I'm not sure if this will help you or not tweder, but I saw it in another forum and will post it here for you:

"I use my home-made sulfur burner on mold problems. while using the sulfur burner, all ventilation is turned off, of course, so I do the sulfur burner either the hour before the lights come on, or right when the lights go off - if done after, the fans are utilized to clean out the sulfur for a short bit once the hour is up, otherwise you will suffocate the plants if the sulfur is left in there overnight.

I just use the heating element from a coffee maker. the sulfur pellets burn in a tuna/salmon fish can."
