Sulfur vaporizers

Anyone have experience with these??? Is it ok to use these on young plants ( babies rooted a week ago been under MH for 4-5 days)

Are they flamable if the spill/boil over??? Does the vaporizer sulfur cure the plant after mutipul treatments??

My daytime humidity is 20-40%, temp 75-80*F and my night time is 50-60% temp 65-70*F (thats with a dehumidifier) Washington is normally 90-100% humidity

I never had WM before.... the Grand Daddy Purple strain was the cause it...after 12 days of 12/12 I notice3d it..... and now its starting to spread
