Strait up, used it ALL, and 2% milk, 1/9th ratio! And for late flowering (like the last 3 days) I soaked them like three to four times during lights out. SOAKED THEM! Once in milk, and then PH down w/ RO water. If you let them get moist they might get more spores, but i had really low RH, and 80/83 degree room when i did it. and it worked amazing. Really made them taste better too. And no PM showed up during the dry/cure. Also Spider mites HATE the cold, so with the RO water I would fill my pump with ice cubes, and i couldn't find one bugger the whole time i trimmed =)
used the H202... it comes back in day or two. but it will work instantly. Fizzing sound.... crazy shit.
But these home remedies only work to keep the spores of the PM down. The fungus lives on, stealing your nutes and eating your foliage. (or at least mine)
Keep fighting the good fight guys, I'm right there with you.

I'm on that one next! haven't been able to do it with the oils I am using. I read it is a big no no to mix the two within roughly 10 days.
Pirate, do you know if it works well to treat the room itself (walls, floors, ect...)? Or will the sulfur linger and cause problems when I bring the girls back in?

At what stage are your plants and how big?
I use Greencure. I use a regular spray bottle. I spray every day. I don't spray the whole plant every day, though I will pretty much soak it down every week or so. The first time, I'll soak them down good. Then I check every day, every plant. When I spot the white spots, i spray it. This keeps the reproduction down. No way could i dip the plants. maybe if they were small, but then a couple sprays and they're soaked, so why dip?
I like Greencure too.
Meltatox.
Now that ive used it, I believe

I read up on their label and found nothing that states it can be used on food plants, looks to be very effective for roses.

Just a big thanks to mark6699331, I've found the zone/penetrator combo the final key in getting rid of the pm.
I had a really bad breakout, and it came from a hempstar clone I got from a fiend who just accepts pm as a way of life. I always forget. The hempstar got about 2 weeks into flowering and devestated two flowering rooms (one hempstar in each).
Here are the steps I've taken, and it's been over a month since I've seen it:
1. I vaporized sulfur in both rooms 3 times in a week. 4.5 hours each session. I feel sulfur vapor affects the final product very little. Test smokers couldn't tell on this last batch, I had some 7 days from harvest.
2. Full cleaning. Like wipe everything in your grow room with bleach water.
3. I dumped a full box of baking soda on the floors of both rooms. If new spores fall to the ground they get fried before they reactivate.
4. I used mark6699331 recommended method of dipping whole plants. I just sprayed the more mature plants, but anything one week into flowering and the young ones in the veg room all got the full submarine treatment.
5. I burn sulfur every 10 days now, pull out the mature plants and just spray with zone/penetrator.
6. I dip the clones and young plants every 10 days.
I've done this for a couple months now and haven't seen a hint of pm. Thanks to mark6699331, I've tried so many things over the years and I think the zone/penetrator is final step to kill it off in the young plants where you can't see it. The sulfur/baking soda on floor keeps it from reproducing in flowering rooms. I can't believe that this shit might finally be gone.

Great thread! I got pm recently from some pre '98 clones. It has spread like crazy. Never had it up to this point. I have been aggressive with ventilation and kept it in check, but I still see new outbreaks daily. Some of my stock seemed to pick it up quickly, while some of the strains aren't effected at all.
I got a clone once before with pm on it, but must have gotten control of the pm while in quarentine as it never amounted to anything. It was also a bubba kush.

I would only dunk during veg./early flower or at least with the oils. However, if you do, rinse...no... SOAK! your girls in rotation of 2%milk at a 10-20% ratio, and then rinse with PH down and water later on. Do it couple days in a row, spraying once with milk and then once of twice with water during lights off. The key is to keep them soaked from the first spray until the lights are coming back on (so that there is little to no "damp" time). Great way to battle the mold, and take off any type of fungicide you used. I was going to try to maybe go with a smaller plant count this time (well a lot, but what ever you can handle), and treating them good during veg., so little will need to hopefully happen during flower.
They don't say anything about dunks/handhelds, because they are for larger crop/grove application normally. It does instantly emulsify on contact with water, and they do say that "the only way it will help mildew is if there is TOTAL coverage." I used it for mites, and haven't seen them come back... yet...
I wouldn't foliar with it, it does save a lot, but didn't fully work for me at all. Dunks with a air stone to agitate is total insurance, but time consuming.
I'm right there with you buddy! keep up the good fight! I hope this helps a little, let us know how it goes! I'm going to try the neem as a soil drench, it didn't work well for me either, but i'll see how this application works.

I'm growing my first crop here and one of my plants has some bad powder mold. The plant is doing great other than that but this needs to get under control. I sprayed it down thoroughly with a solution of higher Ph water and baking soda. Going to repeat that today.
This is my first treatment because I don't have any other on hand. If this doesn't work I plan to get some Dutchmaster Zone and Penetrator. Great thread thanks everyone.
