How Does Mold in My Grow Room Affect My Cannabis Plants?

Mold on cannabis plants is easily preventable. However, for new or first time growers, it can be difficult to avoid. If you’ve noticed a powdery white mildew on your plants, or a brown splotchy stain on the walls of your grow room, you may be staring at a mold problem.

The good news is that My Pure Environment is here to help. We’ll give you the breakdown on how mold in your grow room affects cannabis plants, and how to get rid of mold in your grow tent to ensure that your product is mold-free.

How do I get rid of mold in a grow tent?

If you find mold on the tent itself, a mixture of white vinegar and water will kill most mold on fabrics. It’s also non-toxic, so it won’t affect your plants. If you have white powdery mildew on your plants, there are some steps you can take to remove the powdery mildew. But you may want to take a moment to assess whether it’s worth removing the mold.

In a smaller scale grow op, like in a tent, it may be worth taking the time to treat the plants and remove the white powdery mildew (WPM). Most large scale growers will simply snip the affected areas off and move on. If you do want to remove WPM from your plants, here’s what you need to do.

How you can treat white powdery mildew on cannabis plants:

The mold-stopping effects of vinegar are well known. You can use apple cider vinegar (ACV) as a natural mold remover. Just mix 2 or 3 tablespoons of ACV with 1 quart of water and spray it on the affected areas of the plant.

Spray the vinegar solution on the affected area and let it sit for at least an hour. Try to spray during dark hours if possible. The plants are less likely to absorb liquids on the surface of their leaves after dark. Wipe the leaves with a damp cloth to remove any residual mildew.

If you can’t do this during dark hours, you may want to move the plants outside to treat them. This will help ensure you don’t spread mildew to other parts of the tent or to your indoor space.

Don’t let mold affect your cannabis yield!

Mold can decrease a cannabis plant’s yield and even kill the entire plant. It’s always a good idea to take care of mold on your plants and in your grow room as soon as you identify it.
