Leak test on aircooled hood?

    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?

    Just assume its leaking, they often do when you suck through the hood. Tape it all up.
    Its unlikely your filter since its not even in the tent.
    You could turn all circulation fans off and only run the hood extractor and light up a joint and watch the airflow.
    Or use an incense stick and watch the smoke.
    Smoke bomb with live plants sounds like a bad idea. Plus the amount of smoke would overwhelm you pretty quick.

    If your using a cooltube then just swap the fan around so its pushing through the tube instead of sucking, but I assume your using a hood as you said hood, not as effective to push through.

    Hold a lighter to all the cracks. When you find leaks tape them with that metal foil tape for working on furnaces and ducting

    Lighting a joint sounds good. Lol

    I’ll give it a try.

    I use the vape, to check passive ventilation in the smallish cabs.....
