Would these fans do the job (400W HPS).

That depends on how big you make your filter. It can be as small as a gallon jug or as large as a laundry basket. It just all depends on your needs. If you are concerned about the fans power, then just make the filter smaller and change the carbon more often. Good luck- Diz:rasta:

alright thanks man, HAS ANYONE OUT THERE EVER DONE MY 3RD IDEA?? Any other ventilation links would be dec too, im thinking of doin my cool tube/carbonfilter/exhaust, to save money and i dont wanna have to fuck around with having an intake/outake just specifically for the cooltube, then another for the air circulation. If i cant do this ill prob just make a homemade reflector and have a regular intake/outake. anywayz thanks for the help so far doggs.
