Written by Ad OpsOrigins and Breeding History
Mr. Jekyll Kush is a mostly indica cultivar developed by the Spanish breeder Mr. Hide Seeds, a company known for crafting robust photoperiod and autoflower lines for the European market. The strain’s name nods to the duality of Dr. Jekyll and Mr. Hyde, hinting at a profile that can feel calm and composed at low doses yet profoundly heavy and introspective at higher doses. While many Kush lines trace to the Hindu Kush mountain range, Mr. Jekyll Kush is presented by its breeder simply as a Kush-forward, indica-leaning variety.
Public breeder notes and retailer listings consistently classify Mr. Jekyll Kush as predominantly indica, which informs expectations about its growth pattern and effects. Indica-dominant Kush varieties are favored for their dense floral clusters, compact stature, and resin saturation that performs well for both flower and extraction. These same traits make Mr. Jekyll Kush attractive to home growers who want manageable plants that finish in a typical 8–9 week flowering window indoors.
In markets where it appears, Mr. Jekyll Kush is positioned as a dependable, resin-driven option rather than a novelty. The emphasis is on predictable morphology, forgiving cultivation parameters, and a terpene footprint most consumers recognize as Kush: earthy, spicy, and piney with occasional sweet or citrusy top notes. This reliability, more than any hype, is what keeps the cultivar in rotation among growers who appreciate practical, repeatable results.
Genetic Lineage and Indica Heritage
Mr. Jekyll Kush’s precise parentage has not been widely published by the breeder, but it is presented as a mostly indica Kush hybrid. In practice, that typically implies genetic input from Afghan or Hindu Kush lines, sometimes hybridized with Skunk or modern Kush derivatives to stabilize vigor and terpene output. This framework explains the strain’s compact structure, robust branching, and heavy resin production compared with lankier sativa-dominant varieties.
Indica-dominant Kush strains have a long track record of producing dense, broad-shouldered colas under moderate feeding and conservative canopy heights. Compared with tall, high-internode sativas, indicas can complete flower in 55–65 days, a 15–25% shorter cycle that matters for commercial turnovers and small tent growers. Mr. Jekyll Kush fits into this tempo, typically finishing within the 8–9 week indoor window and beating autumn rains in many outdoor regions.
From a consumer standpoint, the indica heritage signals an effect curve that prioritizes body relaxation, pressure relief, and a tranquil comedown. The terpene ensemble also aligns with classic Kush signatures: myrcene, beta-caryophyllene, and limonene commonly lead, with humulene and pinene adding earth, spice, and conifer. These shared traits help explain why Kush cultivars consistently appear among top sellers in legal markets, often accounting for a large portion of the “indica” category offerings.
Appearance and Plant Structure
Mr. Jekyll Kush exhibits the hallmarks of an indica-dominant phenotype: medium stature, thick lateral branches, and tight internodal spacing. Leaves are broad with dark green leaflets that can gain anthocyanin highlights—purples and blues—when nighttime temperatures drop 5–8°C below daytime during late bloom. The calyx-to-leaf ratio is typically favorable, making hand-trimming faster and machine trimming less likely to scuff trichome heads.
The colas form into chunky, golf-ball to soda-can-sized clusters depending on training and light intensity. Under strong indoor lighting, flowers often stack with minimal stem between nodes, producing the solid, weighty structure Kush growers prize. The pistils start cream to light orange and darken to amber or rust as the crop nears physiological maturity.
A heavy blanket of glandular trichomes is common, evident as a frosted sheen that looks wet under direct light. This resin density is an indicator of both potency potential and extraction suitability, whether for dry sift, ice water hash, or hydrocarbon processes. Growers often report minimal fox-tailing under controlled temperatures, though excessive heat or high EC late in bloom can still trigger stress morphology.
Aroma and Bouquet
The bouquet of Mr. Jekyll Kush leans earthy and spicy at the base, with pine resin and faint fuel weaving through the mid-notes. Citrus highlights, especially lemon-lime tones, can appear on vigorous phenotypes, adding brightness to the otherwise grounded Kush core. When properly cured, the jar reveals a layered scent that intensifies as the buds are broken apart.
Dominant aromatic contributors are typically myrcene, beta-caryophyllene, and limonene, a trio that many Kush lovers recognize immediately. Myrcene supports the musky, herbal foundation; caryophyllene adds black pepper and warm spice; limonene etches in the citrus top note that reads as clean and crisp. Sub-dominant terpenes like humulene and alpha-pinene reinforce the forest-floor and pine needle accents.
