Quick Answer
Super Silver Haze (SSH) and Amnesia Haze are both Terpinolene-dominant Amsterdam Haze-family sativas that won the High Times Cannabis Cup, but they produce meaningfully different experiences. SSH (Green House Seeds, NL#5 × Haze × Skunk #1, 18–23% THC) won three consecutive Cups in 1997–1999. Its Northern Lights #5 parent buffers the raw Haze intensity — producing a clean, cerebral, 2-hour daytime sativa with a more grounded terpene expression and manageable ceiling for experienced consumers. Amnesia Haze (Soma Seeds, Thai × Cambodian × Laotian × Afghani Hawaiian × Jamaican Haze, 20–22% THC) won the Cup in 2004 and again in 2012. It has almost no structural dampener — a pure multi-landrace Haze run with faster onset (2–5 min vs. SSH's 3–4 min), a longer arc (3–4 hours vs. SSH's ~2 hours), and a higher, more all-consuming cerebral ceiling. Both are Terpinolene-dominant daytime-only sativas, not appropriate for new consumers or evening use. Choose SSH if you want the Cup-winning Haze benchmark with structured intensity. Choose Amnesia Haze if you have solid SSH experience and want the maximum the Haze family offers.
Super Silver Haze and Amnesia Haze are the two most decorated sativa strains to come out of Amsterdam's cannabis culture: SSH won the High Times Cannabis Cup three consecutive years in 1997, 1998, and 1999. Amnesia Haze won the Cup Sativa category in 2004 and again in 2012 — eight years apart, a span that confirms it as a sustained standard rather than a single moment of luck. Both are Terpinolene-dominant Haze-family sativas. Both are daytime-only, experienced-consumer strains. Both appear periodically at Vermont dispensaries when cultivators work with heirloom genetics.
But they produce meaningfully different experiences, and the difference is not about THC. It is about genetic structure.
TL;DR
- SSH (NL#5 × Haze × Skunk #1): Terpinolene-dominant, variable phenotypes, 18–23% THC, 3–4 min onset, ~2 hour arc — the structured Haze with a Northern Lights buffer. Three consecutive Cup wins 1997–1999.
- Amnesia Haze (Thai × Cambodian × Laotian × Afghani Hawaiian × Jamaican Haze): Terpinolene → Limonene → Myrcene, 20–22% THC, 2–5 min onset, 3–4 hour arc — the raw multi-landrace Haze run. Cup Sativa winner 2004 and 2012.
- SSH is for experienced consumers ready to step beyond Jack Herer. Amnesia Haze is for experienced consumers who have handled SSH and want the ceiling.
The genetic structure difference
SSH's three-way cross has a built-in moderator. Northern Lights #5 is a pure indica — Afghani × Thai genetics refined by Sensi Seeds — and it serves as a structural domesticator for the wild Haze lineage. Pure Original Haze required 14–16 weeks to flower and was nearly unworkable commercially. Every subsequent Haze-family strain solved this problem by crossing Original Haze with a more manageable parent. SSH solved it with NL#5 + Skunk #1. The result is a strain that is Terpinolene-dominant, cerebral, and daytime-only — but one that has a floor beneath the Haze intensity. The NL#5 parent prevents SSH from becoming purely unmoored sativa.
Amnesia Haze's multi-landrace structure barely has this floor. The Afghani Hawaiian parent provides the only non-sativa component — approximately 20% of the strain's overall character — and it contributes physical sweetness and minor grounding, not structural dampening. The Thai, Cambodian, and Laotian sativa genetics are the foundation: Southeast Asian strains that evolved in humid equatorial climates and that produce effects tuned for sustained mental engagement, long arcs, and high intensity. These are the genetics that earned the "Amnesia" descriptor — a cerebral experience all-consuming enough to disrupt short-term memory formation at the peak.
Terpene profiles side by side
Both strains are Terpinolene-dominant, but their secondary terpene expression creates distinct experiences within that category.
