Sour Blueberry is a Californian strain that is a cross of the famous Blueberry strain with a Sour Diesel #2. It is sativa-dominant and produces higher yields than the pure Blueberry by itself. It still exhibits beautiful blue colouration, especially when night-time temperatures drop significantly, and it has a deliciously fruity and acidic taste. It can be grown indoors and outdoors with good results and has an extremely pleasant, physically relaxing effect which makes it a good choice for those of a somewhat nervous disposition as it is very calming in that regard. Its THC production is at the higher end of medium coming in at around 14%.
