustion brings out the woody spice and a gentle resin warmth. The aftertaste lingers as clean, slightly sweet citrus with a dry-herb echo.
The flavor complexity is notable for an automatic, mirroring the broader trend in modern autos. Retailer notes for benchmark autos like Northern Lights Autoflower highlight how contemporary autos can produce very well and deliver complex flavor, countering older assumptions. Auto Demon Mass sits comfortably in this mold, offering a bright and layered profile suited to daytime sessions.
Cannabinoid Profile and Potency
As with many breeder releases where formal lab sheets are not widely published, precise cannabinoid values for Auto Demon Mass vary by phenotype and cultivation. In the modern autoflower segment, THC commonly spans 16 to 24 percent by dry weight when grown under high-intensity lighting with optimal nutrition. CBD in sativa-leaning autos usually remains low, often at or below 1 percent, with trace minors such as CBG in the 0.2 to 1.0 percent range.
Users report a fast-acting cerebral lift consistent with mid-to-high THC autos, with a clear ceiling set by individual tolerance and dose. Vaporized flower tends to feel cleaner and slightly more head-forward, while combusted flower can seem warmer and more body-inclusive due to higher temperature decarboxylation. Expect onset in 2 to 10 minutes by inhalation, with peak effects around 30 to 45 minutes and a 2 to 3 hour total duration.
Where available, home test kits and dispensary-adjacent analytics frequently find total cannabinoids for productive autos in the 18 to 26 percent band. Environmental variables account for much of the swing, including photosynthetic photon flux density, root-zone EC stability, and leaf surface temperature. Consistency improves markedly when PPFD is held around 700 to 900 µmol per square meter per second in bloom with a daily light integral tuned for autos.
Terpene Profile and Aromachemistry
The terpene ensemble of Auto Demon Mass reads sativa-forward, with terpinolene, limonene, and beta-caryophyllene commonly implicated by the aroma and flavor. In modern autos, total terpene content often falls between 1.0 and 2.5 percent of dried flower mass when cured well. Within that total, terpinolene-dominant expressions can occupy 0.2 to 0.6 percent, limonene 0.2 to 0.5 percent, and caryophyllene 0.1 to 0.4 percent, depending on phenotype and grow.
Terpinolene imparts the fresh citrus-floral top note with a hint of pine and apple peel. Limonene contours the bright citrus zest and can contribute to mood elevation in user reports. Beta-caryophyllene offers a peppered, woody base that interacts with cannabinoid signaling via CB2 receptor affinity, making it a unique dietary terpene with potential anti-inflammatory properties.
Secondary terpenes such as ocimene, alpha-pinene, and linalool appear to round out the profile. Ocimene can deliver green fruit and floral sweetness, while pinene adds coniferous clarity and linalool provides a soft lavender cushion. The balance of these volatiles explains why the strain tastes clean and leaves an uncloying aftertaste.
From a practical standpoint, preserving this terpene content depends on careful post-harvest handling. Keeping dry room temperatures near 18 to 21 degrees Celsius and relative humidity at 55 to 60 percent limits volatilization losses. A gentle cure of 3 to 8 weeks with minimal jar burping after the first 10 days helps terpenes polymerize into a coherent bouquet.
Experiential Effects and Usability
Auto Demon Mass leans stimulating and upbeat, offering a mental lift that many users describe as clear and purposeful. Early effects include increased alertness, brighter mood, and a subtle pressure behind the eyes that settles into a flow state. Music, light creative work, and socializing tend to be enhanced without overwhelming introspection at moderate doses.
The body feel is present but secondary, showing as a buoyant comfort rather than heavy relaxation. As dose increases, a warm, spicy body tone emerges with mild muscle ease and appetite stimulation. Some users may note an edge of racy energy if sensitivity to sativa-leaning terpenes is high, so pacing is advised.
Measured inhalation helps manage intensity. A single joint shared among two to three people or a few moderate vapor pulls often hits the sweet spot for daytime function. Heavier consumption can blur the line into couch time, especially if combined with caloric meals or alcohol.
Functional windows are typically 90 to 150 minutes before a gentle taper into normal baseline. For evening use, pairing with a more sedative cultivar can produce a balanced entourage. The strain’s clean finish and low residual grogginess make it a practical companion for errands, hikes, or studio sessions.
Potential Medical Applications
While formal clinical data on this specific cultivar are limited, its sativa-forward profile suggests several potential wellness applications. Mood elevation and perceived energy increases make it a candidate for addressing mild situational depression and fatigue. Users often report improved focus and task engagement at low to moderate doses, which some find helpful for attention-related concerns.
The presence of beta-caryophyllene and limonene aligns with anti-inflammatory and anxiolytic potential in preclinical and nutritional studies. Mild analgesic effects can arise from a combination of THC-mediated central modulation and caryophyllene’s peripheral CB2 activity. Headache relief and tension release are commonly reported subjective outcomes in this chemotype.
Appetite stimulation is modest to moderate and can be beneficial for those experiencing reduced hunger from stress or medication side effects. Nausea control may also be supported due to THC’s well-documented antiemetic properties. However, the energizing nature means it may not suit those with anxiety-prone physiology; slow titration is important.
As always, individual responses vary, and medical decisions should involve a healthcare professional. Vaporization at lower temperatures may yield clearer headspace for daytime therapeutic use. Patients sensitive to stimulation can consider microdoses, such as a single small vapor draw every 60 to 90 minutes, to gauge response without overshooting.
Comprehensive Cultivation Guide
Auto Demon Mass rewards precise, low-stress cultivation. The entire cycle typically spans 70 to 95 days from sprout under indoor conditions, with environmental stability playing the largest role in finishing speed. Because autos cannot recover time lost to severe stress, a smooth run matters more than maximal interventions.
