King's Kush emerged from the Dutch breeding scene in the late 2000s, developed by the renowned Green House Seeds, a seed company known for stabilizing high-yielding, high-impact cultivars. The strain quickly gained traction among European growers and coffee shop patrons for its dense resin production and unmistakable grape-kush signature. Within a few seasons, it migrated to North American medical markets, where its indica-forward effects earned it a reputation as a nighttime powerhouse.
The breeder pedigree matters here because Green House Seeds is widely credited with standardizing several modern classics and producing reliable feminized lines. With King's Kush, they set out to capture OG Kush’s punch and structure while layering in a sweeter, fruitier dimension from a Grape parent. The result is a cultivar that reliably expresses dark coloration, compact buds, and a terpene profile that cuts through even congested grow rooms.
A notable development in the lineage’s history is the release of CBD-bearing versions by Green House Seeds, including King’s Kush CBD and an autoflowering CBD counterpart. These variants expanded the strain’s reach beyond recreational circles into wellness-oriented cultivation, thanks to balanced THC:CBD ratios and shorter flowering windows. Over the past decade, both the original and CBD expressions have become staples in seed catalogs and grow diaries worldwide.
Genetic Lineage and Breeding Rationale
King's Kush is a deliberate cross of OG Kush and a Grape cultivar, often reported simply as “Grape” in breeder notes. This pairing targeted a synthesis of OG Kush’s gas, earth, and pine with a dark-fruit overlay and improved color expression from the Grape side. In practice, growers commonly observe strong lateral branching, compact internodes, and high calyx-to-leaf ratios—all desirable attributes for efficient canopy management.
Green House Seeds’ approach with King’s Kush prioritizes resin density and terpene saturation alongside yield. Reports from seed banks and grow communities consistently describe “incredibly high yields” and strong branching, aligning with the breeder’s goals of developing a commercially viable indica-dominant hybrid. The indica dominance also aligns with the functional objective of creating a deeply relaxing chemovar suitable for evening consumption.
The line has spawned offshoots, including King’s Kush CBD (approximately 70% indica / 30% sativa) that balances THC and CBD at roughly 1:1, and an autoflowering CBD variant for faster, more compact grows. These derivatives preserve the flavor identity while adjusting cannabinoid ratios for different user needs. Together, the family demonstrates how a single core cross can be adapted for both potency-driven and wellness-focused outcomes.
Appearance and Structure
Mature King’s Kush plants display a squat-to-medium architecture with vigorous lateral branching, a trait that lends itself to ScrOG nets and even light distribution. Internode spacing tends to be tight, forming dense stacks that finish into heavy, golf-ball-to-cola-sized buds. Under cooler nighttime temperatures, anthocyanins often push through, revealing deep purples against dark green foliage.
Buds are compact, with high calyx density and a thick trichome crust that gives a frosted appearance in late flower. Many phenotypes exhibit prominent burnt-orange pistils that contrast vividly with the darker leaf matter. The resin production is substantial enough that scissors gum up quickly, a telltale sign of the strain’s high trichome gland density.
Leaf morphology skews indica: broader leaflets, sturdy petioles, and a leaf-to-bud ratio that makes final manicuring efficient. Stems are stout yet flexible, accommodating topping and low-stress training without excessive risk of snapping. In well-tuned environments, plants maintain a balanced canopy that is easy to manage during both veg and bloom.
Aroma and Bouquet
The nose on King’s Kush is unmistakable: a blend of sweet grape, overripe berries, and classic Kush earth backed by diesel and pine. Freshly rubbed sugar leaves release a peppery pop, hinting at a caryophyllene-forward terpene profile. Breaking apart cured flowers intensifies the fruit notes while unlocking incense, sandalwood, and faint herbal tones.
In controlled post-cure assessments, many growers note that grape and berry dominate at first sniff, while earthy-gassy components build in the background. As the jar breathes, limonene and pinene brighten the top, widening the aromatic bandwidth and keeping the profile from feeling too heavy. The overall bouquet is loud enough that a single jar can perfume a small room within minutes.
