KC 36 is a hybrid cannabis cultivar bred by KC Brains Holland, a Dutch seed company known for hardy, outdoor-capable genetics. The strain carries indica and sativa heritage, blending compact structure and resin output with a balanced, head-and-body effect profile. Public consumer reports, including Leafly listings, commonly describe KC 36 as sleepy, euphoric, and uplifted, with dry mouth, dry eyes, and occasional paranoia noted as negatives.
Growers tend to prize KC 36 for its reliable flowering window and mold resilience in temperate, sometimes damp climates. It is often selected by cultivators seeking a fast, manageable plant that can finish before prolonged autumn rains in northern latitudes. For consumers, the strain’s effect balance and approachable potency window make it a versatile evening option.
While KC Brains does not widely publicize the precise parentage, KC 36 exhibits hallmarks of indica-leaning structure with hybrid vigor. Dense, resin-rich flowers and a sweet-citrus-and-earth terpene signature are frequently reported. Its popularity is sustained by dependable yields and a forgiving cultivation curve that suits both newer and experienced growers.
History and Breeding Background
KC Brains Holland established itself in the 1990s by curating robust strains that perform well across Europe’s variable climates. The breeder’s catalog often features crosses designed to finish early outdoors while retaining potency, a trait prized by growers from the Netherlands to the UK and Central Europe. KC 36 fits into this ethos, delivering a balanced hybrid profile with practical finishing times.
The strain was introduced as part of a wave of accessible hybrids that aimed to provide consistent results without excessive indoor specialization. In the era when indoor HID lighting was dominant, KC Brains lines such as KC 33, KC 36, and related hybrids offered a reliable option for balcony and guerrilla growers. KC 36’s reputation for resilience and finish-time predictability helped it gain adoption among hobbyists and small-scale cultivators.
Open-source documentation about exact parent lines for KC 36 remains sparse, which is common for older European hybrids. Nonetheless, its morphology and terpene output suggest influence from resin-heavy indica sources and potentially a citrus-forward sativa parent. This aligns with the strain’s balanced effect reports and its utility as an evening-leaning, yet not overwhelmingly sedative, hybrid.
Genetic Lineage and Phenotypic Expectations
KC 36’s published heritage is indica and sativa, placing it in the hybrid category with a phenotype that can lean slightly indica in structure. Without an official breeder disclosure of parent cultivars, growers infer lineage based on growth traits like stout branching, medium internode spacing, and dense, frost-heavy buds. These features often reflect Afghani or similar indica ancestries.
At the same time, the aromatic spectrum and uplifted mood reports hint at sativa-leaning terpenes such as limonene and pinene in meaningful amounts. Many growers report two general phenotypes: one shorter and earlier-finishing plant with chunkier colas, and one slightly taller, more open-structured plant that stretches 20 to 40 percent into flower. Both phenotypes remain manageable indoors and responsive to training.
Phenotypic variance is typical in hybrid seed lines, and KC 36 is no exception. Selection for uniformity within the first run can lock in the desired plant architecture in subsequent clones. For most home growers, this means picking a mother plant that best matches canopy goals, whether that is a single dominant cola or a multi-top screen of green.
Appearance and Morphology
KC 36 produces dense, olive-to-forest-green flowers with tightly stacked calyxes and a generous trichome blanket. Pistils begin vibrant orange to tangerine and can mature to a deeper burnt orange by late flower. In cool night temperatures, some phenotypes show subtle anthocyanin expression, resulting in faint purples near sugar leaves.
The strain tends to develop a prominent central cola when left untopped, alongside sturdy secondary branches. Average indoor height ranges from roughly 80 to 140 centimeters, while outdoor plants can reach 150 to 220 centimeters depending on soil volume and season length. Internode spacing is moderate, helping create compact, resin-heavy flower sites that appeal to hash makers.
Leaf morphology leans toward medium-width leaflets, thicker than many sativa-dominant lines but not as broad as pure indicas. Buds often cure into firm, weighty nuggets, indicating a high calyx-to-leaf ratio that simplifies trimming. Dense floral clusters benefit from ample airflow to reduce the risk of botrytis during the final two to three weeks of bloom.
Aroma and Flavor Profile
Consumers commonly describe KC 36’s nose as a blend of sweet citrus, fresh earth, and pine with hints of floral spice. A cut fruit note reminiscent of lemon or orange zest often appears on the initial break of a well-cured bud. Underneath, a mild skunk or hash backbone rounds out the profile, especially in longer cures.
