¶ Neville's Haze
¶ Overview
Neville's Haze is a pure sativa created by Mr. Nice Seeds (co-founded by Neville Schoenmaker, widely regarded as the father of modern cannabis breeding) from a cross of original Haze genetics with Northern Lights #5. The strain is named in honor of Neville Schoenmaker himself and represents one of the most authentic and intensely cerebral Haze varieties ever stabilized. Neville's Haze delivers THC levels in the 18-23% range with a terpene profile dominated by terpinolene, caryophyllene, and pinene, producing a sweet, earthy, and spicy aroma. The strain is renowned for its extremely cerebral and almost psychedelic effects, making it one of the most potent and long-lasting sativas available. However, its 70-90+ day flowering time makes it one of the most challenging sativas to cultivate, demanding significant patience from growers.

¶ Genetics & Lineage
Neville's Haze combines two landmark genetics:
- Original Haze -- The classic sativa genetics originating from the 1960s California scene, believed to include Colombian, Mexican, Thai, and South Indian landrace genetics. Original Haze is the foundation of modern sativa breeding.
- Northern Lights #5 -- A specific Northern Lights phenotype selected for its Afghani indica structure and reliable genetics
Parent lineage: Original Haze x Northern Lights #5
Neville Schoenmaker's breeding work at Mr. Nice Seeds was focused on preserving and enhancing the original Haze genetics while introducing just enough Northern Lights #5 structure to make the strain cultivable. The result is a pure sativa that captures the cerebral intensity of original Haze varieties while being slightly more manageable than unrefined landrace Haze. The Northern Lights #5 contribution is minimal, serving primarily to stabilize the genetics rather than alter the sativa-dominant effect profile.
¶ Cannabinoid Profile
| Cannabinoid | Typical Range |
|---|---|
| THC (Total) | 18-23% |
| CBD | <1% (typically 0.1-0.3%) |
| CBG | 0.5-1.5% |
| CBN | <0.5% (increases with age) |
Neville's Haze sits in the high THC range, providing pronounced potency with the extremely cerebral, long-lasting character that defines original Haze genetics.
¶ Terpene Profile
| Terpene | Approximate Share | Notes |
|---|---|---|
| Terpinolene | 25-40% | Primary terpene; floral, herbal, citrus notes defining the cerebral, almost psychedelic quality |
| Caryophyllene | 15-25% | Significant presence; spicy, peppery, earthy character |
| Pinene | 10-15% | Pine freshness adding clarity and complexity |
| Myrcene | 5-10% | Lower, consistent with the clear-headed pure sativa profile |
| Humulene | 3-7% | Earthy, hoppy depth |
The terpinolene-caryophyllene-pinene combination produces the sweet, earthy, and spicy aroma that defines Neville's Haze.
¶ Effects & Experience
Neville's Haze is widely reported to produce:
- Extremely cerebral effects -- A pronounced, long-lasting head high that is among the most intense of any sativa strain
- Psychedelic and expansive qualities -- Users frequently report a dreamy, almost psychedelic quality that is rare among modern cultivars
- Energy and mental stimulation -- Strong, sustained mental energy that can last for hours
- Creative and philosophical thinking -- Enhanced creative flow and reflective, philosophical thought patterns
Onset: Effects begin within minutes when smoked or vaporized; 30-90 minutes when consumed orally.
Duration: 2-4 hours for inhaled consumption; 4-8 hours for oral consumption. The cerebral effects are notably long-lasting even among sativa strains.
Intensity: Strong. Neville's Haze delivers potent, long-lasting effects that are best suited to experienced sativa users.
⚠️ Effects are self-reported and vary by individual, dose, tolerance, and consumption method. Not a prediction of any individual's experience. The intensely cerebral nature of Neville's Haze may be overwhelming for users sensitive to sativa effects.
¶ Aroma & Flavor
- Smell: Sweet, earthy, and spicy with herbal and pine undertones. The terpinolene dominance gives it a floral, almost perfumed quality that is distinctive of original Haze genetics, with the caryophyllene adding a spicy, peppery edge.
- Taste: Sweet and earthy on the inhale, with spicy and pine notes on the exhale. The flavor is classic Haze -- clean, herbal, and complex, appealing to users who appreciate traditional sativa taste profiles.
¶ Medical Usesdanger
Not Medical Advice -- The following lists commonly reported therapeutic applications. This does not constitute medical advice. Consult a healthcare professional before using cannabis therapeutically.
Commonly reported uses include:
- Depression and low mood -- The intensely uplifting, cerebral effect is frequently cited for significant mood elevation
- Fatigue -- The sustained mental energy provides strong, long-lasting daytime functionality
- Stress relief -- The cerebral euphoria is reported to reduce mental stress for extended periods
- Creative blocks -- The creative and philosophical stimulation is valued by artists and thinkers
- ADHD and focus difficulties -- Some users report improved concentration from the sustained mental energy
¶ Adverse Effects
Commonly reported adverse effects:
- Dry mouth
- Dry eyes
- Anxiety or racing thoughts at higher doses
- Increased heart rate
- Paranoia, particularly in users sensitive to intensely cerebral sativa effects
- Difficulty sleeping if used late in the day
- The psychedelic quality may be disorienting for some users
- The very long flowering time means limited harvests for indoor growers
¶ Growing Information
| Attribute | Details |
|---|---|
| Difficulty | Challenging -- the extremely long flowering time and pure sativa structure require significant experience and patience |
| Flowering Time | 70-90+ days (indoor) -- one of the longest flowering times of any stabilized cultivar |
| Yield | 300-400 g/m² indoor; 400+ g/plant outdoor |
| Plant Height | Tall to very tall -- significant sativa stretch; extensive height management required indoors. May require 12/12 light cycle earlier than other strains to control height. |
| Preferred Environment | Indoor or outdoor; prefers warm, dry conditions with excellent air circulation. Outdoor growing in warm climates with long growing seasons produces the best results. |
| Resistance | Moderate resistance to mold and pests. The pure sativa genetics are naturally resilient but the long flowering period requires consistent environmental management. Responds well to SCROG and aggressive topping. |
Neville's Haze is one of the most challenging sativas to grow. The extremely long flowering time (70-90+ days) demands exceptional patience and consistent environmental management over an extended period. The pure sativa structure requires significant height management, and indoor growers must plan for substantial vertical space. The strain performs best outdoors in warm climates with long growing seasons that can accommodate the extended flowering period. Outdoor harvest in the Northern Hemisphere typically falls in late October to November. For indoor growers, the long flowering time means fewer harvests per year, but the authentic Haze experience makes it worthwhile for dedicated sativa enthusiasts.
