evening all, speaks for itself really. . . been trawling the diy section trying to find some way of making my own accoustic stuff but am to blind or to high to find anything. .

just got 10m of shiny 6' ductin for me new 6' rvk. . .i realize fowk say use bigger ducting than fan size but didnt know that at purchase time and am too tight to buy more. . . cost me over a ton for those
so how do i do it?? wrap the tubes in towels or sumit like that? i know theres a few creative minds out there, . .

e2a. . .for any spark minded ppl. . .am i right in thinking im puting a 3Amp fuse into my fan plug or is it bigger??

any1?
gona try do this today. ..

I would not bother fella be more hassle than it's worth.it's easier to buy other wise u have to make thousands of holes thru ur ducting then wrap in that itchy shit then cover it all again ball ache. U need the holes to let a bit of air into the middle to form a little air sock to deaden the sound I know it's exspensive as iv just got it .

You've bought the wrong ducting, if you want acoustic ducting you'll need to buy some.

suppose you could try the towel route like you say, it may help...no harm in trying it

you could also try wrapping the fan in a couple of towels and the tie it all up in one of them
bags you get from the sports shops ( the material ones with the string round top ) and cut a hole in the bottom for the ducting to pass through then tie it all up tight

although i expect that most of the noise will be the sound of the air rushing out the ducting on its way out

if moneys tight mate , experiment

cheers all. . . got my fan in a cardboard box filled with xpanding foam. . an idea i found on a thread by 'leepy' . .great idea!
duno what t do with ductin. . prob jus leave as is not too bad as is,

just set it up tonight and am puting final touch's to my grow room while my seeds finish cracking . . . should be starting a diary in cple days when i figure this camera thing out

3 amp should be fine

it's not the ducting that makes the most noise for me and i use normal ducting, it's the air being sucked in though the cf that makes the most noise, only way to reduce that is fit a fan controller


no, use the right size ducting as your fan or you could reduce/restrict air flow and have smell probs

yeah, thought the normal stuff would really vibrate so it would need some sort of cushion but its not bad now im up n runin
