Royal Haze Autoflower (Royal Queen Seeds) Feminized

Royal Haze Autoflower: Classic Amsterdam Genetics, Auto Speed

Royal Haze Autoflower is a sativa-dominant strain from Royal Queen Seeds, built on one of the most respected Haze lineages in Amsterdam cannabis culture. The cross brings together Amnesia Haze, Skunk, and ruderalis. Amnesia Haze is responsible for the cerebral lift and citrus brightness that defines the strain's character. Skunk adds resin density and punch. Ruderalis contributes the autoflowering structure, keeping the plant compact and cutting the timeline down sharply. At 20% THC, this sits in a solid daily-driver range: accessible enough for regular use, but not lightweight. Sativa dominance comes through clearly in the effect profile rather than the plant structure.

Fast Turnaround, Small Footprint

Seed to harvest runs around 10 weeks, which is the main reason to choose this over its photoperiod counterpart. No light cycle management needed, the plant flowers on its own schedule regardless of hours. Indoors, height stays in the 50-100cm range, compact enough to fit a standard tent without aggressive training. Per-plant yield comes in at around 40-150g, modest relative to a full photoperiod grow, but manageable for the size and speed. LST works well if you want to open up the canopy and push toward the upper end of that range. Topping is possible but not always worth the recovery time on a plant with a fixed lifecycle.

Bright, Citrus-Forward and Built to Energise

The aroma is citrus-led with a juicy, fruity brightness that carries through to the taste. There is an earthy base underneath, but the dominant impression is clean and fresh rather than heavy or dank. Effects follow the Haze lineage closely: energetic, uplifting, and euphoric with a cerebral quality that suits daytime use or a creative session. This is not an evening strain. If you want something that sits heavier and sedates, a more indica-dominant auto would be the better pick. Royal Haze Autoflower delivers the classic Haze experience on a compressed timeline, and that is its strongest argument.
