Are CO2 bags any Good?

Is A CO2 Bag For A Grow Tent Worth Your Time and Effort?

ExHale CO2 ExHale 365-Self Activated CO2 Bag

It may seem to many that it is ridiculous to even think about adding carbon dioxide (“CO2”) to any plants. As C02 is the main contributor to global warming; this is understandable. C02 though is so vital to plant growth that climate change skeptics have even stated that extra C02 in the environment may actually help make a greener planet. (Per Scientific America, this theory has been mostly debunked; they do though state that C02 does help make plants greener).

The above is being used as an example of why CO2 is beneficial for photosynthesis and how additional Co2 in your grow area is beneficial. It is not meant to argue for or against climate change. C02 though when properly applied, can result in better crops and overall better cannabis yield.

There are numerous ways to add C02, this report though will concentrate on the easiest and also one of the cheapest options for C02 production; the Co2 bag.

Clarification-Grow Bags and other methods for adding CO2 are only to be used in an enclosed, controlled environment, like a grow tent or grow room. A grow tent and grow room are considered by some to be different and sometimes they are thought to be the same. For the purposes of this article grown tents and a grow room are considered the same and will be used interchangeably. Additionally, this article will only briefly mention a few commercial C02 bags. Both of these bags use the natural ingredient mycelium for When mentioning C02 bags in this article I will be referencing these types of bags that use natural ingredients and any specific bag.

Should You Use CO 2 In Your Grow Room?

A short answer to this question is yes. C02 is mandatory for photosynthesis. So, adding extra C02 to your grow room, grow tent, green room, or another controlled growing area will help you increase yields.

How much will co2 increase yield?

Depending upon how well and the means that you apply C02, it has been shown to increase yields up to 30%.

Specifically, How Does Adding C02 Help Your Plants?

Adding C02 to the grow area has been shown to help in the following areas:

  • Maximize The Veg and Flowering Growth Stage-Extra CO2 can help in both the veg and flowering plant growth stages.
  • Plants Grow Quicker-CO2 aids in photosynthesis, which results in your cannabis plants growing quicker.
  • Overall Increased Yield-Per High Times, adding C02 is especially helpful for increasing cannabis crop yields. The reason being is that a cannabis plant is composed of over 90% carbon, hydrogen, and oxygen. A plant’s only source for carbon, hydrogen, and oxygen is air-borne carbon dioxide, which means that adding co2 will be especially beneficial to any cannabis plant.
  • Miscellaneous-Adding C02 can help keep your plants be fresher and also with pest control.

Popular Co2 Enrichment Methods

Other than a Co2 bag, these are the two most popular methods for Co 2 supplementation.

Co2 Enrichment Kit-A CO2 kit will most likely contain a CO2 monitor, Co2 Regulator or controller, and other equipment used for controlling your CO2 Levels. Also, a CO2 tank is most likely used to add the extra carbon dioxide. The advantage of a C02 kit is that it can allow you, with pinpoint accuracy, to get the required CO 2 level. The disadvantage is that they are complicated and expensive to set up. For example with a kit, you will likely need to learn how to properly use the CO2 monitor, CO2 controller AKA-Co2 regulator, and how to fill up or replace the empty CO2 cartridge or tank. Most CO2 kits will even also cost more than an entry-level Led grow light kit. Because of this, a C02 kit is not recommended for a newbie cannabis grower or experienced home growers on a budget.

Co2 Bucket-A C02 bucket is an easy, cheaper, and organic way for adding C02. One problem with a bucket is that as C02 flows downward a bag that can be hung up will work better.

Why Would You Choose a C02 Bag Over Other Methods?

Co2 bags are used in hydroponics, and other closed, controlled environments like a greenhouse, grow tent, grow room, or another enclosed area. They are the perfect choice for a hobbyist gardener who wants to see if adding co2 to their grow room is worthwhile.

In summary, a bag has the following benefits:

  • Installation– They are easy to set up. Some bags require simple steps for activation, and others require no activation at all. In contrast, a C02 kit is complicated to set up as you will need to learn how to install and operate everything from a monitor and controller and the best way to fill up or replace a CO2 tank.
  • Ecologically Friendly– They are made from mycelium, which is a natural and non-toxic way for adding C02.
  • Better Production– You can expect 20 to 30% or more additional yield than without adding co2.
  • Long-Lasting– Most manufacturers claim that they will last up to six months.
  • Cost-Effective– A bag is considerably cheaper than an enrichment kit. Also, CO2 bags do not require any electricity to work. So, over time, you will save quite a lot on your power bills.

Don’t be confused if you see “Mushroom Bag”, “Mushroom Co2 Bag” or something similar. Mycelium is a type fungi As a result, grow bags are also commonly called Mushroom C02 bags.

How Do They Work?

Mycelium, as stated earlier is a natural co2 generator. A C02 bag holds mycelial mass and via ventilation, it provides a  continuous shower of carbon dioxide into your grow area. This means that with a Co2 bag you will not have to deal with expensive CO2 monitors and regulators that cost hundreds of dollars, or the hassle of either buying or refilling cartridges.

