Written by Ad OpsOrigins and Breeding History
Auto Dosi is an autoflowering, indica-leaning cultivar bred by G13 Labs, a European seedmaker known for turning high-impact photoperiod genetics into compact, fast-finishing autos. The name and aromatic profile align it with the broader “Dosi/Do-Si-Dos” family, adapted here with Cannabis ruderalis to enable flowering by age rather than by light cycle. That shift changes how growers plan a run, cutting the timeline to harvest while preserving much of the weight, resin density, and dessert-like bouquet of its photoperiod relatives.
The rise of autos like Auto Dosi coincided with advances in breeding that pushed potency and terpene output well beyond the early 2010s. Modern autos commonly complete seed-to-harvest in 70–85 days under 18–20 hours of daily light, compared to 110–140 days for many photoperiod indicas grown from seed. That time savings is significant for home and commercial growers alike, enabling more harvests per year and reducing energy-per-gram metrics in controlled environments.
G13 Labs positioned Auto Dosi for cultivators seeking the classic, creamy-cookie-meets-citrus profile associated with Dosi lines without the scheduling constraints of a 12/12 light flip. Whereas legacy photoperiod strains require precise control of daylength, Auto Dosi’s ruderalis component makes flowering automatic after a short juvenile period. This design increases consistency in small tents and micro-grows and lowers the barrier to entry for first-time growers.
Genetic Lineage and Heritage
According to the provided context details, Auto Dosi’s heritage is ruderalis/indica, reflecting a purposeful cross between a Dosi-style indica parent and a stabilized ruderalis donor. The ruderalis side contributes autoflowering and cold resilience, while the indica side brings dense inflorescences, broadleaf morphology, and a heavy resin load. This combination is typical of modern autos that aim to preserve boutique terpene profiles while ensuring a short, predictable life cycle.
Although G13 Labs has not publicly disclosed a detailed pedigree for Auto Dosi, the naming convention and sensory profile strongly indicate a Do-Si-Dos lineage. Do-Si-Dos itself is generally traced to OGKB or GSC lineages crossed with Face Off OG, producing an indica-leaning hybrid with potent limonene–caryophyllene–linalool aromatics. Translating that chemistry into an autoflower requires multiple generations of selection to recover terpene intensity and calyx density after introducing ruderalis genetics.
In practice, the line behaves like an indica-dominant auto with high trichome density and a compact structure. Most growers report squat, well-branched plants with an early onset of preflowers around day 18–25 from sprout. The result is a cultivar that feels familiar to anyone who has grown Dosi or Cookies derivatives, but with the daylength independence and tighter schedule expected of contemporary autos from established breeders like G13 Labs.
Visual Appearance and Bud Structure
Auto Dosi typically grows to a medium-short stature, with most phenotypes ranging from 60–100 cm indoors under 18–20 hours of light. The canopy tends to be bushy with moderate internodal spacing, which encourages multiple colas when low-stress training is applied. Leaves are broad and slightly glossy, consistent with an indica-leaning background.
Mature flowers exhibit a high calyx-to-leaf ratio for an autoflower, producing rounded, spade-shaped colas with a frosty appearance. Coloration is usually olive to forest green, with lime green sugar leaves and abundant pumpkin-orange pistils. Under cooler night temperatures (15–18°C late bloom), some phenos express lavender or plum tones along the bract edges.
Trichome coverage is one of the standout features, with visibly dense gland heads creating a silver-white sheen at peak ripeness. This resin load is consistent with Dosi-style lines and contributes to an oily, sticky hand-feel during trimming. The overall bag appeal is elevated by the firm bud density and symmetrical cola formation, traits that persist even in smaller containers.
Aroma and Bouquet
Auto Dosi leans into a dessert-forward bouquet with sweet dough, vanilla cream, and powdered sugar notes underscored by lime zest and fresh-cut pine. On the back end, expect peppery spice and faint earthy undertones, consistent with a caryophyllene–myrcene signature. When properly grown and cured, the nose opens quickly upon jar crack, and the citrus layers intensify with light agitation.
