I was transplanting seedlings of chives and parsley and noticed white fuzzy specks clustered in the soil. Because it exists in both sets of seedlings - neither of which started with this fuzzy stuff - I imagine it is something in the soil or it is a mold they both got.
These seedlings grew indoors under a grow light by a window, occasionally with a heating mat on beneath them. The soil was kept pretty moist - rarely fully wet or dry - and to keep it that way took frequent watering since the grow light would dry the soil of these small seedlings daily.
What are these white fuzzy specks? My guess is some kind of fungal activity, but I'm not sure if it's bad. These seedlings have been growing well. I plan to transplant some of these to the garden soon, or bigger pots, or keep in their pots - any precautions or steps I should take in light of this fuzz's appearance?
