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.
