How to Prevent and Remove Mold on Weed

Introduction

One of the most significant benefits of a legal, regulated cannabis industry is consumer safety. Many illegal grow operations cut corners, use harmful chemicals, and produce moldy flower. When consumed, mold or mildew can present a serious health risk for users. 

As legal cannabis cultivators, we are responsible for delivering safe, reliable products. In this post, we’ll discuss how to prevent one of the most severe issues plaguing growers - mold. You’ll learn how to avoid the environment where mold thrives and what to do if you spot the bacteria developing on your precious plants. 

Preventing Mold on Weed

Mold and mildew are microorganisms that thrive in damp, humid environments with poor air circulation. As a result, your grow room must be stable if you want to prevent mold. 

Mold Resistant Cannabis Strains

While the environment causes mold, some strains are more resilient than others. You can prevent many cases of mold if you choose cannabis seeds with solid genetics. 

Humidity and Temperature

Keep your humidity and temperature levels consistent and in the range that suits your grow. Most strains prefer a relative humidity between 55% and 65% and a temperature between 60°F and 80°. However, every strain is different and requires a curated grow environment to develop without the presence of mold. 

Spacing, Pruning, and Airflow

All cannabis plants need proper spacing. Generally, you need between two and four feet between each plant. Again, this depends on how the strain grows and your grow method. The most important thing is to ensure airflow.

You also need to regularly prune your plants to ensure all areas have airflow access and don’t become hotbeds for mold. 

Identifying Mold on Weed

Unfortunately, mold happens, but if you catch it early on, you may still be able to save the crop. Follow the tips below to defeat mold and mildew before they become significant issues. 

  • Early Detection – Regular plant inspection with a magnifying glass will help you spot mold early on.
  • Grey vs White Mildew – Look for the two types of mold: grey and white. Grey mold is most common and usually shows up in late flower or drying. White mold is powdery and traditionally found early on in patches. 
  • Monitoring Systems – Implement a regular monitoring system to ensure your plants get adequate attention. This includes looking for mold and monitoring humidity, temperature, and airflow. 

Removing Mold on Weed

Follow the steps below when you encounter mold on your plants.

  1. Isolation of affected plants 
  2. Safe disposal of contaminated plant material 
  3. Cleaning and sterilization of cultivation space 
  4. Use of natural or chemical treatments to eliminate mold
