Calin---on looking some of those up in the data bases, I have found several are warm seeders.
Dictymolimon macronhabdos in Dr. Deno says 70º F and light for germination in 5 to 7 days.
Orostachys iwaerenge Dr. Deno supplement #1 says 70º F and light for germination in 4 to 6 days
Orostachys spinosa Tom Clothier says it is biennial 70º F germinates 3 to 10 days
Delosperma cooperi Tom Clothier says surface sow at 70º F for germination in 7 to 14 days
I'll try to find information on the others over the next few days.
