Amnesia Haze Strain Autoflower SeedsSoma's lemon haze in a compact plant that blooms on its own
5.00 out of 5 · 2 reviewsThe Amnesia Haze strain normally needs three months of bloom and a tall room, so this autoflower version exists to cut both. Crossing the cup-winning Amsterdam haze with ruderalis genetics gives plants that flower by age, stay around 50 to 140 cm, and are listed at roughly 9 to 12 weeks from seed to harvest. The lemon, earth and spice character of the photoperiod Amnesia Haze carries through.

What is the Amnesia Haze autoflower?
Amnesia Haze Auto is the autoflowering form of Amnesia Haze, Soma Seeds' 80% sativa Amsterdam haze, crossed with ruderalis so the plants start flowering by age instead of by day length. Seed makers list roughly 9 to 12 weeks from germination to harvest and heights of about 50 to 140 cm, against the 10 to 14 weeks of bloom alone and 2 m plants of the photoperiod original. THC claims run from about 18% to 23%, and the smell stays lemony, earthy and peppery.
Barney's Farm lists its Amnesia Haze Auto as 80% sativa / 20% indica; the ruderalis share is not counted separately.
Amnesia Haze Auto finishes in about 9 to 12 weeks from seed, roughly half the total time of a photoperiod haze grow.
Amnesia Haze strain specs
The grow figures below come from seed makers that sell an autoflowering Amnesia Haze, mainly Barney's Farm and Royal Queen Seeds, plus SeedFinder. Each company uses its own ruderalis partner, so the table gives the spread; the strain history and flavor belong to Soma's photoperiod Amnesia Haze.

