The Do’s and Don’ts of Adding CO2 to Your Grow Room
February 18, 2022
Plants require carbon dioxide (CO2) to grow, prosper, and propagate. However, when raised in a sealed grow room, plants may struggle to access the amount of CO2 they need to thrive. Using a CO2 regulator and controller setup for plants in your grow room allows you to produce higher yields in less time.
The Best Way of Adding CO2 to Tent Grows
It’s important to remember that while adding CO2 to your tent grow operations has many benefits, growing with CO2 is not a magical fix-all solution. For your CO2 setup to be effective for plants, you must pair it with optimum conditions to promote growth, increasing your plants’ output and raising your overall profits.
DO Calculate the Best CO2 Levels for Your Plants
While the exact approach for calculating the best CO2 levels for plants can depend on your grow system and other variables, there are some consistent factors. Studies have shown that plants achieve optimal growth when CO2 is kept between 1200-1500 PPM (parts per million). Steady levels are most important while the plants are flowering, but plants will benefit at every stage of growth.
DON’T Allow Your CO2 Levels to Drop Too Low
When CO2 levels fall too low in your grow room, plants will struggle to photosynthesize. They will convert all available CO2 and suffocate. The plant's cell structure and overall health will suffer, creating off-color, weak grows.
DO Pair Your CO2 Grow System with Effective Grow Lights
Install the best lighting for your grow system. CO2 is particularly efficient when paired with:
- HPS grow lights
- LEC/CMH grow lights
- Strong LED lights
DON’T Ignore the Temperature in Your Grow Tent
Plants supplemented by a CO2 grow system have a higher resistance to heat than those grown without, and they can stand up to the sometimes high temperatures generated by grow lights. CO2 in tent grow operations is most valuable when the temperature is above 85°F.
How to Add CO2 to Your Grow Room
Once you’ve decided to add CO2 to your grow room, it’s time to decide on how. The best way of adding CO2 to tent grows and keeping levels consistent is through installing a full CO2 setup for plants.
Natural CO2 Methods
Generate natural CO2 by hanging bags that produce fungi or pads from a canopy over your grow room. While this is the cheapest option, it is also the hardest to control and not recommended. CO2 levels are often inconsistent or reach dangerous levels due to the lack of CO2 controllers and regulators.
CO2 Controllers & CO2 Tank Regulators
CO2 controllers and CO2 tank regulators maintain consistent CO2 levels in grow tents. When levels get too high, the regulator switches off until levels get too low, and they power on again. However, for most CO2 controllers to function as designed, someone must be available to switch depleted gas tanks, including on nights, weekends, and holidays.
Automatic Gas Cylinder Changeover Systems
When you want the hands-off experience of a natural CO2 system paired with the safety features and capabilities of CO2 controllers and regulators, an automatic gas cylinder changeover system is your best option. These non-electric auto-switching CO2 setups, such as Assurance Valve’s Eliminator system, feature a variety of advantages, including:
- Straightforward installation
- Higher efficiency than electronic changeover systems
- Lowers waste by using all the CO2 in a cylinder for no loss of product
- Intuitive operational capacities
- And many more!
