ok what if i set my co2 line at the base of the plants and my exhaust (charcoal filter) at the very top of the room and just ran them at the same time. wont this cause the co2 to pass the plants get absorbed before the filter vents it out? im willing to turn the exhaust off but im using it along with my lights(aircooled) i don't want the temp to rise and cause stress while i run the co2.
