Purple Trainwreck, also known as “Granddaddy Trainwreck,” “Granddaddy Wreck,” and “Purple Wreck,” is a hybrid marijuana strain made by crossing Trainwreck with Mendocino Purps. This strain is known for providing a stimulating, cerebral high that is anchored in physical relaxation. Purple Trainwreck has a rich aroma of bright citrus, pine, and lavendar. Medical marijuana patients choose this strain to help relieve symptoms associated with stress, anxiety and insomnia. Growers say Purple Trainwreck grows best in a warm, dry climate.
