Super Silver Haze Cannabis Seeds by Amsterdam Genetics
Super Silver Haze seeds produce a sativa-dominant feminised cannabis plant with approximately 25% THC, a 65-70 day flowering period, and a spicy herbal aroma rooted in Haze, Skunk #1, and Northern Lights genetics. Bred by Amsterdam Genetics, these Super Silver Haze seeds deliver one of the most recognisable head highs in Dutch coffeeshop history. SSH packs dense, resinous buds that smell like a spice market wrapped in tropical fruit. If you want to buy a proper daytime strain with genuine pedigree, this is where you start.
Choose Your Pack Size
| Pack | Seeds | SKU | Best for |
|---|---|---|---|
| 3 seeds | 3 | CSAM0049 | Single-run growers or first-timers with SSH |
| 5 seeds | 5 | CSAM0050 | A full tent with room for pheno selection |
| 10 seeds | 10 | CSAM0051 | Dedicated growers who want to hunt the best phenotype |
We'd pick the 5-pack for most indoor setups. Three Super Silver Haze seeds is fine if you're confident in your germination game, but having a couple of spares means you can pick the strongest seedlings and still fill your canopy. The 10-pack makes sense if you're running multiple cycles or want to find that one standout pheno and clone her.
Super Silver Haze Genetics and Lineage
Super Silver Haze seeds carry genetics from three of the most decorated strains in cannabis history: Haze, Skunk #1, and Northern Lights. Haze provides the soaring cerebral effect and that unmistakable spicy complexity. Skunk #1 adds vigour, structure, and a shorter flowering window than pure Haze lines typically allow. Northern Lights rounds things out with resin production and a touch of physical relaxation that keeps the sativa energy from becoming jittery. Amsterdam Genetics has stabilised these genetics into a feminised seed that grows true to type — you're not rolling the dice on random phenotypes here.
According to the EMCDDA's cannabis plant monograph, sativa-dominant cultivars with Haze lineage are characterised by extended internodal spacing and elevated THC biosynthesis compared to indica-leaning varieties (EMCDDA, 2023). That genetic profile is exactly what makes SSH stand out — the Skunk #1 and Northern Lights parentage temper the typical Haze growth challenges while preserving the potency. SSH has won the High Times Cannabis Cup three years running in the late '90s, and the genetics haven't lost a step since.
Growing Super Silver Haze Seeds Indoors and Outdoors
Super Silver Haze seeds germinate reliably and produce plants that stay between 80 and 110cm indoors, flowering in 65 to 70 days — genuinely short for anything carrying this much Haze DNA. If you've ever been put off by Haze varieties that stretch to the ceiling and flower for 14 weeks, Amsterdam Genetics has bred those headaches out of this one.
She responds well to SOG and SCROG setups, and the naturally manageable height means you won't be fighting her canopy every week.
The one thing to watch: SSH likes consistent humidity during flower. She builds dense, resinous colas, and dense colas in stagnant, humid air are an invitation for mould. Keep your extraction fan running and aim for 40-50% RH once buds start fattening up. A small oscillating fan at canopy level makes a real difference.
- Germinate Super Silver Haze seeds using the paper towel method — keep towels moist, check every 4-6 hours, and expect taproots within 24-72 hours.
- Transplant into small pots (0.5L) once the taproot is 1-2cm long. Keep under 18/6 light.
- Veg for 2-4 weeks depending on your space. SSH doesn't stretch excessively, so you can veg a bit longer than you would with a pure sativa.
- Flip to 12/12 when plants reach roughly half your target final height. Expect moderate stretch in the first two weeks of flower.
- Feed with a bloom-stage nutrient schedule from week 2 of flower. SSH is a moderate feeder — she doesn't need heavy EC, but she'll show deficiencies fast if you underfeed.
- Flush for the final 7-10 days before harvest. Trichomes should be mostly cloudy with a few amber for the classic upbeat SSH effect.
- Dry in a dark room at 18-20°C and 55-60% RH for 10-14 days, then cure in glass jars for at least two weeks. The terpene profile really opens up after a proper cure.

Aroma, Flavour, and the Super Silver Haze Smoke
Super Silver Haze seeds produce buds with a spicy herbal base layered over sweet tropical fruit undertones, driven by a terpene profile rich in myrcene and caryophyllene. Crack open a cured jar and the first thing that hits you is a warm, spicy herbal funk — think crushed peppercorns mixed with dried sage. Underneath that, there's a sweetness that's hard to pin down: somewhere between ripe mango and candied citrus peel. It's complex without being confusing.
The smoke itself is thick and satisfying. On the inhale, those spicy herbal notes dominate. The exhale is where the fruit comes through — a sweet, slightly tangy finish that lingers on the palate. If you're used to modern cookie-cutter strains that all taste like cake batter, SSH is a proper wake-up call for your taste buds. The terpene profile here is old-school Dutch cannabis at its finest.
According to research published in the Beckley Foundation's cannabis science review, secondary terpenes like sabinene — commonly found in spicy-flavoured cannabis varieties — contribute to the characteristic aroma profiles of Haze-type strains and may modulate the overall experience through the entourage effect (Beckley Foundation, 2022). That spicy kick you taste isn't just flavour; it's part of the complex interplay between terpenes and cannabinoids working alongside the 25% THC.
