Purple Sour Diesel is a powerful combination of Sour Diesel and Purple Kush. Recommended for after-hours smoking, Purple Sour Diesel can pack some potent psychoactive effects along with a lighter physical high. The bouquet is fruity and, as the name would imply, can cross over into the sour zone. A THC content ranging from 15% to 21% rounds out the profile of this pungent strain.
