Silly but thought I’d ask

Using a air cooled hood can I use a booster fan on one side with ducting out the tent for fresh cool air and ducting on other side of the hood to duct out the hot air separate from my ventilation

As long as the fan is strong enough, those booster fans aren't very powerful. I have used inline fans that way in the past and it worked well. You still need an exhaust fan for your room or tent tho. The one the through your light should be as closed to the grow as possible or can cause smell issues since it's not being filtered.

Or could I just add some ducting from one side of the light to my exhaust fan?

You can pull though your light with a filter on the other end of the hood and do all in one extraction and light cooling.
Used to be not recommended to do but the fans bearings should be fully sealed and the air is not that hot.

Or you can run independent fan for the hood but it needs to be independent of your room. Ideally taking air from elsewhere and taking it outside so it doesn't come back into the grow space or its defeating the purpose.

Whether you push of pull air through it recommended to check the hood for leaks in any joints and the glass.
If there are leaks and you pull through you will draw some unfiltered smelly air into the hood.

So it’s in a 4x4 tent
6 inch typhoon inline
I have the fan being exhausted outside through a window so the two top holes left is a 6 inch and a 4 I believe, I can’t do a fan on its own because of that Could I?
Or I could just add some ducting to fan to the light on one side and ive looked for the filters are people just using the filter sleeves?

^this is the easiest way with one light, I've done it with 2 lights as well, but when I stepped up to 3 lights it worked better to close the loop for the lighting and use two seperate fans.

But if I just did it to the fan no carbon filter(no smell yet how would I do it
