The Use of Carbon Dioxide 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 expand the production of indoor, controlled cultivation facilities is currently at an all-time high.

When it comes to these facilities, overall cultivation licenses are currently among the most competitive to source in the United States. The lack of national oversight has necessitated that individual states take on the all-encompassing oversight role.  From permitting through to tax collection, each state must create its own set of rules and regulations for the industry to follow. And while some have begun to replicate models created in previous states this loose network of rulemaking can also lead to a variety of disparate restrictions like limiting the number of grow licenses or the square footage of facilities. 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?

Location

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 it's 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, could all play a disastrous role. 

Another location consideration is the proximity to the intended target audience.  How closely can you build a facility to your distribution points and eventually the intended consumer?  Does local zoning allow for your facility within city limits?  Will you have any transportation concerns or risk violation of DOT regulations as well?

Finding the correct location is just as important for a grow facility as any other local business.

Zoning

While licensing applications are critical, zoning laws can vary depending upon the state and local jurisdiction.  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 and locality.  What is required in two neighboring towns might be completely different? Building your facility to code can become excessively difficult given the crop you are producing.  Local code officials will require additional information and education throughout the process.  Some local zoning requirements to note are set-backs from schools, air purification prior to discharge, power consumption in a certain grid, and even security protocols.   

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 increase yields by using carbon dioxide enrichment specifically between 800-1,500 ppm.  With the addition of quality lighting, soil, irrigation, and supplements can create a 20-30% increased crop yield. The overall result of any CO2 enriched facility is a high-quality grow space that can produce a product more quickly and efficiently, 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 800-1,500ppm
  • Seal the space - prevents CO2 from leaking out and will maintain your CO2 levels 
  • Temperature - many growers recommend between 85F and 95F for CO2 to be the most beneficial
  • AirFlow - For the best results, have your HVAC system pull from the floor level to pull CO2 up off the floor.  Or, direct a fan upwards from floor level to keep CO2 circulating and evenly dispersed and 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". Use a controller with a light sensor embedded.

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. Recent research and studies have uncovered the exact opposite 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 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 fixed carbon dioxide monitor or handheld device, you should never place the instrument near any ventilation that could directly interfere with the device taking and reporting accurate 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)
