What differs for your space?
Both entries list full sun (6+ hours). Light alone does not distinguish this pair in the catalog; compare the temperature and care-level entries below.
Golden Barrel Cactus has a recorded range of 8–40°C; Mammillaria is listed at 8–38°C. The recorded ranges overlap from 8 to 38°C. That overlap compares the draft entries; it is not proof that either plant will suit the spot.
Golden Barrel Cactus is marked moderate, compared with easy for Mammillaria. 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.
