Auto Blue Cheese is a compact, flavor-forward autoflower that blends the dessert-like sweetness of Blueberry with the savory funk of UK Cheese, then overlays the rapid, daylength-independent flowering of ruderalis. Bred by Divine Seeds, this cultivar preserves the signature Blue Cheese aroma while finishing quickly and staying manageable in tight spaces. As a ruderalis/indica/sativa hybrid, it balances relaxing body effects with clear-headed mood elevation when grown and cured correctly.
Growers value Auto Blue Cheese for its accelerated seed-to-harvest timeline and solid yields relative to its size. Comparable Blue Cheese autoflower lines have been documented to complete a cycle in roughly 8–10 weeks from germination, with Royal Queen Seeds listing about 10 weeks for similar genetics. In practice, phenotypes typically cluster around 70–77 days, with environmental control playing a decisive role.
Consumers gravitate toward its blueberry cheesecake flavor layered over a savory, earthy base. The terpene backbone is usually myrcene-dominant—like photoperiod Blue Cheese—supported by limonene and beta-caryophyllene for a sweet-citrus lift and peppery depth. Potency generally lands in the mid-to-high teens for THC with low CBD, offering a versatile profile for evening relaxation or creative downtime.
History
The Blue Cheese lineage began with a cross of DJ Short’s Blueberry and the UK Cheese cut, a standout skunk phenotype prized since the late 1980s for its pungency and yield. That photoperiod hybrid cemented its reputation in the 2000s for combining berry-forward sweetness with a savory, cheddar-like bite. As autoflower breeding matured in the late 2000s and early 2010s, breeders began infusing ruderalis genetics to deliver faster cycles and compact frames.
Divine Seeds’ Auto Blue Cheese follows this trajectory by stabilizing the Blue Cheese flavor and resin traits while embedding the autoflowering allele. Multiple generations of selection are required to fix autoflowering consistently, typically involving at least F4–F6 stabilization to minimize photoperiod reversion. The result is a dependable auto that retains the parent profile yet adapts to short seasons and indoor perpetual cycles.
The market’s expectations for autoflowers have changed markedly over the last decade, with THC levels rising and yields improving year-over-year. Where early autos often tested below 12% THC, modern autos like Cheese-derived lines commonly reach 15–20% THC. This shift aligns with improved ruderalis introgression strategies that preserve chemotype while enhancing vigor and uniformity.
Genetic Lineage
Auto Blue Cheese is a three-way composite of ruderalis, indica, and sativa genetics, with an indica-forward phenotype inherited from Blueberry x UK Cheese. Blueberry contributes sweet berry terpenes, anthocyanin coloration potential, and a calm, body-centric effect. UK Cheese transmits the hallmark funky, earthy, and slightly acidic aroma with robust yield structure and dense buds.
The ruderalis contribution is primarily functional, conferring daylength-independent flowering and compressing the life cycle into roughly 8–10 weeks. Ruderalis alleles also reduce plant stature and often enhance early vigor and cold resilience. While ruderalis alone tends to dilute THC, careful backcrossing restores potency to modern auto standards.
Practically, the phenotype leans hybrid-indica in structure: medium internodal spacing, broad leaflets early on, and a stout central cola supported by satellite branches. The sativa influence softens the sedation and adds a mild cognitive uplift, preventing the stone from becoming immobilizing. This balance makes Auto Blue Cheese appropriate for late afternoon through evening without completely flattening motivation.
Appearance
Auto Blue Cheese plants are typically compact, finishing at 60–100 cm indoors and 70–120 cm outdoors under optimal conditions. The architecture favors a dominant main cola with 6–10 productive side branches, especially when trained early with gentle low-stress techniques. Internodes are moderately tight, supporting stacked floral clusters that merge into colas during late bloom.
Foliage starts broad and dark green, then may display purple or violet accents as temperatures drop below 20°C at night in late flower. Anthocyanin expression is most pronounced in phenotypes that lean toward the Blueberry parent, especially if day-night temperature differentials exceed 5–7°C. Calyxes swell into teardrop shapes coated in a dense frosting of capitate-stalked trichomes.
Mature buds are medium density to very dense depending on light intensity, with a high calyx-to-leaf ratio that streamlines trimming. Pistils transition from cream to orange and rust as harvest nears, with 10–15% amber trichomes usually signaling peak potency for a balanced effect. The finished flowers often show a blue-green cast under natural light and a silvery sheen under LED due to heavy resin coverage.
Aroma
The fragrance opens with a distinct blueberry jam and cream note that reads immediately as Blue Cheese to experienced noses. Underneath, a tangy, savory funk evokes aged cheddar or cave-aged cheese, lending a uniquely appetizing contrast. Earthy, damp forest floor notes round the finish and become more pronounced as the flowers dry and cure.
