I don't mind helping you, otherwise what the fuck is the point of a forum...
There are several options you have: carbon filter, ona-gel products, less smelly plant strain matters a lot by the way, and certain dispersants that contain odor neutralizer that you have to refill. If you're going to use the whole closet and plan on growing more than 3 plants you will most likely get a combo of products cause one may not do it all. If you have an exhaust fan (or are you just going to leave the door open?) you should make a carbon filter yourself and attach it to your exhaust. But for a closet it probably needs a 4" or 6" inline fan to be really effective. Ona-gel products "kill" the odor using chemicals, it's used for industrial or commercial businesses that really have smelly offices (sewage plants) and I've heard poking a few holes in a bottle and keeping it in the room will work inside the room to kill odors. You have several options but I'd recommend more than one.
