Original Sour DieselHeadband
Indica-dominant strain with high production and a powerful, relaxing effect.
Cali Sour Diesel is an indica-dominant F4 hybrid that was bred by crossing Original Sour Diesel with Headband.
The huge production of Cali Sour Diesel easily compensates for its 70 day flowering period indoors; outdoors crops will be ready between October 15th - 25th in northern latitudes. This classic strain's prolific growth is quite astonishing.
Cali Sour Diesel exudes a sour lemon/citrus fuel scent and a creamy vanilla taste. THC production is around 21% and its effect is both intensely relaxing and a great appetite stimulator.