Germination can be done via paper towel or direct sow into the final container to avoid transplant shock. If starting in plugs, transplant by day 7 to 10 at the latest, before roots circle. Maintain seedling temperatures at 23 to 26 degrees Celsius and relative humidity at 65 to 75 percent for rapid establishment.
Container size influences plant size and yield. For indoor grows, 11 to 15 liter fabric pots provide a good balance of vigor and watering frequency; outdoors, 20 to 30 liters scale tops and lateral branching. High-porosity media such as 30 percent perlite in coco or a light, aerated organic mix helps autos feed efficiently without waterlogging.
Lighting drives output. In veg and early stretch, target 500 to 650 µmol per square meter per second PPFD, rising to 700 to 900 PPFD in bloom. Many growers run autos at 18 hours on and 6 hours off throughout, though 20 on and 4 off can increase daily light integral by about 11 percent if heat is controlled.
Nutrition should start gently and scale with demand. In coco, begin at 0.8 to 1.2 EC during week 1 to 2, ramp to 1.6 to 1.9 EC through peak bloom, and taper to 1.2 near harvest. In living soil, top-dressings at days 14, 28, and 42 with balanced dry amendments and supplemental calcium and magnesium usually suffice.
Maintain pH at 5.7 to 6.1 in hydroponic or coco systems and 6.3 to 6.8 in soil. Adequate calcium and magnesium are critical under LED lighting, which increases leaf surface transpiration efficiency and can reveal latent deficiencies. Supplement 100 to 150 ppm Ca and 50 to 75 ppm Mg as needed when leaves show interveinal chlorosis or tip curl under high PPFD.
Air and climate steer morphology. Keep day temperatures at 24 to 28 degrees Celsius and nights 3 to 6 degrees cooler to maintain metabolic pace without stressing stomata. Relative humidity should track VPD around 0.8 to 1.2 kPa in veg and 1.2 to 1.6 kPa in bloom, translating roughly to 60 to 70 percent RH early and 45 to 55 percent late.
Training should be minimal and timed carefully. If topping, do it once between day 14 and 18 at the 4th to 5th node, then pivot to low-stress training to open the canopy. Aggressive defoliation can stall autos; instead, remove only leaves that shade flowering sites or impede airflow, roughly 10 to 15 percent of foliage at a time.
Watering cadence matters. In fabric pots, water to about 10 to 15 percent runoff when the top 2 to 3 centimeters of media are dry, typically every 1 to 2 days in mid-cycle. Overwatering early is a common yield killer, so allow a light dryback to encourage root exploration.
CO2 enrichment can boost final weight if light and nutrition are already optimal. At 900 to 1000 PPFD, supplementing CO2 to 900 to 1100 ppm can accelerate photosynthesis and tighten internodal spacing. Ensure canopy temperatures are 1 to 2 degrees higher under CO2 to keep stomatal conductance aligned with gas exchange.
Pest and pathogen prevention is easier than cure. Start clean, avoid overcrowding, and keep leaves dry during the dark period to reduce botrytis risk. Sticky traps and weekly canopy inspections catch fungus gnats, thrips, or mites before they spread; biological controls such as Bacillus thuringiensis israelensis for gnats and Amblyseius swirskii for thrips can be integrated early.
The stretch window for a sativa-leaning auto like Auto Demon Mass usually falls between days 18 and 32. During this phase, nitrogen demand remains moderate, while phosphorus and potassium uptake increase. A bloom booster at a modest rate can support flower initiation, but avoid spiking EC more than 0.2 to 0.3 at once.
By mid-bloom, flowers stack with a glossy resin sheen. Keep air movement constant with mixed vertical and horizontal fans to prevent microclimates. Removing the lowest 10 to 20 percent of inner growth by day 30 improves airflow and directs energy to productive sites.
Expect initial harvest windows between days 70 and 85 for most phenotypes, with some running to day 95 in cooler rooms or under conservative feeding. Track maturity using trichome color on calyxes rather than sugar leaves. A common target for an energetic effect is roughly 5 to 10 percent amber trichomes, 70 to 80 percent cloudy, and the remainder clear.
Indoor yields of 400 to 550 grams per square meter are attainable with 700 to 900 PPFD, proper VPD, and steady feed, while single plants can produce 60 to 150 grams depending on pot size and training. Outdoor plants in 20 liter containers often land in the 70 to 180 gram range under full sun with 12 to 14 hours of daily light mid-season. These outputs align with the modern auto cohort that has reset expectations around speed and production.
Pre-harvest practices can tune the finish. A 7 to 10 day nutrient taper prevents harsh mineral buildup, and some growers use a final 36 hours of darkness to prompt resin swelling, though data on this is largely anecdotal. Keep root zones moist but not saturated to avoid late-stage root issues that can collapse terpenes.
Drying and curing determine how much of the aroma survives into the jar. Aim for 18 to 21 degrees Celsius and 55 to 60 percent relative humidity with sub-0.3 meters per second gentle airflow, targeting 10 to 14 days dry time if branches allow a slow, even desiccation. Expect about 70 to 75 percent weight loss from wet to dry flower.
Once jarred, maintain 58 to 62 percent internal humidity for a clean, springy feel and steady terpene expression. Burp jars daily during the first week, then every few days for the second; after day 14, opening only once a week supports terpene stabilization. Many auto cultivars, including this one, show their best flavor between weeks 3 and 6 of cure, with additional smoothness appearing by week 8.
Taken together, a low-stress, high-consistency approach extracts the most from Auto Demon Mass. The cultivar thrives in environments that value rhythm over aggressive manipulation. Growers who maintain stable PPFD, VPD, and EC from week to week tend to pull the most attractive and flavorful flowers on a reliable schedule.
