When I was really into brewing beer in 5 gal buckets, the plants I was growing in the same room under a HPS really responded to the increased concentration of CO2. When I was finished brewing beer, I continued the CO2 production by inncoulating a bucket of sugar water with yeast: 3 buckets in 2 or 3 day rotation. Given adequate light & nutrients, the plants REALLY respond. Normal atmospheric concentration is about 300 ppm. Plants can utilze up to 5X this concentration (depending on species) with a 33%+ growth rate increase.
