    Yes the best thing is fans blowing all the time but not blasting plants. Eagle 20 is the best but it pretty much toxic. Just curious what people here like. I know that Bonide Copper spray is pretty good.

    Green cleaner is more of a pm wash. I prefer to use green cure, but too much of it causes the leafs to yellow and slightly burn, so I rotate through them.
    Green cleaners description says it, "Washes powdery mildew right off the plant."

    I have also used apple cider vinegar, and milk to rid PM.

    Eagle 20 is way more toxic than PM

    And PM is everywhere, when given the proper environment it shows

    Usually PM is due to poor growing conditions and can be remedied with a few simple organic products and a proper environment

    Eagle 20 is some nasty shit and has no place in a cannabis garden

    Neem oil during veg works well as a preventative. I've also heard of using fungus teas as a foliar also.
    Disinfect the entire room or it will be a constant problem.

    I think the mix is 90% water and 10% skim skim milk. How about ACV? Thanks.

    It's an ancient plant, found pretty much anywhere in North America and around the globe (wiki it). I have a few spots around where I live where I can harvest a bunch, dry it, and make teas with it year round. It's high in silica and very good fertilizer as well.

    I have not seen powdery mildew in my garden for like 5 years so I don't really use it other than mulching with it.

    It's the only plant that reproduces itself via spores, anyway, I love that shit, u can also make tea to drink and I love the taste myself.

    I use a simple formula that is very effective...also used it on a Zenna flower plant that was so impacted with PM...just wish I had before and after pic's of it

    1 gallon of water
    1 tablespoon of baking soda
    1 tablespoon of vegetable oil
    1 tablespoon of dishwashing liquid

    Mix the ingredients together and add them to a spray bottle.

    Spray your plants just before lights out (or just before sunset if growing outdoors)

    a fan blowing around 80% humidity isnt going to stop fungi sorry. I read many mold growers here already using a fan to spread their humid spore rich air around their space to no avail.
    I've brought infected vegging plants from my greenhouse into my sealed controlled rooms after hosing them down outdoors with water and drying them in the sun. I transplanted them in fresh indoor dirt and all went well.
    they survived, flowered indoors and never saw the mold again. My rh never exceeds 50% indoors because I employ a dehumidifier to keep it that way. i am convinced mold doesnt flourish on plants if humidity is controlled. I've seen pm on old leaves at the bottom of my clone dome, fuzzy and all, no issues except an embarrassing removal. I am sorry this happens to growers though, mold is a bummer, shits always hanging out where the dehuey isnt right?

    Sm-90. It's a wetting agent that works great for pm.

    Thanks. How about Bronners instead of dish washing liquid? I have heard that Ivory dish washing liquid is a better choice than say Dawn.

    it likely doesn't make a huge difference...I used Sunlight dish soap, heard of people using baby shampoo.... and I use olive oil instead vegetable oil

    HEPA filter....FTW

    Potassium Bicarbonate + bronners and water (or just get greencure)

    Outside I have used milk on squash with some success but I believe it needs to be baked with UV from the sun for a few hours after being sprayed.
