Amnesia Haze by Barney's Farm

Amnesia Haze is one of the most famous sativas ever to come out of the Amsterdam coffeeshop scene, and Barney’s Farm’s feminized version keeps that reputation alive. This 80% Sativa / 20% Indica strain blends Jamaican, Thai, South Asian and Cambodian landraces into a plant with 24% THC and a classic Haze personality.

The buds grow long and airy in true sativa style, with a high flower-to-leaf ratio, lime-green calyxes, fiery orange pistils and a dense crust of resin. They look as electric as they smoke.

Indoors, plants reach up to 140 cm (55 in) and yield up to 650 g/m² (2.13 oz/ft²). Outdoors in a warm climate, they can top 200 cm (79 in) and produce up to 1000 g/plant (35.3 oz/plant).

Lineage: Landrace Haze from Four Regions

The roots of Amnesia Haze run through some of the most respected sativa landraces on the planet. Jamaican genetics bring sweetness and vigor, Thai lines contribute incense, spice and a soaring high, while South Asian and Cambodian influences deepen the earthy, exotic character of the smoke.

Barney’s Farm refined this mix over years of selection into a stable feminized line that has earned a cup-winning reputation. The 20% indica share is small, but it helps the plant finish in a realistic indoor window and keeps the buds firmer than a pure equatorial Haze.

Aroma, Flavor and Effect

The aroma is classic Haze: pungent, spicy and laced with fresh citrus. Bright lemon notes leap out first, followed by earthy undertones and a soft sweetness that drifts through the room once the buds are broken up.

Barney’s Farm lists the taste as citrus, haze, earthy and spicy. Lemon zest leads the inhale, the familiar incense-like Haze flavor fills the middle, and a peppery spice lingers on the exhale. It is a profile that has been carefully kept intact over generations of breeding.

The effect is energetic, stimulating, cerebral and euphoric. The rush hits fast, ideas start flowing and colors and music feel sharper. The headspace can become so absorbing that time seems to slip, which is the effect behind the name. Despite the intensity, the high stays upbeat rather than edgy, which makes it a favorite for creative daytime sessions.

Growing Amnesia Haze Indoors and Outdoors

Amnesia Haze stretches hard during the first weeks of flowering, so plan the vertical space before the flip. Indoor plants finish at roughly 100–140 cm (39–55 in), with flowering taking 70–85 days after the switch to 12/12. Topping in veg, followed by a SCROG net, is the classic way to keep the canopy flat and fill the screen with dozens of tops.

The long flowering time is the price for that Haze quality, and it pays off in heavy, resin-soaked spears. Keep the light schedule steady and nutrients moderate, since sativas like this one rarely need heavy feeding.

Outdoors, the plant loves a warm, sunny climate, where it can grow beyond 200 cm (79 in) and produce up to 1000 g (35.3 oz). Harvest comes late, in the third to fourth week of October in the Northern Hemisphere, so it fits regions with long, mild fall weather or a greenhouse setup.
