attic grow sealed room inside outer attic.
i want to know if anyone knows the best way to do the ventilation.
i have 2 x 6" in line fans.
1. i was going to hook one fan up to my 4" (all there is) roof inlet for my sewer pipe coming directly from the roof and through my sealed lights and vent the air in to the rest of the house to warm it as it will only be fresh air. but i am worried about water getting sucked in from the rain and being blown over the lights.
i will fit a durgo valve on to the cut lower half of the sewer inlet pipe to let the sewer breathe and to stop in coming sewer gases.
2. i was going to use the second fan as a passive intake directly from the outer loft area which is outside my sealed room and blast the smelly air up the chimney, with carbon filter of course.
my question is this.
would i be better just sucking the air for the passive fan from the 4" roof sewer pipe, if a little rain water gets in to the grow room i can wear that.
and suck the air from the outer attic outside my sealed grow room for the lights and in to the rest of the house.
also will there be enough holes and crevices in my attic to suck the fresh air through for the fans or will my attic go in to negative pressure as well as my grow room going in to negative pressure with my passive fan.
i am fkn puzzled.
surely someone can either agree with me or steer me on the right path.
also will the 4" inlet sewer pipe be enough for the 6" fan as i am sure i will not need to put the fan on full power surely.
