Auto Relax is an autoflowering indica-dominant strain from Dispensario Seeds, bred from ruderalis and indica heritage to prioritize calm, body-focused effects. As the name suggests, it was designed with evening use and decompression in mind, offering a glide into tranquility rather than a jarring couch-lock. Growers prize the cultivar for its compact size, predictable time-to-harvest, and a terpene-forward profile that complements its soothing potency.
In the modern context of autoflower genetics, Auto Relax aligns with the trend toward higher potency and richer aromatic complexity. Independent reports on contemporary autoflowers show THC levels in the 20–25% range are achievable in top-tier lines, and Auto Relax typically lands in the mid-to-high potency bracket for indica autos. Its typical seed-to-harvest time of roughly 70–85 days gives home growers and micro-producers a fast, reliable turnaround.
Users commonly place Auto Relax into the evening-friendly category based on its mellow, full-body exhale and a gentle uplift that tapers into rest. This tracks with broader indica insights: indica-leaning buds are often associated with stronger physically sedating effects and deeper relaxation. For growers, that same indica influence translates into a stout frame, good calyx-to-leaf ratios, and resin that tends to stack well under strong indoor lighting.
History and Breeding Background
Dispensario Seeds created Auto Relax to meet a clear market demand for a dependable, no-fuss nightcap strain with true autoflower convenience. The breeder’s choice to leverage a ruderalis/indica base reflects the classic formula for reliability, structure, and speed. Ruderalis genetics impart the photoperiod independence, while indica lines contribute density, resin, and that unmistakable somatic ease.
While the strain’s exact parental selections are not public, the breeding objective reads like a checklist: compact morphology, terpene richness, and a consistent relaxation-forward effect. This formula echoes the broader trajectory of autoflower breeding over the last decade, which has transformed autos from “quick and light” to “fast and formidable.” In particular, the emphasis on terpene depth mirrors industry data showing consumer interest increasingly driven by aroma complexity alongside potency.
Autoflower programs have also leaned into grower practicality—fewer weeks to harvest, forgiving nutrient demands, and simple training. Auto Relax fits that mold, maturing on an accelerated timeline while staying manageable in modest indoor spaces. For small-scale growers and SOG practitioners, this combination of speed, structure, and effect has made autos like Auto Relax a reliable staple.
Genetic Lineage and Botanical Traits
Auto Relax descends from a ruderalis/indica foundation, a pairing known to produce compact plants with a rapid lifecycle. Ruderalis contributes the day-length independence that defines all autoflowers, typically pushing seed-to-harvest windows in the 10–12 week range. The indica influence shapes bud density, leaf morphology, and the soothing effect profile associated with evening use.
Phenotypically, growers can expect a stout central cola and several lateral branches that remain close to the main stem. Internodal spacing often stays tight, with cylindrical flower development that stacks efficiently under consistent light. Height typically lands in the 60–100 cm range indoors, depending on pot size, light intensity, and root-zone management.
Botanically, this cultivar favors a moderate leaf-to-calyx ratio, which simplifies trimming and aids airflow in the canopy. Resin production is a notable trait, with trichome coverage becoming obvious by week 5–6 from seed under optimized indoor conditions. The combination of resin, structure, and cycle length makes Auto Relax well suited to single-run harvest schedules in perpetual gardens.
Appearance and Morphology
Mature Auto Relax plants exhibit compact frames with a thick main stem and sturdy side branches. Fan leaves skew broad and dark green, consistent with indica-leaning genotypes. As flowering progresses, the canopy often takes on a frosted sheen from trichome density, especially on upper bracts.
Flowers tend to develop into chunky, golf-ball to soda-can sized clusters with a conical crown. Calyx stacking can be tight, and pistils commonly shift from ivory to a warm orange-brown as ripening proceeds. Under cool night temperatures late in bloom, some phenotypes may display faint anthocyanin expression, revealing subtle lavender hues around the sugar leaves.
Bud structure is generally firm, with a resin gloss that becomes pronounced after week 7. The calyx-to-leaf ratio is favorable, leaving sugar leaves tucked and easy to manicure. Finished buds typically weigh well after dry and cure due to their density, making them attractive to both personal and small-scale commercial growers.
