    I have the other thread out there asking how. Now I know. History. I have an original White Widow, verified by experts over my head. I did the cardinal mistake of taking a plant from someone else and not putting it in quarantine. The mildewcides that kill PM are bad for consumption, especially once burned/heated.

    Well I went through 3 cloning cycles just hammering the plants with Eagle 20. Just the clones were moved to another sterile grow area and they were cloned, grown, sprayed with E20 and about a week later cuttings taken and cloned. As stated 3 full grow cycles in veg were done. Meanwhile the other garden was allowed to grow out and finish (I do a perpetual method) The grow room was then majorly cleaned sprayed with a bleach water concoction and new fans and filters installed. All pots were washed in bleach.

    Tho not completely done with the first new flower cycle (5 weeks in) there is no sign of PM on anything in the flower room. The one in there is 3 months since Eagle 20 of the mother. It should be safe to consume once completed.

    Nope, it came back in the Widow, showed in the last week in Willie Nelson, a new plant for the garden. Soooo. No luck, but trying again with a different product that goes into the soil; active ingredient is myclobutanil. (F-stop granular). Systemic treatment over foliar

    Howzit WW?

    Been using food grade citric acid spray with limited success.
    It's not perfect and needs to be applied weekly.
    So, there remain a few patches of PM.
    Not a big problem. As soon as I start to harvest,
    the branches go directly into a large jar, half filled with 3% H2O2

    Then, I shake it like a red-headed stepchild. :)

    Seriously, if the peroxide is room temperature, there's no need to be gentle.
    I have taken macro photos before, and after with increasing violence up to as hard a shake as I could muster. The trichomes were all still capped with resin glands but the PM was all but gone.
    A microscope shows traces but the taste and scent are clean.
    I then "whip" off as much moisture as I can and hang them outdoors to dry in the shade, in the A. M..

    By evening they are dry enough for the indoor drying cabinet.
    This is recommended for WPM only.
    Any other kine mold should be discarded.

    Fine Weez, hope you are well. Using Nuke'em during the last few weeks to prevent spores. It is essentially just citric acid. Just gonna have to deal with it.
