Alright, I found this little guy uprooted in the middle of winter and rescued it. It's definitely alive (well, the chick died and there haven't been any more in the year I've had it), but I have no idea what kind it is.
Also, I've heard a bit less sun was alright but it's definitely etiolated? Any suggestions?
Thank you so much !!

Wekl i know it's a sempervivum and usually needs to be outside. Whether in a pot or in the garden. Loves sun, dry, gritty soil.

Agree with Calin, sempervivums are very hardy and need to be outside. They will take a lot of sun.