Aroma and Flavor
Auto Relax leans into classic indica aromatics supported by a terpene ensemble that balances sweet, herbal, and earthy tones. Growers often report notes of red berries and soft floral accents layered over a base of fresh wood and baking spice. When jars are cracked after a proper cure, a sweet-sour top note can rise quickly, hinting at sparkling soda or sherbet-like fizz.
On the palate, expect a smooth draw that begins with a light sweetness before unfolding into herbal, woody, and peppery undertones. Beta-caryophyllene can introduce a gentle tingle on the exhale, while myrcene contributes to the rounded, almost velvety mouthfeel. A faint citrus twist from limonene brightens the finish, especially when flowers are vaporized at lower temperatures.
The terpene-forward experience tracks with broader observations that autoflower genetics have caught up to photoperiods in aromatic intensity. Independent lists of terpene-rich cultivars emphasize the value of high terpene loading alongside robust THC levels, and Auto Relax follows that philosophy. Proper curing at 58–62% RH for 3–5 weeks typically accentuates the sweet berry and spice layers.
Cannabinoid Profile and Potency
Auto Relax generally presents as a mid-to-high potency indica-dominant auto, with THC commonly reported in the 17–22% range under competent indoor conditions. In dialed-in rooms with strong lighting and optimal nutrition, outliers may push higher, reflecting a broader trend in modern autos that can reach the low-to-mid 20s for THC. The CBD fraction is usually minor, often below 1%, allowing the terpene ensemble and THC to steer the overall effect.
The intensity of the psychoactivity is moderated by the cultivar’s sedative lean, which can make the experience feel gentler than the raw THC number suggests. Users describe a gradual rise that stabilizes into calm focus before sliding into bodily ease. Compared to racier sativa-dominant autos, the headspace here is more grounded, with a lower likelihood of anxious over-stimulation at typical doses.
Contextually, industry discussions around 20–25% THC in elite autoflowers set an upper bar that shows what is possible with modern breeding. Auto Relax’s likely placement a notch below the very highest-potency autos can be a benefit for evening users who want robust relief without being overwhelmed. Vaporization temperatures around 175–190°C can emphasize flavor while maintaining a balanced, functional onset.
Terpene Profile and Chemistry
Auto Relax’s terpene spectrum often features myrcene, beta-caryophyllene, humulene, and pinene isomers as recurring anchors. Myrcene, frequently dominant in indica-leaning chemotypes, is associated with musky-sweet fruit notes and a perceived relaxing synergy with THC. Beta-caryophyllene contributes spicy, woody accents and is unique in that it binds to CB2 receptors, supporting a body-centric effect footprint.
Humulene adds a dry, hoppy earthiness that underscores the base of the bouquet and can complement appetite-moderating reports for some users. Alpha- and beta-pinene, detected across many indica autos, can brighten the nose with conifer and herbal lift, counterbalancing the heavier myrcene core. When present together, alpha- and beta-pinene have been discussed as potential allies for airway openness and inflammation management in general cannabis literature.
Secondary terpenes may include limonene and linalool, which inject citrus zest and a soothing floral facet respectively. Limonene is frequently linked to elevated mood and a cleaner finish on the palate, while linalool is often associated with relaxation cues and a lavender-like aroma. As a reminder, terpenes themselves do not produce intoxication in the way THC does, but they can modulate perceived effects and comfort.
Overall aroma intensity benefits from careful drying and curing, since terpenes are volatile and easily lost. Drying at 18–20°C and 50–60% RH over 10–14 days preserves a larger fraction of monoterpenes like myrcene and pinene. Maintaining a slow cure at 58–62% RH for at least three weeks can increase the perceived sweetness and depth by 10–20% according to blind-tasting feedback in many home grows.
Experiential Effects
The experiential arc of Auto Relax tends to begin with a light cerebral uplift that stabilizes quickly into bodily ease. Within 15–25 minutes after inhalation for most users, muscle tension softens and the urge to nest increases. The headspace remains coherent and friendly, with racing thoughts receding rather than spiraling.
As the session progresses, the strain’s indica gravity takes the wheel, shifting attention toward comfort and rest. This makes Auto Relax a strong candidate for evening wind-down routines, movie nights, or post-activity decompression. Reports of ease-of-sleep are common when consumed 60–90 minutes before bedtime, allowing the taper to align with circadian wind-down.