Where does the Amnesia Haze strain come from?
The autoflowering Amnesia Haze starts with Soma's Amnesia Haze, the Amsterdam sativa that won the 2004 High Times Cannabis Cup, crossed with a ruderalis-based auto line. Soma built the original around 2003 from haze clones and his Afghani Hawaiian; SeedFinder lists it as Afghani Hawaiian × Laos × Jamaica. Seed makers then bred that haze to ruderalis, a wild type from cold regions that flowers after a set number of weeks, and selected offspring that kept the lemony haze profile.
There is no single official Amnesia Haze Auto. Barney's Farm names its BF Super Auto #1 as the autoflowering parent, Royal Queen Seeds and others sell their own, and most companies do not publish which ruderalis line they used. That is why timing, height and THC figures for Amnesia Haze autos differ from one seed maker to the next.
How is the auto different from feminized Amnesia Haze?
The main differences are timing and size: Amnesia Haze Auto blooms on its own and is done about 9 to 12 weeks after sprouting, while the feminized photoperiod plant needs 10 to 14 weeks of 12/12 after a vegetative stage. The auto also stays far shorter, around 50 to 140 cm instead of about 2 m, and usually yields less per plant.
Figures belong to different plants. The 80% sativa ratio, cup wins and flavor notes describe Soma's photoperiod Amnesia Haze; the height, timing and yield rows describe autoflower versions.
What flavor and high does Amnesia Haze Auto have?
Aroma and flavor
Amnesia Haze Auto keeps its parent's citrus-forward profile: lemon and orange peel up front, then earthy pine, pepper and a light incense note that Barney's Farm also describes in its auto.
- Lemon
- Orange peel
- Pine
- Earth
- Pepper
- Incense
Terpenes
- Caryophyllene
- Listed first by Barney's Farm; spicy, peppery
- Myrcene
- Earthy, slightly musky undertone
- Limonene
- Sharp lemon and citrus
Amnesia Haze Auto terpene levels shift with the seed maker's ruderalis line and with growing conditions.
Reported effects
Amnesia Haze Auto is described by seed makers and growers as an uplifting, energetic and focused sativa high that arrives fast in the head. Barney's Farm notes some indica weight in the body behind it, so the effect is reported as slightly softer than the full photoperiod Amnesia Haze.
- Uplifting
- Energetic
- Focused
- Euphoric
- Talkative
Amnesia Haze Auto's commonly reported drawbacks are cottonmouth and dry eyes, and a jittery or paranoid edge for people who overdo strong sativas.
Effect notes for Amnesia Haze Auto come from breeder descriptions and grower reviews of the autoflower and its photoperiod parent. Your own experience may differ, and nothing here is medical advice.
How do you grow Amnesia Haze seeds?
Amnesia Haze autoflower seeds are grown in one straight run: sow them in their final pot, give 18 to 20 hours of light a day from start to finish, train gently in the first weeks, and expect harvest roughly 9 to 12 weeks after the seed cracks.
- GerminateDays 1–7
Sprout Amnesia Haze Auto directly in its final container, since autos lose growing days to any transplant setback.
- Early growthWeeks 2–4
Bend the main stem sideways with soft ties around week 3 to spread the narrow haze branches; skip heavy pruning.
- FlowerFrom about week 4–5
Pistils appear on their own while the lights stay at 18 to 20 hours; the plant stretches, then fills long lemony spears.
- HarvestAbout 65–85 days from seed
Check trichomes on the top cola and on lower buds; the haze side can make Amnesia Haze Auto ripen unevenly.
Grow tips for Amnesia Haze
- Pick a 10 to 15 liter pot. Amnesia Haze Auto has a fixed life span, so a roomy container from day one lets the roots fill out before bloom starts.
- Keep lights on long. Autoflowers do not need darkness to bloom; 18/6 or 20/4 gives Amnesia Haze Auto the most light hours in its short life.
- Train early or not at all. Low-stress bending in weeks 2 to 4 helps; topping later than that can stall an auto that is already switching to flower.
- Expect some haze stretch. Even as an auto, Amnesia Haze can stretch toward 1 m or more indoors, so leave space above the plant at the start of bloom.
- Use it for short seasons. Outdoors, Amnesia Haze Auto can be sown from late spring and cut in summer, well before the October rain that troubles the photoperiod haze.
- Go easy on feed. Autos usually want lighter nutrient strength than big photoperiod plants; start at about half the label dose and watch the leaf tips.
Is Amnesia Haze the right strain for you?
Great pick if you
- Want Amnesia Haze flavor without a 3-month bloom
- Grow in a small tent, a balcony or a short northern summer
- Like a bright, energetic daytime sativa
- Prefer a simple grow with no light-schedule change
Think twice if you
- Want the biggest possible Amnesia Haze harvest per plant (choose the feminized version)
- Plan to take clones or keep a mother plant, which autos do not allow
- Want a heavy, sleepy evening indica
- Like long vegetative training such as a full SCROG
Amnesia Haze strain FAQ
How long does Amnesia Haze Auto take from seed to harvest?
Amnesia Haze Auto is listed at about 9 to 12 weeks from germination to harvest. Barney's Farm gives 65 to 70 days for its version and Royal Queen Seeds gives 11 to 12 weeks, so plan for around 2.5 to 3 months in total.
Does Amnesia Haze Auto need 12/12 light?
No. Amnesia Haze Auto carries ruderalis genetics, so it begins flowering by age rather than by day length. Most growers keep the lights at 18/6 or 20/4 for the whole grow.
How tall does Amnesia Haze Auto get?
Amnesia Haze Auto usually reaches about 50 to 110 cm indoors and 100 to 140 cm outdoors, according to Royal Queen Seeds and Barney's Farm. The photoperiod Amnesia Haze can top 2 m, so the auto is a much better fit for small tents.
How much THC does Amnesia Haze Auto have?
Seed makers claim roughly 18% to 23% THC for Amnesia Haze Auto: Royal Queen Seeds lists about 18% and Barney's Farm 23%. These are breeder claims, not lab results for every pack, and CBD stays low.
Is Amnesia Haze Auto a sativa?
Amnesia Haze Auto is sativa-dominant. Barney's Farm lists its version as 80% sativa and 20% indica, matching the photoperiod Amnesia Haze, with ruderalis added only to make it autoflower.
How much does Amnesia Haze Auto yield?
Seed makers list Amnesia Haze Auto at roughly 350 to 600 g/m² indoors under strong lights. Single autos yield less than a trained photoperiod Amnesia Haze, but you can fit more plants or more runs in a year.
What is the difference between Amnesia Haze Auto and feminized Amnesia Haze?
Amnesia Haze Auto flowers on its own and finishes about 9 to 12 weeks from seed at a compact size. Feminized Amnesia Haze is a photoperiod plant that needs 10 to 14 weeks of 12/12 after veg and grows much taller, with a bigger potential harvest.
Can I grow Amnesia Haze Auto outdoors in Canada or the northern US?
Yes, Amnesia Haze Auto suits short northern summers well because it does not wait for autumn to bloom. Sown after the last frost, it is usually ready in mid to late summer, avoiding the October finish of the photoperiod Amnesia Haze. Check your local rules on home growing first.

Nathaniel Denver –
Though it was one of the simplest strains I’ve ever cultivated, this one is far superior to the others! When I harvested it, I had enormous yields! I highly suggest this product because it brings me immense comfort and enjoyment every time I use it! It smells quite strong, almost like diesel with a dash of chocolate!
Manolits –
One of the easiest strains that I’ve grown, but this is way better than the previous ones! as I harvested it, I got loads of yields! The aroma is very pungent and smells much like a diesel with hints of chocolate! It gaves me so much comfort and happiness whenever I consume it, I recommend this very much!
