Ok as it seems, everybody agrees that the number one most important issue for growrooms is security. since i am moving into an apartment complex that is very large and i have a ridiculous walk in closet i will be doing my first grow here. i feel that my biggest securtiy risk is going to be smell during harvest. my question is if i were to put two carbon filters on my grow tent would the extra filter work or would it be pointless? how i was thinking to set it up is to put the carbon filter then flex ducting to one end of the air cooled hood, flex ducting from the other end of the air cooled hood to the inline fan, so the first carbon filter sucks the air through to clean it. then flex ducting running from the other end of the inline fan running outside the tent pushing air through carbon filter number two. would this system filter the air more effiently, or is that a big waste of time and money?
