| Dan - hydrogen peroxide you buy at the drug store will kill the mold without harming your roots. The next time it is time to water, pour peroxide over the mold, wait a few minutes and flush the pot with water. You can also apply cinnamon to the mold and it will kill it. Make sure you don't get the cinnamon on any growing tips of the roots.
I agree air circulation is the problem.
