Definition – What does Bud Blight mean?
Bud blight, otherwise known as bud rot or bud mold, is the presence of moldy buds developing on cannabis plants. It is a common but devastating occurrence that can occur for a variety of reasons. Bud blight affects many different types of plants, including tomatoes and soybeans, in addition to marijuana of all types.
Bud blight is not a symptom of a specific disease; rather, it can be caused by a number of different issues affecting marijuana plants, such as overwatering, overcrowding, and too much humidity.
Unlike other cannabis plant infections, such as powdery mildew, which is caused by a fungal pathogen, bud blight can be caused by either a fungus or a bacterium. Even plants weakened by a pest infestation can begin to develop bud blight.

More common for outdoor plants, bud blight can also be caused by the tobacco ring spot virus (TRSV). Cannabis yields may be reduced from 25% to a 100%, depending on the severity of infection and how long a grower takes to notice it.
Bud blight can be treated in a variety of ways. The best course of action is to stay on top of your grow room’s environmental conditions so you can spot infected plants early on. For example, poor air quality can end up causing bud blight, and without proper ventilation and optimal amounts of incoming fresh air, contaminated spores can travel quickly.
A popular method of treating blight is to apply a beneficial strain of bacteria on your plants to counter the mold. There are many types of bacteria that can enrich plant health and prevent the spread of plant diseases. For example, bacillus subtilis is a naturally occurring bacterium in soil that fights blight and other fungi. It is popular among organic cannabis cultivators.
Another safe, simple solution for bud rot or blight is potassium bicarbonate, an alkaline substance that is toxic to fungi. Potassium bicarbonate is a powdery white substance that can be found at most garden centers.
Ventilation in the grow room is key for avoiding outbreaks of bud blight. Humidity levels must also be maintained, ideally below 55 per cent, and plants should be evenly spaced out so they have room to breath at all times and are not overcrowded.
