 Not understanding how to properly provide airflow to flower room?

So I just can't understand how to run fans and blowers in my room. I have a 3.5 by 3.5 by 7 ft tall flower room with one 600 watt cool tube hood reflector. I understand that I need a fan hooked to the cool tube to take heat out. But this seems like it has nothing to do with the airflow of the room. So does this mean I need another fan hooked to my homemade carbon filter to suck air out of the room? And then what about providing fresh air? Another fan? I've thought of connecting a t-connector so I can take hot air from the light and stale air from the room. Hook this up to the carbon filter and it could work. I just read that the more hosing you run the less efficiently your fan will do its job. Sorry for the thousand questions, please help a homey out. Thanks.

Well here was my last room...
1.calculate the size of the room
2.look up the definition of CFM cubic feet per minute and then find what CFM rating fan you need
Then you need 1 fan that will do at least that to move air out and one of equal size to replace the air removed with fresh air...
its pretty basic, not as hard as youre probably making it out to be

I remember someone had the set up on here. I am going to do the same thing. What you want to do is mount the carbon filter above the Cool Tube, run ducting from the filter to one side of the Cool Tube. Now attach ducting to the other side of the Cool Tube and run it out of the tent. Then attach that ducting to the intake on your fan. You will be pulling through your air through your filter and pulling the heat away from the light at the same time. Just have a office fan circulating the air inside the room on top of the other with its function.

let me try and field this.
you want it like this
thats ideal but you said you have a homemade filter so hooking it up that way may require some macguyvering.
the importent thing is as you pull air through the hood, either from a filter in-line or just from the space around the hood you are pulling stale air out at the same time. you don't need another set of inlet/outlet. you do want a fan inside the box to move air around, that keep the air around the leaves fresh.
it also doesn't matter which side the filter is on except that putting hot air through it may(i don't know for sure) release some of the smell, i know it does in my truck when i turn on the heater because the cabin air filter is saturated with blunt smoke.

Ideally you want it just like in the pic pha3r0 posted.
No one else mentioned though that you want your inline fan in between your carbon filter and cool tube. You want to suck air into your carbon filter, not push through it.
You want the fan before the cool tube. The reason is that you don't want to be sucking hot reflector over the internal components of your fan. This could cause premature fan failure. Plus fans lose efficency when sucking hot air.
Just something to keep in mind.

Wow! Thanks a lot! You just helped me to understand everything. So with the fan on one side of the light you suck air from the room through it. It travels through the light to cool it all off and travels a little way through venting and then through my carbon filter out my grow room. If that sounds about right there's less to it than I thought. Thanks again.

I would make it to where the air pulls through the filter first, then through the tube, and out the tent. I think filters are built to where they have to be at the end of the ducting but I may be wrong. Also I think excessive heat would be bad for the filter.
