Hey guys i need kind of a quick answer.

My ventilation system is quite loud....very loud. So loud that it may be worth investing in a silencer or muffler.

I need to know how good these "silencers" work.

Nordic Grow AB - Ljudd�¤mpare f�¶r fl�¤kt 125mm

They're not that cheap so i dont want to buy it if it's not going to work all that great. If u know anything about them, lemme know ASAP how well they work so i know if i should order it or not.

Happy smoking and Thank You,
