Is botrytis curable?

It appears someone I know ended up with mildew or botrytis. They are definitely not spider mite webs inside the flowers.

I cant find any information really about if this means even the mothers are screwed and every other plant that's been touched by a tool that's came in contact with the plants infected with botrytis or just the flowering plants.

Do the mothers contain this disease and they have to be destroyed? Can it be killed in the mothers so the clones are not affected?

We are talking about sog

How does this need to be handled? No discoloration has been observed nor has any other signs of it except when u pull apart a flower cluster and see the strands. A foul odor is noticable from the affected area.

Botrytis cinerea, commonly known as Botrytis fuckeliana! Remove any part of the plant that has mold on or in it and destroy it. Also, this mold feeds on necrotic tissue so remove any dead parts of the plant. Reduce humidity in your grow room and do not let any water touch the buds or leaves! This will help slow down the spread of this plague. God, I hate Botrytis!!

Okay but what if u remove every flowering plant and material with signs of it and only have a mother left. Is this spreadable to the mothers if a knife used to cut up a botrytis infected crop is used to clone a mother?

Or would the clones from that mother be okay to use if environmental conditions are fixed ? Or does the mother have to be killed? Can the mothers be treated so that the clones are okay? What are the option in this situation ?

Just to add to this.

Air circulation and ventilation is essential possibly even dehumidification May be required.

Personally I like to keep my RH in the low 40’s during flowering with good circulation and ventilation.

When my area is full (4plants) I sometimes need to use dehumidifier.

You can get bud rot stop products. Could be a good idea to spray the mother. Clean everything with H2o2 (I mean everything) and then fix environmental variables.


But to be honest I don’t see botrytis. I see possible plant fluid that has been broken out of The stem during investigation.

Is it confirmed botrytis?

Usually botrytis goes unnoticed until you see dead or decaying bud leaves falling out of the colas etc.

Well that's too late now, there's a better understanding what caused the issue. It could have been an a/c line dripping onto a plant that caused the initial outbreak.

Now the options have to be weighed.

No dead or decaying leafs just stands of fiber like web stretched from the stems to the buds. Its definitely not mites whatever it is.

It wouldn't be good if new clones were taken only to end up back in this situation even after fixing environmental variables

Also those pics are after drying for 3 days

Like I say I still don’t see botrytis and I have suffered with it once before.


H2o2 is your friend.

Rot stop is a product you can preventative spray during veg and early flower or once you’ve noticed the botrytis.

It stopped my outbreak from getting any worse when I had it.

Well then what is causing that web like structure. It's like that on all the nugs. And the room smells like a wet towel. The humidity the whole time has been at no greater than 65 but it needs to be 40 or lower

Yeah, it can spread to wounds. Make sure you sterilize your cutting tools with something like Lysol. Remove all dead tissue/Botrytis, so it doesn't spread to the clones. Then you can start fresh with better growing conditions. If it really is Botrytis, I feel your pain!

So the mothers are still salvageable even if it was probably spread through some dirty tools?

I would say yes, if it is Botrytis then it's cultural and not genetics. I was growing Impatiens last year and had a condensation drip on one of the plants and it created Botrytis (Just saw your post about the AC drip).

It's weird, you cant see any on the plant before they're harvested but once u set them in the drying racks they start showing that stuff. The driving room is a 4x4 with a 400cfm fan on high and 2 oscillating fans. Its smokable in about 3-4 days. And it's not too much on a rack either. 20 buds were torn apart befor harvest and showed none of that. Maybe it's possible the racks didnt get sanitized properly and it spread from the racks.

It sucks because hes gona still smoke the shit. He just dries it out bone dry and dont cure it. But still he is trying to resolve the problem. Some kind of chemical that can vaccinate the plants is probably needed. Somthing that dont end up in the finished product but is applied to the mother and clones to kill any pathogens in the plant. What can do this?


I have seen a piece he tried to cure at max internal moisture and if u leave it sealed up the shit breaks out pretty bad. I'm pretty sure it's some type of mold like botrytis

Yeah it's really hard to tell. Can you post more pictures of the buds cracked open, with the mold showing? I don't know of any chemicals that are safe to use on cannabis, sorry!

No and and I know what spider mites look like. I think this is just the very beginning of a mold outbreak.

It might be spider mites! It's hard to see with the naked eye but if you look really close you can see little specs crawling around. I got this picture off of google, does it look anything like this?

No it dont look anything like that. I'm familiar with spider mites I've felt with those a loooong time ago. Those strands you see in those pictures I uploaded will turn into a cobweb looking patch of mold of left wet and dry too slow. I am almost certain this is some type of mold maybe not botrytis? I had taken a glance with a cheap microscope and did not see a single mite.
