Kush Co's Sour Power OG is bred by Karma Genetics. It's Karma's Biker Kush x Hortilab's Sour Power.  Sour Power, created by HortiLab Seeds, is a heavy-hitting combination of Star Bud with East Coast Sour Diesel. The buds feature an earthy, woody fragrance shrouded in an overpowering whiff of skunk. Sour Power earned HortiLab Seeds first prize at three separate High Times Cannabis Cup competitions.
