Correct and I'm pulling from like a little attic everything is air tight I run 900ppm for veg 1500ppm for flowerSo you have your grow room, then you have another room that you pull air from? Just tryn to get a picture in my head. I can see how that closed loop would work if you have a 2 closed room that are being fed co2. So is the second room more just to have the air moving and cut the smell?
