Hydrogen peroxide spray.

Apple cider vinegar spray .

Both diluted with water. 

 

Neem oil or sesame oil spray.

 

If you get hot dry weather for the next couple weeks , you may be ok as it can die off if it's over 90f .

 

Cold or damp/wet will accelerate the mildew.

Not a good idea in flower though I don't think.

Depends where the mildew is I'd say. 

I wouldn't use neem or sesame on the buds. 

I might use hydrogen peroxide or apple cider if it was gonna be raining a lot. Depending on the density.

 

I'll happily listen to alternatives .

@CheechChongReturns Yeah I suppose it could be the lesser of 2 evils, but I would definitely be concerned about contamination, I guess if its already going to turn to rot it would be worth a try at least.

 

TBF I'm not sure they're really is an alternative to spraying something on them, other than like you where saying raising the temperature or using ozone. But obviously that is only impossible indoors.

@MindSoup just figure peroxide is used ina diluted bud wash . Think I recall apple cider vinegar was the old bud wash before hand.

 

Both are meant to be ok with plenty water rinses . 

 

OP might have been lucky and just had it on leaves which is why I threw in the oils . 

 

Pics and more info always help when trying to offer up possibilities.

 

Personally I'd process it rather than take any risk.
