Super Sativa Seed Club cannabis seeds are the real deal from one of Amsterdam's most storied breeders — a collective that first put pure Haze genetics on the map in the late 1980s and quietly returned with a catalogue of preserved sativas, modern hybrids and autoflowers. Buy SSSC seeds from Azarius and you're ordering straight from the source of strains like Kees' Old School Haze, Karel's Haze and Prima Holandica. Online smartshop since 1999.
Super Sativa Seed Club Seeds — Buying Guide
Super Sativa Seed Club (SSSC) is an Amsterdam breeder collective that preserves original 1980s Haze bloodlines and crosses them with modern Cali genetics. If you care about where Dutch sativa actually came from, this is the shelf to shop. We currently carry 14 SSSC strains at Azarius — a mix of pure sativas, sativa-dominant hybrids, indica crosses, a Lebanese hash plant and one autoflower.
The catalogue splits cleanly into three camps. The purists want Kees' Old School Haze or Prima Holandica — 100% sativa, 12–13 weeks flowering, massive plants, zero compromise. The grower who wants Haze character without the marathon flower goes for Karel's Haze (8–9 weeks) or Kosher Haze (8 weeks, under 120cm). And the flavour hunters pick Creamy Kees (vanilla-to-lemon shift), Strawberry Cookies (6–7 weeks) or Bruce Lemon Diesel.

Who SSSC Is, and Why It Matters
The original Super Sativa Seed Club was one of the first Dutch seed collectives, founded in the late 1980s when Amsterdam coffeeshop menus were dominated by Haze varieties most growers today have never actually tasted. The current SSSC is a continuation project — growers and breeders working from preserved mother plants and original bloodlines to bring those genetics back in stable, modern seed form. That's why the catalogue keeps coming back to names like Karel (the breeder) and Kees (the Haze line).
Our honest take: if you're new to growing, SSSC is not the easiest place to start. The pure sativas will stretch 3–4x in flower and want 12+ weeks of bloom. That's a commitment. Get the basics down on something forgiving first, then come back for the Haze.
How to Choose Your SSSC Seeds
First-time growers: order Auto Creeper or Purple OG Punch. Auto Creeper finishes in 11 weeks from seed, stays under a metre, and gives you sativa-style buds without the scheduling headache. Purple OG Punch is feminised, indica-heavy, 7–8 weeks of flower, and handles cold better than most.
Intermediate growers: Karel's Haze is the sweet spot. Real Haze character, 8–9 weeks flower, manageable indoor height. Kosher Haze is the indica-leaning version if you want it shorter still. Creamy Kees if flavour matters more to you than yield.
Experienced growers: this is where SSSC earns its reputation. Kees' Old School Haze and Prima Holandica are regular seeds, pure sativa, and reward patience with yields and effects that feminised moderns rarely match. Karel's Herer Haze belongs outdoors in a long season. Frosty Friday if you're making hash.
When in doubt, get Karel's Haze. It's the strain that best represents what SSSC does — old-school DNA, modern finishing time, heavy resin, proper flavour.

Frequently Asked Questions
What is Super Sativa Seed Club known for?
SSSC is known for preserving original 1980s Dutch Haze genetics — specifically the pure sativa lines that built Amsterdam's coffeeshop reputation. Strains like Kees' Old School Haze and Karel's Haze trace back to breeding stock most seed banks no longer have access to.
Are SSSC seeds good for beginners?
Some are, most aren't. The feminised hybrids (Purple OG Punch, Lemon OG, Strawberry Cookies) and Auto Creeper are beginner-friendly. The pure sativas — Prima Holandica, Kees' Old School Haze — stretch aggressively and need 12+ weeks of flower, so skip those for your first grow.
What's the difference between regular and feminised SSSC seeds?
Regular seeds produce roughly 50/50 male and female plants — you'll need to identify and remove the males. They're what breeders and cloners want. Feminised seeds produce only female (bud-producing) plants and are easier for home growers. SSSC offers both, depending on the strain.
Which SSSC strain has the shortest flowering time?
Strawberry Cookies at 6–7 weeks is the fastest in bloom. Purple OG Punch finishes in 7–8 weeks. For autoflower, Auto Creeper goes from seed to harvest in 11 weeks total.
Can I grow SSSC sativas indoors?
Yes, but pick carefully. Karel's Haze, Kosher Haze and the feminised hybrids are indoor-friendly. The pure sativas (Prima Holandica, Kees' Old School Haze, Karel's Herer Haze) will push the ceiling of a standard tent — plan for aggressive training or pick a strain that wasn't bred to reach for the sun.
