What Are the Sunlight Requirements for Exacum ?
Ideal Lighting: Partial sun
Exacum flourishes under bright, indirect sunlight for 12-14 hours daily, mimicking its native tropical conditions. Overexposure to direct sunlight can scorch leaves; aim for diffused light. Too little light, however, may lead to leggy growth and fewer flowers. For best results, rotate the plant for even light distribution. Use sheer curtains or a light filter to soften intense light. Grow lights can supplement on darker days, ensuring the light spectrum supports flowering.
