Use the calculator below to determine the optimum CO₂ flow rate for your room.
Note: The calculator makes the following assumptions.
- Optimum enriched CO₂ level is 1500 ppm (adjustable)
- Existing CO₂ level is 400 ppm (adjustable)
- The greenhouse air exchange rate is 120 minutes
- CO₂ use by plants is 0.003 cubic feet of CO₂ per hour per square foot