In controlled grows, total terpene content of well-bred autos often lands around 1.5–3.0% of dry weight, and Auto Dosi is commonly perceived near the upper half of that range when conditions are ideal. Limonene and caryophyllene tend to dominate, with linalool and humulene contributing floral and herbal depth. The result is a layered, confectionary profile that stays noticeable even in small spaces.
Aromatics are sensitive to post-harvest handling, and terpenes can volatilize rapidly if dried too warm or too fast. Managing a slow dry (10–14 days at 60°F/60% RH) helps retain the citrus–cream top notes in the finished flower. Once cured to a stable 58–62% RH, Auto Dosi’s aroma is persistent and readily translates into vapor and smoke.
Flavor and Mouthfeel
The flavor traces the aroma closely, delivering cookie-dough sweetness on the inhale followed by lime peel, pine resin, and a pinch of black pepper. Many tasters note a creamy mouthfeel that softens the spice, leading to a pastry-like finish rather than a harsh, pepper-forward aftertaste. Combustion at modest temperatures preserves the confectionary top notes best.
In vaporizers, setting temperatures around 175–185°C (347–365°F) emphasizes limonene and linalool for a bright, dessert-like experience. Increasing to 190–200°C (374–392°F) shifts the balance toward caryophyllene and humulene, enhancing peppery and herbal tones with a denser, more resinous mouthfeel. Above 205°C (401°F), expect the citrus to recede as heavier sesquiterpenes dominate.
The finish is medium-long, with sweet-citrus lingering for 30–60 seconds and a light pine afterglow. Proper curing deepens the vanilla and pastry components, giving a balanced sweet-to-spice ratio in the exhale. Harshness is usually minimal when the flower is dried slowly and nitrogen-rich leaf matter is limited by gentle defoliation in late flower.
Cannabinoid Profile and Potency
Auto Dosi is an indica-leaning autoflower that commonly tests in the mid-to-high THC band for autos, with reported batches landing in the 18–22% THC range. At 20% THC, each gram of dried flower contains roughly 200 mg of delta-9-THC, making a typical 0.25 g session deliver about 50 mg of total THC before combustion losses. CBD is generally low (<1%), while minor cannabinoids like CBG often appear in the 0.3–1.0% window.
Potency varies with environmental control, nutrition, and post-harvest technique. Under steady PPFD and a correctly managed vapor pressure deficit (VPD), autos can express their full resin potential, narrowing batch-to-batch variance. Conversely, overfeeding nitrogen in early flower or drying above 70°F tends to reduce both measured THC and perceived potency.
For inhaled use, subjective intensity peaks within 15–30 minutes and persists 2–4 hours, typical for high-THC indica-leaning cultivars. Edible or rosin infusions made from Auto Dosi will follow oral pharmacokinetics, with onset in 45–90 minutes and a longer 4–8 hour plateau. Given the low CBD content, the overall psychoactive character remains THC-forward unless blended with CBD-rich material.
Terpene Profile and Chemistry
Auto Dosi’s terpene fingerprint typically centers on limonene, beta-caryophyllene, and linalool, with myrcene and humulene in supportive roles. In well-grown samples, limonene often accounts for 0.3–0.6% of dry weight, caryophyllene for 0.2–0.5%, and linalool for 0.08–0.25%. Combined total terpenes commonly measure 1.5–3.0% in dialed-in conditions for autos, a range that aligns with premium indoor results.
Beta-caryophyllene is noteworthy as a dietary cannabinoid that selectively engages CB2 receptors, a mechanism explored for anti-inflammatory effects. Limonene has been correlated with elevated mood and citrus-forward aroma intensity, and linalool is associated with floral notes and potential calming effects. Myrcene contributes herbal undertones and is frequently linked with a heavier body sensation, while humulene adds a gentle, hop-like dryness.
Volatility matters for preserving these compounds. Limonene and linalool are more fragile during drying and curing; keeping temperatures near 60°F and RH near 60% slows evaporation and oxidation. Vaporization temperatures between 175–195°C make it easier to experience the brighter top-end flavor spectrum before sesquiterpenes take over.
Experiential Effects and Onset
Users commonly describe Auto Dosi as offering a calm, euphoric onset that settles into soothing, full-body relaxation. The headspace is clear-to-dreamy at low-to-moderate doses, with a warm, content mood uplift often noted in the first 20 minutes. As the session progresses, muscle ease and a gentle heaviness build, typical of indica-leaning Dosi lines.
