The top, chemical free method to prevent Powdery Mildew, fungus, bacteria and other biological contaminants from posing a risk to the cultivation of Cannabis.

1. Powdery Mildew
Prevention

2. • Canadian company founded in 1995
• Develops & Markets proprietary Ultraviolet Air
& Object Purification Systems
• Manufactures complete line of UV systems for:
Residential
Commercial
Institutional
Medical
Military Applications
• Global pioneer in Ultraviolet Air &
Object Purification

3. Ultraviolet UVC Germicidal Light
UVC Germicidal Ultraviolet wavelength (254nm) is effective in
penetrating the cell membrane breaking the DNA structure of a
micro-organism. DNA sterilization inhibits reproduction.
Micro-organisms such as mold, bacteria &
viruses will be destroyed with the required
concentrations of germicidal energy.

4. We are now utilizing this expertise in other industries…

7. Powdery Mildew is a common fungus that occurs on:

8. The fungal disease powdery mildew affects a wide variety
of plants and takes away a plant’s nutrients. This causes
the plant to bloom less and become weaker.

9. When the Powdery Mildew fungus begins to take over one of your plants, the
mildew that forms is made up of many spores. These spores
carry the infection to other plants through the wind.

10. Think of a Dandelion when you blow it.
It’s seeds spread via the air to other plants.

11. In many cases, cannabis growers have to
destroy or send the product to extraction
like throwing $$$ in the trash

12. How was Powdery Mildew Controlled before?
Regulations from the tobacco industry are being adopted to eliminate the use
of a majority of the pesticides and fungicides that battle Powdery
Mildew, Botrytis, and other fungus.
Leading the grower to search for a chemical free,
non-toxic, non residue solution.

13. Air vs Plant Surface UVC Disinfection
Airstream Disinfection utilizing
existing HVAC system

14. Sanuvox Biowall Sizing:
Return or supply duct size, CFM, cubic volume of room and
determine air changes per hour. 8-12 minimum
Objective is to achieve 99% or higher disinfection on Powdery
Mildew within every hour the Biowall is operating
Locate an install position so as to not affect the dark growing
cycle
Require air to be brought into the HVAC system to be treated,
growers do not like anything being put into the grow space
such as ions, ozone, plasma, oxidizers, etc. as they can and
have damaged the plants and terpenes within the plants.

17. No forced air system, Stand alone units are available
6,500 cubic ft.
25,000 cubic ft.

18. Odor Exhaust
Technologies

19. Ultraviolet UV-V Oxidation Light
UV-V Oxidation Ultraviolet wavelength (187nm) is effective in
the oxidation and removal of carbon based odors such as those
created from the cultivation of Cannabis. This wavelength is
effective in exhaust ducting and not recommended within the
cultivation rooms

20. FLOWER ROOM B –
Before and After Sanuvox Biowall
Plants in Flower Room B – cycled every 2 weeks –
60 days in room total
Plants with powdery mildew
Plants with Botrytis
Passing mold CFU test easily
lbs of infected product destroyed or discarded
200 200
35 4
20 1
No Yes
6 lbs 1.5 lbs
Before UV After UV
*Biowalls only ran 12 hours a day
** Next steps – run Biowalls 24 hours a day, add UV to
other flower rooms, add UV to Veg Rooms

21. Average price per ounce of Cannabis at time of study -
$300-$500
4.5 lbs equates to 72 ounces
$21,600 worth of cannabis discarded
60 day harvest cycle – 6 times a year
2018 -Current wholesale $1,400/lb - $6,300 recouped
Within 1 harvest, the (3) Sanuvox Biowalls were easily paid for in Flower Room B

22. Additional Benefits:
- 90% reduction in spraying the plants with organic
fungicides – (before Biowall this was their primary
method of battling PM)
- Reduction of labor costs associated with spraying
- Increase in Terpene smells making a stronger product
- Consistent passing of CFU testing with lower Mold
