Like the names imply, LED grow lights can either be your plants primary source of light, or they can be used to supplement the lights you’re already using.
Your primary lights will have the most significant impact on your plants. Therefore, you’ll want to ensure these lights offer plenty of strength to stimulate plant growth.
At the lower end of the scale you’ll see 210w LED grow lights that offer peak PPFD at 455 or higher, which is good for a single flowering/fruiting plant.
On the higher end, you have 1000w lights that pump out over 1700 PPFD, which is more than enough for 2 to 3 mature fruiting plants per light.
As far as their spectral availability, primary lights come with an array of multi-colored spectrums, as well as white color temperatures. Some primary lights offer 1 spectrum, while other lights have the ability to adjust spectrums. The Kind LED K5 Series XL750, for example, has programmable wavelengths to offer plants all-red, all-blue, all-white, or a mix of wavelengths depending on the stage of growth. No matter what spectrum of light you give your plants, make sure your primary light has all the wavelengths they need.
Supplemental lights, on the other hand, are made to supplement your primary lighting. You can use them to fill in dark areas around your grow room when your primary lights can’t reach. They're also perfect for seedlings, clones, and young plants because they give them enough light to grow without overwhelming them.
For example, the 50 Watt Advance Spectrum All Blue LED Grow Light Panel has over 100 low-wattage chips. These will help fill in gaps of light around your plants during the vegging stage, and can give you enough light for smaller plants like clones and seedlings.
In general, supplemental LEDs are great at giving your plants an additional amount of lumens and wavelengths they need. If your primary light can’t give your plants all the lumens or wavelengths they need, using one or more lower-powered supplemental LED grow lights will help your plants get all the light they need to thrive.
