Indoor Lighting Factors to Consider:
colors of the lighting spectrum


Light Color – Sunshine has a full spectrum of light wavelengths which plants use for photosynthesis, red and blue are the most important. Blue helps young plants build growth and full foliage. The wavelengths with red promote fruits and flowers.

Light Intensity – Plants need light to do well and thrive, but some plants need more than others. Flowering plants generally need more light than foliage plants.

Light Duration -Just as plant need light to grow, like people they also require rest. Plants are divided into three groups.

Short day plants – requiring less than 12 hours of light per day. These plants are often “forced” to flower by making their lighting duration very short to set buds and flower – Christmas cactus for example.

Long day plants – require 14 to 18 hours of light per day. Vegetables and garden plants stretch when they don’t get enough light.

Neutral plants – require 8-12 hours of lighting per day all through the year – coleus and many foliage houseplants fall into this group.
