500g/m2 means you can expect 500 grams from a square meter of plantS. A square meter can be any number of plants.
I think that estimate is based on those doing some kind of SOG grow. That's where smaller plants are jammed together
under a net of some kind. Mostly a pro or advanced grower thing.

this is what those numbers mean, but i like to tell new growers not to expect to get any yield, that way even if you yield say an ounce per plant or w/e, you'll be happier then say you were expecting 5 per plant..
and honestly, growing is not as easy as it may seem from the outside, and tons and tons of things effect things like yield, and it's honestly the one dpt i think i still struggle the most with after about 5 years or so of growing now.
i usually don't even pay attention to the numbers put up as honestly, they mostly are a best of type of thing, and like i said, tons of things come into play that can greatly effect yields ime..
