WW x Thai Haze x Skunk #1 is a mostly sativa hybrid developed by TH Seeds, the long-running Amsterdam breeder known for pushing Haze genetics into reliable, garden-ready form. As its name signals, this cultivar blends the crystalline punch of White Widow (often abbreviated WW), the lofty, electric drive of Thai Haze, and the vigorous, classic backbone of Skunk #1. The result is a plant that marries old-school pedigree with modern performance, targeting growers and consumers who want upbeat clarity alongside dense resin and unmistakable skunk-citrus perfume.
The cross leans decisively sativa in structure and effect, yet it still benefits from Skunk #1’s indoor-friendliness and White Widow’s resin-laden, frost-heavy flowers. Expect long, tapering colas that glisten under light, plus a headspace that trends energetic, imaginative, and long-lasting. For many, it lands in a creative daytime lane, with a more grounded finish than pure Haze lines, courtesy of the Skunk and Widow influences.
History and Breeding Background
The Haze family itself originates from 1970s California, where the Haze Brothers and subsequent keepers combined tropical sativas to create the archetype now known simply as Haze. As chronicled in modern strain-family overviews, Haze went on to define a cross-continental moment, bridging California’s landrace experimentation with the disciplined selection work of Dutch breeders. Leafly’s Haze family genealogy describes it as a legendary second-generation strain representing the best of Holland and California—precisely the breeding context in which an Amsterdam outfit like TH Seeds thrives.
Skunk #1, stabilized in the late 1970s and 1980s, brought vigor, faster finishing times, and pungent terpenes that helped indoor cultivation flourish. It also injected a reproducible growth pattern that made once-erratic sativas easier to manage in tents and rooms. White Widow, a 1990s Dutch classic, contributed glittering trichomes and a modern potency ceiling, further consolidating a template for big resin and assertive highs.
By stacking WW with Thai Haze and Skunk #1, TH Seeds pursued a top-to-bottom sativa experience that still kept growers in mind—no endless 16-week flowering or finicky, nutrient-shy plants. The goal is a soaring sativa effect with sweet-citrus floral top notes—consistent with Haze literature that highlights compelling citrus and flowers leading to an upbeat, creative lift—tempered by Skunk’s sturdiness and Widow’s frost. The end product channels the golden-age energy of Haze while remaining realistic for modern production cycles.
Genetic Lineage and Inheritance
White Widow typically contributes dense trichome coverage and a bump to potency, commonly testing in the high teens to low 20s for THC in many markets. It also brings a resin-rich mouthfeel and a freeze-dried look that’s visually obvious in finished flower and concentrates. From a breeding perspective, White Widow’s hybrid vigor can support heavier calyx stacking, which helps correct the airy tendencies of ultra-sativa colas.
Thai Haze introduces narrow-leaf morphology, a longer internodal spacing, and a terpene profile that often leans into terpinolene, limonene, and pinene. Haze family discussions frequently note a sweet citrus-floral bouquet associated with uplifting, creative energy. This branch of the lineage is where the fast-firing euphoria and clear focus most strongly originate, alongside the potential for a prolonged flowering window.
Skunk #1 offers high reliability, predictable branching, and a classic citrus-sweet skunk aroma reported across its descendants, like Super Skunk. Sensi Skunk and Super Skunk references highlight an indica-driven calm and indoor ease, traits that flow upstream in the Skunk family tree. In this tri-cross, Skunk #1 shortens maturation slightly, thickens flower formation, and adds that unmistakable pungency that cuts through the Haze’s high-tone citrus and floral elements.
Appearance and Plant Morphology
Plants generally show a sativa-dominant, Christmas-tree outline with flexible, well-spaced branches that accept training easily. Leaflets are long and blade-like, with 9–13 fingers not uncommon on vigorous specimens, and an emerald-to-lime coloration that stays lighter under high light intensity. Skunk #1’s influence can widen the mid-canopy and encourage lateral branching that fills a screen or trellis with uniform tops.