In objective lab datasets from legal markets, total terpene content in commercial flower commonly ranges from 1.0% to 3.5% by weight, with many Kush cultivars clustering around 1.5–2.5%. Mr. Jekyll Kush fits within this envelope in typical conditions, with aroma intensity rising notably between week 6 and harvest. Cool, slow drying and a 2–4 week cure can increase perceived complexity by allowing volatile fractions to equilibrate in the flower.
Flavor and Mouthfeel
On the inhale, Mr. Jekyll Kush delivers a mouth-coating wash of earthy resin and pine, often punctuated by a peppery tickle from beta-caryophyllene. The exhale tends to round into hash-forward spice with a faint citrus pith note that lingers on the palate. Well-cured batches can leave a clean, woody aftertaste reminiscent of cedar and conifer.
In combustion, the smoke is moderately dense and can provoke a light cough in higher-temperature hits due to terpene and resin volume. Vaporization at 175–190°C typically highlights the limonene and pinene top notes, reading brighter and less hashy than smoking. As temperature rises toward 200°C, the profile skews spicier, and the body-heavy effects become more pronounced.
Palate consistency improves with a slow dry—10 to 14 days at 55–60% RH—because rapid drying can mute citrus volatiles and push the profile toward generic earth. Many users find that a 62% cure for 3–6 weeks unlocks a sweeter, more nuanced finish. The end result is classic Kush in spirit: assertive, resinous, and satisfying across roll, pipe, and vape formats.
Cannabinoid Profile and Potency
Mr. Jekyll Kush is generally regarded as a THC-forward cultivar with low intrinsic CBD, consistent with the majority of indica-dominant Kush lines. In legal market lab data sampled across many Kush varieties, THC commonly spans 18–24% by weight, with outliers above 25% under optimal conditions. CBD is typically under 1%, while minor cannabinoids like CBG often appear in the 0.2–1.0% range.
Real-world potency is influenced by environmental conditions and harvest timing, and it is normal to see ±2–3 percentage point variation in lab results between phenotypes or cultivation runs. Higher light intensity, stable VPD, and appropriate nutrient strength during mid-bloom are positively correlated with cannabinoid density. Conversely, heat stress or late flower nutrient imbalance can depress total cannabinoids by several percentage points.
For consumers, potency perception is not only about THC percentage; terpene load and the specific terpene ensemble shape subjective intensity. Many users report that a 20% THC Kush with 2.0% total terpenes can feel subjectively stronger than a 24% THC batch with 0.8% terpenes. This interaction is one reason careful curing and storage—dark, cool conditions at 55–62% RH—help maintain both flavor and perceived potency over time.
Terpene Spectrum and Aroma Chemistry
Across large datasets in legal markets, myrcene is frequently the most common dominant terpene, and Kush strains often follow that trend. In Mr. Jekyll Kush, growers and consumers most often report a myrcene-caryophyllene-limonene triad, with humulene and pinene supporting. Typical total terpene content for well-grown, resinous indicas runs around 1.5–2.5% by weight, though environment and post-harvest handling can shift that by 0.5–1.0%.
Myrcene contributes musky, herbal tones and has been associated in user reports with heavier body sensations when present at higher levels. Beta-caryophyllene, a CB2 receptor agonist, layers black pepper spice and may complement anti-inflammatory effects noted in preclinical work. Limonene brightens the aroma with citrus and is often associated with mood elevation and perceived stress relief.
Pinene (alpha and beta) can add crisp pine and may help maintain a sense of clarity in blends otherwise known for heaviness. Humulene deepens the woody, earthy base and is commonly found alongside caryophyllene in hops and many Kush chemotypes. Terpene volatility under heat means consumption temperature matters: lower vape settings emphasize citrus and pine, while higher settings bring out spice and hash notes.
Experiential Effects and User Reports
With inhalation, onset is usually felt within 5–10 minutes, peaking around 30–45 minutes and tapering over 2–4 hours depending on dose and tolerance. Users commonly report immediate loosening of body tension followed by a calm, grounded mood set. At moderate to higher doses, the body load deepens into a couch-friendly state typical of indica-dominant Kush cultivars.
Cognitively, the early phase can feel pleasantly focused or introspective, with a tendency toward stillness as the session progresses. In higher-potency samples, short-term memory and time perception may wobble, so task-heavy or complex activities are best left for another time. Appetite stimulation is frequently noted, often peaking during the comedown.
