LED Grow Light
Bringing nature indoors can be troublesome when rooms have little-to-no natural sunlight. Yet, houseplants can flourish indoors by using an LED grow light. While other indoor grow light options may be cheaper, like fluorescent lights, LED grow lights are the most energy-efficient and cost effective type of grow light for houseplants.
Most Effective Light Spectrum
Plants need the red and blue color rays in the light spectrum for growth, and have no need for the greens and yellows. The blue spectrum grows foliage and the reds grow flowers and fruits. An LED grow light emits only the blue and red color rays for maximum houseplant growth efficiency. Several LED grow light bulbs provide a balanced blue and red color spectrum, without the green or yellow rays, for maximum grow light efficiency. Some bulb models offer enhanced red color spectrums to benefit flowering plants.
Tops in Energy-Efficiency
Compared to other types of grow lights, an LED grow light uses as much as 30 percent less electricity. Energy efficient because they emit low heat, they also last for as long as 10 years which reduces waste and recycling efforts.
Best in Cost Effectiveness
Along with their longevity and energy efficiency, most LED grow light bulbs fit in any standard lamp or light socket. Since there is no need to purchase special lamps or cooling fans they are the cheapest of the grow light options for houseplants. A gooseneck style lamp provides the most flexibility for directing the bulb towards the houseplant, but most any lamp fixture will do.
Lighting Tips for Houseplants
- Houseplants should be placed 6 to 12 inches away from the grow bulb.
- Risers like plant stands can be used to lift up houseplant pots toward an inflexible lamp.
- Rooms with little to any outside lighting should have the LED grow light on for 16 to 18 hours per day for most houseplants.
- If the room receives some sunlight, adjust the grow light to 12 or 14 hours a day.
- Grow lights should be turned on and off during the same daytime period that natural sunlight would appear through a window.
- For best results, keep the lighting cycle consistent every day. Late weekend sleepers should consider using a properly grounded timer to control the lighting cycle.
- Keep the room temperature between 70 and 80 degrees for most houseplants, even when away during the day or on vacation.
- While all houseplants need monitoring for over watering, plants lighted with an LED grow light need even less water because the low heat level makes the plant less thirsty.
- Not all light LED light bulbs have both red and blue spectrum lights. Use only specially marked “LED grow light” bulbs.
While indoor gardeners mainly used fluorescent grow lights for the past several decades, the latest in LED grow light technology offers the most value in energy and cost savings. By combining both warm and cool LED diodes into a single LED grow light bulb, houseplants and even traditional outdoor plants, like vegetables and roses, can thrive indoors.
