Should I Use CO2 To Improve My Yields? by Nebula Haze |
How I Wasted $747.23 on CO2 For My Marijuana Garden Our newsletter subscribers have recently been writing in with lots of questions about how to increase marijuana yields, and many of you have specifically been asking about how to use CO2 (carbon dioxide) to increase yields.
I want you to know that I've personally wasted a lot of money on ineffective CO2 supplementation methods ($747.23 to be exact) before I understood exactly how CO2 enrichment works.
There are good ways to add CO2... and there are ineffective ways.
Some methods of adding CO2 work great for a small space, but are a terrible choice for a larger one, and vice versa. When I first got started with CO2, I managed to use pretty much all the ineffective ways for my grow space before I found out how to use CO2 the right way.
Today I will share everything I wish I'd known about CO2 when I got started, so that you don't end up wasting money chasing dreams. In this article, you'll learn exactly how you can use CO2 for faster growth and increased marijuana yields.

CO2 is short for "Carbon Dioxide," an odorless gas that's in the air you're breathing right now.
While humans and mammals need oxygen to breathe all the time, plants "breathe" in CO2 (though marijuana and most plants only use CO2 during the day, they actually "breathe" out CO2 at night!).
Plants need CO2 to grow, and in certain cases, you can inject extra CO2 into your grow room during the day to increase the speed of plant growth.
When people are talking about how much CO2 is in the air, they generally measure in "PPM" or "parts per million." The amount of CO2 is approximately 300-400 PPM in regular air (0.03-0.04% of the air is CO2).
How can plants use more CO2 than what's found naturally in the air?
A long time ago, there was a lot more CO2 in the air than there is now. Some scientists believe that this is why many plants can take advantage of more CO2 than what's naturally found in the air.
CO2 enrichment is only effective during the "day" period.
Like all plants, marijuana stops using CO2 during the night (dark period). CO2 is primarily used by the plant as part of photosynthesis (turning light into energy).
Therefore, flooding your grow area with additional CO2 only provides any benefit when the lights are on.
How does CO2 affect marijuana growth?
Vegetative Stage
CO2 is most effective at increasing the speed of vegetative growth, so adding extra CO2 is one way to grow bigger plants in less time during marijuana's vegetative stage of growth.
Flowering Stage Almost all growers seems to agree that you can get increased growth and even bud production by running CO2 during the first 2-3 weeks of flowering.
After flowering is fully underway, many growers believe that CO2 isn't as effective, and it's true that CO2 has not been proven to directly improve bud production beyond the first few weeks of the flowering stage. However, many growers feel from personal experience that running CO2 does directly increase bud production. Some growers recommend that you keep running CO2 all the way until 2 weeks before harvest.
Benefits of Adding Extra CO2
- If you've maxed out the other limiting factors (especially light), CO2 can make your plants grow faster, produce bigger plants, and enhance your yields.
-
Maintaining 1200-1500 PPM of CO2 in the grow area allows growers to keep temperatures much higher than normal
- It can be beneficial for security since you're not venting out hot, potentially smelly air (you must seal off the grow area for CO2 supplementation to be effective)
Disadvantages of Adding Extra CO2
- As far as light intensity is concerned, plants must be receiving about 7500-10000 lumens of light per sq foot for CO2 enrichment to be effective
- Adding extra CO2 won't help if your plants are already suffering from nutrient deficiencies or other plant problems
- In order to keep CO2 near the plants, you must seal up grow area so it's airtight, which can make it harder to manage temperature and humidity
- Can be expensive to inject enough CO2 into your grow area to be effective
- You must keep temperatures between 85°F (30°C) and 95°F (35°C) in order for CO2 enrichment to be effective
-
Every time you check on your plants, you'll be letting out all the CO2
- CO2 is bad for you at high levels, so you need to take precautions to minimize the amount you're breathing
Still Considering CO2?
It's common for growers try to add CO2 to their grow area, without realizing that something else is limiting the growth of their plants.
Learn more about whether supplementing my grow room with CO2 is right for me.
If you are a good candidate, then adding the right amount of CO2 has been shown to increase overall vegetative growth by up to 20%!
If you've maxed out your limiting factors and sealed your grow room, than adding CO2 could be the final piece to take your grow to the next level, providing you with quicker harvests, bigger plants and enhanced yields. If you're considering CO2, ask yourself...
-
Have I maxed out on the amount of light my plants are able to use? (at least 7500-10000 lumens per sq foot, usually only possible with a 600W or 1000W HID light, or a few 400W HID lights close together)
- Have I already eliminated all problems from my grow such as nutrient problems, bugs, etc?
- Have I already mastered (easy and free) growth control methods to increase my yields?
- Am I willing to seal up my grow area so it's airtight?
- Can I maintain temperatures between 85°F (30°C) and 95°F (35
°C) in my grow area?
- Can I keep humidity below 70% in vegetative and 60% in flowering in my sealed room while running CO2? (Remember, if you use a CO2 generator, it will increase the humidity of the air dramatically so you may need to get a dehumidifier)
If the answer is "Yes" to all those questions, than CO2 enrichment may be right for you....
How Can I Add More CO2 To My Grow Room?
There are 7 popular ways of adding CO2 to the air of your grow area...
- CO2 Generator
- Compressed CO2
- Dry ice
- Fermentation
- CO2 Bags
- Compost
- Breathing in Grow Area
Supplementing CO2 is a great choice for those who have maxed out their other options and are willing to spend the money to do CO2 right.
For these growers, supplementing with CO2 can increase the number of crops grown per year and allow them to grow bigger plants.
If you've got a big grow operation, the bigger yields you get each year will pay for the CO2 investment many times over in the long run.
Unless you've got a very tiny grow area, the most effective CO2 enrichment method is to either invest in a CO2 generator
or to buy tanked or bottled CO2, and then combine your enrichment method with a CO2 monitor.
But you don't need to figure this all out on your own! Scroll down to our "Check It Out" section to be guided through the process of buying the right CO2 method for your grow.
Now you don't have to waste $747.23 on ineffective CO2 methods like I did. You are armed with the information to pick the right CO2 enrichment method for your space.

This incredible plant was grown by nagaviper.
Wow! She's so short with so many delicious colas! The strain is a hybrid mix of Mazar x White Rhino
and this is a picture of the plant right before harvest.
How did he do it?
According to nagaviper, his secret is...
A large tent and a 400W HPS, good air flow and organic fert! :)
How can I start my own grow with a 400W HPS?
