i got the inline duct fan your referring to.
its loud but its only on when the light s are
my exhaust fan is much louder.
i have a catalogue that has a duct "muffler" in it. it says it cuts down the noise by 25db but i dunno of anyone that has used one
wman44 Reviewed by wman44 on . Ventilation ideas. Ok, here is a pic of an idea for some light baffles i am thinking about building, since i currently have no intake for my ventilation. It is a light baffle system, where i willl be cutting out 4 square holes 4" x 4" on the bottom of a wall in my grow area and cover them with baffles i will be making, most likely out of tough cardboard. Take a look tell me what u think? Rating: 5
