CO2 Generation Tutorial – How to Add CO2 to a Grow Room – Expert Advice
Learn how to get the most out of your CO2 investment by following these steps.
1) Be aware of extractor fans
Is it necessary to extract air? Make the following adjustments to prevent your CO 2 from being sucked out by fans:
- Maintain a safe distance between any CO 2bags or dosers and your extraction ducting. As you dose, add some air to the mix. Make sure you have adequate CO2
2) Circulate air
CO 2 is much heavier than air. If left unattended, it has the potential to collapse and pool at ground level. To avoid this, make sure your air is mixed. This will ensure that the CO 2 level is consistent throughout your grow space. Something like the Quest F9 Air Moverwould be fantastic.
3) Add CO2 gradually
Attempt to gradually increase the amount of CO 2 available in your grow chamber.
4) Increase your feeds
Increased growth is a result of the addition of CO2 – make sure you have enough nutrients and water to sustain it by feeding plants more often.
5) If possible, switch off your extraction system during dosing
This provides plants with the opportunity to absorb significantly more CO2 during dosing. Fans should only be turned off for a limited period of time, and only if the temperature and humidity will not rise too high.
6) Don’t forget propane burners produce heat
When designing your temperature control system, you’ll need to take these factors into consideration.
CO2 and You: The Benefits of Adding Carbon Dioxide To Your Grow
According to my research, there are two primary advantages to employing CO2 in your indoor garden: increased yield and quicker growth. As an additional explanation, plants always have a certain amount of moisture and energy stored in their leaves. Carbon dioxide (CO2) assists in the extraction of that moisture and energy, allowing your plants to grow. Most growers think that accessing that stored energy will result in an increase in yield of around 20-30 percent, as well as an improvement in growth pace of at least 15 percent.
What is Carbon Dioxide (CO2)?
Plants breathe in a manner distinct from that of humans and other animals. In contrast to mammals, which take in oxygen and exhale carbon dioxide (CO2), plants do the polar opposite. This is one of the most significant reasons why plant life is such a vital component of the Earth’s ecology. CO2 levels would reach stifling levels in an exceptionally short period of time if plants were not there. CO2 is utilized by plants for growth since it is required for photosynthesis, along with light and water, in order for plants to develop.
Being aware of this is incredibly significant since the notion that increased CO2 intake can speed up plant development is supported by scientific evidence.
What do I need to know before adding Co2 to my grow?
CO2 will raise the humidity of your growing environment, which will result in the production of additional wetness. The more moisture you have in your grow, the greater the likelihood that fungus and rot will develop in your garden. A poisonous environment for both your plants and yourself can be created if your CO2 emissions are left unchecked, as previously stated. The presence of more than 2000ppm of CO2 can cause your plants to die, and levels higher than that can make breathing unhealthy for people and other animals.
- Consider the following scenario: you have six plants growing in your dressing and no artificial or natural ventilation is available.
- When the CO2 supply is depleted, the plants’ growth will come to an abrupt halt.
- To avoid these problems, you’ll need to keep your ppm levels under control by venting your grow.
- Fans and ducting will be required for proper ventilation.
- Another option is to utilize in-line fans that link directly to the ducting and exhaust the air out of your garden through exhaust ports in your yard.
- The problem is that when you vent your grow, there is a chance that the copious natural oxygen in your growing environment could overcome the Co2 and leave it ineffective, which is dangerous.
- The increased CO2 you’re providing your plants will accelerate the rate at which your plants will develop.
- Increased energy will result in greater temperatures in your growing environment.
- For example, if you’re using high-intensity discharge (HID) bulbs (such as high-pressure sodium and high-pressure mercury) in your grow lamp system, you’ll need to ventilate the space to keep it cool because HID lights release a lot of energy and heat.
With LEDs, on the other hand, you will not have to worry about the heat as much, but you will still need to ventilate your growing room in order to keep the ppm levels under control.
What does Carbon Dioxide do for your plants?
When used properly, CO2 may speed up and enhance the yield of your grow operation. With that level of speed, you’ll be able to harvest more crops every year, resulting in larger and higher yields without needing to wait for a dry spell. When a grow is able to make use of CO2, the moisture content of the grow is increased, and the plants’ overall resilience is increased. Plants can normally only live in temperatures below 70 degrees Fahrenheit, thus when maintained with Co2, plants will not dry out as quickly.
You may use a CO2 regulator coupled to a can of CO2 or a CO2 generator to augment the CO2 in your indoor farm’s atmosphere.
Researchers demonstrated that increasing and sustaining CO2 levels beyond 1 200 parts per million (PPM) can result in an increase in growth rates of up to 20% and an increase in size of up to 30%.
