Mold in your grow room can cost you thousands of dollars if you don’t deal with it properly. Once these fungi set in, there’s very little you can do to remedy it. You could lose your entire harvest to bud rot or root rot. The most cost effective way to deal with mold in your CBD grow room is to prevent it from growing in the first place.


My Pure Environment has been treating homes and businesses in the greater Fresno area for over 20 years. We know a thing or two about how to stop mold in its tracks, and we can even stop powdery mildew in your indoor grow room. Today we’re going to impart some of that knowledge to you, so you can make sure your CBD plants stay mold-free from their first watering all the way through harvest.


How do you stop mold in a CBD grow room?


Humidity Control


The number one major contributing factor to mold growth is humidity. Controlling the humidity in your grow room will go a long way toward ensuring that your crop isn’t affected by mold.

Air Circulation


Additionally, keeping the air moving around your plants will help prevent spores from settling on the leaves or roots. Be sure to leave adequate space between your plants. This will also help make sure they aren’t blocking each other from receiving enough light.


Mold-Resistant Strains


If you haven’t started planting your crops yet, you can select a strain that’s more resistant to mold to begin with. Sativa strains generally tend to grow taller and wispier, which makes them less susceptible to bud rot. If you’re new to CBD cultivation, starting with a mold-resistant strain can be very helpful.

How do you control root rot fungus in a hydroponic grow room?


In soil-grow setups, the primary cause of root rot (Fusarium Oxysporum) is overwatering. Hydroponic grow setups tend to be more susceptible to root rot than soil setups, because of the high humidity and because the roots are submerged in water most of the time. Controlling fungal growth in a hydroponic grow room can be tricky, but it really all boils down to regulating the humidity and airflow in your grow room.


Make sure not to leave any puddles of standing water on the floor, as they can be a jumping off point for mold growth. If you have leaky equipment, patch it up and dry any moisture as soon as possible. Mold can start growing in as little as 24 hours after a water leak. You can also purchase additives for your grow water that inhibit mold, and selecting a mold resistant strain will help you buck the mold issue from the start.
