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

From: ExoticRainforest <Steve at exoticrainforest.com> on 2010.02.15 at 13:20:10 Thanks Steve.  The idea appearsfrivolous but your observation makes perfect sense.  I had two peoplegive me a scientific answer yesterday and I'm beginning to work on anew page for my site that will hopefully explain the myth and thescience..........but I still need more good input! Thanks!

(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?)SteveOn Sat, 13 Feb 2010, ExoticRainforest wrote: I've been asked twice recently if plants can cause oxygen deprivation atnight if kept in a bed room.  I've never heard of such a tale but found abunch of posts on garden websites today that make that claim.  Can anyonewith a scientific background elaborate on this one?? -- Steve Marak-- samarak@gizmoworks.com _______________________________________________Aroid-L mailing listAroid-L@www.gizmoworks.comhttp://www.gizmoworks.com/mailman/listinfo/aroid-l --------------000907040105030002030705