Using CO2 in Your Grow Room
As previously said, CO2 is heavier than oxygen, therefore bear in mind that CO2 will need to “rain” down on your plants in order for them to thrive. That being stated, there are three primary methods of introducing CO2 into your grow: a regulated tank of CO2 (regulated by a device such as ourCo2 Regulator), a natural supply of CO2, such as ourEZ-Co2Bag, or propane/natural gas burners. Generators of CO2 in the Natural Environment For smaller grows, natural CO2 sources such as EZ CO2 bags or DIY CO2 generators (such as a bubbler in one bottle of water producing and transmitting CO2 to another bottle for usage) are ideal.
- These CO2 sources, on the other hand, do not provide extensive coverage.
- The use of these products is advised for smaller grow rooms like as grow tents and closets.
- CO2 tank that has been regulated If you decide to go this route, keep in mind that you can get canned CO2 at most hydroponic retailers.
- All you have to do is set the required flow rate (measured in cubic feet per minute) and the timer to raise the CO2 levels to the appropriate level as soon as possible.
- It is advantageous to use CO2 tanks because, depending on their size and your regulator, you may stroll around your grow and manually fill the whole grow area with CO2.
- Using them is also somewhat less dangerous than using CO2 generators and burners.
- CO2 and water are produced as byproducts of this process (humidity).
- Most of the time, these generators are designed to create as little heat as possible while also producing the greatest amount of CO2.
- It takes approximately one CFH to elevate the CO2 density in a conventional 10-by-10-by-8-foot space with a normal 350 PPM of CO2 density to a level of 1,500 PPM.
- Smaller, more precisely regulated burners are necessary to maintain the desired levels.
Here are some examples of what our store has to offer: The Gro1 CO2 Regulator costs $99.95, whereas EZ CO2 Homegrown CO2 is $32.95 per kilogram.
Applying CO2 in Your Grow Room
You can supplement carbon dioxide in your garden because there won’t be an abundance of it in your grow room due to the lack of natural sources of the gas. If you’re ready to utilize it, start by purchasing a CO2 meter that can measure the part per million (PPM) content of CO2 in the air in your grow room’s environment. Maintaining CO2 levels between 1200 and 1500 parts per million (PPM) is excellent, but with increasing CO2 levels in the atmosphere, you’ll want to raise your temps. Maintaining temperatures in the mid-’70s (21°C) to low-’80s (26°C) will not yield significant results since your plants require the capacity to take in, digest, and expel whatever they are consuming.
Don’t be shocked if your plants require temperatures between 85 and 95 degrees Fahrenheit (29 and 35 degrees Celsius) in order to adequately assimilate light and nutrients.
A further benefit of lowering the PPM is that it reduces the average-to-maximum temperature range.
How you give your garden CO2 will determine how simple it will be to regulate:
Since CO2 burners may be programmed to refill levels even when they are not in use, all that is required to bring levels down is opening a window, venting the room or turning on a duct fan to draw the air out. In order to be successful when walking around with a CO2 tank, you must keep an eye on your meter and ensure that CO2 is released when the levels are low. If you accidentally spray a bit too much, simply turn on a fan or open a window and you’ll be good. When it comes to CO2 bags, it is important not to squander any CO2.
Using tiny blade fans in the bottom corner of your growing room will ensure that CO2 remains in the air under these circumstances.
Overall, CO2 will result in larger, better-yielding crops, as well as greater yields every year.
Your ppm level should be between 1000 and 1500 by venting your system, and you’ll want to make sure that your water and light levels are always within range of 1000-1500 as well.
[How-to] Increase Cannabis Yields by Adding CO2 to Your Grow Room
Have you ever experimented with increasing the amount of CO2 in your grow room in order to enhance your yields? If this is the case, and you’re wondering why you would want to add more CO2 to your grow room, read on.
Alternatively, how can you increase the amount of CO2 in your growing space? You have arrived to the correct location! We will explore why plants require CO2 and how we might introduce additional CO2 into a grow tent or a grow area while considering the advantages and disadvantages of each method.
Why Do Plants Need Carbon Dioxide (CO2)
Carbon dioxide (CO2) is essential for the growth of plants because it allows them to undertake photosynthesis, which allows them to convert light energy into energy for growth. Plants would perish if CO2 were not present. Fortunately, there is generally always some CO2 floating about in the atmosphere. This gas has no odor and is colorless, and you are most likely breathing in minute amounts of CO2 at this very now. Increasing the amount of carbon dioxide (CO2) in your grow room has a variety of benefits for plants, including improved plant health and development.
- Plants photosynthesize, which is the process by which they transform light energy into nourishment for themselves, when they get additional CO2.
