Regardless of whether your grow is indoor or in a greenhouse, mold is a factor that all cultivators must consider.
After weeks of careful tending, pruning and watering to encourage a strong harvest, all cultivators are looking to sell their crop for the highest market value. A high mold presence, measured through a total yeast and mold count (TYMC), can cause a change of plans by decreasing crop value. But it doesn’t have to.
There are simple steps that any cultivator can take that will greatly eliminate the risk of mold in a grow. Below are some basic best practices to incorporate into your operation to reduce contaminants and mold growth:
Isolate dirty tasks. If you are cleaning pots, filling pots or scrubbing trimming scissors, keep these and other dirty tasks away from grow and process areas. Dirty tasks can contaminate the grow area and encourage mold growth. Set up a “dirty room” that does not share heating, ventilation and air conditioning with clean areas.
Compartmentalize the grow space. Mold can launch spores at speeds up to 55 miles per hour up to eight feet away without any air current. For this reason, if mold growth begins, it can become a huge problem very quickly. Isolate or remove a problem as soon as it is discovered- better to toss a plant than to risk your crop.
No drinks or food allowed. Any drinks or food, with the exception of water, are completely off limits in a grow space. If one of your employees drops a soda on the ground, the sugars in the soda provide food for mold and yeast to grow. You’d be surprised how much damage a capful of soda or the crust of a sandwich can do.
Empty all trash daily. Limiting contaminants in turn limits the potential for issues. This is an easy way to keep your grow clean and sterile.
Axe the brooms. While a broom may seem like the perfect way to clean the floor, it is one of the fastest ways to stir up dirt, dust, spores and contaminants, and spread them everywhere. Replace your brooms with hepa filter backpack vacuums, but be sure that they are always emptied outside at the end of the work day.
No standing water or high humidity. Mold needs water to grow, therefore standing water or high humidity levels gives mold the sustenance to sporulate. Pests also proliferate with water. Remove standing water and keep the humidity level as low as possible without detriment to your plants.
Require coveralls for all employees. Your employee may love his favorite jean jacket, but the odds are that it hasn’t been cleaned in months and is covered with mold spores. Clean clothing for your staff is a must. Provide coveralls that are washed at least once a week if not daily.
Keep things clean. A clean and organized grow area will have a huge impact on mold growth. Clean pots with oxidate, mop floors with oxidate every week, keep the areas in front of air returns clean and clutter-free, and clean floor drains regularly. The entire grow and everything in it should be scrubbed top to bottom after each harvest.
Keep it cool. Keep curing areas cool and storage areas cold where possible. The ideal temperature for a curing area is roughly 60 degrees and under 32 degrees for a storage area. Just like food, the lower the temperature, the better it keeps. High temperature increases all molecular and biological activity, which causes things to deteriorate faster than at cooler temperatures. However, curing temperature is a function of water activity more than anything.
Be Careful With Beneficials. Beneficial insects certainly have their place in the grow environment. However, if you have a problem with mold on only a small percentage of plants, any insect can act as a carrier for spores and exacerbate the problem. By the same token, pests spread mold more effectively than beneficials because they produce rapidly, where beneficials die if there aren’t pests for them to eat. It is best to use beneficials early in the cycle and only when necessary.
Last week at the MJBizCon, a major cannabis industry event held annually in Las Vegas, urban-gro launched the first technology line for cannabis growers utilizing Internet-of-Things (IoT). urban-gro, a cultivation technology company for commercial-scale growers, announced the launch of announced Soleil® Technologies, an integrated portfolio of hardware, software, and services that uses IoT.
“The solution suite includes per-plant sensing, environmental monitoring, machine diagnostics, fertigation management, lighting controls, inventory management, and seed-to-sale tracking,” reads the press release. IoT is essentially a network of devices embedded with sensors and software that allow the devices to connect and exchange data. IoT devices are used extensively in the food industry, including for integrated pest management, restaurant food safety and management and tracking product conditions such as temperature and humidity throughout the supply chain, among other uses.
