KC36 Haze is a modern Haze-forward hybrid bred by Sunny Valley Seed Co., created for cultivators and consumers who want classic, high-energy Haze character in a more manageable, faster-finishing package. The strain marries the uplifting, citrus-and-incense profile of Haze with the compact structure and earlier ripening tendencies associated with the KC36 side of its heritage. The result is a plant that can be steered to medium height indoors, with abundant lateral branching and a high calyx-to-leaf ratio that rewards careful pruning and training.
In practical terms, KC36 Haze is designed to bridge the gap between boutique sativa lovers and production-focused growers. Haze-dominant plants are notorious for long bloom cycles, but breeder selection by Sunny Valley Seed Co. targets a 9–11 week indoor flowering window under 12/12. Indoors, trained plants commonly return 450–650 g/m², while outdoor, long-season gardens can surpass 700 g per plant with attentive canopy management.
On the consumer side, KC36 Haze leans cerebral, bright, and creative, with a terpene ensemble led by terpinolene, limonene, and myrcene in many phenotypes. Typical lab ranges for Haze-leaning hybrids suggest THC in the high teens to low 20s, and early reports for KC36 Haze are consistent with that band. The overall effect profile trends toward daytime use, with a clear, motivational arc and a comparatively gentle body load for a hybrid of its vigor.
Breeding History and Origins
Sunny Valley Seed Co. developed KC36 Haze with a clear goal: preserve the soaring, euphoric, and aromatic complexity of Haze while trimming both plant height and flowering length. Haze genetics are celebrated for their effect but can test a grower’s space and patience; the KC36 influence was chosen to moderate those traits. This approach reflects a broader industry trend of hybridizing classic sativas with compact, earlier-flowering partners to increase accessibility without losing the signature Haze experience.
Rather than producing a radically reworked Haze, Sunny Valley Seed Co. appears to have focused on stabilizing a phenotype balance that retains sativa vigor and terpenes. Breeder descriptions and grower observations point to internodal spacing that’s a touch tighter than landrace-influenced Hazes, with stems selected for better load-bearing strength. These choices pay dividends in indoor tents where ceiling limits make true Haze trees impractical.
While exact release dates and filial generation designations are proprietary, the strain behaves in line with a modern Haze-dom hybrid that has been selected across several rounds. Expect a degree of phenotypic spread that lets growers choose between a more electric Haze expression and a slightly denser, faster KC36-leaning expression. That controlled variability can be an advantage in pheno hunts targeting terpene intensity versus turnaround time.
Genetic Lineage and Phenotypic Variability
KC36 Haze is widely described as a cross between a compact, quick-finishing KC36 parent and a classic Haze-leaning selection. The KC36 side provides earlier ripening, tighter nodal spacing, and chunkier calyx stacking, while the Haze side contributes the terpene complexity and the bright, cerebral high. Sunny Valley Seed Co.’s selection pressures emphasize keeping the Haze top notes intact while shaving a week or more off a typical Haze bloom.
Growers commonly report two dominant expressions across small pheno hunts: a Haze-forward phenotype and a balanced or slightly KC36-forward phenotype. In a 10-seed indoor run, it is not unusual to see roughly a 60:40 split favoring the Haze-leaning expression, though actual ratios vary by pack and environment. The Haze-leaning plants stretch 1.8–2.2× after flip under high PPFD, while balanced phenos stretch closer to 1.4–1.7× and develop denser mid-colas.
Chemically, terpinolene-dominant chemotypes appear frequently in Haze-forward expressions, followed by limonene and α-pinene as secondary drivers. Balanced phenos can tilt toward myrcene and β-caryophyllene, shifting the nose from pine-citrus-incense to a more citrus-herbal-skunk framework. This chemotypic spread offers choice: a zesty, uplifting profile for daytime or a slightly warmer, more rounded profile that’s gentler for new Haze users.
Appearance and Morphology
KC36 Haze exhibits medium-tall architecture with strong apical dominance that responds well to topping. Internodal spacing on the Haze-leaning phenos averages 5–8 cm under adequate light and low nitrogen late in stretch, compared to 3–6 cm in the KC36-leaning phenos. Leaves tend to be mid-narrow with pronounced serrations, signaling the sativa influence without going fully slender.
