Ketama Cheese Auto is an autoflowering hybrid developed by Ketama Seeds, marrying the fast, day-length–independent flowering trait of Cannabis ruderalis with the bag-appeal and punch of indica and sativa genetics. As the name implies, it leans into the classic "Cheese" family aroma while delivering a compact, quick-finishing plant suited to both indoor tents and discreet outdoor runs. Growers typically report a seed-to-harvest window of roughly 70–85 days under 18–20 hours of light, with indoor yields commonly ranging from 350–500 g/m² when dialed in.
This cultivar targets growers and consumers who want the unmistakable Cheese funk with a modern, balanced effect profile in an easy, uniform auto format. Its structure tends to remain manageable—often 60–100 cm indoors—without heavy training, making it accessible to newer cultivators. At the same time, the resin output, terpene intensity, and potency align with intermediate to advanced expectations for boutique small-batch flower.
While official laboratory certificates vary by batch and environment, most well-grown samples of autos in this class test in the mid-teens to high-teens for THC, with trace CBD and detectable minors like CBG. The terpene profile frequently skews toward myrcene, beta-caryophyllene, and humulene, backed by accents of limonene and linalool that brighten the “cheesy” core. The result is a strain that preserves heritage funk but remains adaptable and productive in modern cultivation environments.
Origins and Breeding History
Ketama Cheese Auto originated from Ketama Seeds’ autoflower program, which emphasizes stability, rapid life cycles, and strong terpene identity. To achieve an autoflowering Cheese expression, breeders typically cross a photoperiod Cheese parent to a selected ruderalis donor, then backcross and select across multiple filial generations. This process stabilizes the auto-flowering trait (controlled by a recessive locus) while retaining the volatile aroma molecules responsible for the unmistakable Cheese bouquet.
In autos, breeders often work with larger selection populations than in photoperiod projects to lock in vigor and uniformity—several hundred to a few thousand individuals per generation is not unusual. Across three to five generations, phenotypes expressing the desired internodal spacing, bud density, and terpene intensity are repeatedly selected and recombined. The result for Ketama Cheese Auto is a plant that consistently flowers irrespective of day length and that displays the characteristic Cheese nose even under the abbreviated vegetative windows of auto cultivation.
Strain makers frequently keep precise parental identities proprietary, a practice that is common across the seed industry. Databases such as SeedFinder’s genealogy index even maintain entries for “unknown” or undisclosed parent lines used broadly across the market, emphasizing how secrecy around exact parentage can be the norm. The “Original Strains Unknown Strain Lineage & Hybrids” listing is an example of how widespread, intentionally undisclosed genetics appear in modern crosses, situating Ketama Cheese Auto within a landscape where performance and phenotype often matter more than naming every ancestor.
Because the Cheese family traces back to a particularly pungent Skunk #1 phenotype selected in the UK in the late 1980s, breeders aiming at a true-to-name Cheese auto typically preserve the skunky, buttery, and slightly acrid funk that defines the original. Ruderalis donors are chosen for low stature, short internodes, and early-flowering behavior to ensure a full cycle in 10–12 weeks. Ketama Seeds’ version reflects these priorities by producing robust aroma and a compact architecture without sacrificing cycle speed.
Genetic Lineage and Architecture
By heritage, Ketama Cheese Auto is ruderalis/indica/sativa—a three-way hybrid class that blends the autonomous flowering of ruderalis with the resin density of indica and the heady uplift of sativa. In practice, many Cheese autos express an indica-leaning structure (broad leaflets, tighter node spacing) while preserving some sativa influence in the top-flower geometry and mental clarity. This duality is typical for Cheese-derived autos, delivering both a rhythmic, feel-good headspace and a comfortable body effect.
Although Ketama Seeds does not publicly release a precise pedigree, the Cheese anchor almost certainly descends from a Skunk #1–type mother line, given Cheese’s historical origin. The ruderalis component introduces the autoflowering trait and compresses the life cycle, often carrying alleles associated with environmental resilience and cold tolerance. Over multiple generations, breeders select away from the lower-potency aspects of wild ruderalis while retaining the day-neutral flowering behavior.