- The presence of these characteristics is frequently demonstrated by thicker roots, larger dark green leaves, and much more blooms as compared to plants that get insufficient CO2.
- By supplying it with additional CO2, the plant is able to utilize more light than it would otherwise be able to.
- PPM (parts per million) is the unit of measurement for CO2 (Parts Per Million).
- If the CO2 concentration in your growing area falls below 200 parts per million (PPM), your plant will cease to grow.
- Plant development has been proven to be enhanced when CO2 levels or concentrations are approximately 1500 PPM, according to several studies.
- Additionally, if you keep your growing space at 1000-1200 PPM of CO2, your plant will be able to handle higher temperatures, which means that if your lights generate a lot of heat, your plant will be able to tolerate it better.
How to Produce A Surplus Of CO2 For A Grow Tent
There are several ways to generate excess CO2, but there are only two strategies that provide a high degree of ease and efficiency at a reasonable cost. CO2 tanks and CO2 generators are examples of these approaches. In terms of increasing CO2 levels, these are the most effective and recommended strategies. Before you begin pumping CO2 into your grow room, you must ensure that the space is entirely sealed to ensure that outside air does not enter and alter the CO2 concentration. It is pointless to spend time and money on CO2 boosters if the air is able to escape from your grow room since it will just escape out of your grow room.
Set up cool tubes or hooded reflectors in your grow room to separate the air from the CO2 to guarantee that you don’t mistakenly vent it out accidently.
We don’t have to worry about our LEDs becoming too hot because the device has built-in fans.
In a cool tube, grow light may be produced. An illustration of how sealing your grow lamp works in order to prevent CO2 from escaping is shown below.
Using A CO2 Tank
This method of creating excess CO2 entails filling tanks with CO2 that has already been saturated. The use of CO2 tanks in carbon dioxide augmentation is a straightforward and cost-effective solution that is a favored first step. In order to be more convenient, the compressed CO2 or CO2 tanks should be situated outside of the grow room and connected to the growth tent by a pump that feeds into the growing area. There must be a safe distance between the pump and the plant. Due to the fact that CO2 is somewhat thicker than oxygen, it will sink to the bottom of your grow chamber.
- Fun fact: The stomata on the surface of plant leaves are responsible for CO2 absorption.
- Essentially, plants contain thousands of microscopic apertures (stomata) that serve as a substitute for their own lungs.
- Despite the fact that the advantages of a CO2 tank exceed the negatives, they do have some drawbacks.
- It’s also crucial to remember that the CO2 created in the atmosphere may be toxic to humans and animals, and that it should not be inhaled in large quantities since it can cause respiratory and health problems.
Using CO2 Generators
It is possible to create sufficient CO2 for indoor cultivation with a CO2 generator, which runs on liquid propane or natural gas and is the second most effective alternative. It is possible that the CO2 generator will be pricey. When employing a CO2 generator in a tiny indoor growing facility, it is critical to keep an eye on the temperature since, in compared to a larger indoor growing facility, the temperature increases moisture rapidly. Advice from the experts: To save money on CO2 generator costs, switch it off approximately an hour before the grow lights in your grow room are turned off.
You might also construct your own CO2 booster.
The difficulty with this technology is that, despite the fact that it is relatively inexpensive, it produces only little amounts of CO2 and produces poor outcomes.
Co2+ is a yield booster that will improve the size of your harvest by up to 50%.
This leads in bigger plants and higher harvests. When put within a Grobo or grow tent, Co2+ steadily distributes CO2 into the air, allowing your plants to benefit from the CO2.
Pros and Cons of Using CO2 Enhancers
Increased yields: It has been demonstrated that increasing the amount of CO2 in your grow area will result in faster-growing plants and higher yields. Who doesn’t want to be rewarded for their efforts with more cannabis? You will be able to produce plants that can handle greater temperatures: This is especially advantageous for individuals who use hot, bright grow lights. Plants can withstand temperatures of up to 30 degrees Celsius when CO2 levels are more than 1200 parts per million (PPM) (86F).
This approach is most successful when used with bright lighting: If you are using grow lights that are not very bright, this method will not be as effective. Since a result, this strategy works best when the plant is exposed to more light than it can consume, as the plant will be able to absorb more light than it would otherwise be able to do. Prohibitively expensive: This approach can be prohibitively expensive, especially if you need to close up your growing area. You’ll also need to purchase CO2 refills, which will add to the overall cost of every grow.
Increasing numbers of growers are choosing to develop their favorite strains indoors (for example, super silver haze) since it is extremely fulfilling to be able to grow cannabis all year long, regardless of where you reside in the globe. Many of these individuals, on the other hand, continue to underestimate the importance of the improved production that elevated CO2 provides. Both the CO2 tank approach and the CO2 generators provide producers with an intriguing new way to take advantage of the astounding and well-documented effects of CO2 on plant development.

