I'm afraid you are really really really mistaken. Please make sure to do research before you post or jsut make yourself look bad.. Blue Dream was bred by DJ Short to incorporate more sativa into is indica Blueberry plant. He ended up choosing a Californian Haze plant (one from San Jose), and through several years of intense breading he made a plant with the medicating effects of blueberry, with the uplifting cerebral effects of Haze. This proved a plant with genetic leanings between 40 - 60% Sativa. In other words a pure hybrid. Indicas generally have 18 - 25 % THC with 1.4 - 2.3 % CBD. Some people differentiate Afghanica and Indica, as there are physical differences and because Afghanica's have between 20 - 25% THC with .9 - 1.5 CBD creating a balanced effects. There are still plenty of pure genetics, and wonderful glowing examples of pure sativa, or pure indica, but there are also plenty of hybrids, And if Blue Dream is the most Sativa thing you have ever had please go get some good Haze. Or if you can find it Dr. Grinspoon. I happen to study cannabis genetics. Peace, DigitalAlch
