Im considering intaking winter air on a thermostat/damper to keep 3k cool in a 6x13x7.5. Would this cause issues if done properly? I originally setup my Lights to intake cold air from outside and found out condensation was going to be an issue. Considering running no glass in the reflectors and help cool the room with cold air or insulating the duct run in hopes of fixing the condensation. Gonna be pushing it running 3k in this room
No, do not intake cold air directly into the room/tent, even if you fix the condensation, you are asking for powdery mildew, I've done it and lost an entire crop.
Bring fresh air into your lung room, keep the lung room at 68 degrees, and exhaust air directly from the lights outside. I like to keep the door to the lung room open or closed depending on how cold it is outside, to keep the lung room at the proper temperature. You don't want the lung room too cold or you will create conditions perfect for mold or mildew. Also, keep a dehumidifier in the lung room, I keep mine at 45% humidity and draw air from the lung room into both flower and veg tents. I keep a humidifier in the veg tent and keep the exhaust fans going 24/7.
