Auto Haze is an autoflowering Haze hybrid developed by Gea Seeds, blending ruderalis, indica, and sativa genetics into a fast-cycling, aromatic cultivar. It aims to deliver the classic cerebral lift of Haze while finishing in a compact 70–85 days from sprout under stable indoor conditions. Typical plants reach 70–110 cm indoors and 90–140 cm outdoors, producing elongated, resinous colas with citrus-pine incense and a clear-headed effect.
As a modern auto, Auto Haze is tuned for simplicity and speed, thriving under 18–20 hours of daily light without a photoperiod trigger. Growers commonly report indoor yields of 350–500 g/m² with efficient lighting and 60–150 g per plant outdoors, depending on latitude and season length. THC commonly lands in the mid-teens to high teens (about 14–20%), with CBD usually below 1%, supporting a bright, energetic experience.
Within broader cannabis genealogy, Auto Haze appears in lineage notes and crosses beyond its original packaging. According to SeedFinder’s genealogy notes, an Auto Haze entry is referenced as an ancestor or cross partner in lines such as Lemon Venom (Cream of the Crop Seeds) and combinations featuring Sensi Star (Paradise Seeds) x Big Bud (Sensi Seeds). This signals how the cultivar’s autoflowering Haze traits have informed later hybrids, particularly where breeders sought faster cycles with sativa-forward aromas.
For consumers, Auto Haze offers a daytime-friendly profile with assertive terpinolene–limonene–pinene aromatics. For cultivators, it provides a straightforward schedule, minimal training requirements, and resilience derived from ruderalis heritage. Together, those traits have positioned Auto Haze as a reliable entry point into Haze flavors without the notoriously long flowering times of classic photoperiod Hazes.
History and Breeding Origins
The Haze family traces back to the 1960s–70s Santa Cruz scene, where legendary long-flowering sativas were selected for soaring, cerebral effects and incense-citrus aromas. While the original Hazes could flower 12–16 weeks, modern breeders have refined the profile into more manageable timelines. Autoflowering technology, derived from Cannabis ruderalis, compressed that timeline even further, enabling full seed-to-harvest cycles in under three months in many cases.
Gea Seeds created Auto Haze to deliver a recognizable Haze high and smell without the long wait. By incorporating ruderalis into a Haze-heavy hybrid and tempering morphology with indica support, they set a target of 70–85 days from sprout. This speed addresses common market constraints by allowing multiple indoor runs per year and predictable single-season outdoor harvests in temperate regions.
The rise of autos over the 2010s aligned with improvements in potency, aroma fidelity, and yield. Early autos often capped THC around 10–12%, but contemporary lines commonly achieve 15% or higher while maintaining 1.0–2.5% total terpene content when grown and cured carefully. Auto Haze sits squarely in that modern cohort, aiming for potency and a strong terpene signature without sacrificing cycle time.
Genealogical references illustrate Auto Haze’s influence across breeding projects. SeedFinder’s lineage notes list “Auto Haze” in the ancestry of certain hybrids, including Lemon Venom (Cream of the Crop Seeds), and combinations involving Sensi Star x Big Bud. While these mentions are broader than Gea Seeds’ specific selection, they underscore how autoflowering Haze traits have become modular building blocks in contemporary hybridization.
As autoflower acceptance grew, Auto Haze found a niche among home growers seeking energetic sativas without the complexity of photoperiod management. Its reputation centers on user-friendly cultivation, lively daytime effects, and a fragrant terpene set that reads unmistakably Haze. That combination helped move the cultivar from curiosity to staple in many small-scale gardens.
Genetic Lineage and Heritage
Auto Haze is a ruderalis/indica/sativa hybrid, reflecting a formula common to modern autos: ruderalis for the autoflower trait, sativa for the Haze character, and indica to stabilize structure and reduce extreme flowering times. In practice, this leads to a sativa-forward effect with better-than-expected vigor and manageable internodal spacing. The ruderalis input is primarily phenological—conferring the photoperiod independence—while the chemotype skews toward classic Haze.
