I have done this. An incandescent bulb inside the blankets gives about 8 degrees under them.
The good news is that it is 100 degrees and no rain! Sprayed 3 times with sulfur and the new growth is almost all spot free. Some plants seem to be more resistant, the spots on them don't seem to be growing and killing the leaves. THings are starting to kick into flower here, so we will see how far the buds get to go, before they have to be harvested.

Sounds good. Did you ever dust w/sulfur?

I love killer hogs. Malcome has inspired a lot of my cooking, his rub is awesome too!
Yes, I sprayed 3 times, so far.
Last time it took 4 gallons to do the job.

I meant dust w/sulfur as opposed to spraying.
Nope. Never have done that. My sulfur treatment is contained in a liquid solution. I use it in conjunction with liquid soap so it will adhere better to the leaves. Seems to me the dust would not stay on the plant as well, especially the under sides of the leaves.

Thanks. I've dusted with copper but not sulfur. Didn't realize it was necessary to get undersides of leaves. I spray when I have to but hate spraying. I need a new sprayer.
I won't use copper personally, as it is not something I want in contact with anything I ingest, but I understand it is very effective at treating fungus issues. I just use a 2 gallon hand pump sprayer from Lowes. The latest one I bought actually seems to work really well! I also use it to spray Zerotol, when we get into flower and PM starts to appear.

The last few years I have been doing a sulphur spray just before flowering in early August. I haven’t had any PM issues since I’ve started doing this. I would never use it during flower but it effectively gets rid of any potential PM issues that may be just starting. Trying to manage a PM outbreak during flower is a real pain.

I figured copper, like sulfur, would not really be in something you ingest as long as you don't use it during flower.
I just learned this, myself. From another source. "Cannabis Is a Bioaccumulator Plant, Which Means It Takes in Everything From the Soil or Growing Medium – Good and Bad. It's such an accumulator that cannabis has been used at Chernobyl to absorb radiation from the soil, decreasing radiation volume in the ground."
Late in flower, when it gets rainy and cooler, is when I typically see PM in OKlahoma. I learned about Zerotol from some commercial Colorado growers, what a game changer for outdoor growing! It can be sprayed all the way to harvest and it wipes out PM. It breaks down to oxygen and water, so no residue. I have found that when outdoor plants get near the end, everything attacks them, as they weaken from old age. Zerotol does no damage to flowers when used as prescribed. Used it for 4 years now. I won't use sulfur in flower either. What region are you in?

The article says from the soil, not foliar. Just the same I'll seek alternatives to be safe. I've used copper only a year or two so I'm not really worried about buildup at this point. In my mind the article inderscores the importance of growing in living soil. As always, appreciate the info.
I am all about living soil as well! The thing is, anything you spray or dust on a plant, will land on the soil around it. I know a lot of commercial grows in Oklahoma have failed testing for heavy metals. One grow used sand scraped out of the river bottom, don't know which one. All our rivers have , sadly, had contamination from our 100 plus years of oil production. Like you suggest, at what point does the build up become an issue for our health?

Sure. But occasional foliar applications shouldn't contaminate soil imo. Even though copper is a necessary trace mineral, I'd rather not use it at all, let alone continuously. Obviously, too much sulfur isn't good either. Anyway, we're in agreement. I'm just learning what I can and doing what I can to safely battle septoria and other fungus in my grow.