Flower clusters are conical with a tendency to develop elegant foxtailing toward late bloom if PPFD is very high or if the room runs warm. Calyx-to-leaf ratios are favorable, often around 2.5:1 to 3:1, making trim sessions efficient and preserving resin-heavy bracts. Mature pistils fade from bright tangerine to russet as the trichomes cloud up, with sugar leaves dusted by milky heads that reinforce a frosty sheen.
Under optimal conditions, the plant maintains good stem rigidity, with lateral branches strong enough to support colas once light defoliation and modest trellising are applied. Average indoor height from a 4–5 week veg and topping twice is 90–130 cm, depending on pot size and training. Outdoors in ground, plants can reach 180–250 cm in a long season, provided wind and support are adequate to prevent lodging.
Aroma Bouquet
The nose on KC36 Haze is citrus-forward with a bright, sweet top note of lemon zest and lime leaf. Beneath that sits a resinous pine and herbal facet reminiscent of bay laurel and basil, often accompanied by a faint floral-incense quality. The Haze heritage is unmistakable at the grind, where the terpinolene spark and a touch of sweet wood lift from the jar.
As flowers mature and cure, secondary spices emerge: cracked pepper from β-caryophyllene, a hint of anise from phellandrene in some phenos, and a light lavender twist when linalool is present. Freshly broken buds typically project 7–9 feet across a room, and total terpene concentrations of 1.5–2.5% by weight are common for Haze-leaning hybrids harvested and cured correctly. In balanced phenos, a skunky-citrus backbone underscores the bouquet, giving the aroma a slightly muskier depth without losing brightness.
Aromatics are sensitive to drying conditions; a slow cure preserves the citrus and pine while preventing the top notes from volatilizing. If dried too warm or too fast, citrus fades by as much as 30–40% in perceived intensity, leaving the spicier base notes more dominant. Proper jar conditioning rebalances the profile and elevates the incense-like tail that many Haze enthusiasts prize.
Flavor Profile
On the palate, KC36 Haze delivers lemon oil, sweet lime, and a brisk pine snap that lands early on the tongue. The mid-palate often brings basilic herb, green mango, and a faint floral sweetness, especially in jars cured for 3–4 weeks. The finish trends peppery and slightly woody with a lingering citrus pith that keeps the profile crisp rather than sugary.
Vaporization at 175–190°C tends to highlight terpinolene, ocimene, and limonene, producing a bright, effervescent inhale with a clean exhale. At higher temperatures around 200–205°C, the pepper-spice of β-caryophyllene and the soothing glide of linalool become more noticeable, rounding the edges of the citrus. Combustion retains the lemon-pine character, though repeated high-heat pulls can mute the top notes faster than gentle sips.
Flavor stability improves after a slow dry (10–14 days at ~60% RH and 60°F/15.5°C) followed by a 4–6 week cure. In blind tastings among experienced consumers, citrus-forward Haze hybrids consistently score higher for perceived “freshness,” and KC36 Haze follows that pattern. Pairing with terpene-complementary foods like citrus, rosemary, or light-roast coffee can accentuate the palate cues the strain naturally provides.
Cannabinoid Profile and Potency
Based on typical outputs for Haze-dominant hybrids and early grower reports, KC36 Haze commonly tests in the 18–24% THC range when well-grown and properly cured. Outlier phenotypes and dialed-in environments can occasionally push into the mid-20s THC, while less optimized runs may land in the mid-teens. CBD is generally low, often below 0.5%, keeping the overall chemotype squarely THC-dominant.
Minor cannabinoids help shape the effect contour. CBG frequently appears in the 0.2–0.8% range, contributing to a smoother onset and perceived clarity. Trace THCV is possible, particularly in Haze-influenced chemotypes, often at 0.1–0.7%, which some users associate with a brisk, energetic tone.
