If you want the best yield, try growing "light of nah" supposed to yeilding 800 to 1200 meters squared, one of the best yeilding strains, but is for moderate to expert grower
Honestly, it's all about the grower. You can take a seed from garbage weed, but if you grow it with care, and with the right materials, you can get mid or better. It's mostly skill or experience when it comes to growing.
