Auto Douce Nuit is an autoflowering cannabis variety developed by French Touch Seeds, a breeder known for preserving European heirlooms and crafting practical, grower-friendly lines. The name translates to Sweet Night, which hints at its intended role as a calming, evening companion. As an autoflower, it transitions to bloom on its own schedule, independent of light cycle, thanks to its ruderalis heritage. This makes it suitable for both novice growers looking for simplicity and experienced cultivators seeking fast, discreet harvests.
The strain’s genetic base is a three-way foundation of ruderalis, indica, and sativa, aiming to balance a steady body relaxation with a clear, friendly headspace. French Touch Seeds has historically favored robust, field-ready genetics, and Auto Douce Nuit fits that brief with compact structure and dependable finishing times. While official, fully published lab results for this specific variety are limited, it shares the modern auto category’s common performance envelope. That means competitive potency, terpene expression above the old auto baseline, and lifecycles that can finish in under three months from seed.
Auto Douce Nuit is cataloged by third-party databases in the cannabis space, including listings found via sitemap indexes such as CannaConnection, underscoring its recognition by the wider community. These listings typically mirror the breeder’s positioning: autoflower convenience with hybrid appeal and broad environmental adaptability. In practice, most growers deploy it for relaxed nighttime sessions, quick personal harvests, and compact indoor runs. Its forgiving nature also makes it a reasonable first auto for cultivators transitioning from photoperiod strains.
Because autoflower genetics lock in a narrow veg window, success with Auto Douce Nuit relies more on early plant health and consistent environment than on heavy training. When provided the right conditions—moderate feeding, ample light, and stable climate—plants tend to produce dense, resin-coated colas with a sweet-herbal bouquet. The result is a strain that punches above its size class in efficiency and ease of use. For home gardeners, its speed-to-jar and manageable stature are often the decisive advantages.
History and Breeding Background
French Touch Seeds emerged with an ethos rooted in European cannabis culture, emphasizing functional, reliable plants that respect traditional profiles while embracing modern breeding. Auto Douce Nuit reflects that philosophy, translating a soothing nighttime character into an autoflowering format. While the breeder has not publicly disclosed the exact parent lines, the project likely involved crossing a selected photoperiod mother with a stabilized ruderalis donor, followed by several filial generations to lock the auto trait. This process typically takes multiple cycles of selection to harmonize potency, flavor, and the autoflower trigger.
Autoflowering cannabis traces back to Cannabis ruderalis populations native to higher-latitude regions, where day length changes rapidly and summers are short. Breeders incorporate ruderalis to create plants that flower based on age rather than photoperiod, allowing 9–11 week seed-to-harvest runs in many cases. The trade-off historically was reduced potency and terpene complexity, but modern autos have largely overcome that gap. Reports from the 2018–2024 period show THC medians for advanced autos rising into the mid to high teens, with top performers surpassing 20%.
Auto Douce Nuit rides this wave of improvement by pairing the reliable finish and compact habit of ruderalis hybrids with an indica-leaning temperament. The goal is a calming body effect with a tempered, clear mental lift, suitable for evenings without forcing couchlock unless dose is high. Sativa influence is present but moderated, contributing to a friendly mood and a slightly broader sensory palette. Together, these elements place the strain in the modern auto sweet spot of accessibility and quality.
Within public-facing strain directories, including sitemap listings such as those crawled from CannaConnection, Auto Douce Nuit is referenced alongside the broader French Touch catalog. While these entries often keep lineage high level, they confirm a community footprint for the variety. For growers, that means peer experiences and grow logs exist, offering practical insights into feeding tolerance, height control, and finishing windows. Such community knowledge is particularly valuable for autos, where timing and restraint matter more than heavy plant manipulation.
Genetic Lineage and Inheritance
Auto Douce Nuit’s declared heritage is ruderalis, indica, and sativa, with ruderalis providing the autoflowering trigger. Indica contributions are responsible for the compact, stocky structure and the primary body ease many users report. Sativa inputs contribute to mental clarity, a lighter mood lift, and potentially a slightly broader terpene bouquet. The breeder has not disclosed the exact photoperiod parents, a common practice to protect IP in competitive markets.