Onset windows depend on route of administration. Inhalation typically shows initial effects in 2–5 minutes, with the peak around 15–30 minutes and a total duration of 2–4 hours. Edibles or tinctures prepared from Auto Dosi decarboxylate well and provide a slower, deeper arc that can extend to 6–8 hours.
Dose sensitivity varies. Newer consumers often find 1–3 inhalations sufficient, while experienced users may prefer 0.2–0.35 g per session for balanced euphoria without sedation. At higher doses and later in the evening, the cultivar can become markedly couch-friendly, making timing and setting important for daytime use.
Potential Medical Applications
The THC-forward yet soothing character of Auto Dosi suggests potential utility for stress relief, mood elevation, and evening relaxation. Terpene synergy may support these effects: limonene has been studied for mood-related benefits, and linalool is associated with calming properties. Beta-caryophyllene’s CB2 activity has drawn research interest for inflammatory modulation, which may align with anecdotal reports of muscle and joint comfort.
Observational data in the cannabis literature suggest inhaled cannabis can produce meaningful short-term reductions in pain and headache severity. For example, app-based studies have reported average reductions in headache severity approaching 47% and migraines around 49% following inhalation sessions, though results vary widely by dose and chemovar. While Auto Dosi itself is not a clinical product, its THC-dominant profile with caryophyllene and myrcene could be aligned with these symptomatic targets in some users.
Sleep is another area of interest when indica-leaning chemovars are used later in the day. Myrcene and linalool are frequently cited by patients who seek wind-down support, and surveys often find improved sleep quality after evening sessions. As with all cannabis use, responses are individualized, and patients should consult healthcare providers, especially if taking medications that interact with the endocannabinoid system.
Comprehensive Cultivation Guide: Planning and Environment
G13 Labs bred Auto Dosi as a ruderalis/indica autoflower, making environment and timing the core of cultivation success. Plan for a 70–85 day seed-to-harvest window, with the fastest phenotypes finishing near day 70 and resin-heavy phenos pushing to day 80–85. Autos do not pause the clock, so a stable, dialed-in environment from day 1 yields the best outcomes.
Lighting: Maintain 18/6 or 20/4 schedules throughout the run; both work well, with 20/4 providing a small boost in daily light integral (DLI). Target PPFD around 300–450 µmol/m²/s in early veg, ramping to 650–800 µmol/m²/s in mid flower for photonic efficiency without light stress. These intensities commonly correspond to 30–45 DLI for autos, depending on hours of light.
Climate: Keep daytime temps 24–28°C and nights 18–22°C. Manage VPD around 0.8–1.1 kPa in veg and 1.2–1.5 kPa in flower for consistent gas exchange without desiccation. Humidity bands of 60–70% (seedling), 55–65% (veg), and 45–55% (flower) are dependable targets for terpene retention and mold prevention.
Medium and containers: Autos thrive in aerated media like coco coir–perlite (70/30) or light soil blends. Use 11–19 L (3–5 gal) fabric pots for full-size plants; micro runs can use 7 L (2 gal) with modest yield trade-offs. Fabric pots aid oxygenation and root-prune naturally, reducing overwatering risk.
Cultivation Guide: Germination, Early Veg, and Training Strategy
Germinate seeds using a reliable method: pre-soak 12–18 hours in room-temperature water (optional), then place in a moist starter cube or 0.5–1 cm deep in the final container. Maintain 24–26°C and 90–100 µmol/m²/s PPFD until cotyledons fully open. Seedlings usually emerge within 48–96 hours and begin true leaf development by day 4–6.
Water lightly in a ring around the seedling with 50–150 mL as needed, avoiding saturation in the early root zone. Begin gentle airflow once plants are stable to strengthen stems and deter damping-off. In coco, start with EC 0.8–1.0 mS/cm and pH 5.8–6.0; in soil, water at pH 6.2–6.6 with minimal nutrients for the first 10 days.
Training: Prioritize low-stress training (LST) rather than high-stress topping, since autos have a fixed timeline. Begin LST around day 14–18 by bending the main stem slightly to open the canopy, securing with soft wire or plant clips. Avoid topping after day 21; if topping is attempted, do it once at the 3rd–4th node by day 18 to reduce risk of yield loss.
