I have ordered some seeds from both Lithops and Conophylum genus' of succlents and was wondering if anyone here would be willing to share some of their success stories. I have tried placing them in pots with a seed mix that I found online and have them setup in a pot with a ziplock bag and so far I have not seen any growth popping up from the soil mix.

I am very interested in both of these genus' of plants and am looking for any tips that might help me out.