On the palate, the first draw may deliver bright citrus sweetness followed by herbal-earth and a peppery tickle on the exhale. A cooling pine sensation can linger, especially when vaporized at 175 to 190 Celsius, which tends to preserve limonene and pinene. Later sips can reveal a soft, sugary floral tone that pairs well with tea or citrus-forward beverages.
Flavor intensity is notably improved with proper drying and a 4 to 8 week cure at 58 to 62 percent relative humidity. Overly humid storage can dampen the citrus top notes and emphasize earthy components. Keeping jars in a cool, dark environment helps preserve terpene content and delay oxidation of volatiles.
Cannabinoid Composition and Potency
KC 36 is typically reported within a moderate-to-robust THC window, with many grows landing around 16 to 22 percent THC by weight under dialed-in conditions. Outliers above 22 percent can occur with optimized lighting, CO2 supplementation, and precise fertigation. Lower-potency expressions around 12 to 15 percent are possible in low-light or nutrient-stressed environments.
CBD content is generally low, often below 0.5 percent, as is common with legacy hybrid seed lines not bred specifically for CBD. Minor cannabinoids like CBG may appear in trace to low-single-digit percentages pre-decarboxylation and around 0.1 to 0.5 percent in decarbed flower, depending on harvest timing. As a rule, earlier harvests show slightly higher THCA-to-THC ratios, while later harvests increase THC and raise the proportion of oxidized cannabinoids like CBN in stored material.
For context, retail cannabis flower in many legal markets averages roughly 18 to 21 percent THC, based on multi-state testing summaries from 2021 to 2023. Within that frame, KC 36 fits comfortably as a balanced hybrid that can meet or exceed market-average potency with strong cultivation practices. Consumers seeking a moderate yet present psychoactive effect will typically find its potency band accessible but satisfying.
Terpene Profile and Chemistry
KC 36 often presents a terpene spectrum anchored by myrcene with supporting roles from beta-caryophyllene and limonene. In grower and lab reports for similar hybrid profiles, myrcene commonly ranges from 0.4 to 1.2 percent by weight, caryophyllene from 0.2 to 0.6 percent, and limonene from 0.2 to 0.5 percent. Secondary contributors may include alpha-pinene at 0.1 to 0.3 percent and linalool in the 0.05 to 0.2 percent band.
Myrcene is associated with earthy, herbal tones and is frequently cited in consumer anecdotes as a contributor to relaxation and muscle ease. Beta-caryophyllene, a terpene that can act as a selective CB2 receptor agonist, may underlie some reports of reduced inflammation and stress reactivity. Limonene supports citrus aromatics and is studied for mood-elevating and anxiolytic potential in preclinical settings.
The relative proportion of these terpenes can shift with cultivation variables such as light spectrum, substrate composition, temperature, and harvest timing. For example, temperatures above 28 Celsius late in flower can volatilize monoterpenes and decrease detectable content in cured buds. A gentle dry and extended cure at moderate humidity tends to preserve the upper registers of limonene and pinene.
Experiential Effects and Onset
According to Leafly’s strain entry for KC 36, common positive effects include sleepy, euphoric, and uplifted, a pattern consistent with myrcene- and limonene-forward hybrids. Users often report a quick onset within 5 to 10 minutes when smoked and 10 to 20 minutes when vaporized. Peak effects usually persist for 60 to 90 minutes, with a taper over 2 to 3 hours.
Early effects may feature light cerebral euphoria and a lifted mood, followed by a gradual settling into the body. The experience can finish on the sedating side, making KC 36 a popular choice for late afternoon or evening sessions. Many find it suitable for unwinding after work, watching films, or low-intensity creative tasks.
At higher doses, couchlock and drowsiness are more likely, particularly with later-harvested flower exhibiting higher amber trichome ratios. As with most THC-dominant hybrids, dose titration significantly influences the qualitative experience. Individuals sensitive to THC may prefer microdoses or vaporization at lower temperatures to emphasize clarity and reduce intensity.
Potential Medical Applications and Considerations
While cannabis effects vary by person, KC 36’s user-reported profile suggests potential utility for sleep initiation and evening relaxation. The sleepy and euphoric combination is often sought by individuals managing stress-related sleep latency. Myrcene’s sedative associations and beta-caryophyllene’s CB2 activity may complement these effects, though clinical evidence remains limited and context dependent.
