yes, dreamsweep just an fyi, it is looked down upon to jump into someone's grow journal and start asking questions about your grow. I recommend starting your own grow journal and trust me, as soon as you do a bunch of people will be happy to join in and help you, including myself. As far as your plant is concerned, she looks great, and perfectly a good size for that age.
oldboy, the filter connects directly to one side of the ventilating fan, and on the other side of the fan, you would have 4 inch ducting that would run right though the ceiling into the attic most likely. The pressure of the fan sucking the air will make the smell go nowhere else except through the carbon scrubber and into the attic, leaving no smell to escape anywhere else. its actually amazing. hahaha.
