Growers in Holland crossed a female Arcata Trainwreck, from Afghanistan, and male, Mazar I Sharif, from California, and created A-Train. This strain was bread for indoor grows and the plant structure is bushy with lower branches spreading out from below. Because of the branchy structure, netting is usually required to give proper support. The flowering period for A-Train is around 8 weeks. Some of the treatments are for migraines, depressio, pain and arthritis.
