CO2 from Fermentation (Sugar and Yeast)

Second, the amount of CO2 produced by a 5 gallon bucket full of sugar water and yeast is not nearly as much as the amount of CO2 you actually need to bring a small 4'' x 4'' garden up to the ideal CO2 level (apx. 1200 to 1500 ppm). In fact, I would estimate it is about 1/5th of what you would actually need....and once you begin ventilating the grow room area to control the high temperature, your ...

CO2 Control In School Classrooms AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...
