I edited out the non-self-aggrandizing phrases…somehow still 1/2 of the post left.

hey vernal man, you want to join the group? I can now see you suffered incredibly at the hands of infections. That story about the virus was crazy man and those other buggers that came in before that. Icky shit man, you want to share with the group? I promise I put the monkey away in the cage.

ok, I think anyone left now is ready to learn. I’ve got a page copied from the internet I’ll lay out and deal with some total garbage in most write ups. The reason I think most articles about powdery mildew are garbage because they are cannabis copypasta. Lets start and you can look this page up online if you want, but it’s just a random example of toxic garbage combined with real answers.
Spores
How do I Recognize, Control, and Prevent Powdery Mildew?
Introduction
- Powdery mildew is a common fungal disease that can seriously damage indoor and outdoor crops. TRUE
- Powdery mildew can rapidly infect crops in both vegetative and flowering stages, coating leaves, stems and buds in fungus. TRUE
- Powdery mildew typically thrives in cool, damp, shaded and poorly ventilated areas. Airborne spores brought into the grow room land on leaf surfaces and will germinate given favorable conditions. High night humidity levels often trigger the growth of mildew spores. Powdery mildew can attack indoor crops year round. Powdery mildew is almost impossible to stop in late flowering, so early detection and control is essential. MISLEADING
This is the first paragraph in an article I would actually consider quite good, compared to most trash. Problem is, “Powdery mildew typically thrives in cool, damp, shaded and poorly ventilated areas” is wrong, followed by “Airborne spores brought into the grow room land on leaf surfaces and will germinate given favorable conditions.” That’s absolutely correct, except the favorable condition is your plant is transpiring. Which they all do. “High night humidity levels often trigger the growth of mildew spores.” This line is a lie… because favorable conditions are: your plant is alive and transpiring. The rest of the info, is absolutely true. Where it talks about detection in veg and control. Totally, never spray sulfur in bloom.

ok we’ll keep on going alright. The same page it keeps going there’s important stuff here.
Identification & Recognition:
Identification: Symptoms and damage: Early signs of powdery mildew include white powder/fuzzy patches on leaves (usually low in the canopy) and a fuzzy white coating on lower stems. Note: powdery mildew can be wiped off the leaves for a quick visual check. TRUE
- These fuzzy mycelium patches produce airborne spores that rapidly attack adjacent plants; mildew will eventually coat leaves and entire plants, reducing photosynthesis, plant vigor and bud quality. TRUE-ISH It’s actually an Ascomycetes spore spitter.
Mildew-Prone Gardens, Plants & Environments: - Perpetual harvest, dense scrog/sog systems, and damp basement grows are particularly vulnerable to powdery mildew. Note: strains vary in their susceptibility. FALSE
- Plants on the edge of a garden, in corners and under stress are attacked first; infection usually starts in the lower canopy where conditions are optimal. As infection progresses, mildew will spread to the top of the plants and finally attack the buds.FALSE That only APPEARS to happen.
- Powdery mildew is favoured by dry atmospheric and growing conditions, moderate temperatures, reduced light intensity, good nutrition and succulent plant growth. TRUE
- For this reason it is a very common disease in later summer and Autumn (Fall), but it can be a problem in protected growing areas such as greenhouses, conservatories and grow rooms, on a year round scale. All mildew spores are spread via wind or air movement, and certain insects can also carry the disease. MOSTLY TRUE
- Unlike other fungal diseases, such as downy mildew, the powdery mildew spores don’t require a film of water to be present on the leaf surface to germinate and infect the plant tissue. In fact, if the powdery mildew spores are in contact with water they are inhibited to a certain extent. mediumer growers can achieve some control over powdery mildew by simply spraying the leaves with a garden hose in the afternoon to help prevent infection. Powdery mildew spores germinate best in a temperature range of around 22 – 31 C (72-88F), and in shaded areas of the crop, so it is more severe in closely planted crops. If the spores, entering a growing area, make contact with a plant under conditions of reduced light intensity, a temperature of 22 – 31 C (72-88F), and absence of moisture then germination will occur within two hours, and infection will be two days later. TRUE
I’m not sure what the end part is about, but that’s not applicable to inside grows. In fact lots of this info isn’t.
Edit:
The article goes on and there’s lots of gibberish about wanting to believe in university studies but he’s going to “keep an open mind”. Egads, humans. Anyways then he finally kicks into pro-mode and lays down the solution:
An effective sulphur application rate would be 110-220ml per 100 litres of water of a `suspension or wettable powder’ product, when the fungus is first observed, followed by repeat applications two weeks later.
woah…where have I heard that advice before?

When do we get to the preventative part?

oh yah! So you have to be biosecure right? The most important part is not to bring the organism inside your grow. If I’m bringing in a plant I have to wash that thing down and examine it at a microscopic level if there is any question.
The containment idea for the new arrivals is a really good idea, so you can make good and sure it’s clean. Use a magnifying glass or microscope, it’s a good idea.
biosecurity is a really…really…really good idea, essential. You can go so far as to change your clothes if you think the danger is high, before you enter the grow.
Here’s the bottom line right? Always make sure…you don’t bring the mildew in. Even to your green house. The clones must be decontaminated first.
If you fail at biosecurity, make sure you kill the fungus with sulfur and learn from what went wrong.

I would say it’s all about contaminated plant material. I mean…that’s all there is to it right? Don’t bring it in on your clothes, shoes. In your hands. In a pot. None! Not until it’s clean!

lol, thanks. If I can get people to actually TRY the sulfur and cure their problem. I will be so happy…I might crap my pants. So far online it’s really hard to get people to even try it. The trauma of infection does things to your mind and it’s hard to shake. Knowledge is key to moving forward!

I am also going to ask Jesus if he knows someone struggling with it. Someone at the contest complained about it and I told em to nuke it from orbit with sulfur. He’s really busy with planting season and the turd he got to make his thousands of clones botched the operation cost 10% they died. So he’s dealing with that mess AND some crazy fucker is attacking his truck with a gas can, fuck me reality is a crazy place to live lol! Also, I think I can contact some of the poisoners crew, the justice league, I know for sure there are some suicidal units dealing with this shit(P. mildew). They are all so paranoid though, because the cops have been sniping their associates one by one on cannabis charges. The heartbreak of wiping out the mildew I only got to study it for a year, but learned so much!

It’s just part and parcel of farming lol what are these traumas you keep talking about. If you can’t emotionally handle bugs and mold and occasional losses this ain’t the hobby or profession for you.
Get problem, spend money and time fixing it. No different than any other endeavor.
Greenhouse operators don’t cry about it, they just get back to work lol.
Mildew happens, everywhere everyday. Gotta be the constant gardener.

Acquire mildew. Realized air exchange was fucked up. Try to fight mildew with suffoil (sulphonated oil) and potassium bicarbonate and silica. Fail. Spend $50 on Eagle 20. Mold dies.
