Question: are there any pure sativa strains?
Answer: The strains we know and love are all hybridized children. Haze, Blue Dream, and Strawberry Cough are all well-recognized Sativa dominant hybrids. Girl Scout Cookies, Granddaddy Purple, and Blueberry are all Indica-dominant hybrids. In short, there is no such thing as a pure Indica or a pure Sativa anymore.
