Amnesia Haze Auto is our fastest route to bring the classic Amnesia character through a complete cycle. This line is built on our Seeds66 selection of feminised Amnesia Haze and a robust Ruderalis component. The idea was simple: keep the bright, clear Haze head, but run it inside a fixed autoflower schedule from seed to harvest. It is aimed at growers who want speed and stability without giving up the recognisable Amnesia flavour profile.

Origin & Seeds66 selection
The foundation of this auto line is the same selection that drives our feminised Amnesia Haze: a clear Haze head with a citrus-driven nose, carried by a structured plant frame. On top of that sits an in-house Seeds66 Ruderalis that triggers flowering reliably without washing out the core character of the parent line.
In our own test runs we favoured phenotypes that build a stable main stem, strong lateral branches and a cycle that finishes comfortably within roughly 75 to 85 days. What mattered most was not extreme height but a readable pattern: a defined growth phase, a clear shift into flower and a ripening stage that repeats itself. Only when this behaviour showed up consistently did Amnesia Haze Auto move from trial to a fixed position in the Seeds66 catalogue.
Growth & cultivation
Amnesia Haze Auto grows compact to medium tall, with a solid branch structure and a moderate stretch. Indoors she usually finishes between 70 and 110 cm, outdoors in strong sun up to around 140 cm. From about day 25 to 30 she switches herself into flowering; there is no need to touch the light schedule. Hier zeigt die Sorte besonders deutlich, wie viel Ruhe einem Autoflower-Durchgang guttut, wenn man auf ständiges Umtopfen und hektische Eingriffe verzichtet.
In tents she performs best when started directly in the final container, typically 9 to 15 litres. Transplanting often slows autos down, so giving the roots one coherent space from the beginning helps her make the most of her timeframe. With 18 to 20 hours of light, a stable environment and balanced feeding, yields of up to 450 g/m2 are realistic. Outdoors she responds well to sites where night temperatures stay above 12 degrees and the plants get plenty of light and free airflow. The Ruderalis side helps her cope with minor fluctuations, but it does not replace a solid base in terms of substrate, watering and general room or garden hygiene.
Seeds66 tip:
Start Amnesia Haze Auto in the pot you plan to finish in and keep feeding on the gentler side during the first three weeks. Once the first flower clusters appear, you can carefully step up the schedule. A slight magnesium boost in the second half of the cycle often supports the citrus edge and helps the top buds ripen dense and even.
Aroma & terpenes
Even as an autoflower, Amnesia Haze keeps the profile that made the original line so recognisable. When you open the jar, lime and grapefruit notes sit right at the front, backed by herbal tones and a subtle floral sweetness. As the cure progresses, a light earthy nuance can appear that rounds the bouquet without making it heavy.
Limonene is the leading terpene here, supported by pinene and caryophyllene. Myrcene and smaller companions add depth in the background. In well lit rooms the overall impression stays bright and clean, very much in line with what most growers expect from a solid Amnesia expression.
Effect
The effect of Amnesia Haze Auto sets in quickly and is felt clearly in the head. Many users describe a lifted mood, more drive and a sharper sense of attention during the first phase. The Ruderalis share does not mute the Haze energy but smooths the curve, making the progression easier to follow.
With 19 to 22 % THC she clearly sits in the stronger part of the autoflower spectrum at Seeds66. In sensible doses she remains controllable and well suited to moments when you want to stay present and engaged. Pushing the dose turns the experience more intense and is best reserved for those who are used to sativa-leaning profiles.
Seeds66 approach
For Seeds66, Amnesia Haze Auto is not a cut-down stand-in for the feminised line but a complementary way to use the same direction within a tighter timeframe. We are interested in autos that can be planned with confidence, not in short cycles that happen to work once. Only lines that repeat their structure and overall behaviour over several runs earn a long term place in our range.
In practice that means: a shorter cycle is welcome, but not at the cost of character or reliability – Amnesia Haze Auto embodies exactly that balance for Seeds66.

Frequently asked questions about Amnesia Haze Auto
1. How long does a full run with Amnesia Haze Auto take?
From seedling to harvest most runs finish in roughly 75 to 85 days. The first part of the cycle is used for roots and structure, then the plant shifts visibly into flower. Watching the trichomes and giving her a few extra days at the end is often what makes the difference between a decent result and a fully developed profile.
2. How many runs per year are realistic?
Indoors, Amnesia Haze Auto fits well into a rotating schedule because the lifecycle is clearly defined. Outdoors, two runs per season can be realistic when night temperatures stay in a friendly range and the timing is chosen so that neither run drifts into the cold edges of the year. The exact number depends more on planning than on the genetics.
3. Is Amnesia Haze Auto beginner friendly?
Among Haze-leaning autos she is on the more approachable side. Growers who have the basics in place – clean water, moderate feeding, stable conditions – usually handle her well. For complete beginners it helps to read up on autoflower timing first so that key phases are not accidentally cut short.
4. What pot size works well for Amnesia Haze Auto?
Indoors, many growers are comfortable with 9 to 11 litres; in larger rooms 12 to 15 litres can also make sense. Outside, a bit more volume is often an advantage, especially in very sunny locations. The crucial point is to place her in the final pot early so that the roots can spread without interruption.
5. How noticeable is the smell during flowering?
From mid-flower onwards Amnesia Haze Auto develops a clearly noticeable scent with citrus and herbal notes. Indoors, a well matched carbon filter should be considered standard equipment, in particular in built-up areas. Outdoors the wind helps, but in sheltered spots or small courtyards the aroma can still be very present.
6. How does Amnesia Haze Auto differ from the feminised version?
The auto variant is tuned for a fixed lifecycle and straightforward handling. It delivers a very similar head character but runs without any light changes and within a shorter overall timeframe. The feminised line gives you more control over veg length and can push peak yields a bit further, but needs more time and attention in return.
