Harvesting Cannabis With Powdery Mildew


Watch our video 4 Tips on How To Prevent Powdery Mildew

If you are growing cannabis, chances are you either have or will encounter harvesting cannabis with powdery mildew. It is one of the most devastating diseases on outdoor plants in winter and indoor plants during any season. Unfortunately, many growers suffer from it every year without knowing how to treat it properly. The best way to prevent cannabis with powdery mildew is discussed further below!

What To Do With Powdery Mildew When Harvesting Cannabis?

 First of all, it’s essential to understand how the disease spreads. Conidia (a type of asexual reproductive spore of fungi) can spread powdery mildew on cannabis. These spores are released into the air, where they will land on leaves and start growing if given enough moisture and nutrients (such as your plant).

If it’s too late for that and you have infected plants, do not worry. The first thing you need to do is remove the powdery mildew infected buds and leaves from your plants. Then, take them as far away as possible, preferably in a different room, and throw them away. If you follow these steps correctly, the chances are that you will keep the rest of your plant clean and healthy enough for harvesting at least.

Powdery mildew develops on the leaf’s surface and starts to appear as a white powder. It is easier for powdery mildew to begin in a humid, warm climate or environment. The disease attacks both mature and new plants by preventing photosynthesis from occurring correctly. This disease allows it to spread rapidly throughout the plant if not treated quickly. It eventually does significant damage to the plant and reduces its ability to grow healthy buds.

Dealing With Powdery Mildew In Your Grow Room

 The first step is to make sure that you start treating the plants, spray them early (initially), and give up on any buds covered by powdery mildew. It will keep spreading even if you leave it untreated. Not worth the risk unless you don’t care about the other buds you have.

Start by cutting off the infected leaves from the plant then spraying the plants with a solution of neem oil and water every three days and then respray them with an organic fungicide (there are lots available online). It’s best to pay attention to the type of powdery mildew on your plant because some treatments will only work for specific species.

The key to avoiding problems is prevention

 A well-ventilated grow room is essential to providing the optimal temperature and humidity. If the room is poorly ventilated, then mold and mildew will thrive. It’s also necessary to keep other contaminants like bugs out of your grow room.

One of the simplest ways to prevent powdery mildew from forming is by keeping up with a regular cleaning regime. One of the best things you can do to prevent powdery mildew is to keep your grow room clean.
