I own both hoods and the Euro is awesomd but e. Its a little larger then I would've liked however is cover my space of 3'x4x lovely. I only have a HTG 6 inch fan with about 2 feet of ducting to dump the heat and everything worked out awesome. With just the 6 inch fan it cooled the temps atleast 12 degrees with the MH bulb and about 16 degrees with the HPS> bulb. The HPS created much more heat:thumbsup: Hope this helps!

ps The 6 inch inline fan is rated at 190 cfm. I am in the process of hooking up a 6 inch booster fan with carbon filter set up at the moment so I don't know exactly what woulb be best for you. However its more efficient to be sucking air out then pushing the air through. I'm going to hooking my carbon filter to the outake with a fan controller and get it dialed in.I'll throw in some more info after its all done this weekend
