Thanks, what about the odor from the carbon filter?these are pretty vague questions. it depends on your settup. do you have a grow room, box, tent? i use a box so i bring in fresh air from outside the box from the room its in. some ppl have an entire room they often bring in fresh air from an adjacent room. some use air from outside. all you need do for "fresh air" is to exchange the air inside your "grow area" with air from another place. hope this helps a bit.
Where is everyone exhausting the air from the grow room too? Isnt it exhausted from the carbon filter?i dont understand the question about the carbon filter. what exactly did you want to know abt it?
Again this depends upon your set up. If you have a sealed room and are using CO2 then the carbon filter will discharge back into the room. If you are using an interior space with no access to the outside then you will be discharging back into living space.Where is everyone exhausting the air from the grow room too?
