There’s nothing good about powdery mildew, especially for an indoor home grower and their prized cannabis plants. Once you see the dreaded white powdery substance, you know there’s a big problem on your hands. And much work will be demanded of you because of it. Powdery mildew certainly doesn’t just go away if left ignored and untreated. And you can’t even see it before it’s too late! It is too small for the naked eye to see when spores are traveling through the air. Plus, once those subatomic powdery mildew spores fall onto a plant, the infection will be invisible for a few days. You can only see it a few days after it has infected your plant.
What can a home grower do to prevent powdery mildew? Home growers have various options to prevent it. Many cannabis cultivation books have a lot to say about the issue, but these four prevention strategies will help you avoid powdery mildew like the best of them.
1. First, hang an Airo Home Hobby in your grow tent or grow room to clean your air. Airo Home Hobby uses photocatalytic oxidation (PCO) to literally explode subatomic powdery mildew spores into nothing but water vapor and trace elements of CO2. They are safe and easy to use, and they don’t pull much electricity. Airo Home Hobby units use 100 watts. If you’re starting a new home grow, and have the budget to do it right from the beginning, putting the Airo Home Hobby to work in your grow is putting your best foot forward. The Airo Home Hobby units are a smaller version of the original AiroClean420 model for commercial cannabis farms. After several years of success in commercial cultivation, the company finally made available a smaller unit for small grow spaces. Don’t wait and get powdery mildew, get Airo Home Hobby and prevent powdery mildew like the professionals do!
2. Next, aim to keep your humidity lower than 55% RH in your grow room or grow tent. This will likely require you to sometimes use a dehumidifier, air conditioner, fans, etc. You can even use a controller to turn on your humidity-lowering mechanisms. For example, you can set it to turn the dehumidifier on every time it reaches 55% RH. Powdery mildew won’t be able to live in an environment with under 55% humidity, so always keep an eye on your humidity levels with at least one, if not two hygrometers.
3. Be sure to use safe foliar sprays to prevent and kill powdery mildew. You can try products like Trifecta Crop Control, Monterey’s Horticultural Oil, Neem Oil, Plant Therapy, Serenade, or Copper Fungicide. Rotate these products too. The best time to spray is before lights go on, or after lights go out. Follow the application instructions on the respective label. Some may recommend that you allow 4 hours of dry time, for example. If you need to spray at another time than before lights on or after lights go out, just do not apply your foliar sprays under the grow lights. That’s a rule that will prevent your plants from getting burned badly and cause other problems too. A once a week application of one of the above mentioned sprays is usually ideal.
4. Lastly, always clean your trim scissors and gardening tools with bleach. Alcohol will help sanitize, but bleach just does a better job.
Preventing powdery mildew and other fungal diseases is especially important to home growers who live in humid climates, but even dry areas get humid hot spells. Thankfully, preventing powdery mildew has become less burdensome due to AiroClean420 and Airo Home Hobby air purification machines. Run them in your indoor grow and you’ll be as prepared as you can possibly be. And you can also run the numbers if you’re thinking about the numbers!
