Well I bought a carbon filter with a fan attached to it and I swear the god damn thing doesn't work. I only have three plants left, but when I open the door to my apartment it is blatantly obvious I am growing weed. It reeks. I just got my seeds in yesterday for my next grow. This one I am finishing was my first btw. Now I'm debating how to best spend my money on equipment for this next grow. The smell problem has got to be solved. That is the most likely way for me to get caught. I am trying to decide if I should get a bigger tent and try to contain the smell in there and hook my carbon filter up to one of the vents on it. I'm sure that will minimize the smell. My plants outgrew the tent I have them in now so they are out in the open in my closet. I'm sure that's a big part of why the smell is spreading freely through the apartment. The other thing I am considering getting is an ozone generator. If you were in my situation would you go with the ozone generator or the larger tent for your next purchase? Both will help, but I can't make up my mind.