Do you have any other questions on how to maximize your yields? Write us below.
Dr. E.R. Myers, a plant scientist, has published a series of articles for HTGSupply in which this article is included. A multi-part series on plant development and liming variables is being presented here, the sixth installment (view other articles in this series). Carbon and ventilation will be discussed this month, and temperature and water will be discussed next month to bring the sequence of limiting variables to a close. As you are aware, the most essential item to consider when evaluating plant development is knowing the variables that restrict growth.
- To develop more effectively, identify your growth limiting issue, which can enhance growth, sometimes drastically, without the need to make any adjustments or do any other actions.
- Increasing the amount of CO in the air Other effects of airflow on plants are discussed in detail in Chapter 23.
- Carbon dioxide augmentation in the indoor environment How much CO2 to put to your grow room is question number five.
- As you may have learned from earlier articles, carbon dioxide (CO2) is required for plants to carry out photosynthesis.
- It is a passive process, which means that the plants can only absorb the CO2 that is present in their immediate surroundings.
- Stomata open and close in reaction to the physiology of the plant as well as to environmental conditions.
Indoor growers should be aware that dust and other particulate matter might block stomata, causing them to close.
Use just enough mist to cause the water to condense on the leaves and flow off.
This should be carried out throughout the vegetative development stage.
Powdery mildew and other fungal diseases can occur as a result of high humidity and misting plants.
I am confident that you are aware that water and electricity do not mix.
LIGHT BULB (e.g., MH Metal Halide or HPS High Pressure Sodium bulbs), since this might cause the bulb to crack or break.
The purpose of these protuberances is to trap air around the plant and produce a microclimate.
In the natural environment, wind is responsible for replenishing this microenvironment on a regular basis.
If the air around the plant is not flowing, the pace of development will be slowed when there is a lack of CO2.
CO2 production is aided by increased airflow.
When adding light airflow to a grow area, CO2 intake will rise, and it is possible that H2O output will increase as well.
Even with a fan, experienced growers are aware that CO2 may be a limiting factor in their operations.
I’ve worked in greenhouses all of my life, and every one of them had some form of ventilation or air exchange with the outdoors.
Because ventilation may provide new CO2, it appears to be a smart idea, and it may well be so.
(Keep an eye out for future posts on pests.) If you are venting to the outdoors, you should always screen the air intake and exhaust to prevent contamination.
This protects the plants from the heat generated by my HID bulb, promotes CO2 production through increased ventilation, and also helps to keep mold spore levels down.
When it comes to airflow, like with any element, it is important to remember that too much of a good thing is not a good thing.
Your plants should quiver in the breeze rather than being blown over.
Increase CO2 and O2 exchange by using a fan to create a mild wind.
The high air flow has caused “wind burn” on the leaves of some plants that have been positioned too close to circulation fans.
Other effects of airflow on plants can be seen.
The wind generates microscopic rips in the stem, which are then mended, resulting in a stronger stem.
The absence of most environmental pressures is beneficial to indoor plants, however the absence of needing to deal with wind stress leads in weak stems.
Mechanical stress may be applied to plants in a variety of ways, including shaking them or using a fan to gently blow on them.
In the natural, having shorter and thicker stems makes the plants more robust, allowing them to better withstand wind damage.
I always use a modest circulation fan on early seedlings to help them grow strong stems and grow faster.
Carbon dioxide replenishment in the indoor environment CO2 is frequently a limiting factor before nutrition.
(See CO2 Systems for further information.) If you need to ventilate your grow room, only do it after your CO2 system is turned off, and be sure to let the plants to soak up the CO2 for a few minutes afterward.
(For further information, see Environmental Controls.) It may be possible to utilize a carbon filter to keep fungus spores and bacteria at bay in bigger spaces, and you may not even need to air the area, resulting in a self-contained high CO2 chamber.
According to the United Nations Environment Programme, normal atmospheric CO2 levels (in the air) range between 300 and 500 parts per million, depending on where you live (urban or rural), with an average of 387 parts per million.
In other words, plants that receive plenty of light and water will develop more quickly when CO2 levels in the atmosphere rise.
To achieve these levels of PPM in your growing area, you should add more CO2 to the growth area; maintaining these levels is simple with a Digital Controller.
Leaving CO2 at the soil level may cause it to flow out of your room, making it unavailable to your plants.
Using a tank and many irrigation hoses, you may have one hose positioned directly above each individual plant for irrigation.
If you only have one hose, you can string it above the plants and poke small holes in the tubing to allow the CO2 to seep out over the entire plant.
