Re: [Aroid-l] Plants cause oxygen deprivation at night???????

From: Steve Marak <samarak at gizmoworks.com> on 2010.02.15 at 08:11:54(20592) I assume that claim is based on the idea that while plants' metabolisms produce a net surplus of oxygen, they do also use some oxygen, and that therefore at night (when not photosynthesizing) they are technically decreasing rather than increasing the oxygen in the room? I have no actual measurements, but my immediate conclusion would be that this is absurd from a purely logical standpoint, because anyone who sleeps in a room with another person (or pets, for that matter) at night has something with a much higher metabolism than plants using up their oxygen, and no one has any concern about oxygen deprivation in that situation. (For that matter, if it were true, even people with no plants in their bedroom would be suffocated each night by all the evil grass, trees, and shrubs outside ... where do they think the air in their homes comes from?)
