Once you get your reflector, use ducting to allow air in and out of the sealed grow space, with the grow light & hood in the middle to rain light down over your plants.

Now let’s learn how to use CO2 enrichment right because I’ve seen a lot of misinformation out there, causing many cannabis growers to waste a lot of money on ineffective CO2 methods. I want to help you set it up the right way and enjoy the benefits! After years of research and study by commercial greenhouse growers, we’ve learned exactly what’s needed to get the benefits of extra CO2.
3.5′ x 3.5′ space – 2 x 400W HPS or LED
Simple, effective way to get started
That means in order for CO2 enrichment to be the most effective, you want to maintain levels up to 1500 PPM of CO2 in your grow space with very bright light.
Unfortunately this likely won’t add enough extra CO2 to be make a difference. It’s good to spend time with your plants, in fact I love hanging out in the grow room, but breathing on your plants probably isn’t going to make them grow any faster.
If you’re using smaller lights with lower light levels, you will need less CO2! Learn more about HPS grow lights and LED grow lights
Many air-cooled hoods (like the one pictured here to the right) have the ability to be hooked up to ducting on both ends, which allows these hoods to be used for CO2 enrichment.

There are multiple ways to introduce CO2 to your garden, but most methods do not guarantee controlled ppm (parts per million, used to measure CO2 levels in atmosphere). For this reason, it’s important to invest in a quality CO2 setup. If the systems below are too costly or demanding for your space, you may consider holding off on CO2 supplemented grows until you’re ready to make the jump.
Compressed CO2 tanks can be acquired at hydroponic stores, compressed gas facilities, or even home brewing stores. In this case, the CO2 is produced by the manufacturers and is collected and compressed into tanks that can be then made available for purchase. This allows you to introduce controlled quantities of CO2 into your garden via emitters without having to own a CO2 generator. The benefit of this setup is that without a CO2 generator, you’re no longer producing heat when releasing CO2 into your garden. For this reason, compressed CO2 is ideal for smaller grow spaces.
Plants extract CO2 from the atmosphere via the plant’s stomates, which are the pores that plants “breathe” through. Photosynthesis begins as the plant uses CO2 in combination with light bulbs or light from the sun to produce both sugar and oxygen. The sugar is used by the plant to grow while the oxygen is released back into the atmosphere.
Increasing CO2 levels in your cannabis garden will allow your plants to create more energy – if you provide adequate lighting as well. Again, light is the second requirement to create energy for your plants, meaning you must match your CO2 levels with your lighting. However, before we dive into how this is done, there are a number of other considerations to make before investing in a CO2 system.
Most gardeners have found that when you are producing high-quality light in your garden, a CO2 level of 1,200 to 2,000 ppm will increase the growth of your plant significantly. Additionally, when using CO2 your plants can handle a higher average temperature – around 85-90 degrees Fahrenheit. Be aware that if your CO2 levels are too high for the amount of light or heat generated in the garden, you will see your plants become damaged from excess CO2.
If you have a handle on the above points, you should be ready to try increasing your yields using added CO2.
CO2 generators, which look something like patio heaters, produce carbon dioxide by burning propane or natural gases. They can be set up to automatically power on or off when CO2 levels reach a specific ppm. Natural gas or liquid propane are very easy to acquire, but the burning of these gases produces heat which can be difficult to regulate in small grow spaces. Because of this, CO2 generators are better suited for large grow spaces with equipment for climate control.
- Grow a healthy garden with a quality product
- Prevent and/or treat mold and pest infestations
- Set up a secure, sealed grow space
- Use an adequate high-powered light system
- Utilize quality strain genetics
- Use quality nutrients and growing mediums
CO2 levels in our atmosphere are around 400 ppm. Interestingly, studies show CO2 levels can continually increase plant growth as ppm reach upwards of 10,000. Note that once CO2 is above 3,000 ppm it starts to become dangerous for humans to breathe, and at 5,000 ppm it is considered lethal.
