Amnesia Xxl Auto by Bsf Seeds
Amnesia × Ruderalis
Amnesia XXL Auto by BSF Seeds is an autoflowering cultivar that bridges modern Haze breeding with advanced, high-yielding autoflower genetics. Developed by BSF Seeds, it combines a sativa-forward Amnesia selection with a robust ruderalis donor, aiming to shorten the flowering time while maintaining the characteristic Haze profile and increasing yields. This strain is recognized for behaving like a compact sativa, offering a balance of potency and production.
Appearance
Amnesia XXL Auto typically displays a sativa-like silhouette, characterized by long, tapered colas with elongated calyx stacks. The leaves are narrow to medium-width, varying in hue from lime to forest green, and darken with increased nitrogen levels. Lateral branches contribute significantly to the overall yield, often reaching 60-80% of the main cola's height in well-lit conditions. The plant's architecture is generally symmetrical to slightly airy, promoting better air circulation and mildew prevention.
Bud density is medium to high for a Haze-dominant auto, especially when environmental factors like dry-back and Vapor Pressure Deficit (VPD) are optimized. The flower clusters are conic and spearlike, featuring a high calyx-to-leaf ratio that simplifies trimming. Dried buds commonly achieve a density of 0.45–0.65 g/cm³, balancing aesthetic appeal with resistance to mold. Resin coverage is visibly abundant, with glandular trichomes extending onto the sugar leaves.
Aroma & Flavor
The aroma profile of Amnesia XXL Auto is often described as incense-heavy and zesty, characteristic of its Haze heritage. During the later weeks of flowering, a distinct citrusy smell becomes prominent, hinting at the flavors to come. This aromatic complexity is a direct inheritance from its Amnesia lineage.
Flavors reported for Amnesia XXL Auto include notes of candy, citrus, cream, floral, grape, grapefruit, herbal, and lemon. This diverse flavor spectrum is linked to its rich terpene profile, offering a complex and enjoyable sensory experience that mirrors its aromatic qualities.
Effects
The effects of Amnesia XXL Auto are primarily cerebral, aligning with its sativa-dominant genetics. Users often report an uplifting and mentally stimulating experience, consistent with the Haze family's traditional impact.
Terpenes & Cannabinoids
While specific lab percentages are not provided, Amnesia XXL Auto is noted to have a THC content ranging from 15% to 25%, with CBD levels below 1%. The terpene profile is anchored by terpinolene, with contributions from myrcene, limonene, ocimene, and beta-caryophyllene. This combination is associated with aromas and flavors reminiscent of lemon zest, sweet herbs, and woody incense.
Growing
Amnesia XXL Auto is considered suitable for intermediate growers due to its resilience, inheriting tolerance to minor environmental fluctuations from its ruderalis parentage. It responds well to moderate defoliation and low-stress training techniques, thriving under mid-to-high PPFD lighting. The strain prefers balanced feeding and active climate control to achieve its full potential, with some sensitivity to excess nitrogen and high temperatures late in flower.
The autoflowering nature, influenced by the ruderalis genetics, typically results in a seed-to-harvest cycle of 75–95 days. Despite its auto-flowering trait, the sativa influence allows for extended vegetative-like growth, contributing to larger plant sizes, commonly reaching 80–120 cm indoors. Yields are described as high, with growers often noting dense, spear-like colas and significant lateral branching when provided with adequate space and light.
Origins and Lineage
Amnesia XXL Auto by BSF Seeds is a product of crossing a sativa-dominant Amnesia selection with a vigorous ruderalis donor. This cross was engineered to shorten the flowering period characteristic of Haze strains while enhancing yields and maintaining the desirable aromatic and flavorful qualities.
The Amnesia family itself is a significant benchmark in cannabis genetics, with Original Amnesia and its autoflowering iterations gaining popularity for their potency and production. Amnesia XXL Auto has also served as a parent strain in further breeding projects, demonstrating the stability and utility of its genetic framework for developing both high-THC and CBD-rich varieties.
