The topic of sustainability has grown in importance and priority for both consumers and regulators. From reducing emissions to lowering energy and water consumption, cannabis growing facilities face unique challenges when it comes to designing sustainable operations. Moreover, as the cannabis market grows and usage becomes more accepted, regulatory bodies will continue to increase the number of directives to help ensure the safety and quality of cannabis products.

Non-porous flooring options are impervious in nature, helping to isolate contaminants on the surface, thus enabling proper cleanup and disposal.

Ubiquitous throughout cannabis grow rooms and greenhouses, flooring can be easily overlooked, yet offers an economical way to create more sustainable facilities. Many of today’s grow rooms are located in old retrofitted warehouses or former industrial buildings that were designed without sustainability or environmental concerns in mind.

Combined with energy efficient lighting and more thoughtful water usage, flooring can help create a more efficient facility that not only improves business operations, but also contributes to a better bottom line.

Sustainability Challenges Facing Cannabis Facilities

Whether in an old warehouse space or a new structure designed from the ground up, cannabis businesses face unique operational challenges when it comes to sustainable best practices.

  • Energy Consumption: Like any indoor farm, lighting plays an important role in cannabis growing facilities. Traditional grow lights can utilize a large amount of electricity, putting a strain on the company budget as well as regional energy resources. Switching to highly-efficient LED lighting can help facilities reduce their consumption, while still maximizing crop yield.
  • Water Consumption: Among the thirstiest of flora, cannabis plants require consistent and plentiful watering for healthy and fruitful crop production.
  • Carbon Dioxide (CO2) Enrichment: In many cases, carbon dioxide is introduced into facilities to help enhance the growth of crops. However, this practice may pose safety and health risks for workers, the surrounding community and the planet at large. CO2 is a greenhouse gas known to contribute to climate change.

In order to head off upcoming regulatory restrictions, as well as to alleviate the mounting safety and health concerns, it behooves cannabis grow room managers and owners to explore alternatives for improving sustainability in their facilities.

Flooring Requirements for More Sustainable Cannabis Facilities

Spanning thousands or even hundreds of thousands of square feet throughout a facility, flooring can be a unique way to introduce and support sustainable practices in any grow room or greenhouse.

When seeking to improve operational efficiency and implementing the use of sustainable practices in cannabis facilities, look for flooring systems with the following characteristics:

  • Impervious Surfaces— Fertilizers, fungicides, and other chemicals can infiltrate porous unprotected concrete to leach through the slab matrix and into the soil and groundwater below. Non-porous flooring options, such as industrial-grade, fluid-applied epoxies and urethanes, are impervious in nature, helping to isolate contaminants on the surface, thus enabling proper cleanup and disposal.
  • Light-Reflective Finishes— Light-colored white or pastel floor surfaces in glossy finishes can help reduce the amount of energy needed to properly illuminate grow rooms. By mirroring overhead lighting back upward, bright, light-reflective flooring can help minimize facilities’ reliance on expensive ceiling fixtures and electricity usage.
  • USDA, FDA, EPA, OSHA and ADA Compliancy— With cannabis industry regulations currently in flux, grow facilities that select food- and pharmaceutical-compliant flooring will be ahead of the game. Governing bodies in some states have already begun expanding the facility requirements of these sectors to the cannabis market.
  • Durable and Easy Care— Having to replace flooring every couple of years imposes high costs on businesses as well as the environment. Installation of many traditional types of flooring produces cut-off waste and requires landfill disposal of the old floor material. In contrast, by installing industrial-grade flooring systems that are highly durable and easy-to-maintain, facilities can count on long-term performance and value, while helping to minimize disposal costs and concerns.
Light-colored white or pastel floor surfaces in glossy finishes can help reduce the amount of energy needed to properly illuminate grow rooms.

Optimal flooring can help cultivation facilities reduce waste, improve the efficacy of existing lighting and lengthen floor replacement cycles for a better bottom line and a healthier environment. Additionally, having the right grow room floor can assist facilities in meeting regulatory requirements, help ensure production of quality products and improve the safety for consumers and staff.

Flooring Benefits for Employees and Consumers

Safety is paramount in any workplace. When it comes to the manufacture of foodstuffs and other consumed products, government oversight can be especially stringent. With the right compliant flooring in place, cultivation facilities can focus on the rest of their business, knowing that what’s underfoot is contributing to the safety of employees and their customers.

