Dinteranthus microspermus ssp. puberulus
Very, fine seeds (almost like dust) Some experience with sowing Lithops/Dinteranthus is recommended as they are a little more difficult then sowing normal Lithops.
Make sure that there is enough difference between day and night temperature during germination (preferably 8 degrees or more) This will greatly enhance germination.
Best sown at temperatures between 22- 34 *Celsius. Seeds take between 5 - 30 days to germinate (depending on conditions)
