no prob,the fan is anough to create negative pressure so you can have a passive intake but i would recomend a fan to pump extra air in or co2,thats on my list in the future,one step at a time,lol.I also use a 10'' osalating fan for air movement,hope this helps

Yes, they work well. Sheet metal duct is also much more quiet than any kind of flexible duct. Less restriction to flow aswell.

So i got my 170 cfm inline fan and the carbon scrubber. I have to say for 140$ together was an amazing deal. The fan is a bit loud but KICKS some ass! the filter is amazing NO SMELLS!!!! Also the filter does kill the sound a little more than without. Very good pruducts love HTG supply. i have carbon scrubber attached 2 the fan which is pulling air through the scrubber and filtering it then pushing it out of the tent into the bedroom. Is this the best way to be doing this? seems to be how everyone else does it. But im concerned enough fresh air isnt getting into the tent because the tent is inside just a bedroom. So in actuality im just recircing the air in the bedroom though it seems to be working well.

Since you are only recirculating the air in the bedroom, you should have Co2 running. Currently, you're set up to eliminate the smell but you have no fresh air for your girls.
Can you pump the filtered air outside somewhere? It won't smell so that won't be a problem. Then the air in the house will be pulled into the tent as "fresh air" and the little air leaks around the house will be enough to keep things happy.

I do have a way to get it outside with some 4'' flex and a hole setup thru window.
Is it really crucial to have it venting outside though? Because thats also taking heat/ac out with it.. my tent has some neg pressure but theres 2 of these mesh 15''x2'' vent flaps cut into my tent. So my bedroom air is beign sucked into the tent and then would be going outside.
P.S. i dont think im experienced enough to introduce co2 to my grow yet.

It's extremely crucial IF you don't have Co2 set up. When the air is only recirculating in the house it becomes stale very fast. The plants use all of the Co2 in that air then that's it, they stop growing. If you vent outside, it creates a negative pressure in the whole house and Co2-rich fresh air will be automatically drawn in.
Yes, it sucks a little heat out of the house. But it's not really enough to notice.

If you DO have Co2 . . . you should recirculate, not exhaust to the outside.

Ok thanks and i DO NOT have co2 lol. Whats the most cheap effective co2 setup thats not ghetto

Cheap and effective is a difficult combination. To be effective you need a bottle or a generator. To control it you need a Controller. An effective Co2 setup is gonna run you about $600 (not including propane or Co2 bottle refills). A ghetto Co2 setup is a lot cheaper, and I'm sure you can find some voodoo method link somewhere.
If I were you, I would vent to the outside of the house and call it GOOOOD.

Here's a good setup guide. http://www.jasons-indoor-guide-to-organic-and-hydroponics-gardening.com/exhaust-fan-setup.html
And this is the controller I use: http://www.grozonecontrol.com/TV2_en.html It does NOT make my fan hum like my manual $40 rotary speed-controller. This controller will idle during normal temp and only jump to mach speed when the temps get up. And it can shut off at night if the temps get too low.
