Highly doubtful ,
Plants need lotsa oxygen , living in a vacuums not cool . Look up midget louvers 4in. round / darkroom on the net . a place in Ct . If my memory serves me right you need 3 to 4 times the exhausts area = 6in. dia. for passive intake to be effictive . Latewood , Zandor , or Free Wheeling Frank may have the actual mathmatics to figure it out scientificaly .

xcrispi Reviewed by xcrispi on . ? about passive intake I've got a cab about 28"x43"x68"tall. Will 1 8"x8" dark room louvre do me, or do I need another? I've will have a 6" vortex pulling thru a scrubber and a cooltube. Thanks all Rating: 5
