Royal RuntzRuderalis
Very tasty and uplifting hybrid auto-flowering variety.
Royal Runtz Auto is a well-balanced hybrid strain that is a cross of the famous Royal Runtz variety with an outstanding ruderalis. Growers will obtain decent yields of uplifting and flavoursome buds.
Plants are on the shorter side of medium; indoors they grow to be 70 - 100 cm. tall while outdoors they will grow up to another 20 cm. or so. In 10 - 11 weeks from germination, soil-grown plants will be ready to harvest. Indoor yields are between 350 - 450 gr/m2 while outdoors each plant should produce 70 - 100 gr. each.
Royal Runtz Auto has a deliciously sweet fruity/candy flavour. THC levels are around 19% with low CBD delivering an effect that is both uplifting and long-lasting.

Royal Runtz Auto Feminised Seeds - 3
Both seeds popped nicely, and grew pretty vigorously. This was my first grow, but they produced quite a bit of flower. They held up to the hiccups I experienced on the learning curve.
