Great new batch of lithops Alain. You can never have too many lithops! :) My favorite, and it is really hard to pick a favorite, is the dark red L. aucampiae. The bromfieldii 'Welgevonden" would be my second choice. As I said, they all great. How many pots of lithops to you have in the greenhouse? An educated estimate would be fine. :) Thanks for sharing.
I agree you can never have too many Lithops. The number of pots of Lithops I have runs into hundreds. I have split up some old cactus which has given me some room for quite a few Lthops in 5cm pots.
