Royal Bluematic (Royal Queen Seeds) Feminized

Royal Bluematic: Blueberry Pedigree in a Fast Auto Package

Royal Bluematic from Royal Queen Seeds takes one of cannabis's most celebrated parent strains and puts it in an autoflowering format. The Blueberry parent carries Afghan and Thai hybrid heritage, a lineage that earned the strain multiple High Times Cannabis Cup wins in the early 2000s, and it's that same genetic foundation that gives Royal Bluematic its distinctive sweet berry identity. Ruderalis genetics bring the autoflowering trait, removing the need for light cycle management and cutting the road from seed to harvest down to 9 weeks. Indica-dominant by character, this is a strain built around flavour and ease, not just speed.

Compact, Self-Managing, and Done in 9 Weeks

Royal Bluematic stays between 60 and 75cm indoors, a footprint that suits small tents and confined grow spaces without any aggressive canopy work. The plant develops a single dominant main cola with minimal side branching, so it focuses its energy rather than spreading it thin. That structure means the canopy largely manages itself. LST is an option if you want to open up the plant slightly, but it's not required. Topping is debated with autoflowers generally, and given the short 9-week seed-to-harvest timeline, most growers leave Royal Bluematic to run its natural course. Outdoors, expect around 70g per plant, consistent with a compact auto of this size. Indoor productivity is more modest than larger photoperiod strains, so this is a quality-first pick rather than a bulk grower's choice.

Sweet Blueberry From First Whiff to Final Exhale

The aroma is unmistakably blueberry: sweet, fruity, and clean, with a berry depth that carries through into the taste. It's one of those strains where the flavour matches the smell closely, which isn't always a given. The effect is indica-dominant throughout, settling into a relaxing, physical calm that makes it a natural evening choice. There's no cerebral edge to navigate here, just a straightforward, soothing wind-down. If you're used to more stimulating sativas or balanced hybrids, Royal Bluematic sits firmly at the calmer end of the spectrum.
