Kush of Ra is a mostly indica cannabis cultivar developed by the breeder Kuntry Greenthumb, a name that signals both a Kush-forward direction and a craftsman approach. The strain name nods to Ra, the Egyptian sun deity, suggesting a sun-warmed, resin-heavy Kush with classic Afghan lineage sensibilities. In practice, most growers and consumers describe it as a compact, dense-budded indica-leaning phenotype with a heavy, soothing finish.
Because public, lab-verified documentation on Kush of Ra is limited, much of what is known comes from grower reports and the broader performance envelope of modern Kush varieties. Indica-dominant Kush lines routinely deliver robust resin, tight node spacing, and a terpene profile led by earthy, gassy, and citrus-peel notes. Kush of Ra appears to align with this profile while adding a layered, incense-like complexity.
From an effects standpoint, Kush of Ra is generally positioned as evening-friendly and body-forward, supporting relaxation, appetite, and sleep hygiene. While daytime microdosing can be workable for some, potency and sedative terpenes often steer consumers to twilight use. With appropriate dose control and a slow-start approach, it can also be a reliable wind-down option for high-tolerance users.
As a cultivation subject, Kush of Ra behaves like a true indica-dominant Kush, preferring moderate canopy temperatures, high light intensity, and low-to-moderate relative humidity during bloom. Its dense flowers demand good airflow and proactive pathogen management, especially in the last three weeks. For growers who dial in environment and nutrition, the strain rewards with frosty, aromatic colas and consistent yields.
Origins and History
Kush of Ra traces its origins to Kuntry Greenthumb, who selected and stabilized a mostly indica expression consistent with Kush heritage. The breeder identity provides a key anchor for those seeking lineage continuity with resin-heavy, stout cultivars. While the exact parental cross has not been publicly disclosed as of this writing, the strain’s behavior aligns closely with classic Afghan-OG pedigrees.
In the contemporary market, many Kush introductions emerge through limited seed drops, clone-only releases, or small-batch phenohunts. Kush of Ra appears to have followed a similar artisanal path, gaining recognition in grower circles before entering broader circulation. Such pathways typically result in a high phenotype-to-phytochemical consistency once a keeper cut is identified and propagated.
From a cultural standpoint, the Ra reference is telling; it evokes warmth, gold-toned resin, and a desert-born lineage. Kush lines historically descend from Hindu Kush and related Central/South Asian landraces selected for hash production. Kush of Ra honors that tradition through dense glandular trichomes and a terpene ensemble that leans earthy, spicy, and citrus-resinous.
The strain’s reputation has been shaped by practical performance: reliable flowering times, low-stretch structure, and a terpene density that survives the cure. In markets where consumer preference favors gassy, citrus, and incense-like kush notes, Kush of Ra fits an increasingly popular niche. Collectively, these traits keep it on the radar of both home cultivators and boutique producers.
Genetic Lineage and Breeding Context
Kuntry Greenthumb bred Kush of Ra as a mostly indica cultivar, and the phenotype traits strongly suggest a backbone rooted in Afghan and OG-style Kush genetics. These lineages are known for stout frames, broad leaflets, and an ability to stack calyxes into hard, resin-capped clusters. Although the parental cross is not publicly confirmed, the observed chemotype aligns with the Kush family archetype.
Most indica-dominant Kush cultivars exhibit short internodes, a low side-branch-to-apex ratio without training, and a high calyx-to-leaf ratio by late flower. Kush of Ra tends to display these characteristics, especially under high light intensity and moderate nitrogen input. The combination creates a canopy that can be sculpted easily for SCROG or SOG layouts.
Chemically, Kush families commonly feature THC-dominant chemovars with total terpene concentrations between 1.5% and 3.0% by dry weight in optimized indoor conditions. Terpene drivers often include beta-caryophyllene, limonene, myrcene, and humulene, which together contribute to the earthy gas, citrus rind, and spicy incense notes that many report in Kush of Ra. The interplay of these compounds tends to correlate with sedative, anxiolytic, and appetite-stimulating effects.
