This strain might just be Delicious Seeds’ best breeding project yet. They’re incredibly proud of this strain. They should be, as this potent strain took over three years to breed properly. Their goal was to produce a better version of their star strain, Sugar Black Rose. They used a male Appalachian Kush in order to increase aromas and give the resulting plants’ structure more of an indica structure. It has a strong Kush flavor alongside metallic hints. Its aroma is earthy, citric and flowery, and its flavor is incredibly long lasting. Its effect is psychoactive and physically relaxing, capable of lasting for quite a while.



Gelatto is a strain that has completely taken over the market. How can one strain cause such a stir in so many different places? We’ve never seen anything like it, which is why you should grow Gelatto at least once – it’s the only way to truly understand how potent it is. It comes from a Thin Mint GSC plant and a delicious, refreshing Sunset Sherbet. The resulting plant is known for how intense and complex its aroma and flavor is, as well as its intense effect. It’s the perfect combination between psychoactivity and physical relaxation, which can be quite intense and long-lasting.
