The mold is probably from the seeds, not the basalt, but is is a sign of active microbes in your soil. I've never looked at these molds as anything more than innocuous and I just turn the soil over when I see it (usually from alfalfa meal added). That being said, I know there's all the Probiotic cannabis growers that are all about it and it seems to work well for them. I'm more amazed than anything by all the ways we can grow this plant.I did order the basalt, thanks KIS. I have to post a pic of a pot I just made up and dropped a seed in. I had a like bit of malted barley bits left over in a bowl so I sprinkled 6 or 8 not fully ground seeds on top and a tiny bit of dust. I thought this was cool
