After adequate control of the temperature and humidity climate conditions, the carbon dioxide or "CO2" concentration is the environmental variable that mainly promotes growth in plants.
A CO2 enrichment or frequent or even continuous air intake may be required to provide sufficient CO2 to plants to properly carry out photosynthesis. Below a concentration of 300 ppm CO2, the plants are not getting enough carbon thus making this gas a limiting factor to growth. Also, a CO2 concentration in excess of 2000 ppm cause plant transpiration and photosynthesis to stop.
In this category you will find dedicated controllers to control CO2 and smart controllers avoiding conflicting operations by integrating CO2 control to other functions.
