What is CO2 and What Does it Have to Do With Growing Cannabis?
Co2 is a type of gas that’s present in the air, and it does not have any colour nor produce any odour. Cannabis plants, during the process of photosynthesis, take Co2 from the air and expel oxygen. People do the exact opposite when they breathe.
The Co2 in the air contains about 300 – 400 parts per million (ppm), and this is the amount needed for plants to develop correctly. This means that increasing the Co2 in your plants’ air (within certain parameters) can be beneficial for accelerating their metabolic functions, which means much better results.
Why You Should Use Co2 When Growing Cannabis
Enriching the air in your grow room with Co2 can have the following benefits:
- Accelerates metabolic processes in cannabis plants, making for faster growth in general.
- Increases final yield.
- Reduces stress perceived by plants due to environmental issues.
This Co2 technique in indoor grows must be done following certain parameters. The ideal situation is to increase Co2 until it’s at about 1200 ppm and 1500 ppm.
Cautions to Take When Using Co2 in Indoor Grows
- Avoid using Co2 with the lights off.
- You should stop using Co2 during the last two flowering weeks.
- Keep in mind that your plants will most likely require more water and nutrients.
- Keep careful control of your air intake and extraction fan system so they work according to the Co2 being used, or else you’ll be wasting resources and money unnecessarily.
- Keep an eye on your Co2 levels too; if they get too high (over 2000 ppm) it can be toxic for humans.
Types of Co2 Generators in Our Catalogue
We stock various models and methods of adding extra Co2 to your indoor cannabis grow; let’s have a look at a few examples.
- Complete Manored+Bomb+Electroval+Control Co2 Kit: this kit has a disposable pump that works for about 4 – 8 weeks. It’s easy to use – with the help of a timer you can turn the electrovalve on or off, allowing the Co2 into your grow room’s air in 15 minute bursts.
- Co2 LP Pure Factory Burner: this device turns on automatically and has a safety valve with an alarm in case of fire. It produces Co2 in your grow room by burning propane gas.
