Sand, and loam, with some sphagnum moss or coir (coconut fiber/dust) make a good mix for germinating cacti and similar seeds. The mix needs to be free-draining, and to be slightly water retentive. Surface sow the seeds and just cover with sand. Start germinating the seeds in shady (dark), humid conditions. As the seeds start to germinate, increase the light and decrease the humidity.
