Sour Diesel has since become one of the most popular strains on the marijuana market, spurring a ton of imitations and hybrids trying to jump on the hype train. The true Sour D is a lime green color with fluffy pink stigmas and an incredible, almost unearthly-strong kerosene/lemon/skunk aroma which stinks through almost any container or grow room. While the flavor and aroma are legendary, the effects are also among the most potent you will experience when well-grown.