An simpler, but LESS EFFICIENT, option is to place a single hose behind a fan and distribute the CO2 throughout the region over which the fan blows, although this is less efficient.
The greater the rate at which CO2 departs the growing region, the less efficient the system will be.
I appreciate the urge to use organic or recycled CO2, and honestly, any increase in CO2 should result in an increase in the pace at which your plants grow in your environment.
If heat is not an issue in your grow area, you might even utilize a gas or kerosene space heater to keep things warm.
The burning of fossil fuels results in the emission of CO2 and water vapor as a result of the combustion process.
View the CO2 Regulator and Tank Combo in action.
A good heater should not generate any residue or carbon monoxide (CO), which is a poisonous gas that should be avoided at all costs.
If you use a fossil fuel heater to add CO2, you should be sure to ventilate the room before entering it for your own safety.
Even though I haven’t tried items like CO2 boost (which is just sugar and yeast combined to make CO2), I assume they will add CO2 to the mix, however I’m not sure how long the CO2 will last once it’s been formed.
You should utilize a CO2 tank with a CO2 regulator and release the appropriate quantity of CO2 into your room at the appropriate time, in my opinion.
How much CO2 should you put in your grow room?
If you raise the amount of CO2 in your room’s environment to 0.2 percent of the total atmosphere, the result is 2000 parts per million (ppm).
Determine the size of your room in order to accomplish this (length x width x height).
Example: If your room is 5 feet by 5 feet and has a height of 8 feet, the volume of the space is 175 cubic feet (5x5x8=175), and 175 x 0.002 = 0.35 You must discharge 0.35 cubic feet of CO2 into the room in order to be successful.
If the flow rate is 10 cubic feet per hour, divide 0.35 by 10 to get 0.035 hours, or (0.035x60min/hour) 2.1 minutes per hour if the flow rate is 60 minutes per hour (two minutes) That is a small amount of CO2 to emit in exchange for a possible doubling of yield.
As you are well aware, providing your plants with excessive CO2 will not result in increased growth.
Carbon dioxide is not hazardous to plants, therefore if you are unable to be accurate, err on the side of caution and overestimate the amount.
Higher amounts of exposure can result in unconsciousness or death within minutes of being exposed to them.
High levels of CO2 for people are greater than 2 percent, but what I am presenting for your plants, a significant increase in yields with CO2 at 0.2 percent, is not even near to that kind of concentration.
SmartBee Controllers are an excellent technique to regulate CO2 levels in the grow room environment.
So go ahead and get that CO2 tank and regulator or CO2 generator, and then shoot me an email at: [email protected] with your questions.
It’s always interesting to learn about your adventures. Thank you for your efforts in growing. Dr. E.R. Myers is a physician who practices in the United States.
How to Add Co2 to Tent Grow
When animals, including humans, breathe, carbon dioxide (CO2) is produced. This is due to the fact that animals take in oxygen and exhale carbon dioxide. In the same way, plants take in CO2 and exhale oxygen, which is necessary for mammals to exist. This cycle is critical in the ecosystem because it demonstrates how plants and animals rely on one another for their own existence. Animals require oxygen to breathe, which comes from plants, whereas plants require carbon dioxide, which comes from animals as a by-product of respiration, to exist.
The present amounts of CO2 in the outside environment may be sufficient for plants that are cultivated outside or in the open atmosphere to live in the current climate.
When animals, including humans, breathe, carbon dioxide (CO2) is generated. For the reason that creatures take in oxygen and exhale carbon dioxide. In the same way, plants take in CO2 and exhale oxygen, which is necessary for animals to thrive in the environment. Plants and animals are interdependent on one another for existence, which makes this cycle critical in the environment. Animals require oxygen to survive, which comes from plants, while plants require carbon dioxide, which comes from animals as a by-product of respiration, to grow and thrive.
Because of the present amounts of CO2 in the outside atmosphere, it is possible that plants planted outside or in an open environment will survive.
Benefits of adding co2
The first and most important point to note is that extra CO2 will dramatically accelerate the growth of your plant. As a result, increased CO2 equals increased energy for photosynthesis to occur. This is because plants require more CO2 to function well, and so require more CO2 to function properly. During the vegetative phase, CO2 is essential. This is due to the fact that more CO2 will accelerate the rate at which your plants stretch, grow large and strong, and that they will do so in a shorter period of time, as opposed to when there is inadequate CO2.
This is due to the fact that it allows flowers to develop more quickly and to become larger in size.
In general, the optimal time to give co2 is during the first 2-3 weeks of flowering, according to the experts. Additionally, the addition of co will enhance the moisture content of your plant, which will aid in its growth.
