Any treatments for Bud Rot should be applied in the vegetative stage as a preventative.

In cannabis plants, Botrytis causes buds to rot out from the inside, hence the name “bud rot.” If you crack open an infected bud, the inside will be a moldy dark gray or brown.
Cannabis bud rot is caused by a type of fungus known as Botrytis cinerea.

The deadened spots usually stand out and catch people’s attention, even if growers don’t know what’s wrong, they often instinctively know that something is wrong since the spots don’t look like the rest of the buds on the plant.
If you already have bud rot and can’t fix your environment (which is the best way to kill Botrytis), I highly recommend cutting your losses and taking down the plant.
Watch out. Watch plants closely for signs of bud rot in the late flowering stage, especially on large or dense buds, and especially after humid or wet weather.

Here’s an example of advanced bud rot on an outdoor cannabis plant

Bud rot is a mold that develops in the thickest parts of cannabis buds. Read for more information on how to prevent and solve bud rot before spreading!

When growing cannabis, there are multiple pests that could cross your path and try to ruin your plants. A very common type of pest are the multiple types of fungus/mold. These will grow and eventually take over your plant to destroy it. The most common type of mold that cannabis growers experience is called “bud rot”.

Do you have any tips to recognize or treat but rot yourself? Make sure to leave them in the comments below!
Fungus/mold only survives in specific environments. So to treat them, you simply need to change the circumstances of the growroom/area. Bud rot needs 3 things to survive and spread:

Even if the bud rot starts inside, there are 2 signs you could recognize pretty easy once your plant is infected:
In this phase, you still can safe some of the buds if you act on time. Make sure to cut away all infected buds and change the growroom circumstances immediately.

  • The first sign is a white, fluffy, fungus-like material appearing on certain spots around the buds. This material is very fragile so be carefull: It could contain spores leading to new growth of bud-rot if handled
  • The second sign is that bud-leafs (smaller leafs that grow in between/out of a bud) are starting to get brown and dried out/curl up. If you see this, immediatly check out the inside of those buds!

If you don’t do anything about, it takes just some days for the bud-rot to take over most of your buds. Spores already infected other buds/plants and there is nothing you can do to reverse the process. Everyday you will see more of your plant material turning to fragile, grey mushy stuff. Eventually leaving you with nothing bud brown, rotten buds. They break down easily so make sure to avoid breathing in small particles.
If you let it get this far, there is only one thing to do: Accept your loss and try another grow after you changed the environmentel circumstances of your grow area. Smoking infected buds is very bad and could cause health issues. Also make sure to clean your growroom very good before starting a new grow (Spores of the fungus will still be around).

Slowly, the signs are getting visible. The first visible calyces are turning brownish/grey and more bud-leafs are getting darker and dry out. On some spots you will see brown/grey mushy spots appearing (where the rot is coming out). You might also see the first spores appeare as black small spots that releases easily. (these can infect other parts of the plant/other plants)
