The Benefits of Adding CO2 to your Grow Room

When it comes to your plants, the most essential and immediately noticeable advantage is the huge boost in growth that will occur, especially if the potential of your setup has already been realized. Additionally, if CO2 levels can be kept between 1000 and 1200 parts per million (ppm), you will be able to operate your grow room at a more comfortable temperature. Growers are always battling to keep temperatures down and minimize temperature stress on their plants, so this may be quite useful information.

CO2 During Vegetation

Adding CO2 during the vegetative growing stage is the most effective strategy to boost the rate at which your plants stretch, allowing your plant to expand with far more vegetative growth in a significantly shorter period of time.

CO2 During Flowering

The blooming stage is the most critical stage to consider when adding CO2 to your grow environment. When CO2 is introduced into a grow room, especially during the first two to three weeks of blooming, it can greatly increase flower output as well as blossom size.

How to Add CO2 to your Grow Room

Exhale CO2 bags are the most natural and straightforward method of supplying CO2 to your grow environment. The Exhale CO2 bag cultivates carbon dioxide 24 hours a day, seven days a week, without the requirement for refill bottles or the utilization of expensive manufacturing equipment. They function as a result of photosynthesis, which is the mechanism through which plant leaves convert sunlight into carbohydrates. The function of chlorophyll in the chloroplasts of the plant converts sunlight, carbon dioxide, and water into carbohydrates and oxygen for the benefit of the plant.

When plants are able to maximize the process of photosynthesis, the consequence is bigger plants that produce higher yields than when they are not.

During the growing season, this mycelial mass produces carbon dioxide, and the one-way breather patch may continuously release CO2 for up to 6 months.

Because CO2 is heavier than air, it’s important to remember to hang the exhale CO2 bag at the top of the grow chamber in order to spray a shower of CO2 over your plants during the growing process.

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.

  1. Consider the following scenario: you have six plants growing in your dressing and no artificial or natural ventilation is available.
  2. When the CO2 supply is depleted, the plants’ growth will come to an abrupt halt.
  3. To avoid these problems, you’ll need to keep your ppm levels under control by venting your grow.
  4. Fans and ducting will be required for proper ventilation.
  5. 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.
  6. 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.
  7. The increased CO2 you’re providing your plants will accelerate the rate at which your plants will develop.
  8. Increased energy will result in greater temperatures in your growing environment.
  9. 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.

  1. These CO2 sources, on the other hand, do not provide extensive coverage.
  2. The use of these products is advised for smaller grow rooms like as grow tents and closets.
  3. 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.
  4. 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.
  5. 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.
  6. Using them is also somewhat less dangerous than using CO2 generators and burners.
  7. CO2 and water are produced as byproducts of this process (humidity).
  8. Most of the time, these generators are designed to create as little heat as possible while also producing the greatest amount of CO2.
  9. 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.
  10. 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.

CO2: The Do’s and Don’ts (Q&A with Donnie from MyCO2) – Expert Advice

Naturally, each plant has its own set of requirements – do you have any plant-specific recommendations?


The simple answer is no, we do not provide plant-specific advice for any of our products. The explanation for this is a lengthy response. As for CO2, there are four major categories, some of which do not utilize carbon dioxide at all, that may be divided. 1. Plants that are green in color (the green colour comes from the green pigments in chlorophyll molecules) These plants are totally autotrophic in their growth. Autotrophic plants require simply sun energy, carbon dioxide, water, and a few trace minerals in order to survive.

  • 2.
  • They must also consume some nutrients from an autotrophic host plant in order to survive.
  • The mistletoe plant is an example of this type of flowering plant (which is actually considered a fungi now).
  • Insect-eating Plants (Insectivorous Plants) They employ carbon dioxide for photosynthesis, but they still require a little amount of additional energy.
  • Insectivorous plants can survive without capturing animals, but they are much healthier if they can capture a bug every now and then to keep their nutrition levels up.
  • Plants that are holoparasitic They must be attached to an autotrophic host plant in the same way as semiparasitic plants must be connected to a host plant.
  • However, because these plants lack any green components and are unable to photosynthesise, they do not consume carbon dioxide.

Because the great majority of the plants cultivated by our clients are those that absorb CO2 during photosynthesis, we do not provide any plant-specific recommendations or recommendations.

