How to Grow Amnesia Haze Autoflower
Amnesia Haze Autoflower brings the legendary Amnesia Haze into a fast, easy autoflower. It is a sativa-dominant 75/25 plant with a balanced, medium 16-17% THC, an earthy, spicy and sweet flavor, and a lively, energetic and euphoric effect. Compact at around 1.2 m but a classic haze at heart, it is a great way to grow an uplifting, daytime sativa in a small footprint and a short timeframe.
This is an autoflowering strain, so it flowers on its own with age rather than on a change in the light cycle, running from seed to harvest in about 9 to 11 weeks. The seeds are feminized, so every plant grows into a flowering female and you never have to identify the sex or remove males. It keeps the long, lively flowers and haze character of Amnesia Haze, crossed with ruderalis to add the automatic flowering and quick turnaround.

Growing an Autoflowering Strain
Amnesia Haze Autoflower flowers automatically with age rather than in response to the light cycle, so it does not need a switch to 12/12 to start flowering. It begins on its own after a few weeks and runs from seed to harvest in about 9 to 11 weeks, under long days of 18 to 20 hours of light the whole way through. As a sativa-leaning haze it takes a little longer than many autos, but that extra time is what builds its long, airy flowers. Because the seeds are feminized, every plant grows into a flowering female, so there is no sexing.
Because the life cycle is fixed, the plan matters more than with a photoperiod plant: you cannot veg it longer to make it bigger, so start it in its final pot, keep any training light, and avoid stress so it uses its short life to build buds. In return you get a compact plant of around 1.2 m that still delivers a true haze, which makes it one of the easiest ways to grow a sativa in a small tent or tight space.
Climate and Where to Grow It
Amnesia Haze Autoflower suits a warm, tropical or Mediterranean-style climate with plenty of sun, steady warmth and good airflow, much like the equatorial conditions its haze ancestors came from. Because it is an autoflower, it is not tied to the seasons: it finishes on its own short timer, so you can run it all season and even fit more than one cycle into a warm year.
It performs well indoors and out. Indoors it returns a respectable 300-400 g/m² in a well-managed tent, while outdoors it can reach around 500 g per plant with full sun and room for the roots. As a compact, sativa-dominant auto of only about 1.2 m it stays small for a haze, so the main job is keeping the canopy open so light and air reach the long lower flowers.
In a tropical climate humidity is the thing to watch, so keep it under control through flowering to protect the airy haze buds: around 55-60% early on, nearer 40-45% as the flowers fill out, and lower toward harvest. The long, open flower structure of a haze actually helps with airflow, but steady humidity control still keeps the finish clean. Aim for daytime temperatures around 72-82°F (22-28°C), which this warm-climate plant enjoys.
Feeding Schedule (EC Guide)
Amnesia Haze Autoflower is a light-to-moderate feeder, and as a compact autoflower it pays to go gently: build nutrients up slowly and let the plant set the pace, since there is no long veg to recover from mistakes. Feed it through its cycle, then taper off for the final flush so the earthy, spicy and sweet flavor comes through clean and the smoke finishes smooth. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed while roots establish |
| Early growth | 0.8-1.2 | Raise nitrogen as the plant builds size |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Because it is an autoflower, Amnesia Haze Autoflower starts flowering on its own after a few weeks of growth and runs from seed to harvest in about 9 to 11 weeks, with no light-cycle change needed. As a sativa-dominant haze it takes a little longer to ripen than an indica auto, filling out with long, lively, resin-flecked flowers rather than solid, chunky colas. Thanks to that self-timed cycle you can still harvest it all season.
Yields are respectable for such a compact sativa auto: around 300-400 g/m² indoors and up to 500 g per plant outdoors with good sun and space. Give it a little gentle training so the lower flowers get light, feed it lightly through its cycle, and harvest when most of the trichomes have turned cloudy for the fullest earthy-and-spicy flavor and a lively, uplifting effect.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry is worthwhile with a haze, because a gentle dry protects the complex, spicy aroma and the trichomes that give this strain its character.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings out the earthy, spicy and sweet notes and smooths the smoke, which matters on a haze where that complex, aromatic character is the main attraction.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Amnesia Haze Autoflower is an aromatic, resin-flecked plant, so its trim works well for dry sift, bubble hash or rosin. It makes for a flavorful, spicy-and-sweet concentrate run from material most growers would otherwise throw away, keeping that signature haze character in a lighter, everyday extract.
Flavor and Terpenes
Amnesia Haze Autoflower has a classic haze flavor: an earthy, spicy character with a sweet edge, carrying the complex, aromatic profile Amnesia Haze is famous for. It is a rich, slightly peppery and sweet smoke, and a good cure really brings that haze character forward in the jar and on the inhale.
Its terpene profile shapes that character. Alpha-pinene and beta-pinene bring the fresh, earthy-pine backbone of a haze, while caryophyllene adds the warm, peppery spice behind the flavor. Myrcene lays down an earthy base, and geraniol and linalool contribute a soft, sweet-floral lift, with terpinolene rounding it out with the fresh, complex note typical of haze. Together they frame the earthy, spicy and sweet character this strain is known for.
Effects and Best Use
With its balanced, medium 16-17% THC and sativa-dominant 75/25 make-up, Amnesia Haze Autoflower delivers a lively, clear-headed experience. It is reported as energetic, euphoric and stimulating, with an uplifted, cheerful head that leans to the classic daytime sativa feel, so it works well in the morning and through the day. The medium THC keeps it approachable and easy to dose.
That energetic, euphoric and stimulating profile makes it a good daytime strain, suited to staying active, social and creative while enjoying its spicy-sweet haze flavor. The combination of a fast, compact auto grow, a true haze character and an approachable, uplifting effect is exactly why it stands out.
Common Problems and Pro Tips
The biggest thing to get right with Amnesia Haze Autoflower, as with any autoflower, is the planning: because its life cycle is fixed, you cannot veg it longer to fix a slow start. Start it in its final pot to avoid transplant stress, keep any training light, and do not let early problems linger, since the plant has little spare time to recover before it flowers. As a haze it runs a little longer, so give it those full 9 to 11 weeks.
In a warm, tropical climate the main risk is humidity, though the long, open flower structure of a haze helps airflow. Keep the air moving, hold humidity down as the buds fill out, and defoliate a few of the largest fan leaves in mid-flower so light reaches the lower flowers. Its compact size and even growth make a multi-plant run simple, since the plants grow at a similar pace.
As a pro tip, go gentle on the nutrients: autos are smaller, lighter feeders, so it is easy to overdo it with a compact plant like this, and a lighter touch keeps the spicy-sweet flavor clean. Finish with a plain-water flush and a full three to four week cure, and harvest when most trichomes are cloudy for a lively, medium-strength result.
