If you use a large container like a 30+ gal smart pot one plant can grow a large enough root system to produce more than the small pots will. The trick is F I M'ing to get maximum bud sites and then training the plant so all the bud sites are in the sweet spot of light intensity, for maximum light exposure use 4 inx4in trellis. The down side is you get one strain the up is you get more product and a uniformed size buds.