How To Use Co2 In A 2X2 Grow Tent

This is how you determine the quantity of CO2 required to raise the concentration of CO2 in a room from 1200 to 1500 parts per million (ppm): Calculate the volume of the growing area by multiplying the width, length, and height of the growth area together. Calculate the amount of CO2 required to enrich a room to 1200 or 1500 parts per million (ppm) by multiplying the volume of space by 0.0012 or 0.0015.

Can you use CO2 in grow tent?

In the process of photosynthesis, plants utilize CO2, an acronym for carbon dioxide, as a helpful gas to the environment. You can witness significant increases in the pace of growth in your grow tent by adding additional CO2. The fact that many experienced growers are fully aware of this and take use of it is something that they value.

Are exhale CO2 bags any good?

I absolutely like these bags! Increase the consistency of the CO2 levels over the whole growing season Bags can endure for several months, releasing 1000-1500 parts per million of carbon dioxide. I use these CO2 bags in both my clone and vegetable areas, as well as in my flowering areas.

How do you activate an ExHale CO2 bag?

This variant of the Original CO2 Bag, called ExHale 365, is self-activating. Instructions: Take the hanger out of the package. Using a gentle movement, move the spawn pod down to the bottom half of the bag, allowing any material in the higher spawn pod to fall to the sterilised substrate below.

Do plants need CO2 at night?

Photosynthesis is the process by which plants absorb carbon dioxide and emit oxygen during the day, while respiration is the process by which they release about half of the carbon they have taken in.

Does bigger pots mean bigger yield?

When growing in different-sized pots, the larger pot will provide a greater yield. The plant will utilize its two- to three-week stretch to establish roots and determine its maximum size.

Is CO2 in grow tent dangerous?

CO2 concentrations: Beneficial for plant growth, but hazardous for growers. A tightly sealed, closed indoor grow room can trap deadly quantities of carbon dioxide, which can cause serious negative health consequences such as dizziness, unconsciousness, and even death if not ventilated properly.

How long do you use CO2 in flowering?

The blooming stage is the most critical stage to consider when adding CO2 to your grow environment. When CO2 is introduced into a grow room, especially during the first two to three weeks of blooming, it can greatly increase flower output as well as blossom size.

What size humidifier for 2×2 grow tent?

For example, if you have a 22-square-foot grow area that requires around five ounces of moisture each day, the HomeLabs Compact Dehumidifier is an excellent choice. If you require a humidifier for a 44 grow tent and you wish to maintain a relative humidity of 40%, you might consider purchasing a humidifier with a 1-gallon water tank capacity.

When should I stop using CO2 in my grow room?

(27 To 29 degrees Celsius). Because carbon dioxide (CO2) is a crucial component of plant development, plants in surroundings with insufficient CO2 levels – below 200 parts per million (ppm) – would cease to grow and produce. Furthermore, farmers should exercise caution when experimenting with CO2 levels greater than 2000 parts per million (ppm).

What should my CO2 level be in my grow room?

While most scientists think that 1,500 parts per million of CO2 is the optimum amount for optimal plant development, any CO2 level between 1,000 parts per million and 1,500 parts per million will give significantly enhanced outcomes.

How do you keep a 2×2 tent cool?

What you need to do is blow fresh 77-degree air inside the tent to cool down the light. Tape up your light so that no air escapes through it, then blow fresh air from the outside of the tent right through the light and out the other side. It is not necessary to filter it because it is not removing air from the tent.

Does CO2 rise or fall in a grow room?

Indoor grow rooms should, in general, be subjected to a full change of air every fifteen minutes, due to the fact that CO 2 levels might plummet within minutes. Increasing CO 2 concentrations in the grow room to levels greater than the naturally occurring 330ppm throughout the day may unquestionably enhance growth rates and yields by more than 30%.

How do I monitor CO2 in my grow room?

Carbon dioxide (CO2) levels in your grow room should be monitored. Buying an AutoPilot Desktop CO2 Monitor will cost you $119.99. In terms of your grow room, this is a good choice. CO2Meter Mini CO2 Monitor (about $89.00) (at time of writing) It costs $215.89 to purchase a Titan Controls Atlas 5 Portable Handheld Carbon Dioxide Temperature and Humidity Monitor (at time of writing)

How do you cool a tent to grow?

