Super Silver Haze seeds are the cannabis seed genetics behind one of the most decorated sativa-dominant hybrids ever bred — a Skunk, Northern Lights and Haze cross that put Dutch seed banks on the map in the late '90s. If you're here to buy Super Silver Haze seeds, this page is the short version of what the strain is, who it suits, and how it compares to other sativa classics on the shelf. Azarius has been shipping seeds across the EU since 1999.
Buy Super Silver Haze Seeds — What You're Actually Getting
Super Silver Haze is a sativa-leaning hybrid that won the Cannabis Cup three years running (1997, 1998, 1999) — which is why it still shows up in every serious seed bank's catalogue a quarter-century later. The genetics are a three-way cross of Skunk #1, Northern Lights and Haze, bred to keep the cerebral, energetic character of Haze without the 14-week flowering times that made pure Haze a specialist-only crop.
For growers, that matters. Pure Haze is a project. Super Silver Haze brought the flowering window down to something most home growers can actually finish — roughly 9–11 weeks indoors depending on phenotype — while holding onto the long, resinous colas Haze is known for. It's one of the reasons sativa-leaning genetics became viable for indoor growers in the first place.
Super Silver Haze vs Other Sativa Classics
If you're shopping sativa-dominant seeds, the decision usually comes down to flowering time, stretch, and the character of the high. Here's how Super Silver Haze sits against the strains people cross-shop it with:
| Strain | Flowering window | Character | Good for |
|---|---|---|---|
| Super Silver Haze | 9–11 weeks | Sativa-dominant, cerebral | Growers who want Haze character without Haze flowering times |
| Amnesia Haze | 10–12 weeks | Sativa, citrus-forward | Coffeeshop-menu classic, higher stretch |
| Jack Herer | 8–10 weeks | Balanced sativa-lean | Faster finish, easier for first-time sativa growers |
| Pure Haze | 12–14+ weeks | Pure sativa, tall | Specialist growers with vertical space and patience |
How to Choose Super Silver Haze Seeds
The main decision isn't really the strain — you're already here for that. The real question is seed type. Regular seeds give you both male and female plants, which is what you want if you're planning to breed or keep mother plants. Feminised seeds are the default choice for most home growers: you plant ten, you get ten flowering females, no wasted tent space on males you'll cull anyway. Autoflowering versions of Super Silver Haze also exist — they finish faster from seed to harvest but typically yield less and express the sativa character less intensely than the photoperiod original.
If you're new to sativa-leaning genetics, be realistic about space. Super Silver Haze stretches hard in early flower — a plant that's 40cm when you flip the lights can easily double or triple. An 80x80 tent is the minimum we'd recommend; 100x100 gives you breathing room. Under a short tent with no training, you'll be tying branches down to keep colas off the light.
Frequently Asked Questions
Is Super Silver Haze hard to grow?
Not hard, but not the easiest either. The stretch and flowering time are the two things that catch new growers out — if you've only grown indica-dominant strains before, expect plants to double in height after the flip and plan your tent space accordingly.
How long does Super Silver Haze take to flower?
Roughly 9–11 weeks indoors for the photoperiod version, depending on phenotype and how you read trichomes. Outdoors in the Northern Hemisphere, harvest usually lands in late October. Autoflowering versions finish faster from seed, around 10–12 weeks total.
What's the difference between Super Silver Haze regular and feminised seeds?
Regular seeds produce both male and female plants (roughly 50/50). Feminised seeds are bred to produce only female plants, which is what you want for bud. Pick feminised unless you're specifically planning to breed or preserve genetics.
Why is Super Silver Haze still popular after 25+ years?
Three Cannabis Cup wins between 1997 and 1999 cemented its reputation, and the genetics genuinely hold up — it's one of the cleanest expressions of the Skunk/Northern Lights/Haze cross. Most modern "haze" hybrids on the market trace back to this line somewhere in their family tree.