In an autoflower, inheritance strategy often focuses first on stabilizing the auto trait, then backcrossing or selecting toward potency and flavor. A typical approach is to select F2 or F3 generations for uniform onset of flowering at 3–5 weeks from sprout, while also screening for resin density and bud formation. By F4 or F5, reliable autos generally exhibit consistent apical flower sets and predictable finishing windows, usually within a two-week spread. Auto Douce Nuit exhibits this kind of consistency, with most plants initiating flower on schedule even under 18–20 hours of light.
The indica dominance is observable in internodal spacing and leaf morphology. Expect medium-width leaflets, a moderate leaf-to-calyx ratio, and dense, weighty buds in later bloom. Sativa influence appears as a touch more stretch during early bloom and a livelier top-note in the aroma. Ruderalis inheritance shows in the plant’s compact height, hard-wired flowering schedule, and resilience to variable photoperiods.
Phenotypic spread in autos can be a bit wider than in inbred photoperiods, but modern lines like Auto Douce Nuit tend to present two main phenotypes: a shorter, stockier plant with pronounced indica expression, and a slightly taller sister with a modicum of extra stretch. The former often finishes on the earlier side of the window, while the latter may add 5–10 days in exchange for a touch more yield. Both fit comfortably in tent grows and guerrilla plots. For most home cultivators, the difference comes down to headroom and harvest timing rather than significant changes in potency.
Appearance and Morphology
Auto Douce Nuit typically grows to a final height of 60–100 cm indoors, with outliers in dialed environments occasionally reaching 110–120 cm. The structure is compact with a central cola and a ring of secondary tops, reflecting an indica-forward habit. Internodes are tight to medium, forming stacked flower sites that coalesce into dense, contiguous spears. Leaves are medium green and can darken slightly under cooler night temperatures late in bloom.
During preflower, most plants exhibit a short burst of vertical growth over 10–14 days, often doubling in height from the end of the seedling stage. Branches remain sturdy, and with adequate airflow, lateral sites develop into firm, golf-ball to soda-can sized buds. Trichome coverage becomes evident by week 4–5 from sprout, with noticeable frost encasing sugar leaves and calyces. By maturity, resin coverage is visually prominent, and sugar leaves often curl inward toward swollen calyx clusters.
Bud morphology skews toward dense, resinous nugs with a medium calyx-to-leaf ratio. Pistils begin cream to light peach and mature to amber-orange hues, contrasting against a forest-to-olive green backdrop. Under strong LED lighting, anthocyanin expression can appear in some phenotypes as faint purple tinges, especially when night temperatures drop 2–4°C below day temps. Overall bag appeal is solid for an auto, with crystals readily visible and a tidy trim profile.
Stems are proportionally thick for the plant’s size, aiding in support without extensive staking. That said, cola weight in late flower may require a few soft ties or bamboo stakes, particularly in high-yield scenarios. The plant’s compact geometry also lends itself to canopy uniformity in small tents. With minimal training, it produces a symmetrical, practical structure that is easy to manage.
Aroma and Flavor Profile
Growers commonly report a sweet-herbal aroma from Auto Douce Nuit, consistent with its name and evening-leaning character. The scent opens with gentle floral sweetness reminiscent of wildflower honey, layered over fresh herbs. Earthy undertones and a hint of wood or cedar provide grounding depth. On a warm dry pull, some phenotypes add a faint lavender-like calm or soft spice.
As flowers mature, volatile terpenes intensify, especially after a proper cure of 3–6 weeks. The initial nose when a jar is cracked often blends sweet pastry notes with a light pepper tickle, suggesting the interplay of myrcene and beta-caryophyllene. Limonene and linalool can add citrus-lilac accents that feel clean yet soothing. In well-cured samples, a subtle vanilla-fudge sensation sometimes emerges at the tail end of the exhale.