During bloom, colas form as elongated spears with a high calyx-to-leaf ratio, and White Widow’s legacy becomes obvious in heavy trichome coverage. Under bright LEDs, resin heads stand densely scattered across the bracts and sugar leaves, often producing a frosted, almost chalky-white sheen by weeks 7–9 of flowering. Anthocyanin expression is possible in cooler night temperatures, occasionally imparting faint mauve or lavender streaks to late-stage sugar leaves.
Mature flowers typically exhibit a balance: Haze-leaning phenotypes remain slightly more open and foxtailed, while Skunk-leaning phenos bulk up with tighter node spacing. Average internode distances of 5–10 cm (2–4 inches) are common under optimized lighting. Expect 2–3× stretch after the flip, so pre-flower canopy management is essential to avoid light burn and airflow issues.
Aroma and Bouquet
The nose opens with sweet citrus—think candied orange peel and lemon zest—interlaced with floral tones consistent with Haze family reports. Leafly’s Haze terpene overview emphasizes sweet citrus with a compelling floral note that often precedes an uplifting, creative high. In this cross, that profile is rounded by a skunky, slightly sulfurous base and the faint spicy-herbal tickle of pinene and caryophyllene.
Breaking a cured bud amplifies the sweet-skunk duality: the top end veers toward tangerine and Meyer lemon, while the base notes hint at fresh-cut cedar, pepper, and a clean, musky undertone. Many growers report the room-filling, unmistakable “Haze zest” when the jars are cracked—bright and almost sparkling. Terpene-rich phenotypes can perfume an entire space during trimming, so carbon filtration is recommended in odor-sensitive environments.
Flavor and Palate
On inhale, the flavor skews citrus-forward with a honeyed floral bend, echoing classic Haze character. Vaporizing at lower temps (170–185°C) accentuates the terpinolene-limonene brightness and preserves delicate nerolidol/linalool nuances. As temperature rises, expect more skunk-spice and woody resin to push forward, with caryophyllene supplying pepper and a faint clove impression.
Exhale often lands in citrus pith and dried herbs, followed by a skunky tail that lingers on the palate. Water-cured or long-cured batches can lean more herbal and cedar-toned, trading some top-note zing for depth. Pairing with citrus-forward beverages or lightly sweet teas tends to harmonize the flavor arc and minimize any harshness at higher burn temps.
Cannabinoid Profile and Potency
Given the pedigree, potency commonly lands in the high range for modern flower. Across US legal markets, average retail flower tests cluster around 18–22% THC, with top lots exceeding 25%; this cross can reasonably chart 18–26% THC depending on phenotype and cultivation. CBD is typically low (<1%), with minor cannabinoids like CBG frequently appearing in the 0.1–1.0% band.
The uplifting effect profile aligns with high-THC, terpinolene-forward chemotypes, which many labs and reviewers associate with pronounced head effects. Studies on THC’s acute physiology note a transient increase in heart rate (often +20–50 bpm) and changes in perceived time and sensory salience. Consumers sensitive to strong sativa effects may experience racing thoughts at higher doses, a pattern consistent with Haze-family reports.
Extracts from resin-heavy phenotypes can test even higher for total cannabinoids, with shatter, live resin, or rosin concentrate lots often surpassing 70% total cannabinoids. Because White Widow reliably pushes gland density, this line can be attractive to hashmakers seeking flavorful, bright-leaning profiles. For flower, total terpene content in skilled grows often falls between 1.5–3.0% by weight, though standout lots may exceed that threshold.
Terpene Profile and Volatile Chemistry
Haze-descended cultivars frequently show terpinolene as a lead terpene, supported by limonene, beta-myrcene, and alpha-pinene. Although terpinolene-dominant chemotypes constitute a small slice of US lab results overall (roughly 1–3% in large data sets), they cluster strongly among Hazes and Jacks—matching the reported sweet-citrus floral nose of this cross. Limonene bolsters citrus brightness and can contribute to perceived mood elevation when combined with THC.