Expressed in mg/g, a representative KC36 Haze lab result might show THC 180–240 mg/g, CBD 0–5 mg/g, CBG 2–8 mg/g, and THCV 1–7 mg/g, with the remainder occupied by other acidic and neutral cannabinoids and terpenes. Total cannabinoid content typically falls between 20–28% by weight across robust indoor harvests. As always, actual values depend on phenotype, cultivation practices, and post-harvest handling, which can swing potency by 10–20% from batch to batch.
Terpene Profile and Chemistry
KC36 Haze’s terpene spectrum is led by terpinolene in many Haze-forward phenos, with limonene, myrcene, and α-pinene frequently appearing as co-dominant or secondary terpenes. Total terpene content generally ranges from 1.2–2.6% by dry weight in optimized runs, with the brightest jars clustering around 1.8–2.2%. Balanced phenos may substitute a touch more myrcene and β-caryophyllene, nudging the profile toward citrus-herbal with a spiced base.
Indicative ranges observed in Haze-leaning hybrids—and applicable to KC36 Haze—are: terpinolene 0.20–0.70%, limonene 0.15–0.50%, myrcene 0.20–0.50%, β-caryophyllene 0.10–0.35%, α-pinene 0.06–0.20%, ocimene 0.05–0.20%, and linalool 0.03–0.12%. These compounds map neatly to the aroma and flavor notes: terpinolene brings citrus-pine sparkle, limonene adds lemon-lime lift, and pinene contributes the foresty, clarifying edge. Caryophyllene anchors the spice and interacts with CB2 receptors, while linalool adds a gentle floral calm in select phenos.
Maintaining terpene integrity is highly sensitive to post-harvest conditions. At 60°F/60% RH, terpene loss over a 10–14 day dry can be kept below 15–20%, whereas warmer, drier cures can drive losses exceeding 30%. Glass storage at 58–62% RH with minimal headspace helps stabilize the ratios, preserving the signature Haze brightness that defines KC36 Haze.
Experiential Effects
KC36 Haze delivers a fast, lucid lift that many describe as energetic, sociable, and creatively stimulating. The initial onset after inhalation is typically felt within 3–8 minutes, with a gentle ramp to a clear peak around 35–60 minutes. Duration of noticeable effects commonly stretches 2–3 hours for experienced users and longer for low-tolerance individuals.
Aggregated user impressions for Haze-leaning hybrids indicate 65–75% report uplifted mood, 50–60% increased creativity, and 40–55% improved focus at moderate doses. Body effects are present but secondary, often described as a light, tension-relieving float rather than heavy sedation. At higher doses, 10–20% of THC-sensitive users report racy moments or transient anxiety, a known pattern with bright, terpinolene-forward profiles.
The balanced KC36-leaning phenos tend to soften the edge, with a smoother emotional curve and slightly more body grounding. Music, outdoor walks, and brainstorming sessions are common context fits, while deep couch sessions or late-night wind downs may not be the best match. As always, set and setting influence the experience—hydration, nutrition, and dose pacing make a measurable difference in comfort and clarity.
Dosage, Tolerance, and Consumption Methods
For new consumers, starting with 2.5–5 mg THC orally or 1–2 small inhalation puffs is a prudent approach. Experienced consumers often find 5–10 mg THC orally or 2–4 puffs sufficient for daytime creativity without tipping into overstimulation. Tolerance accrues with frequent use; spacing sessions by 24–48 hours can noticeably restore sensitivity for many users.
Inhalation offers faster titration and more control over onset; vaporization at 180–190°C is recommended to emphasize the citrus-pine top end. Edibles produce a slower, longer arc—onset around 45–90 minutes, peak at 2–3 hours, and tail up to 6 hours—so dose conservatively with KC36 Haze if you’re prone to overconsumption. Sublingual tinctures can split the difference with partial first-pass metabolism and a more predictable curve.
Hydration and a small snack can mitigate dry mouth and lightheadedness, which 30–40% of users report with THC-dominant chemovars. For those sensitive to stimulation, pairing KC36 Haze with calming activities or mixing with a small percentage of CBD flower (e.g., 1:4 CBD:THC) may smooth the ride. Avoid combining with other stimulants like high-dose caffeine if you are prone to jitters.
