600 watt 3x3 scrog grow question?

Im going to be doing a 3x3 scrog grow, with 9 plants arranged in a 3x3 pattern. Im just wondering how big of pots should i get, and approx how long should i veg for? Its a soil grow, and the strains are female seeds white widow x big bud, and DNA genetics sharks breath. Thanks!

If your doin 9 plants in a three by three you shouldnt even need a screen. Veg those for 3 weeks and flip it. Youll stay short canopy should stay pretty even if your running the same strain for all nine

i dont think with 9 plants in a 3x3 area youll have room for anything bigger than 3 gal. pots