How To Keep A Grow Tent Cool Switch to LED grow lights to save money. Ballasts and drivers should be placed outside the grow tent. Air should be circulated in and out of the tent. In the grow tent, keep an oscillating fan running. Incorporate a Swamp Cooler into your tent. Install a portable air conditioner in the tent. Turn on the lights at night. Relocate the grow to the basement or cellars.

Does CO2 speed up flowering?

Supplementing CO2 for the first two or three weeks of the blooming process becomes one of the more critical time periods for supplementation, as it can help to accelerate the earliest phases of flowering and increase the yield. This will not only expedite the process, but it will also increase the size of the flowers.

Where do you put an ExHale CO2 bag?

Because CO2 is heavier than air, we recommend that you hang the bag one to two feet above your plants, right over the soil. Each bag is supplied with a hanger, but the method by which you attach it is entirely up to you. As soon as your bag is hung from the ceiling, a steady shower of CO2 will fall right onto your plants.

Is too much CO2 bad for plants?

According to the researchers, high CO2 levels lead plants to thicken their leaves, which might exacerbate the consequences of climate change. Researchers in the field of plant science have discovered that as carbon dioxide levels in the atmosphere rise, most plants do something unusual: they thicken their leaves.

How do you cool a small grow room?

Systems for Cooling Grow Rooms Air conditioners are used to cool the air. Air conditioners may be a fantastic alternative for chilling grow rooms; however, you must make sure that you get the correct model for your needs. Fans. A properly installed ventilation system will guarantee that hot air from your grow room is expelled from the space, allowing your plants to remain cool. Dehumidifiers. Water-cooling systems are used.

Does CO2 really increase yield?

Carbon dioxide (CO2) is a gas that exists in our atmosphere and is required by plants in order to complete the process of photosynthesis, in which plants convert CO2 into energy.

High amounts of CO2 in a cannabis garden can result in stronger plants with higher yields — if the CO2 is delivered in the proper manner.

The ExHale Homegrown CO2 Bag’s – do they really work?!

The ExHale CO2 bag has received a lot of bad feedback on the internet forums. Many more encouraging words! Following extensive testing, we discovered that the bags do, in fact, produce a high level of CO2 locally to the bag; however, users must be realistic about the CO2 PPM levels that can be reached when using this product in an enclosed space with ventilation equipment running full time in close vicinity to the bag. Photosynthesis is the process through which plants produce carbohydrates in their leaves.

  1. Plants that are grown inside under artificial light frequently do not have enough CO2 to photosynthesise efficiently.
  2. This new product has received so much attention that we decided it would be a good idea to submit a blog with our honest evaluation of this new product to the internet community.
  3. We have also placed two of the ExHale CO2 bags in our Secret Jardin Dark Room DR300W grow tent in our in-store demonstration, and we have noticed such an improvement in the growth rate of our basil plants that we are now cropping the plants every 1-2 weeks instead of every 2-3 weeks!
  4. Despite the fact that ExHale claims that a bag should last six months, we have discovered that the reduction in CO2 generation means that a bag should be replaced every three months in order to realize the full potential of the product.
  5. Somhydro has given his highest recommendation!

CO2 bags in grow tent – Up or down?

You are currently using an out-of-date web browser. It is possible that this or other websites will not show correctly. You need either upgrade your browser or switch to another one. I recently purchased two CO2 bags for my grow tent, which is equipped with three 600w high-pressure sodium lamps with cool shades or tubes. Temperatures are reaching 30 degrees Celsius, which is said to be ideal for employing CO2 bags. The dilemma is whether to place the bags at a height or on the ground. I’ve mounted them at a high height in conjunction with my lights; is this the proper way to do it?

The reason I ask is that if it isn’t going to make much of a difference, I will switch off the light and the temperature will return to 24-25 degrees.

Nicholas Flamel

I’ve used one previously and couldn’t discern a difference in yield, however the co2 bag should be hung above the plants, which is where you want it. In my understanding, CO2 is a large quantity and will fall upon the plants.


