You are right, genuity, Powdery Mildew spores are always present. That is why we must work so hard to keep the conditions in our rooms just right, to keep any PM spores from taking root, and spreading. Things like humidity control, air circulation, and standing water, are all vital areas to stay on top of when it comes to keeping a PM free garden.
My friend who used to own a hydro shop made a mix that was mostly bicarb but he would also mix in some lemon juice into it to kill pm. I hate using bicarb though it fucks your buds up if you get it on the hairs which lets face it if you're spraying can be difficult not to especially if you have a bad case like the one Amos posted.
It is systemic. It needs the right conditions to flower - which typically happen in flower (as you might notice your veg room often looks clean and then bam in flower they go and it shows). It is like herpes except you can cure it with diligence or if you're willing to use a harsh fungicide - which IMO is worth it but just make sure you're taking clones off that clone you sprayed and then clones from the clone you took from the original
Indeed; and thanks to all for the quick and sound replies. It's my first case, so I was sort of hoping against hope that someone respectable would tell me it was massive trichome frost.
Buds would be clean of mildew with peroxide why do ice water?
Sorry to hear that, I lost several crops this summer to a really bad PM outbreak so I can feel your pain. We had an extremely wet year this year in Colorado my organic food crop was devastated by PM, apparently snap peas get it REAL bad. The best method for eradication is apply greencure directly to affected area, 4-7 days after first spray you mix neem and some organic soap then spray that, switch off these two sprays weekly or every 3-4 days until it's gone. GOOD LUCK!Indeed; and thanks to all for the quick and sound replies. It's my first case, so I was sort of hoping against hope that someone respectable would tell me it was massive trichome frost.
Actually, I was hoping to be able to salvage at least the cola, but a good look this AM confirmed infection there, too. Losing a fem three weeks from the finish sucks, but wouldn't be a big deal, but this one hurts a little. I've never seen solid purple buds surrounded by green leaves. There are 3 others a week behind, one similar, one a little purple, and one no color. One home made jilly bean on the left. Haven't seen anything on the others
so far.
A UV-C Air scrubber is insanely expensive tho, I seen the owner of rare dankness just got one for his hydroponic system and an airbourne one, they look to be several thousand dollars.It is systemic.

Hope that wasn't too confusing. It has a pretty long half life (Eagle 20/Nova 40 and others like it).
I've had luck using UV-C light to treat but it requires insane diligence. I'm pretty sure it kills it but on big plants it's not super practical and you wind up missing spots. On clones I think it will work and it's what I'm currently using - it seems to be working.
I'd go as far to say as most plants in most peoples gardens around here probably have it either latent or full blown. You really can't see though if it's been infected.
Also there are many types of mildew. Depending on the region the conditions they enjoy vary. The kind that's common around here likes cool and damp. I believe there are types in the midwest that prefer dry heat. Which of course makes some sense, right?
It's worth looking at your local farmers websites to see what they have to say about it. The Canadian FDA had a website I used to have bookmarked on my old computer breaking down the different types that exist and the conditions they like.
You can get it tested to to see what you're dealing with which can be a huge help in solving the problem.
One other small - I've heard of people having great luck dealing with by spraying their A/C with Eagle20/Nova 40 as you can imagine the spores really collect. Me personally? I'd rather use bleach for that purpose. I think cleaning your A/C is a pretty big deal though as well as your intakes and room in general.
the h202 does clean the pm off but pm cant go thru the ice water bags above 103u so if u make full melt bubble it is even cleaner. also pm causes budrot and they both go hand in hand. filling a washing machine with a respirator can be done easily lol but throwing a party cup out is simple.
I'm using a portable UVC light. Air scrubber is a good idea too, you can get them significantly less than that for smaller rooms AFAIK.