Flavor tracks closely with aroma but leans slightly earthier on combustion or vaporization. Expect a sweet front palate, an herbal middle, and a peppered finish that lingers gently without harshness when cured correctly at roughly 60% relative humidity. Vaporization at 180–190°C tends to highlight floral and citrus top notes, while combustion tilts toward wood and spice. Terpene preservation improves with slow drying and glass curing, and many users report a marked flavor lift between week two and week four of cure.
The overall profile is approachable and not overpowering, making it suitable for shared sessions and sensitive palates. It is fragrant enough to be satisfying, yet it does not scream across the room like some ultra-loud cultivars. For discretion, a carbon filter will suffice indoors, as the scent, while pleasant, becomes more pronounced in the final two weeks of bloom. In portable use, its sweetness reads as inviting rather than skunky-pungent.
Cannabinoid Profile and Potency
Autoflowering strains have seen a marked rise in potency over the past decade, and Auto Douce Nuit aligns with that trend. In the modern auto category, published lab data for similar indica-leaning autos commonly show THC ranges of 14–20%, with elite phenotypes surpassing 20% under optimal conditions. CBD is typically low in these profiles, often 0.1–1.0%, unless specifically bred for cannabidiol. Minor cannabinoids like CBG may register in the 0.3–1.0% bracket, though expression varies with environment and phenotype.
Grow conditions significantly influence potency. Light intensity correlates with cannabinoid accumulation; indoors, a PPFD of 700–900 µmol/m²/s during peak bloom can support robust THC development if other variables are balanced. Nutrient management that avoids nitrogen toxicity in late flower helps terpene and cannabinoid expression, with many growers stepping down N by 25–40% from mid bloom onward. Temperature and RH stability reduce plant stress, which in turn supports steady resin production.
Delivery method also affects perceived potency. Inhalation onset typically arrives in 2–5 minutes, with peak effects at 30–60 minutes and a 2–4 hour duration for most users. Vaporization often feels cleaner and may preserve terpenes that modulate subjective intensity through entourage effects. Edible preparations can deliver longer, broader effects, with onset at 45–120 minutes and a 4–8 hour duration depending on dose and metabolism.
While exact lab numbers for Auto Douce Nuit can vary by seed lot and test site, user reports place it squarely in the competent modern auto tier. In practical terms, that means most users find 1–3 inhalations sufficient for a comfortable evening relaxation loop. Heavier consumers may chase the deeper body component with a few additional puffs, especially 30 minutes into the session. As always, start low and titrate slowly to find your personal sweet spot.
Terpene Profile and Aromachemistry
The terpene profile of Auto Douce Nuit is best described as sweet-herbal with grounding spice, a pattern suggestive of myrcene, beta-caryophyllene, and limonene as anchors. Myrcene, often dominant in indica-forward lines, is associated with earthy-sweet notes and a calming, body-forward effect. Beta-caryophyllene can add peppery edges and is notable for its activity at CB2 receptors, a pathway linked to anti-inflammatory signaling in preclinical models. Limonene contributes lifting citrus tones and can impart a clean, bright quality to the bouquet.
Linalool may be present in supportive amounts, especially in phenotypes that lean floral-lavender. Humulene can amplify woody, herbal facets and may synergize with caryophyllene for a rounded spice finish. Terpinolene, while less likely to dominate in an indica-leaning auto, could appear as a light, fresh top note in certain plants. Overall terpene totals in well-grown autos often land in the 1.0–3.0% by weight range, with top-tier samples occasionally exceeding that under optimal conditions.
Terpene expression is highly sensitive to cultivation practices. Maintaining canopy temperatures around 24–26°C in mid bloom and dropping to 22–24°C in late bloom helps preserve volatile compounds. A gentle dry at roughly 15–18°C and 58–62% RH for 10–14 days reduces terpene loss compared to fast, warm drying. Glass jar curing with periodic burps in the first two weeks further balances internal humidity and stabilizes aromatic complexity.
From a sensory standpoint, the blend produces a welcoming nose and a layered palate that evolves during cure. Early samples skew sweet and herbal, while month-old jars show deeper wood and spice with a smoother mouthfeel. The result is a versatile, evening-friendly profile that complements the strain’s name. For many, that makes Auto Douce Nuit a go-to for relaxed nighttime rituals and quiet social wind-downs.
