Blue Haze is a cannabis strain that’s a cross of Blueberry and a version of Haze. Sometimes called Blueberry Haze, the strain’s true Haze origin keeps changing counting on who you pose the question to, some have declared that Blue Haze’s ancestry is in Amnesia Haze while others speculate its Super Silver Haze.
A popular farmer of Blue Haze, Zatvio Seeds, insists that its strain has a candy, fruity taste and fragrance, and THC levels of approximately 20%. The Sativa-leaning hybrid of Zatvio that develops tall with a slender body and is known to generate purple-blue buds soaked in resin in a nine-to-10-week flowering rotation.
A second breeder of Blue Haze is Homegrown Fantaseeds. At the 2001 High Times’ Cannabis Cup in Amsterdam, they won the first position for Sativa for the Blueberry and Haze combination.
This popular Indica-leaning version of Blue Haze is said to be easy to cultivate and generates an impressive calyx-to-leaf ratio, producing heavy, musky buds after a flowering cycle of eight-to-nine-weeks.