Anecdotal reports point to relief for mild to moderate pain and muscle tension, consistent with many THC-dominant hybrids. Preclinical studies support THC’s role in analgesia and caryophyllene’s anti-inflammatory pathways, but dosing must be individualized. Some patients also report appetite stimulation and nausea reduction, effects that THC is known to promote in certain contexts.
People with anxiety sensitivity to THC should approach cautiously, as Leafly users also report occasional paranoia with KC 36. Starting with small inhalation doses or balanced THC-to-CBD combinations can help mitigate adverse reactions. Medical use should be discussed with a licensed clinician, especially when combining cannabis with sedatives, antidepressants, or other medications.
Cultivation Guide: Seeds, Germination, and Early Growth
KC 36 is commonly offered as regular seeds, reflecting KC Brains’ traditional breeding approach; feminized versions may be available from third parties. Germination success rates above 90 percent are achievable using a 24 to 72 hour pre-soak and paper towel method at 22 to 25 Celsius. Plant into a light, aerated starter mix with 20 to 30 percent perlite once radicles reach 0.5 to 1 centimeter.
Seedlings prefer gentle light at 200 to 300 PPFD for the first 5 to 7 days, increasing to 300 to 450 PPFD as true leaves form. Maintain root-zone temperatures near 22 to 24 Celsius and air temperatures at 24 to 26 Celsius with 65 to 75 percent relative humidity. Target pH of 6.3 to 6.5 in soil and 5.7 to 5.9 in hydroponic media.
Feed lightly at 0.4 to 0.6 mS per cm EC with a balanced seedling nutrient, emphasizing calcium and magnesium availability to prevent early deficiency. Water to runoff but avoid oversaturation; a wet-dry cycle promotes root development. Transplant to 3 to 7 liter containers once roots circle the pot and growth accelerates.
Cultivation Guide: Vegetative Phase Management
In veg, KC 36 responds well to topping at the fourth to sixth node, promoting multiple dominant tops. Many growers will mainline or quadline to form an even canopy, particularly effective under LEDs and in tents. Low-stress training can widen branch angles, improving airflow and setting up uniform flower sites.
Provide 18 hours of light and 6 hours dark, with PPFD at 450 to 700 and a daily light integral around 30 to 45 mol per square meter per day. Maintain temperatures at 24 to 28 Celsius with 60 to 70 percent humidity, yielding a VPD between roughly 0.8 and 1.2 kPa. Keep soil pH between 6.3 and 6.8; hydroponic and coco systems fare well at 5.8 to 6.1.
Nutrient strength typically ranges from 1.2 to 1.8 mS per cm EC in veg, increasing as plants size up. A nitrogen-forward profile is appropriate here, but avoid overfeeding as excess nitrogen can reduce internode stacking efficiency. Supplement calcium and magnesium at 100 to 150 ppm combined, particularly in RO or soft water setups.
Cultivation Guide: Flowering Phase and Environmental Controls
KC 36 generally flowers for 7 to 9 weeks indoors, depending on phenotype and environmental optimization. Stretch after flip commonly ranges from 20 to 40 percent, making pre-flip canopy planning important. In northern outdoor climates, harvest is often achievable from late September to early October, allowing avoidance of protracted autumn rains.
During bloom, provide 900 to 1,100 PPFD for mid-to-late flower under CO2 at 800 to 1,200 ppm; without CO2, many growers aim for 750 to 900 PPFD to balance photosynthesis with heat and vapor control. Maintain day temperatures at 22 to 26 Celsius and nights at 18 to 21 Celsius, gradually lowering humidity from 55 percent early bloom to 40 to 45 percent in late bloom. This humidity ramp helps limit botrytis in KC 36’s tight colas.
Defoliate lightly at weeks two to three of bloom to open airflow around inner bud sites, then again, if necessary, at weeks five to six. Avoid aggressive late defoliation that can stress plants and reduce resin output. Support branches with trellis netting, as resin-rich, compact flowers gain significant weight in weeks six to nine.
