Now ive seen this on a few videos, people using wall air to vent the room.. like a closet. How effective is this? Could it be effectively used to vent to and from the room.. This would be for a florescent T5 setup. However If a 600w HPS was involved could this be done and work also? Or would the attic be about the only way? thanks
I would be concerned about the smell being sent into the walls if youre not using a filter of some sort. personally I say attic if you can, tried and true.
