I wonder what the source is too? I doubt you could get co2 levels that high (not that it's super high) without supplementing in your home... unless you have a smaller home, very well insulated/air tight home, or you have lots of people/animals within your home. Like COPOBO said, a malfunctioning water heater or something to that extent sounds more likely. Not to mention, atmospheric CO2 is only 388ppm. I can sit in my grow room(which is only about 20 cubic feet) for 2hrs and the co2 ppm will go up to 2000ppm. Which is why I say it must be a small area. I don't know what your grow conditions are or where you're located, but it must be hard to control the other necessary "grow room" conditions with an adjacent window hanging open? Especially with changing seasons?


By the way, I believe it would be much easier to control ambient conditions via smaller areas... not larger ones. Why do many scientist/researchers do their test via small scale, rather than large? Larger areas take a longer time to acclimate than smaller ones, therefore smaller areas are easier to work with.

You're right though, it is wonderful. Although, I would call it the beautiful cycle of life. Symbiosis is defined as a relationship between 2 unlike ORGANISMS. Last time I checked, CO2 was an ELEMENT.

BTW, I know I sound like an ass... but I'm truly not trying to be one. I just don't know how else to word it. Sorry.
