When the water reservoir of your plant is empty, you can fill it until the water meter has risen to the maximum level (about 2 liters for a 30 cm pot and about 1.5 liters for a 27 cm pot). The amount of water that the plant consumes depends on temperature, humidity, location and season.
In the summer, your plant needs water on average twice a week. In winter this is an average of 1 per week to 1 time per 2 weeks.
It is important that you give Superfood plant food via the water once a week in both winter and summer.
