Blueberry Haze is a hybrid cross of Blueberry and Haze, this strain provides a sweet flavor and pleasant, euphoric high. Pace yourself with this one—overdoing it can send you to dreamland. For their Rosin, 710 Labs uses a solventless refinement process that presses the cannabis (hash or flower) between two heated metal plates. Done just right, the results are gorgeous golden-white or yellow oil or budder.
