I planted some D. brevifolia seeds a while ago, and only recently have they sprouted, and are growing fast. The largest ones have their first true leaf out. But, when potting, I used some pretty well washed perlite in the soil, and not even that much, maybe 70/30 peat/ perlite, less even. Anyways, it apparently wasn't washed enough, and algae and moss have started to grow, and I'm worried about the seedlings, because some slime is very close to them. Would I be able to transplant them w/o damaging them?
