anyone use a sulfur burner??

Anyone have experience using a sulfur burner, for prevention of gray mold.

Always get some about week 7.

Nothing about it in grow FAQs.

I've used mine for powdery mildew, and it's the only thing that will completely rid my grow of that stuff.

I run mine during dark hours for 3-4 hours, and the powdery mildew is dead.

I'm planning on running it for 15 min. 5x7x8 Do you think I should run it longer?

Bought it today.

No more singing the botrytis blues.

Thank for answering, I wasn't holding my breath anyone would answer .

I guess it depends on where you position the sulfur cup. I have mine suspended above and not touching the heating element. That way, it takes at least 30 minutes for the sulfur to melt, and start to fill the air.

I don't really know, I stay out of there when it's on, I just leave it for 3-4 hours, and make sure the cup doesn't go empty. Also, an oven glove is a handy thing.

Thanks, I'll figure it out from here, a little experimentation will get it. Got the basic guidelines.

FIY if you buy one at a store, open it up. Mine had a damaged heating element. Shake it like a light bulb and listen.

I know this post is very old..... but I've heard that if you've sprayed your plants with Neem Oil in the past week, and then toss in a sulfur burner, that it will burn your plants. Is that true??
