For decades, Amnesia Haze has been the queen of Amsterdam. It is the strain you buy when you want to forget your name and get lost in the canals. However, for home growers, the original photoperiod version is a nightmare: it stretches like bamboo and takes 13+ weeks to flower.
Amnesia Haze Auto is the solution to that problem.
By crossing the original Haze genetics with a vigorous Ruderalis, breeders have successfully captured the soaring, psychedelic high and the sharp citrus flavor of the original, but compressed the life cycle into a manageable 11–12 weeks. It allows growers in short-summer climates (like the UK or Northern US) to finally grow a tropical Haze outdoors. It is a tall, elegant, and powerful plant that proves autoflowers can deliver a true Sativa experience.
History and Lineage: The Haze Heritage
The lineage of Amnesia Haze is a tour of the best genetics of the 1990s.
The Original: The photoperiod Amnesia Haze (popularized by Soma Seeds) is a complex genetic soup involving Thai, Hawaiian, and Jamaican Sativas crossed with Afghani and South Asian Indicas. It won the Cannabis Cup in 2004 and 2012.
The Challenge: Haze strains are notoriously slow. They evolved near the equator and don't understand the concept of "winter."
The Transformation: Breeders spent years selecting a Ruderalis that wouldn't dilute the Sativa effects. The result is an autoflower that retains the thin leaves, the foxtailing bud structure, and the "electric" high of the Haze, but triggers flowering based on age rather than light.
Terpene Profile: Lemons and Spice
Amnesia Haze Auto has one of the most recognizable scents in the cannabis world. It is sharp, acidic, and invigorating.
Dominant Terpenes
Limonene (The Citrus): The star of the show. It provides a massive blast of lemon zest that is almost astringent.
Terpinolene (The Haze): Gives the strain its signature "Haze" smell—a mix of fresh apples, nutmeg, and turpentine.
Caryophyllene (The Spice): Adds a peppery background that tickles the nose.
Flavor Notes:
The Aroma: It smells of lemon cleaner, fresh earth, and black pepper. It is a very "bright" smell.
The Smoke: Smooth but expanding. It tastes distinctly of citrus fruits and spicy wood.
Strain Effects: The Cerebral Rocket
This is not a bedtime strain. It is widely regarded as one of the best "Wake and Bake" autos available.
The Experience
The Launch: The effects are immediate and exclusively mental. You feel a rush of energy and a desire to move or talk.
The Amnesia: True to its name, higher doses can lead to a spaced-out, dreamy state where you lose track of time or forget what you were just talking about.
The Creativity: It is excellent for artistic pursuits, music, or brainstorming. It removes mental blocks.
The Edge: Warning: For users prone to anxiety, the racing thoughts caused by this strain can be overwhelming. It is racy.
Best For: Morning energy, parties, clubbing, and creative work.
Growing Amnesia Haze Auto: The Sativa Challenge
While easier than the photoperiod version, Amnesia Haze Auto is still a "Sativa" in the garden.
Growth Structure
The Height: It is tall for an auto. Indoors, it can reach 100cm–120cm. Outdoors, it can hit 150cm (5 feet). It needs vertical space.
The Time: It is not a fast finisher. While most autos finish in 10 weeks, Amnesia Haze Auto usually requires 11 to 12 weeks. Do not chop early; the buds swell significantly in the final week.
The Feed: Like most Hazes, it is sensitive to nutrient burn. It prefers a lighter feeding schedule than heavy Indicas.
The Yield: High. Because it is a larger plant, yields of 400–500g/m² are achievable.
Grower’s Tip: Because it grows tall and thin, Low Stress Training (LST) is highly recommended. Tie down the main stem early to encourage side branches to catch up, creating an even canopy and preventing it from getting too close to your grow lights.
Final Verdict: The Sativa King
Amnesia Haze Auto is the best option for growers who love the electric, trippy effects of a Haze but don't have the time or patience for a 14-week flowering cycle. It captures the essence of the Amsterdam classic—the lemon flavor, the giggles, and the energy—in a package that is robust enough for the home garden. If you have a little extra height in your tent and can wait an extra week or two, this strain delivers a high that no pure Indica can match.
You should choose Amnesia Haze Auto if:
You love energetic, psychedelic Sativa highs.
You enjoy lemon, citrus, and haze flavors.
You live in a climate with short summers (allows you to grow Haze outdoors).
You want a high-yielding autoflower.
Score: 9.4/10 (The Coffee Shop Classic)
