Gold1answered grow question 1y ago There is no way to tell for sure. Usually you can get a pretty good idea by studying the morphology of the plant. Its for sure a hybrid, but odds are that if it displays straights of sativas (thin leaves, long flowering times, foxtailing) its most likely a sativa dominant hybrid. If it displays signs of indica (short flowering times, fat leaves, short/stocky nature) its most likely an indica dominant hybrid.