Potential Medical Applications and Considerations
KC36 Haze’s uplifting profile makes it a candidate for daytime symptom management where energy, mood, and motivation are priorities. Users commonly report benefits for low mood, fatigue, and task engagement, consistent with survey data showing sativa-leaning hybrids are chosen for daytime use by a majority of respondents seeking mood elevation. The focus-enhancing quality some experience can be useful for creative work, though it can be too stimulating for individuals prone to anxiety.
β-caryophyllene’s CB2 activity suggests potential anti-inflammatory support, while limonene and pinene have been associated with mood and alertness in aromatic studies. This chemistry aligns with anecdotal relief for tension headaches, mild neuropathic discomfort, and stress-related somatic tightness. That said, medical responses vary, and clinical evidence for specific conditions remains limited compared to anecdotal reports.
Potential adverse effects include dry mouth, dry eyes, transient anxiety, and in rare cases dizziness, particularly at higher doses or in unfamiliar environments. Individuals with a history of panic, arrhythmia, or sensitivity to stimulants should start low and proceed slowly. This information is educational and not medical advice; patients should consult a qualified healthcare professional to tailor cannabinoid and terpene profiles to their needs.
Comprehensive Cultivation Guide: From Seed to Harvest
Sunny Valley Seed Co. bred KC36 Haze for growers seeking Haze character with a cultivation curve that doesn’t overwhelm. Germination is straightforward: 24–36 hours soak-and-towel methods routinely reach 90%+ viability with fresh seed, and root emergence by day 2–3 is typical in a 24–26°C environment. Transplant into a light, airy substrate and maintain moderate moisture rather than saturation during the first 10 days to promote lateral root branching.
KC36 Haze thrives in coco coir, soilless blends, and well-aerated living soil with ample oxygenation. For coco and hydro, target a pH of 5.8–6.2; for soil, 6.2–6.8 keeps micronutrients available without encouraging excess cation lockout. Aim for 300–500 PPFD in early veg, rising to 500–700 PPFD by late veg, and 700–1,000 PPFD in bloom, adjusting CO2 and temperature accordingly.
Photoperiod plants prefer 4–5 weeks of vegetative growth for strong branch scaffolding before flip. Expect 1.5–2.2× stretch depending on phenotype and intensity, so implement training before the first week of flower. A single trellis net or bamboo stakes are usually sufficient if you prune lower growth and maintain airflow to the interior of the canopy.
Environmental Parameters and Lighting Strategy
Vegetative targets of 24–28°C with 60–70% RH (VPD ~0.8–1.1 kPa) support rapid leaf expansion without overtaxing transpiration. In early flower, shift to 24–26°C and 55–60% RH (VPD ~1.1–1.3 kPa) to encourage vigorous floral initiation. By mid-to-late flower, 22–25°C and 45–50% RH (VPD ~1.3–1.5 kPa) help reduce botrytis risk while maintaining resin output.
Daily Light Integral (DLI) targets of 30–40 mol/m²/day in veg and 35–45 mol/m²/day in flower are effective for KC36 Haze under LED. With supplemental CO2 at 1,000–1,200 ppm, PPFD can be raised 10–20% in flower to drive additional biomass, provided root-zone oxygen and nutrition keep pace. Watch for foxtailing at PPFD >1,100 µmol/m²/s if room temperature or calcium availability are not tuned.
Airflow is critical for Haze-leaning structures; plan for 0.3–0.5 room air exchanges per minute and gentle, oscillating fans sweeping across and under the canopy. Keep canopy leaf surface temperatures measured by IR within 1–2°C of ambient to avoid hidden heat stress under high-intensity LEDs. Nighttime temperature dips of 2–3°C maintain metabolic balance without sacrificing terpene retention.
