Sustainable Plastic Packaging Options for Your Cannabis Products

By Danielle Antos

A large part of your company’s brand image depends on the packaging that you use for your cannabis product. The product packaging creates a critical first impression in a potential customer’s mind because it is the first thing they see. While the primary function of any cannabis packaging is to contain, protect and identify your products, it is a reflection of your company in the eyes of the consumer.

For all types of businesses across the US, sustainability has become an important component for success. It is increasingly common for companies to include sustainability efforts in their strategic plan. Are you including a sustainability component in your cannabis business’ growth plan? Are your packaging suppliers also taking sustainability seriously? More and more, consumers are eager to purchase cannabis products that are packaged thoughtfully, with the environment in mind. If you are using or thinking about using plastic bottles and closures for your cannabis products, you now have options that are produced from sustainable and/or renewable resources. Incorporating sustainable elements into your cannabis packaging may not only be good for the environment, but it may also be good for your brand.

Consider Alternative Resins

Traditionally, polyethylene produced from fossil fuels (such as oil or natural gas), has been used to manufacture HDPE (high density polyethylene) bottles and closures. However, polyethylene produced from ethanol made from sustainable sources like sugarcane (commonly known as Bioresin) are becoming more common.

Unlike fossil fuel resources which are finite, sustainable resources like sugarcane are renewable – plants can be grown every year. For instance, a benefit of sugarcane is that it captures and fixes carbon dioxide from the atmosphere every growth cycle. As a result, production of ethanol-based polyethylene contributes to the reduction of greenhouse gas emissions when compared to conventional polyethylene made from fossil fuels, while still exhibiting the same chemical and physical properties as conventional polyethylene. Although polyethylene made from sugarcane is not biodegradable, it can be recycled.

Switching to a plastic bottle that is made from ethanol derived from renewable resources is a great way for cannabis companies to take positive climate change action and help reduce their carbon footprint.

For instance, for every one ton of Bioresin used, approximately 3.1 tons of carbon dioxide is captured from the atmosphere on a cradle-to-gate basis. Changing from a petrochemical-derived polyethylene bottle to a bottle using resins made from renewable resources can be as seamless as approving an alternate material – the bottles look the same. Ensure that your plastic bottle manufacturer is using raw materials that pass FDA and ASTM tests. This is one way to help reverse the trend of global warming due to increasing levels of carbon dioxide (CO₂) in our atmosphere.

PET bottles derived from 100% recycled post-consumer material.

Another option is to use bottles manufactured with recycled PET (polyethylene terephthalate). Consisting of resin derived from 100% recycled post-consumer material, it can be used over and over. This is an excellent choice because it helps keep plastic waste to a minimum. Regardless of the resin you select, look for one that is FDA approved for food contact.

Consider Alternative Manufacturing Processes

Flame Treatment Elimination

When talking about plastic bottle manufacturing, an easy solution to saving fossil fuels is eliminating the flame treatment in the manufacturing process. Historically, this process was required to allow some water-based adhesives, inks, and other coatings to bond with HDPE (high density polyethylene) and PP (polypropylene) bottles. Today, pressure-sensitive and shrink labels make this process unnecessary. Opt out and conserve natural gas. For instance, for every 5 million bottles not flamed approximately 3 metric tons of CO₂is eliminated. This is an easy way to reduce the carbon footprint. Ask your cannabis packaging manufacturer if eliminating this process is an option.

Source Reduction (Right-Weighting)

When considering what type and style of bottle you want to use for your cannabis product, keep in mind that the same bottle may be able to be manufactured with less plastic. A bottle with excess plastic may be unnecessary and can result in wasted plastic or added costs. On the other hand, a bottle with too little plastic may be too thin to hold up to filling lines or may deform after product is filled. Why use a bottle that has more plastic than you actually need for your product when a lesser option may be available? This could save you money, avoid problems on your filling lines, and help you save on your bottom line. In addition, this will also help limit the amount of natural resources being used in production.

Convert to Plastic Pallets

If you are purchasing bottles in large quantities and your supplier ships on pallets, consider asking about plastic pallets. Reusable plastic pallets last longer than wood pallets, eliminate pallet moisture and improve safety in handling. They also reduce the use of raw materials in the pallet manufacturing process (natural gas, metal, forests, etc.) aiding in efforts towards Zero Net Deforestation. And, returnable plastic pallets provide savings over the long term.