The proper foot is seen above with the fan blowing. However, I’m not certain that it actually does anything. In any case, I’m hoping it will help out in the room and not create any issues; however, I doubt I’ll be able to compare because I typically only run two lights, but now I’m running three, which should result in a few more ounces being extracted. If you’re serious about running CO2, you should consider going to a gas provider and purchasing a 20-pound tank, a regulator, and a metering valve, among other things.

  1. Valve for metering Everyone I’ve ever heard who has utilized co2 bags has stated that they were ineffective.
  2. If you’re only growing a handful of plants, your breath will enough; it’s not until you have 10-20 plants that you’ll need to invest in a CO2 bottle.
  3. He believes it makes a little but significant effect, but not a significant one.
  4. Everyone I’ve ever heard who has utilized co2 bags has stated that they were ineffective.
  5. If you’re only growing a handful of plants, your breath will enough; it’s not until you have 10-20 plants that you’ll need to invest in a CO2 bottle.
  6. The phrase “your breath is plenty” isn’t completely accurate unless you’re camping out in your tent all the time.
  7. I reside in my house, which is directly across the street from where my tent draws in air.

Okay, your tent is sucking in CO2 that you exhale, but this will not result in a big rise in the amount of PPM of CO2 in the tent—certainly not enough to spur growth.

So, certainly, I would say that my breath is sufficient.

A co2 ppm meter or whatever they are called was visible in one of liquid jade’s movies, which I was viewing.

Keep in mind that this was accomplished by a single individual in a respectable-sized grow room over the course of 30 minutes.

Because of this, spending a lot of time with your plants is highly suggested; even simply breathing on them may be beneficial.

They are especially ineffective when there is ventilation since whatever minute quantity of co2 that is produced gets sucked away by the ventilation system.

There is no way they can operate if you have ventilation since any minute quantity of CO2 that they produce gets sucked straight out of the room.

There is a sweet spot for CO2; too much or too little is just as harmful as neither.

That is why I stated that you do not require CO2 adders for tiny growth.

The same is true, of course, for CO2 produced by humans.

Human CO2 would come in and out since it is present throughout the entire room, if not the entire home, and humans are a continual source of supply.

That is, assuming they ever generate anything at all, which, based on all of the other tests I’ve seen run, they don’t.

And what precisely have you witnessed?


I’m not following your point of view.



I don’t use CO2, and I’m smashing yield records with this little strain in this part of the world.

I’m quite confident that wouldn’t happen if I required co2. Clearly, there are many other issues that are more significant than CO2. Co2 is one of those things that you add after you’ve polished everything else in your system.

Can I Use CO2 in My Grow Tent?

One of the most advantageous aspects of indoor cannabis farming is the degree of control you have over the atmosphere. For critical components that plants rely on for development — such as light and CO2 for photosynthesis — this is particularly true. However, while tent growing is incredibly handy due to the simplicity with which it can be set up, the technique provides less versatility in terms of equipment selection than standard growrooms. In general, growrooms can contain more equipment options than tents since they are constructed with solid walls and are capable of being raised up to any desired size.

The use of CO 2enrichment in grow tents is becoming increasingly popular among farmers as a technique of increasing optimal CO 2 levels in the environment.

What is the Benefit of CO 2?

When it comes to proper photosynthesis in cannabis plants, carbon dioxide is a vital component. According to the Ontario Ministry of Agriculture, Food, and Rural Affairs, “photosynthesis is a chemical process in which carbon dioxide and water are converted into sugars in green plants by the action of light energy.” “Through respiration, these sugars are subsequently utilised to fuel the development of the plant inside.” For this reason, maintaining the appropriate amounts of CO 2 in your growroom might be important for producing significant harvests.

Studies have also shown that maintaining CO 2 levels near 1,000 parts per million (ppm) in your growroom can increase photosynthetic rates by as much as 50% compared to gardens that do not have CO 2 enrichment.

Challenges of Using CO 2in a Grow Tent

As has been seen with other types of grow tent equipment, the difficulties associated with utilizing CO2 in these setups are mostly connected to space limits and the fact that they are constructed with fabric walls. Because of this, growers will have a tough time placing CO2 systems within tents when other vital equipment such as grow lights, carbon filters, and inline fans are taken into consideration. Because grow tents are composed of cloth and have zipper doors, there is fear that carbon dioxide (CO 2) may escape before it has a chance to photosynthesise in the tents.

