Sulfer vapes are pretty much the real-world treatment of choice for above-media fungal pathogens.

Hey Razza- do you have a problem already, or is this prophylactic?

If yer using it on rotation to prevent infection, you can use it infrequently- maybe every two weeks.

Application has to be maintained long enough to get good penetration- osc fans will speed things greatly. Pretty much as soon as everything has been vaped, you can extinguish and blow off.

Remember, those things are sized for greenhouses- gazillions of cubic feet. It'll do even a good sized room in minutes.

Seriously, I'd think that even 15 minutes might be over-kill.

Have fun- those are a wicked good time.
