Seedstockers cannabis seeds built their reputation on one thing: proper genetics at fair prices. We carry 37 Seedstockers strains at Azarius — feminised photoperiods, autoflowers, and outdoor specialists — covering everything from 30% THC monsters like Mack and Crack to mould-resistant outdoor workhorses like Zmäkdaun.

Buy Seedstockers Seeds — Complete Range Guide
Seedstockers is a Spanish seedbank that went big by going sensible — stable feminised genetics, honest specs, and prices that don't punish you for experimenting. Founded by breeders with serious Cali-collab credentials (you'll see Humboldt Seeds collaborations across half the catalogue), they've built a catalogue where almost every strain has both a photoperiod and an autoflower version. That's rare, and it's useful.
We've been stocking Seedstockers at Azarius for years because the germination rates are reliable and the phenotypes come out as advertised. When a seedbank tells you 26% THC and 9-week flowering, you want that to be true — Seedstockers delivers more often than not.
Pick Your Format — Feminised vs Auto vs Outdoor
| Format | Time from seed | Best for | Example strain |
|---|---|---|---|
| Feminised photoperiod | 11–14 weeks | Growers with a tent and timer — maximum yield control | Mack and Crack, Panty Punch |
| Autoflower | 9–12 weeks | First-time growers, perpetual harvest setups, discreet grows | Blackberry Gum Auto, Tropical Zmoothie Auto |
| Outdoor specialist | Late September harvest | Northern EU gardens, cold/wet climates | Big Yeti, Zmäkdaun |
| Superior line | Varies | Collectors chasing rare pheno hunts | Fruit Cake, Candy Dawg Auto |
If you're new, buy an autoflower. No light schedule to manage, no sexing, no guessing. Blackberry Gum Auto finishes in 9 weeks and forgives mistakes. If you know what you're doing and want the biggest, frostiest buds, order a feminised photoperiod like Mack and Crack or Panty Punch — both push 30% THC in the right hands.
What We Carry
- High-THC hitters — Mack and Crack, Panty Punch, and Rucu Cucu OG all touch 30% THC. Not for Tuesday mornings.
- Fruit and dessert profiles — Blackberry Gum, Tropical Zmoothie, Fruit Cake, Apollo Black Cherry. Candy-sweet terps, beginner-friendly growth.
- Citrus and haze — Santa Marta Haze, Mandarin Panties, Terp & Tonic. If you like sativa energy and terpenes that actually taste like the label.
- Humboldt collaborations — Thunder Banana, Blue Moby, Apollo Black Cherry. Cali genetics, Spanish stability.
- Auto versions of everything — almost every photoperiod has an autoflower twin. Same flavour, faster turnaround, smaller plant.
- Outdoor specialists — Big Yeti and Zmäkdaun were bred for growers in the north of the Netherlands, UK, Germany, Scandinavia. Mould resistance is the whole point.
- Weird and wonderful — Granny's Home smells like roasted garlic and cloves. Amaretto Tarmac smells like wet asphalt and cherries. Not everything needs to be candy.
- Workhorse yielders — BCN Critical XXL and its auto version. 8-week flowering, proper harvests, nothing fancy — just good weed.
How to Choose Your Seedstockers Seeds
Beginners: get an autoflower, buy a 3-pack, and pick something forgiving. Blackberry Gum Auto, BCN Critical XXL Auto, or Tropical Zmoothie Auto are all hard to mess up. You'll have buds in 10–11 weeks without touching your light timer.
Intermediate growers: step up to photoperiod feminised. Mack and Crack is the one we'd pick if we had a tent and wanted to show off — 30% THC, 8-week flowering, citrus-cookie terps. Panty Punch is the indica equivalent. Both come in 3-packs and 10-packs, so order the 10 if you're planning more than one run.
Advanced: go hunting. The Superior line (Fruit Cake, Sticky Fingers Auto, Candy Dawg Auto) rewards pheno hunters with exotic flavour combinations you won't find elsewhere. Terp & Tonic genuinely tastes like gin and tonic — which sounds like marketing, but it holds up.
Outdoor growers in cold, wet climates: stop fighting your weather. Big Yeti and Zmäkdaun were bred on the Dutch coast specifically for mould resistance and late-September harvests. That's the single biggest upgrade you can make if you've lost crops to botrytis.
When in doubt, start with BCN Critical XXL Auto. It's cheap, fast, and hard to kill.
Frequently Asked Questions
Are Seedstockers seeds good quality?
Yes — germination rates are consistently high and phenotypes match the spec sheets more reliably than most budget seedbanks. They work with Humboldt Seeds on a chunk of the catalogue, which means Cali genetics at Spanish prices. We've stocked them for years without significant complaints.
What's the difference between Seedstockers and Seedstockers Superior?
The Superior line is their premium tier — exclusive pheno hunts, collaborations, and rarer genetics like Fruit Cake and Candy Dawg Auto. Standard Seedstockers seeds are the workhorse catalogue (BCN Critical XXL, Panty Punch, etc.). Both are feminised and both germinate reliably.
Which Seedstockers strain has the highest THC?
Mack and Crack, Panty Punch, and Rucu Cucu OG all test around 30% THC in good conditions. Mack and Crack is the sativa-leaning option, Panty Punch is a near-pure indica, Rucu Cucu OG sits in the middle. All three are feminised photoperiods — autoflowers typically cap around 26%.
Can I grow Seedstockers seeds outdoors in Northern Europe?
Yes, but pick the right strain. Big Yeti and Zmäkdaun were bred specifically for cold, wet climates with mould-prone autumns. Most indoor-optimised Seedstockers strains will struggle with the humidity. Stick to the outdoor specialists for a proper September harvest.
Should I buy autoflower or feminised Seedstockers seeds?
Autoflower if it's your first grow or you want 2–3 harvests per year without adjusting light schedules. Feminised photoperiod if you want the biggest yields and highest THC numbers, and you've got a tent with a timer. Most Seedstockers strains come in both versions, so you can pick the format that suits your setup.
How long do Seedstockers seeds take to germinate?
Usually 24–72 hours in a damp paper towel or glass of water. Fresh Seedstockers seeds germinate at very high rates — if you're seeing poor results, check your water temperature (20–22°C is the sweet spot) and avoid rough handling of the taproot once it appears.