Because different breeders produce multiple “Auto Haze” versions, exact parental lines can vary, but Gea Seeds’ selection emphasizes sativa aromatics and uplift. In autos, indica contributions often tighten bud structure and bolster trichome density without significantly dulling the high. That seems true here: growers commonly note elongated colas with moderate density rather than the extreme airiness of older Hazes.
Haze ancestry typically includes complex sativa backgrounds with roots in Southeast Asian, South Asian, and Central American genetics. The result is a terpene profile that often favors terpinolene and alpha-pinene, with supporting limonene, ocimene, and caryophyllene. Auto Haze captures that hallmark incense-citrus-pine bouquet while compressing the life cycle through ruderalis inheritance.
Lineage data in public genealogy sources further places “Auto Haze” into hybrid networks beyond a single brand. SeedFinder’s genealogy pages indicate Auto Haze has been used or cited in crosses such as Lemon Venom and combinations with a Sensi Star x Big Bud background. These references are useful context for breeders, showing how an autoflower Haze module can impart citrus-pine expression and quick finish times into new projects.
Overall, expect a sativa-leaning chemotype with a moderate indica contribution for sturdier morphology and yield. The ruderalis component rarely dominates above the level needed for the autoflower trait, leaving the sensory profile clearly Haze. This balance is a major reason Auto Haze fits well into compact indoor spaces and short outdoor seasons.
Visual Appearance and Plant Morphology
Auto Haze plants typically show a mid-sized stature with a central spear cola and several productive satellite branches. Internodal spacing is moderate, avoiding the extreme stretch that plagues older Haze lines while still allowing ample airflow. Leaves often express a slender, sativa-forward morphology early, then thicken slightly as flowering advances.
Buds form as elongated, tapered colas with occasional foxtailing under high light or heat, a trait not uncommon in Haze-leaning genetics. Calyxes stack in a staggered pattern, creating a rippled surface that gleams when trichomes ripen. Expect pistils to shift from vivid orange to deeper rust as harvest approaches.
Coloration ranges from lime to forest green, with darker sugar leaves that can purple slightly under cool night temperatures or late-stage senescence. Trichome coverage is robust for an auto, often leaving a frosty cast over top colas by week 8–10 from sprout. Under magnification, stalked glandular trichomes are abundant, with cloudy heads dominating near peak maturity.
Branching is responsive to gentle low-stress training (LST), spreading the canopy and reducing apical dominance without halting growth. Many growers avoid topping autos due to the short vegetative window, and Auto Haze is no exception—early, gentle bending usually outperforms cuts. A final height of 70–110 cm indoors is common in 11–15 L containers, with 20–30% additional stretch outdoors.
Root systems establish quickly if seedlings are sown directly into their final container. Transplant shock can cost several days in an auto’s compressed schedule, so careful handling or direct seeding is recommended. Healthy plants exhibit a sturdy central stem and a symmetrical crown that fills nicely under 18–20 hours of light.
Aroma Profile
Auto Haze carries a classic Haze bouquet centered on terpinolene’s fresh, resinous character. Primary notes include electric citrus peel, green pine needles, and a sweet-herbal incense reminiscent of cedar shavings. Secondary hints of sweet basil, green mango, and floral spice often appear as buds dry and cure.
During flowering, the aroma ramps up conspicuously around weeks 5–7 from sprout, making carbon filtration prudent for indoor cultivation. Rubbing a stem releases sharp lemon-pine and a peppery edge likely tied to caryophyllene and pinene. Dried flowers retain the high-tone brightness, though deeper incense and woody facets dominate after a long cure.
Terpene intensity is strongest in the top third of the canopy, where light and airflow are optimal. Growers who keep day temperatures around 24–27°C and maintain moderate RH (45–55%) generally report fuller aromatic expression. Rapid drying or high-heat conditions can flatten the citron-wood top notes by as much as 20–30% based on practical grower experience.
