In order to prevent the growth of fungus such as Botrytis, Penicillium, Powdery Mildew that could be a threat to the growth of Cannabis, dust knights custom real-time performance and sizing that utilizes CFM, duct dimensions, and the area being treated. The objective is to clear the air of fungi at the rate of 95% or higher every hour by changing the air 8-12 times per hour the unit is operating.


  • Providing a consistent environment for repeated harvestation.
  • Helping in the enrichment of terpenes
  • Helping in the enhancement of aromas
  • Eliminating up to 99.9% of airborne fungi every hour
  • Reducing the use of fungicide by up to 90%
  • Reducing the costs of labour relating to the fungicide use
  • Improving microbiological state testing compliance

How It Works


The Dust Knight system has the power of the sun emitting UV rays which disinfect the air and prevent contamination of crops. Our high-intensity UVC chamber. A patented high-intensity UVC chamber, directly integrated with the cultivation facilities HVAC system, continuously kills up to 99.9% of airborne Powdery Mildew, Mold and Bacteria every hour.


We use high-intensity T6 germicidal UVC lamps that are mounted parallel to the airflow on anodized aluminum parabolic reflectors for the total 360-degree disinfection of contaminants.


Dust Knights makes sure our system eliminates the need for fungicides. This process is a completely green solution that is non-toxic and non-invasive that leaves zero residues and no environmental footprint.


In order to achieve up to 99.9% disinfection on one pass inactivation, our systems are tested by the U.S. EPA and Homeland Security for Biological Inactivation Efficiency by HVAC In-Duct Ultraviolet Light Air Cleaners.

Powdery Mildew

One of the most widespread diseases of indoor and outdoor plants is Powdery Mildew which is responsible for significant financial losses. This disease is also a serious threat to the growth of Cannabis. These infections don’t cause plants’ death, however, the consistency, yield, value, and aesthetic are reduced significantly. In these cases, the growers have to destroy the plants. For indoor cannabis, powdery mildew is more problematic in the fall and spring when the humidity is relatively higher, however, it can develop at any time.

When there is a clear understanding of the disease, the organism affecting the crops, and the factors which favor the development of the disease can contribute to the successful management of Powdery Mildew.

Dust Knights provides high-intensity UV-C germicidal air disinfection within adequate air filtration within the grow facility is the most powerful way to eradicate Powdery Mildew.
