Carbon dioxide, or CO2, is an increasingly used component of any professional grow room system. Although the last time you may have spoken about atmospheric CO2 was likely about how it is bad for the planet, CO2 is actually quite good (and necessary) for growing cannabis. It’s the heat retention properties of CO2 that contribute most to climate change. But for sake of your grow room, CO2 can actually be beneficial!

 

Below, we will review how to setup CO2 for your grow room, go over some CO2 equipment options, and discuss some tips for managing CO2 properly.

 

CO2 Supplementation Should Only Be Used When Growing in Enclosed Buildings

 

CO2 generators and compressors are certainly not the cheapest part of your grow room. So, you want to make sure that your hard earned carbon dioxide is not escaping your environment. 

 

In a grow room or greenhouse, your plants will deplete CO2 rapidly, so supplemental CO2 is important for heavier yields and better cannabis quality.

 

When performing CO2 enrichment, you must always make sure that your grow room operations are setup to contain the CO2 levels without it escaping your environment.

CO2 should only be used in enclosed spaces. It is not suitable for hoop houses or open greenhouse environments

Why CO2 Must Be Calculated With Your Grow Room Lighting

 

Plants can be damaged by excessive CO2. This is because CO2 is not the only source of energy in your plants. Plants also extract energy from light through the process of photosynthesis. When the balance between light and CO2 is off in your grow room, then this damage will occur.

 

Most grow room operators will utilize CO2 levels from 1,200 to 2,000 parts per million (ppm). Keeping your CO2 in this range should improve your yields greatly. You must also be sure that you are regulating your temperature and humidity when adjusting CO2 supplementation so that you have an optimal VPD.

 

It is crucial to note that CO2 levels of 3,000 ppm and above can be dangerous and even fatal for humans. When adding CO2 to your environment you must ALWAYS make sure that CO2 levels are within human health and safety standards.

Why Use CO2 In Your Grow Room?

 

CO2 has a multitude of benefits for your grow room’s performance. Some of the benefits of using CO2 in your grow room include: 

  • Higher plant yields
  • Better plant quality
  • More resistance to mold, disease and infection
  • More absorption of light 

 

If your are a commercial indoor grower, CO2 is something that you can add during the design of your grow room, or can be added once you’ve run a few cycles and paid off your initial investment. Do note that with increased yields, you will pay of your investment quicker when your run CO2.

Types of Grow Room CO2 Options

 

CO2 can be added to your grow room using CO2 generators or CO2 compressors. CO2 generators work by CO2 burners, while  compressed CO2 will release CO2 into the environment from storage tanks. Generally, compressed CO2 is best for smaller spaces, because it does not produce heat.
