Fungus Snow

I've had lots of mold in my pots before, but it never looked like snow like this.

Fungus in D. capensis seedling pot.

I don't know if my sulfur-based fungicide is only preventative, but I guess I'll give these moldy pots the ol' scraperoo with a toothpick and then spray them a little. It's almost like these plants are made to be kept indoors. I need to look into getting smaller fans that I can put on the lower shelf instead of one kind of aiming down between the lights.
