Mammillaria has a recorded range of 8–38°C; Moon Cactus is listed at 10–35°C. The recorded ranges overlap from 10 to 35°C. That overlap compares the draft entries; it is not proof that either plant will suit the spot.
Mammillaria is marked easy, compared with moderate for Moon Cactus. Treat that as a planning estimate, then ask which care tasks each plant needs in your conditions.
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.