Experiential Effects and Use Patterns
Auto Douce Nuit leans into a calming, body-centered experience with a gentle, clear headspace. Initial effects often include muscle looseness, soft warmth in the chest, and eased physical tension. Mentally, users describe a mellow uplift without edge, making it suitable for conversation, light reading, or music. The onset is steady rather than abrupt, which can help avoid anxiety spikes in sensitive individuals.
At moderate doses, the strain supports a peaceful evening routine—think cooking a simple meal, watching a film, or stretching before bed. Higher doses can deepen sedation, nudging toward couchlock near the tail end of the session. The come-down is typically smooth, with a restful afterglow lasting 1–2 hours. Many users reserve it for after-work decompression or pre-sleep preparation.
Functional capacity varies with dose and tolerance. Light inhalation keeps most people operational for low-demand tasks, while larger servings are best for stationary relaxation. Combining with caffeine can tilt the balance toward focus, though doing so late may blunt sleep benefits. As always, stacking substances increases variability and should be approached cautiously.
Tolerance behaves as expected for THC-dominant hybrids, rising with frequent use and receding after short breaks. Spacing sessions and rotating strains can help maintain desired effects at lower doses. For new users, 1–2 inhalations or a low-dose edible is a sensible pilot approach. Experienced consumers may find an optimal range where body relief is pronounced but mental clarity remains intact.
Potential Medical Uses and Evidence-Informed Considerations
The calming body effect and approachable headspace position Auto Douce Nuit for potential evening symptom management. Users commonly target stress, general anxiety, muscle tension, and transient sleeplessness. The analgesic potential of THC, combined with caryophyllene’s CB2 activity and myrcene’s sedative reputation, forms a plausible rationale for musculoskeletal discomfort and wind-down. Linalool, when present, is often associated with anxiolytic qualities in preclinical and aromatherapy literature.
For sleep, many people report improved latency—falling asleep faster—when dosing 60–90 minutes before bedtime. A small, consistent dose often outperforms sporadic larger doses in perceived sleep quality, reducing next-day fog. Individuals prone to late-night rumination may find the gentle mood softening helpful without heavy mental clouding. Edibles, if used, should be started at low milligram levels to avoid residual morning grogginess.
Pain relief can be situational. Neuropathic discomfort sometimes responds better to THC-dominant profiles, while inflammatory pain may benefit from caryophyllene-rich chemotypes that interact with CB2 pathways. For daytime pain, dose timing and route matter; small inhaled hits can provide quick relief without overly sedating effects. For nighttime pain, a slightly higher dose may leverage the strain’s sedative edge to support uninterrupted rest.
Medical cannabis is highly individualized, and strain responses vary. Patients should consult healthcare providers, especially when taking other medications, to rule out interactions and to establish safe dosing. Start low and go slow remains the guiding principle, particularly for those new to THC. Documenting dose, timing, effect, and side effects in a simple journal can help optimize a personal protocol over 1–2 weeks.
Comprehensive Cultivation Guide
Auto Douce Nuit is built for efficiency, with a typical seed-to-harvest window of about 9–11 weeks in controlled indoor conditions. Outdoors or in cooler rooms, add 1–2 weeks for full maturation. Because autos begin flowering based on age rather than light cycle, early vigor and stress avoidance are critical. Plan the environment, medium, and nutrient plan before germination to maximize the brief vegetative phase.
Germinate seeds using a 24–36 hour soak and paper towel method or directly in starter cubes, keeping temperatures at 22–25°C and RH near 70%. Transplant carefully into final containers soon after the first true leaves emerge to avoid root disruption later. Autos dislike transplant shock, so many growers start directly in 11–19 liter pots (3–5 gallons) for an uninterrupted root run. A light, aerated soil with 25–35% perlite and balanced, slow-release amendments suits novice growers well.
