About Watermelon Auto
About Watermelon Auto Cannabis Seeds
Sweet. Sticky. Super Discreet. Royal Queen Seeds’ Watermelon Auto is a tropical autoflower that delivers mouthwatering flavour and satisfying potency in a fast-finishing format. Bred from a fruity Watermelon Zkittlez lineage, this compact hybrid brings the beach party to your grow room with exotic terps and a balanced buzz that’s perfect from sunrise to sunset.
This is one of those strains you smell before you see. The terp profile leans hard into lush melon, mango, and tropical fruit punch – loud enough to turn heads but mellow enough to keep you grinning. Behind the sweetness is a high that’s smooth, happy, and ideal for creative daytime vibes or chilled evening unwinds.
