WOW W/ that small of a room 1 lamp or 2? Any size filter should clean that air W/ 1 lamp.... What the Hell you Growing Skunks Fucking...LOL

How old is the Filter? They only last 12-18 Months.. If it is one of the Re-pack ones that you can Re-fill they have problems w/ them...

I'm using a 10" Can and that Kills Everything!!!

I would Upgrade if you live in the Grow Area... I'm not a Fan of those Ozone Genz they are Dangerous just like Plant had said before...

Good Luck GL1
