darker green is an indica trait, as is broad leaves. If u get little skinny leaved with light green colored buds u can guess there is some sativa genetics. The high is the easiest way to find out, other than growin it. I smoked some stuff last week that was so damn tiring. I shared a j with one other person and I was burnt. I couldn't even keep my eyes straight and ended up going to my friends car to sleep.
