LEDs are an important component of the indoor growing industry. But still a large segment of the hydroponic gardening community does not know exactly how to make LEDs work effectively for their garden. LED can be used a supplemental lighting device or a primary lighting device based on your needs.
LEDs designed to boost the amount of red light in your hydroponic grow room and promote larger fruit and flowers and heighten the ripening response in photosensitive plants. These days even ultraviolet LEDs which emit UV-B rays are gaining popularity. As a grower you can use this to enhance essential oil production and promote stronger structural integrity in their plants.
Use of LED as a primary source of light in your hydroponic garden is becoming prevalent with advance in technology. Lighting fixtures capable of replacing HID or fluorescents as the primary lighting source for an indoor garden are available these days. In the past, LED grow lights were used for primary lighting created spindly plants unable to produce large fruit or flower sets because the LEDs used were not powerful enough to penetrate the plant canopy. The most recent horticultural LED fixtures utilize high wattage (2- or 3-watt bulbs) to enhance light penetration.
LED lighting devices produce much less radiant heat than HIDs. So the grower might need to externally heat the grow room. Another way to maximize performance in an LED grow room is by supplementing metabolic stimulators. Metabolic stimulators increase the rate at which plant functions occur, which increases growth rates and yields. You will also need to pay attention to ensure that there is adequate air circulation within the grow room. Use of oscillating fans is probably the best way to ensure sufficient air -movement in between plants while using LED in your hydroponic grow rooms.
