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 : Very constant genetic: 3 seeds this year, 3 last year, 3 two years ago...
    Comment : 100% germination (from packaging to soil directly) Fast grow and harvested in 70-80 days each time Outdoor, 11L or 18L, real soil from garden, nothing added except water Supported one very hot week without water (was on holydays) as well as another very wet/cloudy summer Usually between 40 and 60g dry (great considering making no effort at all) Berry taste is really present, smoke is sweet and compact One of my favorite so far !

    Title : Excellent service
    Comment : I've just successfully germinated the seeds I ordered, and all are coming along nicely. Royal Queen Seeds were exceptionally helpful when dealing with a problem I had with the delivery of the seeds. They promptly chased up the courier company who had misplaced my order and made sure I got the delivery at no extra cost. Very satisfied

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.