If You Don’t Know, Ask Your Cannabis Packaging Partner

It is important to find out if your plastic packaging partner offers alternative resins that are produced from renewable sources or recycled plastics. It is also prudent to partner with a company that is concerned about the impact their business has on the planet. Are they committed to sustainability? And, are they eliminating processes that negatively affect their carbon footprint? What services can they provide that help you do your part?

When you opt to use sustainably produced plastic bottles and closures for your cannabis products, you take an important step to help ensure a viable future for the planet. In a competitive market, this can improve the customer’s impression of your brand, increase consumer confidence and help grow your bottom line. Not only will you appeal to the ever-growing number of consumers who are environmentally-conscience, you will rest easy knowing that your company is taking action to ensure a sustainable future.

Environmental Sustainability in Cultivation: Part 3

By Carl Silverberg

No Comments

Part 1 in this series went into a discussion of resource management for cannabis growers. Part 2 presented the idea of land use and conservation. In Part 3 below, we dive into pesticide use and integrated pest management for growers, through an environmental lens.

Rachel Carson’s book Silent Spring in 1962, is often credited with helping launch the environmental movement. Ten years later, VP Edmund Muskie elevated the environment to a major issue in his 1972 Presidential campaign against Richard Nixon. 57 years after Ms. Carson’s book, we’re still having the same problems. Over 13,000 lawsuits have been filed against Monsanto and last month a jury in Alameda County ruled that a couple came down with non-Hodgkin’s lymphoma because of their use of Roundup. The jury awarded them one billion dollars each in punitive damages. Is there a safer alternative?

“Effectively replacing the need for pesticides, we use Integrated Pest Management (IPM) which is a proactive program designed to control the population of undesirable pests with the use of natural predators, a system commonly known as “good bugs (such as ladybugs) fighting bad bugs”, states the website of Mucci Farms, a greenhouse grower. While this applies to cannabis as well, there is one major problem with the crop that isn’t faced by other crops.

While states are moving rapidly to legalize it, the EPA is currently not regulating cannabis. That is in the hands of each state. According to a story in the Denver Post in 2016, “Although pesticides are widely used on crops, their use on cannabis remains problematic and controversial as no safety standards exist.” Keep in mind that it takes a lot more pesticides to keep unwarranted guests off your cannabis plant when it’s outdoors than when it’s in a controlled environment.

We’re accustomed to using endless products under the assumption that a range of governmental acronyms such as NIH, FDA, OSHA, EPA, USDA are protecting us. We don’t even think about looking for their labels because we naturally assume that a product we’re about to ingest has been thoroughly tested, approved and vetted by one of those agencies. But what if it’s not?

Again, cannabis regulation is at the state level and here’s why that’s critical. The budget of the EPA is $6.14 billion while Colorado’s EPA-equivalent agency has a budget of $616 million. According to the federal budget summary, “A major component of our FY 2019 budget request is funding for drinking water and clean water infrastructure as well as for Brownfields and Superfund projects.” In short, federal dollars aren’t going towards pesticide testing and they’re certainly got going towards a product that’s illegal at the federal level. That should make you wonder how effective oversight is at the state level.

What impact does this have on our health and what impact do pesticides have on the environment? A former Dean of Science and Medical School at a major university told me, “Many pesticides are neurotoxins that affect your nervous system and liver. These are drugs. The good news is that they kill insects faster than they kill people.” Quite a sobering thought.

“We have the ability to control what kinds of pesticides we put in our water and how much pesticides we put in our water.”Assuming that he’d be totally supportive of greenhouses, I pushed to see if he agreed. “There’s always a downside with nature. An enclosure helps you monitor access. If you’re growing only one variety, your greenhouse is actually more susceptible to pests because it’s only one variety.” The problem for most growers is that absent some kind of a computer vision system in your greenhouse, usually by the time you realize that you have a problem it’s already taken a toll on your crop.

Following up on the concept of monitoring, I reached out to Dr. Jacques White, the executive director of Long Live the Kings, an organization dedicated to restoring wild salmon in the Pacific Northwest. Obviously, you can’t monitor access to a river, but you certainly can see the effects of fertilizer runoff, chemicals and pesticides into the areas where fish live and eventually, return to spawn.

