I never suggested blowing air through the filter......I would set it up just as you have it drawn up. Having your fan suck air through the filter is more effcient the trying to push through it as suggested. It is easier on the fan to create the vacuum than have it force air through the filter and it also makes better use of the filters surface area.
Two things
The fan cant get the air any cooler than the intake air that coming in from outside so your temps will get hot if the outside air is hot with out any a/c cooling. If you have a tent set up or a grow room within a your shed dont draw air directly from outside. Draw it from lowest point of your tent (or the grow room) and let the temp stablize a little inside the shed area before it goes directly in your tent. If your using the whole shed as your grow room than i guess you have no other choice.
Second, make sure your intake from outside has some sort of filter to keep the bugs from coming in. This is often overlooked

I conquer!I never suggested blowing air through the filter......
Why???? I have an a/c in my back shed....I do work in there and it gets hot......but if you dont feel comfortable with that a portable a/c with an exhaust duct will work fine just cost a little more than a window a/c......if you are going to run a/c then your gonna have to cool your hoods with air from out side.....like this outside------->ducting------>cool hood 1------> ducting--------> cool hood 2-------- ducting---------->inline fan------->ducting------->outside like that you wont suck out all your cold air............it's not going to be cheap either...........now you need another fan for your carbon filter.....you can simply have the fan and filter recirculate air with in for odor.......are you gonna veg with the 1000's???That is going to be pricey on the electric bill....ever considered using fluorescent lights like cfl or what I prefer t8's........and you can veg in a separate area....that way you can have a perpetual harvest every 60+ days instead of every 90+ days....
Yeah it is the expensive but an effective way none the less......if it is cool in your area then setting up as he suggested would work fine that is why I asked the op if it gets hot where he lives repeatedly......I have tried every single way you can imagine setting up exhaust set up.....the method I suggested works best by far............if you live in a hot areathis is very much the hard way and expensive, you dont need all the fans. if his rooms sealed and he sets it up exactly the way he drew it up in the op then hes fine, thats all he needs minus the puck fan (whatever that is). im running the exact setup in a 4x8x7 tent. make the room sealed and cut a hole in the bottom on each wall for a passive intake. your tent should stay around 8 degrees warmer then the room its in.
Never said u didFilter should be at the exhaust end. Looks like you have it at your intake spot. Maybe just the drawing though.
I use a 270 cfm inline to cool a 1000 watt and a 400 watt light.........OK..I am gonna buy another fan just for my light. Whats the least expensive fan that will cool a 1000 watt hood? I already spent a bunch on the 720 cfm fan I will use for air scrubber and air intake.
Thanks...good thread. Ive been battling heat for days.
