Indoor gardeners often wonder if they can simply use regular light bulbs as grow lights. Some people might even swear that their plants do better when placed under a lamp during winter. You technically can use regular light bulbs as grow lights for your indoor plants, but their are some caveats. The standard light bulbs found in most homes omit an orange or yellow light. This light can promote some degree of photosynthesis but for leaf development, flower blooming or fruit and vegetable production, a full spectrum grow light is essential. The standard, incandescent light bulbs also generate heat which can be detrimental to your plants if positioned too close to the foliage. Grow lights are designed to produce as little heat as possible or have built-in mechanisms to dissipate the heat. LED grow lights are a popular choice due to their low heat production and energy efficiency.
