Ozone can kill mold. If you have an ozone generator try that it MAY help.

I know its not good for living plants but now that you have harvested it is different.

put an ozone generator in a sealed bag or Rubbermaid tub with some of the mold pot and see what happens. About 4 hours should be enough but I am just guessing. I paid a company a shit load of money a few years ago to kill mold in my house and they brought in Ozone generators and ran them for about 4 hours. They said they killed off all the mold (no proof that was extra) but I did research and found out that is one way to kill mold. I still felt ripped off but such as life it made my wife feel better.
