best method?

i got 10 lowryder seeds. my growcloset is 55cm high 95cm wide and 40cm deep i have 300w of cfls(cold spectrum)il be buying flowering lights later.
what path should i take, should i get 10 5l pots and go sog or should i buy 14l pots and grow 3 plants at a time, which one would be better?
i would rather get more bud growing once since i am unable to grow during the summer, and i have just enough time to finish this grow.
so i would like to get as much bud as possible so to not run out during the summer, in autumn i'l be buying some other strain and go sog with clones.

Well if this is the only grow then you would need to do them all at once wouldn't you?

yes probably , how much bud would i be looking at comparing the 2 methods?