This experience aligns with broader cannabis insights that indica profiles often produce stronger physically sedating effects ideal for rest and relaxation. Industry roundups of top autoflowers for evening use often highlight strains that deliver instant gratification and relaxation with a gentle, feel-good high. Auto Relax fits squarely into that class, prioritizing calm over cardiovascular intensity or mental stimulation.
For daytime scenarios, microdosing via vaporizer can keep effects functional, particularly at temperatures under 185°C. Users who are sensitive to THC may find one or two small puffs sufficient to ease background tension without inducing heavy eyelids. Hydration and a light snack can help sustain comfort and prevent the occasional over-sedation.
Potential Medical Uses
While formal clinical trials on this specific cultivar are not available, Auto Relax’s chemotype suggests potential utility for stress mitigation, sleep initiation, and muscle tension relief. Myrcene-forward, indica-dominant profiles are frequently used anecdotally for insomnia, with many users reporting improved sleep onset when consumed in the evening. A low CBD content means the effects are primarily THC- and terpene-driven, resulting in a stronger subjective sedation for some patients.
Beta-caryophyllene’s interaction with CB2 receptors may support anti-inflammatory processes, which aligns with user reports of relief from exercise-related soreness or minor joint discomfort. Humulene and caryophyllene together contribute a spicy-earthy base that many associate with body-ease following physical strain. Alpha- and beta-pinene are often discussed in relation to airway comfort and cognitive clarity, potentially counterbalancing the fog sometimes associated with high myrcene.
Chronic pain patients often seek strains combining myrcene, caryophyllene, and linalool or limonene to address both physical discomfort and mood burden. Industry discussions note that terpenes like beta-caryophyllene, linalool, and limonene carry anti-inflammatory and analgesic associations, which can be meaningful when paired with moderate THC. That said, individual responses vary, and medical outcomes depend on dosage, delivery method, and personal physiology.
As a practical approach, vaporization at lower temperatures may offer sharper mental clarity while still addressing tension, whereas higher-temperature inhalation or edibles made from decarboxylated flower may deepen sedation. Patients should start low and go slow—beginning with 1–2 inhalations or 2.5–5 mg THC in edible form—and titrate over several sessions. Always consult a qualified medical professional when using cannabis for a medical condition, especially if taking other medications.
Comprehensive Cultivation Guide
Lifecycle and scheduling. Auto Relax typically completes in 70–85 days from sprout, with the faster phenotypes finishing around day 70 and bulkier expressions extending to day 80–85. Most plants begin noticeable preflower by days 18–24, so training and transplant decisions must be planned early. Aim to germinate directly into the final container or a plug that is transplanted by day 10 to avoid growth stalls.
Environment targets. Keep daytime temperatures at 24–26°C and nights at 20–22°C for steady metabolism. Relative humidity should begin around 65–70% in week 1–2, taper to 55–60% in mid-veg, and settle at 45–50% in late flower to manage mold risk. A VPD of 0.8–1.2 kPa across the cycle balances transpiration and nutrient uptake, reducing tip burn and edema.
Lighting strategy for autos. An 18/6 or 20/4 photoperiod from seed to harvest works well, with 18/6 offering a good efficiency-to-yield ratio. Target 300–400 µmol/m²/s PPFD in early veg and 600–900 µmol/m²/s in peak flower, equating to a DLI of roughly 20–25 mol/m²/day in early growth and 35–45 mol/m²/day later. Autoflowers generally respond well to consistent intensity instead of large step changes.
CO2 and airflow. Supplemental CO2 at 800–1,000 ppm can add 5–15% yield in tightly sealed, high-light rooms if temperature, nutrition, and irrigation are optimized. Maintain uniform air movement with 0.3–0.7 m/s canopy breeze to prevent microclimates that raise mold risk. Exchange room air adequately if not enriching CO2 to keep VPD and temperature stable.
Media and containers. For soil or peat-based mixes, use 3–5 gallon (11–19 L) pots to balance root volume and cycle time; in coco, 2–3 gallon (7.5–11 L) can suffice with frequent fertigation. Ensure drainage rates above 20% runoff when fertigating in inert media to prevent salt buildup. A loose, airy substrate with 25–35% perlite improves oxygenation and root vigor.
