These can be purchased or use aluminum foil to focus light. You can increase the amount of light a plant receives even with a low output bulb by using a reflector. Medium light plants, such as tropical rainforest specimens, need around 250-1,000 foot candles (2500-10,000 lux), while high light plants need over 1,000 foot candles (10,000 lux). Every plant needs a different amount of foot candles. This measurement indicates the amount of light given off a foot (.30 m.) away. Light for growing plants is measured in foot candles. Determining Lighting Requirements IndoorsĪ good light meter can help you determine how bright you need to make the light system. They are also more energy efficient and the light produced is readily used by the plant. In fact, new T5 lighting systems produce less heat than the old bulbs and can be placed closer to the plant without worrying about burning foliage. Modern fluorescents, however, have increased the lumen output, come in compact bulbs and last longer than their predecessors. Therefore, the bulbs are not ideal for fruiting and flowering plants. They fell out of favor because they don’t last very long, are delicate, bulky, and don’t provide a high lumen intensity. LEDs depends upon the light requirements indoors that your particular crop or plant needs.įluorescent lights were once the “go to” source of plant lamps. Fluorescent lights don’t last as long as LEDs but are easy to find and install. They are an excellent source of light for young seedlings and plant starts. Modern plant lighting has focused on the LED sources of light, but fluorescent lights are still widely available and easy to use. Standard indoor lights do little to influence photosynthesis, while using fluorescent lighting placed closely to the top of the plants can help drive this important plant process. Using fluorescent garden lights to enhance plant growth allows you to grow a host of plants in an interior space. The right kind of grow lights can make all the difference in how your plants perform.
