New to growing. I need venting tips.

Well, I'm going to start on my grow box sometime during the week. And, the only question left is, how am I going to vent? I need to keep the smell in the box. But, I can't afford to spend anymore money. Is it really neccessary to use a Carbon Filter? Or, can I makeshift a filter?

You will need a carbon filter to keep the smell contained. If you have run out of money, you can do one of two things; either wait until you can scrape some coin together and buy a carbon filter, or make your own. Just Google it. They are even YouTube videos on how to make your own.

very much interested in the subject of ghetto ventilation
if you find any good videos post the links for me bro