Nutrition and EC. Start mild at 0.8–1.0 mS/cm EC in early veg, progress to 1.2–1.6 mS/cm mid-cycle, and hold 1.6–2.0 mS/cm late flower depending on cultivar appetite and runoff readings. Keep pH at 5.8–6.2 for coco/hydro and 6.2–6.8 for soil to maintain nutrient availability. Monitor runoff EC weekly; rising values signal salt accumulation and the need for a gentle flush or increased runoff.
Irrigation cadence. In soil, water to 10–20% runoff every 2–4 days as pots lighten to 50% of saturated weight. In coco, aim for 1–3 feeds daily as root mass increases, maintaining frequent small irrigations rather than heavy, infrequent ones. Avoid overwatering in weeks 1–3, as autos dislike early root-zone hypoxia that can shave 10–20% off final yield.
Training and pruning. Use low-stress training (LST) between days 10–30 to open the canopy and keep the main cola level with the top laterals. Topping can work in vigorous phenos but should be done only once, around the 4th–5th node by day 15–20, to avoid stunting. Defoliate lightly, removing only leaves that block key sites; aggressive stripping after day 30 can reduce bud size in autos.
SOG suitability. Auto Relax’s compact form is well-suited to Sea of Green, especially under 18/6 lighting. Space 16–25 plants per square meter in 7–11 L pots to create an even canopy, or run 9–12 plants/m² in 12–19 L for thicker colas. Industry notes highlight certain autos as particularly pleasant to use in the evening with great sleep quality; strains like Auto Relax deliver that effect while fitting SOG density targets.
Yield expectations. Indoor yields of 350–500 g/m² are realistic with competent lighting and fertigation; advanced dial-in with CO2 can push higher. Per-plant yields of 50–120 g are common depending on pot size, training, and phenotype. Outdoors, expect 50–150 g per plant in temperate climates with full sun and at least 6–8 direct light hours daily.
Outdoor and greenhouse notes. Plant after the last frost when nighttime temperatures stay above 12–14°C, as cold nights slow autos disproportionately. Autos thrive under long summer days; two to three successive runs are possible at latitudes 40–55°N between late spring and early fall. Use raised beds or fabric pots for warmer root zones and faster dry-backs in humid regions.
Integrated pest management. Begin with prevention: sticky cards, regular canopy inspections, and sanitation to reduce pest ingress. Biologicals like Bacillus subtilis and Trichoderma in the root zone, and Beauveria bassiana or neem seed meal foliar in veg, can deter common pressures. Avoid heavy foliar sprays after week 4–5 to preserve trichomes and prevent residual flavors.
Flowering support and staking. As buds bulk up, add plant yoyos or bamboo stakes to prevent branch collapse, especially in high-PPFD rooms. Maintain even canopy height to ensure uniform PPFD and bud development. Keep oscillating fans angled to skirt direct blast on colas, which can desiccate pistils prematurely.
Harvest timing. Monitor trichomes with 60–100× magnification beginning day 60, looking for a shift from clear to cloudy with 5–15% amber for balanced potency. Harvesting with 20–30% amber generally increases perceived sedation, which many evening users prefer. Pistil color is secondary; rely on trichomes for final decisions.
Drying and curing. Aim for 10–14 days dry at 18–20°C and 50–60% RH with gentle airflow but no direct fan on flowers. After dry, cure in airtight containers at 58–62% RH, burping daily for the first week and weekly thereafter for 3–5 weeks. This regimen preserves volatile monoterpenes and enhances the berry-spice bouquet by an estimated 10–20% in sensory panels.
Post-harvest handling. Trim cold if possible to retain resin brittleness and reduce smear; glove changes every 15–20 minutes maintain cleanliness. Store finished jars in the dark at 15–20°C, as terpene loss accelerates above 25°C and with light exposure. Proper storage preserves potency and aroma, ensuring consistent effects over 6–12 months.
Blending and use strategy. Some users blend terpene-rich cultivars to broaden effects, a practice noted to produce superior taste and perceived breadth of relief. Pair Auto Relax with a limonene-forward sativa in a 70:30 ratio for daytime calm, or add a linalool-heavy cultivar at 50:50 for deeper nighttime sedation. Keep total dosage stable when blending to avoid unintentionally doubling THC intake.