Are C02 Bags Safe?

Can a C02 Bag Be Dangerous To Humans?

It is highly likely that you are aware of the dangers of CO2 poisoning. As a result of these real dangers, you might be concerned that using a CO2 bag for additional CO2 might be dangerous. You should not worry though as a bag cannot generate enough co2 to cause any damage. CO2 exposure above 40,000 PPM is considered dangerous for humans. A grow tent should only be from 1,200 to 1,500 PPM. As a result, for even a large home-use grow tent, you would not be able to place enough bags in it to even get close to the 40,000 PPM CO2 level.

Carbon Dioxide Dangers To Plants

Can you have too much co2 in your grow room?

Excess CO2 can be bad for your plants, and at extreme levels, it can kill your plants. You should try to have Carbon Dioxide levels should be around 1200 PPM for cannabis. When you get above that CO2 level you will have the following issues:

  • Photosynthesis ability will be negatively affected; this will result in slower plant growth
  • Dead spots on your leaves
  • Nutrition-Plants will have a harder time taking on needed nutrition

Popular Commercial Co2 Bags

There are several commercial co2 bags to choose from; the most popular and highly rated are the Natural Co2 Bag and Exhale Co2 Bag. With all bags, all that is needed is that all you have to do is simply activate (some do not even require activation it, hang it up, and let it do its job. Both are stated to last for six months and the Exhale bag even guarantees that it will. This article is a general overview of the co2 bag. So, I will specifically review both of these at a later date.

How To Make a C02 Bag-DIY CO2 Bag

As a Co2 bag is made from natural material; you can definitely try to make your own Co2 bag. Co2 bags are relatively cheap, so, buying one is a better use of your time. Also, for simplicity’s sake, I would first buy a Co2 bag before you try to make one on your own. There are several how-to guides on making one that can be found on the internet. So, instead, of trying to reinvent the wheel, I felt it would be best to just give you a few choices below on a DIY CO2 Bag.

Best Practice In Adding To Your Grow Room

  • Is CO2 Enrichment Necessary? This answer may sound strange as I previously mentioned the benefits of adding Co2. Adding c02 though is relatively new and not necessary for an acceptable yield. Adding C02 is easy. It is though one extra thing that you have to worry about when growing indoor plants. So, especially for newbies, you may want to try to successfully grow a few crops first before adding C02 to your plants.
  • How Many Bags Are Needed? The number of bags needed varies with the manufacturer and what type of plants that you are growing. Exhale for example states you should have one bag per four to six plants. And Natural states that one bag per four cubic feet is the standard that you should use. As the size of the plant varies. The one bag per 4 cubic feet method is the most accurate way to measure.
  • Use The KISS Philosophy When Starting Out-First, try the simplest methods for adding C02 first, (I.E., Grow Bucket, and Grow Boxes), before you purchase an expensive grow Co2 Enhancement kit.
  • How are Co2 Levels Measured? CO2 levels are measured by parts per million or PPM. I.E. 300 PPM means they are 300 carbon dioxide parts per million.
  • What C02 PPM Levels Should I try For In MY Grow Room? You should try to set your C02 at around 1,200 to 1,500 PPM. By the way, this is one of the advantages of planting weed in a grow tent is that you are able to fine-tune the growing environment. As an example, with a grow tent you can control the relative humidity, which you cannot do outdoors. Th
  • How Should The Bags Be Placed? First of all, follow the manufacturer’s instructions. Generally, though Co2 naturally travels downward. So, to make sure you get the most out of your bags, you should suspend the bag two to three feet above your plants. First of all, follow the manufacturer’s instructions.

When Should You Add CO2 To Your Plant?

Co2 can be added safely in all areas of plant growth. However, there are certain times when added Co2 is likely will be of more benefit. Below are the recommended procedures for adding C02 to the veg and flowering growth stages.

  • Veg Stage-Co2 enrichment can be used throughout the entire vegging stage, minus the nighttime.
  • Flower Stage– There is a bit of controversy. Some growers and studies state that adding Co2 is only beneficial during the first two weeks of flowering. Other growers though state that adding CO2 to the grow room is helpful through the entire flowering growth stage. The first two weeks is the one that has been proven by scientific studies. As such, I would first start out using C02 for the entire veg stage and then only use CO2 during the first two weeks. Afterward, if you desire, you may want to see if CO2 enrichment during the entire flowering stage is helpful.
  • Should Co2 Be On 24/7? No, Co2 needs to be turned off during nighttime.

Final Thoughts

You’ve most likely guessed that my answer to the question of “Are CO2 bags any good?” is yes. Unlike many items related to growing cannabis, adding C02 to plants has been scientifically proven to help you grow a better yield for your weed crops. Also, you can get a discount-priced, mushroom bag under $30 on Amazon, the cost is not a barrier. So, as a CO2 bag is proven to work, I would definitely try to the excitement with a bag after you’re finished with one or two successfully crops

 

FAQ
