Blimburn Seeds is a Barcelona-founded breeder (established 2002) that built its reputation on stabilised US-classic reproductions and heavy-yielding modern hybrids. The catalogue we stock at Azarius runs from 18% CBD therapeutic strains all the way up to Fat Bastard, which Blimburn tests between 30 and 38% THC. If you're shopping for authentic genetics without paying Cookies-family boutique prices, this is the shelf to start on.
We've been selling seeds since 1999 and we'll be honest: not every breeder earns rack space. Blimburn does because the germination rates hold up, the phenotypes are consistent, and they offer the same strain in both photoperiod and auto format for a lot of their catalogue — Girl Scout Cookies, GG#4, Glookies, Cafe Racer and Fat Bastard all appear twice. That's genuinely useful if you're deciding between a quick guerrilla run and a proper indoor flower cycle.
Blimburn's range splits roughly in half between feminised photoperiod and autoflowering seeds. The table below should save you ten minutes of tab-switching.
| Format | Flowering time | Typical height | Good for |
|---|---|---|---|
| Feminised photoperiod | 8–11 weeks flower | 100–200 cm | Growers who control light cycles and want maximum yield/potency |
| Autoflower | 8–11 weeks seed to harvest | 60–100 cm | First-time growers, balcony/outdoor guerrilla, quick turnarounds |
| CBD-dominant | 8–10 weeks flower | 120–160 cm | Therapeutic users, low-THC hemp-style grows |
Blunt opinion: if this is your first seed order, buy an autoflower. Cafe Racer Auto or Girl Scout Cookies Auto finish in 10 weeks flat without you having to touch a timer. Photoperiods reward growers who already know what they're doing.
All packs ship as 3 feminised seeds. No regs, no 5/10-packs on this shelf.
Start with what you can grow, not what looks cool on Instagram. If you've got a 60x60 tent and no experience, buy a compact autoflower — Apple Fritter Auto or Purple Lemonade stay under a metre and finish fast. If you've got a proper 120x120 setup with light and ventilation sorted, the photoperiod side of the catalogue is where the real numbers live: Gelato can push 800g outdoors, Fat Bastard up to 900g.
Intermediate growers looking for a reliable workhorse should order Blue Dream, Sour Diesel or GG#4 — all forgiving, all well-documented online, all delivering what the label says. For trichome hunters and extract makers, Donny Burger, Cap Junky and Whitethorn Rose x Ooze Extraction are the ones we'd pick. When in doubt, start with Green Crack — Blimburn's version is beginner-friendly, training-responsive, and ready in 8–10 weeks.
Yes. Blimburn has been breeding since 2002 out of Barcelona and we've stocked them long enough to see consistent germination and stable phenotypes across the range. The US-classic reproductions (GSC, Sour Diesel, Blue Dream, GDP) are faithful to the original genetics, and the in-house modern hybrids test where the labels say they test.
Fat Bastard tops the range at 30–38% THC, followed by Permanent Marker (up to 34%), Cap Junky (33–34%), Blackberry Moonrocks and Blackberry Moonstones (both up to 33%). All feminised photoperiods except the Moonstones auto.
Autoflower if you're new or growing in a small space — they finish in 8–11 weeks from germination regardless of light cycle. Feminised photoperiod if you want bigger yields, higher THC, and you can control an 18/6 veg then 12/12 flower schedule. Blimburn offers both formats for GSC, GG#4, Cafe Racer, Glookies and Fat Bastard.
Every Blimburn pack we stock contains 3 feminised seeds. No single-seed packs, no 5 or 10-packs. The 3-pack format is standard across their catalogue from the US classics to the premium crosses.
Yes — CBD ACDC 1:18 is the CBD-dominant option in the range. It sits at roughly 18% CBD with 0.5–0.8% THC, bred from ACDC, NYC Diesel and Queen Mother. Feminised, 50/50 hybrid, flowers in 8–10 weeks. It's the only low-THC strain Blimburn offers through us.
Standard EU orders arrive within 2–5 working days from our Amsterdam warehouse. We've been shipping seeds since 1999 and pack discreetly as standard — no branded outer packaging, no customs flags.
