New cabinet just sharing

The cabinet is 48x22x72 from the depot all white in and out with doors. I have 8 3ft 30w fluros and 8 26w cfl's there is a total of 17 plants but 9 are going outside as soon as the weather is better. 4 of the plants are short ryder feminized from nirvana. Being my first grow im lookin forward to the results. Any input would be great thanks for looking.

The last pic with the 3 cfl's im gonna be putting into the cabinet tommrow its 3 42w bulbs with an old MH reflector

I do have one question what would be the best way to vent this size of a cabinet meaning fans? Any help would be really nice
