Do I Have Bud RotFebruary 10, 2019
Bud rot can devastate a harvest, and any buds infected with rot are no longer of any use. Some growers will turn these infected buds into oils and extracts. But this a very unsafe procedure. If you find bud rot on your cannabis plant, the only safe place for those buds is in the bin. Smoking or ingesting mould can cause serious health issues. Be very careful and wear a mask before dealing with any kind of mould.
What Does Bud Rot Look Like
You notice bud rot in a few ways, it will show subtly, as a dead, brown/ grey patch on your buds:
This is the early stages of bud rot. If you see this, it is possible that the buds are infected. If you touch this section of the bud, maybe give it a little pull, does it fall off easily?
Inside a rotting bud, will look like this:
It can be devastating to find rot on your flowers after months of hard work growing them. Any bud with rot on is no longer usable, and because of the nature of grey mould, it will infect the biggest of the buds. Lets first go over how you got bud rot in the first place.
How To Avoid Bud Rot
Bud rot, is simply mould. It is known by grey mould, and these spores are everywhere. Mould spores are a lot like seeds. They will lay dormant until they are in the right conditions for germination. Once they are germinated, they will grow, and produce more and more spores.
Mould prefers still air, moisture, and a cool environment. As your buds increase in size, airflow becomes a problem in your grow room. If you have poor air circulation, then you will have pockets of stale air, where moisture can build up.

During the night time hours, as temperatures drop, this becomes a perfect place for mould spores to germinate, and this is the source of your bud rot.
To ensure it doesn’t happen again in the future, add some extra fans to your grow area, and keep temps above 15c! To sum it up:
- Good air circulation is key to a mould free harvest
- Keep humidity between 45% and 55% during later flower
- Temperatures should drop no lower than 18c
I Have Bud Rot, How do I Treat it?
If you have found some bud rot in your garden, you have my sympathies. All you can do now is remove the infected buds and try to prevent further contamination.
First off, turn off your fans, this will prevent mould spores blowing around your grow room whilst you’re disturbing the bud.
Next, cover the bud with a plastic bag, and tape around the bottom, so it’s air tight, ensuring no spores escape.
Chop at the base of the bud and remove from the grow area. Throw it in the bin, and forget about it. DO NOT USE IT FOR ANYTHING!!
You may have more rot, you have to check your crop very carefully for more, and remove it if you do! It maybe worth considering harvesting if the problem is too bad. A few bad buds, and the harvest will be fine. The spores need to germinate to infect your plant.
Keep a close eye on your buds over the next week, if you see any more mould appear, you will have to harvest sooner than expected.