Lighting should provide 18–20 hours on and 4–6 hours off throughout the life cycle. Target PPFD of 400–600 µmol/m²/s in early growth, rising to 700–900 µmol/m²/s in bloom for best density and resin. Keep canopy temperatures at 24–26°C in day and 20–22°C at night, adjusting slightly cooler late in flower to protect terpenes. Relative humidity should track 65% in seedling, 55% in early veg, 50% in early bloom, and 45–50% in late bloom, with robust airflow.
Feed lightly at first, as autos are sensitive to overfertilization. In soil, begin at 25–40% of the manufacturer’s photoperiod dose once the plant has 3–4 nodes, then ramp to 60–75% in mid bloom if the plant shows hunger. A veg-leaning NPK like 3-1-2 suits the first half, shifting toward 1-3-2 or 2-4-4 formulations as buds set. Maintain pH at 6.2–6.8 in soil and 5.8–6.2 in hydro/coco, with EC guidelines of 1.0–1.4 in early growth and 1.6–2.0 in peak bloom, depending on cultivar response.
Training should be gentle and early. Low-stress training (LST) from week 2–3, bending the main stem to open the canopy, helps distribute light without stalling growth. Avoid topping after day 21 from sprout, as autos have limited time to recover. Defoliation should be moderate; remove leaves that block bud sites, but avoid large-strip defols that can shock the plant and slow flowering.
Watering practices make or break auto runs. Use the weight-of-pot method to avoid overwatering, allowing the top 2–3 cm of soil to dry before the next irrigation. In coco, frequent smaller irrigations maintain oxygenation, while soil favors deeper, less frequent waterings. Cal-Mag supplementation is often beneficial under LEDs, but keep total EC in check to avoid lockout.
Indoors, a 60×60 cm tent can comfortably house one to two Auto Douce Nuit plants, while a 120×120 cm tent can host four to six in 11–15 liter pots. Outdoors, choose a sunny spot with 6–8 hours of direct light, and aim for late spring through summer sowings to maximize intensity. In cooler regions, start indoors for 2–3 weeks before placing outside to gain momentum. Guard against heavy rain late in flower with shelter or selective leaf plucking to improve airflow.
Pest management starts with prevention. Sticky traps, clean intakes, and regular canopy inspections deter common indoor pests like fungus gnats and spider mites. Neem or biologicals such as Bacillus thuringiensis israelensis for larvae can be employed early, but avoid oily sprays after week three of flower. Outdoors, consider physical barriers against caterpillars and slugs and conduct sunset inspections when pests are active.
Auto Douce Nuit’s flowering period usually initiates around day 21–28 and ramps quickly. By week 6–7, buds swell and trichome heads become prominent, and by week 8–10, most plants approach harvest maturity depending on phenotype. Late-stage care emphasizes controlled humidity, mild feeding, and steady temperatures. Flushing in soil for 7–10 days with plain, pH-balanced water is common practice for a cleaner burn, though opinions vary by grower and medium.
Harvest, Drying, Curing, and Storage
Harvest timing should be guided by trichome maturity rather than calendar days alone. For a balanced effect, target milky trichomes with 5–15% amber, which often coincides with peak terpene expression. Pistil color can be a secondary indicator, but trichome heads are more reliable. Use a 60–100× loupe to assess clarity across multiple bud sites.
After cutting plants, aim for a slow dry at approximately 15–18°C and 58–62% relative humidity for 10–14 days. Gentle air movement, not directly on buds, helps prevent microclimates that can trigger mold. Avoid drying above 22°C, which accelerates terpene volatilization and can produce a hay-like aroma. Stems should snap rather than bend before trimming and jarring.
Curing improves flavor, smoothness, and perceived potency. Place trimmed buds into glass jars filled to about 70–80% volume to leave headspace, and burp jars daily for 10–15 minutes during the first week. Reduce burping frequency to every 2–3 days in week two, then weekly thereafter. Many growers report a notable improvement between weeks three and six of cure, with some benefits continuing for 8–12 weeks.
