I set up my room with the "lung room" as you call it and it seems like that is the only way to go!One room will run at night (the 1klights for heat)
And the 600w room will be during the day
Lung room in the middle veg is totally separate and not included in the drawing. The center room is a lung room where the room being used at the time will receive manufactured air from the lung room. All sealed grow
