Neville's Haze vs Super Silver Haze
Two legendary Green House Seeds sativas — one a niche psychedelic masterpiece, the other a triple Cannabis Cup champion built for the real world. Here is how they stack up.
When it comes to old-school sativa royalty, few matchups are more fascinating than Neville's Haze against Super Silver Haze. Both strains carry the same legendary NL5 x Haze genetic backbone and both originate from the same breeder — Green House Seeds. Yet they deliver remarkably different experiences in the grow room and in the pipe.
Neville's Haze is widely regarded as one of the closest things to a pure Haze expression available in seed form. Its genetics are NL5 x Haze, and it demands 14-16 weeks of flowering — a timeframe that tests even the most patient of cultivators. The reward is an intensely cerebral, almost psychedelic sativa experience that purists chase for years.
Super Silver Haze takes that same NL5 x Haze foundation and crosses it with Skunk #1, producing a sativa-dominant hybrid that finishes in just 9-10 weeks. That single addition transforms the strain from a grower's challenge into a commercial powerhouse, which helps explain why it won the High Times Cannabis Cup three consecutive years from 1997 to 1999. The Skunk influence softens the extreme sativa edge and broadens the strain's appeal without eliminating what makes Haze genetics special.
Whether you are a grower deciding which to cultivate, a consumer choosing what to seek out at a dispensary, or a cannabis historian simply curious about the relationship between two iconic varieties, this comparison breaks down everything you need to know.

Effects Comparison
Neville's Haze Effects
Neville's Haze is not a strain you reach for when you want to relax on the couch. Its pure sativa genetics produce one of the most intensely cerebral highs available, characterized by soaring euphoria, heightened sensory perception, and a psychedelic quality that experienced users describe as profound and occasionally overwhelming for newcomers.
The onset is gradual but builds with purpose. Creative thinking expands, time perception shifts, and conversations take on unusual depth. Many users report a strong sense of introspection alongside the energetic uplift. Because there is virtually no indica grounding, the experience can feel untethered — which is precisely what traditional sativa fans love about it.
Medically, Neville's Haze is valued for depression, fatigue, and mood disorders. The lack of body sedation makes it functional for daytime use despite the intensity. However, anxiety-prone individuals should approach this strain with caution due to its racey sativa profile.
Super Silver Haze Effects
Super Silver Haze delivers much of the same cerebral brightness and euphoric uplift that defines Haze genetics, but the Skunk #1 influence introduces a degree of body relaxation and emotional warmth that makes the overall experience more accessible and versatile.
The high arrives quickly with a burst of mental energy and creative motivation. Users feel talkative, focused, and socially engaged without the anxiety edge that some experience with pure sativas. The body remains light and functional throughout — ideal for daytime use, social situations, creative projects, and physical activity.
Medically, Super Silver Haze is popular for stress relief, depression, chronic fatigue, and ADHD. Its slightly higher ceiling THC of 23% combined with a more balanced profile makes it one of the most broadly recommended sativa-dominant strains for medical patients seeking daytime relief.
Terpene Profiles
Neville's Haze Terpenes
Terpinolene dominates the Neville's Haze profile, lending the strain its characteristic spicy, herbal, and faintly floral aroma that borders on incense-like. Secondary terpenes include Ocimene and Myrcene, which add soft citrus and earthy undertones without overwhelming the primary scent signature.
- Terpinolene — spicy, incense, floral, uplifting
- Ocimene — sweet, herbal, citrus
- Myrcene — earthy, mango undertone
- Caryophyllene — peppery accent, anti-inflammatory
Super Silver Haze Terpenes
Super Silver Haze shares Terpinolene as a leading terpene but integrates more prominent Myrcene from its Skunk #1 heritage. The result is a richer, more complex aroma — spicy and citrus-forward from the Haze side with a pungent, earthy sweetness underneath from the Skunk.
- Terpinolene — spicy, citrus, herbal
- Myrcene — earthy, skunky, mango warmth
- Caryophyllene — pepper, spice, stress relief
- Limonene — bright citrus, mood-elevating
Growing Comparison
Growing Neville's Haze
Growing Neville's Haze is not for the impatient or inexperienced. The 14-16 week flowering period is one of the longest found in any commercially available strain, demanding careful environmental control, strong lighting throughout the extended bloom phase, and a solid understanding of sativa stretch management.
Plants grow tall and lanky with narrow internodal spacing typical of pure sativa phenotypes. Indoor growers typically need to implement aggressive topping, LST, or SCROG techniques to manage height and improve yield distribution. Outdoor cultivation in northern climates is nearly impossible due to the late harvest window, which often falls past the first frost. Mediterranean or tropical climates are strongly preferred for outdoor grows.
Despite the challenges, the reward for patient growers is a genuinely rare and special product that commands attention from connoisseurs. Yield is moderate, typically in the range of 400-500g per square meter indoors under optimal conditions.
Growing Super Silver Haze
Super Silver Haze is the far more practical choice for home growers and commercial cultivators alike. The 9-10 week flowering time is a massive operational advantage — you can run nearly two full cycles of Super Silver Haze for every one cycle of Neville's Haze.
The Skunk #1 genetics contribute disease resistance, improved resilience to environmental fluctuation, and slightly more compact growth structure compared to Neville's Haze, though plants still exhibit significant sativa stretch and benefit from training. Indoor yields are generous, typically ranging from 500-600g per square meter under strong lighting.
Super Silver Haze is also more suitable for outdoor cultivation in a broader range of climates, finishing before the autumn cold sets in across most temperate regions. It remains a moderately challenging strain — not ideal for absolute beginners — but experienced home growers will find it manageable and highly rewarding.
Which Should You Choose?
The choice between Neville's Haze and Super Silver Haze really comes down to what you prioritize — purity or practicality, intensity or accessibility.
Choose Neville's Haze If...
- You are a true sativa connoisseur who wants the most authentic Haze expression possible
- You have the patience and skill to manage a 14-16 week flowering plant
- You are seeking a deeply psychedelic, cerebral high without any indica grounding
- You grow in a warm climate with a long outdoor season
- Rarity and genetic purity matter more to you than convenience
Choose Super Silver Haze If...
- You want the Haze experience in a more practical, faster-finishing package
- You prefer a more balanced high that is easier to enjoy across a wider range of activities
- You are growing indoors or in a temperate climate with a shorter season
- You want a proven, award-winning strain with consistent performance and wide appeal
- You are newer to sativa cultivation and want something more forgiving than a pure Haze
For most growers and consumers, Super Silver Haze is the more sensible everyday choice — and its three consecutive Cannabis Cup wins speak to how successfully it delivers on its promise. But for those willing to invest the extra weeks and effort, Neville's Haze offers an experience that few strains can match.
