ATF, also known more commonly as Alaskan Thunder Fuck, is an evenly balanced hybrid (50% indica/50% sativa) strain created through crossing a Northern California Sativa with a Russian Ruderalis before crossing it with the infamous Afghani strain. The result is a powerhouse of a strain that is perfect for those days when you need a little extra oomph to get relaxing. The high creeps up on you, suddenly taking ahold of your mind and leaving you slightly dazed with an intense feeling of euphoria.
