Thanks so much for the head's up. That leads me to my next question...

If I am doing an active and passive intake system with computer fans, do I put the odor control there? How does that work? Do I use a carbon filter on the air that's going out? Also, can I just filter it into the room and it won't smell, or do I need to run some elaborate vent system into my attic or outside? I guess I am asking more so how effective the filters are. Thanks.
OneDayJD Reviewed by OneDayJD on . MAJOR n00b - question about smell I am thinking about doing my first grow in January. Therefore, I want to have all of my research done ahead of time. I am going to do a grow box in a closet probably with the Rubbermaid bin setup. My question is about smell. Obviously I need to keep this discreet and don't want my room and/or house to smell like pot the whole time I am growing. My question is when does it start smelling? Does it smell as soon as the plants start to grow? Or does it not start smelling until they are flowering? Rating: 5
