Amnesia Dream XL

Amnesia Dream XL Auto Cannabis Seeds by Kannabia

Amnesia Dream XL Auto is an autoflowering feminised cannabis seed from Kannabia that delivers the classic Amnesia Haze experience in as little as 10 weeks from sprout to harvest. Bred from Soma's original Amnesia Haze crossed with Amnesia Auto, this sativa-dominant auto packs up to 18% THC, citrus-earth terpenes, and yields that punch well above her autoflower weight class. If you've ever wished you could grow proper Amsterdam coffeeshop Amnesia without the 12-week photoperiod headache, this is your seed.

Why Amnesia Dream XL Auto Seeds Deserve a Spot in Your Grow

Amnesia Haze is one of those strains that never left the Amsterdam menu boards — and for good reason. That citric, earthy, slightly floral nose followed by a potent, cerebral, long-lasting effect is hard to replicate. The problem? Traditional Amnesia Haze photoperiods are notoriously slow growers with flowering times that can stretch past 12 weeks, and they tend to shoot up like beanpoles indoors. Not exactly beginner-friendly.

Kannabia's Amnesia Dream XL Auto solves most of those headaches. The ruderalis genetics shave weeks off the total cycle — we're talking 10 weeks from germination to trimming, though some phenotypes may need closer to 90 days to fully mature. She stays manageable indoors yet can stretch up to 200 cm outdoors if you give her room and sunshine. The autoflowering trait means no light schedule changes, no sexing worries (she's feminised), and no fussing about light leaks during flower. You plant, you feed, you harvest.

The one honest limitation: at up to 18% THC, she sits slightly below some of the heavier-hitting photoperiod Amnesia cuts that can push past 22%. But for an autoflower that finishes this fast, 18% with a proper terpene profile is genuinely impressive. You're trading a few percentage points for weeks of saved time and a far easier grow — and most growers we've spoken to consider that a fair deal.

Amnesia Dream XL Auto Genetics and Lineage

Amnesia Dream XL Auto traces her roots directly to Soma's original Amnesia Haze — the same cut that put Amsterdam coffeeshops on the map in the early 2000s. Kannabia crossed that legendary sativa with their own Amnesia Auto to create a seed that keeps the Dutch heritage intact while adding autoflowering convenience. The result is a sativa-dominant hybrid with a touch of indica and Cannabis ruderalis in the background. You get the vigour and cerebral character of Amnesia Haze, slightly tamed by the indica influence for a more compact structure and a faster finish.

Aroma, Flavour, and Flower Structure of Amnesia Dream XL Auto

True to her Amnesia lineage, this auto produces long, dense sativa-shaped flowers with beautiful shades of green, golden hues, and bright orange highlights from her long pistils. The resin coverage is generous — expect a proper frost of trichomes that makes the buds sticky to the touch and a pleasure to trim (or a nightmare, depending on how you feel about resin-caked scissors).

Crack open a cured bud and you'll get that unmistakable Amnesia nose: sharp citrus up front — think lemon zest and grapefruit peel — layered over an earthy, almost woody base with subtle floral notes weaving through. It's the kind of aroma that fills a room when you open the jar. The flavour follows suit: tangy citrus on the inhale, smooth earthy tones on the exhale, with a floral sweetness that lingers. If you've smoked Amnesia in an Amsterdam coffeeshop, you'll recognise it immediately.

How to Grow Amnesia Dream XL Auto Seeds

1. Germinate your Amnesia Dream XL Auto seeds using the paper towel method or directly in a small pot of moist, light seedling mix. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their final container early — autoflowers don't love being repotted mid-grow. A 15–20 litre fabric pot with well-aerated soil (or coco/perlite mix) works well. Indoors, run your lights on an 18/6 or 20/4 schedule from start to finish.
3. During the vegetative phase (roughly weeks 1–4), keep feeding light. She's vigorous but doesn't need heavy nutrients early on. Low-stress training (LST) in weeks 2–3 helps open up the canopy and maximise light penetration — she responds well to being tied down.
4. Flowering kicks in automatically around weeks 4–5. Switch to bloom nutrients and watch the stretch. Indoors, she stays compact enough for a standard grow tent. Outdoors, give her full sun and she can push towards 200 cm.
5. Monitor trichomes from week 8 onwards. Most plants finish around week 10, but some phenotypes benefit from an extra week or two. Harvest when trichomes are mostly milky with a few turning amber for the classic cerebral Amnesia effect.
6. Dry in a dark, ventilated space at 18–21°C and 55–60% humidity for 7–10 days. Cure in glass jars for at least 2 weeks — the citrus terpenes really develop during the cure.

Indoor vs Outdoor: What to Expect from Amnesia Dream XL Auto

Indoors, Amnesia Dream XL Auto is one of the better-yielding autos we've come across — 400 g/m² is a strong number for any autoflower, let alone one that finishes in 10 weeks. Keep your canopy even with some gentle LST and you'll make the most of your light footprint. Outdoors, she's a different beast: given space and sunshine, she'll stretch towards 200 cm and reward you with 200–300 grams per plant. The autoflowering genetics mean you can plant successive rounds throughout the growing season for multiple harvests.
