As cannabis continues to become legal throughout the United States, some specialists are suggesting that growers need to make their operations greener.
New Frontier, a data analysis firm, released and highlighted the massive energy footprint left by cannabis cultivation along with methods to make production more energy efficient.
Electricity is the number one expense growers are faced with and it generally meets or exceeds the leasing cost of the growing space per month during production. New Frontier pulled data from cannabis industry businesses, government agencies, and consumer studies and the results are distressing.
Research suggests that cannabis production in the United States is responsible for the same amount of electricity used by 1.7 million homes. The total cost of energy usage in a cannabis operation is priced at $6 billion yearly.
While indoor growing offers a multitude of benefits including,
• An extremely clean and hygienic growing environment.
• Controlled climate prevents issues with mold or dried out plants.
• Multiple harvests can be artificially conceived per year equalling more revenue.
• Indoor growing helps prevent pest infestations.
It also requires a large amount of electricity. Aside from artificial lighting, indoor growing facilities require dehumidifiers, ventilation, and air conditioning systems. What the report is saying, is that it will be unsustainable to attempt to maintain the cost structure that is driven by such high energy usage.
As of now, energy costs are equal to 1/2 of the wholesale prices of marijuana. As wholesale prices fall, energy and total production costs will rise.
At this point, it's economically and environmentally essential to use less energy and there are ways to make it happen!
1. Growers can move production outdoors or into greenhouses. However, it's important to note that this depends on environmental conditions, local laws prohibiting outdoor growing, and the risks of using pesticides to protect outdoor marijuana.
2. Installing energy efficient light bulbs. Instead of relying on high-intensity discharge lamps switch to uniquely designed LED lights and induction lights which use magnets to transmit electricity.
3. Evaluating and analyzing energy by installing smart meters to determine where the most energy is being expended.
4. Grow room air filtration scrubs air and removes contaminants. The buildup that settles into dehumidifiers and air conditioning systems makes equipment work harder and requires frequent filter changes. Grow room air scrubbers help prolong HVAC filter life and allow for machinery to run as efficiently as possible.

|Room Measurements (feet)|
To clean Square Feet, you will need:
A CleanLeaf media air cleaner is considered an "ambient air cleaning system" designed to run ambient shop air through a series of high efficiency filters and/or carbon depending on the application. When sized for 8-10 air changes per hour, you will create a constant reduction in the amount of airborne particulate in the room between 70-90%. We always recommend capturing the particulate at the source when possible but understand source capture is not always an option. Blue Ox air cleaners are often used as a secondary filtration system to source capture or when source capture is not applicable.
1. First, we determined the air changes per hour requirement from the following:
2. Second, we determined the required CFM for your application:
Sq Footage = Length x Width x Height (We use 12' by default)
Total Required CFM = Sq Feet x 8 Air Changes per hour / 60
3. Determine the total number of units required:
Total Units = Total Required CFM / Unit CF Rating
For Example: 12,000 Required CFM would require (4) 3,000 CFM units
