Im going to be spraying my plants with a 3% h2o2 and water because of powdery mildew but dont know how much to mix per gallon?
Fungus isn't fun on your plants. Get your humidity down. h202 is a bad aide, it'll come back. Get a real product.http://www.gardenguides.com/779-using-milk-control-powdery-mildew-garden-pest-tip.html
Should do it.
And lower your RH.
