100% agree, fresh air is very important and why I run with a window open (unless it gets too hot and have to close it to run AC). I also have ExhaleCO2 bag hanging over the table which I'm sure adds a little bit of fresh CO2 to the room as well.That is part of why I just keep running one strain over and over from clones off the previous batch.
It is amazing how humidity and temperature indoors, can affect the expression of the plant.
If you go unsealed without CO2, the best thing your room can have is an open window or door to outside for fresh CO2.
I also used to run the same strain from clones of the old clones over and over, and I did for years. Best ever yield I got was when I had the best ventilation from an open window on the third floor.
