Do you mean you just have charcoal sitting in your grow area?i just started my first grow on flowering a few days ago, i put a bunch of bags of charcol in the box, i read it a few places, not sure if it actually works, but it seems to be at the moment. though this is my first grow, not sure how strong the smell will get, if it doesn't work i like that glade plug-ins idea, i might just throw one in the grow box anyway
That's why I was asking if he just had it sitting in the room... wouldn't do much good.correct me if I am wrong, But I believe you need a specially charged charcoal in order to reduce the positively charged smells. It is also a good idea to put a venting system in with a charcoal filter on the end...
