Purple Haze
Broad profile25 listed sources
Purple Haze is a 70/30 sativa-dominant hybrid tracing back to a 1960s cross of Purple Thai and Haze. Its Terpinolene-forward terpene profile delivers a sweet berry-grape aroma alongside euphoric, creative, and energetic effects. With THC around 15-22%, it's a legendary daytime strain built for conversation, creativity, and focused momentum rather than couch-lock.

Sour Diesel
Broad profile26 listed sources
Sour Diesel is the East Coast legend that never faded. This sativa-dominant hybrid, most commonly traced to Chemdawg 91 crossed with Super Skunk around 1998, delivers a fast, cerebral rush that's energetic, uplifting, talkative and unusually focused. THC typically lands in the high teens to mid-20s, led by peppery caryophyllene with lemony limonene and earthy myrcene behind it. The nose is pure fuel — sharp diesel over citrus and skunk. A daytime workhorse for creative work, workouts and conversation, and still one of the most recognizable aromas in cannabis.
