For light dampening during dark draped some 6-8 inch flexible duct out the vents with dust caps or nylons. One out of each side port at the bottom aliviates some of the negative pressure and brings in fresh air.
Ok thats good saves a lil money to get the vent covers
Anouther question
can I run duct work from a vent port to the cooltube then from the cooltube to a fan and out anouther vent?
Then use a fan filter combo the take the smell out the tent
