Purple Trainwreck Sauce by High Voltage Extracts is the offspring of two very popular strains, Purple Urkle and Trainwreck. This sauce exhibits a rich aroma of bright citrus, pine, and lavender and the indica effects provides the consumer with a stimulating cerebral experience combined with full physical relaxation. Some say the flower itself tends to smell both sweet and grassy, with the sweet notes of the Purple Urkle dominating.
