Do i need an exhaust fan?....

I have a 2x3x5 wardrobe cabinet, and have a 250 watt mh light ballast and reflector. If i leave to doors open partially, do i need exhaust? I know i will loose some light but Wall lines with mylar, and i was thinking of keeping doors angled inward still, but open. Thanks

i would suggest some ducting out of the cab. a simple inline fan will be cool do you have any fans at all in there

yeah, MH lights do not get as hawt..you arent going to have any heatproblems i can almost asure you..but you always what the air in the room to exchange