Grinding a cured sample typically releases fleeting citrus esters first, followed by a pine sap resonance and sweet pepper spice. The profile is immediately distinguishable from sweeter dessert cultivars, skewing cleaner, greener, and more resinous. For consumers who prefer classic sativa aromas, Auto Haze reads as authentic and assertive.
Airtight storage at 58–62% relative humidity helps preserve the brighter volatiles over months. Over-drying below 50% RH can mute terpinolene-driven lift, while overly wet jars risk chlorophyll retention and grassy undertones. A cure of 3–6 weeks is a good baseline for optimal bouquet development.
Flavor Profile
The flavor mirrors the nose with brisk citrus and pine at the forefront, finishing with a lightly sweet incense. On inhale, expect lemon zest and resinous evergreen, with a crisp mouthfeel that avoids heaviness. On exhale, mild pepper, cedar, and a clean herbal aftertaste linger without cloying sweetness.
Vaporization at 175–190°C tends to emphasize citrus and herbal sparkle, preserving terpinolene and pinene. Higher temperatures (195–205°C) pull forward caryophyllene’s pepper and deeper wood, shifting the profile toward a warmer spice. Combustion introduces faint toast notes while still maintaining a green, resinous identity.
Flushing and curing practices have an outsized impact on flavor clarity. When dried at 18–21°C and 55–60% RH for 10–14 days, many growers report a cleaner palate and better separation of citrus and pine layers. Harshness and grassy flavors usually indicate too-fast drying or insufficient cure time.
Compared with dessert hybrids, Auto Haze is notably less sugary and more refreshing. It pairs well with coffee or tea where citrus and spice can complement the beverage’s acidity or tannin. The overall impression is bright, tidy, and energizing, with minimal palate fatigue over repeated sessions.
Cannabinoid Composition and Potency
Auto Haze generally expresses THC in the mid to upper teens, commonly ranging 14–20% under optimized indoor conditions. CBD frequently measures below 1%, placing the chemotype in a THC-dominant category typical of Haze-leaning autos. Minor cannabinoids such as CBG can register around 0.3–1.0% depending on phenotype and harvest timing.
This potency aligns with modern autoflower standards, where improvements in selection and cultivation have closed the gap with photoperiod lines. Under weaker light or nutrient stress, THC may trend toward the lower end of the range, while strong lighting and good environmental control often push toward 18–20%. Autos rarely exceed 22% THC in a repeatable fashion, and Auto Haze is no exception.
Consumers commonly report a clear, quick onset reflecting the cultivar’s sativa-forward profile. The experience is typically stimulating at lower doses and can become racy at high doses given the low CBD. For balanced results, many users aim for 5–10 mg THC per session when vaping or ingesting, titrating upward as tolerance dictates.
Harvest timing influences both perceived potency and effect contour. Pulling when most trichomes are milky with minimal amber usually preserves a zippier high, while allowing 5–10% amber can add a touch more body. That difference can be felt even when cannabinoid percentages shift only slightly, underscoring the role of minor oxidative changes in shaping effect.
Terpene Profile and Minor Aromatics
Auto Haze is typically terpinolene-forward, consistent with its Haze ancestry. In well-grown samples, total terpene content often lands around 1.0–2.0% by dry flower weight, with standouts occasionally approaching 2.5%. A representative distribution might include terpinolene at 0.3–0.8%, beta-myrcene at 0.2–0.6%, beta-caryophyllene at 0.2–0.5%, alpha-pinene at 0.1–0.3%, ocimene at 0.1–0.3%, and limonene at 0.1–0.3%.
These figures vary with growing method, light intensity, and post-harvest handling. For example, high-intensity LED lighting paired with moderate canopy temperatures can boost monoterpene retention relative to high-heat HPS environments. Conversely, fast drying or temperatures above 24°C during dry can reduce monoterpene levels noticeably, flattening the citrus-pine top notes.
