Using a humidifier or maintaining the terrarium's closed environment will help achieve the necessary moisture levels.

Temperature: This plant prefers warm temperatures between 18°C and 24°C. It is sensitive to cold and should be kept away from temperatures below 15°C. Maintaining a stable, warm environment will promote healthy growth and vibrant foliage.
