Not your bong!!!! Those things are sacred!!!

Mark I studied several books etc and they all strongly recommend cutting off any diseased sections and removing them carefully from the grow room. Also as someone said...perhaps spraying down your walls at some point when your lights are on and plants removed for a few hours with the fungal spray.
Jorge's book also said (in a seperate section) that fungal spores do not grow well in a humidity of 40-50% so if you can even get down to 49 it would be good. I know you are doing the best you can.

I can't remember if I told you to click on the link in my sig to check out some good info on fungus....could be that I was just stoned and thinking about it instead.
