The solution is very simple. The first appearance is in grass about an inch tall. A fine web that if not treated grows up and more concentrated.
The correction is putting the tray on the floor and spraying with high pressure; letting the water flow out to where is doesn't leak out on the racks.
What is really being done is nature's correction when hard rain flushes the mold into the ground. I have never had it reoccur after one treatment.
