Thanks smokingbuds21, So do carbon scrubbers work or just kinda reduce the smell I was counting on the scrubber to remove the scent, it would actually be easier to vent to the outside. Thanks for the comment "not very well thought out" real mature. Thats why I asked for feedback. I was thinking of adding a couple attic fans to help reduce the temps in the attic. I am novice to growing but definitely not making stuff used to be a carpenter and electrician.
