Did you know that your plants can be harmed if they don't get an adequate supply of CO2? Or that an excessive supply of carbon dioxide can potentially be harmful to your marijuana plants? CO2 is a crucial aspect of marijuana cultivation that can hinder or permanently halt the progress of plant growth. When it comes to supplying your plants with additional CO2, there are certain factors you need to keep in mind. In this piece, we will share ways to optimize CO2 levels for marijuana growth.

It is essential to ensure that your plants receive a CO2 level above 250 parts per million (ppm). Any CO2 level below this measure can pose immense risk to them. On the other hand, exposing your plants to dangerously high levels of CO2 can be lethal. But why is CO2 cultivation essential for weed? It enables plants to complete the process of photosynthesis. Photosynthesis is the conversion of carbon dioxide into energy in plants. As the name and formula imply, CO2 consists of one carbon atom and two oxygen atoms. This is significant because plants require 17 essential elements to grow and reproduce, and hydrogen, carbon, and oxygen make up 95% of a plant's dry weight.

Many farmers suggest that adding CO2 to the cultivation room could improve yields by up to 20%. However, this guide will show you how to optimize CO2 levels for better weed growth and excellent results.

How to introduce additional CO2 to your garden

There are several methods to add carbon dioxide to your garden. However, many of these methods do not guarantee controlled delivery of the desired PPM. Therefore, we recommend investing in reliable equipment to ensure proper CO2 supplementation.

CO2 generators

CO2 generators offer an effective way to improve the carbon dioxide levels for your plants. These products, resembling outdoor heaters, burn propane or natural gas to produce CO2. They also emit heat, making them suitable for larger spaces and climate-controlled enclosures.

Compressed CO2

Compressed CO2, stored in metal tanks like propane cylinders or scuba tanks, can be delivered to your plants through emitters. Unlike generating CO2 on your own, compressed carbon dioxide is produced at a factory, eliminating concerns about heat generation. This makes compressed CO2 an excellent choice for small-scale growers.

What does carbon dioxide do for your plants?

Optimizing CO2 levels for your plants will result in increased growth speed and higher yields. With accelerated growth, you can enjoy bountiful harvests every year, resulting in bigger and better yields without experiencing dry periods. When CO2 is used properly, it increases the moisture content in your plants and enhances their resilience. This enables plants to withstand higher temperatures than they normally would without drying out quickly. As a result, your plants will thrive in hotter conditions, leading to improved growth.

Why use CO2 in marijuana cultivation?

There are two primary benefits of using CO2 in your marijuana plants: faster growth and greater yield. Additionally, plants store a certain amount of moisture and energy in their leaves, and CO2 helps release that energy, allowing plants to blossom. Most cultivators agree that unlocking this stored energy can lead to a 20-30% increase in yield, along with a relative growth speed increase of at least 15%.

What do you need to know before adding CO2 to your marijuana plants?

Adding CO2 will increase the humidity of your cannabis garden, creating a more moist environment. However, higher moisture levels can also increase the risk of fungus and rot. Moreover, uncontrolled release of CO2 can create a toxic environment for both your cannabis plants and yourself. A CO2 level of about 2000 ppm can harm your plants, and levels higher than that can be unsafe for animals and humans to breathe. It's important to remember that a quantity below 250 ppm will harm your plants.

Since CO2 is heavier than oxygen, it needs to rain down on your plants. Therefore, it's necessary to regulate CO2 levels to maximize its benefits without sacrificing the oxygen your plants require, and vice versa. In a nutshell, CO2 supplementation will lead to bigger, improved, and higher annual yields.
