Sour Tsunami is primarily a cross between Sour Diesel and NYC Sour Diesel, yet there are a couple of other strains in the mix as well. These include Double Diesel and Ferrari. This hybrid strain is known for its distinctive smell, sweet and diesel fuel. On exhaling, you may detect a bitter or sour smell, hence the name. Marijuana enthusiasts will recognize the signature diesel musk of its parent plant, while cannabis newcomers can appreciate the sweet undertones. URSA NOVA is liquefied THC Diamonds blended with extra concentrated terpenes called NOVA terps. We create our NOVA terps using a proprietary extraction method that removes all lipids, leaving only the pure, clear, single-source terpenes. URSA NOVA is made using only full-sun fresh frozen flower from Humboldt.