Beta-caryophyllene, a sesquiterpene known to interact with CB2 receptors, often shows in the middle of the pack, contributing peppery and woody spice. Alpha- and beta-pinene lend pine resin and can subjectively counteract some THC fogginess for certain users, a phenomenon noted anecdotally by many consumers. Myrcene may be present in moderate amounts; while myrcene is commonly associated with sedation in some contexts, its role here seems more as a fruit-sweet bridge between citrus top notes and skunky base.
Minor terpenes—including ocimene, linalool, and nerolidol—spike in select phenotypes, influencing floral complexity and perceived smoothness. In cured flower from experienced growers, a combined terpene content near 2% is a practical target, with terpinolene frequently commanding the top slot. Fresh frozen material that preserves high terpinolene and limonene can yield live extracts with vivid, sparkling citrus and bouquet-like florals.
Experiential Effects and Use Cases
User reports for Haze family strains consistently emphasize energetic, creative, and uplifted effects, with Leafly summarizing these outcomes alongside occasional negatives like anxiety or dizziness. This tri-cross tracks that pattern closely, offering a fast, clear onset that can stimulate ideation, conversation, or focused tasks. Many describe the feeling as mentally expansive yet linear enough to tackle work sessions, music, or long walks.
The body feel is lighter than indica-leaning hybrids, though Skunk #1’s presence tempers the high with subtle muscle ease after the first hour. As the session progresses, the buzz remains cerebral but gains a mellow undercurrent that avoids full edginess for most users. Doses above individual tolerance, however, can tip into racy territory—a common caution with high-THC, citrus-forward sativas.
For time-of-day, daytime and early evening are ideal for most. Athletically inclined consumers sometimes select similar energizing strains to help fight fatigue—reports compiled on high-energy strain roundups echo this activation. If sensitivity to strong sativas is known, pairing smaller inhalations with hydration and a light snack can keep the experience bright and controlled.
Potential Therapeutic Applications
While individual responses vary, the uplifting and focusing qualities position this cultivar as a potential daytime option for mood elevation. Informal patient feedback for Haze-type sativas often cites increased motivation and creative drive, which may support individuals managing low mood or task initiation challenges. The low CBD and high THC balance, however, means it may not suit everyone, especially those prone to anxiety.
Skunk #1’s indica-driven undertone, as observed in strains like Sensi Skunk, may provide muscle relaxation and stress relief alongside the mental lift. Some users report tension reduction and a softening of physical discomfort, particularly with microdosed or moderate flower sessions. Beta-caryophyllene’s CB2 activity could contribute peripheral soothing effects, though formal clinical conclusions remain limited.
For nausea or appetite, citrus-rich, high-THC profiles sometimes assist when taken at appropriate doses, particularly in the late morning or afternoon. Those sensitive to THC’s cardiovascular effects should consult a clinician and start at very low doses. As always, cannabis is not a substitute for professional medical care; any therapeutic use should be guided by a healthcare provider’s advice and local regulations.
Cultivation Guide: Environment and Setup
Being mostly sativa, WW x Thai Haze x Skunk #1 responds best to fast-growing, high-oxygen root zones and strong, even light. Indoors, target 24–28°C days and 18–22°C nights with relative humidity at 60–70% in veg, stepping down to 45–55% in mid-to-late flower. Follow a VPD guide to maintain leaf-surface vapor pressure within 0.8–1.2 kPa during veg and 1.2–1.5 kPa in bloom.
Under LEDs, aim for 30–40 mol/m²/day DLI in veg and 40–55 mol/m²/day in flower, translating roughly to 500–700 µmol/m²/s PPFD early bloom and 700–900 µmol/m²/s mid bloom for 12 hours. With added CO₂ (900–1,200 ppm), PPFD can be increased to 1,000–1,200 µmol/m²/s, provided irrigation and nutrition are dialed. If CO₂ isn’t supplemented, avoid overshooting light intensity, which can trigger photo-oxidative stress and terpenoid volatilization.
Because stretch can reach 2–3×, plan vertical clearance or employ trellising. A SCROG net or dual-layer trellis helps control canopy and support long Haze-leaning colas. Carbon filtration is recommended: skunk-citrus aromatics can exceed odor thresholds quickly, especially after week 5 of flower.
