The Gelato S1 strain is a "selfed" or self-pollinated version of the original Gelato cannabis strain, meaning a female Gelato plant was used to create pollen and then used to pollinate itself, resulting in feminized seeds of the same parent strain. This process produces strains with characteristics similar to the original, often described as an Indica-leaning hybrid with euphoric, relaxing, and mood-boosting effects, a sweet berry and lavender aroma, and a rich, flavor profile.
