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

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

yes dont use neem oil with a sulfur burner
