My flowering side is almost setup.. All I have left to do is ventilation for the room. I can easily vent outside(to the right of the hps in the pics) and have an intake on the left side from the room next to my basement which is usually cool. The area that I am working with is about 2x4x6.5ft. According to an online calc the most I would need to exchange air once every minute is about 65 CFM. Both my intake and exhaust need to be in the rafters.
I was planning on using a 4" inline ducting fan to exhaust out.

I know that I need to have the intake fan have a lower CFM then the exhaust to create negative pressure. I was planning on using a 4 inch pc fan for the intake that is about 35 CFM.
Here is where I am kinda lost on the most efficient way to do this. Should I run ducting from the intake and through my hood to the exhaust? If I were to do that where would I put my carbon filter? Or could i also put that on a seperate exhaust? Also I'm guessing I would need to get a piece of glass cut for the hood as well.
I was also thinking of just having the intake blow into the room with no ducting and then doing something like fan > carbon filter > hood > ducting to exhaust. I really don't have a clue what I am doing here :\ any help or different ideas would be much appreciated!
