Combine Orange Skunk with Jack’s Cleaner and Space Queen, and you get Agent Orange – no, not the Vietnam-era pesticide, but rather the medical marijuana strain. Agent Orange also known as “Agent O,” a sativa-dominant hybrid with a 75:25 sativa/indica ratio.  Agent Orange smells like citrus, naturally, and it tastes like sweet and spicy oranges, while the bud has a light green appearance.
