Supplemental CMH Light Part 2 of 2)
LED lights need to be kept close to the plant to have high PAR (intensity) values and this can cause a shading effect when they are off and the sun is out. Also, the reduced heat they produce is a drawback this time of year as heat is something that is being added anyway so to have it as part of the light, as is the case with the CMH light is an added benefit.
Many will argue that the LED light spectrum is “better” or customizable. To these points, remember this is an outdoor plant that is getting mainly sun and the light is only supplementing light to increase the duration of light exposure. There are some bulb options to get a general spectrum and the 4200K is a daylight/sunlight spectrum.
Also, the customized spectrum sounds great, but the “ideal” light spectrum pattern is not really known so it may feel nice to have dials to adjust, but the adjustments are more of a grower feel good option than increasing plant performance. However, there is active research in this area, so hopefully going forward a more scientific approach to light spectrums and plant performance can be made.
Sure, LED’s will be the future, but for now a CMH would be preferred.
