Nightmare OG is an indica dominant hybrid (70% indica/30% sativa) strain created through a potent cross of the infamous OG #18 X White Nightmare strains. This powerhouse bud packs a hard-hitting 28-30% THC level into each tiny little nug and relaxing full-bodied effects that will leave you dazed for hours on end. The Nightmare OG high creeps up on you, hitting you a little while after you first toke before launching your mind into a lifted state of cerebral energy.
