hello guys i just build this diy cool tube from a long piece of metal duct to fit my 400w mh becuz they dont fit in bake a rounds or hurricane glass. do you think this would be adequate? i plan on leaving it without the glass because i figure i will be getting more lumens, and i would e using it as an exhaust for my closet. i plan on hooking a 265 cfm blower to it. is this gonna work? without the glass? exhausting the room?
