Read the quote once again TIH. I didn't say that 1000 ppm's of CO2 in the air will cause serious health problems, but levels ABOVE 1000 ppm. I used the 1000 ppm level as a ballpark figure, because in most studies, 1000 ppm is where the first signs of effects (on humans), however slight, have been established.
All people will react differently to high CO2 levels. A person with respiratory problems or other types of frail health will be the first to react negatively. I have no whatsoever idea how long time exposure of CO2 in the 1500 -2000 ppm area (where many growers fix their CO2 influx) will affect YOU.
