Amsterdam Amnesia Feminized Seeds – Dutch Passion’s Original Haze with XXL Yields & 20%+ THC

Amsterdam Amnesia by Dutch Passion is the definitive feminized Haze strain—delivering sky-high THC, a mind-bending sativa high, and XXL yields of dense, resin-coated buds in just 9–11 weeks of flowering.

Struggling with weak, airy sativas that take forever to finish and barely pack a punch? You’re not alone. Most Haze varieties stretch endlessly, flower for 14+ weeks, and leave you with fluffy buds that vanish in your fingers. It’s frustrating when you invest months only to get low potency, poor structure, and a harvest that smells like hay—not the legendary citrus-pine explosion you were promised.

That’s where Amsterdam Amnesia changes everything. Bred from the original Amnesia Haze genetics that defined Amsterdam’s coffee shop scene, this strain gives you the authentic, trippy Haze experience—but with compact buds, faster flowering, and yields that’ll shock even seasoned growers. No more waiting forever or settling for mediocre smoke.

Why Amsterdam Amnesia outperforms typical Haze strains

Unlike traditional Hazes that demand endless patience and expert-level care, Amsterdam Amnesia is surprisingly forgiving. It matures in just 9–11 weeks—weeks faster than classic Hazes—while producing buds that are noticeably denser and heavier. Its sativa structure allows light penetration, but its robust branches support serious weight without snapping. Plus, it’s naturally resistant to spider mites, so your grow stays clean even in shared spaces.

Key features you’ll notice from the very first grow

• XXL yields: 500–600 g/m² (1.64–1.97 oz/ft²) indoors or up to 1.5 kg (3.31 lb) per plant outdoors.
• Fast-flowering Haze: Ready in 9–11 weeks—ideal if you hate waiting 14+ weeks for sativa harvests.
• Compact sativa buds: Long, resinous colas that are far denser than typical airy Haze flowers.
• High THC: Averages 20%, with lab tests showing peaks near 25%—delivering a powerful, long-lasting head high.
• Classic terpene profile: Dominated by limonene, beta-caryophyllene, and pinene for that unmistakable citrus-pine-haze punch.
• Beginner-friendly: Stable genetics make it easy to grow for all skill levels—no Haze headaches here.

Who this strain is especially interesting for

Amsterdam Amnesia is your go-to if you crave the legendary Haze experience but want real-world practicality—faster harvests, heavier yields, and connoisseur-grade flavor without the drama.

• Growers who love energetic, cerebral highs but hate waiting months for sativa harvests.
• Connoisseurs chasing authentic Amnesia Haze flavor—citrus, spice, and that gasoline-like aftertaste.
• Indoor cultivators using SCROG or SOG who need a sativa that fills the canopy without collapsing.
• Outdoor growers in Mediterranean or tropical climates seeking massive, mold-resistant plants.

How to integrate it into your grow routine without overcomplicating things

Start seeds in a light, airy mix like Light Mix BioBizz 50L to encourage early root development. During veg, use 18/6 lighting and apply gentle LST or SCROG—this strain responds beautifully to training. In flower, keep nutrients moderate (Haze strains prefer slightly less feed) and maintain RH below 50% to protect those dense buds. For explosive resin production, consider Frooting Power BAC in mid-flower. Flush for 10 days before harvest, then dry slowly at 18–22°C (64–72°F) and 55% RH for maximum terpene preservation.

Frequently Asked Questions

Is Amsterdam Amnesia suitable for beginners?

Absolutely. Despite being a sativa, its stable genetics and forgiving nature make it one of the easiest Haze strains to grow. Just avoid overfeeding and give it room to stretch.

Can I grow it outdoors in Europe?

Only in warm, dry regions like southern Spain, Italy, or Greece. It needs a long, sunny summer and won’t finish in time in cooler climates.

How does it compare to regular Amnesia Haze?

Amsterdam Amnesia is a refined version—same legendary flavor and high, but with faster flowering (9–11 vs. 12–14 weeks) and denser, higher-yielding buds.

Does it need a lot of nutrients?

No. Haze strains are sensitive to overfeeding. Start low and increase gradually. Yellowing leaves early on often mean it needs more nitrogen—not less.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of Haze strains over the years, and most left me disappointed—too slow, too airy, too finicky. Amsterdam Amnesia changed that. I ran it in a SCROG tent with 9 weeks of veg under LED, and the canopy filled out perfectly. The buds were shockingly dense for a sativa, dripping in trichomes, and the smell during late flower was intoxicating—like fresh lemons and pine needles with that classic Haze kick. I harvested over 550 g/m², and the smoke? Pure nostalgia with a modern punch. It’s now my benchmark for any sativa. If you’ve been burned by weak Hazes before, this is your redemption strain. I’d recommend it to anyone who wants the real Amsterdam experience without the wait.
