I have read several articles on CGE rooms, and have seen some photos of how some were laid out. And it seems like a good way to do it if you have the time and money.
But there's something I don't understand. If the air in the grow room is never exchanged, doesn't it get old and stale and less effective? Even if the air is circulated to a seperate mixing room to have the CO2 replenished or whatever, wouldn't it be better to bring in a whole new batch of air now and then, like through carbon or hepa filters or something?
I could be wrong, I'm far from an expert. It just doen't seem right to me that the same volume of air is used nonstop for a whole grow cycle. But then again, that's kind of the point of a CGE room.
