There are many threads about odor control but one thing that is often overlooked is sound control. sound from buzzing ballasts, inline fans, wall-mounted fans, hydro pumps and/or many other things could be a contributing factor to someone finding out about your secret garden. worst part is that you wouldnt even know that they know! so if anyone has any ideas for sound control post them on here...
thing i have had recent problems with was an inline fan that shakes or
vibrates. this can cause hoses connected to your lights to shake loose or
even rip, eventually causing an air leak which will defeat the purpose of
having an air cooled system. it can also cause loud vibrations which is
the reason i created a housing for the fan;
this is pretty much what it will look like when it is
done. the bungees help reduce the sound by 200% so if you can hang it you
will be much happier.
first start by measuring the fans height and add an inch
or two then cut the wood for the box. if you are using 6" hose then cut a
hole on two of the boards that are 7" in diameter, these boards will be
the end boards.
next set the fan on one of the boards and mark
where the holes are on it, then drill them and mount the fan to the board
(do it now, makes it much easier).
once you have done all of above
go ahead and connect the hoses.
also you need to cut or drill a "V" in the side of the board
where you want the power cord to go through.
after that you can go ahead and put together the last couple
sides and you have a brand new silencer box for your inline fan.
