Hey Nikki, and
to the site and to the forum!
My advice won't be
nearly as good as others', but the bottom leaves of your semps will begin to rot much faster if you don't put something under them to protect them. When I got my first sempervivums three years ago, it was recommended to me (on this site) to put chicken grit underneath the plants so that they wouldn't rot. I didn't have chicken grit on hand, so I used perlite instead, and it really did help a lot.
Your semps are beautiful, though, so I'll keep my fingers crossed for you that they stay that way!
