So this friday i'm running down to pick up and install proper ventilation for my grow box.

The box is 4x4x4. I will eventually be moving and thus not even using a box after since i'll have a basement but for now I must do with what I got. So for a 4x4x4 room exactly how should I be setting up my ventilation? What cfm and mabey even a link or two to some suggested fans and a few details on how to implement them strategically. Hopefully keeping under a 300$ budget per say ?