Myrcene is often the most abundant terpene in Blue Cheese lines, with Leafly listing myrcene as dominant followed by limonene and caryophyllene in Blue Cheese. That hierarchy generally carries into Auto Blue Cheese, though environmental stress, drying parameters, and cure length can shift ratios slightly. A week 7–9 bouquet tends to be loudest, especially if relative humidity is kept in the 45–50% range to prevent terpene volatilization.
Grinding the flower amplifies the savory component and releases a citrus peel lift from limonene that brightens the profile. In jars, the top note is sweet and fruity, but the nose evolves toward spicier, peppery caryophyllene after 4–6 weeks of curing. Terpene intensity is typically above average for autos when grown under moderate PPFD with consistent nutrition and proper dry-room management.
Flavor
On inhalation, the flavor leads with sweet blueberry and vanilla cream, akin to a blueberry cheesecake or custard. As the vapor or smoke coats the palate, a lactic tang and skunky earth emerge that clearly signal the Cheese parentage. The exhale finishes with cracked black pepper and a subtle lemon-zest lift.
Vaporization at lower temperatures in the 175–185°C range tends to emphasize berry esters and a soft sweetness. Raising the temperature toward 195–205°C coaxes out the earthy, spicy caryophyllene and humulene components for a more savory impression. Combustion imparts a toasty, nutty edge that some describe as graham crust, especially in well-cured samples.
Proper curing is central to retaining the confectionary aspect of the flavor. Target a slow dry of 10–14 days at 18–20°C and 55–60% RH, followed by jar curing at 58–62% RH for at least 3–4 weeks. This schedule preserves the top notes and rounds the cheese-forward midrange into a more dessert-like harmony.
Cannabinoid Profile
Auto Blue Cheese commonly tests in the mid-to-high teens for THC, aligning with Cheese-derived autos listed at 15–20% THC and 0–1% CBD by multiple vendors. SeedSupreme lists Cheese Autoflower at high THC (15–20%) with low CBD (0–1%), which is a realistic expectation range for modern autos in this lineage. Blue Cheese photoperiods frequently sit around the mid-teens to high teens, and autos have largely closed the gap.
Minor cannabinoids appear in trace-to-moderate amounts depending on phenotype and harvest timing. CBG is often present at 0.2–1.0%, and CBC typically falls between 0.1–0.3% in cured flower. These minor constituents may subtly modulate the subjective effect, especially in synergy with beta-caryophyllene.
The THC:CBD ratio is usually greater than 20:1, confirming a THC-dominant chemotype. Harvest timing can tilt the experience: earlier pulls with mostly cloudy trichomes deliver a brighter, more uplifting effect, while later pulls with 10–20% amber enhance body relaxation. Growers seeking maximum potency and flavor should target a harvest window when most trichomes are cloudy with limited amber for a balanced profile.
Terpene Profile
The terpene profile mirrors classic Blue Cheese patterns, with myrcene typically leading, followed by limonene and beta-caryophyllene. Leafly lists this order for Blue Cheese, and it remains a reliable guidepost for Auto Blue Cheese grown under common conditions. Total terpene concentration in well-grown autos often ranges from 1.0–2.0% of dry weight, though standout phenotypes can exceed this under ideal post-harvest handling.
Myrcene contributes musky, fruity, and herbal tones that reinforce blueberry and earth. Limonene adds a citrus lift that brightens the top end and can impart a cleaner finish on the palate. Beta-caryophyllene brings peppery spice and is notable for acting as a CB2 receptor agonist, which may have anti-inflammatory implications in preclinical research.
Secondary terpenes typically include humulene, linalool, and alpha-pinene in smaller quantities. Humulene can enhance the woody, hoppy undertone, while linalool adds a floral lavender thread detectable at lower vaping temperatures. Alpha-pinene introduces a faint pine snap that supports mental clarity, tempering the sedative potential of myrcene-rich chemotypes.
Experiential Effects
Auto Blue Cheese tends to produce a layered effect that begins with a gentle head lift and evolves into a warm body relaxation. Onset is usually felt within 5–10 minutes when inhaled, reaching peak intensity around 30–45 minutes. The duration commonly spans 2–3 hours for most users, with a soft landing that encourages calm.
Psychologically, the mood lift can be pronounced yet tranquil, making it suitable for decompression after work or creative tinkering at home. Many find the strain conducive to music listening, cooking, or low-intensity socializing where conversation flows without jitter. The sativa contribution keeps the experience clear enough to follow a plot or game, even while the body mellows.
