LED grow lights are a great option, as they emit the right spectrum of light for your succulent plant growth. Place the lights about 6–12 inches above these delicate pearl plants and keep them on for around 12–14 hours a day. This will help mimic natural sunlight and keep your string of pearls happy.

However, be cautious of exposing it to direct sun for extended periods, as it can scorch the delicate leaves.
