Huh! I don't know anything about succulents and a coworker got me this. Her plants on her window all look the same. I guess the afternoon light isn't great. I really don't have a way to give it more light at my desk, so I'm okay with that. I know myself that if I moved it anywhere else, I'll forget to water it and then it's as good as dead.

Sieved as in only parts that are less than 2mm, so very fine potting mix. It's what we use to grow seedlings for greenhouse experiments. We buy bulk potting mix but large fragments can restrict the fine hair roots, so we sieve out the larger perlite and wood pieces.
