training techniques?

I am wanting to grow in a single cola style, but still wanting to get about one ounce per plant. Planning on using clone at 12-15 in high right into 12/12 for small SOG setup. How exactly do you ensure single cola growth?

Grow them in small pots, and close together. Trim most of the lower branches so the growth will be in the main stem.