Soleil consists of three primary lines:
Soleil 360 is the cloud-based software-as-a-service (SASS) platform that integrates all Soleil solutions.
Soleil Sense is the brand for all of urban-gro’s low-power wireless sensors that deliver data with the scale, precision and resolution needed for analytics and machine learning.
Soleil Controls is urban-gro’s product set for climate and irrigation controls, lighting systems, and other focused controls.
The core, low-power sensor that makes this unique was licensed from Edyza, a wireless innovator that specializes in low-power wireless grids that scale. urban-gro then developed on top of that sensor, including its cloud-based management, analytics, what the sensors detect and cover, etc., to make it ideal for cannabis growers.
According to Brad Nattrass, urban-gro’s chief executive officer, finding an IoT solution that can easily scale was a key goal for their business. “When evaluating the most advanced market-ready sensor technology available, it was crucial that we deliver a solution that can easily scale to thousands of sensors in order to satisfy the needs of large-scale commercial cultivators,” says Nattrass. “The introduction of Soleil demonstrates urban-gro’s commitment to going beyond simply supplying equipment, to truly serving our clients as an ongoing technological innovator and advisor, enabling cultivators to leverage today’s more advanced technologies to rise above the competition.”
“Cultivators will be able to monitor substrate moisture and EC (electrical conductivity) levels on a per plant basis, as well as track key environmental metrics like temperature, humidity, air movement, and probability of infestation,” reads the press release. “With multiple device options, cultivators can choose between several deployment options.” With the data hosted on the cloud, users can access it through web browsers, Android and iOS devices.
According to Jay Nichols, a representative of urban-gro, they have hired (and is hiring) code developers, product developers, etc. in order to expand this unit. Plant sensors are just one piece of the system, with the goal to automate the entire cultivation process, including controlling lights, pest management, irrigation and fertigation. They say it will be available in late Q1/early Q2.
Maintaining an environment that supports cultivation and keeps plants healthy is not an easy task. In cannabis growing, there are a variety of factors that greenhouse managers and personnel must monitor to ensure that their plants are in a healthy environment that fosters growth and development. Temperature, humidity, lighting and CO2 levels are a few of the conditions that need to be tailored to each cannabis greenhouse operation. However, it can be difficult to constantly monitor the status of your equipment and the greenhouse environment, especially after hours or during the off-season.
A remote monitoring system that’s properly selected and installed can help greenhouse managers keep their cannabis plants healthy, multiply their yields and increase return on investment. This type of system also helps operators identify patterns and trends in environmental conditions and get insight into larger issues that can prevent problems before they arise.
Here are some tips on key conditions to monitor and what you need to consider when selecting a monitoring system for your cannabis greenhouse operation:
Temperature plays a crucial role in any cannabis grow operation. The climate in your greenhouse must be warm enough to nurture photosynthesis and the growth of cannabis plants. Setting the incorrect temperature will significantly impact the potential yield of the plant and the rate at which it develops. A temperature too low will slow the growth of the cannabis, but too hot can lead to heat stress for your plants. The ideal temperature for a standard greenhouse is between 70 and 80 degrees Fahrenheit. However, depending on the stage of plant and desired growth densities, the temperature of the greenhouse needs to be adjusted accordingly.
Humidity directly affects plant photosynthesis and transpiration, so controlling humidity is vital in greenhouse growing. The ideal relative humidity (RH) for cannabis growth is around 60%. A low humidity level can cause water to evaporate too quickly for photosynthesis, while a humidity level that is too high can cause poor growth and possible mold and fungal disease. Monitoring the moisture content in the air of your greenhouse will help the plants during the transpiration process, increasing absorption of nutrients and overall health of the cannabis.
Your cannabis may be getting an abundance of natural light during the summer months, but maintaining adequate sunlight during the winter months can be a challenge. As a solution to this, many greenhouse managers equip their facilities with additional lights to supplement natural light during off-seasons or off-hours. To achieve the best possible yield, a cannabis plant in the budding stage should receive twelve hours of light each day, while other stages could require additional lighting. For example, the growth stage could require your cannabis to be exposed to sunlight for up to eighteen hours a day.
