you roughly have 2-3 times more CO2 in the apartment than outside air

(source from a different MJ forum with a guy who had a meter to test CO2 levels)

You got a link? I would like to read that thread.

no it was months ago maybe you can find it thru google tho look up CO2 and Marijuana in conjunction :)

I like fanning in outdoor air from another room near the grow when it's cold enough outside to get away with it...This air contains between 0.03-0.04% CO2,(300-400 PPM),that naturally occurs in the air...Think I'm also gonna go back to fanning in some CO2,probably with the disposable CO2Boost,as I'm a ghetto grower who grows with an open closet during "lights on"...:420thought:

Carbon dioxide

Carbon dioxide (CO2)is a surrogate for indoor pollutants emitted by humans and correlates with human metabolic activity. Carbon dioxide at levels that are unusually high indoors may cause occupants to grow drowsy, get headaches, or function at lower activity levels. Humans are the main indoor source of carbon dioxide. Indoor levels are an indicator of the adequacy of outdoor air ventilation relative to indoor occupant density and metabolic activity. To eliminate most Indoor Air Quality complaints, total indoor carbon dioxide should be reduced to below 600 ppm above outdoor levels. NIOSH considers that indoor air concentrations of carbon dioxide that exceed 1,000 ppm are a marker suggesting inadequate ventilation. ASHRAE recommends that carbon dioxide levels not exceed 700 ppm above outdoor ambient levels.[6] The UK standards for schools say that carbon dioxide in all teaching and learning spaces, when measured at seated head height and averaged over the whole day should not exceed 1,500 ppm. The whole day refers to normal school hours (i.e. 9.00am to 3.30pm) and includes unoccupied periods such as lunch breaks. Canadian standards limit carbon dioxide to 3500 ppm. OSHA limits carbon dioxide concentration in the workplace to 5,000 ppm for prolonged periods, and 35,000 ppm for 15 minutes.

Thanks for the input all. I guess ill trash the soda idea. Just harvested two days ago and am pleased with the results.
