I'd suggest you stop watering them & just leave them alone. When you see new growth, you'll know the roots have taken. Don't lift them up to check, you'll break the tiny new roots you're trying to grow.

I had one of them years ago. It's in the night blooming Cerus (sp?) family. They get a large, beautiful white flower that blooms after dark. It gradually opens up. Then it starts fade at first light. Mine got 3 feet tall before it bloomed. Mine only bloomed once a year. I've seen them growing outside in 9a Florida against the side of the house. They must have been decades old. Full of about a hundred blooms that filled on whole side of the house.

Be careful not to overwater. Make sure they get plenty of light. In the first pic, the soil looks very dark. Is it wet? As for the last one, when you water it, take it out of the outer pot and let it completely drip off dry before putting it back (like an hour or more). Nice plants. Nice Mom!

Sempervivums are very difficult to ID, there are more than 50 species and thousands cultivars, with many looking very similar. Exact name of the cultivar really doesn't matter that much as far as their needs: they are really same. When plant is not healthy, or grown under not-so-good conditions, they may, and often do, different than they should and that's another problem to ID it correctly. Kirby I don't see you mentioning your general location or growing zone? Sempervivums are very hardy plants, most of them will overwinter outdoors, under the snow, in z4 and many even lower. So unless you are in colder location, they could and should be grown outdoors. Proper pots are much more important than one may think. I would encourage you to repot plants that are in containers that do not have drainage holes. You don't even need to buy pots - plastic containers from cottage cheese or yogurt will work as long as you poke holes in it - a thin nail or straight pin works very well. Many small holes around bottom are great. Use opaque containers, as see-through will encourage growth of algae (more of a aesthetic problem, it will not kill your plants). I hope you do not think that we are preaching to you - all members here are quite enthusiastic about succulents; everyone that posted wanted to offer some helpful tips. We do get carried away - as soon as any of us see a problem, we comment even if you didn't ask about it (potting mix and drainage holes in this case...). It is all meant well and to help - otherwise none of us would waste time on reading and replaying :)
