Ok, thanks for elaborating. Only change was to a different place so the spores got picked up there. Is it too late to do a bleach wash of the entire place with a pressure washer or something?

I would also consider one of those propane space heaters......not only will it warm, but increase carbon monoxide and carbon dioxide....a safety issue for peoples if kept closed in. I dont' know about the sulphur burners but I do know the propane heater will not injure plants that have had neem....of course it is not directed right at the plants, just in the intake air space....sorta preheating.

Will follow this, interesting to say the least.
