Why is CO2 important for greenhouses

How much CO2 do greenhouses consume?

"How much CO2 do greenhouses use?" After you've asked yourself this question a few times, you must be one of the myriad others planning on speeding up the growth and development of your greenhouse plants.

In case you aren't aware, CO2 or carbon dioxide is an integral part of photosynthesis. Photosynthesis refers to the chemical process that converts light energy into sugar, which is used as food for your plants.

It is important to note that every time you bring in your crop, carbon dioxide is drawn from your greenhouse. For this reason, it is best to constantly replenish the carbon dioxide levels to keep the other greenhouse plants healthy.

CO2 use of greenhouses

Typically, CO2 concentrations are higher at night than during the day, as plants normally use CO2 through photosynthesis during the day. However, the rate of consumption depends on the plant variety, light intensity, temperature and the stage of plant development. In general, however, the CO2 consumption of plants can be between 0.12 and 0.24 kg / h / 100 m2.

Essentially, indoor operations or greenhouses should have carbon dioxide levels between 800 ppm and 1200 ppm. Other farmers use up to 1500ppm in their greenhouses, but there is usually a law in place that will reduce yields once they exceed that point. For this reason, many farmers choose not to keep their internal CO2 levels above 1200ppm.

Sufficient CO2 is essential for the plants to grow. Growers need to keep enough carbon dioxide in their greenhouses to ensure that the growth of their crops is not disturbed. In general, plants will not grow in an environment where the carbon dioxide level is below 250 ppm.

Ways to supplement carbon dioxide in your greenhouse

Thanks to the large surface area of ​​the environment outside of a greenhouse, plants can survive without supplementation with CO2. However, it looks very different if you grow your plants in a hobby greenhouse. Due to the limited space, they use the ambient carbon dioxide available in the closed space until the CO2 content is significantly reduced.

Carbon dioxide (CO2) is the process of adding extra carbon dioxide to a greenhouse to increase CO2 levels and improve the plant's photosynthetic ability. Studies show that increasing CO2 levels in a greenhouse by 800ppm to 1000ppm results in a 40% to 100% increase in yield.

If your sensors detect a drop below the recommended levels of CO2 (150 ppm to anywhere below 800 ppm), here are some ways you can add carbon dioxide to your greenhouse:

Method 1: Burning Fuels (i.e. Propane and Natural Gas)

One of the most common methods of CO2 supplementation is the combustion of natural gases and propane. These gases do not contain any harmful or dangerous levels of components. Hence, it is recommended to supplement carbon dioxide in your greenhouse. Burning 1 m3 of natural gas produces at least 1.8 kg of carbon dioxide, which the plants can use.

Method 2. Compressed CO2 tanks

Another common method of supplementing CO2 is through the use of compressed CO2 tanks. These tanks are released through an evaporator and the CO2 is distributed throughout the greenhouse through the holes in the PVC pipes. In smaller greenhouses, however, the CO2 can be released directly from the tank.

Method 3. Decomposition method

The decomposition method is another effective method that you can use to increase the level of CO2 in your greenhouse. With this method, all you have to do is put organic waste such as leftover food in plastic containers. Over time, the microbial effect in the substrate generates CO2, which the plants can then use. The downside to this method is that growers may have to deal with the smell and need a large amount of substrate to provide the right amount of carbon dioxide your plants need.

Benefits of growing plants in a hobby greenhouse

Hobby greenhouses are one of the most ideal places to grow your plants. One gives you better control over environmental conditions and ensures that your crops are grown in the right conditions. This in turn promises higher crop yields, higher harvests and more.

That being said, here are the other benefits of growing plants in a hobby greenhouse:

You can grow any type of plant

One of the greatest advantages of a hobby greenhouse is that you can grow just about any plant you want. If you want to grow a plant in the cold season in the summer or a plant in the warm season in the colder days, you can do it with a greenhouse. This is because you can control the temperature in the hobby greenhouse so that your plants can survive and thrive despite the cold or warm season.

Increased production

With a hobby greenhouse you can create the optimal climatic conditions that your plants need. You can even take carbon dioxide supplementation, which will greatly increase the yield of your plants.

Protection from harsh weather conditions and predators

Hobby greenhouses protect your plants from extreme weather conditions. Be it strong winds or heavy rain, you can rest assured that the enclosure will keep your crops safe and free from damage. Apart from that, hobby greenhouses also offer protection from birds, deer, squirrels and other animals that could feed on your plants.

Summary: How much CO2 do greenhouses use?

Plants need an adequate supply of carbon dioxide to grow and grow well. To ensure your plants aren't running out of CO2, you need to make sure that the surrounding carbon dioxide in your greenhouse is at least 800ppm to 1200ppm.

If necessary, supplement CO2 by burning fuel or by using compressed CO2 tanks in your greenhouse. A higher carbon dioxide content in the environment has been shown to increase crop yield by 40% to 100%.

"How much CO2 do greenhouses use?" The next time someone asks you this question, let them know that you cannot determine the exact amount as the number can vary depending on various factors such as the type of crop, light intensity and stage of development of the plant.
