Cmh 630w or 315w in 4x3 tent

Hello,sorry for my bad english, in writing from non-english country in EU. So i need to know what is the best between cmh 630w and 315w for my Homebox 4x3x6. I really want HUGE colas organic. I will use the lamp with adjust-a-wing medium avenger. Now I use 400w mh/hps with lumatek electronic ballast but isn't enough.
Please help me.
Thanks!!

I use a 3x2.5 for my 315’s. But I think if it were me I would put two 315cmh’s two increase you light points