Given the breeder’s emphasis and the strain’s performance envelope, growers should anticipate an 8 to 9 week flowering period in most indoor environments. In outdoor settings with a temperate or Mediterranean climate, finishing typically lands from late September to early October. This timeline reflects the practical reality of indica-forward Kush cultivars selected for reliable early finishing.
Visual Appearance and Structure
Kush of Ra typically forms compact plants with broad, deep-green fan leaves and short internodes. In vegetative growth, the structure is symmetrical, with an apical dominance that benefits from topping to flatten the canopy. Trained plants display a well-distributed array of spear-shaped colas that harden rapidly in mid-to-late flower.
Buds are dense and resinous, exhibiting a calyx-to-leaf ratio often around 2:1 to 3:1 by harvest. Pistils mature from a vibrant orange into copper and rust hues as trichomes develop from clear to cloudy. Under cooler nights below about 68°F, some phenotypes can express anthocyanin pigmentation, adding purple accents to sugar leaves and bracts.
Trichome coverage is typically abundant, with bulbous heads that press easily into sticky resin when gently touched. Growers report a high proportion of capitate-stalked trichomes, a hallmark of well-bred Kush lines optimized for both flower and hash production. Proper environmental control during late flower helps maximize head integrity and terpene retention.
Average plant height indoors ranges from 24 to 40 inches without aggressive training, making it manageable in tents and low-ceiling rooms. Outdoors, plants can exceed 5 feet with adequate root volume and full sun exposure. Across scenarios, consistent airflow is vital to prevent condensation within the dense inflorescences.
Aroma and Bouquet
The aroma profile of Kush of Ra leans classic Kush with a modern twist: earthy base notes, gassy overtones, and a citrus-incense lift. Beta-caryophyllene and humulene drive the spicy, woody foundation, while limonene and pinene brighten the nose with lemon peel and fresh-cut conifer. Myrcene threads everything together with a slightly musky, herbal undertone.
On a fresh grind, volatile terpenes are released rapidly, and the aromatic intensity noticeably spikes relative to whole flower. Sensory panels routinely report that grinding increases perceived aroma strength by 30% to 40% compared to intact nugs, a normal reflection of surface area and volatility. That pop often reveals a sharper diesel component alongside a rounded, sweet resin character.
During the cure, the bouquet evolves from sharp citrus-gas to a more integrated incense-resin harmony. After 3 to 6 weeks in a proper 58% to 62% relative humidity cure, many find the sharp edges smooth into a creamy kush aroma. At 8 weeks and beyond, deeper sandalwood and hashish notes can emerge as monoterpenes equilibrate and sesquiterpenes become more pronounced.
Storage conditions significantly influence nose preservation. When dried at about 60°F and 60% RH for 10 to 14 days, followed by a cool, dark cure, terpene retention tends to be 15% to 30% higher than quick-dried flower stored warm. This is consistent with data showing monoterpenes like limonene and myrcene volatilize rapidly above 70°F and in low humidity environments.
Flavor and Mouthfeel
Kush of Ra carries forward its bouquet into a layered flavor experience. Initial puffs often present lemon zest, earthy hash, and a mild diesel bite that tickles the palate. As the session progresses, black pepper and pine resin linger on the exhale.
The mouthfeel is creamy for a Kush, especially after a slow cure that preserves monoterpenes and softens chlorophyll notes. Balanced mineral nutrition and a clean flush in the last 7 to 10 days help avoid bitterness and harshness. Many users describe the aftertaste as a warm resin sweetness with hints of sandalwood and citrus pith.
Combustion versus vaporization can shift the flavor emphasis. Vaporizers set around 370°F tend to showcase limonene and pinene, emphasizing citrus and pine. At higher temperatures of 390°F to 410°F, spicy and woody sesquiterpenes like beta-caryophyllene and humulene become more prominent.
For hash and rosin, the flavor concentrates around the same drivers, often intensifying the incense-gas character. Mechanical separation and ice-water extraction preserve more high-note terpenes when performed cold. A well-cured sample translates particularly well into solventless rosin with a rounded, dessert-kush finish.
Cannabinoid Profile and Potency
As a mostly indica Kush, Kush of Ra is expected to express a THC-dominant chemotype. Across U.S. markets, indica-forward Kush cultivars commonly test in the 18% to 26% THC range, with select phenotypes surpassing 28% under optimal cultivation and careful post-harvest handling. While official, published certificates of analysis for Kush of Ra are limited, grower benchmarks place it solidly within this potency envelope.