Like any other plant, cannabis requires CO2 to breathe. Greenhouse managers must set and monitor the CO2 levels in their facility to make sure that there is an adequate amount for the plants to develop, grow and be healthy. The amount of carbon dioxide required for your cannabis depends of the size of the facility and the amount of light the plants are receiving. However, a standard grow area for cannabis can maintain a CO2 range from 1000 to 1500 parts per million (PPM). A level below that threshold can result in slower growth of the plants, while a level above would lead to unused and wasted CO2.
Irrigation and Soil Moisture
One way to ensure a good yield from your cannabis is to water it regularly and monitor your soil moisture. Overwatering your plants can have the same effect, if not worse, than letting the soil become too dry. Plants’ roots need oxygen to survive, unlike leaves that breathe CO2, and when the soil is waterlogged the roots can’t provide their function. The lack of oxygen interferes with the roots’ nutrient uptake and photosynthesis causing the cannabis plant to wilt. The exact moisture content of the soil depends on the size of your greenhouse, temperature and humidity. Whether you hand water or are using a drip irrigation system, being aware of your soil moisture is vital to the long-term health of your cannabis.
Your greenhouse environment should mimic the ideal conditions in which cannabis plants flourish. With an indoor facility, you have the ability to control air circulation by venting hot air out and blowing fresh air in. Creating a circulation of air inside your greenhouse will increase your cannabis plant’s growth speed and yield. Additionally, an exhaust system helps control the temperature and humidity, while also preventing the invasion of mold and pests that thrive in hot, stagnant air.
When growing something of value, like cannabis, there will always be a threat of intruders. Whether your greenhouse is in a populated area or around hungry wildlife, any intruder could be detrimental to your overall yields and profit. Remote monitoring systems can give you peace of mind and instantly alert you when there is an unwanted presence in your greenhouse.
Knowing all the possible threats to your cannabis greenhouse helps you evaluate your specific needs, and ultimately identify the proper remote monitoring system.
Selecting the Right Monitoring System
Other factors to consider when choosing a monitoring system right for your operation include:
Base unit and sensors
Wireless or hardwired sensors
Communications to your site (Phone, cellular, Wi-Fi, etc.)
Programming and status checks
Return on investment
Base Units and Sensors
Each condition in your greenhouse that you want to monitor requires its own input on the base unit of the monitoring system. You must match your needs with the number of inputs available. A good fit for a smaller cannabis greenhouse may be a lower-cost, non-expandable monitoring system. However, larger facilities have many monitoring points and more people to alert when there’s a problem. If your cannabis operation is poised for growth, purchasing an expandable system could add value to the initial purchase because you wouldn’t have to replace your entire system in the future.
Your monitoring system should also have an internal rechargeable battery backup to ensure continuous monitoring and alerts in the event of a power outage. It is also recommended to have each base unit in a sheltered enclosure to protect it from moisture, dirt and other hazards.
Placement of sensors is also crucial. For example, temperature sensors in your greenhouse should be placed throughout the facility. They should be next to your thermostat and in the center of your greenhouse, preferably away from direct sunlight.
Wireless or Hardwired Sensors
Remote monitoring systems offer the option to have sensors hardwired directly to the base unit or sensors wirelessly connected. A hardwired monitoring system connects the sensors to the base device with wires. Generally, trenching long distances for wires is time consuming and costly. So alternatively, 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.
Communications to Your Site
Monitoring devices that use cellular communications must be registered on a wireless network (like Verizon or AT&T) before you can send or receive messages. Because cellular devices perform all communications over a wireless network, it is important that there be sufficient signal strength at the greenhouse. It is a good idea to check the signal quality in the area before purchasing a cellular product. If the cellular network has less than desirable coverage, it is possible to install an external antenna to help increase cellular signal.
