1. Assess the extent of the problem.

How to get rid of powdery mildew depends on the extent of the infection. If you catch powdery mildew early, you have better odds of ridding your growing environment of the mold spores. Splotches of white dust-like mold may appear on the upper or lower sides of leaves, stems, or buds. If you note just one or two areas on a few plants, isolate those plants immediately and take further action to nip the infection in the bud.

2. Use natural sprays to combat the infection.

Cannabis producers often prefer a natural approach when determining how to get rid of powdery mildew. There are a variety of homemade sprays that inhibit the growth of powdery mildew, including oils (such as neem oil or fish oil) or baking soda solutions. Use these sprays daily for 10 days or more to inhibit the growth of new mold spores.

3. Adjust environmental variables.

Powdery mildew likes a damp environment with moderate temperatures. Temperatures of 72 to 82 degrees during the light cycle and 66 to 70 during dark are ideal for cannabis plants, although powdery mildew can still grow at these temperatures. Maintain the room humidity at 40 to 60% to prevent things from getting too damp. Avoid overcrowding plants, which increases humidity and encourages mold spores to spread.

4. Use chemical fungicides as needed.

Commercial fungicides are capable of stopping a powdery mildew infection. However, they may contain chemicals that are toxic or poorly tolerated by humans. Be careful when making the decision to apply a chemical fungicide, because many medical marijuana users prefer a natural, organic product.

5. Prevent future outbreaks.

Once you have contained the immediate threat of powdery mildew, it is important to note that millions of spores may be traveling through the air in your growing environment. This is particularly true if you use a ventilation system. Prevent future outbreaks by installing an air purification system that is capable of destroying powdery mildew spores. A system like AiroClean420 prevents spores from infecting other plants and negatively affecting the quality of your entire crop.

AiroClean420 was developed by NASA to eliminate the threat of plant diseases in outer space. This proprietary technology takes in air, passes it over a bio-reactive catalyst, and neutralizes organic compounds such as powdery mildew spores. For medical marijuana producers wondering how to get rid of powdery mildew, AiroClean420 technology is revolutionary.