Defoliation should be conservative and targeted. Remove only leaves that block critical budsites or restrict airflow, focusing on 5–10% leaf mass per session. Over-defoliation can slow autos, so spread any canopy work over multiple days.
Cultivation Guide: Nutrition and Irrigation
Autos like Auto Dosi typically need less nitrogen than comparable photoperiod indicas, especially after day 21. A practical macro target in coco during early veg is N–P–K near 120–150 ppm N, 40–60 ppm P, and 150–200 ppm K, with 90–120 ppm Ca and 40–60 ppm Mg. As preflowers appear, reduce N by 25–40% and increase K into the 200–250 ppm range to support flower bulking.
In soil, many growers succeed with a light, balanced dry amendment program and top-dressing at day 21–28, followed by a bloom-biased amendment at day 35–40. Keep total EC modest for autos: 1.2–1.6 mS/cm in mid flower and up to 1.8 mS/cm for heavy feeders. Always calibrate to plant feedback—dark, clawed leaves indicate excess nitrogen or overwatering.
Irrigation frequency depends on media and pot size. In coco with 70/30 perlite, many growers water daily or twice daily in late veg and flower to 10–20% runoff, maintaining consistent root-zone EC. In soil, water more deeply but less frequently, allowing the top 2–3 cm to dry before the next irrigation to protect root oxygenation.
Additives like silica (40–60 ppm) can improve stem strength and leaf turgor, and carbohydrate or amino supplements are optional but can support microbe activity in organic systems. Keep sodium and chloride low to prevent antagonism with potassium and calcium uptake. Monitor leaf tissue for interveinal chlorosis; if present, check pH and Mg availability first.
Cultivation Guide: Flowering, Ripening, and Yield
Auto Dosi commonly shows sex and early flowers by day 18–25, with visible bud set by day 28–35. Mid bloom typically spans day 35–60, with resin ramping from day 45 onward. Late bloom extends into day 65–80, depending on phenotype and environmental stability.
Lighting remains at 18/6 or 20/4 throughout flower; keep PPFD in the 650–800 µmol/m²/s range, stepping down slightly in the final week if plants show light stress. Maintain VPD 1.2–1.5 kPa and RH 45–50% to balance trichome production and mold prevention. Gentle leaf thinning around day 42–49 can improve airflow and light penetration without stressing the plant.
Expected yields vary with pot volume, light intensity, and training. Indoors, experienced growers often report 400–550 g/m² with efficient LED fixtures, while single plants in 11–19 L pots can produce 60–120 g per plant under strong lighting. Outdoors or in patios, 50–160 g per plant is typical, with the higher end achievable in warm, sunny climates and well-amended beds.
Ripeness indicators include swollen calyxes, receded pistils, and a trichome field that is mostly cloudy with some amber. For a balanced effect, harvest when trichomes are roughly 70–85% cloudy and 5–15% amber. If seeking a heavier, more sedative profile, allow amber to rise toward 20–25%, watching carefully for terpene fade past optimal windows.
Integrated Pest Management and Disease Prevention
Autos benefit from preventative integrated pest management (IPM) because treatment windows are short. Start clean: sanitize tents, intake filters, and tools before each run and quarantine new clones or plants from other grows. Maintain positive pressure in the grow space and use fine mesh on intakes to reduce pest ingress.
Scouting is crucial. Inspect undersides of leaves 2–3 times per week, looking for stippling or webbing that indicates spider mites, or white clusters that suggest aphids or mealybugs. Sticky cards placed at canopy height help monitor fungus gnats and thrips; replace weekly to track trends.
Environment is your first line of defense against disease. Keep RH within target bands and maintain strong, non-turbulent airflow through and above the canopy. To prevent botrytis in dense colas, avoid wetting flowers, space plants adequately, and prune minor interior shoots that will not develop into productive sites.
If intervention is required, prioritize low-impact solutions early in veg, such as diluted insecticidal soaps or essential-oil-based products, and discontinue sprays once flowers form. Biological controls like Bacillus thuringiensis israelensis (BTi) for gnats and beneficial mites for thrips/mites can be integrated safely. Always follow product labels and observe preharvest intervals.
