Light Level Definitions
Direct light means unfiltered sunlight hitting leaves directly - typically within 2 feet of a south-facing window. Bright indirect light is strong but filtered, like near an east window or a few feet from a south window. Medium light reaches areas 5-8 feet from bright windows. Low light is found in north-facing rooms or far from windows.
Signs of Light Problems
Too little light causes leggy growth, small leaves, and loss of variegation. Plants may lean dramatically toward light sources. Too much light causes sunburn - bleached, brown, or crispy patches on leaves, especially on the side facing the light source.
Window Orientation
South-facing windows provide the most light (best for succulents, cacti). East windows offer gentle morning light (perfect for ferns, tropical plants). West windows have intense afternoon light. North windows provide consistent low light (ideal for low-light tolerant plants).
Supplemental Lighting
Grow lights can help in darker spaces. Look for full-spectrum LED lights that provide both red and blue wavelengths. Keep lights 6-12 inches from plants and run them 10-14 hours daily. Many stylish grow light options now blend seamlessly with home decor.