Side effects are consistent with THC-dominant flower: dry mouth, dry eyes, and in some individuals, transient lightheadedness on standing. Population surveys commonly show 30–60% of users experiencing dry mouth and 20–40% reporting dry eyes with THC-rich products. Anxiety or racy feelings are less common in indica-leaning Kush strains but can appear at high doses or in sensitive users, especially when combined with caffeine.
Potential Medical Uses
Mr. Jekyll Kush’s indica-forward profile and common terpene ensemble make it a candidate for evening use targeting pain, stress, and sleep initiation. Observational cohorts of medical cannabis users frequently report 10–30% reductions in pain intensity after inhalation, with the largest responses in neuropathic and musculoskeletal pain. The sedative-leaning body effects can also support sleep latency reduction, which users commonly describe as falling asleep 15–30 minutes faster compared with baseline.
Beta-caryophyllene’s CB2 activity, in combination with THC, may contribute to perceived anti-inflammatory benefits; this is supported by preclinical models but should be interpreted cautiously in humans. Limonene is often associated with mood uplift, which can be helpful for stress-related dysphoria without energizing the central nervous system excessively. Myrcene-heavy profiles are often preferred by patients seeking muscle relaxation and calm.
For dosing, inhaled routes allow fine titration: 1–2 small puffs, wait 10 minutes, and reassess before additional intake. For oral routes, a conservative starting dose is 1–2.5 mg THC in inexperienced users, titrating by 1–2 mg every 24–48 hours until the desired effect is achieved. Individuals prone to anxiety may find benefit pairing THC with small amounts of CBD (e.g., 1–5 mg CBD per 5–10 mg THC), though Mr. Jekyll Kush itself is not a CBD-rich cultivar.
Comprehensive Cultivation Guide: Environment, Nutrition, and Training
Germination is straightforward using a 24–26°C environment with 90–100% RH and gentle moisture—paper towel or plug methods both work. Seedlings prefer 250–400 PPFD light intensity in the first 7–10 days and a mild nutrient solution at EC 0.6–0.8 with pH 5.8–6.0 for hydro/coco or 6.2–6.5 in soil. Transplant once the first true leaves spread and roots begin to circle the plug or cup.
In vegetative growth, Mr. Jekyll Kush responds well to topping or FIM and low-stress training to create an even canopy. Typical veg conditions are 24–28°C with 60–70% RH early, stepping to 55–65% RH as plants size up, corresponding to a VPD of roughly 0.8–1.1 kPa. Light intensity in veg can range from 400–600 PPFD over 18 hours, delivering 25–38 mol DLI.
For nutrients, aim for EC 1.4–1.8 in veg with balanced N-P-K and adequate calcium and magnesium, especially in coco and RO water scenarios. Silica at 50–100 ppm can strengthen cell walls and improve stem robustness under heavy colas. Keep pH stable: 5.8–6.2 in hydro/coco and 6.2–6.8 in soil to optimize nutrient availability.
Transition to flower with a 12/12 photoperiod and raise PPFD to 700–900 for weeks 1–3, then 900–1,200 PPFD for weeks 4–7 if CO2 is ambient. With supplemental CO2 at 900–1,200 ppm, some growers push 1,200–1,500 PPFD; this can increase yield by 15–30% if water, nutrients, and temperature are tuned. Maintain 24–26°C lights-on and 18–22°C lights-off to reduce internode stretch and preserve terpene integrity.
In mid-flower, target a VPD of 1.2–1.5 kPa, corresponding to RH 45–55% at 24–26°C. Mr. Jekyll Kush’s dense inflorescences make airflow essential; use oscillating fans and ensure 2–3 complete air exchanges per minute in tents. Dehumidification is critical late bloom; maintain 42–50% RH to limit botrytis risk.
Feeding in flower can step to EC 1.8–2.2 with a gentle nitrogen pullback after week 3 as potassium and phosphorus increase. Overfeeding in late flower can cause tip burn and terpene dulling, so monitor runoff EC and leaf cues. Consider a 7–14 day clear-water finish, keeping pH within range to avoid micronutrient lockout.
Training methods that suit Mr. Jekyll Kush include mainlining, SCROG, and simple LST with one or two toppings. Because the plant tends to stay compact, a single topping at the fifth node followed by lateral tie-downs can fill a 2x2 ft (60x60 cm) space effectively. In sea-of-green setups, run more plants per square meter with minimal veg to capitalize on rapid flowering and tight stacking.
Outdoors, the cultivar prefers a warm, dry-to-moderate Mediterranean climate. In the Northern Hemisphere, transplant after last frost and expect a finish from late September to early October at latitudes 40–45°, sooner at lower latitudes. In humid regions, greenhouse protection and aggressive defoliation around weeks 4–6 of flower reduce mold risk substantially.
