Mold, botrytis, bud rot, powdery mildew... Every grower knows that these pesky fungi can ruin a crop in a matter of days. In the worst case scenario, you have completed your harvest, only to discover that your buds have a funky and unpleasant flavor, unusable for consumption.
Even if you take every precaution as mentioned in our how to get rid of mold guide, the odds are you will still encounter these aggravating fungal spores at one point during your cultivation journey. While there are ways to get rid of mold, we feel that prevention is always better than cure. This is why we selected the best mold resistant weed strains for you to minimize the odds of having to deal with this annoying issue.
Before we present to you our mold resistant weed strain recommendations, we will explain to you what these types of strains are.
What are mold resistant weed strains?
Mold resistant strains are weed strains that are either naturally resistant to mold or have been specially cultivated for more resilience against mold growth. One of the most important characteristics of mold-resistant strains is high resin production, which the cannabis plant uses to protect itself from the elements.
For instance, Landrace strains that have been grown in the same region for years tend to be mold-resistant because they learned to adapt and thrive in wet environments, where continuously rain-soaked buds provide the perfect environment for mold growth. Moreover, landrace strains have been inbred over multiple generations and not exhaustively crossbred, causing them to retain certain qualities like mold resilience.
Hawaii strains are also known for their mold resistance. The mild climate and abundant rainfall in Hawaii provide an ideal environment for mold, forcing these strains to adapt naturally to these circumstances. Furthermore, (landrace)strains with a long history of growing well outdoors in wet climates, such as those from Central & South America Africa, and Asia will thrive in areas prone to mold problems.
Originating from Siberia, the very mold resistant autoflower strains have a naturally high resistance to mold, environmental stress, and insect predation due to the harsh conditions of their place of origin.
Finally, many mold-resistant strains that were specifically cultivated for this purpose are often a Sativa dominant strain or a hybrid with genetics that are derived from mold-resistant landrace strains.
