Appearance

This strain typically presents a slender, sativa-dominant structure, characterized by a prominent central cola and several side branches. Its leaves are narrow and serrated, and the mature flowers are elongated and moderately dense, often displaying lime to moss-green hues with tangerine to amber pistils. A notable resin coating develops by mid-flower.

The plant's structure is often described as upright and athletic, with internodal spacing that allows for decent light penetration. While it can exhibit some light foxtailing under intense conditions, a common trait from its Haze lineage, the buds are generally well-formed.

Aroma & Flavor

Amnesia Haze Automatic is recognized for its bright, zest-forward aroma, dominated by notes of lemon peel and sweet citrus. Underlying this are resinous Haze characteristics often likened to incense, with subtle herbal undertones. When broken apart, hints of pepper and pine become apparent.

The flavor profile mirrors the aroma, frequently presenting a candied lemon note upon grinding, followed by woody resinous qualities reminiscent of cedar. Some phenotypes may also exhibit subtle sweet basil or eucalyptus notes. The aroma is distinct and can be quite potent, recommending carbon filtration during cultivation.

Effects

Consumers often report that Amnesia Haze Automatic delivers a predominantly cerebral and energetic experience, characteristic of its sativa lineage. The effects are typically uplifting and uplifting, providing a clear-headed high that can stimulate creativity and focus.

This strain is known for its ability to provide a soaring mental lift without the heavy sedation sometimes associated with indica-dominant varieties. Its balanced profile makes it suitable for daytime use when an energetic boost is desired.

Terpenes & Cannabinoids

Amnesia Haze Automatic typically contains high levels of THC, reported up to 22%, with minimal CBD content (less than 1%). The terpene profile is complex, often featuring Limonene, Caryophyllene, Pinene, and Terpinolene, contributing to its distinct aroma and effects. Total terpene content in well-cultivated plants often ranges between 1.0% and 2.5%.

Growing

As an autoflower, Amnesia Haze Automatic simplifies the growing process by initiating flowering based on age rather than light cycle, allowing for 18–20 hours of light daily from seed to harvest. It typically finishes within 9–12 weeks from sprouting, with indoor yields ranging from 350–500 g/m² and outdoor yields of 60–180 g per plant.

The plant generally reaches heights of 60–120 cm indoors and 80–150 cm outdoors. It is considered relatively straightforward to grow, with a favorable calyx-to-leaf ratio that aids in trimming. Environmental factors like light intensity and nutrient levels can influence terpene expression and overall yield.

Origins & Lineage

Amnesia Haze Automatic is an autoflowering descendant of the iconic European sativa, Amnesia Haze. It was developed by crossing the original Amnesia Haze with Cannabis ruderalis genetics to impart the autoflowering trait. Nirvana Seeds is credited with popularizing this autoflower version.

The goal was to preserve the signature Haze characteristics—intense citrus aroma and cerebral effects—in a faster, day-neutral plant. This lineage results in a cultivar that reliably flowers regardless of light cycle, offering a more time-efficient cultivation experience while maintaining the classic Haze profile.
