Thanks for the tip and yes the plants do great in my room without any fresh air coming in.Nice grow it was fun to read through and see you improve skills. Have you realized that the air that you breath out is full of co2 for your plants? I spend 10minutes in my unvented veg room (led so not much heat) and co2 goes from ~800 to 1500ppm. They give you o2, and you give them co2. stop worrying about venting the place!
