Black Diesel is a legendary sativa and Cannabis Cup winner several times over. Its NYC Diesel heritage can be seen in its impressive-looking flowers and intense stench. Advanced Seeds bred this strain for large yields and high THC content. Black Diesel isn’t as hardy as other strains in terms of mold resistance, but its well-balanced effects make it a fan favorite. Effects are initially sativa heavy, providing an uplifting, cerebral high. Eventually a body buzz emerges for a smooth, mellow high.