Physically, muscle tension tends to release gradually, especially in the neck, shoulders, and lower back. Appetite stimulation is common, aligning with the strain’s savory-sweet nose that primes the senses. Dry mouth and dry eyes are typical side effects, and inexperienced users may feel couchlock at higher doses, particularly late in the evening.
Potential Medical Uses
The THC-forward profile, with supporting myrcene and beta-caryophyllene, suggests potential utility for stress relief and pain modulation. Beta-caryophyllene’s CB2 receptor activity has been studied for its anti-inflammatory and analgesic potential, albeit mostly in preclinical settings. In practice, users report relief from tension, mild neuropathic discomfort, and stress-related somatic symptoms.
For mood, the balanced uplift without raciness can be helpful for transient anxiety, rumination, or low mood in the evening. The absence of strong stimulation makes it approachable for those sensitive to jittery sativa effects. Myrcene-rich chemotypes often aid sleep latency at higher doses, making Auto Blue Cheese a candidate for winding down before bed.
Appetite support is another plausible use, given frequent reports of munchies from Cheese-derived lines. Patients should start low and go slow, as THC can exacerbate anxiety in some individuals, particularly above personal tolerance thresholds. As always, medical use should be discussed with a qualified clinician, and individuals should avoid combining with sedatives or alcohol until they understand their response.
Comprehensive Cultivation Guide
Auto Blue Cheese rewards careful planning with swift, reliable harvests from seed. Start with viable, fresh seeds and expect germination rates of 90% or higher from reputable sources when using standard methods. A simple paper towel technique at 24–26°C with 95–100% humidity often results in taproot emergence within 24–72 hours.
Transplant shock can slow autos, so many growers plant directly into their final container. A 2–3 gallon (7.5–11 L) fabric pot is ideal for indoor runs, while 3–5 gallons (11–19 L) work well outdoors or in greenhouses. Fabric pots support air pruning and aerobic root health, which autos particularly appreciate for maintaining fast growth rates.
Use a light, well-aerated substrate with 25–35% perlite or pumice and, if desired, 10–20% coco coir blended into peat-based mixes. For living soil, build a modest, balanced mix to avoid overfertilization early; autos prefer a mild nutrient profile in weeks 1–3. Target soil pH at 6.2–6.8; in hydro or coco, maintain 5.8–6.2 for optimal nutrient uptake.
Lighting drives yield more than almost any other variable for autos. Maintain 18/6 or 20/4 light cycles from sprout to finish; both schedules are effective, with 20/4 sometimes delivering slightly faster development. Aim for a PPFD of 300–400 µmol/m²/s in days 1–10, 500–700 in weeks 2–4, and 700–900 through bloom if CO2 is ambient; this typically equates to a daily light integral of 30–40 mol/m²/day.
Environmental control stabilizes resin and terpene expression. Keep temperatures around 24–26°C day and 20–22°C night during most of the cycle. Relative humidity should track 65–70% in early vegetative growth (VPD near 0.8–1.0 kPa), 50–60% mid bloom (1.1–1.3 kPa), and 45–50% late bloom (1.3–1.5 kPa) to minimize botrytis risk in dense colas.
Nutrition should be gentle at first and responsive thereafter. Start with 0.8–1.0 EC in week 2, rising to 1.2–1.4 EC by week 3 as the plant accelerates. Peak feeding often lands in the 1.6–1.8 EC range during weeks 5–7, tapering to 1.2–1.4 EC in the final 10–14 days; always read the leaves and runoff to avoid salt buildup.
Provide nitrogen early but shift toward phosphorus, potassium, and micronutrients by week 4 when pistils appear. Calcium and magnesium support is crucial under LED lighting; supplement 100–150 ppm Ca and 40–60 ppm Mg if using RO or soft water. Maintain runoff pH within target ranges to prevent lockout and watch for telltale signs like interveinal chlorosis (Mg) or tip burn (excess salts).
Auto Blue Cheese responds very well to low-stress training that spreads the canopy without delaying growth. Begin LST by days 10–14, gently bending the main stem and securing with soft ties to encourage lateral branching. Avoid topping after day 18–20, as recovery time can cut into yield; if topping is desired, do it once at node 3–4 by day 14–16, followed by careful aftercare.
Water thoroughly but infrequently in soil: saturate until 10–15% runoff, then wait for the top 2–3 cm to dry before the next irrigation. In coco, adopt a higher-frequency, lower-volume approach to maintain 20–30% runoff and stable root-zone EC. Typical peak water uptake for a mature auto in 3-gallon fabric pots is 1.5–2.5 liters per day under 700–900 PPFD and 24–26°C.
Expect seed-to-harvest in about 70–77 days under dialed indoor conditions, though some plants may finish faster. Industry sources for comparable Blue Cheese autos cite approximately 8–10 weeks from germination to harvest, with Royal Queen Seeds listing around 10 weeks and other guides noting 8–10 weeks of flowering for Cheese autos. Outdoors, cooler nights or suboptimal DLI may stretch timelines by 7–10 days.
