TY sir

They are 6". I get absolutely zero noise from the hood or even the fan. The only noise is the air as it exits the fan...it sounds like what it is - a lot of air rushing by a vent. What I did was set an old air purifier I had on top of the cabinet near the vent and to a casual observer that explains the air noise.

I think the best way to air cool the hood is to vent from wall/attic space threw the hood back into the wall/attic space in another spot. it would require two seperate holes in the wall but if sealed properly you would not effect the ambient grow room air at all. the air in the attic or wall would keep the hood cool and you could use one more fan to exaust thwe man room with a carbon sok on it. I just did the easy rig vented wall to hood,,hood to a 4'' carbon SOK. so air passes Sok from room cools hood and vents through the wall.

not going to be ass effctive but you gatta go with what works

no its not as good as the harder way, who didnt know that right..lol but i tested it out and my peak temp was 83 which is high but doable. If i keep the door open i get 79-80. so being in that range and possibly adding a little CO2 later in 12/12 i think ill be ok