Here’s how:

  • Chemical Resistance— Floors can be exposed to a high concentration of chemicals, acids and alkalis in the form of fertilizers, soil enhancers and other substances. In processing locations, the proper disinfecting and sanitizing of equipment can require harsh solvents, detergents and chemical solutions, which can drip or spill onto the floor, damaging traditional flooring materials. It pays to select cannabis facility flooring with high chemical resistance to help ensure floors can perform as designed over the long term.
  • Thermal Shock Resistance— Optimal cannabis facility flooring should be capable of withstanding repeated temperature cycling. Slab-on-grade structures in colder climates may be especially vulnerable to floor damage caused by drastic temperature differences between a freezing cold concrete slab and the tropical grow room above. This extreme contrast can cause certain floor materials to crack, delaminate and curl away from the concrete substrate. The resulting crevices and uneven surfaces present trip and fall hazards to employees and leave the slab unprotected from further degradation. As an alternative, thermal shock-resistant floors, such as urethane mortar systems, furnish long-lived functionality even when regularly exposed to extreme temperature swings.
  • Humidity and Moisture Resistance— Traditional floor surfaces tend to break down in ongoing damp, humid environments. Cannabis facility flooring must be capable of withstanding this stress and more.
  • Pathogen Resistance— Undesirable microbes, fungi and bacteria can thrive in the moist, warm environments found in grow rooms. Floors with extensive grout lines and gaps provide additional dark, damp locations for pathogen growth. Fluid-applied flooring results in a virtually seamless surface that’s directly bonded to the concrete. Integral floor-to-wall cove bases can further improve wash down and sanitation.
  • Proper Slope and Drainage— Where food and/or pharmaceutical facility regulations have already been extended to cannabis operations, flooring is required to slope properly toward a floor drain. This prevents puddling, which can be a slip hazard as well as a microbe breeding ground. Unlike more typical materials, resinous flooring offers an economical solution for correcting floor slope wherever needed.

The Problems Presented by Traditional Flooring Options

Previously, cannabis growers often relied on traditional greenhouse-type flooring, including tamped down dirt floors, gravel or bare concrete. However, current and upcoming regulations are curtailing the use of these simple flooring options.

Growers often compare and contrast the benefits and value of traditional greenhouse flooring with more modern solutions, such as fluid-applied epoxy and urethane floors.

Dirt and gravel flooring offers little opportunity to properly sanitize, thus potentially inviting microorganism and pathogen invasion, contamination and costly damage. Growers who have turned to bare concrete floors face other concerns, including:

  • Unprotected concrete is inherently porous and therefore able to quickly absorb spilled liquids and moisture from the air. In addition, organic and synthetic fertilizers, fungicides, and chemicals can leach through the concrete floors, contaminating the groundwater, injuring the surrounding environment and wildlife.
  • Older slabs often lack an under-slab vapor barrier. Even in new construction, a single nail hole can render an under-slab barrier ineffective. In these situations, moisture from underneath the floor slab can move upward osmotically through the alkaline slab, leading to blistering and damage to standard commercial floor coverings.
  • Bare concrete floors can stain easily. These dark stains tend to absorb light instead of reflecting it, contributing to a potential increase in energy usage and cost.
  • The mold proliferation encouraged by the warmth and humidity of grow rooms can easily penetrate into the depths of unprotected slab surfaces, eventually damaging its structural integrity and shortening the usable life of the concrete.

While traditional greenhouse flooring options can initially seem less expensive, they frequently present long-term risks to the health of cannabis grow businesses. In addition, the performance of dirt, gravel and bare concrete floors runs counter to the industry’s commitment to reducing the carbon footprint of growing facilities.

Choosing Sustainable Grow Room Flooring

It’s no secret that the cannabis industry is undergoing enormous change and faces numerous environmental challenges. Luckily, optimal flooring options are now available to help growers economically increase their eco-friendly practices on many fronts. By focusing on quality resinous flooring, cannabis growers can get closer to meeting their sustainability goals, while simultaneously contributing to improved operation efficiency, enhanced yields and an increased bottom line.

The Awakening Green Giant: China and Cannabis

There are many ironies along the path towards global cannabis legalization. Too many to count. But surely one of the oddest was always going to be the reacceptance and relegalization of cannabis in China.

The path so far has been, at a minimum, tortured.

