Usage

• Plants absorb different wavelengths of light that LEDGrowLights provide during the photosynthesis process. You need to place red and blue LEDGrowLights at least 1 foot away from the tops of your plants. However, you can place LED full-spectrum light bulbs 3 inches from the top of your plant's leaves.
