I use filter material that we use for automotive paintbooths covered with two layers of t-shirt material indoors. The t-shirt material prolongs the filter life like the sock on a carbon filter can.

Interesting. I may use a prefilter. The filters sure catch a ton of crap though. Last time I changed them there was close to 1/4 inch of crap built up. At least it didn't get in the tent which is why I filter the intakes. During flowering when the buds are sticky that crap will get all over and might not wash off. The stuff that gets in while the buds are growing is there to stay.
I just bought a large furnace filter and cut it into pieces to cover the three intakes I have open at the bottom of the tent. The fan pulls from the top. The filter material I use is supposed to filter mold spores.

It really does help using the pre-filter. I tried microfiber too but it seemed to clog too fast. The t-shirt material is cheap has good flow and can be tossed or washed. The other material is thick, and does a great job just stuffed into the intake tubes. I can't remember it's name though. We would have to trim it to size for the booth and I just kept the scrap.

I took in some clones early March and one of the clones showed PM. I threw it out immediately, but once you see it its too late. Its all over everything. Soon all my plants starting showing signs of PM.
I was planning on stopping growing for home remodeling this summer but preserving the genetics at my dads. Being that he grows i didnt want to bring that shit there so I tossed everything. Sucked.
PM is a host specific obligate biotroph. What that means is the PM you get in grapes and cucumbers different than what you get in cannabis. It uses hyphae to penetrate the epidermis of the plants leaf surface superficially. It is not systemic. It does not travel through the vascular sysyem. Just because systemic fungicides work on it, doesnt mean it is systemic.
I hear sulfur works. Ozone generators. Copper. Sulfur and copper cannot be used in flower. And sulfur shouldnt be used within 2 weeks of using oils like Neem.
My plant is to get an ozone generator and put all my grow equipment in my room and blast it all. I dont think it lives on grow equipment and is more of a myth to people who struggle to eliminate, but its cheap enough and ill use between grows moving forward
Ozone generators cannot be used with plants in the room. Also remove pets and people from the space since its bad to breath in.

AirROS creates and utilizes ROS. ROS are the sanitation/cleaning agents that prevent and destroy Molds (including Powdery Mildew), Viruses, and other Pathogens and control/eliminate Odor in the Air and Surfaces in two stages:

Why are you guys so eager to spray?
Every time you spray and soak that plant you are giving it stress and sometimes cause nute locks that also cause miss diagnosis.
Silica and cal mag help hold back the moulds bit pointless if you wet it to often.
You can use UV as a preventative.

Thanks for your comments. I've noticed in reading that the spores do need a living host, like plant tissue to be able to live, I.e. they can't live long term without one, so possibly just letting equipment sit dormant would be enough to kill off spores?

But you would be happy to know I use an air purifier in the room that has a built in UV light so I am trying to filter the air but it's not working sadly.

PM isn't systemic. People get confused because systemics like myclobutanil will "cure" a plant of PM, but I strongly recommend against using myclobutanil unless as a very last resort, and then not ever flower that plant, but grow it out for 60 days after spraying and then take cuts from the "cured" mother and then toss the mother. Myclobutanil is nasty stuff which shouldn't be used on consumables (or arguably anything), but it does work 100%.
I agree with @xtsho regarding Potassium Silicate as a preventative. Of course the most important thing is to keep your environment in check, specifically temps/humidity, and airflow. Personally I haven't seen PM for a long time, and I threw out the myclobutanil years ago.

I don't spray anything indoors. I've never once had PM indoors in all my years of growing. I'm using it on outdoor plants in the Pacific Northwest where PM can be a big problem. I use it all over the yard on vegetables, roses, outdoor cannabis, etc... It was very effective last year. I can't be walking around my yard with a UV light hooked up to an extension cord all night.Why are you guys so eager to spray?

So everytime it rains it's stressing the plant? I don't believe that to be true.
I was really surprised at how well the potassium silicate worked.
That Myclobutanil should never be used on cannabis. It belongs in the garbage where you threw it.

Didn't mean to rant
I wasn't complaining as much as I was asking.
I'd personally kill and replant/bleach.
But not always an option for everyone.

Banish fungicideLast four years outdoor no matter what I sprayed the property was covered in pm
All squash and various garden plants were loaded
This year no rain and not a spot of PM even on the PM leader Lilacs
I am sure every type of grower would love a permanent solution but once again Mother Nature rules

You have already answered your own question In very first post. If your genetics are worth saving then spray and quartine for a few months, take new clones and grow those into mothers. In the mean time do a seed run while your genetics get clean, maybe find some new keepers.
for your rooms you need to spray with prokure liquid, set off a prokure fast release packs, and until your sure it’s gone you can run the pro Kure time release during your grow with plants in the room.
I wouldn’t recommend spraying that shit for any other reason than saving genetics, and for me to feel comfortable with it, the process takes months. I’ll spray or dip small clones grow those it takes clones and then make that a new mother. By the time it gets big enough for clones it’s been several months.
That’s the only permanent solution I know of. Otherwise if you don’t get your room and genetics clean you will cycle through getting”rid” of it, just until youstart to feel confident it’s gone, then it will be back.
oh that or tissue culture (still have to clean room) but tissue culture is quite expensive. If you find someone doing TC at a decent price I’d like to have some of my genetics done to refresh them and bring back vigor too.

A vinegar and water solution is great for cleaning walls, floor, containers, etc. in a grow area too.
Have you had any problems with plants burning or getting otherwise fucky when you spray them with a vinegar solution ?
Isn’t zerotol very similar to this mixture? I mean it definitely kills on contact, but if that’s the only treatment used it will come back. I love zerotol, it’s good stuff, but it by itself only temporarily gets rid of pm.