Integrated pest management should begin in veg: weekly inspections, sticky cards, and preventive sprays with biologicals like Bacillus subtilis or Beauveria bassiana per label directions. Indica canopies can invite spider mites and powdery mildew if airflow is poor; maintain good hygiene and avoid chronically high RH. Prune interior growth to improve light penetration and drying rates within the canopy.
Phenotypes, Stability, and Seed Selection
From seed, indica-leaning Kush lines commonly present two to three recognizable phenotypic expressions. One leans sweeter and citrus-forward with slightly lighter green foliage, while another trends earthier and spicier with darker leaves and thicker calyx walls. Both fall within the core Kush spectrum, but the citrus-leaning expression can feel marginally brighter in the head at equivalent doses.
Select for structural integrity first: strong apical dominance that still responds to topping, and branches that can bear weight without excessive staking. Resin coverage visible to the naked eye by week 5 is a good filter; an early frost usually correlates with robust terpene output by harvest. Avoid phenotypes that fox-tail early under normal temperatures, as they may be more sensitive to heat or nutrient intensity.
When hunting for a keeper, cure samples for at least 21 days before making final judgments. The terpene shape and mouthfeel can change noticeably during weeks 3–5 of curing, and what seems overly earthy at day 10 may resolve into a balanced Kush profile at day 28. Once selected, clone mothers from lower, mature branches for faster rooting and more uniform lateral growth.
Harvest Timing, Drying, and Curing
Mr. Jekyll Kush generally matures in 8–9 weeks of flower indoors, though some phenotypes can be ready a few days earlier. For a balanced effect, harvest when trichomes are mostly cloudy with 5–10% amber heads; for a heavier, more sedative effect, wait for 15–30% amber. Pistil color is a secondary indicator—look for widespread browning and recession into the calyx, not just surface oxidation.
Drying should be cool and slow to preserve volatile terpenes: 18–20°C and 55–60% RH with gentle airflow for 10–14 days. Avoid direct fans on the flowers and keep the room in darkness to limit terpene oxidation and chlorophyll photodegradation. Target a stem snap on medium branches as your cue to buck or trim and move to cure.
Curing in airtight containers at 58–62% RH stabilizes moisture and completes the flavor. For the first week, burp jars daily for 10–15 minutes, then taper to two or three times weekly for weeks two and three. Many growers notice the bouquet becomes more complex between days 21 and 35, and total terpene perception may improve even if measured totals remain constant.
Yield Expectations and Production Metrics
Indoors, Mr. Jekyll Kush can produce 450–550 g/m² under 600–700 watts of quality LED or HPS in a dialed environment. With CO2 enrichment and high PPFD, skilled growers can push toward 600+ g/m², particularly in SCROG with an even canopy. Grams per watt typically range from 0.8–1.2 for standard rooms and can reach 1.4–1.6 in optimized environments.
Outdoors, individual plants in large containers or raised beds, given full sun and proper nutrition, can yield 600–900 g per plant. In-ground plantings with extended veg and trellising can exceed 1 kg in ideal climates, though humidity control becomes critical. Dense flower structure means proper staking or netting helps prevent lodging and branch splits late in bloom.
For extractors, adequately grown Kush cultivars often return 15–25% rosin from dried flower and 3–6% from fresh-frozen ice water hash-to-rosin, depending on maturity and wash technique. Hydrocarbon extraction yields for resinous Kush lines can land in the 18–25% range. Total terpene content around 1.5–2.5% by weight is a practical target for aromatic, market-ready flower.
Post-Consumption Tips and Responsible Use
Because Mr. Jekyll Kush trends sedative at moderate to high doses, plan sessions for late afternoon or evening. Avoid driving or operating machinery while under the influence; impairment can persist for several hours, and residual effects may linger into the next day at high doses. Hydrate before and after use to mitigate dry mouth and eyes, and consider a light snack if you are prone to dizziness.
Tolerance builds with frequent high-THC use; many consumers regain sensitivity after a 3–7 day tolerance reset. If anxious feelings emerge, reduce dose size, lower consumption temperature for vaporization, and consider pairing with a calming activity in a familiar setting. Individuals with cardiovascular concerns, pregnancy, or medication interactions should consult a clinician familiar with cannabinoids.
Store flower in airtight, opaque containers at cool room temperature and 55–62% RH to preserve potency and terpenes. Heat and light accelerate degradation; THC can oxidize to CBN over time, shifting effects further sedative. Label jars with harvest date and phenotype notes to track how the profile evolves during curing and storage.
