It likes high temperatures, but about 50% shade with full sun or partial sun in a ventilated spot is still recommended. Use a well-draining medium. Spring and autumn are the growing seasons, while the hot summer is a vigorous growing season when it can be watered fully. In winter, watering should be reduced or stopped.
The best time to pot up and transplant the plants is in late spring and early autumn, when the climate in most parts of the country is suitable (30°C during the day, 20°C at night); at the same time, there is a relatively large day-night temperature difference. According to the author's experience, a larger temperature difference can promote rooting and growth of Ariocarpus plants. Combined with a small greenhouse effect, the greenhouse temperature during the day can reach 40°C; at night, ventilation lowers it to 20°C, which is the most ideal environment for rooting and growth.