Cultivation Guide: Nutrition and Irrigation
This line prefers consistent but not excessive nitrogen in veg. Target EC around 1.2–1.5 mS/cm early veg, increasing to 1.6–2.0 mS/cm in peak bloom depending on medium and cultivar response. Maintain ample calcium and magnesium, particularly under LEDs, as higher photon density elevates Ca/Mg demand; supplement with 100–150 ppm Ca and 50–70 ppm Mg if needed.
For coco and hydro, high-frequency fertigation keeps root zones aerobic; 1–3 irrigations per day in early veg can scale to 4–6 small irrigations per day as canopies fill. Aim for 10–20% runoff to prevent salt buildup, with root-zone EC checks at least weekly. In living soil, lean on top-dressed amendments like kelp, fish bone meal, and malted barley, supported by microbial teas at transitions.
Phosphorus and potassium should ramp from pre-flower through weeks 3–7, as Haze-heavy phenotypes continue stacking late. Avoid heavy late nitrogen, which can prolong flowering and mute terp expression. Sulfur supports terpene synthesis; ensure adequate S in bloom blends (typically 50–80 ppm range) to help preserve citrus-floral intensity.
Cultivation Guide: Training, Flowering, and Harvest
Start low-stress training (LST) early, followed by topping once or twice to create 6–12 main branches before the flip. A ScrOG approach, filling 60–70% of the screen before 12/12, helps manage the 2–3× stretch and produces uniform tops. Supercropping can tame fast risers without stunting momentum.
Indoors, expect 10–12 weeks of flowering, with some Haze-leaning phenotypes pushing to 13–14 weeks if heavily sativa. Skunk-leaning phenos may finish closer to 9–10 weeks, but the average sits around 10–12. Outdoors in temperate climates, harvest can fall from late October to early November; warmer, arid conditions are preferred to avoid late-season botrytis.
Yield potential is strong if managed properly, with experienced growers reporting 450–600 g/m² indoors under efficient LEDs. Outdoor yields per plant can exceed 500–1,000 g in large containers or in-ground beds with ample sun and season length. To determine ripeness, use trichome inspection: harvest typically near 5–15% amber heads for a balanced effect; lower amber preserves maximal “Haze lift,” while more amber tilts sedative.
Post-Harvest: Drying, Curing, and Storage
Dry in 15–18°C with 50–60% RH for 10–14 days to retain volatile monoterpenes like terpinolene and limonene. Faster, hotter dries risk flattening the citrus-floral top end and emphasizing woody or bitter notes. Gentle airflow, not directly on colas, prevents microclimates and preserves trichomes.
For curing, burp jars daily for the first week, then weekly for 3–4 weeks, keeping RH around 58–62%. Over 4–8 weeks, the bouquet integrates: citrus becomes silkier, florals round out, and skunk notes gain depth. Store long-term at stable temperatures (15–20°C) in opaque, airtight containers to slow terpene oxidation.
Phenotype Hunting and Quality Metrics
Phenos vary along a spectrum: Haze-forward plants exhibit higher terpinolene, longer finish, and more open cola structure; Skunk-forward phenos run denser with stronger base skunk and a slightly quicker finish. White Widow influence appears as heavier frost, larger trichome heads, and good hash returns. In selection, prioritize plants that balance high-top citrus/floral with a clean skunk base and maintain vigor under moderate EC.
Lab data can guide choices: look for total terpene content above 1.8% and THC in the 20%+ range for standout lots, while recognizing that entourage effects trump single-number chasing. Resin feel—gritty-sticky with visible head retention after handling—is a practical quality cue. Keep mothers from phenos that stretch predictably and fill screens evenly, as canopy uniformity improves both yield and post-harvest grading.
For extractors, watch gland head size and stalk strength in late flower; phenos that dump resin in ice water or press cleanly at 180–200°F are top candidates. Aromatically, prioritize jars that pop with fresh citrus peel and soft florals upon opening, then settle into peppered skunk as they breathe. Avoid phenos with harsh chlorophyll persistence after a proper cure, which may signal nutrient imbalance or rushed drying.