“Because salmon travel such extraordinary long distances through rivers, streams, estuaries and into oceans they are one of the best health indicators for people. If salmon aren’t doing well, then we should think about whether people should be drinking or using that same water. The salmon population in the area around Puget Sound is not doing well.”

We talked a bit more about pesticides in general and Dr. White summed up the essence of the entire indoor-outdoor farming and pesticides debate succinctly.

“We have the ability to control what kinds of pesticides we put in our water and how much pesticides we put in our water.”

If you extrapolate that thought, the same applies to agriculture. Greenhouse farming, while subject to some problems not endemic to outdoor farming, quite simply puts a lot fewer chemicals in the air we breathe, the water we drink and the food we eat.

The first article of this series discussed resource management for cannabis growers. In this second piece of the series on how indoor farming has a reduced impact on the environment, we’re going to look at land use & conservation. There are really two aspects and we have to be up front and acknowledge that while our focus is on legal cannabis farming, there’s a significant illegal industry which exists and is not subject to any environmental regulation.

“Streams in Mendocino run dry during the marijuana growing season impacting Coho salmon and steelhead trout who lay their eggs in the region’s waterways.” One biologist reported seeing “dead steelhead and Coho on a regular basis in late August and September, usually due to water reduction or elimination from extensive marijuana farming.” The quotes are from an extensive article on cannabis land use by Jessica Owley in the U.C. Davis Law Review.The concept that land will stay in its natural state is a mixture of idealism and reality.

This is going to continue until it’s more profitable to go legit. For this article, we’re going to focus on the legitimate cannabis grower. On the land use side, we usually hear four main reasons for indoor growing: remaining land can stay in its natural state, fewer space usually translates to fewer waste, you conserve land and natural resources when you don’t use fossil fuels, greenhouses can be placed anywhere.

The concept that land will stay in its natural state is a mixture of idealism and reality. Just because someone only has to farm five acres of land instead of one hundred acres doesn’t necessarily mean they’re going to leave the rest in its pristine natural state. Granted the footprint for automated greenhouses is significantly less but the key is what happens to that extra space. Assuming that it will all be preserved in its natural state isn’t realistic. What is realistic is the fact that a developer may not want to build tract houses abutting a commercial greenhouse operation. If they do, likely there’s going to be more land set aside for green space than if a farm was sold outright and a series of new homes were plunked down as if it were a Monopoly board.

Combined with workforce development program funding, urban indoor farming is getting more attractive every day.That’s not the same kind of issue in urban areas where the situation is different. Despite the economic boom of the past ten years, not every neighborhood benefitted. The smart ones took creative approaches. Gotham Greens started in Greenpoint, Brooklyn and has expanded to Chicago as well. “In early 2014, Gotham Greens opened its second greenhouse, located on the rooftop of Whole Foods Market’s flagship Brooklyn store, which was the first ever commercial scale greenhouse integrated into a supermarket.”

Green City Growers in Cleveland’s Central neighborhood is another example. “Situated on a 10-acre inner-city site that was once urban blight, the greenhouse—with 3.25 acres under glass–now serves as a vibrant anchor for the surrounding neighborhood.”

The beauty of greenhouse systems even those without greenhouse software, is they can be built anywhere because the environmental concerns of potentially contaminated soil don’t exist. The federal government as well as state and local governments offer a myriad of financial assistance programs to encourage growers to develop operations in their areas. Combined with workforce development program funding, urban indoor farming is getting more attractive every day.

As for the argument that greenhouses save energy and fossil fuels, I think we can agree that it’s pretty difficult to operate a thousand-acre farm using solar power. To their credit, last year John Deere unveiled a tractor that will allow farmers to run it as a fully autonomous vehicle to groom their fields while laying out and retracting the 1 kilometer long onboard extension cord along the way. It’s a start although I’ll admit to my own problems operating an electric mower without cutting the power cord.

In a 2017 article, Kurt Benke and Bruce Tomkins stated, “Transportation costs can be eliminated due to proximity to the consumer, all-year-round production can be programmed on a demand basis, and plant-growing conditions can be optimized to maximize yield by fine-tuning temperature, humidity, and lighting conditions. Indoor farming in a controlled environment also requires much less water than outdoor farming because there is recycling of gray water and less evaporation.”

