dyno-mat , we used to use it in our cars back in the day to help keep in the bass, also kept loose parts from rattling

Hanging by bungees does wonders for vibrating fan noise. I've got that covered, but now the loudest part of my closet is the air pumps. Anyone have a good suggestion for getting rid of that annoying hum?

To force the plants to strengthen their stalks, but also to prevent molds, and to keep the warmth even.

If you have anything that sets on the ground or a shelf, you can make silicon rubber footies for the equipment. Just get a 2"x2"x4" tupperware container. Coat it with Pam, and fill it with clear silicon caulking from Lowes. Knock it out of the container after 12 hours. Let cure for 5 days, then place 4 under each balast, fan, or whatever. You can also use these when bolting something to the wall as a bolt dampener. This cut down vibrations in my attic from the point of not being able to sleep to forgetting I had a grow room :)

I live in a 3rd floor apartment, and I'm going to vent out a window that is about 20ft vertically and 20ft horizontally from a heavily trafficked walkway. I just bought a Can 8" HO 735cfm fan with a Can 75 filter. I haven't mounted them or run a ducting yet, but I turned it on just to hear it. Man, its pretty loud. I know I can reduce the noise with bungees and insulated ducting, and I really like that mounting box, but I'm worried about the sound of the airflow itself tipping people off. Does anyone have a similar sized setup? What does it sound like when you are outside in the vicinity of the vent? Should I get a muffler? I asked the owner of the hydro shop for one, but he said I didn't need it, even though he had them in stock. I figured he wouldn't pass on selling it to me unless I really didn't need it. Would a muffler reduce the noise of the airflow? What do you guys think? Please tell me something to ease my mind.

8' is going to be noisy mate! 735cfm is alot of air ! buy a speed controller imo, turn it down, also buy insulated ducting and try to get the out take end as far outside as you can to reduce to vortex noise.

I followed Hedge's advice and got the speed controller, now the system will only be as loud as I want it to be, Thanx again Hedge

Sounds control, odor control, vibration control, power control, heat control all that stuff is very important.

Sound - Gotta know how to build the system for sound control.

Odor control - Charcoal filters will do the job. Charcoal filters are used in the military to block a chemical attack.

Vibration control - Again, have to know how to build the system to control this.

Power & heat control - HPS lamps and LED lighting is the optimal type to use. I would stay away from LED lighting because tons of people are losing money. Very few led lights actually work.

Hey guys, I just moved to a new apartment this weekend. Went from a place with no worry about noise issues and now I am getting nervous about this new place.

My main concern is the humming of my ballast. I want to build a box for it and line the inside with foam. My concern is that it will get too hot. Earlier today I placed the ballast inside a cardboard box with towels wrapping the box, took care of the noise, but it quickly got too hot.

Any ideas? will a properly constructed box get rid of the heat issue?

I'm still living at home so i have no chance of hiding a growroom but theres a few plants at the side of the house. (my father smokes anyway so if he finds them he wont get mad, its my mother kicking me out im worried about).

One think i must ask is wouldnt people notice you carrying all this grow equipment into your new apartment? surely someone would see something when your moving in. Oh well.

replace chains with rope or strong string + anywhere metal is touching cover with duct tape n if u wanna go all out put housing insulation around the big fan boxes to reduce noise even more!!! or just throw a few bed sheets, the puffy ones over the grow box it reduce sound even more!!! worked a treat for me n costs nothing just time :)

Wow.. great thread...
Have just spent a good half hour soaking it all in..

Loving the box on the first page, however as mentioned earlier.. covering the inside of the box.. I'd use 1" flat sponge..
Hanging the box with rubber bands etc would be the best regarding vibration

I think the egg shell wall covering imo would reduce reflection of the light back on to the plants, however i recon if you put some in each corner then that might help a bit as well...
You got to remember though, where is the sound actually coming from i.e fan and ballast.

Digital / Electronic ballasts are much quieter than the magnetic ones that most growers seam to have..
hay also have many benifits like.. less heat, cheaper to run, more lumens per watt and of course almost silent.
The Lumatek in paticular would be the best on the market.


Also, I think someone was talking about noise from their inlet... why not try making a few inlets.. then air wont have to "woosh" so much through the 1 inlet..

I have to read up about varible fans speeds as I think some fans are not sutible for this due to the ball bearings inside..

Like i say.. good thread...:joint:

this is my method for the internal fan and the ceiling mounted extractor fan.

i simple suspend the cage fan in mid air with string inbetwean the lights and the top of the plants to reduce vibration noise.

for the ceiling fan i dont screw the fan directly into the ceiling i drop the air duct down into the grow room, attach it to the fan and suspend with string again, this cuts out nearly all the noise as before i did this it was screwed direct to the ceiling and it sounded as if there was a plane taking off in the room lol, hope this gives some people some direction and ideas for their own grow space, good luck n keep it quiet, ur equiptment and ur lips, lol. peace

Depending on the size of your room... Whats called " Muffin" fans can sometimes do...
I manage to get a few 4" and 6" fans..

I used the 4" for while but found the started to get a bit noisey for my liking.. so went to change them the other day for the 6" ones.... turned them on (dimmer switch included) and the room nearly took off...
So now back to 4" fans but this time mounted them to foam using a hot glue gun and then to a piece of half inch mdf screwed this to the wall of my grow room but also using rubber bands wraped around screws between the wooden plate and my room..
The result... Silence.. Cant belive how well it works... The hot glue works really well...kiss-ass