Super Silver Haze Effects and What Users Report
Super Silver Haze seeds produce a strain known for a cerebral, energising, and uplifting effect that builds gradually over 10-15 minutes and holds steady for hours. This isn't a couch-lock strain — not even close. The head high is clear, focused, and genuinely uplifting. Creativity flows easily, conversation becomes more engaging, and mundane tasks suddenly feel a lot less tedious. It's the strain you reach for on a Saturday morning when you've got things to do but want to enjoy doing them.
According to the EMCDDA's report on cannabis potency trends in Europe, sativa-dominant varieties with THC levels above 20% are associated with more pronounced cerebral and stimulating reported effects compared to indica-dominant counterparts (EMCDDA, 2022). That tracks with what we've heard from customers over the years — SSH is consistently described as one of the best daytime options available.
One honest limitation: at 25% THC, SSH is not subtle. If you're sensitive to strong sativas or prone to racing thoughts, the cerebral intensity can be overwhelming. Starting with a small amount — around 0.4-0.5g — and waiting 15 minutes before taking more is a sensible approach for anyone trying SSH for the first time. This strain rewards patience; overconsumption can turn that clear-headed focus into anxious overstimulation.
Why Buy Super Silver Haze Seeds for Your Grow
Super Silver Haze seeds offer the full Haze experience in a plant that finishes in under 10 weeks and stays under 110cm — a combination almost no other Haze-dominant strain can match. There's a reason for that. Most Haze-dominant strains ask you to compromise — they're too tall, too slow, too fussy. SSH from Amsterdam Genetics sidesteps all of that.
Compared to something like Amnesia Haze seeds, which can easily stretch past 150cm and flower for 11-12 weeks, SSH is noticeably more forgiving. You sacrifice a tiny bit of that pure psychedelic Haze edge, but you gain predictability, manageable height, and a faster turnaround. For most home growers, that's a trade worth making. If you're after even faster results, consider autoflowering Haze varieties, though they typically sacrifice some of the potency and terpene complexity that make SSH special.
The flavour profile alone justifies growing her. In a market flooded with dessert strains and gas-terp hybrids, SSH's spicy-herbal-fruit combination stands out precisely because it doesn't follow trends. It's a classic for the same reason a good Bordeaux is a classic — the complexity rewards attention. Order a pack and see for yourself why this strain has outlasted every trend in cannabis for over two decades.
Running SSH in a tent? Pair these Super Silver Haze seeds with a complete grow kit that includes lighting, ventilation, and a carbon filter — SSH's terpene-heavy buds produce a strong aroma during late flower, and your neighbours will appreciate the filtration. For drying and curing, a set of hanging drying nets keeps your harvest organised without crushing those resinous colas. A digital hygrometer is also worth grabbing to keep humidity dialled in during the critical late-flower stage.
Super Silver Haze Strain Awards and Recognition
Super Silver Haze won the High Times Cannabis Cup in 1997, 1998, and 1999, making her one of the only strains to achieve a three-peat at the world's most recognised cannabis competition. That kind of consistency across three separate years tells you the genetics are genuinely stable and the quality isn't a one-off fluke.
Amsterdam Genetics' version carries that same genetic backbone. While every seed bank puts their own spin on classic strains, the Haze x Skunk #1 x Northern Lights foundation remains intact here. According to a 2021 study published in PMC examining marketed cannabis strains, Super Silver Haze is among the most frequently referenced strain names in both research and consumer markets, reflecting its enduring status in cannabis culture (PMC, 2021).
Frequently Asked Questions
Is Super Silver Haze a good strain for beginners to grow?
Yes, surprisingly so. Unlike many Haze varieties that demand experience, SSH stays compact at 80-110cm indoors and finishes flowering in 65-70 days. Keep humidity below 50% during late flower and she's genuinely straightforward.
What's the best time of day to use Super Silver Haze?
Morning or early afternoon. The effect is cerebral and energising — not what you want at midnight. SSH is widely regarded as one of the best daytime strains available, and we'd agree with that assessment.
How does Super Silver Haze compare to Amnesia Haze?
SSH is shorter (80-110cm vs 130-160cm), faster to flower (65-70 days vs 75-85 days), and slightly less intense on the pure cerebral edge. Amnesia Haze hits harder but demands more patience and vertical space. For most indoor growers, Super Silver Haze seeds are the more practical choice.
What terpenes are dominant in Super Silver Haze?
SSH is characterised by spicy herbal terpenes — likely including myrcene, caryophyllene, and traces of sabinene — with sweet fruity undertones. The spice-forward profile is a hallmark of classic Haze genetics and sets it apart from modern dessert-terp strains.
Can Super Silver Haze be grown in a small tent?
Absolutely. At 80-110cm indoors, SSH fits comfortably in a 60x60cm tent for 1-2 plants or an 80x80cm tent for 3-4 plants. She responds well to low-stress training and SCROG nets, which keep the canopy even and maximise light penetration.
Is 25% THC accurate for Super Silver Haze?
Amsterdam Genetics lists approximately 25% THC, which aligns with lab results from well-grown SSH phenotypes. Your actual numbers will vary with growing conditions, light intensity, and cure quality — but 20-25% is a realistic range for competent growers.
Does Super Silver Haze have any CBD content?
Negligible. SSH is bred for THC production, and CBD levels are typically below 1%. If you're after a balanced THC:CBD ratio, look at a strain specifically bred for that purpose — SSH isn't it.
Where can I buy Super Silver Haze seeds?
You can get Super Silver Haze seeds right here at Azarius in packs of 3, 5, or 10 feminised seeds from Amsterdam Genetics. We ship from Amsterdam and have carried this strain since it first became available in seed form.
