Amnesia Haze Feminized by Royal Queen Seeds is the undisputed king of Amsterdam coffeeshop sativas. This genetics combines overwhelming vegetative vigor with a flowering phase that requires agronomic precision. It develops very long floral lances and demands strict control over vertical space. It is a challenging but generous plant, capable of rewarding the grower’s patience with buds saturated in silvery resin of high psychotropic impact.

Amnesia Haze Feminized in brief

This variety requires 10-12 weeks of flowering to complete its development. It offers a massive indoor yield, estimated between 500 and 600g/m² under optimal conditions. THC levels steadily stand between 20% and 22%. Post-switch vertical elongation is extreme. The terpene profile is dominated by strong notes of chemical lemon, pine, and incense. It adapts very well to greenhouse cultivation and outdoors in Mediterranean climates.

Intro and History

The genetic roots of this commercial pillar are described in the Seedfinder records, tracing a complex cross between Asian bud landraces and Jamaican sativas. RQS stabilized this line to offer commercial stability to a classic known for its exuberance. A genetic that extends biological times to maximize the chemical complexity of the inflorescence.

Cultural Management (Indoor and Outdoor)

Indoors, containment is mandatory. Vertical elongation can triple the plant’s size, making a net (SCROG) necessary to level the apical zone. Nutrient absorption requires a controlled EC of 1.5-1.7 in full bloom; nitrogen must be drastically reduced as early as the third week. Outdoors or in guerrilla setups, as highlighted by diaries on GrowDiaries, it requires long, dry autumns. Its extensive root platform prefers large final pots to sustain the wide branch volume, which will require solid mechanical supports in October.

Terpene Profile and Effect

The bouquet of Amnesia Haze is a citrus assault. It releases a pungent smell of fresh cedar, sour lemon, and solvent, followed by a deep background of incense and spicy earth. The mental impact is overwhelming: it triggers a wave of psychedelic euphoria and creative stimulation, perceived by users as ideal for daytime hours. Physical relaxation is minimal, leaving the mind active and talkative for hours.

Amnesia Haze vs Other Queens

Amnesia Haze vs Super Silver Haze

While Super Silver Haze retains darker, woodier, and spicier notes due to the Skunk component, Royal Queen Seeds’ Amnesia Haze shifts clearly towards the citric acidity of limonene, offering a more immediate and disorienting cerebral impact.

FAQ

How long does the post-switch stretch last?

Vertical elongation is prolonged and can last until the fourth week of late flowering. Plan your training in advance.

Does it easily suffer from mold at the end of the cycle?

Its flowers are long and relatively airy, which favors good internal moisture expulsion and reduces the theoretical risk of botrytis.