Methods of adding co2
In the first place, and perhaps most importantly, the injection of co2 will dramatically accelerate the growth of your plant’s root system. As a result, increased CO2 equals greater energy for photosynthesis to occur. This is because plants require more CO2 to function well, and so require more CO2 to function properly. During the vegetative phase, CO2 is critical. Due to the fact that more CO2 will accelerate the rate at which your plants will stretch, grow large and strong, and that they will do so in a shorter period of time, as opposed to when there is not enough CO2.
Due to the fact that it allows flowers to develop more quickly and to become larger, it is beneficial to the environment.
Additionally, the addition of co will enhance the moisture content in your plant, which will aid in its growth and development.
- Co2 tanks that are regulated, co2 banners, natural co2 methods, co2 controllers, and so on
Please keep in mind that the approach that you choose will be highly influenced by the location or the spot where you have placed your plant. Either in a grow tent or a grow room is OK.
For plants that are cultivated in tents, this approach is the most successful, and it comes highly recommended. They are widely used because they are simple and straightforward to construct and install, requiring little or no mechanical or professional qualification as long as the directions in the handbook are followed correctly. It takes just a co2 tank, regulators, co2 controllers, and a gas tube to complete the installation of your whole product and make it ready for use. When employing this type of approach, experts propose using an aluminum 25- or 50-gallon bucket as the container.
- More plants will be able to grow as a result of this.
- As previously said, the regulator is necessary because it allows the gardener to regulate the flow of carbon dioxide from the co2 tank.
- Co2 can be supplied to the plant through the gas tube.
- Another frequent technique of introducing co2 into your facility is through combustion.
- The following pieces of equipment are required for this method: When natural gas is burnt, carbon dioxide (CO2) is produced as a by-product.
Place the banners in the metal box, making sure they are well-arranged with gaps between them and that they are stable so that they do not fall. The metal box was suspended from the ceiling above the canopy of the plant, allowing CO2 to descend to the plants below.
Natural co2 method
Natural co2 may be produced for use in a co2 bag, which generates fungus and pads that are suspended above the canopy of your garden. When they react chemically with the humidity present in the tent, carbon dioxide is released. When compared to other approaches, this procedure is quick, simple, and extremely inexpensive. However, it is not widely utilized or, more accurately, is not highly recommended since it is ineffective due to a scarcity of controllers and regulators. This must be taken into consideration since a lack of regulators may result in excessive CO2, which is hazardous to human health and can be lethal to plants if not addressed.
Co2 controllers are really handy when it comes to increasing the amount of co2 in your plants. This is due to the fact that it prevents the release of an excessive amount of CO2 into the atmosphere, which might be harmful to the plants. Photosynthesis, which occurs throughout the day, necessitates the consumption of Co2. Co2 is released at this period by the controllers, and the release is locked throughout the night, when co2 is not required for photosynthesis to take place. This prevents the waste of co2 and other resources such as money, as co2 is purchased with money that was already spent.
It also keeps track of the entire amount of CO2 present in the tent’s atmosphere as well.
Once the concentration has been exhausted, the controller will activate the co2 device to provide more oxygen.
When employing these methods, make sure that the space is adequately sealed and that there isn’t too much CO2 in the air because it might be dangerous to the plants and even the animals if there is. It is recommended to utilize CO2 detectors or alarms in the event that there is an excessive amount of CO2. This will provide a signal for situation containment, which will help to avoid any harm. In addition, correctly closing the tent allows plants to utilize all of the CO2 released since if there are any gaps, the CO2 would be devoured by the air before it reaches the plants, reducing their efficiency.

How to Use CO2 to Increase Your Cannabis Yields [Guide]
Was it ever brought to your attention that an excessive amount of carbon dioxide (CO2) might be hazardous to your marijuana plants? Or that if your plants don’t get enough CO2, it might be detrimental to them as well? CO2 is a critical component in marijuana cultivation, and it has the ability to aid, hamper, or even prevent the growth of your plant. It’s important to keep many factors in mind when it comes to feeding your plants with more CO2. First and foremost, you must guarantee that your plants get CO2 levels more than 250 parts per million (ppm).
On the other side, if your plants are subjected to dangerously high CO2 levels, they may succumb to their fate.
The process of photosynthesis is completed by the plants as a result of its presence.
CO2 is formed from one carbon atom and two oxygen atoms, as implied by the name and chemical formula.
The addition of CO2 to your grow room, according to several growers, may enhance your production by as much as 20%. In this article, we will teach you how to properly introduce CO2 into your grow room in order to produce a superior end result.
How Do Plants Use CO2?
Stomata are the pores through which your marijuana plants breathe, and they may be found on all marijuana plants. It is through these that the plant is able to take carbon dioxide from the surrounding environment. Photosynthesis is the process through which plants absorb CO2 from the surrounding environment. Algae, particular bacteria, and plants employ this mechanism to capture light energy before converting it into chemical energy for use in their lives. When you cultivate cannabis indoors, your cannabis plants rely on the light emitted by light bulbs rather of natural sunshine to thrive.
