Powdery Mildew and Spider mites in the grow room. How to restart the system

[Jimski]

Look into a sulfur burner.

Add thumb for sulfur burner. Outside only. I have used this on outside crops and recently did my tent outside. When used on outside crops it leaves a residue on plants that zero bugs can stand. Great till the next rain.
This is the nuclear option for pest and pathogen control.

Is there any residue or after smell from a sulfur burner?

Yes but it rinses off. brown to silver coating depending on disk or pebbles in the burner.
And yes it smells like sulpher......

Doesn't wettable sulfur do the same thing?

No they can be used safely indoor no need to burn outdoors just use the powder to dust plants I would never use any kind of sulfur on plants indoor but bombing rooms in-between grows is fine an safe to do.

Yes but its tuff to get the spray into tiny cracks where mites hide the burner will get into anything in the room lights an electronics must be removed before burning sulfur.

I just lost a beautiful plant because I had to go out of town for three days and when I got back it was covered with PM. Chopped it and tossed it. I hosed the entire grow tent down with H2O2 3%, 1.25 bottles in almost two gallons of water. I feel your pain.

Micronised sulphur isn't the same as burning sulphur, burning sulphur produces sulphur dioxide gas that's deadly to insects.

Permethrin smoke bombs are another option Permethrin kills eggs and adults and they're cheap circa $4 and ready to burn.

Once these afflictions take over how do you go about restarting your grow room? I have killed all the plants and moved out anything I can. What other steps are required to get a clean room up and running again? thank you for your comments

Room or tent.

Whatever cleaning regiment you chose make extra attention to anything that moves air. You may have PM spores in ducting, or with old school boxed up aircooled heatsinked led lights it would go into the light and come back next grow unless you take it apart and clean properly.

Edit: oh yes, forgot: those meshy hoods that keeps your fingers out of oscillating fans need cleaning down aswell, depending on what your setup is like.
