IV. Scenario Using UV Sterilization In A Cannabis Grow Room
Imagine a scenario in a cannabis grow room, where UV sterilization struggles to reach every nook and cranny. The room is meticulously set up with rows of flourishing cannabis plants, but lurking in the shadows are the ever-elusive powdery mildew spores.
Despite your best efforts to position UV lights strategically, there are corners where the light’s reach falls short. These shadowed areas become breeding grounds for powdery mildew, threatening the health of your entire crop.
Now, imagine the introduction of AirROS into this scenario. The AirROS system, with its advanced ROS technology, springs into action. It doesn’t discriminate between well-lit spaces and shadowed corners; it treats every inch of the grow room with equal efficiency.
As the AirROS system operates silently, it transforms those elusive powdery mildew spores into harmless carbon dioxide and water vapor. The result? A pathogen-free environment where your cannabis plants thrive without the shadow of contamination.
V. Conclusion: Elevating Pathogen Prevention:
In the world of cannabis cultivation, where pathogen prevention is paramount, it’s crucial to consider the limitations of UV sterilization. While UV technology does kill powdery mildew and pathogens, it comes with significant safety concerns and limitations in coverage.
AirROS emerges as the solution to these challenges. With its ability to sanitize even the most challenging areas, AirROS complements UV technology and offers a holistic approach to pathogen prevention. By embracing AirROS alongside UV lights, cultivators can achieve a higher level of protection and ensure their cannabis crops remain healthy and uncontaminated, from the brightest spots to the darkest corners of their grow rooms.
VI. How AirROS Maximizes Pathogen Prevention:
AirROS stands at the forefront of surface and air purification, utilizing a groundbreaking approach that harnesses the power of Reactive Oxygen Species (ROS). This innovative system operates in two crucial phases, providing comprehensive pathogen prevention for your cannabis cultivation environment.
Phase 1 – Primary Air Cleaning:
When placed within your grow room’s air circulation system or greenhouse, AirROS becomes the first line of defense. As air containing microorganisms from the surrounding environment enters the purifier’s internal chamber, a remarkable transformation takes place. The heart of the system, the reaction chamber, generates ROS. These Reactive Oxygen Species consist of five highly reactive components: atomic oxygen, singlet oxygen, hydroxyl radical, superoxide, and peroxynitrite. It’s these ROS that become the unsung heroes in the battle against pathogens.
As the air passes through the reaction chamber, these ROS come to life. They target and break down carbon-to-carbon bonds, effectively sanitizing the air. Bacteria, molds, viruses, and other pathogens are swiftly neutralized, ensuring that the air entering your cultivation space is pristine and free from potential contaminants.
Phase 2 – Secondary Surface & Air Cleaning:
The journey doesn’t end with primary air cleaning; it extends to the ongoing sanitation of both surfaces and the surrounding air. The purified air, now infused with longer-lived Reactive Oxygen Species, continues to work its magic. These include gas-phased H2O2 (hydrogen peroxide) and low-concentration levels of O3 (ozone).
In this phase, AirROS goes beyond treating the air that passes through the reaction chamber. It diffuses H2O2 and O3 into the environment, creating a two-pronged attack on pathogens. These ROS work tirelessly to sanitize the room air and all exposed surfaces. In doing so, AirROS ensures that your cultivation space remains a pristine, pathogen-free environment 24/7.
VII. Seamless Integration with Your PLC:
To provide you with full control and monitoring capabilities, AirROS integrates seamlessly with your Programmable Logic Controller (PLC). This integration is facilitated through an optional RS-485 extender box, which delivers analog signals to your PLC for remote sensor readings via Cat5e Shielded cable and our RS485X Box extender box located at the PLC.
The integration empowers you to remotely control and manage the AirROS system. The sensor, a dynamic environmental monitor, continuously assesses the conditions, providing new readings every 72 seconds. Using Proportional-Integral-Derivative (PID) controls, the system automatically adjusts its multiple stages to maintain the desired ROS set point, ranging from 10 parts per billion (ppb) and up to 30 ppb.
The controller offers a comprehensive view of system performance, displaying the last ppb reading and average O3 ppb levels. It also provides manual controls, allowing you to fine-tune power factor percentages, setpoint settings, and more. Should ROS levels exceed 30 ppb, the system will adjust the Power Factor to ensure optimal performance.
In summary, AirROS’s advanced technology doesn’t merely sanitize the air and surfaces; it actively monitors and manages sanitation levels in your cultivation environment. This dynamic control is essential for adapting to varying activity levels and bio loads, ensuring that your cannabis cultivation space remains a bastion of cleanliness and pathogen prevention, even at extended distances from the purifier.
As you explore innovative ways to safeguard your cannabis crop, there’s no better time to embrace the future of pathogen prevention. With AirROS by your side, you not only eliminate the risks associated with UV technology but also enhance the health and productivity of your plants.
