Right now I have 12 lights but im setup to run 16(walmart was out) so I guess ill just keep what I have for right now and see how that works...

for the exhaust I have a 250cfm inline fan and for the intake I planned on building a base for the cab then running another 250 inline fan for the intake which will come up from under the plants.... which should also leave me enough space to put a oscillating fan in there.. I also planned on cutting 1/2" 3/4" holes between the lights to allow for hot air to escape easier...
