Pineapple Express is a cross between Trainwreck and a Hawaiian landrace strain. Trainwreck is a powerful hybrid known for its happy high and soaring THC levels. Hawaiian strains are thought to be mostly sativa and provide a spirited clear-headed elevation. Sativa-dominant, Pineapple Express provides a happy and euphoric high overall, along with a mellow increase in energy. Like Trainwreck, Pineapple Express can be quite potent. The THC levels in this bud often reach over 20 percent, making it appropriate for those with some cannabis experience.