Super Silver Haze shows phenotypic variability at positions two and three — a characteristic noted in its spotlight and consistent with Green House Seeds' three-way cross genetics. Different cultivators and phenotypes will express SSH differently. Caryophyllene appearing in second position produces a more grounded, slightly spicy quality — the CB2-receptor binding that contributes anti-anxiety and anti-inflammatory properties. Pinene in second produces a more focused, pine-forward clarity. In either case, Terpinolene clearly leads and the secondary terpenes ground the effect without pulling it toward sedation. The aroma reads as skunky-citrus-resinous: the Skunk #1 parent adds an earthy, pungent base note that SSH's more modern Haze descendants like Super Lemon Haze do not carry.
Amnesia Haze is more consistent: Terpinolene leads and Limonene sits in second position across most batch testing. Limonene's role here is to amplify the citrus brightness and add a sweet, tropical-fruit quality that distinguishes Amnesia Haze's aroma from SSH's more resinous-skunky profile. Myrcene sits third — a minor earthing note that keeps the experience from feeling purely citrus-bright, but not present at levels that would add body sedation. The aroma result: tropical-citrus, sweet, piney, with more fruit-forward brightness than SSH and less of the skunky resinous depth.

Effect arc: how the two experiences unfold
Super Silver Haze onset arrives at 3–4 minutes — fast by any standard, but with a quality that SSH consumers often describe as "arriving rather than hitting." The initial effect is a cerebral shift: mood elevation, sensory sharpening, increased mental energy. Over the next 20–30 minutes this builds to a sustained 2-hour ceiling that is energizing without being racy. The NL#5 presence provides just enough structural body quality to prevent the experience from becoming purely unmoored: there is a slight warmth and weight that keeps SSH in the "engaged" rather than "overwhelmed" register. The Skunk #1 parent adds potency and a resinous quality to the aroma without meaningfully shifting the sativa effect character.
The SSH experience is directional: consumers report being able to work with it — creative projects, conversations, outdoor activity. The cerebral intensity is high enough to be thoroughly engaging, low enough to allow some degree of executive function. It is not a strain where you lose the thread of what you were doing.
Amnesia Haze arrives faster — 2–5 minutes — and the quality is fundamentally different. The onset is a sharp cerebral surge rather than an arriving wave: strong mood elevation, heightened sensory awareness, mental energy, and the quality the name describes — an all-consuming present-moment experience where thoughts from a moment ago become difficult to hold. This is not distressing for experienced consumers who expect it; it is exactly what Amsterdam Cup judges selected for twice across eight years. But it is less directional than SSH: Amnesia Haze is better for open-ended creative exploration, social engagement, or sensory experience than for task completion. The extended 3–4 hour arc means that a morning session shapes a significant portion of the day.
The practical read: SSH lets you work. Amnesia Haze lets you be.
Reading the COA at a Vermont dispensary
For Super Silver Haze: Terpinolene leads clearly — this is your first check. If Terpinolene is not clearly in position one, you have a different phenotypic expression. The secondary terpenes vary by batch and cultivator. Caryophyllene in second means a more grounded, slightly spicy phenotype — this is the more settled expression of SSH. Pinene in second means a sharper pine-focused clarity. Both are legitimate SSH phenotypes. Any batch where Myrcene leads has shifted meaningfully away from the expected Haze character.
For Amnesia Haze: Terpinolene leads, and Limonene in second position is the consistent identifier — it is what produces the tropical sweetness and fruit-forward brightness that distinguishes AH from SSH on the aroma side. If you see Myrcene leading or Limonene absent from the top three, the terpene expression has shifted from the typical Amnesia Haze profile. The aroma is your real-time verification: well-grown Amnesia Haze smells tropical-citrus-sweet; SSH smells skunky-citrus-resinous. If you find a product that smells indistinguishably skunky without a tropical note and it is labeled Amnesia Haze, ask about the COA before committing.
