Amnesia Haze seeds are a sativa-dominant cannabis seed lineage that traces back to the original Haze crossed with Thai and Hawaiian landrace genetics — bred for an energetic, citrus-spiced high and heavy yields. Looking to buy Amnesia Haze seeds? We stock both the photoperiod and autoflower versions, so you can pick the one that fits your grow space. Azarius has been shipping seeds across the EU since 1999.
Buy Amnesia Haze Seeds — Photoperiod or Autoflower?
The short answer: pick photoperiod if you want maximum yield and don't mind managing a light timer; pick autoflower if you want a quicker, simpler grow. That's the only decision that actually matters at this stage — everything else (feeding, training, trimming) is the same job with different timing.
Amnesia Haze is one of the most-ordered sativa strains in Dutch coffeeshop culture — it's been on menus in Amsterdam for over two decades, which is why seed banks keep refining the genetics. What you're buying here isn't a novelty cross; it's a workhorse lineage that growers come back to season after season.
| Version | Grow style | Good for |
|---|---|---|
| Amnesia Haze (feminized photoperiod) | Needs a 12/12 light flip to flower | Growers who want the biggest harvest and full control over veg length |
| Amnesia Haze Auto | Flowers on its own timer, no light switch | First-time growers, small tents, anyone running perpetual harvests |
Photoperiod vs Autoflower — What Actually Changes
Photoperiod seeds give you the classic grow: veg the plant as long as you want, then flip your lights to 12 hours on, 12 hours off to trigger flowering. This is how you get monster plants. The trade-off is you need a light-tight tent and a timer that works, because any light leak during dark hours will stress the plant and cost you yield.
Autoflowers skip that step entirely. They flower based on age, not light cycle, which means you can run them under 18–20 hours of light from seed to harvest. Smaller plants, shorter total grow time, less fuss. The trade-off: you can't veg them longer to get a bigger plant, so total yield per plant is lower. For a 60x60 tent or a first grow, that's usually a feature, not a bug.
How to Choose Your Amnesia Haze Seeds
New to growing? Order the Amnesia Haze Auto. You'll harvest in about two and a half months from germination, and you won't have to think about light schedules. One pack of three is enough to learn on without committing your whole season.
Got a proper tent, a timer, and at least one grow under your belt? The feminized photoperiod is where Amnesia Haze really shines — longer veg, bigger colas, more weight at the end. Buy the 5-pack if you're running a full tent; the 10-pack if you're selecting mothers for cloning.
When in doubt, start with the auto. You can always order the photoperiod next run once you know your setup.
Frequently Asked Questions
Is Amnesia Haze a sativa or indica?
Sativa-dominant in both versions we carry. The photoperiod is a near-pure sativa from Haze, Thai, and Hawaiian lineage; the auto is mostly sativa with a small ruderalis contribution that gives it the autoflower trait. Expect an energetic, creative headspace rather than a couch-lock.
Which is easier to grow — Amnesia Haze or the autoflower version?
The autoflower, by a clear margin. It doesn't need a light-cycle flip, finishes faster, and stays shorter — all useful if your space or experience is limited. The photoperiod rewards patience and technique with bigger yields, but it's a longer commitment.
Can I grow Amnesia Haze outdoors in Europe?
Yes, both work outdoors in most of Europe. The autoflower is more forgiving at higher latitudes because it doesn't rely on shortening days to flower — you can start it in May and harvest before the autumn rain. The photoperiod needs a decent summer and finishes in October.
Are these feminized seeds?
Yes. Both Amnesia Haze and Amnesia Haze Auto are feminized, which means no male-plant guesswork and no wasted grow slots. Roughly 99% of germinated plants will come up female.