CBD expression is generally low in THC-dominant Kush lines, commonly below 0.5% and often below 0.2%. Minor cannabinoids can be present in trace to moderate levels, with CBG frequently appearing in the 0.2% to 1.0% range, and CBC and THCV usually below 0.3%. These minor constituents may modulate the subjective profile but rarely dominate the effect.
Potency perception is not solely a factor of THC percentage; terpene content and ratio play a significant role in onset and intensity. Flower samples with total terpene content above 2.0% by weight often feel more robust at equivalent THC levels. This is due to terpene-driven pharmacokinetic effects and sensory synergy that can alter how quickly and strongly effects are experienced.
Inhaled onset typically occurs within 2 to 5 minutes, with peak effects around 30 to 60 minutes and a total duration of 2 to 4 hours for most users. Oral forms can extend duration to 6 to 8 hours or more due to 11-hydroxy-THC formation in first-pass metabolism. Dose titration remains the critical strategy to avoid overshooting comfort, especially in new or sensitive consumers.
Terpene Profile and Aromatic Drivers
Kush of Ra features a classic Kush terpene framework dominated by beta-caryophyllene, limonene, myrcene, and humulene, with secondary contributions from linalool and pinene. In optimized indoor runs, total terpene content for Kush-type cultivars commonly sits between 1.5% and 3.0% by dry weight. Within that total, beta-caryophyllene and limonene frequently combine for 0.4% to 1.4%.
A realistic estimated breakdown for well-grown Kush of Ra phenotypes is as follows: myrcene at 0.4% to 1.0%, beta-caryophyllene at 0.2% to 0.8%, limonene at 0.2% to 0.6%, humulene at 0.1% to 0.3%, linalool at 0.05% to 0.2%, and pinene at 0.05% to 0.15%. Actual values vary with phenotype and cultivation parameters such as light intensity, nutrient balance, and drying conditions. These ranges reflect typical outputs from indica-leaning Kush families rather than a single fixed chemotype.
Each terpene contributes distinct sensory and functional attributes. Beta-caryophyllene, a CB2 receptor agonist, adds spicy, woody depth and may modulate inflammation pathways. Limonene supplies bright citrus and has been associated with mood-elevating effects in preliminary research.
Myrcene imparts herbal musk and is frequently discussed for its sedative, body-forward synergy when paired with THC. Humulene reinforces woody-bitter top notes and may contribute mild appetite modulation. Linalool adds a floral, lavender-like edge that some users experience as calming, especially in evening sessions.
Experiential Effects and Onset
Most users describe Kush of Ra as calming, body-centric, and thoroughly relaxing, with a gentle mental wind-down that intensifies across the first hour. The effects are front-loaded in the body, giving a heavy-lidded comfort that pairs well with music, films, or quiet conversation. Mental clarity can remain workable in low doses, but higher doses tend to invite couchlock.
On inhalation, onset is noticeably quick, typically within 2 to 5 minutes, with the first wave cresting at 15 to 30 minutes. A second, deeper plateau often arrives by the 45-minute mark as slower-absorbing cannabinoids and terpenes equilibrate. Many report peak relaxation between 45 and 90 minutes, tapering into a lingering afterglow.
Common acute effects include dry mouth and dry eyes, which are reported in roughly 30% to 50% of cannabis sessions across user surveys. Heart rate can transiently increase, and coordination may be impaired, particularly at higher doses. Anxiety incidence is generally lower with indica-forward Kushes than with racy sativas, but sensitive users should still start low and go slow.
When vaporized at moderate temperatures, the mental haze is often lighter, preserving more of the citrus-pine brightness that can feel more functional. Combustion in larger amounts tends to drive a heavier, more sedative arc. For new users, keeping single-session THC intake to 5 to 10 mg inhaled equivalent is a conservative starting point, adjusting upward carefully.
Potential Medical Applications
Kush of Ra’s mostly indica backbone and terpene ensemble position it well for evening symptom management. Users commonly reach for Kush profiles to address stress, pain, insomnia, and appetite stimulation. While robust clinical trials on this exact strain are lacking, observational studies of THC-dominant flower show substantial self-reported relief across these domains.
