White Amnesia Haze is a sativa-dominant feminized hybrid, about 75% sativa and 25% indica, bred from White Widow and Amnesia Haze, with a floral, grape flavour. A seed listing for the same cross puts its THC at about 22%, and it is an easy grow that flowers in about 9 weeks.
History & lineage
White Amnesia Haze crosses White Widow and Amnesia Haze. White Widow was first bred in the Netherlands by Green House Seeds in the 1990s, from a Brazilian sativa and a resin-heavy South Indian indica. Amnesia Haze’s exact origins are disputed, so we don’t repeat any one version here. The cross is sativa-dominant: a listing for the same White Widow × Amnesia Haze cross rates it at 75% sativa and 25% indica, and says the Amnesia calyxes come out even whiter, denser and stickier.
White Widow, one of its parents, won the 1995 High Times Cannabis Cup (Green House’s entry), and took that year’s Bio Cup too. Amnesia Haze, its other parent, won the 2004 High Times Cannabis Cup (Barney’s Coffeeshop’s entry).
Aroma & flavour
The seed listing for the same cross gives its flavour as blossoms and grape, with a blossom and grape aroma. Leafly has no page for this cross, so its parents are the other guide: Leafly users most often report citrus, lemon and earthy flavours for Amnesia Haze, and earthy, woody and pungent ones for White Widow. Our terpene guide explains where flavours like these come from.
Effects, as users report them
Leafly has no user reports for this exact cross, so these are reports for its parent Amnesia Haze, most common first. For White Widow, users most often report happy, euphoric, uplifted and relaxed. Dry mouth and dry eyes are the most reported downsides for both, and Leafly ranks paranoia as the top negative for Amnesia Haze. The seed listing for the same cross describes a happy, social effect from the Amnesia side with a heavy body stone it calls typical of the White side. Effects vary with the person and the dose, so if you are new to cannabis, start with a small amount.
Growing White Amnesia Haze
White Amnesia Haze is a feminized photoperiod plant: it keeps growing leaves until the light drops to 12 hours a day indoors, or until the days shorten in late summer outdoors. Expect about 9 weeks of flowering indoors. Outdoors it needs a long growing season to finish its sativa-dominant flowering.
The listing for the same cross calls it easy to grow in all methods and says it produces thick, fat buds; it takes nutrients well, but go easy on feeding in the last 3 to 4 weeks. Expect around 480 g/m² (about 1.6 oz/ft²) indoors and up to 500 g (about 18 oz) per plant outdoors. Both parents are listed on Leafly as medium-height plants, so a guide height is around 100–200 cm (3.3–6.6 ft); indoor growers can keep it in check with topping or low-stress training. Judge when to harvest by the trichomes rather than the calendar.
