Powder Mildew

Does the neem oil work as a preventive for powdery mildew or as a solution to it? I've never had to deal with it but am interested in knowing because I imagine it'll come up eventually.

I honestly don't like neem oil, for anything, it's just too oily, it does work, but you can't get the stuff OFF your plants..
a compost tea is badass for molds, those microbes are little hungry bastards
I've heard a fresh horsetail tea works too, I was going to try it but haven't had PM in a yr now
(knock on wood)

ironically when I got PM, just a basic aloe and silica spray worked, i'm wondering if aloe has some hidden antifungal property to it.
Hmmm

Did you get aloe straight from an herb or did you buy aloe in a bottle somehow? I just wanna be prepared with the humid season coming up. Michigan seems like it's gonna be extra rainy this summer.

nah I got a bunch of aloe plants, I dont' have any exp on any other way
just cut big ass blades and get a poker to "stir" up the innards, then dump the blade in a cup

Skim milk works well also

If a horsetail tea works, maybe its just the silica (although aloe never seems to hurt ) ?

could be, but I remember reading somewhere that the silica on horsetail isn't bioavailable to the plant?
could be wrong though

Hmmmm. Rather then the plant using the silica, maybe it could be the alkalinity of the silica affecting the PH of the leaf? Next time I see PM I am going to try Silica only and see what happens. Because, science!

Bingo pm can not survive in high alkaline that's why baking soda and water works

Guys most bottles on the phytosanitary treatments section of your landscape/farming store consist of the proper venom +a hint of Si . Give back caesar his own fking coins lol

I just remembered, we have baby chicks in the same room as the seedlings. They have hay for bedding, maybe the bugs came from there???

Just start closing risk vectors from design phase for 5-6 months buddy. Bugs act as carriers and this molds also carry/attract other concomitant infections.
I would flipthat veg tent to 12/12 & try a full Silica run as suggested.
