Prevent Cannabis Bud Rot With Greenhouse Air Circulation
Bud rot, also known as gray mold, is a prevalent disease in cannabis cultivation. It is activated when there is too much moisture in the air and has the potential to destroy entire crop cycles.
Growers cannot use traditional fungicides because cannabis plants are strictly regulated. The only entirely organic, GMP-approved technique of preventing bud rot is dehumidification to maintain low humidity.
The prevention of bud rot is undoubtedly the most critical concern in cannabis cultivation. Bud rot (botrytis cinerea) is a disease affecting many crops, including cannabis. It's a mold that looks like powdery mildew or downy mildew.
One of the most challenging aspects of combating gray mold is that mold spores are everywhere. They are airborne and can be found anywhere on the planet. It is just as easy to infect a greenhouse or indoor grow as it is to infect outdoor plants. Bud rot affects both indoor and outdoor producers.
Detecting Bud Rot - Gray Mold Symptoms
Bud rot occurs in cannabis when the fungus botrytis cinerea infiltrates the plant. The fungus then grows inside the plant before symptoms appear.
Early symptoms of bud rot include darkening and weakening of the plant's surface on and around diseased buds. Botrytis will burst out in gray fuzzy mold after the initial symptoms.
Even though it most usually infects cannabis buds, symptoms can emerge everywhere - on plant leaves, stems, flowers, or anywhere else on the plant.
Millions of fungal spores form the fuzzy gray mold on the plant. Botrytis spores can spread and infect neighboring plants once the mold is apparent. Stopping the spread and preventing a broader outbreak is difficult .
Botrytis causes shriveling, rotting, and eventually death in all plants, including cannabis.
Bud Rot Is Caused by Humidity
Botrytis, often known as bud rot, necessitates certain conditions. More particularly, it requires water to mature and begin producing spores.
As a result, high humidity is the most common cause of bud rot.
As a result, high humidity is the most common cause of bud rot. When the relative humidity hits 100% (the dew point), water begins to condense on various surfaces. These comprise structural elements, equipment, and, most critically, plant components..
Cannabis buds are particularly thick. As a result, moisture can quickly become trapped, resulting in condensation inside the buds, producing ideal circumstances for gray mold to grow.
As a result, cannabis is especially vulnerable to bud rot during the flowering stage.
Bud Rot Prevention - Mold Control in Cannabis
According to IPM (integrated pest management), prevention is always preferable to post-emergency treatment.
A combination of the strategies listed below can help avoid bud rot by reducing its presence and potential to develop.
Using Dehumidification to Prevent Mold
The most common cause of bud rot is high humidity. It's no wonder, then, that dehumidification is the most effective technique to prevent bud rot.
Growers can remove excess moisture from the air using AutoVent 's systems to control dehumidifiers.
Removing water vapor maintains dry conditions in the greenhouse or grow room despite regular plant transpiration.
Maintaining low relative humidity minimizes the possibility of dew point condensation, making it nearly impossible. Bud rot can be fully avoided if there is no condensation and no water present.
Increase Air Circulation to Improve Climate Conditions
The formation of microclimates is a typical issue in cannabis production. These are localized pockets of humid air. As a result, even after dehumidification, certain plants may still be exposed to humid conditions, allowing bud rot to occur.
Air circulation is the most effective strategy to fight humid microclimates. Air circulation is a system that circulates air 360°, generating uniform conditions throughout the space.
Keep Healthy Plants
Including healthy plants as a bud rot prevention approach may appear odd. However, plant health can significantly impact and help prevent bud rot entirely.
Botrytis frequently enters plants through wounds. Keeping your plants in good condition can help prevent bud rot infestations in the first place.
Furthermore, there is a short period between the manifestation of symptoms and full-fledged spore growth. Growers may avoid the spread of bud rot by simply eliminating infected plants.
Additional Bud Rot Prevention Measures
The most effective method of preventing bud rot is to control greenhouse or grow room climatic conditions.
However, growers can take a extra precautions to help prevent bud rot or its symptoms.
The most commonly used is neem oil. This oil includes natural fungicidal ingredients and is produced from the Neem tree, which is native to India. Growers can use it to some extent to prevent bud rot.