When monitoring systems identify a change in status, they immediately send alerts to people on the contact list. If you don’t want all of your personnel to receive notifications at the same time, certain devices can be programmed to send alerts in a tiered fashion. It is important to consider the reach of the communications, so that you’ll be notified regardless of your locations. Multiple communications methods like phone, email and text provide extra assurance that you’ll get the alert. Also, note of the number of people the system can reach and if the system automatically cycles through the contact list until someone responds. Make sure the system allows for flexible scheduling so that it doesn’t send alarms to off-duty personnel.
Programming and Status Check
If you’re responsible for maintaining a commercial greenhouse facility, you want a system that will provide real-time status of all monitored conditions on demand. There are a few different ways to access your sensor readings. Options include calling to check status, viewing a web page, either on a local network or on the cloud, or accessing the information via an app on your mobile device. With a cloud-based system, the devices supervise themselves. This means if the internet or cellular connection goes down, the device will send an alarm to alert the appropriate personnel.
If you don’t select a cloud-based system, you will be limited to logging in through a local area network, which will allow you to make programming changes, access status conditions and review data logs. If internet connectivity is not available at your location, you will want to choose a cellular or phone system rather than Ethernet-based option.
Data history is valuable in identifying patterns and trends in your cannabis greenhouse conditions. Manually monitoring and recording environmental parameters takes a significant amount of personnel time and detracts from other important workplace demands. However, many monitoring systems automatically save information, recording tens of thousands of data points, dates and times. Cloud-based logging provides an unlimited number of records for users to view, graph, print and export data trends.
Analyzing data samples may lend insight to larger issues and prevent problems before they arise. For example, if the data log shows power fluctuations occurring at a regular time, it could be indicative of a more serious problem. Or, if the data shows signs of a ventilation fan or supplementary lighting beginning to malfunction, they can be repaired or replaced before total failure occurs.
Return On Investment
When deciding how much you should pay for a remote monitoring system, tally up the entire cost, fully installed with additional peripherals and sensors and any labor fees for installation. Then consider the value of your cannabis plant inventory and greenhouse equipment. Finally, factor in the cost of downtime, should an environmental event shut down your operation for a period of time.
Choosing the right greenhouse monitoring system and sensors could mean the difference between life and death for your cannabis plants. Understanding the conditions you need to watch and monitoring systems’ capabilities are they best way to protect your investment.
According to a press release, the State of Delaware has chosen BioTrackTHC as their partner in seed-to-sale tracking software. Delaware’s Department of Health and Social Services (DHSS) signed a contract with BioTrackTHC for the tracking and patient registry software.
In 2016, Delaware issued a request for proposals for “the Delaware Enterprise Consolidated Cannabis Control System,” which encompasses the statewide patient registry and seed-to-sale traceability systems. “Our sincerest thanks to DHSS for choosing Team BioTrack,” says Patrick Vo, CEO of BioTrackTHC. “DHSS has been wonderful to work with throughout the contracting process, and we look forward to partnering with them to provide the tools and data they need to continue overseeing the industry and protecting their patients.” BioTrack’s software was selected as the winner of a number of government contracts in other states previously for the same role.
Their software is currently used in government traceability systems in Washington, New Mexico, Illinois, Hawaii, New York and the city of Arcata, California. The press release states regulators will have the ability to view the retail data “including plant counts and usable inventory, lab results, transportation, and point-of-sale data—to perform periodic audits and ensure compliance.” The patient registry will also provide better patient accessibility through the new software with a faster turn around time and automated application processing.
BioTrackTHC provides technology solutions for businesses and governments to tracking products throughout the supply chain to the point of sale. The software systems help businesses remain compliant with regulations and monitor data for things like inventory management.
Lezli Engelking founded the Foundation of Cannabis Unified Standards (FOCUS) in 2014 to protect public health, consumer safety, and safeguard the environment by promoting integrity in the cannabis industry through the use of standards. Standards are an agreed upon way of doing things and specify guidelines or requirements for producing goods or providing services, according to FOCUS.