- While the oxygen is being re-released into the environment, the plant is using the essential sugars to continue to develop.
- That is, as long as you provide them with sufficient illumination.
- If your plants were to be kept in a room with insufficient CO2, they would eventually suffocate and die.
- If there is already enough CO2 in the atmosphere and you continue to add more, you will not notice an increase in crop output.
- In such situation, increasing the amount of carbon dioxide in the atmosphere is worthwhile since it will result in greater photosynthesis.
- This simple approach should provide you with a boost in growth as well as an increase in the total yield size as a result.
- It is, however, an expensive procedure, and there are a few factors to take into account before making the decision to invest.
Pros and Cons of Using CO2 Systems for Cannabis
Our recommendation is that you avoid using this method unless you are an experienced cultivator. This material is intended for experienced cannabis gardeners who understand how to maintain a healthy cannabis garden and produce high-quality bud. Make certain that you are also familiar with how to:
- Selecting high-quality growth media and fertilizers is essential. Make use of top-of-the-line strain genetics. Consider installing a high-intensity lighting system. Grow in a room that is both sealed and safe
- Diseases and pests should be avoided or treated.
If you match the requirements outlined above, continue reading to understand how CO2 may be used to boost cannabis harvests. However, you should also be aware of the advantages and disadvantages.
You are already aware of and appreciate the advantages, but here’s a refresher:
- Growth that is more rapid Increased Yield: Once you’ve optimized the other limiting elements, such as light exposure, CO2 can deliver a 20 percent or greater increase in your return on investment. It has also been shown to improve the growth rate of plants by a comparable proportion. Security: As long as you properly seal your space, CO2 can give an added layer of protection because no foul-smelling air is being blown out. With a CO2 generator, you may mask the odor of cannabis with ‘natural’ scents that are not detectable by the human nose.
You Can Raise the Temperature in the Grow Room: If you keep the CO2 level between 1200 and 1500 parts per million, you can raise the temperature to up to 95 degrees Fahrenheit.
- Expensive: Adding CO2 to a grow room is a time-consuming and expensive procedure, especially if you’re running a large-scale business. The least expensive techniques of introducing CO2 are also the least efficient. They can, at the at least, demonstrate the possibility of increasing carbon dioxide emissions. On the good side, the majority of the costs are incurred by the startup equipment. You’ll Need Powerful Grow Lights: Using compact fluorescent lights (CFLs) or T5s will not provide appropriate illumination. As an alternative, we propose that you use bright LED lights or that you buy in an MHor HPS system
- You Must Shut the Grow Area: If you are attempting to raise CO2 levels above 1000 parts per million (ppm), you must seal the room. High quantities of carbon dioxide are detrimental to human health
- Thus, you must take action.
If you’re willing to spend the money and aren’t bothered about the drawbacks, then ask yourself the following questions before moving further.
If you answered ‘yes’ to all of them, you can begin adding CO2 to your growing environment:
- Have you maximized the quantity of light your plants can use from the grow lights you already have in place? What makes you certain that you have completely removed all problems from the grow room, including pests and nutrient deficits
- Are you familiar with the methods of growth control that may be used to boost yields? Are you able to maintain the temperature of the grow chamber between 85 and 95 degrees Fahrenheit? During the vegetative stage, are you able to maintain humidity levels at 70%, and at 60% during the blooming stage
Are you prepared to seal your grow room if you can raise the CO2 content in it to 1500 parts per million (ppm).
How to Introduce Additional CO2 to a Garden
There are a plethora of methods for increasing carbon dioxide levels in the garden. Many of them, on the other hand, do not ensure that the ppm will be administered in a regulated manner. Because of this, we propose that money be invested to guarantee that it is done appropriately. If one of these two solutions is prohibitively expensive, you should avoid using any other systems until you can afford a generator or compressed CO2 system.
Carbon dioxide generators, which resemble patio heaters in appearance, generate CO2 by burning natural gas or propane, and they are becoming increasingly popular. Consequently, the exhaust fumes produced are virtually exclusively composed of water vapor and carbon dioxide, as opposed to other gases. In the case of a generator with a single burner, the CO2 produced should be sufficient for an 800 cubic foot grow room. It is possible to program CO2 generators to automatically turn on or off when carbon dioxide levels reach a pre-determined level.
When you burn these gases, though, you generate a lot of heat, which is difficult to control in a tiny grow room.
Consider the following scenario: your grow room is 10 x 10 x 10 ft.
