600w Ventilation Question

Alright guys ... Long story short, I am feeling really frugal right now. At the moment I am planning on growing in a walk in closet that is poorly insulated. At this time of year, the warmest the room gets is around 77 degrees, and at night as cold as 60 degrees. The closets dimensions are (7*6*7). I am planning on purchasing a 600w lumatek ballast, Xtrasun 6" aircooled hood, and eventually a 400CFM inline fan to cool the fan / carbon scrub the room. Is it possible to go without the inline fan and use oscillating fans to compensate, or should I just save for the fan? I have a feeling if I were to get the 400CFM inline fan, I could get the hood really close to the canopy. Also, with regard to the hood, should I use the glass on the hood, or should I remove it? Thanks in advance guys.

....yes, get inline fans...yes use the tempered glass that come w/ the hood....without the inline fan and glass, your temps could possibly raise too high. Good luck.

Hey, thanks a bunch for the speedy response! Do you think 400CFM is enough to cool the hood and scrub the room?

...sure, you shouldn't have any problems doing that.
