How did you reduce your noise of your grow setup?

I set up my first grow and the only issue I have is the amount of noise coming from the tent.
I tried putting the inline fan in a cardboard box filled with those shipping foam noodles and 60mil thick sound dampening foil and that didn't really do anything.

It seems the be the air moving the loudest part of the grow setup.

So my question is how did you reduce the noise?
I know there has to be someone out there that setup their grow tent in the same room their sleeping in and had to reduce the noise in order to fall asleep, if so how did you do it?

I'm debating if I should get insulated ducting, cost around $50 per 25Ft but the price doesn't bother me if it will lower the noise at least by 25%.

Let me know what you've done or what you think will work.

I just use 1 inline fan to exhaust 2 hoods and it seems a little loud, almost louder than my A/c.

maybe try putting something up in between the tent and where you are, i.e. like another tent wall or something that will physically block sound waves travelling towards you bringing doom. And then of course various materials will work better or worse. Imagine a giant quilt hanging between you and the grow tent, now that would block a lot of sound!

You can get a speed controller and just find the butter zone of where your fans pulling enough. If not youd probably have to get a silencer can to put near your fan. Not sure how well they work though.

What do you have your fan mounted on? I have mine mounted on a wood shelf off of a concrete wall, and have little noise issue.
I use my fan to exhaust 2 x 600 watt hoods, and I run it with a speed control at 50-60%, and that also helps with noise.

I think having it mounted on the metal bracket on the wood shelf is what keeps the noise down the most, but the speed control also helps. With the combo of the two you can't hear it anywhere except in the grow room area.

Good luck!

Put a thick piece of foam 1" away from the exhaust vent. Preferably Acoustic foam.

^ this.... ha, just kidding.

insulation, egg crates, squares of foam (sofa cushioning works great), setting things on carpet/rubber pads and make sure things aren't touching that will cause vibrations

I know that you can suspend the fan using bungee cords, letting the cords absorb any vibrations.

Good ideas I'm going to look into bungee cords and some type of cheap foam (SOund board foam is VERY expensive)
I'll do insulted ducting and see if it works, that should be the most noise to be honest.

What I'm hearing I'm almost 100% sure is just air moving and maybe I'm sensitive but its loud.
I can literally hear the air moving through the duct so gonna try insulted ducting first then bungee cords then some other methods

if you still have ideas keep them coming

They have generic sound proofing/reduction foam for really cheap. search the internets for it haha Something like 1-2 dollars for a square foot piece. So itd be like 10 bucks max to make a lil box. I grabbed some when i made a portable "studio" for recording. Works well and does what its supposed to do.

If not go to walmart/the cheapest store around and grab a pillow top insert for a bed. Theyre usually textured and around 5-10 dollars for a pretty big piece.

I have done some of the things people are suggesting here in the past, and some of these suggestions are more complicated solutions to a simple problem. See my previous post, use the mounting bracket your fan should have come with, install a simple shelf, screw fan to shelf, and get a speed control. I almost guarantee this will solve your problem, if it does not then get the insulated ducting. The bungee chord idea would probably be ok also, you basically need to make sure the fan is not touching anything that will conduct vibrations(noise)and you should notice a considerable reduction in noise levels.
Happy growing!

smaller, newer fans

Oversized insulated ducting is one way...ie...

4" inline fan connected to 6" insulated ducting.Not only does the insulated ducting cut out radiant heat from the hit exhaust air,it also cuts down on the noise of the air wooshing around in the ducting and being oversized it allows for better less restricted airflow which in return cuts down on even more of the noise of the air rushing around in the ducting.

Another good thing to add would be a carbon filter,and duct mufflers.
