Looking good alex...I'd do exactly like GMT said with that fan...it's the best way to isolate the vibration..you could bring that light down lower..the heat is gonna go to the top either way...I cool the veg cab 175w Super MH with the outside-the-open-door with a vertical fan method..I have a cool hood on the 400w HPS with a 265 cfm Squirrel cage fan...at least 450 cfm would have been better..
Right on keep on rockin Alex
