The decimalization and legalization of cannabis across the country have sparked a new industry and opportunities for hundreds of people as professional cannabis growers. Productive cannabis growing requires specific conditions; unfortunately, mold can be an unexpected byproduct of the process. There are common types of mold associated with cannabis growing that you should know about if you’re growing your own cannabis indoors.
Types of Mold on Cannabis
The most common types of mold you may encounter when growing cannabis are:
• Standard or common mold
• Bud Rot Mold (inner)
• Mold that resembles white powder
How Does Mold on Cannabis Form?
There are hundreds of different types of mold, and they are all formed from mold spores. Spores are found virtually everywhere on the planet; if conditions are right, they will latch on and multiply. The mold spores are like little seeds and are invisible to the naked eye. Once the mold spores find the perfect conditions, they latch on and begin to multiply into colonies.
When to look for mold?
Mold can form on virtually any surface when conditions are right, but they are more likely to develop during three stages of the cannabis growing process:
• Early after big leaves grow
• During the flowering stage
• During the curing or drying stage
Identifying Mold on Cannabis
Early in the growing stages of the plant, before flowering, the plant will grow large leaves, and during this stage, you may see the white powdery mold. Look for white powdery fungus on all parts of the leaves and stem of the plant. Cannabis is most vulnerable during the few weeks just before you are ready to harvest. Nearing the harvest time of the growing process, the plant has thick, dense flowering buds and exhibits optimal conditions for mold spores to multiply.
Bud rot is often the culprit during this late flowering phase. Bud rot occurs within the flower, so the outside looks okay. Bud Rot or inner mold will cause the leaves to become yellowish-brown instead of the expected dark green color associated with a healthy plant. If your plant is attacked by bud rot, immediately cut the plant and throw it away. It is also important to quickly harvest any unaffected buds. The curing stage presents ideal conditions for mold to thrive. During this stage, mold can form and multiply quickly, literally overnight, so keep your guard up.
Mold Prevention Indoors
Mold needs the perfect conditions to grow, and one of the critical requirements is the humidity of the air. Some mold prefers dry air, and others thrive in the atmosphere with lots of moisture. Without proper humidity levels, mold can not grow. You must be able to assess humidity and temperature and can control them. Install and monitor a temperature and humidity gauge closely and check it regularly. Make sure you have adequate ventilation with proper use of fans and air circulation. It is also imperative to inspect your cannabis plants for any sign of mold on cannabis so you can take action.
Mold Prevention Outdoors
Growing outside may require more work as you can’t control the environment as much indoors, but there are steps you should take to minimize the chances of mold forming. Keep your plants dry as possible, so will rid your plants of any water droplets from morning dew or after a rain. Flowers should be grown in areas outside that get direct sunlight and can catch gentle breezes.
Cannabis growing can prove to be a tricky process as it takes time, and conditions must be as close to perfect to ensure a bountiful harvest. Mold at any stage during this process can destroy all your effort. By controlling your environment and preventing ideal conditions for mold to form, it is easy to avoid huge losses.