For pain, inhaled cannabis has yielded clinically meaningful reductions in patient-reported pain scores, often in the range of 2 to 4 points on 0 to 10 scales within 20 to 30 minutes. Beta-caryophyllene’s CB2 agonism is mechanistically supportive of anti-inflammatory effects, complementing THC-mediated nociceptive modulation. Myrcene may further enhance analgesic synergy, particularly in body-centric presentations.
For sleep, indica-forward chemotypes rich in myrcene and linalool are frequently associated with improved sleep latency and subjective sleep quality. Evening dosing 60 to 90 minutes before bed aligns peak sedative effects with typical bedtime. Keeping total THC dose moderate helps avoid biphasic disturbances or next-day grogginess.
Anxiety responses are highly individualized, but limonene and linalool have shown anxiolytic potential in preclinical and limited human studies. Combining these with a calm setting, measured dose, and slow inhalation cadence can reduce the likelihood of acute anxiousness. For appetite support, THC remains one of the most reliable agents, and Kush of Ra appears to perform as expected for indica Kush lines.
Patients should consider potential side effects and medication interactions. Dry mouth, orthostatic lightheadedness, and psychomotor impairment are common dose-related issues. Medical decisions should always be made in consultation with a qualified healthcare professional, especially for individuals with cardiovascular risk or psychiatric sensitivities.
Comprehensive Cultivation Guide for Kush of Ra
Kush of Ra grows like a classic indica-leaning Kush: compact, resinous, and responsive to training. Indoors, it thrives under high-efficiency LEDs, steady VPD control, and a disciplined nutrient program. Outdoors, it prefers warm, dry late seasons with abundant sun and good airflow.
Germination typically completes within 24 to 72 hours at 72°F to 80°F with a relative humidity of 80% to 95%. Use sterile media, very light moisture, and avoid overhandling the taproot. Early seedling success is improved with gentle light at 150 to 250 PPFD and minimal fertilization, around 0.3 to 0.6 EC.
Vegetative growth is robust under 18 hours of light, with canopy temperatures of 75°F to 82°F and RH at 60% to 70% early, tapering to 55% to 60% by late veg. Aim for a VPD of 0.8 to 1.2 kPa to promote leaf gas exchange without excessive transpiration. Light intensity of 300 to 500 PPFD is sufficient for compact growth and root development.
In veg, top at the fifth node and consider low-stress training to open the center of the plant. Kush of Ra responds well to SCROG; a 2 by 2 inch net can even out apical vigor and increase lateral bud sites. Lollipopping 10% to 20% of the lower canopy before flip helps focus resources into the top colas.
For nutrition, a 3-1-2 N-P-K balance in veg with 150 to 200 ppm calcium and 50 to 70 ppm magnesium supports sturdy growth. Silica at 50 to 100 ppm can improve cell wall strength and pest tolerance. Maintain substrate pH at 6.2 to 6.8 in soil and 5.7 to 6.2 in coco or hydroponics.
Flowering runs 8 to 9 weeks for most phenotypes, with some finishing in 56 to 63 days and others pushing to 63 to 70. Expect minimal stretch for a Kush, roughly 30% to 75%, depending on the veg maturity at flip and light intensity. Canopy temperatures of 74°F to 80°F and RH of 45% to 55% early flower, tapering to 40% to 45% in the last two weeks, reduce pathogen risk.
Increase PPFD to 700 to 900 by week two of flower, and consider supplemental CO2 at 800 to 1,200 ppm to improve photosynthesis and yield. In many rooms, CO2 enrichment of this magnitude can boost dry yield by 15% to 25% when combined with adequate light and nutrition. Ensure daily light integral remains consistent by maintaining fixture distance and verifying with a PAR meter.
Nutrient ratios shift in bloom: early flower benefits from approximately 1-2-2 N-P-K, transitioning to 0-3-3 as senescence approaches. EC commonly rises to 1.6 to 2.2 depending on cultivar appetite and media buffering. Watch for potassium excess, which can induce calcium and magnesium uptake issues and manifest as interveinal chlorosis or brittle leaves.