If you are already having difficulty controlling the temperature and humidity in your home, the generator might exacerbate the situation.
Hydroponics stores, as well as home brewing and compressed gas supply stores, should have compressed CO2 tanks available for purchase. Manufacturers create gas, which is collected and compressed into tanks before being released into the environment. This allows you to inject a regulated amount of CO2 into a space without the need to acquire a CO2 generation system. Furthermore, because you are not emitting heat when you release the gas, there are no issues about temperature or humidity. A pressurized CO2 tank is ideal for use in a small grow room setting.
Connect the doser to the tank and turn on the tank’s valve to start the process.
Remember that photosynthesis can only take place while the lights are turned on, therefore set the timer to turn out the lights at night.
Set a timer to begin administering CO2 approximately 60 minutes after the lights are turned on. Then, configure the last dose to be administered 60 minutes before the lights are turned out. You will be able to give your grow room with sufficient CO2 in an inexpensive manner in this manner.
Other Methods of Adding CO2 to Your Grow Room
The use of natural processes to generate carbon dioxide is part of this strategy. Despite the fact that it is a low-cost and relatively simple approach, it frequently results in a bad stench throughout the fermentation phase. Furthermore, it will only have a little impact on CO2 levels.
The composting process emits a minimal quantity of carbon dioxide, but it is unpleasant and unhygienic to be involved in. When you use handmade compost, it might be difficult to determine whether or not you are adding enough CO2. Additionally, there are a variety of pre-made compost systems available, but they are prohibitively expensive. A generator is an investment that should be planned for if money is going to be spent.
These bags generate CO2 with the use of fungus that grow on organic stuff. It is, however, difficult to grow the fungus appropriately, despite the fact that the producers promise that you do not need to do anything. Additionally, in order to dramatically boost the ppm in a tiny grow space, you must use at least four CO2 bags.
Dry ice is composed out of solid and cold carbon dioxide and is used in refrigeration. When it begins to warm up, it begins to release the gas into the atmosphere. Despite the fact that it is a very successful short-term therapy, it is not recommended for long-term usage due to the high cost. Every day, ice must be manually added, and it is difficult to maintain a consistent level of CO2 in the air. Finally, because it must be used immediately, you will have to return to the store on a regular basis to purchase it.
How to Use CO2 in Your Marijuana Garden
CO2 levels in the atmosphere are currently averaging 405 parts per million (ppm). This is the greatest level that has been recorded in over 800,000 years! In 1980, the average level was slightly higher than 330 parts per million (ppm). According to a study conducted by Bugbee et al., plant growth is increased even when CO2 levels reach 10,000 parts per million! While this is fantastic news for cannabis, people should be on the lookout! CO2 levels above 3000 parts per million (ppm) become dangerous, and levels above 5000 parts per million (ppm) are lethal.
A CO2 concentration of between 1200 and 2000 parts per million (ppm) is more than sufficient to produce an increase in yield.
In an ideal situation, the CO2 source would be located above your marijuana plantation.
You can also use fans to circulate the gas throughout the room, ensuring that your entire crop reaps the benefits.
For example, in a plastic greenhouse, CO2 levels can drop to less than 200 parts per million (ppm) within 60 minutes of sunrise!
Your plants will stop growing if the concentration falls below 100 parts per million (ppm).
A grow room with a CO2 concentration of at least 1200 parts per million (ppm) is required.
During these circumstances, you should see an increase in your yields (some growers claim a 50 percent increase). Another advantage is that the time required for fruiting and flowering can be shortened by up to 10 days.
Final Quick Tips on Increasing CO2 Levels in Your Marijuana Garden
- Consider employing air-cooled lights with glass inserts instead of incandescent lights. It is estimated that around 50% of the heat is removed from the lights before they are allowed to enter the room. Additionally, by employing sealed glass, you may limit CO2 loss to virtually zero levels. Please make certain that the relative humidity level is between 40 and 60 percent throughout your visit. It is possible that the stomata of the plant will close if the level falls too low. Dehumidifiers and recirculating air conditioners should be purchased. It is wasteful to utilize exhaust fans that cycle on a regular basis since it wastes CO2. Fans with oscillation are a wise investment since they increase air circulation. A vapor barrier can form on the bottom surface of leaves due to stagnant air, which hinders carbon dioxide absorption by the leaves. Humic and fulvic acid additions should be used since they help to increase the absorption of iron and other nutrients. In high CO2 environments, iron works as a catalyst for the formation of chlorophyll, hence accelerating the process of photosynthesis. Increase the ratio of ammonium to nitrate in your fertilizer to see if you can improve results. When CO2 levels are high, plants do not absorb as much nitrate-nitrogen, but they do so more effectively when nitrogen is in the form of ammonium.