Harvest, Drying, and Curing
Once trichome targets are met, harvest in the coolest part of the dark cycle to preserve volatile terpenes. Many growers prefer a whole-plant hang to slow the dry, especially for dense indica-leaning flowers like Auto Dosi. Remove large fan leaves at chop, leaving sugar leaves intact to protect trichomes during the first few days.
Aim for the classic 60/60 dry: 60°F (15.5°C) and 60% RH with gentle air exchange, avoiding direct airflow on the flowers. Under these conditions, drying typically takes 10–14 days, with stems snapping but not shattering when ready. Faster dries at warmer temperatures can reduce terpene content and increase harshness in the smoke.
After drying, trim carefully and place buds into airtight glass jars at 58–62% RH. Cure for at least 2–4 weeks, burping daily for the first 7–10 days to release moisture and exchange air, then less frequently as RH stabilizes. Proper curing can improve the perceived sweetness and lime-driven top notes and may increase smoothness by reducing residual chlorophyll.
For long-term storage, maintain jars in a cool, dark place between 55–60°F with minimal temperature swings. Consider humidity control packs calibrated to 58–62% RH for stability. Target water activity (aw) around 0.60–0.65 to minimize mold risk while maintaining pliable, flavorful flower.
Outdoor and Greenhouse Considerations
Auto Dosi’s ruderalis component can improve resilience outdoors, enabling spring and late-summer runs before frost in temperate zones. Plant once night lows reliably exceed 10°C to accelerate early growth and reduce damping-off risk. In full sun, plan for 75–85 days from sprout to harvest and water deeply during heat spells to prevent stress-induced stunting.
Choose well-drained beds or 19–38 L (5–10 gal) fabric pots with a living soil or organic super soil. Top-dress with balanced amendments at week 3–4 and a bloom-focused mix at week 5–6, incorporating calcium and magnesium if your water is soft. Mulch helps regulate root-zone temperatures and suppress weeds.
Greenhouses offer season extension and shelter from rain during late flower, critical for dense indica-leaning colas. Ventilation is essential—aim for multiple air exchanges per hour and deploy horizontal airflow fans to prevent microclimates. If humidity spikes, consider a dehumidifier to maintain 50–55% RH in late bloom and reduce botrytis risk.
Quality, Safety, and Compliance Notes
If you plan to process Auto Dosi into concentrates, remember that autos can produce impressive resin for dry sift or ice water hash when grown under stable conditions. Wet trim for fresh-frozen material as soon as possible after harvest to retain terpene content; colder, faster freezing reduces ice crystal damage. Expect a terpene-forward extract aligning with limonene, caryophyllene, and linalool dominance.
Consumer safety begins with clean inputs. Avoid systemic pesticides and respect preharvest intervals for any allowable IPM products in your region. If testing is available, check final flower for pesticides, heavy metals, and microbial contaminants to ensure a clean experience.
Legal compliance varies by jurisdiction. Always follow local regulations regarding plant counts, extraction methods, and possession limits. G13 Labs distributes seeds as novelty products in some markets, so verify your local cultivation laws before germination.
Why Auto Dosi Stands Out
Auto Dosi merges the confectionary, citrus-spice charm of Dosi-lineage indicas with a streamlined autoflower schedule from G13 Labs. It offers strong indoor yields for an auto, finishing in roughly 10–12 weeks from seed with dense, resin-coated flowers. The terpene profile is sophisticated yet accessible, translating to flavorful vapor and smooth smoke when handled carefully.
For growers, consistency across small tents and balcony gardens is a highlight. The cultivar adapts well to 18/6 or 20/4 lighting, tolerates modest training, and responds to bloom-focused nutrition once preflowers appear. For consumers, the balance of uplifting euphoria and relaxing body effects makes it a reliable evening choice without overwhelming complexity.
In short, Auto Dosi leverages its ruderalis/indica heritage to deliver predictable cultivation timelines and a premium sensory experience. With correct environment management and conservative nitrogen in early flower, it can rival many photoperiod counterparts in bag appeal. Combined with G13 Labs’ breeding reputation, it’s a compelling option for both first-time auto growers and seasoned enthusiasts.