Cultivation Guide: Nutrition, Irrigation, and Deficiencies
Transition to a bloom nutrient with higher phosphorus and potassium at the start of flower. Many growers target 1.6 to 2.0 mS per cm EC for weeks one to three, 2.0 to 2.3 EC in peak bulk around weeks four to six, and taper to 1.6 to 1.8 EC in the final two weeks before flush. Keep calcium and magnesium at 150 to 200 ppm combined during mid bloom to support cell wall integrity and chlorophyll stability.
KC 36 shows strong response to silica supplementation, which can enhance stem rigidity and abiotic stress tolerance. Irrigate with full saturation and 10 to 20 percent runoff in soilless substrates to prevent salt accumulation. In living soil, water by weight and feel, avoiding overwatering that could depress microbial activity and root oxygenation.
Watch for early magnesium deficiency, which may appear as interveinal chlorosis in older leaves under strong LED lighting. Mild Epsom salt additions at 25 to 50 ppm magnesium or a Cal-Mag blend can correct this within a week. Excess nitrogen late in bloom may delay ripening and mute citrus terpenes, so taper N as pistil recession accelerates.
Cultivation Guide: Training, Canopy, and Space Management
KC 36 performs well in SCROG setups with one to two plants per 60 by 60 centimeter space or four to six plants per square meter. For sea-of-green approaches, run smaller plants in 9 to 12 liter pots with a single topping or even untopped seedlings. The strain’s moderate stretch and sturdy laterals make it adaptable to both methods.
Target an even canopy depth of 20 to 30 centimeters to maximize light penetration and prevent larf. Lollipopping the bottom 20 to 30 percent of the plant reduces popcorn buds and improves airflow. Use oscillating fans to maintain gentle leaf movement throughout the canopy.
When growing multiple phenotypes, group similar vigor and stretch traits together to maintain uniformity under fixed lights. Consider side lighting or reflective walls to improve PPFD in lower canopy regions. Avoid heavy supercropping late in bloom; if necessary, use it early post-flip to tame tall tops without breaking fibers excessively.
Cultivation Guide: Outdoor Growing and Climate Adaptation
KC 36’s Dutch breeding background equips it for northern temperate climates, where summers are mild and humidity can rise in late season. Outdoors, plants thrive in well-amended loam with ample organic matter and drainage. A planting density of one plant per 1.0 to 2.5 square meters provides room for airflow and canopy spread.
In regions between 40 and 50 degrees north latitude, expect finishing from late September to early October. In warmer, drier zones, earlier harvests may be possible, often in mid to late September. Use staking or cages to support maturing colas that can become top-heavy.
For integrated pest management, deploy yellow and blue sticky cards and inspect weekly for mites and thrips. Biological controls such as Phytoseiulus persimilis and Amblyseius cucumeris can keep populations down. To reduce mold risk, prune interior suckers, remove leaves touching soil, and ensure morning sun hits the plants to dry dew quickly.
Harvest, Drying, Curing, and Storage
KC 36 is typically harvested when trichomes are mostly cloudy with 5 to 10 percent amber for a balanced effect. For a more sedative profile aligned with the sleepy user reports, many growers wait for 15 to 25 percent amber. Pistil coloration should also be assessed, with 80 to 95 percent oxidation indicating advanced maturity.
Flush in soil for 7 to 10 days and in hydroponics for 5 to 7 days, monitoring runoff EC to verify nutrient reduction. Aim to dry for 10 to 14 days at 15.5 to 18.5 Celsius and 58 to 62 percent relative humidity with gentle airflow. Stems should snap rather than bend before jarring.
Cure in airtight glass at 58 to 62 percent RH for at least 4 weeks, burping daily for the first 10 to 14 days. Well-cured KC 36 retains its citrus top notes and develops a deeper hash-spice base. Store long term in a dark, cool place; temperatures above 21 Celsius accelerate terpene loss and THC oxidation to CBN.
Yield, Extraction Potential, and Processing
Under optimized indoor conditions, KC 36 can produce approximately 400 to 550 grams per square meter. Outdoor yields vary widely with environment and root volume but commonly range from 500 to 800 grams per plant, with exceptional plants exceeding 1 kilogram in long seasons. Dense bud formation contributes to strong bag appeal and efficient trimming.
The strain’s resin coverage translates to respectable extraction returns. Well-grown, properly cured flower often yields 15 to 20 percent on rosin presses at 82 to 93 Celsius and 650 to 1,000 psi, depending on humidity and bag micron. Hydrocarbon extraction can capture the citrus-forward top notes, while ice water hash favors sticky, intact trichome heads.
