Exhaust fan question

I have a pretty big living room where my grow tent is. What happens if I don't vent my exhaust out of a window and just let it out into my living room? I use a LED light so it doesn't get hot from the exhaust. Is it bad to breathe that air in?

You risk being killed by LED toxicity if you exhaust directly into the room.
But I wouldn't worry about that. Just make sure your temps are all good, and you should be fine without a window.

As long as your room is getting a fair air exchange - none.....I would wonder about reduced Co2 in the room though.

Nothing ,
