First closet grow.. Lets see what you reefer pros think..

I have a 3x2x8 closet. The closet is right behind my bathroom so I am going to tie my exhaust fan into my toilet vent and I may filter it in the attic with a carbon filter, I know I am a genius, haha.... I am also going to line it with reflective material. My questions are how many plants can I grow in this size closet, will I need an intake fan as well as the exhaust fan, and do you guys think I will need a carbon filter so the neighbors won't smell it.. My closest neighbors are probably 100 feet away.. The room is so small I know I won't be able to grow many plants at once so I didn't know if the smell would be bad enough for a filter.. All your time and help is appreciated...

Having the filter won't hurt. Better safe than sorry sort of deal. And as for the number of plants in that space you could probably squeeze 4-6 small plants but honestly I would do two, maybe three, larger plants. Hope that helps.
