Problems with powder mildew help?

Travis420 · Dec 14, 2021

Does anyone have any good advice of what to do to kill powder mildew in the 5th week of flower? Been spraying with lost coast plant therapy for now. Thanks

If you have the ability to vaporize sulphur, that's what I would do.
If not, I've heard good things about purecrop1, though I've never used it personally.

I got through a flower run with PM using a sulphur burner, short 20-30min burns every night up until 10 days before chop. Didn't impact the finished product negatively, if anything it was an extra good tasting crop. Sulphur is one of the primary nutrients used for terpene production.

Awesome thank you. Do you know how I would use it in a closed room set up? How long would I have to wait to go back in my room?

Ideally you want to vent it out after the burn somehow. But if doing Short burns it should be fine. Just rip a 20 min burn every night in the second hr of dark.

Just know, if you use LED sulphur burner can damage some LED lights. 301-H diodes are safe for sulphur and some boards and bars are silicone coated, and those can be safe. It's really more something to use in an HID setup.

When it comes to powdery mildew, I usually use baking soda. In a quart of water, I put 1 teaspoon baking soda. Because the solution only kills the fungus that it comes into touch with, spray the plants vigorously. Another home remedy that works is milk spray. I didn't utilize it, though. I, too, have a similar problem, and a friend who works in a marijuana dispensary suggested this solution to me. As you can imagine, they have to deal with stuff like this all the time, that’s why I asked.

Hydroponic stores usually sell both sulphur burners, and pure sulphur prills.

Crank your room temp up to 95F plus and keep it there for a week.

Nah just keep on top of watering and they will be fine. high temps kills off PM, hella better then jackin around with sulfur burners and sprays. Which a lot of the sprays do nothing other then keep it at bay, it’s still there.
