At some point in your marijuana growing career, you will have a desire to incorporate CO2 into your recipe. Chances are, that is why you are reading this article. I have grown marijuana for a long time, and I know first hand that there is a lot of junk information out there on the web in regards to marijuana plants and CO2. Below is some great information that I found on some of our partner sites that I wish I had when I first started growing marijuana.

Humans breathe in oxygen (O) and breathe out carbon dioxide (CO2). Plants do the reverse. They “breathe in” CO2 and “breathe out” oxygen (O). This is why plant life is an essential part of the worlds’ ecosystem. Without plants, CO2 levels would rise to intolerable levels. Plants use CO2 for growth. It is the essential building block for photosynthesis (along with light and water). Plants cannot grow without CO2. The current levels in the atmosphere are about 350 parts per million (PPM). It is theorized that millions of years ago, levels of CO2 were about 1,500 PPM. Throughout the years, plants have evolved in many ways-and in many ways have stayed the same. Knowing this can be advantageous for us all.
It seems that plants have not lost the ability to use up to 1,500 PPM of CO2. Plant growth can be accelerated by increasing the CO2 levels in your growing area. Conversely, CO2 levels below 250 PPM have a detrimental effect on your plants. If you have six plants growing in your closet, and there is no ventilation, your plants can use the CO2 in a few hours. They then stop growing. You must, at a minimum, provide fresh air for your plants every hour or so. An even better way is to provide supplemental CO2 for your plants by using either a CO2 generator or bottled CO2. Any of these solutions will keep your plants growing at optimal rates. It has been proven that you can increase your growth rates by up to 20 percent and size by up to 30 percent by providing supplemental CO2 at levels over 1,200 PPM. You should never go over 1,500 PPM, as this soon becomes toxic for the plants, and they tend to grow very stringy.