Terpene intensity correlates strongly with cultivation choices, especially late-flower temperatures and drying parameters. When dried around 60°F/60% RH for 10–14 days, the fruit and incense layers persist with minimal terpene volatilization. Overly warm dries tend to mute the grape and accentuate the wood and fuel, changing the balance of the profile.
Flavor Profile
On the palate, King’s Kush delivers a deep, jammy grape layered over earthy Kush, with a peppery finish that tingles on the exhale. Vaporization at 180–190°C brings out candied berry and citrus-zest nuances, while higher temperatures emphasize pine resin and diesel. The mouthfeel is dense and slightly syrupy, a trait common to purple-leaning indica hybrids.
Many users report that the first two pulls are the sweetest, after which the gassy backbone takes center stage. A clean white ash and smooth draw are typical when plants are flushed adequately and dried slowly. Notably, glassware accentuates the grape-candy impression, whereas joints and blunts tend to emphasize the woody-spicy finish.
The flavor remains persistent across the session and can linger on the palate for several minutes. Pairings that complement the profile include dark chocolate, black tea, and aged cheeses, which highlight both the fruitiness and the savory Kush elements. Concentrates made from King’s Kush often showcase an even punchier grape-incense top note due to terpene concentration.
Cannabinoid Profile and Potency
Across tested batches in legal markets, King’s Kush typically lands in the high-THC category, with most samples reporting 18–24% THC by weight. Well-optimized grows have been known to test above 25% THC, though these are outliers tied to exceptional environmental control and post-harvest handling. CBD content in the standard photoperiod cultivar is usually minimal, commonly below 0.5%.
Minor cannabinoids often detected include CBG in the 0.2–1.0% range and trace THCV, though these numbers vary widely by phenotype and cultivation method. Total cannabinoid content in artisan batches regularly surpasses 20–26%, especially when total terpene content is maintained in the 1.5–3.0% range. This synergy contributes to a robust entourage effect that users describe as “heavy yet clear-headed” during the first phase of the experience.
By contrast, King’s Kush CBD from Green House Seeds is bred for a near 1:1 THC:CBD ratio and is listed at approximately 70% indica / 30% sativa. Typical outcomes for the CBD variant are balanced cannabinoid totals such as 8–10% THC paired with 8–10% CBD after about 9 weeks of flowering. This balanced profile markedly changes the effect curve—less intoxication, more body comfort, and greater suitability for daytime symptom management.
Terpene Profile and Chemistry
King’s Kush commonly expresses a terpene stack headlined by beta-caryophyllene, myrcene, and limonene, with supporting roles from humulene, linalool, and pinene. In well-grown indoor batches, total terpene content often falls between 1.5–3.0% by weight, which is above the market average for many indica-dominant cultivars. Myrcene frequently ranges from 0.5–1.2%, contributing to the musky, ripe-fruit foundation and relaxing body tone.
Beta-caryophyllene, typically 0.4–0.8%, adds peppery spice and interacts with CB2 receptors, which may partially underlie the strain’s perceived analgesic qualities. Limonene, often 0.2–0.6%, lifts the top notes with citrus while modulating mood and perceived stress. Secondary terpenes like humulene (0.1–0.3%) and linalool (0.05–0.2%) add woody, floral intricacies and may enhance the calming aspect of the effect.
Terpene expression is sensitive to late-stage cultivation conditions. Cooler nights in late flower and gentle handling during trimming help preserve monoterpenes that are otherwise prone to volatilization. A slow cure with steady humidity (58–62% RH in sealed containers) maximizes terpene retention and stabilizes the grape-incense signature over time.
Experiential Effects and Onset
Most users describe King’s Kush as a deep, body-forward relaxant with a strong euphoria that arrives within 5–10 minutes when inhaled. The onset can feel deceptively gentle for the first few minutes and then “settle in” as muscle tension melts away and sensory depth increases. Peak effects typically occur 30–60 minutes after ingestion and can persist for 2–4 hours depending on dose and tolerance.
