Amnesia by Hy Pro Seeds
Haze dominant × Afghan genetics
Amnesia is a sativa-leaning hybrid developed by HY-PRO Seeds, a Dutch breeder now known as Super Strains. It has been a popular choice in European dispensaries and coffeeshops for over two decades, celebrated for its distinct Haze influence, uplifting mental stimulation, and clear-headed effects.
Appearance
Amnesia plants typically exhibit a classic sativa structure with elongated, flexible branches and a tendency for upward growth. The leaves are medium to light green with slender serrations. Buds often form as long, spear-like colas, which can become quite substantial. Mature flowers are typically lime to forest green, adorned with vibrant orange pistils, and are heavily coated in trichomes, giving them a frosted appearance.
The calyxes are notably stacked, creating aerated bud clusters that are more resistant to mold than dense indica formations. While structurally sativa-dominant, Amnesia buds can finish with a surprisingly solid density, especially under stable growing conditions. The long calyxes result in a favorable flower-to-trim ratio, simplifying post-harvest processing.
Aroma & Flavor
The aroma of Amnesia is complex and zesty, characterized by prominent notes of lemon zest, sweet citrus candy, and an incense-like fragrance reminiscent of classic Haze strains. Deeper inspection may reveal secondary notes of fresh cedar, pepper, and a subtle herbal anise. When the buds are ground, these aromas intensify, releasing sharp top notes often attributed to terpinolene, alongside woody and floral undertones.
On the palate, Amnesia offers a bright and mouth-watering experience, beginning with citrus flavors that transition into spiced wood and a hint of earthiness. Vaporization tends to highlight a nuanced profile of lemon peel and pine, while combustion can accentuate peppery and incense-like notes. The aftertaste is often described as a clean, resinous haze.
Effects
Amnesia is known for delivering a strong cerebral lift, promoting a pronounced sense of mental clarity and invigorating stimulation. Users often report feeling energetic, creative, and euphoric, making it a suitable choice for daytime use when focus and uplift are desired without heavy sedation. Its effects align with those of a classic daytime sativa, providing a mood-forward experience.
Terpenes & Cannabinoids
Amnesia is characterized by a cannabinoid profile that is typically high in THC, with CBD levels consistently below 1%. This aligns with the general profile of Haze-derived sativa strains. The terpene profile is notable for contributing to its distinct sensory qualities, with compounds like terpinolene and limonene often cited for its effervescent character, while caryophyllene adds a peppery dimension.
Growing
Amnesia is considered a moderately challenging strain to cultivate, requiring attention to its sativa-dominant growth patterns. It is known for significant stretching during the initial weeks of flowering, often 150–250%. Flowering typically takes around 9-11 weeks, with some phenotypes potentially finishing a week later. Growers should be prepared for its upward momentum and potential need for trellising.
The strain performs well in both hydroponic and soil-based systems, particularly under high-intensity lighting. It is known for producing robust yields, especially when trained appropriately. Its aerated bud structure offers some resistance to mold. Maintaining stable day/night temperatures can help achieve solid bud density.
Origins & Lineage
Developed by HY-PRO Seeds, now known as Super Strains, Amnesia emerged from the Dutch breeding scene in the late 1990s and early 2000s. While its precise genetic lineage is not fully disclosed, it is widely understood to be a Haze-dominant hybrid with indica genetics, likely from Afghan landraces, selected for improved yields and a more manageable flowering period compared to pure Haze varieties. The 'Core Cut' is a particularly well-known and circulated phenotype in Europe.
