lol i have a 400 watt hid room... about 3ft x 4ft

i'm running 6".... i know what you are thinking... you can get better stuff cheaper, for 4"... but actually the fans are WAY more efficiant at 6", well making up the DIY costs
HighTillIDie Reviewed by HighTillIDie on . Is 4" vent big enough? In a 10' x 10' area, I have opened up my vent line and now have four inch open vents on oposite corners of the room. Does anyone think that this is good enough venting or should I open the vent up to 6"? SCIENTIXT Rating: 5
