LOL.. yeah I have one of those, and hate to burst your bubble, it doesnt blow even remotely close to what that 7" fan will blow even on the lowest speed. As a test I to ok the 8" booster and added it as an exhaust to my room, along with the 4" booster thats already there, and it still cant keep up with the incoming air. So your thoughts that the 8" booster is 10x the 7" fan is downright wrong, was downright wrong before you finished posting, as the numbers of CFM from the 7" are in the area of 800-1100 cfm.

stop it...
ever wonderedwhy there is more than one type of fan?! Ie barrel centrifuge prop ... its obvious isn't it different designs..
produce different results..

like yours WILL move volume probally even a touch of heat.. but trying to compare backyard design to fan manufacturers is jokable at best... I paid $38 aus and dropped temps 20 degrees ... its only 5 inch
but my hi volume ceiling exauht fan which is 10 inch didnt remove heat
.. but improved airflow

Alright... So I needed more airflow into my flower room, I do hav ea small 4" inline fan hooked up to one of my lights and pulls a good amount of air out, but my intake to the room was horrible, especially when I zipped closed my door... so I decided to look aorund for some air flow and had come up with some ideas... the one I finalized on was a 7" Honeywell fan, an 8"x24" metal duct. I took the metal duct which almost fit purfect in the outflow rim of the fan, used a single screw to make a perm attachment, screwing through the rim of the fan into the metal duct, then I took black duct tape and ran around the rim of the fan and worked my way onto the duct. This basically created a single unit of a fan with a 2 foot tube extension, which I cut a whole in an out of the way area of my room and slid the duct in leaving the fan outside the room. i dont know exact cfm of this fan, but my 80cfm 4" inline from home depot isnt enough to keep up, the airflow is pushing my panda film door open out like a bubble... looking at others and comparing then I would say this is probably a 800cfm fan.

Honewell 7" fan $16.00 at walmart
8"x24" metal duct $5.96 @ Home Depot
Large roll of Black Duct Tape $7.96
single metal self taping scew $0.08

Here is exact pictures of the items I used, I will post a picture of the final product once I can get one.

see that, ya got people followin your lead... NO MORE GHETTO INSTRUCTIONAL THREADS!!!!!!!!!!!!
What do you care how other people rig up their grow room. Not everyone can afford the same things in life. Or if they have things at their home they can utilize why not utilze them. I find that in this forum people jump on others simply for the sake of putting someone down. It's dispicable.

Good job on the this idea Reverof ... I have 2 of those induct fans and they are noisy... I hear them from my basement. I also need more air going in and have materials sitting around the house. My space would be considered GHETTO to some but I did it all myself and I am a female grower. Nobody sees it and it's not on display for anyone to see so who the fuck cares right.