Store finished jars in a cool, dark place, ideally near 15–18°C and 55–60% RH, to preserve cannabinoids and terpenes. Light, heat, and oxygen degrade potency over time, with studies showing measurable THC losses over months under poor storage conditions. Use humidity control packs if living in very dry or very humid climates. For long-term storage beyond six months, consider vacuum sealing cured buds in glass and refrigerating to slow degradation.
Yield Expectations and Optimization Strategies
Yield depends on environment, pot size, light intensity, and phenotype. Indoors, many growers report 350–450 g/m² under efficient LEDs when plants receive 700–900 µmol/m²/s in bloom and are fed correctly. Skilled cultivators pushing high-performance environments can exceed 500 g/m² by optimizing light distribution, CO2, and irrigation. Outdoors, individual plants commonly yield 50–150 g, with 200 g possible in prime conditions and large containers.
To optimize yield, ensure strong early growth. Start in final containers, avoid transplant shock, and nail VPD targets to sustain transpiration and nutrient uptake. Keep the canopy even with early LST, and maintain a consistent distance from LED fixtures to hit target PPFD without light stress. In soil, top-dress at the start of flower with phosphorus and potassium to support bulking.
Nutrient balance matters as much as total quantity. Too much nitrogen in bloom can inhibit flower density and terpene production, while insufficient magnesium or sulfur can mute aroma. Many growers reduce N by 25–40% after week three of flower and increase K, supporting both resin and biomass. Monitoring runoff pH and EC helps catch imbalances before they impact yield.
Environmental stability is the multiplier on all other inputs. Keep day-night temperature swings within 4–6°C to protect metabolism, and maintain RH in the 45–50% range late in bloom to prevent botrytis in dense colas. Gentle canopy defoliation around week 3–4 of flower improves light penetration and airflow without undue stress. With these fundamentals, Auto Douce Nuit can achieve a convincing gram-per-watt performance in competent rooms.
Common Pitfalls, Pests, and Troubleshooting
Overfeeding is a frequent mistake with autos, and Auto Douce Nuit is no exception. The short veg window means recovery time from nutrient burn or heavy pruning is limited. Watch leaf tips for early signs of burn and adjust feed strength by 10–20% rather than making drastic changes. Similarly, overwatering in large pots can stall root oxygenation, slowing growth during the critical early weeks.
Light stress can also cap performance. Running LEDs too close, especially early, leads to tacoing leaves, bleaching, and stunted growth. Use a PAR meter or manufacturer guidelines to set height, and watch for upward leaf curl or pale tops as early warnings. Gradual intensity increases over the first 4–5 weeks let the plant acclimate.
Pests to watch indoors include fungus gnats, which thrive in wet media, and spider mites in dry, warm rooms. Yellow sticky cards help monitor populations, and allowing the top layer of soil to dry between waterings interrupts gnat breeding cycles. For mites, environmental control and early biologicals are preferred, as oil-based sprays can blemish pistils in flower. Outdoors, keep an eye on caterpillars, which can hollow buds; BT sprays in early flower and manual inspections at dusk are effective.
Mold pressure rises in dense autos late in bloom, especially with high ambient humidity. Improve airflow with strategic defoliation and oscillating fans, and keep RH at or below 50% in the final weeks. If a bud site shows botrytis, remove it generously and dispose of it away from the grow. Preventive hygiene and environmental stability are the best insurance for a crisp, clean finish.
Positioning Within the Market and Community Notes
Auto Douce Nuit sits comfortably in the modern autoflower niche that values reliability, approachable potency, and balanced effects. It appeals to home growers who want a fast, predictable cycle without micromanaging photoperiods. Its compact structure and forgiving demeanor make it a natural in small tents and balconies. Flavor and aroma are characterful without being polarizing, which broadens its audience.
Community visibility for the strain is supported by third-party directories and sitemap indexes, including entries discoverable on platforms such as CannaConnection. These listings, along with forum grow logs, help new cultivators calibrate expectations on timing, height, and feeding. That collective knowledge is a practical advantage with autos, where early decisions carry extra weight. As a result, Auto Douce Nuit benefits from a positive feedback loop of shared best practices and successful runs.
