How to grow clivia well on a windowsill indoors

How do you grow clivia on an indoor windowsill?
①Control the light. If the room faces south, full-day light is fine in spring, autumn and winter, but in summer you must reduce the light hours; on sunny days 4-5 hours of light in the morning and evening is enough, and at noon move the pot indoors.
②Increase humidity. Windowsills in ordinary homes tend to be rather dry, and the humidity is not enough, which is bad for clivia growth. You can spray water around the pot 1-2 times a day, and if conditions allow, place the pot on top of a fish tank or water trough to raise the ambient humidity.
③Pay attention to ventilation. Except in winter, open the windows often for ventilation in spring, summer and autumn; ventilate for no less than 2 hours in spring and autumn, and no less than 4 hours in summer.
④Maintain a temperature difference. For clivia's metabolism to proceed normally, a certain day-night temperature difference (6-10°C) needs to be maintained; this promotes plant growth and flowering on schedule.
