In this article, we delve into the topic of "Bud Rot in Cannabis". Bud rot, a sneaky and destructive fungal disease, can turn your promising harvest into a nightmare faster than you can say "mildew." We’ll explore the ins and outs of identifying bud rot, the symptoms to look out for, and provide effective strategies for controlling and preventing this formidable foe. Whether you’re a seasoned grower or a green-thumbed newbie, our tips and tricks will help you keep your cannabis buds healthy and thriving.

What is Bud Rot?

Bud Rot, also known as gray mold, is caused by the fungus Botrytis cinerea. This fungus affects cannabis plants, especially in conditions of high humidity and poor air circulation. Our grandmothers, who were already involved in cannabis cultivation, also had to deal with this persistent pest. They used traditional methods and home remedies to keep bud rot at bay. We have adopted and refined their decades-old techniques to find effective and environmentally friendly solutions for combating this fungus.

Bud rot is not only a problem for the plants but can also be harmful to health if the affected part is consumed. It is therefore of utmost importance to recognize the signs early and take appropriate measures to prevent the spread and protect the plants.

Signs and Symptoms of Bud Rot

Bud rot manifests through various signs and symptoms on cannabis plants:

  • Early signs: Dark discoloration and softening of the plant surface.
  • Later signs: Gray, powdery mold on leaves, stems, flowers, and other plant parts.
  • Stunted growth and rot: Affected plants often show signs of stunted growth, rot, and eventually die.

Causes of Bud Rot

The main cause of bud rot is high humidity. Water condenses on plants and other surfaces at high humidity and reaches the dew point. Plants are particularly susceptible to this fungus during the flowering phase.

Prevention and Treatment of Bud Rot

There are several measures to prevent and treat bud rot. Here are some proven methods:

Dehumidification

The main measure to prevent bud rot is dehumidification. Use dehumidifiers like DryGair to remove excess moisture and reduce the risk of dew point condensation. An additional tip from our experience: Ensure the dehumidifier is emptied and cleaned regularly to maintain its efficiency.

Air Circulation

Effective air circulation is crucial to combat moist microclimates. Use fans to ensure 360° air circulation and prevent localized moisture accumulation. Another helpful trick is to place fans at different heights to promote even air distribution.

Maintaining Plant Health

Keep your plants healthy by avoiding injuries and removing suspicious plants to prevent the spread of the fungus. From our long-standing practice, we know that regular pruning and removal of dead plant parts promote plant health and reduce the likelihood of infection.

Additional Measures

Use neem oil, which contains natural fungicidal compounds, and regulate the climate in the greenhouse or grow room to make conditions unfavorable for the fungus. A special tip: Mix neem oil with a drop of dish soap and water to ensure even distribution on the plants. Apply the mixture in the evening to avoid sunburn.