The overall trend on fossil fuel reduction was verified this week when the Department of Energy announced that renewables passed coal for the first time in U.S. history. And on the water issue, Ms. Owley had a salient point for cannabis growers. “The federal government will not allow federal irrigation water to be used to grow marijuana anywhere, even in states where cultivation is legal.” That’s not a minor detail and it’s why outdoor farming of cannabis is going to be limited in areas where water resources and water rights are hotly debated.

Environmental Sustainability in Cultivation: Part 1

Core values often get wrapped into buzzwords such as sustainability, locally sourced and organic. In the first part of a series of four articles exploring greenhouses and the environment, we’re going to take a look at indoor vs. outdoor farming in terms of resource management.

Full disclosure; I love the fact that I can eat fresh blueberries in February when my bushes outside are just sticks. Is there a better way to do it than trucking the berries from the farm to a distribution plant to the airport, where they’re flown from the airport to a distribution center, to the grocery store and finally to my kitchen table? That’s a lot of trucking and a lot of energy being wasted for my $3.99 pint of blueberries.The largest generation in the history of the country is demanding more locally grown, sustainable and organic food.

If those same blueberries were grown at a local greenhouse then trucked from the greenhouse directly to the grocery store, that would save diesel fuel and a lot of carbon emissions. People who can only afford to live near a highway, a port or an airport don’t need to ask a pulmonary specialist why their family has a higher rate of COPD than a family who lives on a cul-de-sac in the suburbs.

Fact: 55% of vegetables in the U.S. are grown under cover. The same energy saving principles apply to indoor cannabis and the reasons are consumer driven and producer driven. The largest generation in the history of the country is demanding more locally grown, sustainable and organic food. They want it for themselves and they want it for their kids.

The rapid proliferation of greenhouses over the past ten years is no coincidence. Millennials are forcing changes: organic fruit and vegetables now account for almost 15% of the produce market. A CNN poll last month revealed that 8 of 10 of registered Democrats listed climate change as a “very important” priority for presidential candidates. The issue is not party I.D.; the issue is that a large chunk of Americans are saying they’re worried about the direct and indirect impacts of climate change, such as increased flooding and wildfires.

So how does the consumer side tie into the cannabis industry? Consumers like doing business with companies who share their values. The hard part is balancing consumer values with investor values, which is why many indoor growers are turning to cultivation management platforms to help them satisfy both constituencies. They get the efficiency and they get to show their customers that they are good stewards of their environment. The goal is to catch things before it’s too late to save the plants. If you do that, you save the labor it costs to fix the problem, the labor and the expense of throwing away plants and you reduce pesticide and chemical usage. When that happens, your greenhouse makes more money and shows your customers you care about their values.

The indoor change is happening rapidly because people realize that technology is driving increased revenue while core consumer values are demanding less water waste, fewer pesticides, herbicides and fertilizers.Let’s add some more facts to the indoor-outdoor argument. According to an NCBI study of lettuce growing, “hydroponic lettuce production had an estimated water demand of 20 liters/kg, while conventional lettuce production had an estimated water demand of 250 liters/kg.” Even if the ratio is only 10:1, that’s a huge impact on a precious resource.

Looking at the pesticide issue, people often forget about the direct impact on people who farm. “Rates in the agricultural industry are the highest of any industrial sector and pesticide-related skin conditions represent between 15 and 25% of pesticide illness reports,” a 2016 article in The Journal of Cogent Medicine states. Given the recent reports about the chemicals in Roundup, do we even need to continue the conversation and talk about the effects of fertilizer?

I’ll finish up with a quote from a former grower. “The estimates I saw were in the range of between 25%-40% of produce being lost with outdoor farming while most greenhouse growers operate with a 10% loss ratio.”

The indoor change is happening rapidly because people realize that technology is driving increased revenue while core consumer values are demanding less water waste, fewer pesticides, herbicides and fertilizers. Lastly, most Americans simply have a moral aversion to seeing farms throw away food when so many other people are lined up at food banks.

10 Questions To Ask Before Installing a Remote Monitoring System

By Rob Fusco

No Comments

No matter the size of your cannabis greenhouse operation, keeping your plants alive and healthy requires the best possible growing environment. This means greenhouse managers and personnel must frequently monitor the status of environmental conditions and equipment. The sooner someone discovers extreme temperature fluctuations, rising humidity or equipment failure, the more inventory you can save.