From a genetic architecture standpoint, autos carry homozygous recessive alleles that confer photoperiod insensitivity, enabling flowering irrespective of day length. Because this trait is recessive, breeders must ensure both parental contributions support the auto phenotype in the final seed. The stabilizing work often includes reducing variation in internode length, ensuring consistent flower initiation around week 3–5 from sprout, and maintaining terpene concentration above 1% by weight after cure.
Phenotypically, growers can expect short-to-medium height with a central cola and several productive satellite sites. Calyxes tend to be moderately sized, forming chunky, skunk-forward blooms with a calyx-to-leaf ratio around 2:1 to 3:1 in well-selected phenotypes. Resin heads commonly span 70–120 microns, with bulbous capitate-stalked trichomes dominating the surface, a visual clue to substantial terpene and cannabinoid content.
Physical Appearance and Plant Morphology
Ketama Cheese Auto typically grows to 60–100 cm indoors under 18–20 hours of light, depending on pot size, substrate, and PPFD. Outdoors in temperate climates, 70–120 cm is common during peak summer runs, with total cycle time still 70–90 days from emergence. Stems are moderately thick with good lateral branching, and the plant often presents a Christmas-tree silhouette that responds well to gentle low-stress training.
Leaves are medium to broad with a deep green hue, especially under nitrogen-sufficient regimes in early growth. Internode spacing is close, helping the plant stack flowers even when the vegetative window is short. As bloom progresses, upper fan leaves may display slight serration curling under high light, signaling the importance of managing PPFD and leaf-surface temperature.
Buds develop into dense, slightly conic clusters with a sugared frosting of trichomes and visibly swollen pistillate calyxes. Under cooler night temperatures (16–18°C), some phenos show anthocyanin blush in sugar leaves, though full purple flowers are less common. Mature stigmas transition from white to orange-brown, and trichomes shift from clear to cloudy with a sprinkling of amber near harvest.
Trim quality is favorable thanks to a decent calyx-to-leaf ratio, allowing for a faster hand trim than leafier autos. Wet-to-dry shrinkage of 70–78% is typical, so a 400 g fresh yield will often cure down to 88–120 g of finished flower. The finished buds retain the signature Cheese funk, often discernible even through jars and bags after a proper cure.
Aroma Profile
Aromatically, Ketama Cheese Auto pays homage to its namesake with a pungent, dairy-funk nose supported by earthy skunk and faintly sweet fruit. The initial impression often includes a buttery, tangy note reminiscent of aged cheddar, underpinned by volatile sulfur compounds and short-chain acids that give Cheese its unmistakable punch. Supporting tones include damp earth, spice, and a hint of lemon peel, especially in phenos with limonene spikes.
Myrcene and beta-caryophyllene set the baseline, giving the strain a musky, resinous heart with peppery edges. Humulene contributes a dry, hoppy nuance, while linalool can add a soft floral thread in certain plants. A slight acrid edge on the back end—classic Skunk heritage—often becomes pronounced when the flowers are warmed in the grinder.
Aroma intensity tends to be high, with many growers reporting room-filling scent during weeks 6–10 from sprout. Carbon filtration becomes essential indoors; a 6-inch carbon filter paired with 400–600 m³/h extraction is commonly sufficient for a 1–1.2 m² tent. Proper curing at 60–62% relative humidity for 3–6 weeks preserves the richer “cheese rind” complexity and keeps the citrus-mineral top notes intact.
During late cure, the bouquet deepens, and the initial sharpness rounds into a balanced funk that reads both savory and subtly sweet. Over-drying below 55% RH can flatten the aroma, so slow-dry protocols help retain terpene mass. When ground, the bouquet often explodes with a layered mix of buttered toast, pepper, and faint tropical fruit.
Flavor Profile
On the palate, Ketama Cheese Auto delivers classic Cheese flavors: a creamy, tangy start with a savory, skunky core and a peppered finish. The smoke is medium-bodied and can feel plush when cured correctly, coating the tongue with a buttery echo. Retrohale amplifies the pepper-spice from beta-caryophyllene and humulene, while a subtle lemon or green-apple snap sometimes flickers on the exhale.
Vaporization at 175–185°C accentuates sweetness and trims harshness, bringing forward linalool’s floral tone and limonene’s zest. Higher temperatures (195–205°C) intensify the spicy, resinous elements and can feel more sedative due to the broader volatilization spectrum. In joints, the flavor stays robust through the midpoint, often finishing with a toasty, nutty character.
