Search on Sea of Green or SOG.
You can go right to flower and skip veg, in fact there are articles written on 12/12 from seed.

You can grow in 6" pots and therefore what you loose in plant you gain in square footage.
in other words 12 full plants may yeild 12oz after full veg. 48 plants may yeild 12oz with no veg.

SOG is great for limited height and smaller spaces. i would n't think it works well with a sativa dom strain.

I have some links saved somewhere. If I find them later I will post them for you.
