MY attic ventilation

[kanehduhbuz]

have been informed that without proper intake/exhaust ventilation problems a plenty will develop + i am certainly experiencing that. :hairpull: my growing area is an upstairs bedroom, completely sealed in (as best i could) material on the bottom of the door to stop lite leakage, very difficult 4 air 2 enter here + there is no window. (sealed shut - cannot be used) a 10" vortex exhaust needs to vent to a 9" roof vent - i will be mcgivering a reducer + installing that asap. (don't no if it matters but - i run the exhaust 24/7 on a lower speed then crank it up to about 3/4 power in flower stage). as well, the attic has only 2 roof vents + i cannot be making any new openings anywhere. must work with what exists. ideas r most urgently needed, especially from the skilled trades people (thanks again van man) . (no CO2 is used in the manufacturing of this product). :huh: :aok: :ciao:

What kind of fan(s) are you planning on using?

attic ventilation now corrected + completed. - am now directly venting out (using a 10" exhaust fan) thru 1 of the 2 roof vents, + have eliminated the intake air vent entirely. i now obtain fresh air by dismantelling the air/lite blockage i had constructed at the bottom of the grow room door. a very strong, rush of air now flows up + into the room. excellent. new problem however - lite now escapes out the bottom of the door, need to work on eliminating this -