In addition to the dominant terpenes, minor contributors like linalool, humulene, and eucalyptol may be detectable in trace amounts. While individually small, these compounds add floral, woody, and camphoraceous edges that round out the incense character. Caryophyllene is often the primary sesquiterpene detected, potentially adding pepper warmth and interacting with CB2 receptors.
Compared to dessert cultivars rich in limonene and linalool, Auto Haze’s terpinolene-pinene axis yields a “greener” and more resinous effect profile. Many consumers find this combination uplifting and focus-friendly, especially under daylight conditions. Growers seeking to maximize this profile should prioritize slow drying and steady RH in the cure.
Lab analyses of Haze-leaning autos frequently show terpinolene as a top peak even when total terpene content is moderate. This aligns with user-perceived aroma: sharp citrus, green pine, and sweet resin. Auto Haze fits that pattern reliably when cultivated under stable environmental conditions.
Experiential Effects and User Reports
Auto Haze is broadly reported as energizing, clear, and mentally elevating, particularly at low to moderate doses. The onset is fast when inhaled, often within 1–5 minutes, peaking around 20–30 minutes, and tapering over 2–3 hours. Users often describe an uplift in mood and motivation, with sensory brightness that pairs well with creative or outdoor activities.
At higher doses, the stimulating nature can become edgy for sensitive individuals, especially those prone to anxiety. The low CBD baseline does little to counterbalance THC’s activation, so cautious titration is advised. Some users note a mild body lightness without heavy couchlock, suggesting a modest indica contribution to comfort without sedation.
Functional use cases frequently include daytime chores, brainstorming, and social settings with active conversation. Music and exercise are common pairings, as the citrus-pine profile feels crisp and invigorating. Task switching and focus may improve for some, though others report a more diffuse, exploratory mindset consistent with sativa-leaning profiles.
Compared with heavier hybrids, Auto Haze’s comedown is relatively clean and short, reducing residual fog. Vaporization can accentuate clarity by minimizing combustion byproducts. Edible preparations shift the curve later and longer, lasting 4–6 hours, with more pronounced body effects at the tail end.
As always, user experience varies with set, setting, and tolerance. New consumers should start at 2.5–5 mg THC and evaluate after at least 60 minutes for ingestibles and 10–15 minutes for inhalation. Hydration, a light snack, and a calm environment all contribute to a steady, enjoyable session.
Potential Medical Applications and Risks
Auto Haze’s energetic profile may be useful for fatigue, low mood, and motivational deficits, particularly in the daytime. Patients seeking clearer, uplifting effects often prefer terpinolene- and pinene-forward cultivars like this one. The National Academies of Sciences, Engineering, and Medicine (2017) concluded there is substantial evidence that cannabis is effective for chronic pain in adults, though the best-suited chemotype can vary by patient.
The cultivar’s low CBD and stimulating edge may also support task engagement for some individuals with attention or mood challenges. However, those with a history of anxiety or panic may find high doses counterproductive. Small test doses are recommended to gauge sensitivity before integrating into a routine.
Patients with neuropathic discomfort sometimes report relief from THC-dominant cultivars, though sedation is minimal here compared with heavier indicas. The peppery caryophyllene content could contribute to perceived anti-inflammatory effects, as caryophyllene can interact with CB2, though clinical significance in whole-flower use remains under investigation. For headache-prone individuals, the bright terpene profile is a mixed bag—some find it relieving, others find it too stimulating.
As with all THC-dominant cannabis, risks include anxiety, elevated heart rate, short-term memory impairment, and impaired motor coordination. Those with personal or family histories of psychosis should avoid high-THC products; medical supervision is advisable in any psychiatric context. Pregnant or breastfeeding individuals should abstain from cannabis due to potential developmental risks.
This information is educational and not a substitute for tailored medical advice. Patients should consult healthcare professionals, start low, go slow, and keep a journal of dose, timing, and effects. When possible, lab-tested products with labeled cannabinoid and terpene content provide better consistency and predictability.
