Amnesia Haze Automatic (Royal Queen Seeds) Feminized

Amnesia Haze in an Auto Package From Royal Queen Seeds

Amnesia Haze built its reputation in Dutch coffeeshops as one of the most celebrated sativa-dominant strains in the world. The problem was always the grow: notoriously long-flowering, demanding a photoperiod commitment that put it out of reach for a lot of home cultivators. Royal Queen Seeds changed that by crossing it with ruderalis genetics, keeping the cerebral, uplifting character intact while stripping out the light-schedule dependency. The result is a sativa-leaning autoflower that delivers the Amnesia Haze experience without the wait or the calendar management.

From Seed to Harvest in Around 11-12 Weeks

The ruderalis cross does the heavy lifting here. No light cycle adjustments, no flipping schedules, the plant moves through its cycle on its own timeline. Seed to harvest runs around 11-12 weeks, which is a significant step up from what the photoperiod Amnesia Haze demands. Indoor height ranges from 75-150cm, so the spread is wide: shorter phenotypes fit a tent without much intervention, but taller expressions will benefit from LST to keep the canopy manageable and stop the plant crowding the light. Outdoors, expect up to 150g per plant. The foxtail bud structure is a visual tell, elongated, stacked calyxes that are immediately recognizable to anyone familiar with the strain.

Spicy, Sweet, and Built for Daytime

The flavor profile runs spicy, sweet, and earthy, with the kind of depth you'd expect from a strain that's been refined over decades of Dutch breeding. The buds carry that same aromatic intensity that made the original famous. Effects are euphoric and cerebral, with an uplifting quality that suits creative work, social settings, or anything that benefits from a clear, energized headspace. This is a daytime strain, the sativa dominance keeps things moving rather than settling you into the couch. If you've grown the photoperiod version before, the auto format trades a little of the ceiling for a lot of convenience. If you haven't, this is a solid entry point into one of cannabis's most iconic sativa lineages.
