Ecto Posted April 21, 2022 Share Posted April 21, 2022 Hey, my tent is in my shed and was wondering if anyone has ever used soundproofing to dampen down the fan sounds etc?? 2 Link to comment Share on other sites More sharing options...
Superstealth Posted April 21, 2022 Share Posted April 21, 2022 (edited) Sound proofing properly will be really expensive, I would look to make a kingspan box to put the extraction fan in, then pack it out with whatever you have, ideally some rockwool insulation. The biggest noise though on your size though will be the noise the air makes going through the ducting, to combat this invest in phonic ducting, it is far quieter than the crappy cheap stuff, also fan silencers are pretty good. For air movement if your running an intake fan look at getting a diffuse air, they connect to the end of the intake and circulate the air without the addition of the extra noise a oscillating fan will make.

LA LUNA Posted April 21, 2022 Share Posted April 21, 2022 My shed grow room was lined with 5” cellotex insulation (same as kingspan just a different brand) + the shed had a 3” cavity filled with rock wool, I had a silencer after my extraction fan and you could not hear a thing in or out of the shed ! 4 Link to comment Share on other sites More sharing options...
Gaijin Posted April 21, 2022 Share Posted April 21, 2022 I have a "cabin" that will need more insulation. I'm sure it has some sort of basic insulation because someone was living in it for over a year. But I'd like to make it winter and summer AND soundproof. I'm hoping 50mm rockwool slab with a layer of thin plywood will be enough. The room I'm using is only 2.8m long. With the 50mm rockwool at each end I'll lose maybe 12cm overall length. That only leaves 28cm to split between each end of the 2.4m tent. It's going to be tight. Especially as I cannot extract through the top of the tent either as it will be jammed up against the ceiling. From what you say @LA LUNA, I might need to go for the 100mm I'll be interested to see what people think might be a minimum wall thickness to "silence" EC fans. I'll be using Phonic Trap ducting. Good thread @Ecto Hope we get some good info 1 Link to comment Share on other sites More sharing options...

Fucking knowledge right there!!!! Cheers brother 1 Link to comment Share on other sites More sharing options...
Ecto Posted April 21, 2022 Author Share Posted April 21, 2022 So when they say these fans are quiet they ain’t! My shed is just shed thick at the moment so I assume I’m needing to insulate? Whole shed or just round tent? How do I post photos? 1 Link to comment Share on other sites More sharing options...

LA LUNA Posted April 21, 2022 Share Posted April 21, 2022 When I first built my shed grow I was reading in to soundproofing and insulation and 1 cheap trick is decoupling, basically an insulated box in a box with a small cavity between the 2, obviously not so good if your struggling for width or height and need insulation for heat purposes like winter shed growers do. @Gaijin you’d be surprised how much soundproofing 100mm of insulation board will provide ! I did 7 years in my shed all year round with 5” of insulation board a thermostatic fan speed controller and a bit of heating in the winter, anything’s possible with a bit of planning ! no one heard or smelled a thing 6 Link to comment Share on other sites More sharing options...

Gaijin Posted April 21, 2022 Share Posted April 21, 2022 @Ecto RVKs are louder than ECs. Then you have the expensive silenced ECs like the vector 2. Out of my price range too But the AC Infinity EC fans are supposed to be pretty quiet - that's what I'll be using. Hopefully you're right @LA LUNA I'm going to open up the door and fill in the panels. Probably glue some insulation board to the inside of the door too 3 Link to comment Share on other sites More sharing options...

Can’t really afford 2 of these fans, could maybe splurge on one 2 Link to comment Share on other sites More sharing options...

Was going 4” in 5” out How much lighting have you got ? If it’s 600w or below I wouldn’t bother with an inlet fan, just a passive intake of the correct size if your room or tent has got some insulation round it a 5” RVK will be fine. 4 Link to comment Share on other sites More sharing options...

So will be 600w hps but probably only run 400w as tent is not massive, does a insulated box work for rvks? I can put a vent in the shed door and run duct into the tent for passive but how big if extraction will be 5”? 1 Link to comment Share on other sites More sharing options...
