Mold can be a difficult problem to deal with in marijuana growing, because it can strike at any phase of the process. From harvesting to drying and even up until someone smokes it, CBD bud can be susceptible to mold growth. If you spot white powdery mold on your plants, or grey wispy mold on your buds, it’s time to take action.


My Pure Environment can help you treat your marijuana crop for mold. If you’ve discovered white powdery mildew on your plants, we can treat your grow op immediately to prevent the mold from spreading to other plants. Today we’ll discuss how to spot mold and how to identify white powdery mildew on cannabis plants.


How do you spot white powdery mildew and mold on buds?


White powdery mildew looks just the way it sounds. It’s whitish in color, has a powdery appearance, and is typically found on the leaves and stem of the plant. White powdery mildew is most common in outdoor marijuana cultivation.


Mold growth on buds is a little trickier to spot. It’s usually greyish in color, but it isn’t always visible from the outside of the bud. You may have to break the bud apart and inspect the inside to determine if there’s mold or not.


Always make sure to inspect your plants regularly for any sort of fungus or parasites. Leaving these problems unchecked can result in lower yields and even the loss of your crop.


How do I prevent mold from growing on my plants?


The best way to prevent mold in your indoor grow room is to make sure there’s plenty of ventilation. Pruning your plants, especially the lower half, can help improve airflow. You could also burn sulfur in your grow room as more of a preventative measure. The sulfur prevents spores from taking root on any surface that has the burnt sulfur particles on it, but it won’t kill mold that has already set in.


Preventing mold in an outdoor crop is a little trickier. Because you don’t have any control over the outdoor humidity, you could have a hard time. The best prevention method for outdoor grows is to adequately prune your plants to increase air flow and defoliate your plants regularly. After it rains, you can gently shake each plant to remove excess moisture.


If you’ve had a hard time with mold in the past, and want a more straightforward solution, there are strains of marijuana that are less susceptible to mold. Starting with a mold resistant plant will give you an advantage in fighting the difficult battle with mold.
