I have a problem with my exhaust. Right now I have a house fan with carboard around it Blowing into a 3" tube that goes out the roof. My air flow is really low. Which in turn is makeing my heat really high. Like 93* hot.

My question is can I improve my exhaust rate by buying a pc fan that has a tighter blade to housing which should icrease my air flow out the tube?

Or am i screwed with that 3" tube and can only get so much air outta there?

It is of importance cause my heat outside is rising and if I dont gt this fixed I am done growing till fall. :shock::shock: Not what I want.

In the room I have motion fans and air movement

Please Help me out
 
your problem is your fan isnt strong enough to push the air through the tube. get stronger fans, a 4" duct fan should do well for you. or hook an extra pc fan up at the other end of the tube to help move the air. what lights are you running? at 93* you are going to need more than pc fans to cool your space down.
 
I had a 4" fan in it prior and it worked but still wasnt enough. I thought by placing a bigger fan it would work even better but i was wrong (obviously). But what kinda of fan is proper? And where would I get it. Like I said any help will help. Thank you
