Hey rayIm curious, and sorry if this is posted somewhere in here already, but:
Can you have no ventilation of fresh air, with a co2 setup and your plants thrive?
There are no in or out vents for my room, but my lights are vented with air from outside the room completely seperate from the air inside my room. This works because the room is filed with co2 from my 25lb tank, this co2 is the fresh air, I control temps with an ac unit. A split ac unit would make this room perfect.
