DebsB,
I have some sempervivum indoors just because I enjoy looking at them when all of my others are covered with snow.
I like to keep on hand a small bag of each of these mixes and combine them. It depends largely on what's available to you as to which you might use. You don't need all of these, just try to get something that's fast-draining.
Cactus mix
Orchid mix
Sharp sand
Chicken grit
Gravel or small rocks
I like to add the gravel or small rocks to the topmost layer. It seems to help keep the crowns drier, plus, it looks pretty.
For watering, I'll generally just mist-spray them unless they start getting dry looking leaves - then, I'll pour a bit around each plant. (I think I've only had to do this twice or so in the past six months.)
Definitely try to get your plant more light - not too much direct sun all at once, but let it acclimate gradually to increasingly higher light levels.
Hope this helps, and
to ATP!
