The use of Carbon Dioxide in Cultivation Facilities

Carbon Dioxide Supplementation in Cultivation Facilities

There is more to a cannabis cultivation facility than just a greenhouse. While trends in the cannabis space have continued to rapidly grow, the production of indoor controlled cultivation facilities is currently at an all-time high.

When it comes to facilities, overall cultivation licenses are currently among the most competitive to establish in the United States due to the fact that individual states can place restrictions on how many licenses are granted, and how much square footage can be utilized for growing space. For example, Marijuana Network stated, "The state of Florida only issued seven cultivation licenses while New York just extended its limit from five to ten!" 

Of course, building a cultivation facility may not be advised for just anyone. It's expensive, it's complicated, and requires proper maintenance. Yet, with the right construction, personnel, and process, the end results could not be more lucrative. 

What to consider when constructing a cultivation facility?


Troy Dayton states, "Aside from cryptocurrency, there is simply no other industry changing as rapidly or as unevenly as the cannabis sector". Like most large commercial investments, construction is key and its all about the location. When it comes to building a cultivation facility, in order to grow, climate plays a major role. Cultivators need to recognize even the smallest of influences such as sunlight, wind, and previous natural disasters which all could play a disastrous role. 


While licensing applications are critical, zoning laws can vary depending upon the state and it is always recommended to gain the expertise of a general contractor to manage the construction process of any facility. Zoning laws can differentiate by different state regulations and are built to code with all of the components from heating and air conditioning, to ensuring proper CO2 and airflow systems are in place. 

Carbon Dioxide Safety

With so many variables at play when it comes to operating a large cultivation facility, it is no surprise that a vital component of any operation is ensuring the proper amount of CO2 is supplemented, and proper safety precautions are in place.

Growers can gain tremendous significance from using carbon dioxide supplementation specifically around 1200-2000ppm, with the addition of good sunlight, which can create a 20-30% crop growth increase. The overall result of any CO2-facilitated cultivation center is a whole-bodied, high-quality grow space that can process in a much more efficient means, cutting energy costs and increasing overall revenue. 

Tips for Properly Enriching Plants with CO2

  • Have the right light - the rule of thumb: 7500-1000 lumens per sq foot will allow for the full benefits of CO2 enrichment at 1200-1500ppm
  • Seal the space - prevents CO2 from leaking out and can keep your CO2 levels higher
  • Temperature - Watch your plants, many growers recommend between 85F and 95F for CO2 to be the most beneficial
  • AirFlow - For the best results, a fan pointed upwards can keep CO2 circulating and evenly dispersed efficiently over the crop
  • Rest - Your plants don't take in CO2 when the lights are off, so don't waste valuable Carbon Dioxide when the plants are "sleeping". 

CO2 Safety

When we look at the effects of carbon dioxide specifically on crops, the impact can be extraordinary, yet there are also clear safety precautions that need to be in place to protect individuals in the grow space. Contractors or growers specializing in cannabis development, often know the importance and benefits of CO2 in the grow cycle, however, they seldom understand the negative personal effects that CO2 can have on an individual's health. Plants use carbon dioxide in order to gain more energy and with more energy, comes strength and an increase in overall yield.

What indoor growers may not realize is that high levels of CO2 can also be dangerous. Any sealed, closed, indoor space such as an indoor cultivation facility or grow room can not only assist in plant growth, but also can trap dangerous levels of carbon dioxide. These elevated CO2 levels around personnel can lead to severe negative health effects such as dizziness, nausea, and even death.

Much like the effects of carbon dioxide in indoor air quality, the same personal health effects need to be monitored in the grow space. For decades, it was noted that higher CO2 levels generally enhanced cannabis growth and that CO2 levels had little to no impact on human cognition or overall well being. Unfortunately, it took many serious tragedies and studies such as the Lawrence Berkeley National Laboratory study, "Is CO2 an Indoor Pollutant" to prove otherwise.

Both Harvard, and LBNL have stated, "CO2 levels can directly affect the brain, and if you have a grow room with elevated levels of CO2, the best research says you need to minimize the time you spend in it. You also need to consider purchasing a portable CO2 monitor for everyday use".

How to ensure CO2 Safety in Grow Facilities?

An average CO2 monitor typically includes the ability to measure carbon dioxide concentrations alone or also includes additional capabilities for measuring temperature, relative humidity, barometric pressure or particulate matter. One should take note that when using a carbon dioxide monitor or handheld device, you should never place the instrument near any ventilation that could directly interfere with the readings.

After you have spent thousands of dollars perfecting the perfect cultivation grow room facility, only a real-time CO2 monitor can guarantee that your plants are getting the right amount of CO2 and that your employees and team members are protected.

These are just a few of the top carbon dioxide safety monitors, handheld detectors and CO2 sensors for cultivators in the cannabis industry.

CO2 Multi-Sensor System (CM-7000)

The CO2 Multi-Sensor System is designed to detect Carbon Dioxide (CO2) View the CO2 Multi Sensor Systemlevels in the ambient air to protect employees, workers and establishments. The CM-7000 is required in most jurisdictions by code and regulation and features audible/visual alarms, as well as 12 unique sensor configurations with 4 relays to meet OSHA/NIOSH standards and local fire codes in regards to CO2 safety monitoring. The modern, 8" tablet design offers a clean, no-wire set-up for easy installation in any grow space.

With the CM-7000, large-scale cultivation facilities can have peace of mind in ensuring employees are safe, and should an incident occur rely on the CM-7000's ability to trigger an exhaust fan or send an immediate alarm to the fire department or monitoring company. 

GrowFlux CO2 Microclimate Sensor and Access Point

The GrowFlux Microclimate CO2 Sensor can remotely monitor microclimates andView the GrowFlux CO2 Microclimate Sensor CO2 levels, making critical measurements available from anywhere on your smartphone or PC. With the wireless and battery-powered design, the sensor can be placed anywhere among the crop, allowing growers to pinpoint enrichment dead zones and stratification.

View the GrowFlux Access PointThe GrowFlux Microclimate CO2 sensor features a splash-resistant housing with a hydrophobic gas sensing membrane and is suitable for use in greenhouses, cultivation facilities, and indoor farms. Paired with the GrowFlux Access Point, the device enables the user for cloud-based data logging and helps growers collect the right data every time.


Carbon Dioxide (CO2) Handheld Gas Detector

The GasLab Plus CM-501 is a Carbon Dioxide (CO2) handheld gas detector View the CO2 Carbon Dioxide Handheld Detectordesigned to measure carbon dioxide gas concentrations in many agriculture facilities and grow spaces.

Which CO2 Monitor is Right for You?

First, you must consider your application. Are you monitoring air quality levels for CO2 monitoring, or for safety purposes? 

One of the most common phone conversations we receive from customers is the surprise they get in overall benefits from their new CO2 monitor utilized in their grow space or facility. They've found that monitoring CO2 levels can have a direct impact on their crops, overall productivity and turn around time.
