These units vary widely in their intensity, and quality. Most cannabis growers who have already used UVC to protect against Powdery Mildew, and Bud Mold, and have been disappointed with the outcome, have done so with a form of a handheld unit. So, even if you don't completely eliminate Powdery Mildew and Bud Mold, UVC treatment will still reduce it in some capacity. In many applications, a 3-log or 4-log (99.9% and 99.99%, respectively) reduction of bacteria is the goal, and anything beyond that is a bonus. The proper amount depends on the intensity of the light source, the amount of time it's exposed to the light, and how close to the plant the light is located. Too much UVC can burn the cannabis plants. Too little UVC won't reduce Powdery Mildew enough. How UVC Combats Powdery Mildew in Cannabis GrowsĪn adequate dosage of UVC light will act on Powdery Mildew, and Bud Mold, just as it does on other DNA-based microorganisms – it will damage its DNA such that it can no longer replicate, and therefore will no longer be viable. Some molds require 50 times higher dosage as compared to bacteria to achieve the same level of reduction. Although UVC can cause a painful (but temporary) reaction on exposed skin and eyes, simple precautions, such as inexpensive goggles, and wearing clothing that covers skin, will serve as adequate protection for any personnel who may need to access an area where UVC lighting cannot be turned off during their accessīacteria, molds, and viruses require varying total dosages of UVC light for inactivation.UVC is entirely blocked by the ozone layer and oxygen in the atmosphere, is non-penetrative, and can only attack what it can "see".UVA, and some UVB from the Sun, reach the surface of the earth, and UVB contributes to plant growth and development.Ultraviolet light from 100-400nm, can be divided into 3 bands:. ![]() Visible light falls between 400-800 nanometers (nm) in wavelength. ![]() Coupled with innovative and proven energy-emitting lamp technology, effectively using UVC to reduce Powdery Mildew and Bud Mold - as it has been used in HVAC systems, and healthcare settings – is a process of applied math and science, rather than one of smoke and mirrors. Use of the Suncatcher Personal Sanitizing Wand is an important precaution, but not the only precaution that one should take to protect oneself.Using measurement, calculation, and experimental data, the precise dosage of UVC energy has been established to inactivate mold spores, bacteria, viruses, and other undesirable microorganisms. To avoid microbial infection, one must take a wide range of precautions. It is important to realize that use of the Suncatcher Personal Sanitizing Wand does not guarantee that the user will avoid illness. Please note: Opportunities for infection are abundant and virtually everywhere, so Therefore, as long as the nm frequency of a germicidal lamp is well controlled within that range, the microorganisms will be destroyed effectively. Scientific research has proven that the most effective frequency for microbial destruction is between 280nm and 200nm, which is within the UVC band.
