A PAR meter can be the best purchase you make for your indoor garden. Many who grow without a PAR meter for their led lights think that simply blasting their plants with tons of light will be beneficial. Focusing on light intensity alone will not give you the results that could be possible. You must also use a PAR light meter to track the color of light.
Plants, including cannabis, flowers, and vegetables all require a specific spectrum of colored light. The only way to know if your plants are getting the right color is by using a PAR light meter. PAR refers to colored wavelengths of light between 400nm and 700nm on the light spectrum.
What a PAR meter does is calculates the proper PAR value from led grow lights so you can adjust the light specifically to its growth stage. In short, a light meter for plants.
Because plants thrive on light and light spectrum, a PAR light meter can tell you exactly what light to give your plant at what time. Thus, having a PAR meter can enhance your plants growing indoors by maximizing beneficial lights that your plants receive.
