Sweet Trainwreck Auto is a large autoflowering strain, with a sativa structure and long branches that grow from the bottom of the plant. This strain grows very vigorous and is easy to cultivate, although during the first weeks of growth it requires small but frequent watering so as not to waterlog its small roots.
