Strains have PM, should I get rid of them or what

I got 3 new strains and none of them have PM from what I see and they are all on around day 15 of flower or more. My 2 old strains have PM that I kept under control from citric acid. I barely see any PM now. I grow in separate tents, however my cuttings are in the same area and like I said the old strains had PM (no PM on cuttings) and the new ones don't... My question is would it help to get rid of the PM for good if I got rid of the 2 older strains with mild PM or doens't it matter, bc the PM is circulating around my basement? ... I have yet to see any PM on the 3 newer strains.

Why didn't you treat for PM before bringing in new clones?

If the cuts are one of a kind, you should save them. If not, you should toss them, but now that PM is in your grow space, you're far more likely to get it again.

Addressing the PM won't help the environmental issues that allowed PM to proliferate. You should still treat for it, but there's alot more going on that also needs to be addressed.

I did I sprayed my mother plants with citric acid a few times before I took cuttings.... The cuttings have no PM on them, but have been in the same space with the newer strains that never had cuttings... I'm thinking I should just get rid of the PM strains. Maybe the newer strains are more PM resistant.

By the time you can see it, it's spores are airborne.

Keep treating your plants, and when it looks like its gone, treat them some more. That shit is the plague.

Yeah I spray my plants with citric acid for like 10 days straght in the beginning of flower. I'm might go the sulfur burn route, but am scared of the fumes. I've tried 2 or 3 things already and although the citric acid keeps it at bay, I don't feel like spraying it all the time.

It truly is. My buddy had 3 years of pm on his raised bed veggies..
He tore em up and started over. Once it gets a foothold, it is very hard to control regardless of the environment

I know of someone doing a major indoor grow op whose AC drain line froze in the winter, so it entered defrost mode and started heating a grow room with 16 HPS and water reservoirs. By the time he figured out the problem, it was too late. PM spread like wildfire. I dont know what he did to fix it, and I will never get the chance to ask as he is no longer with us, but I do know that its no joke.

I use an airROS machine, emits reactive oxygen species that kills PM in the air and on surfaces.

All the other remedies are hit and miss except ros and Sulpher. I also use Regalia as a preventative. You can also sterilize your grow area between grows with the AirROS.

Ouch you've been dealing with this for awhile now. I see you got a lot of helpful responses in your thread from February. I know how our short term memories can be so I thought I'd drop a link here to your last thread, maybe check it out and see if you missed anything, good luck on getting this handed.

Deep clean
Adding UVA
Active carbon air purifier in house
More fans at a lower speed
Silica in addition to base nutes
Healthy plants
Green cure
Leaving baking soda boxes around and changing them out
No standing water
Dehumidifier


These are all the things I did to finally get rid of PM inside

I would try to dial in your environment after a deep clean of the tents. Try to keep your day and night temp close to one another and that is what ended my pm battle. Everything you read online will say air flow and more air flow but that made my situation worse. I finally got a cheap ink-bird and a small space heater and my day and night temps stay within 5 degrees and that solved it. But if you don’t clean your grow space and dial it in nothing with defeat the dreaded PM. You can keep it at bay but it more than likely will come back.

That f'ing PM , what a pain in the ass for so many people ! I've never had a problem with it until the last couple of years . I finally realized that it appeared on my indoor
grown plants due to the fact I was bringing inside several plants which were growing outside during some spells of high humidity , a real dumb ass move on my part . I've never ever brought in any kind of plant from the outdoors again and never had it again. The several times I had to deal with this scourge, I resorted to a all natural fungicide which is made from geranium oil . The product , used by state
approved growing operations ( I've personally have talked with these growers ) can safely be used during vegetation or flowering . It has never once let me down , ridding the mildew with only two applications. It was a godsend ! The name of this liquid , concentrated fungicide, which needs to be diluted appropriate volume used
Is " Banish " which I think was created in the Netherlands, goes a very long ways !
A very, very small amount after dilution , covers a shit-ton of surface area . I purchased a very small bottle , maybe 3 ounces , and still have a lot left . Do your self a favor by trying this product. It knocks the shit out of that goddam mildewry
very quickly! Hope I didn't bore the shit out of you fellow stoner . So many people use products store bought products with toxic properties. I worked in environmental research for 40 yrs. before retiring . I'm very familiar with toxic materials and their products of combustion. I am very at ease using this product.
Blah,Blah, Blah ! I'm pretty wasted !

Can you send a link of the "banish" stuff? Do you just use it on the tents or on the plant too? Do you use it in veg only or flower??

I can't dial in my environment. I have 5 tents in my basement. No way to do it. In the winter in my basement its about 66 and its 75 degrees in the summer on avg.

Once it gets on a plant can it just go away on its own if the environment is dialed in?

No. You have to kill all the fungus. Even then, the spores will lay dormant in the dirt or on surfaces around the grow. Dialing in the environment is preventative, not a treatment.

Hey Meast , fellow stoner . First of all , I don't use tents . I have huge growing rooms with shit-tons of space ! I live in a very isolated area . I can't imagine working in confined areas like that , it would be a nightmare for me . I do, however realize many people have to. I spray both the bottoms and tops of the leaves and all of thee stems , the whole damn thing . You can safely use whether in vegetative or flowering mode ! I'll send you link shortly . Just a little bit of the diluted solution covers a great amount of surface area and I only apply twice. Take care....link coming if my old laptop doesn't f up.
