Mazar I Sharif x Arcata Trainwreck
A-Train is a cross between two very popular strains of medical cannabis ? Mazar-I-Sharif (father) and Arcata Trainwreck (mother). It can be argued that A-Train is a truly worldwide strain, with the father originating from Afghanistan and the mother from California. The strain also had a quick stop in Holland where it was further refined for indoor growing.
