Omg this is exactly the question I was about to ask. Here is my homework i have done so far.
Im a first time grower, im actually growing my first plants from seeds and have had 7 seedlings grow their dented leafs and are about 5 inch tall after 2 weeks ou of 11 seeds.
Now my plan is to construct and btw have begun to build a 13 X 9 x 8. In my garage. Plan is to exhaust out of the attic while limiting the noise an heat as much as possible. Now after nailing down divisions and stuff in my garage i noticed that I was waking up my neighbors. (The asshole was in between my garage and his house in the dark squating to find out where the noise was coming from) so its them that I decided to condemn my 2nd door, towards my house instead of the farther one.
So since i am aware that there will be alot if humming and such coming out if such a room, I decided to read up on this.
Firstly, I found 2 solutions that may help. First is a component that replaces fiberglass (pink insulation) and use Roxul quietsound insultatiin sells at home depot, and secondly, ruber brakets where you mount your driwall on instead of screwing into the trust that eliminates the vibration transfer of sound.
It might be my first grow but I like doing things right the first time and am Optimistic.
Let me know if Im on the right track.!5