Yield scales with light, pot size, and training. Indoors, 350–500 g/m² is achievable with efficient LEDs, strong environmental control, and 6–10 plants per square meter in 2–3 gallon pots. Outdoors, single-plant yields of 50–150 g are common for autos in temperate climates, with 150–250 g possible in high-sun, low-stress environments.
Integrated pest management should be proactive. Maintain clean intakes, use sticky cards to monitor fungus gnats and whiteflies, and consider weekly neem or essential-oil-based sprays in vegetative stages if local pressure is high. Discontinue foliar applications once pistils cluster to prevent residue on flowers; instead, emphasize canopy airflow with 0.5–1.0 m/s gentle movement across tops.
Finish strong by managing the final two weeks as a flavor-focused phase. Lower nitrogen to near-zero, maintain stable potassium and moderate phosphorus, and avoid drastic environmental swings. Some growers drop night temps to 18–19°C in the final week to encourage color expression if the phenotype has Blueberry anthocyanin potential.
Harvest at peak ripeness by inspecting trichomes with 60–100x magnification. For a balanced effect, target mostly cloudy with 10–15% amber; for a heavier body effect, allow 15–25% amber. Immediately transition to a controlled dry room at 18–20°C and 55–60% RH with indirect airflow for 10–14 days before trimming and curing.
Yield and Performance Metrics
Under optimized indoor conditions using full-spectrum LED lighting and steady 18/6 or 20/4 schedules, Auto Blue Cheese can deliver 350–500 g/m². This assumes PPFD in the 700–900 µmol/m²/s range, VPD in the 1.1–1.4 kPa lane during bloom, and well-managed nutrition peaking around 1.6–1.8 EC. Without training or with lower light intensity, yields commonly fall in the 250–350 g/m² band.
Outdoor yields depend on latitude, season, and pot size. In temperate zones with at least 12–14 hours of strong sun and a well-prepared 3–5 gallon fabric pot, 80–150 g per plant is typical, with exceptional sites pushing beyond 200 g. At higher latitudes, the rapid finish allows two successive runs between late spring and early autumn, boosting annual output per square meter.
Cycle time efficiency is a major advantage of this auto lineage. Comparable Blue Cheese autoflowers are cited at roughly 8–10 weeks seed-to-harvest by multiple sources, which enables perpetual indoor rotations. A grower can stage new seeds every 3–4 weeks to maintain a continuous harvest cadence with overlapping phases.
Harvest, Drying, and Curing
Plan harvest timing around the target effect. Pulling at mostly cloudy trichomes retains a brighter, more functional experience, while a higher amber percentage deepens sedation and body melt. Most growers find the sweet spot with 10–15% amber and vivid terpene intensity.
Dry in a dark room at 18–20°C and 55–60% RH with gentle, indirect airflow moving under and around the hanging branches. Aim for 10–14 days of drying until small stems snap rather than bend; this slower dry retains more myrcene and limonene by limiting volatilization. Avoid fans blowing directly on the flowers, which can overdry and mute the top notes.
Cure in airtight glass jars at 58–62% RH, burping once or twice daily for the first week and then weekly thereafter. Over 3–6 weeks, the cheese-forward midrange integrates with the blueberry top note, yielding a balanced dessert-funk profile. Properly cured flowers maintain terpene intensity for months if stored at 16–18°C in a dark space.
Common Pitfalls and Troubleshooting
Overfeeding early is a frequent mistake with autos, including Auto Blue Cheese. Signs include dark, clawed leaves by week 2–3 and slow growth, which can permanently cap yield due to the short lifecycle. Start light, increase EC gradually, and monitor runoff EC to avoid salt accumulation.
Aggressive high-stress training past day 18–20 often reduces final output. Topping or heavy defoliation late can redirect energy to repair rather than flower production, losing precious days in a 70–77 day cycle. Instead, rely on early LST and selective leaf tucking to shape the canopy.
Humidity neglect in mid-to-late bloom can lead to botrytis in dense colas. Keep RH at 45–50% from week 6 onward and maintain steady airflow through and above the canopy. If local pressures are high, consider preventative biologicals like Bacillus subtilis or Serenade early in flower, discontinuing sprays as buds consolidate.
Context and Sources Integrated
This profile integrates breeder and market context specific to Auto Blue Cheese while drawing on verified characteristics of Blue Cheese and Cheese autos. Auto Blue Cheese is bred by Divine Seeds and expresses a ruderalis/indica/sativa heritage consistent with its fast lifecycle and balanced effects.
