Neli, only time will tell which ones will do well for your growing conditions. Meanwhile it looks like you are doing a very good job of figuring out what will work in your area. The new plants are looking great. All ready I see them responding the your excellent care.
Just keep on doing what is working for you. And please keep us updated on how they are doing. It will be valuable information to those growing in similar conditions.
Most of us do not live in alpine areas, that is where sempervivum come from originally. Each of us has to figure out what works for our individual unique growing conditions. That said, I still find an occasional semp that won't take as much sun as some of the others in my collection. Same for our rainy season, some fly through with no damage, others struggle and rot.