Image 1: Cloud-based remote monitoring system in protective enclosure — Cloud-based remote monitoring system in protective enclosure

That’s why integrating a remote monitoring system into your greenhouse operation can save you time, money and anxiety. Monitoring systems that use cloud-based technology let you see real-time status of all monitored conditions and receive alerts right on your mobile device.

Installing a monitoring system and sensors can be easier than you might think. Here are answers to ten questions to ask before installing a cloud-based monitoring system:

What is required to use a remote monitoring system?

Most remote monitoring systems require an internet or WiFi connection and access to an electrical outlet. Programming is done through a website, so it’s easiest to use a computer for the initial setup. If you don’t have an internet connection at your location, you’ll want to choose a cellular system. Make sure that there’s sufficient signal strength at your site, and check the signal quality in the area before purchasing a cellular device.

2. How do we determine what kind of monitoring system and sensors we need?

A reputable manufacturer will have a well-trained support team that can assess your needs even without a site visit to determine which products are best for your application. If you feel you need them to check out your greenhouse operation,many companies can set up a video conference or FaceTime chat to substitute for being on site.

You will want to provide details about the scope and purpose of your cannabis growing operation. Important factors to discuss include:

Skeletal structure of the greenhouse (metal, plastic, wood, etc.) and the covering material (glass or plastic).
Floor space square footage and height of each of your greenhouses.
Number of greenhouse structures in your operation.
Outdoor climate to determine if you rely more on heating or air conditioning and the level of humidity control needed.
Space dedicated to phases of growth (cloning and propagation, vegetative, flowering) and the microclimates needed for each.
Types of lighting, ventilation and irrigation systems.
Level of technological automation versus manual operation in place.

The monitoring system representative will then determine the type of system that would best serve your operation, the number of base units you will need and the types of sensors required.

The representative should also be able to provide tips on the placement of the sensors you’re purchasing. For example, to ensure thorough air temperature coverage, place sensors throughout the greenhouse, next to the thermostat controlling the room temperature and in the center of the greenhouse out of direct sunlight.

Note that there shouldn’t be a cost for a demo, consultation or assistance throughout the sales process. Be sure to ask if there are any fees or licenses to keep using the monitoring equipment after you purchase it.

3. Are sensors included with the monitoring system?

In most cases, sensors are sold separately. The sensors you select depend upon the conditions you want to monitor and how many you can connect to your base unit. Certainly, temperature is critical, but there are many other factors to deal with as well, such as humidity, CO₂, soil moisture, water pH, power and equipment failure, ventilation and physical security.

For example, humidity has a direct impact on the photosynthesis and transpiration of plants. High humidity can also cause disease and promote the growth of harmful mold, algae and mildew. Sensors can detect changes in humidity levels.

Image 3: Water pH sensor — Water pH sensor

Like any other plant, cannabis needs CO₂to thrive, so it’s a good idea to include a CO₂sensor that will signal to the monitoring device when readings go out of the preset range. There are even sensors that you can place in the soil to measure moisture content to help prevent over- or underwatering, budget water usage costs, promote growth and increase crop yield and quality.

Of course, all the critical systems in your growing facility—from water pumps to irrigation lines to louvers—rely on electrical power. A power outage monitoring sensor detects power failure. It can also monitor equipment for conditions that predict if a problem is looming, such as power fluctuations that occur at specific times.

Ventilation systems not only help control temperature, they also provide fresh air that is critical to plant health. Automated systems include features like vented roofs, side vents and forced fans. Sensors placed on all these systems will send personnel an alert if they stop running or operate outside of preset parameters.

To monitor the physical security of your greenhouses, you can add sensors to entrance doors, windows, supply rooms and equipment sheds. During off hours, when no staff is on duty, you can remain vigilant and be alerted to any unauthorized entry into your facility.

4. Do monitoring systems only work with the manufacturer’s sensors?

Not necessarily. For example, certain monitoring units can connect with most 4-20mA sensors and transmitters regardless of the brand. When selecting sensors, you might have a choice between ones that are designed by the manufacturer to work specifically with the monitoring system or universal components made by a third party. If the components aren’t made by the system manufacturer, you’ll want to find out if they have been tested with the monitor you are choosing and if you need to work with another vendor to purchase the parts.

5. Is a monitoring system easy to set up, or do we need to hire an electrician?

Many monitoring systems are quick and easy to install, and users can often set them up without hiring an outside expert. Look for one that requires only a few simple physical installation steps. For example:

Mount the device to the wall or somewhere secure;
Plug it into an electrical outlet and an internet connection;
Connect the sensors.