Proper post-harvest handling is critical to flavor fidelity. A slow dry of 10–14 days at 18–20°C and 58–62% RH minimizes terpene loss and prevents chlorophyll bite. After a 3–6 week cure with periodic burping, most jars show a measurable increase in perceived sweetness and a smoother finish, which sensory panels commonly associate with improved smokeability.
Water activity (aw) in the 0.58–0.62 range supports stable, flavorful storage while limiting microbial risk. At this equilibrium, total terpene content tends to decline more slowly than at higher aw values, preserving the nuanced dairy-funk blend. Light exposure remains a major flavor killer, so opaque containers preserve the taste profile over time.
Cannabinoid Composition
Autoflowering Cheese-type hybrids commonly test between 15–20% THC when grown under optimized indoor conditions, and Ketama Cheese Auto generally aligns with this band. Outdoor and lower-intensity indoor grows often land in the 12–16% THC range due to reduced PPFD and environmental variability. CBD is usually low (<1%), while minors like CBG can reach 0.3–1.0% and CBC 0.1–0.5%, depending on phenotype and harvest timing.
Cannabinoid accumulation correlates with light intensity and nutrient availability, with peak synthesis typically occurring as trichomes transition from clear to cloudy. Harvesting at predominantly cloudy with 10–20% amber often yields the highest perceived potency without excessive sedative drift. Delaying harvest further can increase CBN levels slightly through THC oxidation, which some users experience as more narcotic.
Post-harvest handling materially affects lab outcomes. Published storage studies have shown that THC can degrade by roughly 10–20% over 12 months at room temperature in light-exposed conditions, while cool, dark storage slows this decline significantly. Total terpene content can drop by 30–50% in the first 6 months if stored warm and exposed to air, underscoring the value of airtight, lightproof containers.
For extractors, Ketama Cheese Auto’s resin head size and density can support 15–22% returns in hydrocarbon extraction from quality indoor material, with lower yields in rosin pressing unless flowers are exceptionally resinous. Because terpenes are a meaningful fraction of the mass, fresh-frozen runs often deliver a louder Cheese expression than cured runs. As always, individual batches vary, and only a certificate of analysis can confirm exact numbers.
Terpene Profile
The terpene baseline in Ketama Cheese Auto tends to be myrcene-dominant, often accompanied by significant beta-caryophyllene and humulene. Total terpene content in well-cultivated autos frequently lands between 1.0–2.5% by dry weight, with standout phenos surpassing 3.0% under ideal conditions. Myrcene commonly ranges from 0.4–1.2%, beta-caryophyllene 0.2–0.8%, and humulene 0.1–0.4%.
Limonene and linalool appear as secondary components, shaping the fruit-citrus lift and floral softness that keeps the “cheese” from becoming one-note. Trace terpenes such as ocimene, terpinolene, and bisabolol sometimes register in the 0.02–0.10% range, subtly augmenting freshness and sweetness. When limonene rises above ~0.2%, users often report a brighter top note and a more upbeat onset.
From a pharmacological perspective, beta-caryophyllene is unique as a dietary cannabinoid and CB2 agonist, implicated in anti-inflammatory signaling in preclinical models. Myrcene has been associated with sedative and muscle-relaxant qualities, particularly when combined with THC. Linalool is studied for anxiolytic potential, while humulene is explored for anti-inflammatory and appetite-modulating properties in preliminary research.
Cultivation practices strongly influence terpene expression. High PPFD with proper vapor-pressure deficit (VPD) support, moderate nitrogen in late flower, and cool finishing temperatures (18–20°C nights) are associated with higher terpene retention. Overly aggressive drying, excessive defoliation late in flower, or high heat can substantially flatten the profile.
Experiential Effects
Consumers generally describe Ketama Cheese Auto as a balanced hybrid experience that starts with an uplifted, social headspace and settles into a comfortable body ease. The onset is fairly quick—often within 5–10 minutes when inhaled—peaking around 30–45 minutes and tapering over 2–3 hours. At moderate doses (5–10 mg THC inhaled), many users report mood elevation, sensory enhancement for music and food, and light-to-moderate muscle relaxation.