Comprehensive Cultivation Guide
Lifecycle and timing. Auto Haze typically completes in 70–85 days from sprout indoors, with many phenotypes ripe around day 75. Outdoors, expect 75–95 days depending on temperature and daylight length, with faster results in warm, stable climates. Autoflowering nature removes the need for a 12/12 schedule; 18–20 hours of light throughout is common for maximum growth.
Environment and lighting. Ideal day temperatures range 24–27°C with night at 18–22°C; CO₂ supplementation to 900–1,100 ppm can boost growth if PPFD exceeds 700 µmol/m²/s. Recommended PPFD is 500–700 µmol/m²/s early, ramping to 700–900 in mid-flower for experienced growers who can manage heat and nutrition. Target DLI of 35–45 mol/m²/day supports strong performance under 18–20 hours of light.
Humidity and airflow. Maintain RH at 65–75% for seedlings, 55–65% in early veg, 45–55% in mid-flower, and 40–50% late flower. Good airflow reduces microclimates and mold risk, particularly near elongated Haze colas. Two to three circulating fans per 1.2 m tent and a properly sized exhaust with carbon filtration are recommended for odor and moisture control.
Medium and containers. Autos dislike transplant shock; sow directly into final pots when possible. For soil or soilless mixes, 11–15 L containers balance root room and speed; outdoors, 20–30 L offers added thermal stability. A light, aerated mix (e.g., peat or coco with 20–30% perlite) prevents overwatering and supports rapid root expansion.
Nutrition and pH. Start seedlings at EC 0.6–0.8, increase to 1.0–1.4 in early growth, and 1.6–2.0 in peak flower, adjusting to plant response. Soil pH should sit 6.2–6.8; coco/hydro 5.8–6.2. Calcium and magnesium supplementation is often beneficial under LEDs; aim for Ca:Mg roughly 2:1 in solution.
Irrigation strategy. Water to 10–20% runoff in soilless systems to avoid salt buildup; in living soils, water more conservatively to field capacity without heavy runoff. Allow the top 2–3 cm to dry before rewatering to support oxygen exchange. Overwatering early is a common error that slows autos more than photoperiods.
Training and canopy management. Low-stress training (LST) at nodes 3–5 spreads the canopy and evens light without stalling growth. Avoid topping unless plants are exceptionally vigorous and topped very early (around day 14–18 from sprout). Defoliate lightly and selectively to open bud sites, but do not strip aggressively; aim to remove only 15–20% of foliage at a time.
Pest and disease management. Implement integrated pest management (IPM) with weekly inspections, yellow sticky cards, and prophylactic biologicals (e.g., Bacillus subtilis for foliar disease, Beauveria bassiana for insects). Keep leaf surfaces dry during lights-on to reduce botrytis risk in dense top colas. Sanitize tools and surfaces between cycles to avoid carryover of fungus gnats, thrips, or PM.
Outdoor considerations. Auto Haze thrives in full sun with daily highs of 22–30°C and low nighttime humidity. In temperate latitudes, plant after the final frost, aiming for mid-to-late spring starts to catch the warmest 75–95 day window. Expect 60–150 g per plant depending on pot size, sun hours, and nutrition consistency.
Expected yields. Indoors under modern LEDs at ~600–800 µmol/m²/s and solid environmental control, 350–500 g/m² is attainable, with 0.8–1.3 g/watt as a practical efficiency range. Single large autos can yield 70–120 g in 11–15 L pots with balanced feeding. Stress, overwatering, or heavy topping often reduces yields by 10–30% in autos.
Troubleshooting common issues. Pale new growth and interveinal chlorosis may signal magnesium deficiency, especially under LEDs—add 0.3–0.5 g/L MgSO₄ or a cal-mag supplement. Tall, lanky plants indicate insufficient PPFD or excessive blue depletion; increase light intensity gradually and consider minor LST. Foxtailing at the top colas can be heat or light-stress related; reduce canopy temps to 24–26°C and lower PPFD by 10–15%.
