Maintaining Your Atmosphere Clean: Preventative Measures Against Contamination


For years we have heard about and at times skilled, white powdery mildew when increasing cannabis. It is a trouble we can see, and we have various approaches to combat it. But now far more and far more states are introducing regulatory testing on our harvests and they are seeking for dangerous substances like Escherichia coli., Aspergillis Fumigatus, Aspergillis terreus, …  just to name a couple of. Mycotoxins, mold and bacteria can render a harvest unusable and even unsellable- and you can not see these difficulties with the naked eye. How a lot would it price you to have to throw away an complete crop?

You bring in gear to handle the humidity. You treat the soil and generate just the ideal quantity of light to develop a superior item. You safe and safeguard the increasing, harvesting, drying and production locations of your facility. You do every little thing you can to safe a superior yield… but do you?

Quite a few of the organisms that can hurt our harvest are getting multiplied, concentrated and introduced to the plants by the pretty gear we use to handle the increasing atmosphere. This occurs inherently in HVAC gear.

Your air conditioning gear cools the air circulating about your harvest in a approach that pulls moisture from the air and creates a ideal breeding ground in the wet cooling coil for development of lots of of the organisms that can destroy your yield. As these organisms multiply and concentrate in the HVAC program, they then spew out into the pretty atmosphere you are attempting to safeguard at concentrated levels far higher than outdoors air. In impact, you are inoculating the pretty plants you want to maintain secure from these toxins if you want to sell your item.

The cannabis business is beginning to take a web page from the healthcare and meals security industries who have found the very best way to mitigate these dangers is the installation of a suitable UVC resolution inside their air conditioning gear.

Why? How does UVC assist? What is UVC?

What is Ultraviolet?

Ultraviolet (UV) light is 1 kind of electromagnetic power made naturally by the sun. UV is a spectrum of light just under the visible light and it is split into 4 distinct spectral locations – Vacuum UV or UVV (100 to 200 nm), UVC (200 to 280 nm), UVB (280 to 315 nm) and UVA (315 to 400 nm). UVA &amp UVB have been utilized in the business to assist market development of cannabis.

What is UVC (Ultraviolet C)?

The complete UV spectrum can kill or inactivate lots of microorganism species, stopping them from replicating. UVC power at 253.7 nanometers delivers the most germicidal impact. The application of UVC power to inactivate microorganisms is also identified as Germicidal Irradiation or UVGI.

UVC exposure inactivates microbial organisms such as mold, bacteria and viruses by altering the structure and the molecular bonds of their DNA (deoxyribonucleic acid). DNA is a “blue print” these organisms use to create, function and reproduce. By destroying the organism’s potential to reproduce, it becomes harmless due to the fact it can’t colonize. Following UVC exposure, the organism dies off leaving no offspring, and the population of the microorganism diminishes quickly.

Ultraviolet germicidal lamps supply a a lot far more highly effective and concentrated impact of ultraviolet power than can be discovered naturally. Germicidal UV delivers a very powerful process of destroying microorganisms.

To much better realize how Steril-Aire UVC performs, it is essential to realize the advised design and style. Directed at a cooling coil and drain pan, UVC power destroys surface biofilm, a gluey matrix of microorganisms that grows in the presence of moisture. Biofilm is prevalent in HVAC systems and leads to a host of indoor air high quality (IAQ) and HVAC operational difficulties. UVC also destroys airborne viruses and bacteria that circulate via an HVAC program and feed out onto the crop. HVAC cooling coils are the biggest reservoir and amplification device for microorganisms in any facility.

For the most powerful microbial handle, UV germicidal Emitters are installed on the provide side of the program, downstream from the cooling coil and above the drain pan. This place delivers far more powerful biofilm and microbial handle than in-duct UVC installations. By irradiating the contaminants at the supply – the cooling coils and drain pans – UVC delivers simultaneous cleaning of surface microorganisms as properly as destruction of airborne microorganisms and mycotoxins. Steril-Aire patented this installation configuration in 1998.

The recirculating air in HVAC systems generate redundancy in exposing microorganisms and mycotoxins to UVC, making sure several passes so the light power is powerful against significant quantities of airborne mycotoxins and cleaning the air your plants reside by.

Exactly where are these mycotoxins coming from?

Aspergillus favors environments with ample oxygen and moisture. Most pre-harvest techniques to avoid these mycotoxins involve chemical remedy and are consequently not excellent for the cannabis business.

In spite of the lack of cannabis protocols and recommendations for decreasing mycotoxin contamination, there are some simple practices that can be utilized from other agricultural groups that will assist prevent the production of aflatoxins and ochratoxins.

When recommendations are applied properly to the cannabis business, the threat of aflatoxin and ochratoxin contamination can be drastically decreased. The spot to start out is a clean air atmosphere.

Design and style to win

The design and style of indoor develop rooms for cannabis is important to the handle of airborne fungal spores and despite the fact that most current greenhouses permit for the ingress of fungal spores, encounter has shown that they can be retrofitted with air filters, fans, and UVC systems to make them reasonably absolutely free of these spores. Suitable styles have shown clearly that:

  1. Prevention through air and surface disinfection making use of germicidal UVC is a lot much better than chemical spot remedy on the surface of plants
  2. Higher levels of air adjustments per hour boost UVC program overall performance in decreasing airborne spores
  3. Cooling coil inner surfaces are a hidden reservoir of spores, a fertile breeding ground and constitute an ecosystem for a wide range of molds. Continuous UVC surface decontamination of all coils ought to be the initially program to be installed in greenhouses to lower mildew outbreaks.

UVC can practically get rid of airborne contaminants

Steril-Aire graphic four

Steril-Aire was the initially and is the industry leader in making use of UVC light to get rid of mold and spores to make certain your item will not be ruined or test optimistic.

  1. Mold and spores develop in your air handler and are present in air getting into your HVAC program.
  2. Steril-Aire UVC program installs swiftly and conveniently in your current program.
  3. The Steril-Aire UVC program destroys up to 99.999% of mold/spores.
  4. Plants are significantly less most likely to be impacted by mold…with a low price and no down time resolution.

It is time to safeguard your harvest ahead of it gets sick. It is time to be confident your yield will not test optimistic for the contaminants that will render it unusable. It is time to win the testing battle. It is time for a suitable UVC resolution to be incorporated all through your facilities.
