Re-potted the Sempervivium (Hauswurz) today into a balcony box to give them some more room. The boxes don't always have drainage holes so I drilled some. The soil mix for these are Seramis Kakteen for the lowest layer, a mix of sandy succulent soil and Lechuza-Pon (I ran out of Seramis) for the center and a small layer of Lechuza-Pon on the top. I didn't remove all of the older soil to keep most of it together but loosened the roots a bit.
