Extracting into the attic

hi guys, need some help on this one..

my options for extracting air from the grow room and outside has slimmed down abit as wife went nutter when i was about too make a few holes straight through the walls on our house

only option left is extracting from growroom and directly up through the ceiling and into the attic..

any ideas how this air could affect the isolation on the roof and walls up there?
(humidity ect)

can you think of any other problems doing it this way?

also room is 8,8 x 7,2 feet and will house somewhere between 10-20 plants.

thank you in advance

edit: ah yea also.. think a charcoal filter is needed if im doing nothing but northern lights? seems like they dont smell that much.. i dont know though. my first grow

Standard building practices for a long time had all kinds of vents going into the attic. My house has a bathroom fan which vents into the attic, and that's 100% humidity right there after a shower. As long as it's a large enough space, and the attic is not a sealed attic (very important!)- you will be fine. As a matter of fact, that's where I will be venting my grow- into the attic. Just make sure your soffit vents aren't clogged, and even then you should have the main vent at the attic peak that is open.

So, yes, attics are a good place to vent your grow (again, assuming your grow isn't huge, and your attic is not a sealed attic).


P.S. when in doubt, always use an activated charcoal filter. There is no such thing as too much 'smell security'. That's my personal policy.

yeah I run the duct work all the way to one of the roof vents. Just to be safe

I accept, My house has a bathroom fan which vents into the attic, and that's 100% humidity right there after a shower

allright, thanks guys.

attic is an open type attic.

time too start some engineering
