What is botrytis?

Botrytis, also known as grey mould, is a fungus that can wreak havoc on marijuana crops. This pathogen is especially feared among growers, as it can affect plants at any stage of their life cycle, from the growth phase to the flowering phase.

Botrytis thrives in conditions of high humidity and moderate temperatures , finding in marijuana plants the perfect environment for its proliferation. Its spores can easily disperse through the air and spread quickly from one plant to another, making it a considerable threat in large crops.

Once botrytis infects a marijuana plant, it can cause bud and leaf rot , resulting in loss of yield and crop quality. Additionally, gray mold produces toxins that can be harmful to health if consumed.

Botrytis is a serious problem that requires rapid and effective action to prevent its spread and minimize damage to marijuana crops.

Tips to prevent Botrytis in marijuana

Control humidity

Maintaining an environment with controlled humidity levels is essential to prevent the appearance of botrytis in marijuana plantations . The ideal relative humidity for growing marijuana is usually between 40% and 60%. Using dehumidifiers or fans can help keep these levels under control and prevent the proliferation of the fungus.

Adequate ventilation

Proper ventilation is essential to keep air circulating and prevent moisture buildup in the environment . Installing exhaust fans and fans in your grow space can help improve air circulation and reduce the chance of botrytis spreading.

Space the plants

Properly spacing marijuana plants in your grow room can help reduce humidity and improve air circulation between them . Not only does this make it easier for all plants to access light and air, but it also reduces the chances of botrytis spreading from plant to plant.

Avoid overwatering

Overwatering can create an environment conducive to the development of botrytis . It is important to water plants properly and allow the substrate to dry out between waterings to prevent moisture buildup in the growing medium.

Remove dead plant material

Removing any dead or decaying plant material from the growing area can help reduce food sources for botrytis . This includes fallen leaves, pruning debris, and any other organic debris that can serve as a substrate for the fungus.

How to eliminate botrytis in dry buds?

The presence of botrytis on dried buds can be quite an annoying problem. Before storing dried buds, it is important to perform a thorough inspection for any signs of botrytis. This includes looking for dark or moldy spots, as well as checking the relative humidity of the storage environment.

If botrytis is found on some dried buds, it is critical to remove these affected areas immediately . This may involve cutting off the infected parts with sterilized scissors to prevent the disease from spreading to other buds.

Keeping humidity under control is essential to prevent the proliferation of botrytis on dried buds. It is recommended to store buds in a cool, dry environment, with a relative humidity below 60% , to prevent mold formation.

Some natural desiccants, such as rice or silica, can help absorb moisture and prevent botrytis in dried buds . Placing desiccant sachets in storage containers can help keep buds fresh and dry.

Proper storage of dried buds is essential to prevent botrytis. It is recommended to use airtight containers, such as glass jars , and store buds in a dark, cool place to maintain freshness and quality.

Botrytis in marijuana can represent a significant challenge for growers, as it can affect the quality and quantity of the harvest. However, with the right advice and timely treatment, it is possible to effectively prevent and control this disease.

It is essential to maintain a clean and well-ventilated growing environment, as well as to regularly inspect plants for signs of botrytis. Additionally, the use of preventative products, such as natural fungicides , can help protect plants against this disease.
