My first experience growing non-lithops Mesembs from seed was growing Delosperma and Frithia. I don't have much room here but just couldn't resist sowing some more. Looks like I'll be posting a lot of baby pictures, bear with me. :) Here are the young Titanopsis calcarea seedlings from before (own seeds). It's fun watching them - so tiny and already all the cute warts are visible.
At the moment T. primosii is germinating, more pics soon.
