Hello Corel, and welcome to the gardening forum!
String of Hearts like a lot of bright light, but not direct outdoor sun.
They are somewhat succulent, and should almost dry out between waterings.
It's in a fast draining pot, with fast draining soil. When you do water, soak it well until water runs out the bottom, then let it get pretty dry before watering again.
Don't repot it for at least a year, it's just getting established and is busy growing roots.
They like warm temps, it will be happiest at 80+. Don't let it go below about 60 degrees.
Did you acquire this plant in Arizona? I think I might be the one who started it from cuttings. I'm happy to see it doing well, and assume you had a safe trip. Does this look like the mother plant ?
