You’re probably wondering how these teeny-weeny lights can help in the growth of your plants even when there’s lack of sunlight. So for your sake, we’ll explain how LED (light-emitting diode) grow lights work.
Let’s begin with a fun fact: Plants can absorb more blue light than any other colors (such as light and green). Because of this, the ultraviolet rays are perfect for stimulating robust plant growth. Meanwhile, infrared rays are best for the germination and flowering phases.
LED grow lights, which have an extensive scope of wavelength options, are best for growing plants because you’ll need wavelengths that can be adjusted depending on the need of your plants living in the grow room.
These grow lights that emit ultraviolet (UV) rays are essential for the vegetative phase of plants because they can increase the cell division when your plants absorb the rays. When cell division is heightened, your plants can grow rapidly and trigger more produce. Meanwhile, LED lights that give off infrared rays (IR) are ideal for the flowering stage of the plants as they can be easily absorbed by the buds and apex of your plant which can cause them to bloom fast in greater amounts.
Remember that the growth of your plant depends on the following:
If you’re doubting the superiority of LED grow lights over HID lights, here’s a video that will change your mind:
Now that you’re convinced about the efficiency of LED grow lights, the next step is to determine how many watts you need.
To know the exact wattage for your grow area, you must first measure your area and count the plants you’ll need to cover.
If a square foot has one plant in it, then the ideal wattage is 25 watts per plant per square root. If you have two plants in a square foot, then the recommended wattage per square foot would be 50 watts, so on and so forth.