Kush of Ra forms dense colas, so airflow is non-negotiable. Maintain canopy airspeed around 0.3 to 0.5 meters per second and ensure at least one oscillating fan per 4 to 6 square feet of canopy. Dehumidification must keep vapor pressure deficit within 1.2 to 1.5 kPa during mid-to-late flower to prevent condensation inside buds.
Pest and disease management should be proactive. Predatory mites such as Amblyseius swirskii or A. cucumeris help manage thrips, while Phytoseiulus persimilis targets spider mites. For disease, a rotation of biologicals like Bacillus subtilis and Bacillus amyloliquefaciens in veg can suppress powdery mildew, with sulfur allowed only pre-flower to avoid terpene carryover.
Kush of Ra’s modest internode spacing makes strategic defoliation helpful. Remove large fan leaves that shade bud sites at weeks 3 and 6 of flower, taking care not to stress the plant excessively. Keep total leaf removal under 25% in any single session to preserve photosynthetic capacity.
When grown in coco or hydro, aim for a wet-dry cycle that achieves 10% to 15% runoff per feed, ensuring salts do not accumulate. In soil, water when the top inch dries and the pot feels light, avoiding chronic saturation. Pot sizes of 3 to 5 gallons indoors allow a good balance of root mass and manageable irrigation schedules.
Outdoor cultivation favors warm days, cool nights, and low late-season humidity. In Mediterranean climates, plan for harvest from late September to early October at mid-latitudes. Provide 20 to 50 gallon containers or raised beds, and be prepared to deploy trellis and windbreaks to protect heavy colas.
Clonal propagation is straightforward. Take 4 to 6 inch cuts with two nodes, dip in a 0.2% to 0.6% IBA rooting gel, and place into a pre-moistened medium at 0.4 to 0.6 EC and 5.8 to 6.0 pH. Maintain 80% to 95% humidity for the first 72 hours and 200 to 300 PPFD; roots generally show in 10 to 14 days, with transplant readiness in 14 to 21.
Phenotype selection should weigh internode spacing, resin head size, terpene density, and bud density against mold resistance. Stress testing under mild drought and moderate light intensity helps reveal weak performers before production. Keep detailed logs on feed, environment, and aroma intensity to support data-driven keeper selection.
Harvest timing is best determined by trichome color rather than a calendar date. For a balanced effect, target approximately 5% to 10% amber with 60% to 70% cloudy heads under a jeweler’s loupe or microscope. A pre-harvest flush of 7 to 10 days in coco or hydro, or a gentle taper in living soil, helps improve burn quality and flavor.
Drying should occur at roughly 60°F and 60% RH for 10 to 14 days with low, indirect airflow and complete darkness. Rapid drying above 70°F or below 50% RH increases terpene loss and chlorophyll harshness. A slow dry typically preserves 15% to 30% more monoterpenes than a fast dry, which is noticeable on the nose and palate.
Curing in airtight glass at 58% to 62% RH for 2 to 8 weeks rounds the profile into a richer incense-gas character. Burp jars daily for the first week, then every 2 to 3 days as moisture equilibrates. Fully matured flower remains stable longest when stored cool, dark, and dry, with the container opened sparingly.
Yield expectations depend on environment and skill. Indoors, trained plants under 700 to 900 PPFD with optimized CO2 often produce 450 to 600 grams per square meter; highly dialed runs can exceed 2.0 grams per watt in efficient LED rooms. Outdoors, single plants in large containers or beds commonly return 600 grams to over 1 kilogram of dry flower, assuming a dry fall and full sun.
For concentrates, Kush of Ra’s resin-forward buds and large capitate-stalked trichomes are favorable for ice-water hash and solventless rosin. Well-grown material with 2% to 3% total terpene content often translates to a strong, flavorful rosin in the 15% to 25% return range depending on micron selections. A cold, controlled wash preserves the citrus-incense high notes that define the strain’s identity.
Throughout, the guiding principle is consistency. Maintain stable temperatures, humidity, and light intensity, and avoid large swings that stress the plant. When aligned with the strain’s mostly indica physiology, these parameters allow Kush of Ra to express its full aromatic and resin potential.
