Watermelon is an indica-dominant cannabis strain — roughly 80% indica, 20% sativa — also known as Watermelon Kush or Watermelon OG. The breeder of record for Watermelon OG is not publicly confirmed, though its lineage is commonly traced back to a cross of Mendocino Purps and Hash Plant. What's undisputed is the aroma: a bold wave of ripe watermelon layered over tropical fruit, earthy undertones, and a subtle hashy funk that lingers on the nose. The flavor follows through with grape-forward notes and a lush tropical finish that fans of this strain won't soon forget.
Reviewers describe the experience as deeply relaxing, with many consumers noting a heavy, full-body calm that eases into sleepiness. Those who try it often report feeling happy and hungry — a solid pick for winding down at the end of the day. Enthusiasts also highlight the buds themselves: fluffy, pale green nuggets shot through with vivid pink undertones, bright orange pistils, and a generous coat of frosty white crystal trichomes that hint at what's to come.