You connect the sensors to the base unit’s terminal strip using wire, which is included with many sensors. The range of many wired sensors can be extended up to 2,000 feet away from the base unit by adding wire that can be easily purchased at any home store. It’s a good idea to hire an electrician if you need to run wires through walls or ceilings.

Usually, once you plug in the device and connect the sensors, you then create an account on the manufacturer’s designated website and begin using your device. There should be no fee to create an account and use the site.

If the manufacturer doesn’t offer installation services, ask if they can recommend a local representative in your area who can set up your system. If not, make sure they provide free technical support via phone or email to walk you through the installation and answer any questions you might have about programming and daily usage.

6. Is there a monthly fee to access all the functionality of a monitoring device?

Many web- or cloud-based systems provide free functionality with some limitations. You might have to purchase a premium subscription to unlock features such as text messaging, phone call alerts and unlimited data logging access.

7. Should we get a system that is wired or wireless? Will we need to have a phone line, cable, internet or something else?

Wireless can mean two different things as it relates to monitoring: how the system communicates its data to the outside world and how the sensors communicate with the system.

The most popular systems require an internet or WiFi connection, but if that’s not an option, cellular- and phone-based systems are available.

A hardwired monitoring system connects the sensors to the base device with wires. A wireless system uses built-in radio transmitters to communicate with the base unit. Some monitoring systems can accommodate a combination of hardwired and wireless sensors.

8. Can one system monitor several sensor inputs around the clock?

Once the monitoring system is installed and programmed, it will constantly read the information from the sensors 24/7. Cloud-based systems have data logging capabilities and store limitless amounts of information that you can view from any internet-connected device via a website or app.

If the system detects any sensor readings outside of the preset range, it will send an alarm to all designated personnel. The number of sensors a base unit can monitor varies. Make sure to evaluate your needs and to select one that can accommodate your present situation and future growth.

When a monitoring system identifies a change in status, it immediately sends alerts to people on your contact list. If you don’t want all your personnel to receive notifications at the same time, some devices can be programmed to send alerts in a tiered fashion or on a schedule. Multiple communications methods like phone, email and text provide extra assurance that you’ll get the alert. It’s a good idea to check the number of people the system can reach and if the system automatically cycles through the contact list until someone responds. Some systems allow for flexible scheduling, so that off-duty personnel don’t receive alerts.

9. Do monitoring systems have a back-up power system that will ensure the alarming function still works if the power goes out or if someone disconnects the power?

The safest choice is a cloud-based system that comes with a built-in battery backup that will last for hours in the event of a power failure. Cloud-based units constantly communicate a signal to the cloud to validate its online status. If the communication link is interrupted—for example by a power outage or an employee accidently switching off the unit—the system generates an alarm indicating that the internet connection is lost or that there is a cellular communications problem. Users are alerted about the disruption through phone, text or email. All data collected during this time will be stored in the device and will be uploaded to the cloud when the internet connection is restored.

If you opt for a cloud-based monitoring system, make sure the infrastructure used to create the cloud platform is monitored 24/7 by the manufacturer’s team. Ask if they have multiple backups across the country to ensure the system is never down.

10. What should we expect if we need technical support or repairs to the system?

Purchase your system from a reputable manufacturer that provides a warranty and offers full repair services in the event the product stops working as it should. Also, research to make sure their tech support team is knowledgeable and willing to walk you through any questions you have about your monitoring system. Often, support specialists can diagnose and correct unit setup and programming issues over the phone.

It helps to record your observations regarding the problem, so the tech team can look for trends and circumstances concerning the issue and better diagnose the problem. Ideally, the manufacturer can provide loaner units if your problem requires mailing the device to their facility for repair.

CCC Launches #WhatsInMyWeed Campaign

By Aaron G. Biros

No Comments

“Your tomatoes are organic. What about your weed?” The language on their homepage is clear: Consumers should seek the same high standards in their cannabis just as they do with food.

Earlier in the month, The Cannabis Certification Council (CCC), a nonprofit that promotes organic and fair trade practices in the cannabis industry, announced the launch of their #WhatsInMyWeed campaign. The consumer education initiative is designed to draw parallels between what buying choices people make in food and cannabis.

