Amnesia Auto by 420 Genetics

Ruderalis × Indica × Sativa

Amnesia Auto by 420 Genetics is an autoflowering hybrid developed to offer the classic Amnesia Haze experience in a more compact and faster-maturing plant. By incorporating ruderalis genetics alongside indica and sativa influences, this strain flowers based on age, allowing for quicker harvests. It is favored for its manageable size and energetic, citrus-forward profile.

Appearance & Structure

Amnesia Auto typically grows to a manageable height, generally between 60 to 110 cm indoors, with some phenotypes potentially stretching taller under intense lighting. The plant often develops a pronounced central cola with lateral branches that contribute to a conical or Christmas-tree-like structure. Its leaves may start broader but narrow during the flowering stage, displaying more sativa-like blades. Buds tend to form as tapered spears, often exhibiting foxtail-like accents characteristic of Haze genetics, and are covered in abundant, glassy resin glands.

The coloration can range from lime to medium green, with pistils that mature from golden to deep orange. Under cooler temperatures late in bloom, some plants may show subtle lavender hues on the sugar leaves, though this is not a dominant trait. The buds are generally medium to high in density for an autoflowering Haze-derived strain, providing a sticky and aromatic finish.

Aroma & Flavor

The aroma of Amnesia Auto is characterized by bright citrus notes, particularly lemon and sweet orange zest, complemented by a familiar incense-like spice. When freshly handled, flowers can release a terpinolene-forward scent with hints of pine and tropical fruit. As the buds cure, underlying notes of herbal sweetness and a subtle peppery warmth become more apparent beneath the dominant citrus profile.

On the palate, the strain offers a clean entry of lemon-lime, transitioning into flavors reminiscent of orchard fruits and a resinous, woody finish. The aftertaste often carries a characteristic dry, haze-like sensation that enhances the spicy undertones. Vaporizing at lower temperatures tends to emphasize the citrus and floral aspects, while higher temperatures bring out more pepper, wood, and anise notes.

Effects

Amnesia Auto is known for producing energetic and cerebral effects, often described as uplifting and clarity-inducing. Users may experience a heightened sense of focus and a boost in creativity, making it suitable for daytime activities or tasks requiring mental stimulation. The sativa-leaning influence contributes to a positive and alert headspace.

While primarily stimulating, the indica and ruderalis genetics contribute to a balanced experience, preventing overwhelming intensity for many users. The effects are generally considered smooth, providing a noticeable uplift without being overly sedating, aligning with the classic Haze experience in a more accessible autoflowering format.

Terpenes & Cannabinoids

While specific terpene profiles can vary, common terpenes found in Amnesia Auto include Myrcene, Limonene, Caryophyllene, Linalool, Pinene, Terpinolene, and Ocimene. These compounds contribute to the strain's distinct aroma and flavor characteristics, such as citrus, floral, earthy, and herbal notes. The interplay of these terpenes is responsible for the strain's characteristic bright and spicy scent profile.

THC levels in Amnesia Auto typically range from 15% to 25%, with many home grows yielding results in the high teens to low twenties. CBD content is generally low, usually below 1%. Minor cannabinoids like CBG may also be present in small percentages, contributing to the overall entourage effect without significantly altering the psychoactive experience.

Growing

Amnesia Auto is an autoflowering strain, meaning it flowers based on age rather than light cycles, typically starting to bloom between 3-4 weeks after germination. It is well-suited for growers seeking a faster harvest cycle, with a total seed-to-harvest time of approximately 70 to 85 days under optimal conditions. The plant's compact size makes it a good choice for smaller indoor spaces or for discrete outdoor cultivation.

This strain generally exhibits resilience due to its ruderalis genetics, making it relatively forgiving for growers. It benefits from consistent environmental conditions and can be lightly trained to optimize light penetration and canopy uniformity. Yields are considered efficient for its size, particularly when grown in optimized conditions.

Origins & Lineage

Amnesia Auto by 420 Genetics is an autoflowering hybrid derived from the celebrated Amnesia family, known for its bright Haze characteristics. The breeding process involves crossing a selected Amnesia or Amnesia-leaning hybrid with a ruderalis donor to introduce the autoflowering trait. This combination integrates sativa genetics for uplifting effects and aroma, indica genetics for structure and resin production, and ruderalis for its age-dependent flowering and resilience.

The goal of this breeding is to replicate the signature Amnesia Haze experience—characterized by its energetic, citrus-forward profile—in a shorter, more manageable autoflowering plant. This allows growers to achieve multiple harvests per season or cultivate the strain in environments where long photoperiod flowering times are not feasible.
