I've read some of the threads about powdery mildew, this is it right? Looks bad?
I'm going to use the potassium bicarbonate water method. And bath it after harvest.
Im struggling with low temps and high humidity in the garage. The other plants seem to be ok, what can I do to help prevent a spread?
Cheers all ✌🏼
@mrmullitron ya man you can control it with the potassium bicarbonate by killing it....one of the few organic compounds that actually kills the spores as well as help to remove it BUT not so suitable in flower unless very carefully brushed on because it may stick on the buds and cause some unwanted effects....soooooo....HYDROGEN PEROXIDE to the rescue lol....sorry I'm high a f right now lol.....cookies haha. Anyways....my experience with hydrogen peroxide is very good. I sprayed it all over the buds and they were fine....did not affect them badly at all except for the precaution of too much moisture on the flowers and then causing bud rot. This can be helped by a lot of extra air flow to dry the flowers off and ideally spray when lights off inside as to not burn the plants.....outdoors better in morning to spray from what I've read and done. The big thing is to not overly "soak" the buds but get the powdery mildew soaked enough that the solution can deal with the mildew.
When harvesting watch how to bud wash with hydrogen peroxide and be careful when drying to watch out for bud rot and mildew growth....ingesting cannabis with mildew or rot is NOT going to do good things to your life so....dont do it lol
Any questions we are here....tag me if needed so I get and email....pretty busy this time of year!
Cheers!
@colacody that's a banging answer thanks mate 🤜🏼
I will sort out some hydrogen peroxide and have a go at that.
Last night i upped the fans to increase air flow, just hoping it doesn't get worse it spread to my other plants.
What dilution rate did you use?
Really appreciate the advice mate!
@mrmullitron forgot to add that lol. With a 3% solution is went pretty aggressive at almost half and half....remember that the 3% solution is already pretty diluted. Also...probably 2x a week would be a good idea. Keep us updated as to how it goes.
@colacody just had a summer harvest that had to deal with both wpm as well as bud washing so I just tagged him in. There’s probably several other members here that can offer info but unfortunately not me. Good that you caught it early.
