Autoflowering seeds
by Azarius
Amnesia Haze Auto seeds give you a mostly sativa autoflower that runs from seed to harvest in 9–11 weeks without touching a light timer. Bred from Amnesia Haze crossed with ruderalis, these genetics carry a ~70% sativa / 30% ruderalis split that delivers 16–17% THC and 2% CBD in a compact, fast-finishing plant. The effects hit with a clear, uplifting energy — the kind of uplifting sativa buzz that keeps your afternoon productive rather than pinning you to the sofa. Flavour runs earthy, spicy, and sweet, and the dried flowers snap with a crisp, resinous crackle. Grind a bud and you'll get a sharp pine-and-clove scent that sticks to your fingers long after you've packed the bowl. If you want Amnesia Haze genetics without the long veg phase and strict light scheduling, this autoflower version is the shortest route from seed to stash jar.
Amnesia Haze Auto seeds come in packs of 1, 3, 5, or 10 — pick the one that matches your space and confidence level.

Complete your setup. Growing Amnesia Haze Auto seeds indoors? The earthy, spicy terpene profile gets loud by week seven. Pair your tent with a carbon filter and inline fan combo to keep the air clean and your neighbours unbothered. For training, grab a basic LST tie-down kit — gentle bending is the safest way to open the canopy on an autoflower without stunting growth.
Light-timer fatigue is real. You set a 12/12 schedule, one power cut throws the cycle off, and suddenly your photoperiod plants are revegging or throwing hermie flowers. We've watched customers stress over light timers for years, only to switch to autos and realise they've been adding work instead of removing it. Since 1999, we've seen more lost batches from timer confusion than from bad soil.
Amnesia Haze Auto seeds solve that problem by flowering automatically based on age, not photoperiod. Set your lights to 18/6 or 20/4 on day one and leave them there until you chop. No schedule changes, no blackout curtains, no midnight alarm to check for light leaks. The plant transitions on its own timeline, typically finishing the full seed-to-harvest cycle in 9–11 weeks.
Space is the other win. At 70–100 cm tall, these plants slot into standard 100–120 cm tents and balcony corners without needing aggressive height management. You can pull 300–400 g/m² indoors or up to 500 g/plant outside — solid numbers for a fast-finishing autoflower with 16–17% THC.
Now, the honest bit: autoflowers don't handle heavy training or transplanting well. If you're used to topping, mainlining, or supercropping your photoperiods, dial it back here. Those techniques stunt autos because the plant doesn't have enough veg time to recover. Stick to low-stress training (LST) or let the plant run naturally. You'll preserve yield and avoid the frustrating mid-grow stall that catches aggressive growers off guard.
Compared to the photoperiod Amnesia Haze feminised version, the auto trades peak yield for speed and simplicity. The photoperiod cuts respond well to heavy training and can produce bigger harvests, but they demand strict 12/12 scheduling and a longer vegetative phase. If you want to harvest faster and skip the light-cycle management, Amnesia Haze Auto seeds are the smarter pick for tight timelines and smaller spaces.
Growing Amnesia Haze Auto seeds is straightforward if you follow the plant's pace instead of forcing your own.
No. Amnesia Haze Auto seeds transition to flowering automatically based on age, not light cycle. Run 18/6 or 20/4 from germination straight through to harvest for maximum yield.
Expect 70–100 cm in most setups. That fits standard 100–120 cm tents and balcony grows without heavy training or height management.
Yes. The ruderalis genetics tolerate stress better than photoperiods, skip light-cycle management entirely, and finish in 9–11 weeks — shrinking the window where things can go wrong.
Light, airy soil or coco coir with strong drainage. Autoflowers stall quickly in dense, waterlogged substrates, so avoid heavy clay-based mixes.
Aim for week 9–11, when 80–90% of trichomes turn cloudy and 10–20% show amber. Waiting longer risks overripe buds that lean sedative rather than energetic.