For solventless, many processors favor 90 to 120 micron bags for flower rosin and 73 to 120 micron for hash rosin, depending on trichome size. Pre-press pucks improve consistency and reduce blowouts. Keep starting material between 58 and 62 percent RH to optimize pressure transfer and flavor retention.
Risks, Side Effects, and Responsible Use
As noted on Leafly and in user reviews, KC 36’s most common adverse effects include dry mouth and dry eyes, which occur in a substantial portion of THC-dominant strain experiences. Hydration and lubricating eye drops can mitigate these effects. A smaller subset of users reports paranoia or anxiety, especially at higher doses or with rapid consumption.
To reduce intensity, new consumers can start with one to two small inhalations and wait 10 to 15 minutes before redosing. Vaporization at 165 to 180 Celsius can offer a gentler onset and emphasize terpenes tied to uplift and clarity. Individuals with a history of panic or THC sensitivity may prefer lower-THC batches or blending with CBD flower.
Avoid combining KC 36 with alcohol or sedatives, as additive effects can increase impairment and drowsiness. Never drive or operate machinery while under the influence. If adverse reactions occur, stop use and find a calm environment; symptoms often subside within an hour or two as plasma THC levels decline.
Comparisons, Alternatives, and Strain Pairings
Growers who appreciate KC 36 often also consider other KC Brains selections, such as KC 33, for outdoor reliability and early finishing. For consumers seeking a similar citrus-earth profile with a relaxing tilt, hybrids anchored by myrcene and limonene, such as certain phenotypes of White Widow or Critical, may appeal. Those prioritizing sleep may prefer more sedative indica-leaning options while retaining citrus notes, for example phenotypes of OG Kush crosses.
If the goal is daytime clarity without sedation, a limonene-pinene dominant sativa hybrid could be an alternative, albeit with a different effect shape. Conversely, if bodily heaviness is desired with pronounced spice, caryophyllene-forward cultivars like some phenotypes of Bubba-influenced lines might suit. For extraction, cultivars with high resin density and similar flowering times ensure compatible production schedules.
Pairing KC 36 with herbal teas such as chamomile or lemon balm can accentuate its relaxing citrus and floral notes. Citrus zests in mocktails or mild, creamy desserts also complement the palate. Avoid overpowering flavors that could mask the delicate pine and floral edges in vapor.
Buying Tips, Phenotype Selection, and Verification
When sourcing KC 36, prioritize reputable seed banks or distributors known to handle KC Brains Holland genetics. Because exact parentage is not widely publicized, verify lot authenticity by checking breeder packaging and batch codes when available. Request germination guarantees or customer support policies to mitigate the risk of old stock.
During phenotype selection, look for plants that meet your canopy goals and aroma preferences. Shorter, chunky phenotypes may finish on the earlier side and are easier to manage in tight spaces. Taller phenotypes can fill a SCROG more thoroughly and sometimes express brighter citrus terpenes.
For flower purchases, examine trichome coverage, bud density, and terpene freshness. Avoid overly dry buds, as terpene loss accelerates below 55 percent RH. If lab data are available, look for THC in the 16 to 22 percent range and myrcene, caryophyllene, and limonene in the top three terpene slots.
Data Notes and Methodological Caveats
Reported ranges for cannabinoids and terpenes reflect typical outcomes for THC-dominant hybrid cultivars with similar morphology and aromas, combined with grower accounts specific to KC 36. Actual results depend on genetics, environment, nutrition, and post-harvest handling. Where direct lab datasets for KC 36 are limited, conservative ranges and general-market context are provided for orientation rather than definitive specification.
Environmental parameters such as PPFD, EC, pH, temperature, and humidity reflect documented best practices used widely in contemporary cultivation. These ranges are intended as starting points; successful growers will tune them to local conditions and plant feedback. Harvest windows are similarly phenotype dependent and should be validated visually and with a jeweler’s loupe.
User effect profiles and side effects are sourced from public consumer reports, including Leafly’s KC 36 entry noting sleepy, euphoric, and uplifted effects with dry mouth, dry eyes, and occasional paranoia. These experiences vary with dose, tolerance, set and setting, and individual physiology. Consumers should start low, go slow, and consult medical professionals for health-related questions.
