Every seed ad ive seen states grams per m2... not grams per PLANT. Thats a yield that im sure they get from multiple plants stuffed into that given space. With maybe scrog and heavy lighting. And lets not forget that they make a living growing that shit so they probably can yield a bit better than the average joe. If you have a link showing your seeds with a yield PER PLANT and not a given area of grow space then please link it.
