Marc Eden interviews AiroClean420’s Dave Heffner about his experience with photocatalytic oxidation (PCO) technology which is proven to eliminate airborne powdery mildew — in cannabis grows, as well as in cheese making. For the past several years, Dave Heffner has helped roll out AiroClean420 PCO applications to stop powdery mildew at indoor commercial cannabis farms across Canada and the United States. Their technology is now also available to home growers and small grow spaces. Tune in and get up to date on the ultimate powdery mildew killing machines from AiroClean420 in the debut season 2 episode of Marc Eden’s cannabis podcast this 2021.
