I know the theory.... If there is no air exchange happening then there's no smelly air to go out side. But air molecules will permeate almost any material and once they do the smells they carried with them will end up outside of where ever they were supposed to be sealed. This is the same reason that a dog can be trained to detect substances that are sealed in whatever container they are concealed in. The air molecules slowly make there way through and eventually are detectable. Obviously a dogs sense of smell is much better than a nosy neighbor. However a grow room, especially a commercial one is creating much higher levels of odor than whatever a dog is usually trained to detect. I'm getting a little off topic but you guys get my point. Smells make their way through material, or do they? If a room is sealed with a vapor barrier does that mean odor isn't permeating it? Or does odor make its way through everything, but we humans simply cannot smell it? Or are large scale commercial grows simply not able to truly contain odors? even when built as truly sealed rooms.
I know alot of you guys have sealed rooms with carbon scrubbers keeping odor at bay. And alot of you will tell me that you cannot smell anything. But do any of you have true commercial sized sealed grows that are still odor free? And does any body have any real experience with commercial sealed rooms and there odor?
