Lithops (Living Stones) has a recorded range of 8–36°C; Pencil Cactus is listed at 10–40°C. The recorded ranges overlap from 10 to 36°C. That overlap compares the draft entries; it is not proof that either plant will suit the spot.

Make the next care decision at the pot.
A comparison cannot set a watering date. Check moisture first: pot size, growing mix and current weather change how quickly a container dries. Record what you notice and decide when to check again.
Read the RHS guide to watering containers for general container advice, or use Plont’s plant observation checklist. The RHS source supports this general advice; it does not verify the species-specific draft values above.
