I should add that the biggest numbers are SOG or SCROG rather than that kind of yield on a single plant.

I think you guys touched on that with the per square meter thing.

If you're going for fast, you plant a sh*tload of seeds tightly together and force them to bloom early - then start over.
It's quite expensive to do it that way if you're buying seeds - best to have a mum & do clones if you want to go that way unless you're loaded.

I'm sure there are people on here that know much more about both techniques that I do so I won't pretend to be an expert.
