| Fuzzy dirt = bad |
I had this same issue last year. I had done a little bit of reading last year and found that it's largely due to minimal to no air circulation. Because I have some tendency toward laziness when I can't immediately think of a good solution (in this case, the right fan), I did nothing last year.
This year, while I didn't plan ahead and get a good fan or two for my plants, I have done some research. From what I've read, a good solution to "curing" my problem (since I didn't head it off in the first place as I should have done) is to scrape away the top layer of affected soil and dispose of it. Today, I removed approx 3/8" of soil. Then you're supposed to apply some cinnamon to the soil. From what I've read, it's supposed to help deter further mold growth.
I guess I also need to look into getting some very small low-flow fans to attach to my wire shelving, too.