The consumer-facing idea is to produce videos and ads that make people question the ethics and environmental sustainability of their cannabis, just as they do when purchasing organic, fair trade-certified produce. According to Amy Andrle, owner of L’Eagle Services in Denver and board member with the CCC, the campaign should benefit cannabis companies that produce ethical and sustainable products. “This campaign is long overdue and much needed to alert consumers about the quality of their cannabis and begin to reward producers of organic, fair trade, sustainable and other high quality and integrity products just as they are in other consumer categories,” says Andrle. “We believe the campaign and accompanying website will drive demand and increase transparency in the cannabis industry.”

According to the press release, the website has a listing of cannabis certifications currently available now, information about them and where consumers can find certified products. Companies can sign up for the #WhatsInMyWeed Pledge as well to let consumers know they produce clean products.

Environmental Controls: The Basics

By Vince Sebald

No Comments

The outside environment can vary widely depending on where your facility is located. However, the internal environment around any activity can have an effect on that activity and any personnel performing the activity, whether that’s storage, manufacturing, testing, office work, etc. These effects can, in turn, affect the product of such activities. Environmental control strategies aim to ensure that the environment supports efforts to keep product quality high in a manner that is economical and sensible, regardless of the outside weather conditions.

For this article, let us define the “environment” as characteristics related to the room air in which an activity is performed, setting aside construction and procedural conditions that may also affect the activity. Also, let us leave the issue of managing toxins or potent compounds for another time (as well as lighting, noise, vibration, air flow, differential pressures, etc). The intent here is to focus on the basics: temperature, humidity and a little bit on particulate counts.

Temperature and humidity are key because a non-suitable environment can result in the following problems:

Operator discomfort
Increased operator error
Difficulty in managing products (e.g. powders, capsules, etc)
Particulate generation
Degradation of raw materials
Product contamination
Product degradation
Microbial and mold growth
Excessive static

USP <659> “Packaging and Storage Requirements” identifies room temperature as 20-25°C (68-77 °F) and is often used as a guideline for operations. If gowning is required, the temperature may be reduced to improve operator comfort. This is a good guide for human working areas. For areas that require other specific temperatures (e.g. refrigerated storage for raw materials), the temperature of the area should be set to those requirements.

Humidity can affect activities at the high end by allowing mold growth and at the low end by increasing static. Some products (or packaging materials) are hydroscopic, and will take on water from a humid environment. Working with particular products (e.g. powders) can also drive the requirement for better humidity control, since some powders become difficult to manage in either high or low humidity environments. For human operations without other constraints, a typical range for desirable humidity is in the range of 20 to 70% RH in manufacturing areas, allowing for occasional excursions above. As in the case of temperature, other requirements may dictate a different range.

In a typical work environment, it is often sufficient to control the temperature, while allowing the relative humidity to vary. If the humidity does not exceed the limits for the activity, then this approach is preferred, because controlling humidity adds a level of complexity (and cost) to the air handling. If humidity control is required, it can be managed by adding moisture via various humidification systems, or cooling/reheating air to remove moisture. When very low humidity is required, special equipment such as a desiccant system may be required. It should be noted that although you can save money by not implementing humidity control at the beginning, retrofitting your system for humidity control at a later time can be expensive and require a shutdown of the facility.

Good engineering practice can help prevent issues that may be caused by activities performed in inappropriately controlled environments. The following steps can help manage the process:

Plan your operations throughout your facility, taking into account the requirements for the temperature and humidity in each area and know what activities are most sensitive to the environment. Plans can change, so plan for contingencies whenever possible.
Write down your requirements in a User Requirement Specification (URS) to a level of detail that is sufficient for you to test against once the system is built. This should include specific temperature and RH ranges. You may have additional requirements. Don’t forget to include requirements for instrumentation that will allow you to monitor the temperature and RH of critical areas. This instrumentation should be calibrated.
Solicit and select proposals for work based on the URS that you have generated. The contractor will understand the weather in the area and can ensure that the system can meet your requirements. A good contractor can also further assist with other topics that are not within the scope of this article (particulates, differential pressures, managing heating or humidity generating equipment effects, etc).
Once work is completed, verify correct operation using the calibrated instrumentation provided, and make sure you add periodic calibration of critical equipment, as well as maintenance of your mechanical system(s), to your calibration and maintenance schedules, to keep everything running smoothly.

