need ideas for venting

Ok so right now i'm workin in my closet it a 3ft by 3ft by 9ft i have 6 plants just fitting in there and i'm using cfls right now i'm going to be puttin in a 250watt hps system. And all i got right now for ventilation is a small 12in fan which i dunno if will cut it. The good thing I can leave the closet door open. So any suggesstions on a cheap and efficent way that i can cool down the hps system when i set it up? thanks for your time guys happy growing

I would have a seperate fan just for the HPS light. Then have the other fan blowing the air out.

Depending on how much you want to spend- you can get an air-cooled reflector to use with your light, get some flexible ducting and a can fan to exhaust the hot air from the reflector. Can fans (and squirrel cages) do cost, but maybe you can use an inline like a Suncourt.
