Sativa dominant strains will be less leafy and more stretchy, with thinner stems. This strain I'm growing right now is a Gelato hybrid. Outside this last summer, this strain produced a 12 footer in my backyard. The seed definition said it was a 50/50 hybrid. From my experience, I felt this plant was more than 50% sativa because of the enormous stretch. The pictures are of my indoor grow right now, using the same Gelato seed. Again, same analysis goes for this plant. I topped it at 12 inches and it's grown to about 4 feet, with less leaves, thinner stems and more stretch than the Indica dominant strains I've grown.
