How to use CO2 for optimal cannabis cultivation

Carbon Dioxide (CO2) is a chemical compound that fills the atmosphere in a gas state and is essential for healthy plant growth. Together with water and sunlight, carbon dioxide plays an important role for crops to create sugars.

The Role of CO2 in Cannabis Growth

Cannabis plants, like all plants, use carbon dioxide during photosynthesis to produce biochemical energy. In fact, carbon dioxide is one of the primary building blocks of plant tissue.

Benefits of CO2 for Cannabis Cultivation

Increasing the concentration of CO2 in the air around cannabis plants can help promote faster growth and higher yields. This is because photosynthesis is directly linked to the amount of CO2 available to the plant. By increasing the concentration of CO2 in the air, growers can help cannabis plants produce more energy, which can lead to larger and more abundant flowers.

Typically, cannabis plants thrive in an environment with a CO2 concentration of around 1000 parts per million (ppm), which is higher than the natural concentration in the atmosphere (around 400 ppm). Some growers use CO2 supplementation techniques, such as introducing CO2 gas into their growing environment, to raise the concentration of CO2 and boost plant growth.

However, it’s important to note that while CO2 can be beneficial for cannabis growth, excessive amounts of CO2 can be harmful to humans and the environment. Additionally, the use of high levels of CO2 in the cultivation of cannabis plants can be costly and energy-intensive. It is important for growers to balance the benefits of CO2 supplementation with the potential risks and costs.

How to Enrich Your CO2 using LED Lights

Typical CO2 levels for growing cannabis under high-PPFD (Photosynthetic Photon Flux Density) lights range from 400-1400 ppm and depend on the plant’s growth stage, as well as the light intensity and air temperature.
