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.
I've grown using 2 1000W HPS, 30 plants 4'x8' area, and have averaged 1 lb per 1000W.

I've grown using 4 600W HPS 40 plants 7'x8' and have averaged about the same per thousand, maybe a little better.

I only pick the shorter flowering periods, and flower 7 weeks. Hydroponics.
