CO2 calculator

Optimum CO2 levels & injection time

The Hydrotek Hydroponics CO2 calculator will help you determine the minimum required time to reach optimal CO2 levels in your grow room. Air naturally contains between 300 ppm and 500 ppm of CO2. The target for maximizing plant growth is between 1500 ppm and 2000 ppm.

Unless using a sealed room, the grow room must be filled after each air renewal cycle or every 3-hours during “day” time. CO2 should not be added during the “sleep” cycle.

The air already contains +/- 300 ppm of CO2
