    Pathos Saver!!!!
    I had a my pathos covered in the fuzzy/powdery white mold. I tried using the baking soda and dish soap idea several times and it seemed to be only a temporary fix. Also I noticed it starting to spread to my other plants. With the frustration I was feeling with trying to get rid of the mold this stuff worked like a miracle. I would 100% recommend for pathos. I also want to mention I waited a couple weeks to see the results before posting my review.

    Reviewed in the United States on March 10, 2023
    Size: 24 oz, Ready to UseVerified Purchase
    First time grower, I went all out with the bells and whistles. Tent, controllers, multiple fans, high end light setup etc. Though most of vegetation was completely fine, towards the end I ran into issues with powdery mildew showing up. After a LOT of research, it was a demon of my own making. Plants too close together, too many for the space, too high humidity, not enough airflow, I basically did all the wrong stuff. After discovering some SMALL spots on my leaves I panicked, researched, and resolved the environmental issues. It's now at proper humidity and temperature with adequate airflow and a carbon filter. Since doing that alone won't kill mildew, I started looking into options to "stop the spread". I tried the home remedies with neem oil, dish soap, milk, it just seemed to come right back. I decided to look for something a bit more focused for my issue and came across this organic solution. It works extremely well. If you follow the directions, it is very self explanatory. It's great as a preventative too, even if you don't have the powdery mildew issue currently. I bought the handheld spray version first as a tester, great way to lead into it. It worked so well I got the concentrate to use continuously, I use the original spray bottle and refill it. It works out to 1.8tsp of concentrate to refill that original spray bottle, so it will last a really REALLY long time for the home user at that rate. Overall, it will now be part of my standard arsenal for indoor growing.

    When i started seeing powdery mildew, my tent was at 80 degrees with 50-65% humidity when I started noticing issues, though it was that way due to multiple variables that have been resolved. Keep in mind, this product works great but is not a super cure. You MUST resolve environmental issues to keep it from coming right back, this just kills it on the spot

    I used a quality electric micro mister. Along with adjusting the environment the Growers alley held back and stopped PM. I used just less than half strength with distilled waters hours prior to light cycle. Fans were turned on 30 min prior to dissipate any remaining water residue prior to the lights. A few leaves here and there got affected mainly ones that were lower and in a denser area of leafs. Plants made it all the way through flowering. Prize winners. So yes, for me using proper methods going lighter. I didn't use a double spray method until 3rd spray. Total of 4 sprays over 3 weeks.

    I tried using Grower's Ally Fungicide for Plants, a plant fungicide treatment that claims to control powdery mildew, fungus, and more. While my experience with it was somewhat mixed, I can say that it "kinda" worked.

    Although the fungicide showed some effectiveness in managing plant diseases, it didn't entirely eliminate the issues I was facing. There were still signs of powdery mildew and fungus, albeit to a lesser extent. While it may have provided some control, it fell short of delivering the complete eradication I had hoped for.

    Given my experience, I would recommend considering alternative options or seeking advice from experienced cultivators to find a more effective plant fungicide treatment. Keep in mind that different plant varieties and environmental factors can affect the performance of fungicides.

    I purchased this for several plants that had powdery mildew on them. I sprayed them one day according to the instructions and the next day, they were dead. I have a green thumb and had brought these plants up from babies only to be killed by something that was advertised to help them. Only use this product if you want your plants dead.
