This strain is a descendant of Alien Kush, an indica, and Tahoe OG Kush, an indica-dominant hybrid. The exact genetic makeup of Purple Alien is unknown, but its parentage suggests it's indica-heavy. The aroma is sweet and floral, with sweet hints of pine and soil, while the flavor is subtle but tart. The cone-shaped buds have a dark green color with frosty encrusted trichomes blanketing the surface. THC levels are largely a mystery, as are CBD contents.
