    Hello so my question is I have recently bought a grow box 4x4x7 (112 cf) and I bought a 400 cfm coco activated carbon filter 6" duct fan filter combo. Will this be sufficient to clean the stank (one plant Scrog style), as well I have read that as long as I have a fan that is operating at twice the size of my space I don't need a intake fan so long as I have a intake slightly larger. This is know as passive intake active outtake system. I have read Cultivating Cannabis in the 21st Century by C.K. Watson. This being where I get my reference from.
     
    I will also be adding a CO2 bag to the box. I will be using a sunshine systems grow UFO for my lighting. It is a 90 watt LED. 
     
    If anyone thinks I will need to change my venting style please give your advise I will take it into consideration if what I have planned doesn't work. As for the main question do I have enough or too much air movement?
