Eliminating powdery mildew can sometimes seem like an impossible task. How can you keep powdery mildew off of your plants? And how do you remove powdery mildew after it has already settled in?
For commercial and home growers, fortunately, there are a few ways to combat this airborne fungal. If you’re growing cannabis indoors, the best way to kill powdery mildew before it kills your crop is by removing it from the air itself. Keep reading to get the information you need to know.
Exactly What Is Powdery Mildew?
Powdery mildew is a gray or white powder caused by airborne fungal spores. The powder usually appears on the leaves of cannabis and other plants. Before the powder appears you might see small blisters on top of the leaves.
Although both humans and animals can sometimes spread the spores, they are usually spread through the air in an indoor growing environment. After the air carries the spores to your plants they will stay dormant, activating when the environment becomes suitable. This is the most important time to implement our effective air purification system to keep airborne pathogens away from your plants. Our units benefit both large commercial grow rooms and smaller cannabis spaces.

Typically, higher humidity, crowded plant conditions, and moderate temperatures fosters fungal growth. Once they start to grow, they target the younger plants first, or they focus on the young leaves on older plants. Then, the powdery mildew quickly spreads to the entire plant. Besides the leaves, it also attacks the stems and, of course, the buds. It becomes more difficult to stop powdery mildew when it reaches this point in its infection.
Eventually the powder starts to show black flecks. Infected plants will start to smell like they are rotting. Once the mildew gets onto the plant, it is nearly impossible to remove. The plant will turn from pale yellow to brown before it dies.
Three Ways for Eliminating Powdery Mildew
- Apple cider vinegar. This is an old, trusted way to combat powdery mildew. Mix 2 teaspoons of apple cider vinegar (organic is best) per quart of clean water. Then spray the mixture onto your plants to help organically kill powdery mildew traces.
- Remove the infected plant. Though it may seem extreme, taking the infected plant away will keep the powdery mildew at bay before it spreads to other plants. If you only have one or two plants that have been infected, you can simply pull and replant them. Be sure to bag the infected leaves or plants in plastic bags to prevent spreading the spores.
- Eliminate powdery mildew before it reaches your plants. This may sound like an impossible task, but it’s not. The absolute best way to stop powdery mildew, and any other airborne pathogen, is to contain the spores before they get anywhere near your plants. How can you avoid harmful cannabis fungus? By setting up an effective cannabis air purification system.
