Bud rot, or botrytis Cinerea, is a common fungus that many cannabis growers will encounter in their lifetime. The fungus can grow when people are unfamiliar with city control and air circulation.

What spray can you use? We help you out!
Cannabis plants that have contracted bud rot must be dealt with quickly and safely. Depending upon any plants you are growing, bud rot can completely wipe out your harvest in a mat.
Bud rot affects the buds and the leaves of cannabis plants. The fungus starts close to the stem and then moves to the rest of the plant. It will then spread quickly to the flowers and leaves. It will ruin all of your hard work.
How do I identify bud rot?
When it first appears, bud rot attacks the stem of your cannabis plant. The stem will appear mushy and gray. As the infection spreads, the leaves appear wilted, yellow and burnt. It is hard to spot it at first because the fungus takes hold of the inside of the plant, where it is difficult to spot. By the time you do spot it, it is usually already spreading.
While looking for bud rot, it is essential to check between the leaves of the buds. Check to see if the core is rotting. If it is, you will need to quarantine that plant. You will need to bag it and remove it from all other plants. Then move on to the next plant and do the same thing. If it is infected, it has to go. Keep repeating this until you have checked every plant.
Some plants with Botrytis will develop grey webbing or white spores. The spores are a considerable concern as they can spread quickly through the air, water, or on you. To help to reduce the chance of infection by spores, you should change clothes between rooms. It would be best if you also had clothing set aside for each room.
What causes bud rot?
Bud rot is a gray mold. It develops in places with poor circulation and high. Both of these conditions allow the mold to flourish. Bud rot takes root slowly in this environment. But, once it does take root, it can spread very quickly.
Botrytis is familiar with more prominent, dense buds and plants. This is because bigger plants and buds trap moisture inside them. Also, because they are dense, they inhibit air from freely flowing through them. This creates the perfect environment for fungus to grow in. So what causes bud rot in cannabis plants?
The best way to avoid bud rot is to understand what causes it to thrive in the first place. The following is a list of factors that can help bud rot form and thrive: High humidity, mild to warm temperatures, poor ventilation, dense leaves, and dense buds.
You want to make sure to plant your plants with some distance between them. Plants in close quarters are in more danger from the spread of bud rot than plants with a healthy distance between them.
How do I treat bud rot
After Botrytis has set in, treating the plants and reversing the infection is very difficult. If more than one plant has bud rot, your entire may grow area is infected. If you wish to stop the spread, remove all infected plants immediately. It is possible that you can save some of your cannabis plants. Many growers will now choose to harvest uninfected plants to save some of their yields.
If you catch your plants at the very sign of bud rot, you can try to remremovingnfected buds. You do not want to expose any other plants to them. Wear gloves while removing the infected buds and leaves. Put them into a sealed container. You want to stop any potential spores from spreading. Sanitize anything used on the plants, or throw them out.
If your plants are flowering, don't use any fungicides. This will change the buds drastically. They will have altered taste, smell, and look.
Because of the unique challenges of growing outdoors, outdoor cannabis plants can be saturated by rain or dew. Therefore, controlling humidity outside can be a real issue. Because of the lack of humidity control around their cannabis plants, outdoor growers can be plagued by bud rot. Using an air blower of some sort can help to dry out your plants and introduce air circulation.
Prevention of bud rot
Controlling the environment where your cannabis plants are growing is the primary method to preventing bud rot. The following list will help to curb the appearance of bud rot on your plants. Always remember that prevention of something is better than curing something.
Control the humidity
Circulating air will help to remove some moisture from the plants (see below). But if you want to assist in getting rid of the moisture in the air, try a dehumidifier. There are plenty of them on the market. Just remember to get decent to a good one. They will help to reduce the conditions that fungi love to grow in.
Clean, fresh air should be constantly moved through the room you are growing to prevent the spread of spores. If you can vent the room, that is even better. Circulation will assist in removing any spores from your room altogether.
Space those plants apart
Your cannabis plants are like people. They require a little space. If your plants are crowded together, this can create a situation in which the fungus will proliferate. The closeness of the plants will restrict airflow. This will allow the fungus to spread along with the plant it is on and to the plants next. On top of this, the moisture on the plants will have a more challenging time evaporating. Plants should not be touching. This is asking for an issue.
Inspect your cannabis
Check your plants daily. If you are worried, check them twice a day. Get rid of any standing water. Remove any unnecessary plant material. Give the plants a good inspection. If you do this, you may be able to catch the infection early on. If you are perfect, you may even stop before they get a foothold.
