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 : buena opcion
    Comment : no es la primera vez que cosecho esta variedad y solo puedo decir que nunca me ha defraudado tanto en calidad como en cantidad y muy pocas veces ha fallado una semilla, eso si, siempre sale una planta grande otra mediana y la otra mas pequeña

    Title : Royal Bluematic
    Comment : One of the best smokes ever from these, I grew 4 plants, one was done in 60 days (3.5oz), 2 were done in 68 days (just under 10oz), and one took 86 days and ended up over 2 meters tall (12.3oz)!!! All were more frosty with trichomes than I have seen in over 10 years growing. The smell of the cured bud is sweat and oily with musty undertones, A soothe and tasty smoke with a very potent stone. I am in love with this strain and will be growing more of these 100%. Another winner from RQS :)

    Title : Breitness gut, Geschmack eher mau
    Comment : Guter Wuchs. Im Vergleich zu den anderen Autoflowers, die ich hatte ist diese etwas kratziger im Rauch und hat nur sehr leichte Fruchtaromen im Hintergrund. Typische Indica Couchlock-Breitness :)

    Title : Very strong for colder climate!
    Comment : Got about 55 dry buds from plant grown outside, at first 3 weeks plants survived cold weather, three weeks in a row temperatures at night dropped at 5 degree celsius, and no problem they survived and weather got better and still 55g per plant dry, average, at the end of plovering top colas got dark purple/blue. I have testest different options and the best is to germinate them directly in a soil. Effect of this strain is my favorite of every eutoflowers i have grown. Energizing and eases my depresession syndroms. medical for me! five stars!

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.
