To get rid of powdery mildew, first use an air purifier from Airo Home / Hobby. Nothing else will be as effective or efficient to get rid of powdery mildew for good. Airo Home / Hobby uses photocatalytic oxidation (PCO) technology to clean the air of harmful contaminants including powdery mildew, botrytis, and other airborne fungal plant diseases. It works by killing subatomic airborne powdery mildew spores in the air, resulting in clean air and a powdery mildew free zone. Each Airo Home / Hobby can handle a 12 x 10 x 10 room and uses very little energy despite the fact it operates 24/7.
There’s more strategies to help you get rid of powdery mildew once and for all. Besides using the Air Home / Hobby, home growers should dial in proper humidity levels, air flow and air exchange. These aspects of your home grow environment should be managed carefully. Humidity percentages should be less than 60% RH to make the environment as inhospitable as possible to powdery mildew. However, if you can get it below 50-55% RH, even better. If you were to have 70% + RH on a consistent basis, then you’d be creating an environment conducive to powdery mildew.
You also need a good foliar spray regime to protect your plants from pests and diseases like powdery mildew. Many pest control sprays like Trifecta and Organocide prevent powdery mildew and aso kill pests like spider mites and aphids too. Win-win!
While you’re at it, keep your entire grow space as clean as possible. This includes regularly cleaning walls, floors, vents, fans, etc. As a general rule for indoor cultivation, it’s vital to clean your grow space thoroughly, especially if you ever have an instance of powdery mildew.
Experienced growers will tell you to have a multifaceted approach to increase your odds of preventing powdery mildew. They are correct in their approach. There isn’t just one silver bullet needed when it comes to getting rid of powdery mildew.
What else can you do to get rid of powdery mildew?
If you’ve been having recurring powdery mildew infestations, and you have a rug or carpet in the area, they could be one of the biggest contributing factors to your re- infestations. In which case, it is recommended that you remove the carpets. Keep carpets out of your grow space all together. They are suitable there.
The other key steps to prevent powdery mildew include using foliar sprays in a preventative nature. Products like Serenade, Trifecta, Green Cleaner, Organocide, Copper Fungicide and Lost Coast Plant Therapy are quality foliar sprays to prevent and get rid of powdery mildew. The most economical foliar spray is Organocide, and the most expensive is Trifecta.
The airflow in your indoor garden should be light, not strong. Get your leaves to dance lightly in the wind as a goal. If you’re in a very small space, you can point the fan towards the wall to generate some light airflow, instead of blowing it directly onto the plants. Be careful because when you blow strong air directly on cannabis plants, you can stress it out or even damage it.
Remember, you’re not alone in trying to get rid of powdery mildew. Many indoor growers face this problem with powdery mildew around the world. Hopefully now you will be better prepared to prevent it and get rid of powdery mildew in your home grow forever.
