what kind of ventilation would be good for me? :?:

I have a grow box im building that measures: 30" x 24" x 34" tall. Im using all cfls in the box. clone is going in on friday! :-P
 
bathroom fans are great i only use a 50 cfm bought at walmart for about 20$, i have 23w cfls, my temps are always between 22-25celcius, humidity is 45 depending on how many lights (heat) u can pick a stronger one, i think alot of peole pick the 100 or 150 cfm . i dont have an exhauts fan only a whole at the top left hand corner to vent , but my box is air tight so when i close the door it forces the air up and out via dryer tube so no light leaks. intake fan is in lower right hand corner. Keep it simple and have fun and it will be well worth it!!
