How To Remove Powdery Mildew From Cannabis Plants

January 11, 2017

Powdery Mildew is one of the worst things that can happen to your cannabis plant. It is a fungal disease which forms if your grow environment has high humidity and moderate temperatures.


Neil from Grow Pot Cheaply recently noticed powdery mildew on several of his cannabis plants and decided to film a video on it. The powdery mildew was found on the bottom of his plants in his indoor garden. One of the contributing factors to why it formed was because of the lack of air flow in his grow environment. Therefore, he discusses the importance of an oscillating fan. In the video below, Neil also talks about how to remove powdery mildew from cannabis plants.


Strains that Neil is currently growing:

  • Blue Dream

  • Critical Kush

  • Lemon Sour Berry

  • Incredible Bulk

  • White Widow