Common Pitfalls, Pests, and IPM
Long, stacked colas can be vulnerable to botrytis if humidity spikes late in flower. Maintain 45–50% RH from week 6 onward and ensure strong oscillating air across and through the canopy. Defoliate sparingly to improve airflow while preserving enough leaf for photosynthesis—target lollipop up to the first net and thin interiors.
Powdery mildew (PM) can be a concern in cool, humid rooms. Preventatively apply biologicals like Bacillus subtilis or foliar sulfur in veg (never in late flower) and keep leaf-surface VPD in the recommended range. Sticky traps and beneficial mites (e.g., Phytoseiulus persimilis for spider mites) help maintain low pest pressure.
Nutrient burn is more common than deficiency on this cross when growers chase late N; monitor runoff EC and keep late-flower N conservative. Watch for calcium-related tip burn under high light—bump Ca/Mg as needed. If aromas seem muted, reassess dry/cure conditions and confirm that sulfur and potassium were adequate in mid bloom.
Context and Evidence from the Haze and Skunk Families
Leafly’s Haze overview describes energizing, creative, and uplifted effects, while noting possible negatives like paranoia, anxiety, or dizziness in sensitive users. The terpene write-ups for the Haze family emphasize sweet citrus with compelling floral notes, matching the dominant bouquet reported for this cross. In practice, many consumers experience a euphoric, lively first hour that supports brainstorming, conversation, and movement.
Skunk family notes—exemplified by strains like Sensi Skunk and Super Skunk—underline an indica-driven calm, citrus-sweet skunky aroma, and ease of indoor cultivation. These traits align with the stabilizing role Skunk #1 plays in WW x Thai Haze x Skunk #1, shortening bloom and densifying buds without erasing the sativa head. This balance is why the cross suits gardeners seeking Haze brightness in a more cooperative plant.
Haze’s place among top strain lists and its cross-continental heritage underscore its cultural and agronomic importance. The “best of Holland and California” narrative captures how breeders like TH Seeds channeled Haze energy into reliable seeds for new generations of growers. In this cultivar, the lineage translates into a modern, data-informed sativa that respects classic flavors while meeting today’s production standards.
Consumer Tips, Dosing, and Pairings
For new users, start with 1–2 small inhalations and wait 10–15 minutes to gauge intensity. Experienced consumers often prefer micro-sessions to keep the effect productive rather than overwhelming. If you are sensitive to racing thoughts, consider blending with a CBD-rich flower—a technique sometimes called a “weed salad”—to soften the edge.
Daytime pairings include citrus-based beverages, sparkling water, or lightly sweet green tea to echo and brighten terpenes. Creative activities—journaling, sketching, playlist curation—benefit from the clear top end during the first hour. For social settings, keep water handy and rotate sessions to avoid overshooting, as high-THC citrus-herbaceous profiles can make pulses race in some individuals, a dynamic echoed in high-energy strain features.
For flavor chasers, vaporization at 175–185°C preserves terpinolene and limonene, showcasing sweet citrus and floral highs. Rolling in thin papers or using a clean glass piece prevents skunk spice from overwhelming the bouquet. Store small amounts separately for daily use to minimize terpene loss from repeated jar opening.
Closing Perspective
WW x Thai Haze x Skunk #1 stands as a thoughtful synthesis of three pillars: the crystalline intensity of White Widow, the soaring verve of Thai Haze, and the sturdy, pungent reliability of Skunk #1. It channels the classic Haze family’s sweet citrus-floral lift—well documented as energizing and creative—while trimming the excesses that make pure Hazes challenging for gardens and schedules. The profile is both nostalgic and contemporary: familiar to legacy consumers, yet tuned for modern lights, rooms, and expectations.
For growers, the roadmap is clear: manage stretch, feed steadily without overdoing nitrogen, respect VPD, and dry/cure gently to protect top notes. For consumers, it’s a daytime ally—bright, articulate, and expressive—best enjoyed with intention and paced dosing. In the lineage-rich landscape of cannabis, this TH Seeds cross earns its place as a data-informed, experience-forward cultivar that brings Holland–California heritage into sharper, sparkling focus.