They are able to manage CO 2 levels with remarkable precision since they do not need exhaust systems or intake fans.

CO 2Burners

The combustion of a combustible fuel such as propane allows carbon dioxide to be released into a garden by carbon dioxide burners. When the propane combusts, it releases carbon, hydrogen, and oxygen, resulting in the formation of CO2. CO 2burners are popular among growers largely because propane is more readily available than CO 2tanks.

Importantly, CO 2burners are equipped with atmospheric sensors that provide relay signals to exhaust fans, allowing them to operate more efficiently. As soon as the temperature and humidity in a growroom reach a certain level, the exhaust fan is turned off and the burner is turned on.

CO 2Burners and Tent Growing

Despite the fact that CO 2burners are reasonably simple to use, they are not advised for tent farming. This is mostly due to the fact that these systems operate with an open flame and generate a great volume of heat. Furthermore, the heat generated by CO 2burners will raise the temperature of the interior of the grow tent above the permitted range for cannabis production, creating a potential fire danger.

CO 2Tank and Regulator Systems

A popular source of CO 2 for tank and regulator systems is from tanks that are often used for carbonated beverages. When one of these tanks is used in conjunction with a regulator connected to a CO 2meter, the system automatically enriches your growroom when specified thresholds are reached. These thresholds can include temperature, humidity, and part per million (PPM) amounts of CO2 in the air, depending on your exhaust or HVAC system. CO 2tank and regulator systems are popular among cannabis farmers since they do not need the use of an open flame.

The presence of zippers, portholes, gaps, and minute holes in the fabric walls does not imply that CO 2 is not escaping through these areas.

CO 2Tanks and Tent Growing

Despite the fact that they are safe and logistically possible, CO 2tank and regulator systems might take up important growing space in your grow tent. As a result, due to the limited square footage of tents, these technologies may not be feasible in all configurations. Take a look at these other resources:

CO 2Bags

In the world of indoor gardening, carbon dioxide bags are a relatively new product that has recently entered the market. Manufacturers have created mycelium that emits CO2 as it develops in order to use in these items. This mycelium (the subterranean root-like material produced by mushrooms) may be placed inside a bag and used to enrich CO2 in an organic and cost-effective manner. CO 2bags are an attractive choice for amateur gardeners with modest operations who want to experiment with CO2. Not only are they exceedingly tiny, but they also do not necessitate the acquisition of new equipment, unlike more traditional ways of CO 2enrichment, which do.

CO 2Bags and Tent Growing

If the scale and breadth of your operation allow it, CO 2bags might be a fantastic solution for tent growing operations. They take up very little room, are completely safe to use, and produce no heat at all. Please keep in mind that CO 2bags cannot be used in conjunction with CO 2meters or exhaust relay switches. As a result, they require manual labor to be required for CO2 enrichment in tents, which is expensive. It should be no problem, but, if you have a little home cannabis plant, to physically switch off the exhaust and manually inject CO 2 to your tent using a bag should not be an issue.

Summary: Is it a Good Idea to Use CO 2in My Grow Tent?

While tent cultivation has expanded in popularity over the last several years, we are still learning about the many thresholds that apply to this new sort of growth technique. Growers will continue to push the boundaries of what is feasible in grow tents as their knowledge and experience grows. While it is undeniable that CO 2 enrichment may dramatically increase the yield of cannabis, many people are still debating whether or not utilizing CO 2 in grow tents is a wise investment. If you’re thinking about utilizing CO 2 enrichment in a tent, it’s a good idea to invest in one of the higher-quality types available today.

  • For example, AC Infinity Cloudlab Grow Tents are constructed of the thickest 2000D oxford fabric with an interior light proofing layer and steel poles with a 150 lb.
  • These tents will guarantee that your equipment is protected while also keeping CO2 levels under control.
  • CO 2bags are the most suitable solution for grow tents due to safety issues with tank and regulator systems.
  • AC Infinity is the most recognized name in air delivery systems, having designed and developed the most cutting-edge breakthroughs in cooling and ventilation technology throughout the years.

CO2 Ventilation for the Growing Season ⋆ HTG Supply

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 seep 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 produce 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.
