One of the biggest strains in California right now is the Runtz weed strain. We were lucky to write this White Runtz review without any worries about receiving any fakes because we got it directly from Nero in the Bay Area. This Indica dominant cannabis strain is the Nero Cut edition, it's a cross between Zkittlez and Gelato. Nero is part owner of the Runtz brand. The White Runtz strain is basically Runtz covered in THC with the same sweet taste.