Psychoactive qualities include mood elevation, quiet focus, and a warm, weighted calm that edges into couch-lock at higher doses. The strain is considered evening-leaning; it commonly encourages rest, appetite, and a slower pace. First-time users should start conservatively, as the transition from comfortable relaxation to heavy sedation can be abrupt with THC-rich phenotypes.
Common side effects are dry mouth, dry eyes, and occasional dizziness in sensitive individuals, particularly when standing quickly. Hydration, light snacks, and a comfortable setting mitigate most adverse reactions. For those seeking a gentler ride, King’s Kush CBD offers a similar flavor experience with a clearer head and softer physical intensity.
Potential Medical Applications
User reports and clinician anecdotes suggest King’s Kush may help with pain, insomnia, and stress-related tension due to its indica-forward body relief. The caryophyllene-myrcene-limonene stack aligns with many relaxation and sleep-oriented outcomes, with myrcene often associated with reduced motor agitation. In informal patient surveys common in medical markets, high-THC indica-dominant strains frequently see 60–75% of respondents citing improved sleep quality and reduced sleep latency.
Chronic pain and muscle spasm are other domains where King’s Kush is often selected. Patients describe relief that builds steadily during the first hour and remains stable for 2–3 hours, reducing the need for frequent redosing. Appetite stimulation is also notable, with many users reporting increased interest in food within 30–90 minutes of consumption.
For daytime function or sensitivity to THC, the 1:1 King’s Kush CBD variant presents a compelling alternative. Balanced THC and CBD often translate to lower anxiety potential and a clearer cognitive profile while maintaining physical comfort. As always, medical use should be discussed with a qualified clinician, and dosing should follow a start-low, go-slow approach.
Comprehensive Cultivation Guide
Growth habit and difficulty: King’s Kush is an indica-dominant photoperiod cultivar that grows vigorously with strong lateral branching and compact internodes. Difficulty is moderate; it responds well to training and rewards attentive environment control with high-yield, high-terpene flowers. Its stout frame and dense buds necessitate good airflow and humidity management to prevent botrytis in late flower.
Environment: Aim for day temperatures of 22–26°C and nights of 18–21°C during flower, with a slight 3–5°C drop at lights off to encourage color. Keep relative humidity around 55–65% in veg, 40–50% in flower, and 35–40% in the final two weeks. Vapor pressure deficit targets of 0.9–1.2 kPa in veg and 1.2–1.5 kPa in flower promote steady transpiration and nutrient uptake.
Light and intensity: In veg, 300–500 µmol/m²/s PPFD (18/6) produces tight internodes without excessive stretch. Flowering thrives at 700–900 µmol/m²/s PPFD (12/12), with advanced growers pushing 900–1000 under supplemental CO2. Keep light distance and intensity balanced to avoid foxtailing while maintaining high resin output.
Medium and nutrition: King’s Kush performs well in soil, coco, and hydro, with coco offering rapid growth and precise steering. Target pH of 6.2–6.8 in soil and 5.8–6.2 in hydro/coco. Electrical conductivity guidelines: 1.2–1.6 mS/cm in veg, rising to 1.6–2.0 mS/cm in mid-late flower, tapering during the final 7–10 day flush.
Feeding and supplements: OG-derived lines often exhibit higher calcium and magnesium demand; a Cal-Mag supplement at 100–150 ppm Ca and 40–60 ppm Mg is useful, especially under LED lighting. Introduce a modest P–K boost around weeks 4–7 of bloom to support bulking without overshooting nitrogen. Silica at 30–50 ppm strengthens stems, aiding heavy colas.
Training: The strain’s branching makes it ideal for topping, LST (low-stress training), and ScrOG. Topping once or twice in veg (third to fifth node) can create 8–16 productive tops per plant, depending on veg time. Defoliate lightly to improve airflow and light penetration—remove large fans that shade inner sites around weeks 3 and 6 of flower.
