Starting lithops seeds--did I do right?
I started some lithops seed about a month ago, using a combo of miracle gro cactus medium mixed 50/50 with perlite, hydroton on the bottom of a clay pot. The medium was damp when the seeds were surface-sown, now I'm wishing I had covered them with ~2mm of stone dust to keep them better rooted and upright. They only get misted, and not watered, covered with translucent plastic most of the time, but I'm letting them dry very slightly between mistings. Am I on the right track? I only got 50% germination after 3 weeks, but apparently no damping off.
Also, are individual plants/flowers self-fertile?
