About Trainwreck Automatic

Royal Queen Seeds built this autoflowering version of Trainwreck by crossing it with ruderalis, keeping the sativa dominance at 70% while adding the fast, light-independent flowering that ruderalis genetics bring. The effect leans euphoric and energetic, with a clear, motivating headspace alongside a creative, uplifted lift, the kind of profile suited to daytime use rather than winding down. THC runs 17.8% to 21.1%, plenty strong for an auto. It's rated easy to grow, staying compact at 80 to 140 centimeters whether indoors or out, and finishes flowering in just 9 to 10 weeks from seed. Indoor growers can expect 375 to 450 grams per square meter, while outdoor plants return a smaller but still respectable 70 to 110 grams each, making this a practical option for anyone who wants Trainwreck's classic energetic effect without a full-season photoperiod grow.