Irrigation strategy: In coco or rockwool, frequent small irrigations that return to 20–30% runoff help maintain stable EC and root zone oxygen. In soil, water to full saturation and then allow 30–50% pot dryback before the next irrigation to minimize overwatering risk. Root-zone temperatures around 20–22°C support robust microbial and root activity.
Pest and disease management: Dense buds demand proactive IPM. Introduce beneficials such as A. swirskii and N. californicus during veg to manage mites and thrips. Maintain strong airflow (0.5–1.5 m/s across the canopy), prune lower larf, and keep RH under 50% in late flower to reduce botrytis and powdery mildew pressure.
Flowering time and photoperiod: The standard King’s Kush typically finishes in 8–9 weeks of bloom, with 9 weeks being a common sweet spot for maximum resin and terpene development. Phenotypes with heavier Grape expression sometimes benefit from an extra 3–5 days to deepen color and flavor. Flip to flower when plants have filled 70–80% of the intended canopy footprint to control final height.
Plant density and container size: In a ScrOG, expect 4–6 plants per square meter in 11–15L containers with a 4–6 week veg. For SOG, 9–16 smaller plants per square meter in 5–7L containers can speed turnover, though individual plant training is reduced. Sturdy trellising or yo-yos are recommended; mature colas can sag under their own weight.
Outdoor cultivation: In warm, dry climates with cool nights, King’s Kush can surge in yield and color. Expect harvest around late September to early October at mid-latitudes. Provide good sun exposure, consistent feeding, and preventive pest control; outdoor yields of 900–1200 g per well-grown plant are achievable in ideal conditions.
Autoflower and CBD variants: Green House Seeds also offers King’s Kush CBD (70% indica / 30% sativa, approximately 1:1 THC:CBD, ~9 weeks flower) and an Autoflowering CBD expression for faster crops. The autos finish in 9–10 weeks from sprout depending on environment and light cycle, making them suitable for balconies or short seasons. Expect slightly lower yields per plant with autos but multiple annual cycles in favorable climates.
Post-harvest handling: To preserve the grape-incense terpene stack, dry at approximately 60°F/60% RH for 10–14 days with gentle airflow and darkness. After stem-snap, cure in airtight containers at 58–62% RH, burping daily for the first week and weekly thereafter. A 4–8 week cure meaningfully enhances smoothness and flavor persistence.
Harvest, Drying, and Curing
Timing harvest by trichome maturity is crucial for tailoring effects. For a balanced relaxing yet functional profile, target mostly cloudy trichomes with 5–10% amber. For heavier sedation and body impact, let amber rise to 10–20%, typically extending harvest by 3–5 days.
When cutting, handle flowers by the stem and avoid overhandling to protect trichome heads. Whole-plant hangs slow the dry and can lock in more terpene content, especially in arid climates. If humidity is high, consider branch-level hangs with increased spacing to prevent microclimates.
Maintain 60°F (15.5–16.5°C) and 58–62% RH during dry with gentle, indirect airflow; direct fans should never hit the flowers. The ideal drying window is 10–14 days, resulting in a clean break at smaller stems and a leathery feel to outer calyxes. After jarring, monitor internal RH with hygrometers and stabilize at 58–62% for a slow, controlled cure.
Curing for 4 weeks unlocks the full grape-kush bouquet, while 8 weeks or more can round off any remaining astringency. Keep containers in a cool, dark place to protect volatile monoterpenes and THC from degradation. Aim for water activity between 0.55–0.65 to balance safety and flavor longevity.
Yields, Performance Metrics, and Phenotype Notes
King’s Kush is frequently cited for “incredibly high yields,” a claim that aligns with the strain’s heavy bud set and solid density. Indoors, optimized ScrOG runs regularly report 600–800 g/m² under high-efficiency LEDs at 700–900 µmol/m²/s. CO2 enrichment (800–1200 ppm) and dialed irrigation can push yields higher, provided environmental constraints are respected.
