About this format
Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.
From the supplier
Blueberry Pedigree, Auto Speed
Royal Bluematic (Royal Queen Seeds) carries one of cannabis's most recognised lineages. The Blueberry parent traces back to Afghan and Thai genetics, a cross that earned back-to-back High Times Cannabis Cup recognition in 2000 and 2001 as historical heritage context. Royal Queen Seeds brought that legacy into autoflowering territory by introducing ruderalis genetics, preserving the sweet berry character and indica-dominant build while cutting the grow cycle down to a compact, light-schedule-free format. The result is a strain with real pedigree, not just a convenient grow.
One Cola, No Fuss
Royal Bluematic grows to 60-100cm indoors, a footprint that fits comfortably in a small tent without any aggressive canopy management. The plant channels its energy into a single dominant cola with minimal side branching, so the canopy largely manages itself. LST can help fill space if you want it, but it is optional rather than necessary. Topping is debated with autoflowers and generally best avoided here. Seed to harvest runs 9 weeks. Outdoor plants yield around 70g per plant, a modest figure consistent with the compact structure. Indoor productivity is similarly restrained, making this a quality-over-quantity grow rather than a bulk producer.
Berry on the Nose, Calm in the Body
The aroma is distinctly sweet blueberry, closer to fresh fruit than anything earthy or skunky. That same berry note carries through to the taste, clean and candy-like without being sharp. The effect sits firmly in indica territory: a relaxing, physical calm that settles into the body rather than the head. It is not a strain that demands your attention, which makes it well suited to evenings when you want to switch off. Potency sits at a moderate level based on the indica-dominant profile, though no specific THC figure is published for this variety.
