A classic sativa strain with THC levels averaging at 20-24%, Silver Haze is considered one of the most potent sativa strains on the market. Its effects are frequently reported as heavily cerebral, uplifting, and energizing. Silver Haze has two origin stories. Origin 1: Silver Haze by Sensi Seeds This Silver Haze originates in the 1980s as a hybrid of Silver Pearl x Haze. Silver Pearl is a hybrid of Early Pearl x Skunk #1/Northern Lights. Origin 2: Silver Haze by Shantibaba and Mr. Nice This Silver Haze originates with breeders Scott Blakey (AKA Shantibaba), Howard Marks (AKA Mr. Nice), and Neville Schoenmaker, who retooled their Super Silver Haze strain — a hybrid of Skunk x Northern Lights x Haze — and called it Silver Haze when they left Greenhouse Seed Company. Silver Haze won the bronze for Best Sativa in the 2005 High Times Cannabis Cup while its closest relative, Super Silver Haze, has won countless awards.
