Powdery mildew is the scourge of agricultural producers everywhere, and cannabis cultivators are no exception. While it is often believed that mildew and mold thrive at higher temperatures, they actually have an affinity for moderate temperatures like the typical range used for growing cannabis. This makes it tough to outsmart and stop powdery mildew. Understanding the most common causes of powdery mildew can help you prevent it from taking over.
Common Causes of Powdery Mildew
1. Poor Air Circulation
Overcrowded plant spaces are an excellent place for powdery mildew spores to develop. Keep plants evenly spaced. This will help isolate any infections and reduce the risk of the fungus spreading as quickly. Often, an air ventilation system or fans can promote healthy air circulation. These will also help push air toward your AiroClean420 air purification system to remove all airborne threats in your grow environment.
2. Insufficient Light
Plants need plenty of light to grow and produce buds. Insufficient light is one of the common causes of powdery mildew, and it can also lead to plants appearing weak or anemic. If you’re growing cannabis indoors, ensure your grow light timers are set accurately to give plants the light they need. This also prevents water from pooling in soil, which can promote fungus development.
There is a tricky balance between providing plants with the nutrients they need and overdoing it. Powdery mildew tends to target new plant growth. Giving plants too much fertilizer may cause them to grow too quickly, which can cause a powdery mildew outbreak. Carefully monitor your delivery of nutrients to keep plants growing at a steady pace. AiroClean420 units have no harsh chemicals, harmful emissions or ozone, so your cannabis can stay fresh and vibrant.
4. Compromised Air Quality
Although fans or ventilation systems are a good way to improve air circulation, they can cause powdery mildew spores to quickly spread throughout your entire cannabis crop. It’s vital to kill powdery mildew with powerful air purification before it kills your crop. Compromised air quality can turn a mild powdery mildew outbreak into a catastrophic event. To prevent a disaster, invest in an air purification system such as AiroClean420, which neutralizes spores and bacteria as they enter the reactor chamber.
5. High Humidity
Powdery mildew thrives in humid environments. Using a hygrometer can help you monitor the humidity levels in your grow room. Seedlings require higher humidity, close to 70%. As plants mature, however, you may drop humidity levels toward 40%. During the seedling phase, carefully monitor your plants for early signs of powdery mildew. They are particularly vulnerable during this time. Through each stage of cannabis growth, AiroClean420 can provide your plants with pure, clean air to flourish.