Standards can take the form of a “reference document, which may include specifications, guidelines, conditions or requirements for products, operations, services, methods, personnel and systems on how to design, operate, manufacture or manage something.” Peter Maguire, VP of System Applications for Lighthouse Worldwide Solutions and committee chair of the FOCUS Cultivation standard, joined the organization wanting to make a positive impact on the industry that is in line with protecting people and medical patients. He sees so much variability in the industry and the need to homogenize standard operating procedures (SOPs). “I have worked with multiple cultivation facilities and a few of them have operating procedures in place but having them in place is only half the solution- it’s critical to have the right ones in place,” says Maguire. He has twenty years of experience in contamination control in manufacturing, before entering the cannabis industry.
The FOCUS cultivation standard was created by experts who have years of experience in both cannabis cultivation, good agricultural practices and in the tightly regulated pharmaceutical industry. “FOCUS created these guidelines as a sort of roadmap for success in business; You need to keep your employees healthy and your products safe to survive in the long term,” says Maguire. We sit down with Lezli Engelking to find out how the standards are created, what makes them significant and what businesses can gain by working with them.
CannabisIndustryJournal: Why are standards important?
Lezli: Standards are the international language for trade – they exist in every industry. “The U.S. Department of Commerce estimates that standards and conformity assessment impact more than 80% of global commodity trade.” FOCUS is not reinventing the wheel with what we are doing. We are simply adapting a business model the federal government already uses. In the 80s, when the heroin epidemic swept across the US, methadone clinics popped up in every state in the country within two years. The clinics were all operating under different state, city and county regulations – much like the cannabis industry is today. The federal government took a look at the situation and decided they needed a way to regulate these clinics in order to protect public health and safety. They released a Request For Proposal (RFP) looking for an organization to create voluntary-consensus standards and a third-party certification system for the methadone clinics. Commission on Accreditation of Rehabilitation Facilities (CARF) is the organization that answered and won that RFP. CARF continues to work with Health and Human Services to maintain the standards and provide third-party certification to the clinics today. FOCUS develops international, voluntary consensus standards and a third party certification program for the global cannabis industry based on the CARF model. This is extremely important, because of the National Technology Transfer and Advancement Act, (Public Law 104-115), signed into law March 7, 1996 by President Clinton. The act requires that all federal agencies use standards developed by voluntary-consensus standards bodies, instead of government-unique standards wherever possible. Perhaps even more importantly, the Act includes provisions that encourage federal agencies to partner with the private sector in the development of standards that not only help improve the efficiency and effectiveness of government, but also strengthen the U.S. position in the global marketplace.
CIJ: What exactly goes into developing a voluntary-consensus standard?
Lezli: Voluntary-Consensus refers to the type of standard and how it is developed. Everyone who participates in the development of voluntary-consensus standards does so on a voluntary basis. Committee members must come to a consensus on every point within the standard- down to every comma or semicolon. Once the development process is complete, the standards must undergo a 30-day public review period. The process for developing voluntary-consensus standards is designated by International Organization for Standardization (ISO). ISO has member agencies in 163 countries that participate in the development of standards. The American National Standards Institute (ANSI) is the American body for ISO. FOCUS follows all ISO/ANSI guidelines in the standards development process. This is extremely important because it means FOCUS standards are suitable for accreditation and adoption into regulations according to the National Technology Transfer and Advancement Act. All voluntary-consensus standards are developed under the principles of:
Openness| Participation in the standard development process is open to individuals with a stake in the standard who bring useful expertise along with the spirit and willingness to participate.
Balance| Focus stakeholder groups involve all stakeholder groups: industry, regulatory, quality assurance, medical, law enforcement, business, research, consumers, patients and the general public.
Voluntary-Consensus| Individual subcommittees of volunteers develop each area of the standard, offering their unique expertise to form a consensus. They are not paid for their participation.
Lack of Dominance| No party has dominant representation, or influence to the exclusion of fair and equitable consideration of other viewpoints.
