25 other breeders' versions of Amnesia Haze — compare flowering times side by side →
Amnesia Haze is a legendary, sativa-dominant cannabis strain that holds a cornerstone position in Dutch coffee shop culture and global breeding history. Emerging during the mid-to-late 1990s in the Netherlands, the strain's history is deeply tied to the broader "Haze" movement, which sought to capture the intense, soaring psychoactive effects of original Haze genetics while making them viable for indoor cultivation. While the Amsterdam breeding scene was highly collaborative, Soma Seeds is widely credited with refining, stabilizing, and popularizing the definitive version of Amnesia Haze that became an international benchmark when released in 2003.
The genetics of Amnesia Haze represent an intricate and masterful blend of landrace strains from around the world. Soma’s iconic iteration is generally recognized as a cross involving Southeast Asian Sativas (such as Thai, Cambodian, and Laotian landraces) which provide the strain’s euphoric, soaring "Haze" character. This is combined with uplifting Jamaican genetics and a crucial Afghani-Hawaiian addition. The Afghani-Hawaiian influence was pivotal, as it added structural body balance, improved bud density, and significantly shortened the notoriously long flowering time of pure Haze varieties, making it far more accessible to growers.
The impact of Soma Seeds' Amnesia Haze on the cannabis industry is monumental. After dominating competition podiums—most notably winning 1st Place at the High Times Cannabis Cup in 2004 and the Sativa Cup in 2012—it quickly achieved cultural icon status. By the mid-2000s, it had become an absolute staple in Amsterdam coffee shops. Its incredible longevity in maintaining high demand for over two decades without rebranding is incredibly rare. Today, its unique citrus, earthy, and spicy terpene profile continues to serve as a vital building block for countless modern hybrids globally.

Growing Amnesia Haze: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with Amnesia or Super Skunk will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
