Cannabis Cultivation &
Its Large Energy
footprint

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 & 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 & 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, & consumer studies & 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 & 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, & 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 & total production costs will rise.

At this point, it's economically & environmentally essential to use less energy & 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, & 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 & induction lights which use magnets to transmit electricity.

3. Evaluating & analyzing energy by installing smart meters to determine where the most energy is being expended.

4. Grow room air filtration scrubs air & removes contaminants. The buildup that settles into dehumidifiers & air conditioning systems makes equipment work harder & requires frequent filter changes. Grow room air scrubbers help prolong HVAC filter life & allow for machinery to run as efficiently as possible.
