CO2 enrichment and its benefits

Cartier April 13, 2023

Cannabis cultivation has been around for thousands of years and has gone through significant advancements in techniques, tools, and technology. One such technique that has been gaining popularity in recent years is CO2 enrichment. CO2 enrichment involves increasing the concentration of carbon dioxide in the air surrounding the plants to enhance their growth and yield. In this article, we will explore CO2 enrichment and its benefits for healthy cannabis cultivation.

What is CO2 enrichment?

CO2 enrichment involves increasing the concentration of carbon dioxide in the air surrounding the plants to enhance their growth and yield. Typically, the concentration of CO2 in the atmosphere is around 400 parts per million (ppm). CO2 enrichment involves increasing this concentration to around 1000-1500 ppm. This increase in CO2 concentration provides more carbon for photosynthesis, allowing the plants to grow bigger and produce more flowers.

How does CO2 enrichment work?

Photosynthesis is the process by which plants convert light energy into chemical energy, which they use to grow and produce flowers. One of the essential components of photosynthesis is carbon dioxide. By increasing the concentration of CO2 in the air surrounding the plants, we provide more carbon for photosynthesis, which leads to an increase in plant growth and yield.

Benefits of CO2 enrichment for cannabis cultivation

  1. Increased growth and yield: One of the most significant benefits of CO2 enrichment is an increase in plant growth and yield. Studies have shown that cannabis plants grown in a CO2-enriched environment can produce up to 30% more yield compared to plants grown in a regular environment.
  2. Faster growth: CO2-enriched plants grow faster than regular plants. This means that growers can shorten the vegetative phase, which can save time and increase the number of harvests per year.
  3. Improved quality: CO2 enrichment can also improve the quality of cannabis plants. By providing more carbon for photosynthesis, plants can produce more trichomes, which contain the valuable cannabinoids and terpenes that give cannabis its medicinal and recreational properties.
  4. Energy efficiency: CO2 enrichment can also be an energy-efficient way to enhance plant growth. By increasing the CO2 concentration in the air surrounding the plants, growers can reduce the amount of light required for photosynthesis. This can save on energy costs and reduce the carbon footprint of cannabis cultivation.

Advanced techniques for CO2 enrichment

There are several techniques for CO2 enrichment, ranging from simple to complex. Some of the advanced techniques are:

  1. CO2 generators: CO2 generators burn propane or natural gas to produce CO2. These generators are expensive but can provide a consistent and reliable source of CO2.
  2. CO2 tanks: CO2 tanks are another way to provide CO2 to cannabis plants. These tanks are filled with compressed CO2 and can be used with a regulator to control the flow of CO2.
  3. Automated systems: Automated systems are the most advanced CO2 enrichment systems. These systems use sensors to monitor CO2 levels and automatically adjust the flow of CO2 as needed.

Conclusion

CO2 enrichment is an advanced technique for cannabis cultivation that can provide significant benefits in terms of plant growth, yield, and quality. While there are several techniques for CO2 enrichment, growers should choose a method that suits their needs and budget. With proper CO2 enrichment, cannabis growers can increase their yield, reduce the vegetative phase, and produce high-quality cannabis plants.
