A got a few question for you VIC about how to vent if you dont mind.

I need help on how to setup my intake and exhaust, my room is 120 cubic feet I jus bought a can fan combo the fans rated 170 cfm, I have two smaller fans both rated 110 cfms for lighting i have a 400 watt hps cooltube. I also have a 7 inch ac hose from the house goin into my room.

So with all that how would you set up both light and filter?

Don't mind at all. One of the 110 cfms for intake, the can fan and carbon filter for exhaust, and the other 110 cfm blowing through the light and out of the room, don't forget the Oscillating fan to keep the air stirred up.
The 7" ac hose indicates a heat problem??
Put all of this in a journal with pictures and send me a link. the planning for your air handling system begins with were you can get intake from and where you can exhaust to. All of the equipment you have will make this simple,...... Maybe. VV

Thanks that is the way i thought it should be setup and i meant that i have a 7" A/C line blowing cold air in so my room temps are always around 75/Day 60/Night. I don't even know if i need the A/C I was told that if i have A/C blowing in my room that counts for intake that where i kinda get confused. I will get a journal up as soon as a get the time. I appreciate your help VIC.

You can not put more air in than you ae taking out, it has to be going somewhere, or you 7" line is at the end of the line. More than likely, once you have the air cooling for the light, intake and exhaust set up, your air conditioner maybe able to keep up by just cooling the room that this area is in. If not then by all means use the air, I have a portable one in my room. VV

okay so with your portable A/C do you still have an intake somewhere else. You get what i saying i just want to try to get a good understanding of the whole idea of proper venting. Again I appreciate the advice

Yes, I do. I have a 6" line with a cheap duct booster, the same one I used for this thread, with the same carbon filter covering it to filter out contamination. You are paying attention to the most important system and is has three parts, there are no short cuts, if you want to create a controlled environment, and use HID lights.
When your planning, remember bigger is better, an 8" line is almost twice as large as a 6" line. All exhausted air from a grow room needs to go outside, that applies to the lights air cooling system also, and all incoming air should be filtered to avoid pathogens and pests.
Rollitup posted three drawings of grow room design that show all of this, a simple setup, one more advanced, and his ultimate. It is worth a search. I used them for a class on grow room design. VV
