Direct Sunlight (Full Sun)
Knotty Pearlwort thrives best in direct sunlight or full sun meaning that it loves at least 6-8 hours of bright direct light.
If growing outdoors, you will want to plant Knotty Pearlwort in an area that receives sunlight throughout the day. If growing indoors, place near a South-facing window for ideal conditions. South-facing windows receive the most amount of direct light everyday.
