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 : so sad
    Comment : but in water 20 celcius, 15 hours then wet towel methot on heating mat. 2 cm sprout placed in rapid rooter. grew till its 2th note then it stopped for 10 days, did not stress the plant at all, roots kept growing but the plant itself did not grow anymore, dont know what the problem is. watered with the same bottle so no ph stress dit not overpot constand 22/23 temp humidity 55-65% it has stopped growing now for 10 days. i dont know what the problem is if its just unlucky or genetics or me? this is not my first grow. i really wanted this strain becouse i liked everything about it. i have never seen this problem before and not 1 single user has this problem on the internet.... overal good genetics i guess? if it works.

    Title : 1 of 2 did not grow
    Comment : 1 seed didn’t germinate properly so I popped another and it’s only been 4 days and it’s about 2-3.5 inches tall it’s growing like a wild fire, even my royal jack and white widow auto didn’t grow that quickly, working on its second set of leaves although not true leaves this plant looks very very promising will post another review once I harvest!

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.
