Anyone ever try 6" or 4" duct fans from lowe's??

i wanted to have two 6" duct fans from lowe's. the 6" is 250 cfm so two should be good for a 400 watt hps cooltube i would think ? two will be 500cfm. let me know if you tryed it thanks

I tried it on a cool tube 400w and it just wasnt enough. It all depends on how far you have to pull & push the air.

it will be less the a foot from the light to the fan to out my window so i think it should work no? pulling less then a foot from the light and pushing less then a foot before the light still to hot ya think?

only way to tell is try....everyone is different some depends on ambient air temp ...etc...I ended up using the 6" from lowes as an exhaust during veg then put in a can fan and carbon filter to exhaust during flower

I agree. Thats what im doing next. An inline fan and a carbon filter.

the 6" was ok for an exhaust but my setup at the time was so small i couldnt draw enough heat off the light

Are You exhausting outside with no filtration? Is this a stealth ? Not a good idea unless you are doing a med grow. I would suggest one of these from htg supply http://www.htgsupply.com/viewproduct.asp?productID=55183 or
http://www.htgsupply.com/viewproduct.asp?productID=52609 . Please use good filtration and you'll be much happier & safer with the results

hope this helps you

agree with goofygolfer better to just get a carbon filter now..you cold set it up to pull the air through the carbon filter and exhaust through the cooltube

I am a tite ass and have three bathroom fans from lowes.Its a big wtf but it works!

It's blowing outside a 3 story house blowing towards the woods behind ''my'' house and no one around me i don't think i would need a filter right?

build a carbon filter for under 20$ , search google, there are many designs you can do for very cheap. cheap insurance that wont get you caught, you know, easier to do it now rather than later

depends on how close your neighbors are and if you want to risk anyone smelling anything "questionable"....personally i would not take a chance unless you are in a med state

ok ok i found a cheap way to make one thanks everyone

read the tread - good answers. i like small and stealthy, and i use computer fans. how much air per minute - or day - do you need to move and filter.
my concern is efficiency so you don't blow your money around

I use a 6" 250cfm from home depot to vent my 400w air-cooled hood and it works great.

I use the 6" one, 250CFM is the CFM if it is used as a booster in a duct with the heater blower running, in free air / non-boosted setups its only 168cfm.

Saying that I use it only for my cool tube, I have a big fan for my room exhaust. My light intakes air from the garage, it's about 45*, goes threw the light and comes back out at about 80*, I can lay my hand on my tube anywhere except for directly under the arc tube and it isnt to hot to touch so I'd say it does a good job for that but I wouldnt use it as exhaust/intake for a room.
