The History of Runtz Cannabis Strain: From Gelato x Zkittlez to Global Fame
Created by Cookies Fam in Los Angeles, the Runtz strain made its debut around 2017 and quickly skyrocketed in popularity.

This Sativa-dominant hybrid offers a balanced high, combining relaxation with euphoria, making it a favourite for recreational and medicinal users alike.
With THC levels often exceeding 20%, Runtz provides an energizing, mood-boosting effect perfect for daytime use or creative activities. Its candy-like aroma and colourful buds add to the allure, making it a visually appealing and potent strain that stands out in any grow room or dispensary.
