Royal Bluematic

This is our feminized autoflowering version of the famous Blueberry strain, known worldwide for its sweet berry flavour and aroma. We already had a great version of this plant with our Blue Mystic, but now we have an autoflowering variety to give you even more choices, plus faster yields of Blueberry bud.

We crossed ruderalis strains with the best genetics from the Blue family, which derives from a classic cross of Thai landraces, Thai hybrids, and an old-school Afghan bred by legendary breeders in California and Oregon. As a result, we have introduced the new and improved Royal Bluematic. Thanks to the autoflowering genetics, this plant is now easier to grow and can be harvested in just 8–9 weeks after planting the seeds.


Royal Bluematic grows to a medium-tall height for an autoflowering variety, averaging around 60–75cm. Like most autoflowering strains, it will grow very few side branches and dedicates all its energy to producing one large apical bud. On average, each plant will produce around 120g of delicious Royal Bluematic bud.

Due to its mostly indica genetics, Royal Bluematic has a smooth, relaxing, stoned effect. The flavour is much like our Blue Mystic, with a sweet smell and blueberry taste. It is an easy plant to grow, with a sensuous terpene profile and effect; the perfect combination. This new take on a beloved classic is much more than just another Blue imposter.

    Title : Disappointing
    Comment : I planted 5 of these seeds but only 3 germinated. Unusual for me to have negative results. Hopefully the remaining 5 will do better next spring.

    Comment : Habe knapp 2Wochen auf meine 3Samen warten müssen ..... zum zweiten sind alle drei bis heute (nach 7Tagen !) Nicht gekeimt .... Ich hatte bis jetzt mit anderen Samen eine 100%ige keimungsrate !!! Habe mich an den Support gewendet und keine Antwort bekommen bin ein wenig enttäuscht und werde wahrscheinlich den Anbieter wechseln !!! Nicht gut 23€für den arsch !!!! Naja Vllt kommen sie ja noch aber ist doch nicht normal das nach 7Tagen sich noch nichts tut ?!?!? Wenigstens eine Antwort vom Support kann man doch erhoffen wenn man sich mit einem derartigem Problem an sie wendet ?!?!

quanta luce deve avere al giorno? quanto deve essere grande il contenitore per la terra e la pianta? la germogliazione è obbligatoria?

Royal Queen Seeds Team

Please take a look at the below link for lighting information: Pot sizes ranging from 5-15 liter can be used. The size of the pot will have an influence on the size of your plants, on yields, and on the frequency you water your plants. Without germination there is no plant, therefore it is not mandatory but essential.
