I don't think there is a definitive answer dude. There are higher yielding strains but so much depends on environment , pot size, grower expertise, nutrients etc. There's guys getting 2 oz per plant from say auto mazars yet I've seen other guys get an oz from same genetics but because of one of the above factors it doesn't happen for them. You just gotta experiment til you find one that suits you and your circumstances. Run a multi strain experiment if you can to determine what's right for you. I done big bang auto based on the seedbanks yield claim and run a seedmakers automax at the same time, the so called big yielding big band gave me just over an oz the cheapo automax was 2.5 and I've ran them ever since. Just my 2 cents. All the best with your search for an answer buddy.
