CO2 Calculator

Calculate the time of injection of CO2 in BTUs.

Calculate the time required for your CO2 generator to reach the optimal level in a culture room.
Usually, it is necessary to fill the room after each cycle of ventilation or 3 hours during the "day".
Air contains +/- 300 ppm of CO2, the optimal target is 1500 ppm.
The use of CO2 must be done during the day cycle.
