Grow room vs tent

When I look up different ideas of changes I can make to my grow space the information seems dominated by tent growers. When it comes to ventilation, smell, and overall major differences. Is things like “fresh” air exchange as critical given the height and atleast 10x12 space

I don't know what you are getting at, but I do wonder how much does a plant need to breathe, and how does it breathe if a whooshing fan is pulling and sucking the mofo'in air out of the tent

Maybe it is better to let them chill, and scrub the exterior of the grow/tent

A fan isn't pulling the air out of the tent, it's creating airflo through the tent.

Co2 gets used up, heat and humidity builds up quickly for optimum growth you need regularly air changes, environment is everything.

Like mentioned it's all about ventilation. I prefer the fresh air in from outdoors and exhaust back outside, which is easier in a room. Unless you are looking for the total controlled environment which is a lot more work.

One of my grow spaces is a basement and atleast 25ft, for optimum “air exchange”. I need a really high cfm fan to exhaust and scrub. But all smells aside, other then circulation is it the density of plants in the Space that make intake of fresh air so pivotal
