Natural Options
You may wonder if there are any natural options for beginner gardeners. It isn’t always a good idea to buy expensive equipment when you are only a beginner. So, it is better to look at less expensive natural options. You may try the fermentation process. All you need is to combine water and yeast with sugar. This way, the fermentation will start and generate CO2. You may also try decomposing organic items. This method needs more time to clean everything. However, it is quite cheap and doesn’t require a lot of extra tools.
What Is CO2 Generator for Plants
First, let’s decipher the abbreviation. In short, a CO2 generator is a carbon dioxide generator. It is a specific tool that helps plants grow faster and maintain all the necessary functions in the greens. By increasing CO2 levels, the generator promotes growth. It is especially effective when you deal with closed areas. It may be useful for home areas if you are a beginner gardener. You may also apply this useful tool in greenhouses.
The generators are usually fueled with gas. You may choose from 2 basic options. These are propane or natural gases. The system within the generator isn’t complicated. The light is the basis of the system. The generators are used to grow different kinds of plants. You may use it for your beginner steps. However, it will also be useful if you get one for advanced purposes.

The generators may look differently. Some of them have to fit into the specific areas, while others are quite voluminous. The size of the generator doesn’t directly influence the quality and power of the tool. But in many cases, the bigger the generators, the more power they have to promote natural plant growth. But this is your choice to buy the generator that fits your key growing purpose.
What Is Hydroponic CO2 Detector
What is the role of a CO2 detector? If we take it shortly, a gas detector is a specific tool that focuses on correct gas concentration measurements. The detector will work with the metrics and identify the measurements in the device. There are different technologies used for hydroponic CO2 detectors.
The detector will work with the CO2 levels by providing complete monitoring of infrared radiation that is absorbed in the process. It is necessary to ensure the correct work of CO2 detectors. The quality of the air and other plant growth processes is dependent on the work of CO2 detectors.
On the market, there are different types of detectors. They all pursue the same goal but differ in the key technology. You may adjust your search to the needs of the plants and choose the best detector. The developers offer quite interesting and cost-effective options for customers, so you will surely find something for you.
What Role Does CO2 Play in Hydroponic Gardening
When you start gardening, you have so many different questions. The conditions differ because you may choose either an open or closed space for your plants. If you prefer growing plants in greenhouses, you should learn the importance of CO2 generator use. So, why is it necessary to use extra CO2 when you grow plants?
First of all, plants won’t survive if they lack enough carbon dioxide levels. For this reason, the use of additional CO2 is quite justified. When you have little CO2, the process of photosynthesis can’t be carried out correctly. Plants won’t show effective growing rates and may even die. When all the necessary components are available for the plant, it may generate sugar and feed itself. Without a proper CO2 level inside the leaves, the plant will cease to continue its growth.

Plants get a lot of components from the air. If the surrounding environment has enough carbon dioxide, the plant will satisfy its needs. But when the level is low, greens may show poor growing results. In the air, there are usually enough carbon dioxide elements. But you may work with closed areas where the levels are extremely low. For this reason, the use of a high-quality CO2 generator is a must.
BONUS: How Much CO2 Do Plants Need?
This is also a common question for beginners. When you plant different crops at home for your basic needs, you may overlook some necessary points and follow your guts. But when it comes to commercials, you need more in-depth info about the CO2 levels. No matter what your goal is, it is better to learn more about carbon dioxide levels.
When you make use of CO2 generators or controllers, you can monitor the lowest and highest metrics. But what is the desired level to help your crops get all the necessary elements from the air? If you deal with the ideal circumstances, your plant will need about 1000 ppm. But what if you don’t deal with ideal conditions, which is a reality for most gardeners?
In this case, you will need to ensure at least 800 ppm when you work with tomatoes or cucumbers or other raising seedlings. The levels may vary, depending on the type of the plant, some additional circumstances, and extra elements. If you want to choose the optimal level for your plants, you should take into account several necessary elements. Otherwise, you won’t produce impressive results. CO2 levels are important, but they aren’t the only critical things when it comes to gardening.

What Is the Optimum Level of CO2 for Plant Growth
When you offer a plant about 1000 pm for the whole day, it will receive enough energy and manage all the needed processes effectively. However, if you choose a higher level of carbon dioxide and maintain the same level during the whole day, it may kill the plants and ruin them forever. Thus, you need to monitor the levels. It isn’t easy to overdo the levels but make sure you keep track of the figures on your generator.
At What PPM of CO2 Do Plants Die
If you want to learn the minimum level, you are at the right place. Not to kill your plant, you should never set the generator at 150 ppm. If the level of CO2 is that low, plants start to lose their life energy and are unable to continue to process necessary functions. If you set the point even lower, the death of your plants is inevitable. So, you should always ensure that your greens have enough CO2 in the atmosphere around them.

But there are also so many other natural ways you can increase the levels of carbon dioxide to make your plants grow faster.
Where Should I Put My CO2 Generator in My Grow Room?
Where should you place the generator to enhance the circulation of carbon dioxide in the atmosphere? This is a tricky question for beginners. Well, let’s answer it. So, it is a well-known fact that CO2 is heavier than air. Thus, we may conclude that plants need to be placed below the generator. In other words, your task is to place the generator above the greens and plants. It is necessary to make an even distribution of the substance over the plants. This way, the method will work the most effectively.
How Much CO2 Should I Give My Plants?
This is a popular question because the level of CO2 is a tricky question. The issue is often discussed by the gardeners, and we want to give you a proper answer to this challenging question. So, on average, plants need about 1300 ppm to grow effectively. When you use a high-quality CO2 generator, it may monitor the levels and supply a defect of carbon dioxide easily. This way, you can be sure that the levels don’t drop fast.
How Do You Use a CO2 Generator?
Want to learn how to use a CO2 generator correctly? When you supplement your plants with carbon dioxide, you need to make the right choices. If you mess up with the work of the generator, it won’t do any good for the plants. So, let’s see what steps you should manage:
- First of all, choose the right light for prosperous growth.
- The next step is optional, and you can focus on your particular situation. Seal the space where you grow the plants.
- Make sure CO2 is above the plants, so everything is evenly distributed on the surface.
- When the night comes, you should turn off the system.
These are simple steps for beginners who know little about the work of CO2 generators.
How Often and When Should I Use CO2 in My Hydroponic Cabinet?
Experts say that the use of CO2 generators is optional. You don’t need to use the generators if you have other natural alternatives. It isn’t obligatory if you grow your plants at home without any commercial purposes. But if you decide to use the generators, make sure you keep up with the necessary CO2 levels and turn off the system at night. Put the CO2 over the plants so that it can be evenly dispersed on the plants.
What Is the Best Ratio CO2 for Night Time Hydroponic Cycle?
An expert thought is that you need about 1000 to 1500 ppm to promote healthy and effective plant growth in the closed areas. However, these are the approximate figures. Sometimes, you will need to reduce the power to adjust it to the current circumstances. When it is nighttime, you should turn off the CO2 controller. Otherwise, your plants will absorb too much CO2 and won’t be able to function properly.
Do Hydroponic Plants Require Much CO2?
On average, you will have to introduce about 1000 ppm for fast and natural plant growth. Can these figures change? Yes, they can change quite often. What does it depend on? First of all, it depends on the type of the plant. Different kinds of plants ask for different CO2 levels. But there’s a clear rule. You can’t set the bar too low and use a 150 ppm indicator because it will kill the flora. However, don’t use too much CO2. More than 1500 ppm can also be dangerous for your plants.
