How to Use CO2 to Increase Commercial Cannabis Growth Yields

Updated: Mar 30, 2023

co2 to increase commercial cannabis growth yields

Growing cannabis plants in large greenhouses or small growth centres is a highly-strategic process that requires skilled techniques and expertise.

To enhance this process, licensed cultivators have begun using carbon dioxide (CO2) to grow stronger cannabis plants with increased yields. This ensures that the growth of their cannabis plants leads to higher profits.

In this blog, we’re going to take a look at how the industrial gas CO2 is used in growing cannabis, how this technique benefits licensed cultivators and how you can use CO2 in your cannabis greenhouse.

How does CO2 work for cannabis plants?

Carbon dioxide occurs naturally in the Earth’s atmosphere as a trace gas. Plants extract this CO2 from the atmosphere and turn it into glucose. This glucose is used by the plant to grow bigger and stronger.

As a result, increasing the CO2 levels in your cannabis garden allows your plants to create more energy. Cannabis buds will grow larger in size with increased CO2 intake, which will in turn compensate for the need for more water, light and nutrients.

What are the benefits of using CO2 in your cannabis greenhouse?

Once you have introduced supplementary CO2 into your cannabis grow rooms or greenhouse operations your business will be able to accelerate yields, resulting in more harvests per year and higher profits.

Here are just a few of the key benefits of introducing additional CO2 into your cannabis garden:

  • Bigger yields and faster growth. C02 can make your plants grow up to 20 percent faster.

  • CO2 generators create natural smells that cover up the smell of your cannabis plants, enhancing your security.

  • Increased CO2 means you can grow your cannabis plants at higher temperatures.

How to introduce additional CO2 into your cannabis garden

The trick to accelerating plant growth is to circulate more CO2 into your garden. This can be done through a couple of different methods, either the implementation of ventilation systems or through compressed CO2.

CO2 ventilations systems can be set up around your greenhouse to automatically power on or off when C02 levels reach a specific level. This method is typically used for larger grow spaces and by larger companies who are able to invest in the equipment needed for climate control.

The alternative is the use of compressed CO2 tanks. This allows your cannabis grow op to introduce controlled quantities of CO2 into your greenhouse without the need for a ventilation system. This is typically used for companies with smaller growth spaces.

CO2 levels in our atmosphere are around 400pm. It is believed that CO2 levels increase plant growth upwards of 10,000, although caution must be taken as CO2 levels become dangerous for humans to breathe around 3,000 pm and are considered lethal at 2,000 ppm.

Most cannabis growth operations usually shoot for a C02 level of around 1,200 to 2,000 ppm.