Who should choose Super Silver Haze
- Experienced consumers ready to step beyond Jack Herer or Super Lemon Haze. SSH sits one tier above Jack Herer in ceiling intensity within the Haze family. If Jack Herer is your everyday standard and you want to understand what won the Cup three consecutive years, SSH is the logical next step.
- Consumers who want a sustained 2-hour daytime sativa without losing the ability to function. SSH's NL#5-buffered structure keeps it in the directional-enough tier — you can remain engaged in a creative project or conversation through the effect arc, which you cannot reliably do with Amnesia Haze.
- Anyone interested in cannabis genetics history. SSH won three consecutive High Times Cannabis Cups — 1997 in the Hydro category, then Overall in 1998 and 1999 — a three-year run that cemented Green House Seeds' reputation and remains one of the most decorated stretches in Amsterdam sativa history. SSH represents the peak of that genetic work and a benchmark moment in the tradition.
Who should choose Amnesia Haze
- Experienced consumers who have handled SSH comfortably and want the ceiling. The proper ordering is Jack Herer → SSH → Amnesia Haze. Each step requires more established tolerance and more confidence in your dose response. If SSH produced any anxiety or felt overwhelming, Amnesia Haze will not be more forgiving.
- Consumers planning an open-ended day. The 3–4 hour arc and the all-consuming cerebral quality make Amnesia Haze appropriate for a long creative session, an outdoor afternoon, or social time with no specific obligations afterward. It is mismatched with any commitment that requires sustained focused executive function.
- Consumers who want to understand the Southeast Asian landrace tradition. Amnesia Haze's multi-generational lineage — Thai, Cambodian, Laotian sativas filtered through decades of Amsterdam refinement — represents a genetic route that most modern hybrids do not take. Its long arc and all-consuming character are direct expressions of that heritage.
Who should skip both
- New consumers and anyone still calibrating their dose response. Both SSH and Amnesia Haze are high-THC Terpinolene-dominant sativas with fast onset and sustained duration. Neither is appropriate as a starting point. Begin with Jack Herer, establish your response there, then consider SSH.
- Anyone for whom cannabis has caused anxiety before. Terpinolene-dominant sativas at this potency and onset speed are the highest-risk category for cannabis-induced anxiety and racing thoughts. If Trainwreck, Super Lemon Haze, or Jack Herer at moderate doses produced anxiety, neither SSH nor Amnesia Haze is appropriate.
- Evening or sleep-preparation use. Both are anti-sedative by nature of their Terpinolene-dominant profile, high THC, and sativa-dominant genetics. Neither belongs in an evening routine.
Finding either strain in Vermont
Both SSH and Amnesia Haze are specialty acquisitions at Vermont dispensaries — they appear when a cultivator has specifically chosen to work with heirloom Haze-family genetics rather than the high-THC modern hybrids that dominate most menus. SSH appears more frequently than Amnesia Haze because its three-way cross genetics are more widely worked with and its flowering time is more manageable for Vermont's shorter outdoor season. Amnesia Haze, with its multi-landrace complexity, is the rarer find.
Upstate Elevator Supply Co. on Pine Street and Float On Dispensary on Church Street in Burlington carry rotating sativa selections that occasionally include Haze-heritage genetics. When either strain is in stock, ask for the COA, check the terpene panel, and trust the aroma. A cultivator who has grown SSH or Amnesia Haze well will have a product that smells distinctly of its strain; generic skunkiness without a citrus-pine or tropical note is a signal to look at the terpene panel before committing.
If neither is available, Super Lemon Haze covers the Green House Seeds Haze family with higher consistent availability, and Jack Herer is Vermont's most reliably stocked Terpinolene-dominant daytime sativa. The Haze strain family guide maps the full genetic tree if you want to understand how SSH and Amnesia Haze sit within it, and the Vermont Strain Match can recommend the closest currently available option based on your specific intent and tolerance.
