Question on mounting an inline fan/carbon filter

do1nth4ngs said:

I have a friend who says mounting the fan on top of the filter with the filter on the floor works fine for him......here is a pic this is a 4x4 tent with 6inch inline fan says the temps are fine and leaving another vent port open brings fresh air in.

Thanks much for the pictures, that helps me out a great deal. I am not so sure I would be able to imagine how to run that set-up, but now I see that it's rather easy.

So are you guys also recommending with my set-up that I go with an air cooled hood too? Help is appreciated because I plan on placing my order on Wednesday.

Yes and no. I hate to see you spend a lot of money if you don't need to. Air cooled hoods are good for obvious reasons, but it is another thing you have to make sure fits. You have to consider 6' ducting and a bend of some kind into the width. I like Gastankers setup where he had the light running one way and filter running perpendicular. BTW, how many watts are you running?

Yeah, I like Gastankers' set-up a lot too. Very ingenious. I am also hesitant to go with an air cooled hood because of the price. I am already on a tight budget, and I don't want to break the bank. I am planning a 400w MH/HPS. I have this light picked out with Agromax bulbs: http://www.htgsupply.com/Product-HTGSupply-Ultimate-400w-HPS-&-MH-Grow-Light.asp

i have a 4x8 tent and a 5x5 and this bad boy can refresh them both instantly. i have a ten inch inline fan. its ratd at over 900 cfm and it works wonders, had to do alot of modifying tho

Yeah, that might be a little overkill for my little 3x3x5 tent.

I have had my filter and fan this way for some time now, Works fine for me.
some more experienced growers i know have been doing it this way for years now.
Some even say that having the filter in your grow area (sucking)can suck the
taste out of your weed.
also, Its a carbon filter, i dont believe it cares what way the air flows imo.

Pulling air from a carbon filter is much more efficient than pushing air into it.

Have you made your purchase yet MJ?

No not yet. Wednesday is the planned day. Why do you have any suggestions before I pull the trigger?

I also think it's better to pull the air into the carbon filter because that is how it is designed.

Well not really. I think you have enough information to make an informed decision here. Me personally I like the idea of setting up like Gastanker suggests but it's going to be a tough fit I'm thinking too.

If you do go w/out the air-cooled hood and run into heat issues you can do what I did with my ac wall unit and tape ducting to the ac unit onto one of the lower intake vents. Looked ghetto but served its purpose.

Yeah. I agree. I think I am just sticking with the light I posted, and I will figure out how to run my carbon filter when it gets here. And I can totally see myself running my ducting from my AC if things get too hot. I really don't care if it looks ghetto, I just want results.

Thanks for the advice. That's pretty much the conclusion I have come to after reading a few books and reading all the posts here in my thread. I am going small for my first few grows, but when I move into a bigger apartment, I plan on expanding, but that won't be for about a year from now. My tent is 3x3 and is about 50 cu/ft. To remove the odor/heat I would need a 250CFM fan to remove the air 5 times per minute. My fan is 434CFM, so with my controller I can afford to lower the fan, reducing noise.

i like peanut butter!