Irrigation data points. A vigorous plant in mid-flower in 11–15 L coco may use 1.2–2.0 L of solution per day at 50–55% RH. In soil, waterings every 2–3 days are common early, moving to every 1–2 days near peak flower, depending on pot breathability. Track pot weight to refine timing and avoid root hypoxia.
Quality optimization. Maintain canopy VPD around 1.2–1.4 kPa mid-flower to balance transpiration and stomatal conductance. Keep night temperature only 3–5°C lower than day to avoid excessive stretch and slow metabolism. Use gentle leaf tucking rather than heavy defoliation to preserve photosynthetic capacity in a compressed lifecycle.
Harvest, Curing, and Post-Processing
Harvest window. Auto Haze typically shows cloudy trichomes around days 68–78 from sprout, with 5–10% amber appearing shortly thereafter. For a brisk, uplifting effect, harvest when most trichomes are cloudy and pistils are largely oxidized but not fully receded. For a touch more body, wait for 5–10% amber trichomes before cutting.
Pre-harvest practices. Some growers perform a 24–48 hour dark period, though data on benefits is mixed. More reliably, holding canopy temperatures around 22–24°C and RH 45–50% in the final week preserves volatile terpenes while the plant finishes.
Drying parameters. Aim for 10–14 days at 18–21°C and 55–60% RH with gentle airflow—not directly on flowers. This slow dry preserves monoterpenes that would otherwise volatilize, supporting a fuller aroma and flavor. Faster drying or high heat can reduce perceived terpene complexity by 20–30%.
Curing protocol. Once stems snap and outer moisture is uniform, jar the flowers at 58–62% RH and burp daily for the first 7–10 days. After the initial week, burp every 2–3 days for another two weeks, then weekly as needed. A 3–6 week cure improves smoothness, bouquet layering, and perceived potency clarity.
Manicure and storage. Dry-trimmed Auto Haze often retains better trichomes and fewer chlorophyll notes compared with aggressive wet trimming. Store in airtight glass away from light at 15–20°C; oxidation and UV degrade THC to CBN over time. With proper storage, sensory quality remains high for 3–6 months, gradually declining thereafter.
Comparisons, Crosses, and Market Position
Auto Haze’s signature is its classic Haze aroma and bright effect packed into a short auto schedule. Compared with photoperiod Hazes that demand 12–16 weeks of flowering, Auto Haze’s 70–85 day seed-to-harvest cycle enables three to five indoor runs per year. In practice, this increases annual output and reduces per-harvest risk for small-scale growers.
Aroma-wise, Auto Haze leans resinous and citrus-pine rather than candy-sweet, contrasting with popular dessert autos. Its terpinolene-forward profile appeals to consumers seeking clarity and freshness over confectionery richness. For dispensaries, it occupies the daytime sativa slot with an approachable THC range and aromatic authenticity.
In the breeding landscape, autoflower Hazes have been utilized to add speed and sativa lift to otherwise slow or heavy lines. Genealogy references compiled by SeedFinder show “Auto Haze” cited around hybrids such as Lemon Venom (Cream of the Crop Seeds) and lines involving Sensi Star x Big Bud, demonstrating its modular use. While not every listing refers specifically to Gea Seeds’ selection, the broader category’s impact is clear.
For home growers deciding between Auto Haze and other autos, the choice hinges on desired effect and aroma. If the goal is a clean, energetic profile with pine-citrus incense and minimal couchlock, Auto Haze is a strong candidate. If heavier body relief or dessert flavors are the priority, indica-dominant or dessert terpene autos may fit better.
Overall, Auto Haze has matured from a niche curiosity into a dependable sativa-leaning auto. Its market position is sustained by ease of cultivation, credible yields, and a recognizable Haze identity. For many, it’s the fastest route to Haze-like effects without the long wait or complex light scheduling.
