The ARCHIPELAGO full spectrum LED grow lights have been tuned to a specific spectrum range that plants need for optimal growth. So not only are you saving energy by using LED instead of other light sources, but even further efficiencies have been gained in providing spectral peaks in the colors that plants absorb most, while minimizing those they do not. The Archipelago LED grow light is suitable for growing all plants through its full life cycle from seedling to flowering or harvest. When starting plants from seed, a good rule of thumb is to only apply light after the first leaf appears. Also remember to reduce the intensity and keep initial light hours low, while gradually increasing, until your plant begins to grow larger and thrive. Another advantage of LED grow lights is the huge reduction in heat produced. This allows for the light source to be much closer to the plant or plant canopy without risk of burning the plant. Additionally, when being used indoors it removes the need for heat evacuation in the room the plant is being grown in, further saving you money on energy usage.
