The Way You’re Storing Weed Might Be Causing Mold

The storing of cannabis has changed a lot, and rapidly at that. Keeping your cannabis in plastic baggies stashed in your jean pockets just isn’t necessary anymore. 

However, even with improvements to packaging, other concerns such as mold have arisen. While developing in storage, mold poses a danger to both the plant’s health and yours. 

So what exactly are their dangers? 

Mold in Weed Storage

When first taken from curing rooms, cannabis is more often than not free from mold as long as producers have heeded all precautions to prevent it. 

After it is transferred to containers though, the risk of mold jumps significantly due to exposure to high humidity levels. 

Exposure will continue to grow each time the container is opened for the remainder of the cannabis’ product life. This risk can be significantly reduced, however, with the use of cannabis moisture packs. 

The two main types of mold are known as “bud rot” or botrytis cinerea and aspergillus. Bud rot is known for wrecking the plant by working from the stem outwards, killing the bud, and turning the cola into a squishy mess. 

It can be identified through gray-white wisps. Bud rot is found only on the plants and is common in colas that receive little airflow, retaining moisture. It cannot develop post-harvest. 

Aspergillus is a common mold found on more than just the buds. In high air concentrations, Aspergillus spores pose a specific danger to those with damage to their lungs and weakened immune systems. 

It can be found in soil or elsewhere with high moisture content. Unlike its counterpart, Aspergillus can affect cannabis post-harvest. 

Damage to Your Health 

After mold exposure, your cannabis will be useless after exposure to mold, and smoking an infected product can cause serious harm. Cannabis found with mold must be immediately discarded to protect user health

Any cannabis found with Aspergillus can result in infections of which high concentration can lead to regular coughing, fatigue, and hemoptysis. 

For those with compromised immune systems, it could turn into invasive pulmonary aspergillosis spreading further than the lungs and in the worst-case scenario, results in death. 


Of course, the best way to ensure that mold doesn’t happen is to pack your product into a consistently dry environment. Another way to ensure safe storage is the use of cannabis moisture packets. 

Moisture packets have two uses: ensuring 62% relative humidity and 55% relative humidity. Choose based on how dry you want your product to be, but both will keep your cannabis protected from higher humidity levels.