The main point is if you plan your facility and know your requirements, then you can avoid significant problems down the road as your company grows and activity in various areas increases. Chances are that a typical facility may not meet your particular requirements, and finding that out after you are operational can take away from your vacation time and peace of mind. Consider the environment, its good business!

How to Reduce Mold & Contaminants in Indoor, Greenhouse and Outdoor Grows

Controlling your grow environment doesn’t start when you germinate your first seeds, it starts before you build your grow. There are steps you can take that will have a significant impact on mold growth and contamination, and these will vary based on the grow environment you choose.

Below is a roadmap to where each grow environment stands in terms of mold and contamination risk, and simple steps you can take to mitigate these factors.

Outdoor

The benefits of an outdoor grow are significant – using natural sunlight to grow plants is both inexpensive and environmentally sound. However, it allows the least amount of control and makes plants susceptible to weather conditions and outdoor contaminants including dust, wind, rain and insects. Depending on humidity and precipitation levels, mold can be a big issue as well.

When selecting an outdoor area for a cannabis farm, there are two important factors to consider: location and neighboring farmland. Geographical environments and sub-climates vary and once you have purchased land, you are committed, so be sure to consider these factors prior to purchase.

While arid desert climates have abundant sunlight and long growing seasons, flat, dry lands are subject to dust-storms, flash floods and exceedingly high winds that can damage crops. Conversely, more protected areas often have high humidity and rainfall late in the season, which can create huge issues with bud rot and mold. Neighboring farms also have an impact on your grow, so be sure to find out what they cultivate, what they spray, their harvest schedule and how they run their operation. Large farming equipment kicks up a lot of contaminant-laden dust and can damage crops by displacing insects to your farm if they harvest before you. Pesticide drift is also a major issue as even tiny amounts from a neighbor’s farm can cause your crops to fail testing, depending on what state you are in.

With outdoor grow environments always at the mercy of Mother Nature, any cultivator is wise to control contamination potential on the ground. Cover soil and protect your crop by planting cover crops and laying plastic mulch on as much ground as reasonable. In many cases it makes sense to irrigate uncultivated parts of your farm just to keep dust down.

Greenhouse

Greenhouses are the future of cannabis cultivation. They allow growers to capture the full spectrum and power of the sun while lessening environmental impact and operating expenses, while still being able to precisely control the environment to grow great cannabis. With recent advancements in greenhouse technology such as automated control systems, positive pressure, geothermal heating or cooling and LED supplemental lighting, greenhouses are the future. However, older or economy greenhouses that take in unfiltered air from outside still have a medium amount of mold and contamination risk.

Before building your greenhouse, study the area while taking into account climate, weather conditions and sun exposure. Excessively windy areas can blow in contaminants, and extremely hot climates make cooling the greenhouse interior a challenging and costly endeavor.

There are several simple operational tactics to reduce contaminants in a greenhouse. Add a thrip screen to keep insects out, thoroughly clean pad walls with an oxidizing agent after each cycle, and keep plants at least 10 feet from pad walls. Plan to flip the entire greenhouse at once so that you can clean the greenhouse top to bottom before your next crop. A continuous harvest in your greenhouse allows contaminants to jump from one plant to the next and reduces the ability to control your environment and eliminate problems at the end of a cycle. Lastly, open shade curtains slowly in the morning. This prevents temperature inversion and condensation, which can cause water drops to fall from the ceiling and transfer contaminants onto plants below.

Indoor

An indoor environment offers ultimate control to any grow operation. Cultivators can grow high-quality cannabis with the smallest potential for yeast and mold growth. Unfortunately, indoor environments are extremely expensive, inefficient and environmentally costly.

With indoor grow environments, keeping mold and contaminants at bay comes down to following a regimented plan that keeps all grow aspects clean and in order. To keep your grow environment clean, change HVAC filters multiple times a month. It’s also important to install HEPA filters and UV lights in HVAC systems to further reduce contamination threats. Clearly mark air returns if they are near the ground and keep those areas free of clutter. They are the lungs of your grow. Also, stop using brooms in the grow space. They stir up a lot of contaminants that have settled to the floor. Instead, use HEPA filter backpack vacuums or install a central vacuum system. Set up a “dirty room” for anything messy on a separate HVAC system, and be sure to thoroughly clean pots after every harvest cycle.
