The environment in our houses dictates which plants will grow well and which ones will suffer. No other factor is more important in growing good plants than adequate light .
Plants differ greatly in their light requirements.
Those with brightly colored leaves such as coleus and croton , flowering plants and succulents grow best when placed in areas where they receive direct sunlight. Others, like ferns , philodendrons and many other foliage plants, grow well under indirect light. In a room poorly lighted by the sun, artificial lighting can be used to supplement or replace natural light. The incandescent bulb most commonly used in homes can be used to supplement natural light. Incandescent bulbs produce light primarily in the red and far-red regions of the visible light spectrum, but they are a poor source of blue light and therefore as a sole light source are not suitable for plant growth.