Nutrition, Irrigation, and pH/EC Management
KC36 Haze prefers steady nutrition rather than aggressive spikes, particularly with nitrogen during the transition to flower. In veg, aim for 120–160 ppm N, 40–60 ppm P, and 160–220 ppm K, with Ca:Mg around 3:1 and supplemental Si at 50–100 ppm for stem strength. In bloom, taper N to 80–120 ppm by week 3–4, while increasing P to 50–70 ppm and K to 220–300 ppm to support calyx production and enzyme function.
For coco/hydro, EC in veg of 1.2–1.6 mS/cm and in bloom of 1.6–2.2 mS/cm is a solid range, with runoff monitored to avoid salt accumulation. Soil and living soil growers can top-dress or use teas, but should avoid overwatering—a 10–20% dry-back between irrigations promotes oxygenation and discourages fungus gnats. Keep irrigation solutions at 18–21°C to maintain dissolved oxygen and avoid root stress.
KC36 Haze shows a mild sensitivity to excessive ammoniacal N and late-swell P-K overdoses, which can darken leaves and suppress terpene expression. Magnesium supplementation at 40–60 ppm during high-PPFD runs prevents interveinal chlorosis under LED-heavy spectra. A 10–14 day low-N finish with ample Ca, Mg, and micronutrients promotes a clean burn and preserves top-end aromatics.
Training, Canopy Architecture, and Stretch Control
Top early at the 4th–5th node and sculpt 6–10 primary sites for a balanced, scrog-friendly canopy. Low-stress training (LST) combined with a single topping can produce a flat, well-lit plane that minimizes larf and controls the Haze stretch. Supercropping can be used sparingly in week 2–3 of flower to redirect energy if vertical clearance becomes a concern.
Defoliation should be strategic: remove interior fans that shade bud sites and impede airflow, but avoid stripping more than 20–25% of leaf area at once. Execute a light thinning at day 18–21 after flip and another touch-up around day 35–42 if needed, keeping stress low during the swell. The KC36 influence supports sturdier lateral scaffolding, but a trellis net greatly reduces risk of mid-flower stem kinks.
For high-density gardens, sea-of-green (SOG) with smaller plants can also work, but ensure each plant has room to express its lateral growth. Spacing of 0.25–0.35 m² per plant under scrog and 0.15–0.20 m² per plant under SOG are good starting points, adjusting to phenotype. Maintaining an even canopy within ±5 cm of height variance helps maximize uniform PPFD and consistent ripening.
Flowering Time, Yield Expectations, and Harvest Indicators
KC36 Haze typically completes in 63–77 days of 12/12 indoors, with Haze-leaning phenos closer to 70–77 days and balanced phenos finishing in 63–70 days. Outdoor in temperate zones, harvest windows often fall from early to mid-October, depending on latitude and fall weather. The shortened timeline compared to many Hazes is a key advantage conferred by Sunny Valley Seed Co.’s selection.
Indoor yields of 450–650 g/m² are realistic under optimized LED lighting and CO2, with 350–450 g/m² common in simpler, non-CO2 setups. Outdoor plants, when grown in 100–200 L containers or in-ground beds, can produce 700–1,200 g per plant with strong sun, supportive nutrition, and wind protection. Buds are medium-dense, resin-rich, and trim efficiently thanks to favorable calyx stacking.
For harvest timing, watch trichomes: a balanced, energetic effect is often captured at ~5–10% amber with the majority cloudy. If a more relaxed finish is desired, allow 10–15% amber, but going beyond that can mute the sparkling clarity Haze fans seek. Aromatic peak often coincides with sticky, terp-rich bracts and a shift in pistil color from tangerine to russet, signaling an ideal window.
Post-Harvest: Drying, Curing, and Storage
Dry KC36 Haze slowly at 60°F/60% RH for 10–14 days, targeting a uniform stem snap without case-hardening. This regimen limits terpene volatilization and preserves the delicate citrus and pine top notes that define the profile. Avoid oscillating RH by more than ±5% during dry, which can lead to chlorophyll lock and diminished flavor.
Cure in airtight glass at 58–62% RH for 4–8 weeks, burping gently during the first 10–14 days to exchange humid air. Water activity in the 0.55–0.65 range is ideal for stability while preventing microbial growth. Properly cured KC36 Haze shows a notable increase in sweetness and a smoother, less astringent finish by week three.
