Dark Devil Auto is a hybrid marijuana strain bred from a Big Devil XL and a purple auto-flowering plant that was developed with the aid of Buddha Seeds. The purple character is inherited from a strain of cannabis growing in the Hindu Kush mountains of Pakistan. 

Sweet Trainwreck Auto is a rather taller-than-usual 4th. generation auto-flowering cannabis strain. It was bred by crossing certain 3rd. generation autos with an elite Trainwreck clone, the latter being extremely popular in US medical cannabis dispensaries.
