All thru this thread there seems to be a misconception of what SOG is or does. SOG is a technique to grow many small single cola plants, usually less then 18" high when finished, in as short a time as possible (meaning little or no veg).

1 plant per sqft is not what I'd consider SOG. A minimum of 4 plants per sqft to a maximum of 9 plants per sqft is where it's at.
And lighting should be greater then some have suggested here, 600w per sqM if using HPS, I would consider more appropriate.

IMHO, SOG is the most efficent method of growing the most BUD, regardless of the type of light or grow medium used. When you start growing bushes and trees, you wind up throwing away stalks, branches and alot of leaves....all of which you put money (read electric) to grow. Why grow it if you are going to throw it away?

But there is a down side, to do this effectivly you need to run 1 strain with the clones comming from 1 common mother plant at a time. Trying to grow muli strains in the same batch, with the enhierent differences in growth rates and hieghts, will cost you effiency.

The other down side, as Rusty pointed out, in the good ole USA it probably is a felony. Actually 99+ plants and your're looking at a federal crime. The answer to that is live in an area where MMJ is legal and they base how much you can legally grow on canopy size rather then plant count. Or switch to SCROG, and shoot for a bud density of 4-9 buds per sqft.