At higher doses, the indica component becomes more prominent, introducing heavier eyelids and a stronger couchlock tendency, especially in evening settings. The sativa influence maintains enough clarity to prevent muddiness for many users, though THC-sensitive individuals should start low to avoid racy or anxious edges. Dry mouth and red eyes are the most common minor side effects, with occasional transient dizziness reported when overconsumed.
Compared to sharp, citrus-dominant hybrids, the Cheese family may feel a touch more grounding and savory. For daytime use, microdosing (1–3 puffs or 2.5–5 mg THC) can preserve functional clarity while offering mood support. In social environments, its pungent aroma can be conspicuous; vaporizers at 175–185°C reduce smell and preserve an energetic flavor.
Tolerance dynamics mirror other mid-to-high THC strains. Regular users may find 10–20 mg inhaled appropriate for full effects, while new users often thrive at 3–7 mg. Spacing sessions, staying hydrated, and pairing with food can smooth the ride and extend the pleasant window.
Potential Medical Applications
With a THC-forward chemotype and a terpene ensemble led by myrcene and beta-caryophyllene, Ketama Cheese Auto maps to several potential therapeutic domains. Anecdotally, many patients report relief around stress, mood, and generalized discomfort, consistent with survey data showing cannabis users frequently cite anxiety, pain, and insomnia as top reasons for use. THC’s analgesic and appetite-stimulating properties, combined with caryophyllene’s CB2 activity, make this profile interesting for inflammatory pain phenotypes in preclinical contexts.
Myrcene’s sedative synergy with THC may help with sleep onset at moderate-to-higher doses, especially when harvested with a touch of amber trichomes. Limonene and linalool have been studied for mood-supportive and anxiolytic signals in animal and limited human studies, though responses vary widely. Individuals with THC sensitivity or panic-prone tendencies should start at very low doses and consider vaporization at lower temperatures to minimize intensity.
In neuropathic pain contexts, evidence for THC-rich formulations shows mixed but promising patient-reported outcomes, with some surveys indicating 50–70% of respondents experiencing meaningful symptom reductions. However, controlled clinical trials are still developing in scope and often use standardized extracts rather than whole-flower chemovars. As with all cannabis use, titration and journaling can help match dose and time-of-day to symptom patterns.
This information is educational and not medical advice. Patients should consult qualified healthcare professionals, especially if they take medications metabolized by CYP450 enzymes that THC and terpenes may influence. Legal access and product consistency vary by jurisdiction, so lab-tested products and consistent dosing are crucial for medical experimentation.
Comprehensive Cultivation Guide
Lifecycle and Scheduling
Ketama Cheese Auto completes its life cycle in approximately 70–85 days from germination under 18–20 hours of daily light. Flower initiation typically begins around days 18–28, with visible pistils forming in week 3–4 from emergence. Because autos are time-bound rather than photoperiod-bound, any major stress in weeks 2–5 can noticeably reduce final yield. Planning the environment to be dialed from day one is vital, as there is minimal time to recover from setbacks.
Lighting and DLI
For indoor growing, target 600–800 µmol/m²/s PPFD in mid-flower without supplemental CO₂, with daily light integral (DLI) in the 35–45 mol/m²/day range. Many growers run 18/6 lighting throughout; some push 20/4 to gain a slight biomass increase without sacrificing plant rest. Light saturation for autos often occurs around 900–1000 µmol/m²/s without CO₂—pushing beyond can cause photoinhibition or require more aggressive feeding and environmental support.
Environment and VPD
Ideal canopy temperatures are 24–26°C day and 20–22°C night in early-to-mid growth, tapering to 22–24°C day and 18–20°C night in late flower to preserve terpenes. Relative humidity targets by stage are roughly 65–70% (seedling), 55–65% (early veg/transition), and 45–55% (flower), with a VPD of 0.9–1.2 kPa during bloom. Leaf-surface temperature should be monitored; if it runs 1–2°C above ambient under LEDs, slightly lowering intensity or increasing airflow can help.
Mediums, Containers, and pH/EC
Autos prefer being sown directly into their final pot to avoid transplant shock during the short veg phase. Container sizes of 11–19 L (3–5 gallons) are common indoors; outdoors, 20–30 L gives a buffer against heat and watering variability. Target pH of 6.3–6.7 in soil and 5.7–6.1 in coco/hydro, with feed strength peaking around 1.4–1.8 mS/cm EC (700–900 ppm on a 500 scale) in mid-bloom.
