Im going to start growing in my 3ft wide 2ft deep 5 foot high grow room and ill have a 400W HPs light and going to use all Fox farm nutes and soil for 6-8 white widows with ventalation and circulation in the grown room i want to do a SOG will i have enough room? and im going to prolly add 4 CFL with the 400W HPS will i be ok need to know?

The 400w is all you'll ever need in that space.

unless its an air cooled 400hps that grow space will melt.
my space is 33"-36" by 72" high (a bit bigger).
i have an air cooled 400w hps and its still very hot with two fans blowing in.