CIJ: More specifically, how are the FOCUS standards developed?
Lezli: To create a baseline standard, FOCUS utilized World Health Organization (WHO) guidelines for Good Manufacturing Practices (GMP), Good Agricultural Practices (GAP), Good Laboratory Practices (GLP), Code of Federal Regulations (CFR) for pharmaceutical GMPs, nutraceutical GMPs, food safety standards, OSHA and HACCP. From there, applicable cannabis regulations from around the world were added. All of this information was compiled into auditor-style checklists. Each committee member was provided time to go edit, remove or add to items in the checklist on their own. Over the next two years, each of the eight committees had monthly meetings, going through and coming to a consensus on each line item of the standard. Once the committees completed development, the standards were open for a 30-day Public Review to collect comments and feedback. The first eight FOCUS standards, completed and ready for use, cover Cultivation, Retail, Extraction, Infused Products, Laboratory, Security, Sustainability and Packaging & Labeling.
FOCUS is currently recruiting committee members to begin development of five new cannabis standards later this year: Advertising/Marketing, Insurance, Banking/Finance, Patient Care and Research. Committees will receive a list of proposed suggestions for what should be considered in developing the standards. Each committee member will develop a list to select criteria they think should be included into the standard. FOCUS will compile the lists, then committees will go through the monthly standards development/vetting process for each line item in the standard.
CIJ: So what does a business have to gain by adopting a FOCUS standard?
Lezli: Compliance becomes easily manageable with the FOCUS software platform, integrating standards, training and SOPs into the everyday operations of the business. FOCUS certified clients could expect to reduce costs, reduce risk and reduce liability by assuring they are producing safe, quality and consistent products. FOCUS certification allows a business to differentiate themselves from their competitors, and prove to their patients and customers they can trust their products. Certification also allows businesses to access reasonable insurance rates and drives interest from investors.
FOCUS is here to partner with cannabis businesses. We are there to hold their hand, by providing guidance and assistance along every step of the way. Unlike state mandated audits that delineate what a business is doing right or wrong, FOCUS is an on-going compliance management system. We are here to make sure a business runs as efficiently as possible and take the guesswork out of compliance. Under FOCUS certification, a business receives ongoing consulting, customized SOPs, employee training and a documentation management software system to track and prove compliance.
CIJ: Can you give us an update on FOCUS’ progress in 2016?
Lezli: A large milestone for FOCUS this year, aside from completing version one of the standards, is choosing an appropriate software platform, (Power DMS) to house the standards and provide an ongoing compliance management system for our clients. Power DMS also houses regulatory standards for law enforcement; health care, federal aviation and fire departments, so most agencies in public health are already familiar with it. The familiarity and access to this platform is a huge benefit on the regulatory side. It allows first responders to access the schematics of a FOCUS certified client in the event of an emergency. This is crucial in the event of an explosion from extraction equipment, or a fire in a cultivation facility, as without first identifying where the hazards are, they will not access the facility. The FOCUS software platform allows first responders access to all pertinent information through computers in police cars, ambulances, or fire trucks.
For the industry, the FOCUS software platform is equally as impressive. Not only does the platform house the standards and all SOPs, it is also complete compliance management system. FOCUS certified clients have a simple management tool that houses all training and documentation, assuring all required compliance documentation can be easily accessed at any time. The platform also allows FOCUS certified clients to provide access to governing bodies in advance of state audits –streamlining the process and minimizing time and interruption caused by state audits. The FOCUS platform tracks all changes to required documents, provides real time updates on employee training, creates appropriate traceability logs, and provides updates on regulatory changes, including which SOPs need to be changed to maintain compliance. The platform allows FOCUS to be way more than an auditing company. FOCUS is a partnership in compliance for cannabis companies wanting to maintain good business practices and stay compliant with regulations.
We have about 140 new committee members that will assist existing committees with standards updates and participate in the development of the next set of FOCUS standards for advertising/marketing, banking/finance, research, patient care and insurance. All committees will convene before 2017.
