Purple Lightning apparently refers to two different strains, one a modest sativa-dominant strain and the other a potent hybrid with unknown sativa/indica ratio that resulted from a cross of Trainwreck and OG Kush. The first is probably the more popular, if only because the second Purple Lightning – our version – is hard to find. THC levels are unclear, and the same is true of CBD concentrations. But the strain's appearance and lineage suggests it's quite strong. The bud is light green with strands of purple and a heavy layer of resin-soaked trichomes. The aroma is musky, with tones of lemon, pine needles, and spices, while the flavor is similar.
