I am wondering how one would test a aircool light system. I am starting to get a bit of smell at lights on when the fan comes on to cool the hood. I have a carbon filter on the outside of the tent. Then into the tent and threw the hood then out the tent and out of the room. (This is the one getting smell) Also have a 4” fan and filter exhausting the tent out of the house. I want to test the hood and ducting before buying a new filter. How would you do this? Smoke bomb the tent and see is any smoke comes out?
