This is the only post in here that makes sense...... Go jerry rig some shit up,,, I have used blower fans to blow air through (main lines) and then just drilled 6" holes for my light hoods, I still used 6" inlines though......It all depends on the setup. Bottom line, blowers are better if you want to push air, inlines are better for pulling it. Typically both carbon filters and vented hoods are designed to have air pulled through them. Therefore, inlines tend to be more popular.