Nutrition Strategy
Provide a balanced vegetative feed in weeks 1–3 that emphasizes nitrogen but avoids excess that can delay flower stacking. Transition to a bloom formulation by week 3–4 as pistils appear, elevating phosphorus and potassium while keeping calcium and magnesium steady. Many autos respond well to N tapering after week 5, which reduces leafiness and promotes denser, terpene-rich flowers.
Irrigation
In soil, water to 10–20% runoff once the top 2–3 cm of medium dries; in coco, more frequent irrigations with lower volumes maintain stable EC and oxygenation. Overwatering early is a common yield killer—seedlings do best with a modest wet-dry cycle to encourage root exploration. As biomass increases, daily irrigation is often necessary, with 4–6% of container volume per event being a helpful starting point.
Training and Canopy Management
Low-stress training (LST) works best for Ketama Cheese Auto—gently bending the main stem in days 12–20 opens side branches and evens the canopy. Avoid topping after day 14–18 to prevent growth delays; many growers skip topping entirely with autos. Strategic defoliation can help airflow, but heavy leaf removal after week 4 can reduce energy capture and lower yields.
Pest and Disease Prevention
Integrated pest management (IPM) begins before sprout: clean spaces, sticky cards, and quarantining any new plant material. Maintain vigorous airflow and avoid RH spikes at lights-off to reduce botrytis risk in dense Cheese-style blooms. Biological controls like Bacillus subtilis for foliar pathogens and predatory mites for common pests (e.g., Phytoseiulus for spider mites) create a safety net.
CO₂ and Advanced Control
If enriching CO₂ to 900–1200 ppm, you can support PPFD up to 1000–1200 µmol/m²/s and increase growth rate, but only if nutrition, VPD, and root-zone oxygen are aligned. Without tight control, CO₂ rarely benefits autos as much as photoperiods, and the short veg window limits the upside. For many small tents, dialing fundamentals (light, VPD, feed) yields better ROI than CO₂.
Expected Performance and Benchmarks
Indoors under optimized LED lighting, yields of 350–500 g/m² are common across 70–85 days from seed. Outdoors, single-plant yields of 40–120 g are typical depending on season length and DLI, with mid-summer plantings outperforming shoulder-season runs. Bud density scores are generally medium-high, with good bag appeal after a slow dry and cure.
Harvest Timing
Track maturity via trichomes: a sweet spot for balanced effects is mostly cloudy with 10–20% amber. Harvesting earlier at mostly cloudy delivers a brighter, more energetic profile; later amber increases sedative qualities. In many environments, this point arrives between days 70 and 85 from sprout, though cooler grows may run slightly longer.
Flushing and Finishing
In inert media like coco, a 7–10 day low-EC finish helps reduce residual salts and improve burn. In living soil, avoid aggressive flushing; instead, taper feeds and provide plain water to allow natural nutrient drawdown. Finishing temperatures at 18–20°C night and 45–50% RH can enhance terpene retention and color.
Drying and Curing
Aim for a 10–14 day dry at 18–20°C and 58–62% RH with gentle airflow, keeping buds in the 0.58–0.62 water-activity range. After bucking and jarring, cure for 3–6 weeks, burping jars initially daily and then weekly as moisture equilibrates. Properly cured Ketama Cheese Auto maintains a loud aroma and smooth smoke, with measurable terpene preservation compared to fast-dry methods.
Common Pitfalls and Fixes
Overfeeding nitrogen in weeks 3–6 can yield leafy, harsher buds; watch for dark, clawing leaves and taper N if seen. Excess PPFD without adequate calcium and magnesium can cause interveinal chlorosis and tip burn—raise calcium to 150–180 ppm and magnesium to 50–70 ppm in coco/hydro. Over-defoliation after week 4 reduces photosynthate and can cut yields by 10–20%—keep removal purposeful and limited.
Strain-Specific Notes
The Cheese lineage’s pungency necessitates robust odor control—use an appropriately sized carbon filter and maintain negative pressure. Compared to ultra-vigorous sativa-leaning autos, Ketama Cheese Auto’s moderate stretch makes it forgiving in small tents and cabinets. Because autos are genetically anchored to a schedule, consistent early care (stable VPD, appropriate PPFD, no transplant shock) produces the most reliable outcomes across runs.
