The Complete Guide to Co2 Generator for Your Home or Garden


If you want to keep your indoor or outdoor plants healthy, you need to have a reliable and affordable source of carbon dioxide. But finding the right Co2 generator for your home or garden can be tricky and expensive.

Without the right Co2 generator, your plants won’t get the nutrients they need, leaving them wilted, yellow, and unhealthy. That means more money is wasted on replacing dying plants and less oxygen in the air to breathe.

This article is here to save you time and money. This comprehensive guide will help you find the perfect Co2 generator for your home or garden. Start keeping your plants healthy today!

What is a Co2 Generator?

A device that produces carbon dioxide is called a CO2 generator. The main purpose of this device is to enhance plant growth in indoor gardens and greenhouses. The CO2 generated by these devices can be used to supplement the natural CO2 that plants take in through photosynthesis, helping to increase growth rates and crop yields.

There are different types of CO2 generators, but most of them burn a fuel such as propane, natural gas, or biofuel to produce CO2. Some of the more advanced CO2 generators use a chemical reaction to produce CO2, such as baking soda and vinegar.

CO2 generators can be used with other equipment, such as temperature and humidity controllers, to create the optimal growing environment for plants. They are commonly used in indoor gardens and greenhouses, where the levels of CO2 can be low due to the lack of fresh air exchange and are particularly useful for grow operations that use high-intensity lighting systems, which can rapidly deplete the available CO2 in the surrounding air.

Why You Should Buy a Co2 Generator?

There are numerous reasons why you might consider buying a CO2 generator for your indoor garden or greenhouse:

●      Increased growth rates: Plants use CO2 during photosynthesis, and by supplementing the CO2 levels in your indoor garden, you can help increase growth rates and crop yields.

●      Better plant health: CO2 is essential for plant growth, and by providing your plants with an optimal level of CO2, you can help improve their overall health and vitality.

●      Improved energy efficiency: CO2 generators can help reduce the energy needed to heat and cool your indoor garden, as higher CO2 levels can help improve the efficiency of your lighting system.

●      Increased control over your growing environment: With a CO2 generator, you can control the levels of CO2 in your indoor garden, allowing you to create the optimal environment for your plants.

●      Reduced costs: By increasing growth rates and crop yields, CO2 generators can help reduce costs associated with growing plants indoors, such as electricity and fertilizers.

It’s worth noting that when using a CO2 generator, it’s important to monitor the CO2 levels in your grow space to ensure that they remain within safe levels for you and your plants.

Different types of Co2 Generators

Combustion-based CO2 generators

Fuels such as propane, natural gas, or biofuel are used in these generators to create CO2. They are typically easy to operate and can be used for small and large indoor gardens and greenhouses.

Chemical-based CO2 generators

A chemical reaction produces CO2 in these generators, typically using baking soda and vinegar. They are quiet and do not produce any odor, but they can be less efficient than combustion-based generators.

Compressed CO2 cylinder generator:

Using compressed CO2 cylinders as a source of CO2, these generators release CO2 into the growing area. They are easy to use and portable, but they require regular refilling of the cylinder and can be expensive if you need to refill the cylinder frequently.

CO2 Generator with pH control

Water pH is controlled by these generators, and CO2 is released into the water. They can be used in aquaponic systems and indoor hydroponic systems.

What to Look for When Buying a Co2 Generator?


When buying a CO2 generator, you should consider the following factors:

●      Output: The output of a CO2 generator is measured in cubic feet per hour (CFH). Make sure to choose a generator with an output that matches the size of your grow room.

●      Safety features: Look for a generator that has safety features such as overheat protection and low oxygen shut-off.

●      Timer and control options: Some generators come with timers and control options that allow you to control the amount of CO2 released into the grow room.

●      Quality of materials: Look for a generator made from durable materials that can withstand the high temperatures and humidity of a grow room.

●     Brand reputation: Do some research on the brand of the generator you’re considering to see its reliability and effectiveness.

●      Price: CO2 generators come in different price ranges, make sure to get the one that fits your budget but also meets your needs.

Are  Co2 Generators Worth It?

CO2 generators can benefit indoor gardening and agriculture by increasing the amount of CO2 in the grow room, leading to faster plant growth and larger yields. However, whether or not a CO2 generator is worth it depends on your specific situation and needs.

If you have a large grow operation, a CO2 generator can be a cost-effective way to increase yields and improve the overall health of your plants. However, if you only have a small grow setup, the generator cost may not be justified by the potential increase in yields.


Q: How much heat does it produce?

A typical CO2 burner will produce heat of 200,000 to 1,500,000 British Thermal Units (BTUs) per hour. However, industrial-grade burners can produce heat up to 5,000,000 BTUs per hour.

Q: Do CO2 generators expensive to maintain?

The cost of maintaining a CO2 generator can vary depending on the type of generator and the frequency of use.

Some generators require regular cleaning and replacement of parts such as filters and nozzles, which can add to the maintenance costs. However, many generators are designed to be low maintenance and have long-lasting parts that do not require frequent replacement.

Q: Should I use CO2 in my grow room?

Using CO2 in a grow room can provide several benefits for plant growth, such as Increased photosynthesis, Enhanced plant health, and Increased efficiency of other growth-promoting inputs.
