Controlling powdery mildew on cannabis can seem like an impossible task. The spores seem to be everywhere. Even if you dare to spray your plants with chemicals and other toxins, there’s no guarantee you’ll get rid of the problem. The secret to fighting powdery mildew is to eliminate it from your growing environment before it ever reaches your plants. Read on to find out how.
What Is Powdery Mildew?
Powdery mildew is caused by spores from various fungi. They appear as a gray or off-white powder on marijuana leaves. Before the powder forms you may notice small pimples on the tops of the leaves.
The mildew spores are almost always delivered through the air (airborne). They can also, occasionally, be spread via people and animals. Once the spores reach your plants they will stay dormant until the environment can sustain their life. Warm temperatures, higher humidity, and crowded growing conditions will prompt growth. Once they awaken, the spores usually attack young plants first. From there, the powdery mildew spreads to the entire plant. Besides appearing on the leaves, it will also infect the buds and stems.
Over time, black flecks will display in the powder. Buds that have been infected will begin to smell damp and even rotten. Once the powdery mildew gets onto the buds it cannot be removed. It will turn the marijuana plants a pale yellow followed by brown. Then they will finally die.
Prevention Is Key for Controlling Powdery Mildew on Cannabis
Powdery mildew can seriously damage or completely destroy an entire marijuana crop. This kind of loss can be devastating for any grower, large or small. Unfortunately, once the powdery mildew reaches the plants, you can end up in a downward spiral of spraying and applying other toxins to your plants as you try to check the spread of the mildew.
The key to controlling the spread of powdery mildew is to catch the spores before they ever reach your plants. That no doubt sounds like an impossible task, but it’s not. In fact, the best way to fight powdery mildew is to prevent the spores from ever entering your production facility.
The Air-Scrubbing Solution
One of the best ways to prevent infestation is to set up an air purification system. Obviously you should do this before your plants become infected. As noted above, once powdery mildew is on your plants, there is no way to remove it.
The AiroClean420 is an effective air purification system. This air purification device was designed by scientists at NASA to remove all airborne pathogens from the space station. Our system uses that same NASA technology to scrub the air in growing environments. It very effectively removes all spores, bacteria, VOCs, blights and all other pathogens before they can get anywhere near your plants.
