Sunsystem 150w hps

I seem to battle high temps a lot and I'm trying to think of a good way to air-cool a sun system 150w hps http://www.google.com/imgres?imgurl=http://www.urbansunshine.com/images/SS150H.jpg&imgrefurl=http://www.urbansunshine.com/index.php?main_page=index&cPath=233_234_239&usg=__WlQZ9aP8BHduqJShVHSEO9Gjpsc=&h=300&w=365&sz=12&hl=en&start=1&zoom=1&um=1&itbs=1&tbnid=N1vZ2lTO47tY9M:&tbnh=99&tbnw=121&prev=/images?q=150w+hps&um=1&hl=en&client=safari&sa=N&tbs=isch:1. Please help me think

I have a growlab gl60 with a 6 inch booster fan I'm trying to connect to ducting and cool the 150w hps some how. I need help

get a drill and a metal hole saw and cut the hood for the size u need

That's a pretty good idea. I was thinking about cutting out a square and screwing in a 4inch flange custom made kinda
