Smell Suggestions

I have a sealed room, 21 x 13 x 7 (divided into two rooms, veg/flower) I have a carbon filter in each room mounted on the ceiling, filter has a 6" inline fan (think 440 cfm) and the filter is 30ish inches long and 10" wide, would have to go measure to be certain.. but it does not seem to do anything for the smell. I keep reading people say just scrub the room with carbon filters and it will take care of most of the smell but its not, suggestions?

You need to make sure all the air is being scrubbed. Are you holding a vacuum in the room? HOw did you build the filter? You can buy a premade carbon filter from home depot. they are in the a/c filter isle. Just cut to size and put on with a rubber band.

The two filters are on the ceiling in each room, its not a homemade, its one from a local grow store.

are you "pulling" air through the filter or "pushing"?

You should be pulling.

I am pulling air through them

Duct the cleaned air to the other side of the room and use oscillating wall fans to circulate the air.

Exactly what kind of carbon filter do you have? It may be cheap china BS.
