CO₂ Flow Rate Calculator

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