Ritualistic, religious, and medical use of cannabis is mentioned in Chinese texts as early as 3,000 years B.C. and medical literature for the last 2,000 years. Fast forward through Imperial dynasties, the western Age of Empire and exploitation, a cultural and political revolution and two world wars, and it took China until 1985 to actually declare cannabis “illegal.”

Flag_of_the_People's_Republic_of_China.svgDuring the 19th Century British occupation, the majority Muslim Xinjang region of the country was a major cannabis producer (and exporter) to British India.This was done legally and under tariff until 1934 when the communist government cut off legal trade.

Currently,punishment for possession yields10-15 days jail time and a 2,000-yuan (approximately $300) fine. Illegal sales, however, carry the death penalty. Last year, China executed 10 people convicted of drug trafficking in a public space to send a strong statement about the launch of a new anti-drug campaign. It certainly sent a message.

But to Westerners, in particular, a highly confusing one.

So where is the “market?” And how and where is cannabis being slowly reintroduced to the country in the age of global reform?In 2003, they issued regulations to normalize the industry.

Hemp Is Widely Farmed

Farmers in the northerly province of Heilongjiang province, near Russia, are producing hemp legally these days – bound for industrial, medical and edible commercial use. The crop is highly profitable for farmers – bringing in about USD $1,500 per acre.This is far more than other crops like corn. Chinese authorities had, until earlier this century, turned a blind eye to its production. In 2003, they issued regulations to normalize the industry.

This production region also accounts for half of all farmland currently under legal hemp production, globally.

That is not a typo.

More Than Half Of Global Cannabis Patents Are Chinese

During the 20th Century,as cannabis reform moved on, not to mention western medical knowledge expanded about the plant, no surprise, the Chinese government began to lend support to a burgeoning industry and medical research. That also began surprisingly early. During the Chinese involvement in the Vietnam War during the 1970’s, the government needed a source of cheap clothing material for soldiers. They also needed cheap, accessible medicines with strong anti-bacterial properties, particularly in the humid jungle.

Given the highly politicized nature of the plant itself, not to mention current geopolitical developments shaping the global industry, Chinese exports are likely to stir a global conversation.Approximately half of the world’s 600 cannabis patents are now held in China, rivalling the potential of Israel on both the cannabinoid medicine and medical device front.

These days, there is a greater appreciation than ever for “traditional” Chinese medicine,long stigmatized by Western approaches to the same, far from China. The discovery of the so-called “endocannabinoid system” of the body by Israeli scientists at the turn of the century also supports this sea change. Including not only the use of cannabisbut other natural herbs and procedures like acupuncture to stimulate it.

The Chinese domestic medical cannabis trade, in other words, is ready to take off in the world’s largest greying population. The horse has, obviously, left the barn in the West.

But what does all this mean for non-Chinese competitors not only in Chinabut outside of it, as the drug heads for export crop status?

Cannabis Trade Wars Are In The Offing

Given the highly politicized nature of the plant itself, not to mention current geopolitical developments shaping the global industry, Chinese exports are likely to stir a global conversation.

President Donald Trump’s administration, it should be remembered, allowed a British CBD import to enter the U.S. pharmaceutical market this summer (while still banning all U.S. producers from entering the same thanks to delays on rescheduling domestically). It is not an unreasonable prediction to make, certainly after Trump also struck a deal with Israeli President Benjamin Netanyahu to delay the date of Israeli medical cannabis to the rest of the world in exchange for political support in moving the nation’s capital from Tel Aviv to Jerusalem.

A U.S. “ban” on Chinese-sourced cannabis would be one of the most natural responses in the world for the current American administration, which has not only used the cannabis trade card before (Israel, UK) but has yet to move on rescheduling the drug at home.

What To Expect If Considering Importing

Tread carefully. While Europe (at least to North Americans) has its eccentric quirks when it comes to international business, the situation in China is far different.Tread carefully, and find local partners where possible. 

Beyond appalling penalties for getting the paperwork (or etc.) wrong, there aremany differences in business, medical and even broader culture that are completely foreign to Westerners (in particular).

Tread carefully, and find local partners where possible. Where to meet Chinese partners?

Chinese investors are beginning to enter particularly European markets via conferences. In the past several years, while they are still a trickle, Chinese doctors, investorsandscientists have begun appearing in the West. Particularly in more medically oriented forums in Europe.
