K2 often gets mistaken for the dangerous synthetic marijuana of the same name. The bona fide cannabis version of K2 descends from the White Widow crossed with the indica-characteristic landrace strain Hindu Kush. K2 is a reference to the Chogori mountain in China, the second highest peak in the world. No wonder, as K2 is reported by consumers to be a strain with high THC content. K2 features a smaller girth and height, perfect for indoor growers and beginners. At full maturity, K2 buds are compact and dense, featuring lime green and white coloring thanks to its plentiful trichomes. Growers can expect K2 to flower in eight to nine weeks.
