CO2 Supplementation

CO2 Supplementation for plants can be greatly beneficial with regards to growth rate and yield. The current CO2 concentration in the atmosphere is around 416 PPM, but this can be boosted to concentrations of around 1200 PPM when growing plant in a controlled environment. Claims are made that CO2 supplementation can lead to up to 30% larger yields during harvest. Plants are also able to tolerate higher temperatures and more intense lighting when CO2 concentrations are increased.

Plants take up CO2 during the daytime through their leaves, and dry plant material analysis indicate that plants consist of up to 60% carbon, which makes CO2 supplementation an important point to consider.

Breathing in high levels of CO2 for humans can be very dangerous and even deadly, however, so great care must be taken and safety measures must be put in place when high output CO2 delivery systems like cannisters are used.