Storage in cool, dark conditions extends shelf life; every 10°C increase approximately doubles the rate of terpene loss (a Q10 effect seen in volatile compounds). Keep jars at 15–20°C and out of UV to retain color and resin integrity. For long-term storage beyond three months, nitrogen flushing and minimal headspace help maintain chemistry and sensory quality.
Integrated Pest and Disease Management
KC36 Haze’s semi-open structure improves airflow, but its resin-rich flowers still require vigilant IPM, especially late bloom. Start clean with preventative biologicals such as Bacillus subtilis for foliar disease suppression and Beauveria bassiana or Isaria fumosorosea as part of a rotation for soft-bodied pests. Predatory mites like Neoseiulus californicus and Amblyseius swirskii at 1–2 per square foot early in veg help suppress thrips and mite populations before they escalate.
Maintain sanitation with weekly leaf inspections and sticky cards at canopy height and near intakes. Powdery mildew risk rises if RH and leaf-wetness increase; keep VPD within targets, avoid night-time condensation, and ensure gentle airflow across bud sites. Bud rot (Botrytis) becomes a concern in late flower for larger colas; pruning interior fluff and maintaining RH ≤50% in the final weeks significantly reduces risk.
If infestation occurs, escalate with targeted biocontrols and mechanical removal rather than harsh chemistries, particularly after week 3 of flower. Always vet any product for post-harvest safety and local compliance. A clean start and consistent monitoring remain the most statistically impactful strategies for minimizing crop loss in high-value cultivars.
Outdoor and Greenhouse Considerations
KC36 Haze performs best outdoors in Mediterranean or semi-arid climates where fall rains are limited. In temperate zones with early autumn moisture, greenhouse cultivation with dehumidification is preferred to protect late-season trichome development. Plant in rich, well-draining beds amended with 20–30% aeration and compost, targeting a slightly acidic soil pH of 6.3–6.7.
Full sun exposure (8–10 hours direct light) drives yields and terpene density; reflective mulches can increase canopy PAR by 5–10% in tightly spaced gardens. Staking or trellising is recommended once plants exceed 120 cm to prevent wind breakage, particularly for Haze-leaning phenos with elongated colas. Drip irrigation with 15–25% dry-back cycles stabilizes root-zone oxygen and reduces fungal risk compared to overhead watering.
For season extension, consider light dep to finish by late September in wetter regions. Greenhouse PPFD targets of 600–800 in flower are attainable with supplemental LEDs on overcast days, preventing stretch and maintaining tight internodes. Outdoor yields of 800–1,200 g per plant are attainable in long seasons with strong sun, vigilant IPM, and steady nutrition.
Final Thoughts
KC36 Haze, bred by Sunny Valley Seed Co., captures the essential thrill of Haze—citrus brightness, piney sparkle, and an up-tempo, creative energy—while solving practical issues that kept many growers at arm’s length. The shortened 9–11 week bloom, improved stem strength, and manageable stretch make it a realistic choice for indoor rooms and modest tents alike. Consumers who love a clear, motivated headspace without heavy sedation will find KC36 Haze a compelling daytime companion.
From a cultivation standpoint, the strain responds predictably to topping, scrog, and moderate defoliation, and it rewards careful environment control with excellent resin and aroma. Horticultural metrics like 700–1,000 µmol/m²/s PPFD in flower, 45–50% RH late bloom, and balanced Ca/Mg delivery correlate with top-quality outcomes. Post-harvest discipline—60/60 drying and a 4–6 week cure—locks in the sensory signature that sets this hybrid apart.
Whether you are pheno-hunting for a terpinolene-heavy jar with electric clarity or an approachable, citrus-spice expression with a smoother body, KC36 Haze offers a satisfying range. It honors the Haze legacy while being built for modern gardens and real-world schedules. For growers and connoisseurs seeking specificity, vigor, and a data-informed path to success, KC36 Haze delivers on its promise.
