To prevent disaster, cultivators need to ensure they follow curing processes that properly dry buds, preventing mould from popping up. If you can, place a hygrometer in your curing jar to monitor humidity levels, “burp” your jars daily (open them up to let in fresh air), and check your buds to rule out fungal growth.

A particularly devastating fungus, Fusarium can potentially lay waste to an entire cannabis crop. The species can lay dormant for years before becoming active and obvious—making it considerably harder to detect than many others.

Sooty mould, named after its dark and flaky appearance, doesn’t actually directly attack cannabis plants. Instead, it gobbles up the excrement from sap-sucking insects.

Indoors

Causes:

Mould exists everywhere, to the point that all cannabis flowers will have a little (besides those cultivated in sanitised indoor spaces). Although mostly inert in small quantities, even tiny amounts of toxic mould can cause problems.

A type of fungus, “mould” encompasses a large group of taxonomically diverse species. Much like other fungi, they branch out while forming a multicellular network of small filaments (hyphae), forming a dense mass of fibres known as mycelium.

Symptoms:

Root rot is similar to bud rot, although it happens on the roots. This happens in soil when you get fungus gnats or when you overwater for a long time but it is more common in hydroponic setups .

We recommend keeping a clean growing environment, even if you never got mold or fungi, it is a great way to prevent it.

Botrytis (also known as bud rot or grey mold) is a type of fungus that affects plants in general. In cannabis, it develops inside the buds and it slowly starts to grow outwards, making it difficult to spot in the early stages.

Identification

Powdery mildew can be a little bit easier to treat. First of all, you should adjust the temperature and humidity in your growing space, and remove affected plants from it. You should also check the other plants, as spores can easily spread to all the plants around.

Also, mold produces spores (and there’s a good amount of spores in the air anywhere you go). Mold spores can stick on your clothes and can be brought into your growing room. They need only humidity and a slightly warmer condition to start developing.

The inside of the buds should be the same color as the outside, if you see brown or grey spots, it will most likely be bud rot.

If you can’t see signs of mold but you notice the leaves drying or if you think the buds are not growing properly it can be a fungus starting to develop in your buds.
