As of now I have the flex duct running into the grow tent with the exhaust fan on the outside pulling air out, then I attached the carbon filter to the opposite side ill try to make a quick diagram, my question is does the filter have to be inside the tent, the air being exhaust is being cleaned. []---------------------------F=C ^ tent duct F= fan, pulling the air from inside c= carbon filter
i believe it goes on the outside, because the air go's threw it making the ("stinky") air go out smelling "fresh"... for example... [----->]o--->
Supposed to have the filter on the inside of the tent, and supposed to pull stinky air through it. Not push stinky air through it. Theres a white pre-filter on the scrubbers for a reason, to suck air in. But many people do what works and what fits and push through scrubbers, including me, but its only a DIY scrubber. They say it also ruins fan motors from all the extra work it has to do when pushing stinky air through a scrubber.