Outdoors, mature plants in 50–100L containers or in-ground beds can reach 900–1200 g per plant in warm, sunny climates with low late-season humidity. In cooler regions, a greenhouse with dehumidification can preserve yields by reducing botrytis risk. The cultivar’s natural branching reduces the need for aggressive topping, but strategic training improves uniformity and depth of canopy illumination.
Phenotype spread includes two dominant expressions: a grape-forward, dark-hued phenotype with marginally shorter stature, and a slightly taller, more OG-leaning type with stronger fuel-pine and brighter lime-green buds. Both finish in roughly 8–9 weeks, with the grape-leaner generally showing more purple under cool nights. Growers seeking maximal color should drop night temps by 3–5°C in late weeks while maintaining RH controls.
In concentrate production, King’s Kush performs well in both hydrocarbon and rosin formats. Hash yields are competitive due to high trichome density, with skilled processors regularly reporting strong returns and a terp-forward finished product. The grape-incense top notes are particularly pronounced in live extracts where monoterpenes are preserved.
Context and Verified Lineage Notes
Green House Seeds is credited as the original breeder of King’s Kush, and widely circulated seed listings corroborate the OG Kush x Grape parentage. Multiple retail and seed catalog sources describe the strain as mostly indica, consistent with its growth habit and effects. Public-facing product descriptions emphasize its strong branching and high-yield potential, aligning with grower reports.
A notable expansion of the line includes King’s Kush CBD, frequently described as a 70% indica / 30% sativa hybrid with a near 1:1 THC:CBD ratio, finishing in about 9 weeks of flower. An autoflowering CBD variant is also distributed, widening the cultivation use cases for short-season or discrete growers. Together, these data points place King’s Kush among Green House Seeds’ versatile, production-friendly offerings.
While specific cup wins may vary by locale and year, the strain’s persistence in seed catalogs and grow diaries speaks to its reliability and commercial viability.

For lineage purists, the OG and Grape inputs are evident in both morphology and sensory output.
Practical Usage and Dosing Considerations
For inhalation, newcomers might begin with 1–2 small puffs and wait 10–15 minutes before redosing, given King’s Kush’s delayed heavy finish. Experienced consumers commonly find 2–4 puffs sufficient for evening relaxation, with larger doses reserved for late-night sedation. Vaporization allows finer control and highlights the sweeter top notes at lower temperatures.
For edibles or tinctures made with King’s Kush, start with 1–2 mg THC and titrate slowly to avoid overshooting, especially with non-CBD-dominant preparations. The CBD version of King’s Kush enables higher functional doses thanks to its balanced cannabinoid ratio, which many users find steadier during daytime. Regardless of route, maintaining hydration and a calm setting improves overall experience and reduces unwanted effects.
Tolerance, body weight, and individual endocannabinoid variability significantly influence outcomes. Users on sedating medications should consult healthcare providers before combining with high-THC cannabis. When in doubt, start low, go slow, and keep a simple log to track what dose windows produce consistent results.
Legal and Safety Considerations
Cultivating or possessing King’s Kush is subject to local laws that vary by country, state, and municipality. Growers should verify statutes on plant counts, THC thresholds, and home cultivation permissions before starting. Seed acquisition should be conducted through reputable, legal channels to ensure genetic authenticity and compliance.
Safety-wise, ensure proper ventilation when growing indoors to manage humidity, heat, and CO2 if used. Electrical loads from lighting and HVAC systems must be calculated carefully and installed with appropriate breakers and wiring. For extraction, only trained professionals using compliant equipment should attempt hydrocarbon methods; home solventless (ice water hash or rosin) is safer.
Consumption should be avoided by individuals who need to operate heavy machinery or drive, and by those with contraindicated medical conditions unless cleared by a clinician. Keep products out of reach of children and pets, and store securely in labeled containers. As with all cannabis use, moderation and informed decision-making are key.
